by Ariful | May 23, 2026 | US Updates
Selling into the United States is the ultimate goal for many international e-commerce brands and digital businesses. The market is vast, the consumers are ready, and the growth potential is limitless. However, the complexity of the US tax system can feel like a steep mountain to climb. Between federal IRS rules and the ever-changing landscape of state-level sales tax, staying compliant is no longer a "once a year" task, it is a daily requirement.
If you are a UK Limited Company, a Canadian Corporation, or an Australian entity trading in the USA, you need a structured approach to tax compliance. Rules change, thresholds shift, and reporting requirements evolve. This guide breaks down the essential 2026 updates you need to know and how to manage them without losing focus on your core business.
Separate Federal from State: The First Rule of US Compliance
Before diving into the latest updates, it is essential to understand that the US has two distinct layers of tax: Federal (IRS) and State (Department of Revenue).
The IRS handles federal income taxes, reporting forms like the 1099, and international treaties. State governments, on the other hand, manage Sales Tax and economic nexus. Don’t worry; while it sounds complicated, the key is knowing which rule applies to which activity.
For international sellers, most of the "daily" friction comes from Sales Tax, but 2026 has brought several federal reporting changes that could impact your operational costs and data requirements.
2026 Federal IRS Updates: What International Sellers Must Know
The IRS has introduced several updates for the 2026 tax year that aim to increase transparency and modernize reporting. If you use US-based payment processors or trade in digital assets, these rules apply directly to you.
Mastery of the 1099-K Reporting Thresholds
For several years, there has been back-and-forth regarding the threshold for Form 1099-K, which payment platforms like Stripe, PayPal, and Amazon use to report your gross sales to the IRS. For 2026, the threshold remains at $20,000 and 200 transactions.
While this is higher than the previously proposed $600 limit, it still means the IRS is receiving a direct feed of your US sales data. Ensuring your internal bookkeeping matches these 1099-K forms is critical to avoid "red flag" audits.
New Digital Asset Reporting (Form 1099-DA)
Starting in the 2025 tax year (reporting in early 2026), brokers are now required to issue Form 1099-DA for digital asset transactions. If your e-commerce business accepts cryptocurrency or uses digital wallets for US trade, you must maintain precise records of your cost basis and transaction dates. This update is part of a broader push to bring digital assets into the traditional tax fold.
The 1% Federal Remittance Fee
Effective January 1, 2026, a new 1% federal fee applies to certain money transfers sent from the US to international locations when funded by cash or money orders. Luckily, most digital businesses use electronic transfers, wires, or app-based funding, which are currently exempt. However, it highlights the importance of using modern neo-banking solutions to keep your cross-border costs low and your reporting clean.
Navigating State Sales Tax Nexus in 2026
Sales Tax remains the biggest hurdle for international sellers. In the US, there is no national VAT. Instead, you deal with over 45 different state tax jurisdictions, each with its own rules for "Nexus", the link that requires you to collect and remit tax.
Monitor Economic Nexus Daily
Economic nexus is triggered by your sales volume. Most states use a threshold of $100,000 in annual sales into that specific state. Some states have removed the "200 transaction" count, focusing purely on revenue.
Because you can cross these thresholds at any moment, you need a system that monitors your sales data daily. If you wait until the end of the quarter to check, you might already owe thousands in uncollected tax.
Inventory and Physical Nexus
If you use a 3PL or Amazon FBA, storing inventory in a US warehouse often creates physical nexus. Even if you haven't sold $100,000 in that state, the presence of your goods usually triggers a registration requirement. It is vital to track where your inventory is held to stay ahead of these obligations. You can read more about common US sales tax mistakes to ensure you aren't falling into the standard traps.
Operationalize Your Compliance with a Structured System
At Sterlinx Global, we don't believe in the "traditional" tax advisory model where you meet once a year to discuss the past. For a fast-growing SME or e-commerce brand, that is far too slow. We operate as a Global Tax Compliance Suite.
The goal is simple: You provide the data, we complete the compliance.
Daily Data Integration
To succeed in the US market, your data needs to flow seamlessly from your marketplace (Amazon, Shopify, TikTok Shop) to your accounting system. We specialize in taking that raw data and turning it into accurate, ready-to-file reports. This "daily" mindset ensures that when a deadline hits, the work is already done.
