by Ariful | May 23, 2026 | UK Updates
Australia remains one of the most lucrative "Anglosphere" markets for UK e-commerce brands and digital agencies. With a familiar language, a high appetite for British goods, and a straightforward GST system, it’s often the first stop for UK businesses scaling outside of Europe. However, as we move through May 2026, the Australian Taxation Office (ATO) has introduced several updates that could catch you off guard if you aren't paying attention.
Don’t let the jargon intimidate you. Whether you are selling via Amazon FBA, running a SaaS platform, or operating a high-growth UK Limited Company with Australian customers, staying compliant is the only way to protect your margins.
This guide breaks down exactly what is changing in 2026, who needs to worry, and how you can keep your focus on selling while we handle the heavy lifting.
The Big Picture: Are You Actually Affected?
Before you panic about complex tax reforms, let’s look at the reality for the average UK seller. If you are a standard e-commerce brand shipping goods from the UK or using Australian-based marketplaces like Amazon, eBay, or Etsy, the "headline" GST rules haven't flipped upside down. The marketplaces still generally handle the collection and remittance of GST for low-value imported goods.
However, the 2026 changes are laser-focused on three specific groups:
- Large International Groups: Those with significant global footprints.
- Sellers with an Australian "Footprint": If you have a local warehouse, staff, or a registered Australian subsidiary.
- Asset Holders: UK entities owning significant stakes in Australian companies.
If you are wondering if your specific setup is still compliant, you can check out our analysis on whether the 2026 Australian tax update really matters for your UK business.
1. Global Minimum Tax (Pillar Two) – The "Big Business" Rule
The most significant shift in the Australian landscape for 2026 is the implementation of the OECD's Global Minimum Tax. This is part of a worldwide effort to ensure multinational corporations pay a fair share of tax wherever they operate.
Who this hits
This applies to groups with an annual global revenue of €750 million or more. If you are a rapidly scaling SME or a digital agency under this threshold, you can breathe a sigh of relief: this won't directly impact your tax bill.
What has changed
For those that do qualify, the first Australian filings under these rules are due by 30 June 2026. Australia has introduced the Income Inclusion Rule (IIR) and a Domestic Minimum Tax (DMT). The goal is to ensure that even if you have complex structures, you are paying at least a 15% effective tax rate in Australia.
2. Public Country-by-Country (CbC) Reporting
Transparency is the theme of 2026. The ATO is rolling out public CbC reporting for large multinationals. This means that for high-profile groups, data regarding revenue, profits, and tax paid in Australia will no longer be private.
For most UK sellers, the impact here is more about reputation and brand perception than a direct financial penalty. If your group is listed or operates at a high volume, your Australian tax data will be more visible to the public. If you are concerned about how your international growth affects your compliance profile, it is essential to understand why cross-border compliance changes the way you scale.
3. Strengthening Foreign-Resident Capital Gains Tax (CGT)
This is where many UK business owners need to pay close attention. The ATO is tightening the net on how foreign residents: including UK individuals and companies: are taxed when they sell Australian assets.
The New Tests
Previously, many UK investors felt safe from Australian CGT unless they were dealing with physical real estate. In 2026, the ATO is applying stricter tests to "land-rich" companies. If you own a significant stake in an Australian company that holds substantial assets in Australia, your eventual exit or sale could trigger a significant tax event in Australia.
What you must do:
- Maintain Accurate Records: Keep your ownership records and cost base details updated daily.
- Consult Before You Sell: Do not wait until the deal is signed. The UK-Australia double tax treaty helps avoid being taxed twice, but you still have to file correctly in both jurisdictions to claim that relief.
4. The 2026 Federal Budget Outlook: What’s Next?
The 2026-27 Federal Budget has set the stage for even more changes that will "kick in" fully over the next 18 months. While you might not feel the sting today, you need to factor these into your three-year growth plan:
- Trust Taxation: Many Australian business structures use discretionary trusts. A new 30% minimum tax on these trusts is on the horizon. If your Australian operations sit within a trust structure, your distribution strategy needs a rethink.
