Understand the “Nexus” Trigger Before You Choose
Before comparing states, you must understand why you are registering. In the US, you only register for sales tax in states where you have “nexus”, a significant connection.
- Physical Nexus: Having an office, employees, or inventory in a state. If you use Amazon FBA or a 3PL (Third-Party Logistics) provider, you likely have physical nexus in every state where your goods are stored.
- Economic Nexus: Reaching a specific sales threshold (typically $100,000 in sales or 200 transactions, though many states are now removing the transaction count requirement in 2026).
Register only where required. Don’t volunteer for taxes you don’t owe. However, if you have a choice of where to house your inventory or where to focus your marketing, the following comparisons will help you strategize.
The “NOMAD” States: Zero Sales Tax
If your goal is to minimize the tax burden on your customers and simplify your life, the “NOMAD” states are the gold standard. These five states do not have a general state-level sales tax:
- New Hampshire
- Oregon
- Montana
- Alaska (Note: Some local municipalities in Alaska do charge sales tax, though there is no state-level tax).
- Delaware
The Benefit: If you base your operations or warehouse in Delaware, you don’t have to worry about collecting sales tax on items shipped from that location to other no-tax states. It also makes your pricing more competitive for local customers.
The Strategy: Many international sellers choose to incorporate their US LLC in Delaware for its business-friendly laws, but remember: you still have to collect sales tax in other states if you ship goods to customers there and meet their nexus thresholds.
Best States for Simplicity and Low Rates
For many businesses, the nightmare isn’t the tax rate itself, it’s the calculation. Some states have a single flat rate, while others allow every tiny town to add its own “local” tax on top of the state rate.
1. Kentucky (The Simplicity Leader)
Kentucky remains a favorite for international sellers. It features a flat 6% sales tax rate across the entire state. There are no local jurisdictions, no city taxes, and no county add-ons.
- Why it works: You always know the rate. Whether you sell to someone in Louisville or a rural farm, it’s 6%. This makes your bookkeeping and tax calculations incredibly straightforward.
2. New Jersey
New Jersey offers a flat 6.625% state rate. Similar to Kentucky, there are no local sales taxes.
- Why it works: It’s a major logistics hub. If your goods enter through the Port of New York and New Jersey, registering here is often a necessity. The lack of local complexity is a massive relief for your compliance team.
3. Michigan
Michigan holds a steady 6% rate with no local sales taxes.
- Why it works: It provides a predictable environment for businesses looking to scale in the Midwest without getting bogged down in municipal filings.
The “Home Rule” States: Proceed with Caution
If you are looking for ease of compliance, you should generally avoid focusing your physical presence in “Home Rule” states unless your market data demands it. In these states, local cities and counties administer their own taxes, often requiring separate registrations and filings.
- Colorado: Rates can fluctuate from 2.9% to over 11% depending on the specific street address.
- Alabama: Known for complex local requirements that can make manual filing nearly impossible for a small team.
- Louisiana: Extremely fragmented local tax authorities.
The Sterlinx Advice: If you have economic nexus in these states, you must register. However, if you are choosing where to set up your first US warehouse, these states will significantly increase your administrative costs.

The Impact on International Sellers
For a non-US resident, US sales tax registration is not just about the money; it’s about the documentation. To register, you will generally need:
- An EIN (Employer Identification Number) from the IRS.
- A US business address (virtual offices often work).
- A breakdown of your sales by state.
Don’t worry about the lack of a Social Security Number (SSN). While many state forms ask for one, most states have alternative procedures for international owners. This is where having a partner like Sterlinx Global becomes essential. We bridge the gap between US regulatory requirements and your international reality.
Managing Finances Across Borders
Choosing a state is only half the battle. You must also manage the currency exchange and the movement of funds to pay these tax authorities. Many sellers lose 3-5% of their margin simply on poor exchange rates when paying their US tax bills. We recommend exploring cross-border currency management to protect your profits.