Filing and Deadlines
Missing a US tax deadline can result in heavy penalties and the revocation of your ability to trade in certain states. We handle the heavy lifting:
- Sales Tax Registrations: Getting you registered in the right states at the right time.
- Monthly/Quarterly Filings: Calculating exactly what is owed and ensuring it is paid on time.
- Year-End Accounts: For international entities like USA LLCs, ensuring your federal filings are accurate and compliant with the latest 2026 IRS adjustments.
Why International Sellers Choose Sterlinx Global
Managing US compliance from the UK, Canada, or Australia is challenging due to time zones, different terminology, and the sheer volume of state-level rules. This is why we have built a tech-driven system designed specifically for cross-border traders.
Whether you need a full-suite accounting service for your UK Limited Company and its US branch, or standalone US Sales Tax management, we provide the flexibility to scale. We understand the nuances of cross-border VAT and Sales Tax, ensuring you aren't double-taxed or left exposed to audits.

USA Tax Updates 2026: Frequently Asked Questions
Does the IRS handle my US Sales Tax?
No. The IRS handles federal income tax. Sales Tax is managed individually by each US state. You must register and file with each state where you have nexus.
What is the 1099-K threshold for 2026?
The current threshold for 1099-K reporting is $20,000 in gross sales and 200 transactions. This is the data that platforms like Amazon or Stripe report to the IRS.
What is Economic Nexus?
Economic nexus is a requirement to collect sales tax based on your sales volume into a state, typically $100,000 per year, even if you have no physical presence there.
Do I need a US bank account to pay my taxes?
While not always strictly required, having a US-compatible payment solution or a neo-bank account makes paying state and federal taxes significantly easier and cheaper.
How does Sterlinx Global help international sellers?
We provide a structured compliance service. You provide us with your sales and expense data, and we handle the bookkeeping, tax calculations, and filings for both state sales tax and federal requirements.
Are there new rules for digital assets in 2026?
Yes, the IRS now requires the use of Form 1099-DA to report transactions involving digital assets like cryptocurrency, starting with the 2025 tax year (reported in 2026).
by Ariful | May 23, 2026 | Canada Updates
If you are running a UK Limited Company and selling into North America, you’ve likely noticed that the Canadian Revenue Agency (CRA) hasn't been sitting still. In fact, 2026 has already seen some of the most significant shifts in Canadian tax law in over a decade. From the sudden repeal of the Digital Services Tax (DST) to new electronic filing mandates, keeping up with Canada’s daily tax updates has become a full-time job for international sellers.
Don’t worry, this is exactly why we track these changes for you. At Sterlinx Global, we specialize in ensuring that your cross-border compliance is handled daily, so you don't have to stress about the "what ifs" of Canadian tax law.
Here is why the latest updates from the CRA matter for your business and how you can stay ahead of the game.
The Big News: The Digital Services Tax (DST) Is Gone
The most significant update of 2026 came on March 26, when the Canadian government officially received Royal Assent to repeal the Digital Services Tax Act. For years, the 3% DST was a looming cloud over large digital businesses, platforms, and e-commerce giants.
This repeal means the 3% levy on revenue from digital services is no longer an ongoing obligation. While this is a massive win for simplicity, it doesn’t mean you are off the hook for Canadian taxes. It simply shifts the focus back to the primary compliance pillar: GST/HST.
Master the CAD 30,000 Small Supplier Threshold
For most digital service providers and e-commerce brands, the "Small Supplier" threshold is the magic number. In Canada, you are generally required to register for GST/HST once your taxable sales to Canadian customers exceed CAD 30,000 within any rolling 12-month period.
This is not a calendar year calculation. It is a "daily" monitoring task. If you hit that threshold today, you need to register. Failing to do so can lead to retroactive tax assessments and heavy penalties. By staying on top of your daily sales data, we ensure that you register at exactly the right time to avoid late-filing fines.
Use the Simplified GST/HST Regime for Digital Sales
If you are a non-resident vendor selling digital products (like SaaS, apps, or online courses) or a platform operator, the CRA offers a simplified GST/HST registration. This is designed to make your life easier by reducing the administrative burden.
- B2C Sales: You must charge GST/HST to Canadian consumers.
- B2B Sales: If your customer provides a valid GST/HST number, you generally do not charge the tax, and they self-assess.