- CGT Discount Changes: The traditional 50% CGT discount is being phased out in favour of an inflation-based discount. For UK sellers holding Australian assets, this could make future exits more expensive.
5. Practical Checklist: Your 3-Minute Action Plan
To ensure your UK business doesn't get caught in the ATO's crosshairs, follow this simple compliance checklist:
- Map Your Footprint: Determine if you have "Nexus" in Australia. Are you just shipping via a marketplace, or do you have a warehouse (3PL) in Sydney? Having stock on the ground changes your GST and income tax obligations instantly.
- Verify Your Revenue: If your global revenue is approaching the €750m mark, you need a Pillar Two readiness project immediately.
- Review Asset Ownership: If you hold shares in an Australian entity, get a valuation and tax review to see how the new foreign-resident CGT rules apply to you.
- Coordinate Your Advice: Ensure your UK accountant is talking to your Australian compliance partner. At Sterlinx Global, we bridge this gap by handling the end-to-end filing requirements across both regions.

FAQ: Australia 2026 Tax Changes
Does the Global Minimum Tax affect small UK e-commerce sellers?
No. The Global Minimum Tax (Pillar Two) only applies to multinational groups with annual global revenues exceeding €750 million. Most SMEs are exempt from this specific reporting requirement.
I sell on Amazon Australia. Do I need to register for GST?
If your turnover from Australian sales exceeds AU$75,000 in a 12-month period, you generally must register for GST. However, if you only sell through "Marketplace Facilitators" like Amazon, they may collect the GST on your behalf for certain imports. It is vital to check your specific business structure to avoid double-taxation or non-compliance.
What is the "Domestic Minimum Tax" in Australia?
It is a new rule starting in 2024/2025 (with first filings in 2026) ensuring that large companies pay at least 15% tax on their Australian profits. It prevents companies from shifting profits to lower-tax jurisdictions.
How does the UK-Australia Double Tax Treaty help me?
The treaty ensures that you aren't taxed on the same income in both countries. If you pay tax in Australia, you can often claim a credit against your UK Corporation Tax. However, you must still file the correct paperwork with the ATO to qualify.
Can Sterlinx Global handle my Australian GST and UK VAT simultaneously?
Yes. We provide a full compliance suite. You provide the data, and we manage the registrations, calculations, and filings for both the UK and Australia, giving you a single point of contact for your global tax needs.
Take the Stress Out of International Expansion
The 2026 changes in Australia prove that the tax world is becoming more digital and more transparent. While the "under 3 minutes" summary gives you the highlights, the actual execution of these filings requires precision.
Don't let a missed filing or an overlooked CGT test derail your Australian growth. We handle the bookkeeping, the GST filings, and the year-end accounts so you can keep your eyes on the market.

by Ariful | May 23, 2026 | US Updates
Staying compliant with USA tax regulations as an international seller is no longer a "set and forget" task. As we move through 2026, the Internal Revenue Service (IRS) and state-level authorities have introduced several critical changes that directly impact non-US residents operating USA LLCs or selling into the American market.
Navigating these shifts is essential to protect your business from hefty penalties and potential bans from major marketplaces. If you are feeling overwhelmed, don't worry. This guide breaks down the most significant updates for 2026, ensuring you remain focused on growth while we handle the operational heavy lifting of compliance.
The 3-Minute Summary: What You Need to Know Now
If you only have a few minutes, here are the three major pillars of USA tax compliance changing in 2026:
- Reporting Thresholds: The IRS is continuing its push for more granular data on payment transactions. If you use payment processors like Stripe or PayPal, expect more frequent 1099-K reporting triggers.
- Sales Tax Base Expansion: Several states, including Georgia, Kansas, and Pennsylvania, have expanded their sales tax reach to include more digital services, SaaS, and B2B products.
- BOI Deadlines: The Beneficial Ownership Information (BOI) reporting requirements under the Corporate Transparency Act (CTA) are now in full force. Failure to file for your US entity can result in criminal penalties and daily fines.
Modernize Your Reporting: The 1099-K and Form 5472 Shift
For international sellers, transparency is the new standard. The IRS has been progressively lowering the reporting threshold for Form 1099-K. This form tracks the "gross amount" of all reportable payment transactions.
For the 2026 tax year, if your business exceeds the updated thresholds (moving toward the long-delayed $600 limit), your payment processor will automatically report these figures to the IRS. This makes it impossible to "fly under the radar."
Maintain accurate records to ensure that the figures reported on your 1099-K align perfectly with your internal bookkeeping. Discrepancies often trigger automated IRS audits, which can be costly and time-consuming for international owners to resolve.
Furthermore, if you operate a Foreign-Owned Single Member LLC (FOSM-LLC), your obligation to file Form 5472 remains a top priority. The penalty for failing to file this form or filing it incorrectly has seen sharp increases in recent years. It is essential to report all "reportable transactions" between the LLC and its foreign owner to avoid a minimum penalty of $25,000 per violation.
Sales Tax 2026: The New "Digital Push"
Sales tax in the USA is managed at the state level, not by the federal government. This means international sellers often face 50 different sets of rules. In 2026, we are seeing a significant trend: Base Expansion.
States are no longer just taxing physical goods. To bolster their budgets, many states are now taxing:
- Digital Downloads & Streaming: If you sell software, e-books, or digital media, you may now have a sales tax nexus in more states than before.
- SaaS and Cloud Software: Subscription-based digital services are becoming a primary target for state revenue departments in Pennsylvania and Wyoming.
- B2B Services: Some professional services provided digitally are now being drawn into the tax net.
Register early if you hit the economic nexus thresholds. Most states trigger a registration requirement once you reach $100,000 in sales or 200 individual transactions within a calendar year. If you sell through marketplaces like Amazon or TikTok Shop, they will often collect and remit the tax for you, but you may still be required to file "zero-tax" returns in many jurisdictions to maintain your good standing.
The FinCEN BOI Deadline: A Non-Negotiable Requirement
Perhaps the most critical update for 2026 is the strict enforcement of the Beneficial Ownership Information (BOI) report. This is not a tax filing; it is a federal requirement managed by FinCEN (the Financial Crimes Enforcement Network).
If you have a US entity (LLC or Corporation) or if your foreign company is registered to do business in a US state, you must report the identities of the individuals who own or control the company.
- New Entities: If you form a US entity in 2026, you generally have only 30 days from the date of formation to file your initial BOI report.
- Existing Entities: If you formed your company before 2024 and haven't filed yet, you are already in the danger zone.
The consequences of ignoring BOI reporting are severe. Willful failure to report can lead to civil penalties of up to $500 for each day the violation continues and criminal penalties including imprisonment. At Sterlinx Global, we integrate BOI compliance into our standard suite to ensure our clients are never exposed to these risks.
Compliance for International Entities: Moving Beyond Simple Filing
Many international sellers believe that "tax compliance" is just something you do once a year. However, in the current 2026 environment, compliance is an ongoing operational process.
To stay ahead of the IRS and state authorities, your business needs a structured approach:
- Continuous Bookkeeping: Daily or weekly bookkeeping is no longer optional. Real-time data allows you to track your nexus thresholds accurately and prepare for 1099-K reconciliations.
- Entity Maintenance: Ensure your US LLC remains "Active" and "In Good Standing" by filing annual reports with the Secretary of State.
- W-8 Series Forms: Keep your W-8BEN or W-8BEN-E forms updated with your banks and marketplaces. This is how you claim tax treaty benefits and avoid the standard 30% flat withholding tax on US-source income.

Frequently Asked Questions (FAQ)
Does a UK company selling into the USA need to pay US income tax?