- Rates: You must apply the correct rate based on the customer’s province. These range from 5% GST in Alberta to 15% HST in Atlantic Canada.
Navigating these rates across different provinces can be a headache. This is why we integrate our tax calculations directly with your data, ensuring the right amount is collected every time. If you've been struggling with your platform's tax settings, you might find our guide on 7 mistakes you’re making with your Amazon accounting particularly helpful.
E-Filing Is Now Mandatory for Everyone
As of early 2026, the CRA has made it clear: paper is out. Every GST/HST registrant (with very few exceptions) must file their returns electronically. If you try to mail in a paper return, you are likely to trigger a penalty.
Furthermore, if your tax payment is CAD 10,000 or more, it must be made through an electronic payment method. This shift toward a fully digital tax ecosystem means your bookkeeping must be precise and your data must be ready for e-filing at a moment's notice.
Avoid the Most Common CRA Filing Errors
We see businesses make the same mistakes repeatedly when trying to manage their Canadian compliance alone. Most of these errors are easily avoidable with the right structured system.
- Missing the 1-Month Deadline: For most monthly and quarterly filers, your return and payment are due exactly one month after the end of your reporting period.
- Incorrect Provincial Rates: Charging 5% when you should have charged 15% creates a liability that comes out of your own profit margins.
- Ignoring Provincial Sales Taxes (PST/QST): Some provinces, like British Columbia and Quebec, have separate systems that may require additional registrations.
If you are worried about your current filings, check out our deep dive into 7 mistakes you’re making with CRA tax filings.
Corporate Income Tax: Do You Have a Permanent Establishment?
One of the biggest questions we get from UK Limited Companies is whether they owe corporate income tax in Canada. Generally, if you sell digital products from the UK and have no physical presence (employees, offices, or servers) in Canada, you likely do not have a Permanent Establishment (PE).
However, this is a nuanced area. While you might be exempt from corporate income tax under a tax treaty, you are still fully responsible for GST/HST. The absence of an income tax liability does not mean you can ignore the CRA.
Your 2026 Canadian Compliance Checklist
To stay compliant with the latest changes, follow this simple checklist:
- Monitor Revenue: Check your 12-month rolling revenue daily to see if you've hit the CAD 30,000 mark.
- Verify GST Numbers: Ensure you are validating Canadian business customer GST numbers to correctly exempt B2B sales.
- Switch to E-Payments: Set up your banking to handle electronic transfers to the CRA for amounts over CAD 10,000.
- Update Your Invoicing: Ensure your invoices display your GST/HST number and the correct provincial tax rate.
Staying compliant in a foreign market shouldn't be a barrier to your growth. At Sterlinx Global, we take the operational weight of compliance off your shoulders. We don't just give advice; we handle the bookkeeping, the calculations, and the filings on your behalf.

Frequently Asked Questions (FAQ)
What is the GST/HST registration threshold in Canada for 2026?
The threshold remains CAD 30,000 in taxable supplies over any rolling 12-month period. This applies to both resident and non-resident businesses selling to Canadian customers.
Is the Digital Services Tax (DST) still active in Canada?
No. As of March 26, 2026, the Digital Services Tax Act has been repealed. Businesses are no longer required to pay the 3% levy on digital service revenue.
Do I need to file my Canadian tax returns electronically?
Yes. As of 2024 and through 2026, the CRA requires all GST/HST registrants (except for specific charities) to file their returns and make large payments (over CAD 10,000) electronically.
How do I know which tax rate to charge in Canada?
The tax rate depends on the province of the customer. It varies from 5% GST (in provinces like Alberta) to 15% HST (in provinces like Nova Scotia and New Brunswick).
Does Sterlinx Global handle Canadian GST/HST filings?
Yes. We provide a full compliance suite that includes bookkeeping, tax calculations, and GST/HST filings for UK Limited Companies and international entities selling in Canada.
by Ariful | May 23, 2026 | Australia Updates
The Australian Taxation Office (ATO) is entering a new era of digital enforcement. If you are running a UK Limited Company with Australian operations, a local SME, or a digital business scaling in the Australian market, the compliance landscape is shifting beneath your feet. As of May 2026, the ATO has integrated real-time data matching across payroll, marketplaces, and banking systems.
Managing your tax obligations is no longer a quarterly check-in; it is a daily operational requirement. This update breaks down the most critical changes you need to address this month to avoid penalties and ensure your business remains compliant.