Generally, if you have no physical presence (employees, warehouse, or office) in the USA, you may be exempt under the UK-US Tax Treaty. However, using Amazon FBA warehouses can sometimes create a "Permanent Establishment." It is essential to have a professional review your specific operational model.
What happens if I miss the BOI filing deadline?
Missing the deadline can result in significant daily fines (up to $500/day) and potential criminal charges. If you have missed a deadline, talk to an expert immediately to rectify the filing.
Do I need a US bank account for Sales Tax?
While not strictly required by law, having a US-based or "virtual" US account (like Wise or Payoneer) makes it much easier to pay state tax departments, as many do not accept international credit cards or wire transfers.
Can I handle my own USA tax filings from abroad?
While possible, it is extremely difficult due to the complexity of multi-state nexus rules and the specific filing requirements for foreign-owned entities. Most international sellers find that the cost of professional compliance is far lower than the cost of IRS penalties.

by Ariful | May 23, 2026 | Canada Updates
Trading between Canada and the United Kingdom has never been more lucrative, but it has also never been more complex. As we move through 2026, the Canada Revenue Agency (CRA) has intensified its focus on the "digital economy," meaning the rules for GST/HST are shifting faster than ever. If you are a UK-based business selling to Canadian consumers, or a Canadian brand expanding into the British market, staying still is the fastest way to fall behind.
Don't worry, compliance doesn't have to be a barrier to your growth. At Sterlinx Global, we specialize in taking the weight of tax calculations and filings off your shoulders. This post will break down why daily monitoring of CRA updates is no longer optional and how you can streamline your operations to stay ahead of the curve.
Understand the $30,000 Threshold Before It Catches You
The most critical number for any cross-border seller in 2026 is C$30,000. This is the threshold for GST/HST registration in Canada. If your worldwide taxable revenues, including digital services and physical goods, exceed this amount over four consecutive calendar quarters, you are legally required to register.
Many UK businesses make the mistake of thinking this threshold only applies to sales within Canada. In reality, the CRA looks at your global footprint to determine your scale. If you are a growing SME or a high-volume ecommerce brand, you likely already hit this milestone months ago.
Register early to avoid penalties. Waiting until the CRA contacts you often results in backdated tax liabilities and heavy fines. By monitoring updates daily, you can identify the exact moment your business crosses the threshold and take proactive steps to register. This ensures you are collecting the correct tax from day one, rather than paying it out of your own profit margins later.
Choose the Right Path: Simplified vs. Normal GST/HST
In 2026, the CRA offers two distinct paths for non-resident sellers. Choosing the wrong one can cost you thousands in unclaimed credits or unnecessary paperwork.
The Simplified Regime (For B2C Focus)
This path was designed specifically for non-resident digital service providers and marketplace sellers. It is easier to set up, but there is a major catch: you generally cannot claim Input Tax Credits (ITCs) to recover the GST/HST you pay on your own business expenses.
The Normal Regime (For Full Compliance)
If you have significant physical operations, hold inventory in Canadian warehouses, or use Canadian service providers, the normal regime is often the better choice. It allows you to claim back the GST/HST you pay on imports and local services. This is essential for maintaining healthy cash flow in a competitive market.
Maintain a flexible strategy. Your business model might start as a simple digital service but evolve into physical product distribution. Daily tax updates will signal when the CRA changes the benefits of one regime over the other, allowing you to pivot your registration status before the next filing deadline.
Master the Provincial Tax Maze (GST vs. HST)
One of the most confusing aspects of selling in Canada is that the tax rate isn't the same everywhere. Depending on where your customer is located, you might need to charge 5% GST, or as much as 15% HST (Harmonized Sales Tax).
In provinces like Ontario, the rate is 13%. In the Atlantic provinces (New Brunswick, Nova Scotia, etc.), it jumps to 15%. If you are selling into British Columbia or Quebec, there are additional provincial taxes (PST/QST) to consider.
Automate your place-of-supply rules. You cannot manually track the location of every customer and apply the correct rate. This is why a tech-driven compliance system is vital. Daily updates ensure that if a province changes its rate, as often happens during budget season, your system updates immediately. This protects you from under-collecting tax and facing a shortfall during your annual audit.
Marketplace Rules: Who Is Actually Responsible?
If you sell through Amazon, Shopify, or eBay, you might assume the platform handles everything. While marketplaces (known by the CRA as "Distribution Platform Operators") do collect and remit tax on many transactions, the rules are nuanced.
In 2026, if you are registered under the Normal GST/HST regime, the responsibility for collecting tax often stays with you, not the platform. If you miscalculate this, you could end up with a double-taxation nightmare or, worse, no tax collected at all.
Verify your platform settings. Don't assume the "default" settings on your marketplace account are compliant with the latest CRA 2026 mandates. Keep your compliance data updated to ensure the platform knows exactly who is responsible for the remittance. For more on this, check out our guide on 7 mistakes you’re making with your Amazon accounting.
The Canada-UK Strategic Link
Since the UK is no longer part of the EU, trade agreements with Canada have become even more vital. Both countries are working to streamline digital trade, but this often leads to "compliance creep", new reporting requirements that pop up with little warning.
Managing sales across both jurisdictions requires a partner who understands both sides of the Atlantic. You might already be compliant with UK VAT, but are you applying the same rigor to your Canadian filings? If you need a refresher on the UK side, read our latest on UK VAT registration for growing SMEs.
Align your reporting periods. Syncing your UK and Canadian accounting cycles can save your team hours of reconciliation work. We help you align these processes so that your year-end filings are a smooth transition rather than a frantic scramble.

Your 2026 Canada-UK Compliance Checklist
To stay ahead of the CRA and ensure your business remains profitable, follow these essential steps:
- Monitor Your Revenue: Track your 12-month rolling revenue. Once you hit C$30,000, start the registration process immediately.
- Audit Your Customer Data: Ensure you are collecting the customer's province at the point of sale to apply the correct GST/HST rate.
- Review Your Registration Type: Evaluate if the "Simplified" regime is still serving you or if the "Normal" regime's tax credits are worth the switch.
- Verify Platform Responsibilities: Check your Amazon/Shopify tax settings against your CRA registration status.
- Book a Compliance Review: Don't wait for an audit to find a mistake.
Keep your business moving. Compliance is the engine of a successful international business, not the brakes. By staying informed and partnering with experts who live and breathe tax updates, you turn a complex obligation into a competitive advantage.

Frequently Asked Questions
What is the GST/HST registration threshold for Canada in 2026?
The threshold remains C$30,000 in taxable sales over four consecutive calendar quarters. This applies to both resident and non-resident sellers, including those in the UK.
Do I need to charge tax on digital services sold to Canadians?
Yes. Under the digital economy rules, most digital products (SaaS, ebooks, online courses) are subject to GST/HST based on the province where the consumer is located.
Can I claim back the tax I pay on imports to Canada?
Only if you are registered under the "Normal" GST/HST regime. The "Simplified" regime for non-residents does not allow for Input Tax Credits (ITCs).
Who collects GST/HST on Amazon.ca?
For many non-resident sellers, the marketplace (Distribution Platform Operator) is responsible. However, if you are registered under the normal regime, the responsibility may shift back to you. Always verify your specific status.
How often should I update my tax rates?
Tax rates can change with provincial budgets. Using a daily update system or a compliance partner like Sterlinx Global ensures you never charge the wrong amount.
by Ariful | May 23, 2026 | UK Updates
Navigating the tax landscape when you are trading cross-border can feel like trying to solve a puzzle with pieces from two different boxes. If you are running a UK Limited Company and selling into the Australian market, or operating a subsidiary Down Under, 2026 is bringing significant shifts you cannot afford to ignore. From the implementation of global minimum tax rules to changes in how you handle employee superannuation, the Australian Taxation Office (ATO) is tightening its grip on compliance.