The Shift to Payday Super: No More Quarterly Buffers
The biggest change on the horizon, and the one you must prepare for in May 2026, is the transition to Payday Super. While the official start date for mandatory real-time payments is 1 July 2026, the ATO expects businesses to have their systems and cash flow projections ready now.
Align Your Cash Flow with Pay Dates
Traditionally, Australian employers could hold onto superannuation contributions and pay them quarterly. This provided a significant cash flow buffer. From July, you must pay superannuation at the same time you pay wages. This means if you pay your staff weekly, you pay their super weekly.
Real-Time Monitoring via STP Phase 2
The ATO is already using Single Touch Payroll (STP) Phase 2 data to monitor these obligations. By May 2026, the data-matching algorithms are fully optimized. If your STP reports show a wage payment without a corresponding superannuation accrual and subsequent payment, it will trigger an automated flag.
Don't worry, this is why we emphasize structured, daily bookkeeping. Waiting until the end of the month to reconcile your payroll will result in missed deadlines and non-deductible Super Guarantee Charge (SGC) penalties.
Marketplace and Platform Reporting: The ATO is Watching Your Sales
If you sell through Amazon, eBay, Shopify, or freelance platforms like Upwork and Uber, the ATO's "Sharing Economy Reporting Regime" is now in full swing.
Automated Cross-Matching
Digital platforms are now required to report transaction data directly to the ATO. In May 2026, the ATO is cross-referencing this data against your Business Activity Statements (BAS) and Income Tax Returns. If the sales reported by Amazon don't match the GST you've declared, you can expect an automated audit letter.
Maintain Accurate Digital Records
To avoid these discrepancies, you must ensure your ABN and GST registration details are perfectly aligned across all platforms. At Sterlinx Global, we specialize in ensuring your marketplace data is pulled daily and reconciled against your bank feeds, so your ATO reporting is always accurate.
New Personal Tax Cuts: Update Your Payroll Software Now
Starting 1 July 2026, a new set of personal income tax cuts will take effect. While this is great news for your employees, it creates an immediate administrative task for you in May and June.
Update Tax Tables Before July 1
The PAYG withholding rates are changing. You must ensure your payroll software is updated with the 2026-27 tax tables before your first pay run in July. Failing to update these tables will result in incorrect withholding, which can lead to significant headaches during year-end reconciliations.
Compliance Checklist for Payroll:
- Verify STP Phase 2 Compliance: Ensure every employee detail (TFN, date of birth, and income type) is accurate.
- Set the Super Rate to 12%: The super guarantee rate remains at 12% for the 2025-26 and 2026-27 financial years.
- Audit Your Allowances: The ATO is specifically looking at how allowances (travel, laundry, car) are reported under the new STP rules.
The $20,000 Instant Asset Write-Off is Now Permanent
For SMEs with an annual turnover of less than $10 million, there is a significant benefit in the May 2026 update. The Government has moved to make the $20,000 instant asset write-off a permanent fixture of the tax code.
Invest in Your Business Growth
This means you can immediately deduct the full cost of eligible assets, such as computers, office furniture, or specialized equipment, costing less than $20,000. If you are planning a technology upgrade, doing so before the 30 June year-end can provide a powerful deduction for your 2025-26 tax return.
Keep Detailed Tax Invoices
Remember, the ATO requires a valid tax invoice for every claim. In a world of digital enforcement, "near enough" is no longer good enough. Every deduction must be supported by a digital record that matches your bank transactions.
Why Daily Compliance is Your Only Shield
The recurring theme of the May 2026 updates is immediacy. The ATO is moving away from retrospective audits and toward real-time intervention.
Avoid Debt Disclosure to Credit Bureaus
The ATO has increased its powers to disclose significant tax debts (over $100,000) to credit reporting bureaus. A late BAS or unpaid super balance could now directly impact your business's ability to secure financing or trade with suppliers.
Sterlinx Global: Your Global Tax Compliance Suite
This is where the traditional "once-a-year accountant" model fails. You need a partner that handles your compliance as it happens. At Sterlinx Global, we don't just advise; we execute.
You provide the data, and we complete your bookkeeping, tax calculations, GST filings, and payroll on an ongoing basis. Whether you are managing a UK Limited Company with Australian sales or a fast-growing local SME, we ensure your data is "ATO-ready" every single day.