Don’t worry; we have distilled the most critical updates into this quick-read guide. Whether you are an e-commerce brand, a digital service provider, or a growing SME, here is what you need to know to stay compliant and protect your margins.
Prepare for the Global Minimum Tax (Pillar Two)
The biggest headline for 2026 is Australia’s full commitment to the OECD Pillar Two framework. Starting from 1 July 2026, Australia is integrating rules that establish a 15% global minimum tax rate. While this primarily targets large multinational groups with global revenues exceeding €750 million, its "trickle-down" effect on compliance and reporting is substantial for all international entities.
If your UK Limited Company has an Australian presence, be it a branch or a subsidiary, you must monitor your Effective Tax Rate (ETR). If your local incentives or depreciation rules pull your Australian ETR below 15%, you could face a "top-up tax." This ensures that regardless of where your profits are booked, you are paying at least the global minimum. We recommend reviewing your intercompany pricing and debt levels now to avoid any unexpected tax hits in both the UK and Australia.
Boost Your Cash Flow with the Reintroduced Loss Carry-Back
There is good news for UK companies investing heavily in their Australian expansion. From the income year commencing 1 July 2026, the Australian government is reintroducing the company loss carry-back regime.
This is a powerful tool for your cash flow. If your Australian operations incur a tax loss, you can "carry back" those losses to offset tax you paid in the previous two years. Instead of waiting years to use those losses against future profits, you can claim a cash refund now. For eligible companies with an aggregated global turnover of less than AUD 1 billion, this provides a vital safety net during periods of high capital expenditure or market volatility.
Master the New "Payday Super" Requirements
If you employ staff in Australia or have a local team supporting your digital brand, your payroll processes are about to get a major update. From 1 July 2026, the ATO is introducing Payday Super.
Currently, many employers pay superannuation contributions on a quarterly basis. Under the new rules, you must pay your employees' superannuation at the same time you pay their wages. This change is designed to ensure employees receive their entitlements sooner and to give the ATO real-time visibility into compliance.
For a UK-based management team, this means your payroll systems must be robust. Late payments can result in heavy penalties and interest charges. It is essential to ensure your Australian bookkeeping is integrated with your payroll to handle these frequent disbursements without a hitch.
Secure Your Small Business Instant Asset Write-Off
If your Australian entity qualifies as a small business (generally those with a turnover under AUD 10 million), the AUD 20,000 instant asset write-off has been made permanent starting 1 July 2026.
This allows you to immediately deduct the full cost of eligible depreciating assets, such as computers, office equipment, or tools, costing less than AUD 20,000. For a growing digital agency or e-commerce business, this is a significant incentive to upgrade your local infrastructure while reducing your taxable income in the same year. Just remember: the asset must be first used or installed ready for use within the financial year you claim it.
Don't Forget the GST on Digital Services
While the core GST rate remains steady at 10%, the ATO has increased its focus on enforcement for non-resident suppliers. If your UK Limited Company sells digital services (like SaaS, apps, or streaming) or low-value goods (under AUD 1,000) to Australian consumers, you likely have GST obligations.
You must register for GST if your "Australian-connected" supplies exceed AUD 75,000 per year. Even if you don't have a physical office in Sydney or Melbourne, selling to Australian residents triggers these rules. We see many UK businesses overlook this, leading to backdated tax bills and penalties. Ensure your checkout systems are correctly identifying Australian customers and applying the 10% GST where necessary.
Review Your Thin Capitalisation and Interest Limits
Australia has moved to an EBITDA-based test for limiting interest deductions. This is particularly relevant if your UK parent company provides loans to your Australian subsidiary.