Action Plan for May 2026
To keep your business on the right side of the ATO, follow this structured checklist:
- Review Cash Flow for Payday Super: Calculate what your weekly or fortnightly super liability will look like starting July 1.
- Reconcile Marketplace Sales: Check your Amazon or Shopify payouts against your accounting software to ensure no income is being missed.
- Confirm Payroll Software Updates: Reach out to your software provider to ensure the 1 July 2026 tax tables are ready to go.
- Digitize Every Receipt: Use a tool like Dext or Hubdoc to ensure every expense has a digital tax invoice attached.
- Schedule a Compliance Review: If you are unsure if your current setup meets the 2026 requirements, now is the time to act.
The 2026 tax landscape is complex, but it doesn't have to be overwhelming. By staying organized and utilizing a tech-driven compliance partner, you can focus on scaling your business while we handle the data.
Don't wait for an ATO notification to find out you've missed a change. Stay proactive, stay compliant, and keep growing.

FAQ: ATO Reporting Changes May 2026
When does Payday Super actually start?
The mandatory requirement for employers to pay superannuation at the same time as wages begins on 1 July 2026. However, you should be preparing your systems and cash flow in May 2026.
What is the current Super Guarantee rate for May 2026?
The rate is currently 12%. It was increased to 12% on 1 July 2025 and remains at this level for the 2026 financial year.
Does the ATO really see my Amazon or Shopify sales?
Yes. Under the Sharing Economy Reporting Regime, digital platforms are legally required to report transaction data to the ATO. Discrepancies between these reports and your BAS will likely trigger an audit.
Can I still claim the $20,000 instant asset write-off?
Yes, for small businesses with an annual turnover under $10 million, the $20,000 threshold has been made permanent for eligible assets.
How do I update my payroll for the July 2026 tax cuts?
Most cloud-based payroll systems (like Xero or QuickBooks) will update tax tables automatically. However, you must verify that these updates are applied before your first pay run in July 2026.

UK Accounting Update: Preparing Your Ecommerce Business for 2026 Digital Rules
The landscape of UK tax compliance is undergoing its most significant transformation in decades. By April 2026, the way you record income and report to HMRC will shift from a once-a-year task to a continuous, digital-first process. For fast-growing ecommerce brands and digital SMEs, this change isn’t just about avoiding fines: it is an opportunity to build a more scalable, transparent financial foundation.
Staying ahead of these changes ensures your business remains agile as you scale across borders. Whether you are selling on Amazon, Shopify, or through a bespoke digital agency model, understanding the 2026 digital compliance roadmap is essential for your long-term success.
Understand the MTD for ITSA Rollout
Making Tax Digital (MTD) for Income Tax Self Assessment (ITSA) is the headline change arriving on 6 April 2026. If you are a self-employed business owner or a sole trader with a total qualifying income of over £50,000, you will be required to follow these new rules.
Instead of filing one annual Self Assessment tax return, you must keep digital records of all business transactions and send quarterly updates to HMRC using MTD-compatible software. This move towards real-time reporting helps you stay on top of your tax liabilities throughout the year, preventing unpleasant surprises when the final bill arrives.
Pivot from Spreadsheets to Integrated Software
If you are still managing your accounts on manual spreadsheets or paper ledgers, now is the time to transition. Under the 2026 rules, “digital links” are mandatory. This means your data must flow seamlessly from your sales platforms (like Shopify or Amazon) into your accounting software without manual data entry.
Register for a digital-first accounting system like Xero or QuickBooks now. These platforms integrate directly with marketplace APIs and payment gateways like Stripe or PayPal. This automation reduces human error, saves you hours of manual reconciliation every week, and ensures you are fully compliant with HMRC’s digital record-keeping requirements. To get started, you can review our quick start guide to UK accounting.
Automate Your VAT and Cross-Border Filings
For ecommerce businesses trading globally, compliance becomes significantly more complex. While MTD focuses on UK reporting, you must also consider international obligations like the EU’s VAT in the Digital Age (ViDA) initiative and global sales tax thresholds.
Maintain a centralized compliance suite to handle your VAT registration and filings across multiple jurisdictions. If you sell into the EU, Germany, or France, ensure your software can handle varied VAT rates and domestic reporting requirements. Relying on a structured compliance partner like Sterlinx Global allows you to focus on growth while we ensure your daily transactions are calculated and filed accurately. You can read more about why HMRC’s 2026 VAT updates matter for ecommerce.
Prepare for Quarterly Reporting Cycles
The shift to quarterly reporting means your bookkeeping must be current at all times. You can no longer wait until the end of the year to organize your receipts and invoices.
- Keep records updated daily: Use automated feeds to pull bank transactions and sales data into your ledger.
- Submit quarterly updates: Send a summary of your income and expenses to HMRC every three months.
- Finalize with a Final Declaration: Replace your traditional tax return with a year-end declaration that confirms your total tax liability.
Don’t worry if this sounds overwhelming. Moving to a structured, tech-driven system early will make these deadlines feel like a natural part of your business operations. For a deeper dive, check out our MTD for Income Tax 101 guide.
Your 2026 Compliance Checklist
To ensure your ecommerce business is ready for the upcoming digital mandates, follow these actionable steps:
- Calculate your income: Determine if your total gross income will exceed the £50,000 threshold by April 2026 (or £30,000 by April 2027).
- Audit your software: Verify that your current accounting tools are officially recognized as “MTD-compatible” by HMRC.
- Bridge the digital gaps: Ensure your ecommerce store and payment processors are digitally linked to your accounting ledger.
- Set up a tax reserve: Use your real-time data to set aside the correct amount of tax every month to maintain healthy cash flow.
- Seek expert support: Partner with a compliance suite that specializes in digital businesses and cross-border scaling.

Frequently Asked Questions
When does MTD for Income Tax start?
The mandate begins on 6 April 2026 for those with qualifying income over £50,000. It extends to those earning over £30,000 on 6 April 2027.
Does MTD apply to UK Limited Companies?
Currently, MTD is mandatory for all VAT-registered UK Limited Companies. MTD for Corporation Tax has not yet been mandated for a 2026 start, but businesses are encouraged to adopt digital record-keeping now to prepare for future rollouts.
Can I still use Excel for my accounting?
You can use spreadsheets only if they are digitally linked to HMRC via approved bridging software. However, for a scaling ecommerce business, a dedicated accounting platform is recommended for better automation and accuracy.
What happens if I miss a quarterly update?
HMRC is introducing a points-based penalty system for late submissions. Keeping your digital records updated daily is the best way to avoid these fines and maintain a positive compliance history.
by Ariful | May 21, 2026 | US Updates
Starting a USA LLC as a UK business owner is one of the smartest ways to scale your e-commerce or digital services brand into the world’s largest market. It gives you instant credibility, access to US payment gateways like Stripe and Shopify Payments, and a foothold in a massive economy. However, the “compliance” side often feels like a dark cloud hanging over your growth.
You might have heard horror stories of $25,000 IRS penalties or complex state tax traps. Don’t worry; it is essential to remember that while the US tax system is different from the UK, it is entirely manageable when you have a structured system in place.
At Sterlinx Global, we don’t just advise you on what to do; we handle the heavy lifting. We take your data and complete your compliance on an ongoing basis, ensuring you never miss a deadline. This guide breaks down exactly what you need to stay on the right side of the IRS and state authorities in 2026.
Identify Your LLC Tax Status First
Before you can file a single form, you need to know how the IRS views your business. Most UK owners opt for a Single-Member LLC (SMLLC). By default, the IRS treats this as a “disregarded entity.” This means the business is ignored for federal income tax purposes, and the profits “flow through” to you, the owner.
However, because you are a non-US resident (a “foreign person”), your LLC is officially classified as a Foreign-Owned US Disregarded Entity. This classification triggers specific reporting requirements that are non-negotiable. If you have partners, your LLC is likely treated as a Partnership, which comes with its own set of forms (Form 1065). Understanding this distinction is the foundation of your compliance journey.
Master the IRS Federal Filing Requirements
For a UK-based owner of a US LLC, the IRS is primarily interested in transparency. They want to know who owns the company and what money is moving in and out. This is where most people get caught out, as even if your LLC made zero profit, you might still have a filing obligation.
File Form 5472 and Pro Forma 1120
This is the “big one.” Every foreign-owned US disregarded entity must file Form 5472 along with a pro forma Form 1120. This isn’t a tax return in the traditional sense; it is an information return. You are required to report “reportable transactions” between the LLC and its foreign owner (you).