The goal of these rules is to prevent companies from shifting profits out of Australia through excessive interest payments. If your Australian entity is over-leveraged, the ATO may deny your interest deductions, effectively increasing your tax bill. In the context of the new Pillar Two rules, this could also impact your Effective Tax Rate. We suggest reviewing your intercompany financing agreements to ensure they align with these stricter EBITDA thresholds.

Frequently Asked Questions (FAQ)
What is the GST registration threshold for UK companies selling in Australia?
You must register for Australian GST if your annual turnover from sales connected with Australia is AUD 75,000 or more. This includes sales of digital services and low-value goods to Australian consumers.
When does the new Payday Super rule take effect?
The Payday Super requirement, which mandates that superannuation be paid at the same time as wages, starts on 1 July 2026.
Can a UK company claim the Australian instant asset write-off?
Yes, if your Australian entity (subsidiary or branch) qualifies as a small business with an aggregated turnover of less than AUD 10 million, you can claim the AUD 20,000 instant asset write-off for eligible assets.
What is the corporate tax rate in Australia for 2026?
The base corporate tax rate for small to medium businesses (turnover under AUD 50 million) is generally 25%, while the standard rate for larger entities is 30%. However, with the Pillar Two implementation, a 15% global minimum effective tax rate also applies.
How does the loss carry-back regime help my business?
The loss carry-back regime allows companies to use current tax losses to offset tax paid in previous years, resulting in a cash refund from the ATO. This is particularly helpful for managing cash flow during expansion.
by Ariful | May 23, 2026 | USA Accounting
Scaling your business into the United States is a significant milestone for any international brand. Whether you are an e-commerce seller on Amazon, a SaaS provider, or a growing digital agency, the US market offers unparalleled reach. However, that growth comes with a complex web of compliance requirements that change almost daily.
In 2026, "Economic Nexus" has become the primary regulatory hurdle for non-US entities. Unlike traditional tax rules that required a physical office or warehouse, modern state tax laws trigger obligations based solely on your sales volume. If you aren't monitoring these thresholds daily, you could be accruing massive liabilities without even knowing it.
At Sterlinx Global, we focus on the operational execution of your tax compliance. We don't just tell you the rules; we manage the filings and data so you can focus on scaling. This guide breaks down why daily monitoring is your best defense against costly IRS and state tax pitfalls.
The 2026 Shift: Why Thresholds are Changing
State governments across the US are constantly refining their tax codes to capture revenue from remote and international sellers. For a long time, many states used a "200 transaction" rule as a trigger for sales tax registration. As of 2026, we are seeing a massive shift away from this model.
States like Illinois, Utah, and Kentucky have officially removed or are in the process of removing their transaction-count thresholds. Instead, they are moving toward a simplified, revenue-based model, typically $100,000 in gross sales. While this sounds simpler, it actually requires more precise tracking.
Why this matters for you:
- Illinois: As of January 1, 2026, you no longer need to worry about the 200-transaction count. If you hit $100,000 in retail sales in a 12-month period, you must register.
- Kentucky: Following suit in August 2026, the 200-transaction rule disappears, leaving only the $100,000 revenue trigger.
- Simplification is a trap: While you don't have to count every small order, missing that $100,000 mark by even a few dollars can lead to back-dated tax assessments and heavy penalties.
Understand Economic Nexus for International Sellers
If you are a non-US company (such as a UK Limited Company, a Canadian Corporation, or an Australian entity), you might think US state taxes don't apply to you. This is a dangerous misconception. Economic Nexus is about where your customers are, not where your business is registered.
Most US states do not offer "treaty protection" for sales tax. While a tax treaty might help with federal income tax, it does nothing to protect you from the Department of Revenue in California or New York. If your US-destination sales exceed a state’s threshold, you are legally required to:
- Register for a Sales Tax Permit in that state.
- Collect the correct tax rate from your customers at checkout.
- Remit (pay) that tax to the state on a monthly or quarterly basis.
Scaling without monitoring these numbers is like driving a car without a speedometer, you won't know you've broken the limit until you get the fine.