Reportable transactions include:
- Capital contributions: Moving your own money into the LLC to get started.
- Distributions: Taking profit out of the LLC to your UK bank account.
- Loans: Lending money to the business or vice versa.
- Service fees: Paying yourself or your UK Ltd company for management or admin.
Why this matters: The penalty for failing to file Form 5472, or filing it incorrectly, is a staggering $25,000 per year. Even if your business is small, the IRS does not have a “small business” exemption for this fine. We ensure these forms are prepared accurately and submitted to the IRS in Ogden, Utah, well before the April 15th deadline.
Submit Your BOI Report to FinCEN
A significant change that took full effect by 2026 is the Beneficial Ownership Information (BOI) reporting requirement. This is handled by FinCEN (the Financial Crimes Enforcement Network), not the IRS.
Under the Corporate Transparency Act, almost every LLC must disclose who actually owns and controls the company. As a UK owner, you must provide your full name, date of birth, residential address, and a copy of your passport.
- New LLCs: You must file this report within 30 days of formation.
- Changes: If you move house or change your passport, you must update the report within 30 days.
Failing to comply with BOI reporting can lead to civil penalties of up to $500 per day and even criminal charges. We include BOI management as part of our full-suite compliance service to keep your entity in good standing.
Navigate the Sales Tax Nexus Maze
If you are selling physical goods (e-commerce) or certain digital services into the USA, you cannot ignore Sales Tax. Unlike VAT in the UK, which is a national tax, US Sales Tax is managed at the state level. There are over 11,000 different tax jurisdictions in the US, but you only need to care about the ones where you have “Nexus.”
Physical Nexus vs. Economic Nexus
You trigger Sales Tax obligations in two main ways:
- Physical Nexus: You have inventory in a warehouse (like Amazon FBA), an employee, or an office in a specific state. If your goods are sitting in a California warehouse, you likely have physical nexus there.
- Economic Nexus: You hit a certain threshold of sales into a state, even without a physical presence. The most common threshold is $100,000 in sales or 200 transactions in a calendar year, but this varies by state (e.g., New York, Texas, and Florida all have different rules).
Register and collect: Once you hit nexus, you must register for a Sales Tax Permit in that state, collect tax from your customers, and file regular returns. If you sell on marketplaces like Amazon or TikTok Shop, they may collect the tax for you (Marketplace Facilitator rules), but you often still need to file “zero” returns to stay compliant. You can learn more about common mistakes in our guide on 7 mistakes you’re making with US sales tax.
Don’t Forget State-Level Maintenance
Your LLC is “born” in a specific state: usually Delaware, Wyoming, or New Mexico for UK owners. Each state has its own “maintenance” requirements to keep the LLC active.
- Annual Reports: Most states require a yearly filing to update your address and member details.
- Franchise Tax: This is a “privilege tax” for the right to do business in that state. In Delaware, for example, it’s a flat fee for LLCs due by June 1st.
- Registered Agent: You are legally required to maintain a Registered Agent with a physical address in your formation state to receive legal documents.
If you fail to pay your franchise tax or file your annual report, the state will eventually “dissolve” your LLC. This can freeze your US bank accounts and stop your business in its tracks. We track these deadlines for you, ensuring your entity remains “Active and in Good Standing.”
Manage the UK Side with HMRC
Even though your LLC is in the USA, you are still a UK tax resident. This means the profits from your US business are generally taxable in the UK.
Because the US and the UK have a Double Taxation Treaty, you shouldn’t have to pay tax on the same dollar twice. However, the way you report this matters. If your US LLC is disregarded, HMRC usually views the income as yours personally. If you operate through a UK Limited Company that owns the US LLC, it becomes a corporate tax matter.
It is vital to keep your US and UK accounting synchronized. We provide integrated reporting so you can see your global profit and loss in one place, making your UK Self-Assessment or Corporation Tax returns much easier to manage.
Maintain Digital Bookkeeping Standards
The IRS doesn’t require a specific software, but they do require accurate records. Use cloud-based accounting tools like QuickBooks Online or Xero to track all income and expenses in real time. Separate your US and UK transactions, and maintain monthly reconciliations with your bank statements.
Keep all supporting documents for at least seven years: invoices, receipts, bank statements, and payment records. The IRS can audit you at any time, and having organized books makes the process far less painful.