Avoid the "Marketplace Facilitator" Confusion
Many of our clients sell through platforms like Amazon, Etsy, or Walmart. These platforms are "Marketplace Facilitators," meaning they collect and remit sales tax on your behalf for sales made on their platform.
However, here is the pitfall: Marketplace sales still count toward your nexus threshold in most states.
Even if Amazon collects the tax, those sales could push you over the $100,000 limit in a state like Florida or Texas. If you then start selling through your own Shopify store or direct-to-consumer website, you are suddenly liable for tax on those direct sales. Without daily monitoring of your aggregate sales across all channels, you risk missing the registration deadline.
If you are struggling to reconcile your marketplace reports with your direct sales, Contact us to see how our structured compliance system can automate this tracking for you.
IRS Pitfalls vs. State Tax Obligations
While "Nexus" is a state-level issue, the IRS manages federal obligations. For international sellers, the IRS focus is on information reporting and federal income tax.
In 2026, the IRS has increased its focus on digital assets and cross-border payments. If you operate as a foreign corporation (Form 1120-F) or have "Effectively Connected Income" (ECI) in the US, your reporting requirements are stringent.
Common IRS pitfalls for international sellers include:
- Form 1099-K Discrepancies: The IRS receives data from payment processors. If the revenue reported on your 1099-K doesn't match your tax filings, it triggers an automatic red flag.
- Failure to File Protective Returns: Even if you don't owe federal tax due to a treaty, failing to file a "protective" return can result in the IRS denying your right to claim deductions later if they audit you.
- Incorrect Withholding: If you are providing digital services to US clients, you must ensure your W-8BEN-E forms are current to avoid a flat 30% withholding on your revenue.
How Daily Monitoring Saves Your Bottom Line
Compliance is not a once-a-year task. It is a daily operational requirement. Waiting until year-end to check your state-by-state sales volume is a recipe for disaster.
By implementing a daily monitoring system, we help you:
- Identify Nexus Before It Happens: We track your "approaching thresholds" so you have time to register before the first taxable sale occurs.
- Maintain Accurate Bookkeeping: US tax compliance relies on clean data. Our team ensures your daily transactions are categorized correctly to prevent overpaying or underpaying tax.
- Avoid Late Filing Penalties: US states are aggressive with late fees. Even a "zero return" (filing when you had no sales but are registered) can carry a $50+ penalty for being just one day late.
At Sterlinx Global, we take the data you provide and handle the ongoing compliance. We aren't just consultants; we are the engine that keeps your US operations running smoothly. Whether you're dealing with Amazon accounting issues or scaling a new digital brand, our system is built to handle the volume.

Frequently Asked Questions
Does the 200-transaction rule still apply in 2026?
It depends on the state. While major states like Illinois and Utah have removed it, several others (like Arkansas and New Jersey) still use the "100,000 or 200 transactions" trigger. Daily monitoring is essential to know which rules apply to your specific sales footprint.
I only sell on Amazon. Do I still need to worry about US state tax?
Yes. While Amazon collects the tax for you, those sales contribute to your Economic Nexus. If you reach a threshold, you may still need to register for a sales tax permit, file "informational" returns, and pay any franchise or income taxes the state requires.
What happens if I miss a registration deadline?
States can charge back-taxes, interest, and penalties starting from the day you crossed the threshold. In some cases, these fines can exceed the actual tax owed. This is why we emphasize "daily monitoring" to catch thresholds before they are crossed.
Can a UK company be audited by a US state?
Absolutely. US states are increasingly using data-sharing agreements with marketplaces and customs to identify high-volume international sellers who are not registered for tax.
Do I need a US bank account to pay these taxes?
Not necessarily, but it makes the process significantly easier. Many state systems are designed only for US bank accounts. Part of our service at Sterlinx Global involves facilitating these payments and filings on your behalf, regardless of where your company is based.