TITLE: UK Update (HMRC): 2026 Reporting and Compliance Changes for Online Sellers
The landscape of UK ecommerce has shifted permanently. If you are selling on platforms like Amazon, eBay, Etsy, or Vinted, the days of “flying under the radar” are officially over. As of early 2026, the tax transparency between digital platforms and HM Revenue & Customs (HMRC) has reached an unprecedented level.
For many business owners, these updates might feel overwhelming. However, understanding these changes is the first step toward building a sustainable, compliant, and scalable brand. At Sterlinx Global, we operate as your end-to-end compliance suite, ensuring that as HMRC evolves, your business stays ahead of the curve without the manual headache of tax calculations and filings.
Here is everything you need to know about the 2026 HMRC updates and how they impact your daily operations.
The First Major Milestone: The January 2026 Data Dump
We have just passed a significant turning point. On January 31, 2026, major digital marketplaces submitted their first full year of seller data for the 2025 calendar year directly to HMRC. This move is part of the OECD’s model reporting rules, and it changes the fundamental relationship between sellers and the tax office.
What HMRC Now Knows
In previous years, HMRC relied largely on your self-reported figures. Now, they receive automated reports containing:
- Your Gross Sales Proceeds: Exactly how much money passed through the platform.
- Transaction Counts: How many items you sold.
- Platform Fees: Deductions made by the marketplace.
- Seller Identification: Your linked bank accounts and personal details.
This means HMRC can now cross-check your Self Assessment tax returns against third-party data instantly. If there is a discrepancy between what eBay says you earned and what you reported, an automated red flag is likely to follow. Don’t worry: this doesn’t mean you are in trouble if you have been honest; it simply means your record-keeping must be impeccable to explain any differences in fees or returns.
Making Tax Digital (MTD) for Income Tax: The Quarterly Shift
The most significant operational change in 2026 is the rollout of Making Tax Digital for Income Tax Self Assessment (MTD ITSA). For years, ecommerce sellers have operated on an annual cycle: calculating profits once a year and filing by January 31. That era is ending.
Quarterly Reporting is the New Standard
If your gross income (turnover) exceeds £50,000, you are now required to:
- Maintain Digital Records: Paper ledgers or unlinked spreadsheets are no longer sufficient. You must use functional compatible software to track every sale and expense.
- Submit Quarterly Updates: Every three months, you must send HMRC a summary of your business income and expenses. This provides HMRC with a real-time view of your tax liability.
- Final Declaration: At the end of the tax year, you submit a final declaration to confirm your total figures.
It’s About Turnover, Not Profit
A common misconception is that if your profit is low, you don’t need to worry about MTD. This is incorrect. The requirement is based on your gross income. If you sell £55,000 worth of goods but your profit is only £10,000 after costs, you are still legally required to join the MTD scheme.
Managing this volume of data every quarter can be exhausting for a solo founder. This is why we focus on advanced financial forecasting and automated compliance: to ensure you never miss a quarterly window.
Stricter VAT Enforcement and the ‘0990’ Reference
VAT compliance has also seen a tightening of the screws. HMRC has introduced new security measures for businesses registering for VAT or changing their legal structure.
The 0990 Application Reference
New VAT applicants now often require a specific application reference number (‘0990’) to complete their registration. HMRC is using this to filter out fraudulent applications and ensure that “deemed supplier” rules are being followed correctly. If you are an overseas seller or a UK business using marketplaces, the marketplace is often responsible for collecting and remitting VAT, but you still have strict reporting obligations.
Failing to apply the correct VAT rate can result in heavy penalties. By using a global compliance suite like Sterlinx Global, you ensure that your VAT filings in the UK and across the EU are handled with precision, reflecting the latest 2026 regulatory standards.
The Trading Allowance: Who Is Exempt?
Not every casual seller needs to register as a business. HMRC maintains the £1,000 Trading Allowance.
- Under £1,000: If your total gross income from all “side hustles” or ecommerce activities is less than £1,000 in a tax year, you generally do not need to report it.
- Over £1,000: The moment you cross this threshold, you must register for Self Assessment and keep detailed records of sales, platform fees, and inventory costs.
Even if you are just starting out, keeping professional records from day one is essential. It makes the transition to a Limited Company or VAT registration much smoother as you grow.
Looking Ahead: The 2029 E-Invoicing Roadmap
While 2026 is the year of data sharing and quarterly reporting, HMRC has already signaled the next big shift. The UK government has set a target for mandatory e-invoicing to begin in 2029.
By 2026, we expect further guidance on the technical standards for these invoices. E-invoicing will mean that invoices are sent directly from your system to your customer’s system (and potentially HMRC) in a structured data format. This will eliminate manual data entry and further reduce the “tax gap.” Getting your digital records in order today for MTD is the best way to future-proof your business for the e-invoicing mandate of the near future.

FAQ: HMRC 2026 Ecommerce Updates
What are the new HMRC rules for online sellers in 2026?
The 2026 updates focus on automated data sharing from platforms like Amazon and eBay directly to HMRC, and the mandatory start of Making Tax Digital (MTD) for Income Tax, which requires quarterly reporting for those over specific income thresholds.
Does Etsy report to HMRC 2026?
Yes. Since January 2024, Etsy has been required to collect data on UK sellers. By January 31, 2026, Etsy submitted a comprehensive report of all 2025 seller transactions to HMRC.

Why Structure and Compliance are Your Best Growth Tools
Accounting is more than just a legal requirement; it is the heartbeat of your business. Accurate records allow you to see exactly where your money is going and where your next investment should be. In 2026, HMRC’s “Making Tax Digital” initiatives are more integrated than ever, meaning manual errors are easier for authorities to spot.
By maintaining high standards in your accounting services for small business uk, you protect your company from unnecessary audits and build a financial history that makes your business attractive to lenders and investors.
Master Your Accounting Calendar: Key 2026 Deadlines
Missing a deadline is the fastest way to lose money through automatic penalties. In 2026, the timelines remain strict. Your specific deadlines depend on your “Accounting Reference Date” (usually the anniversary of your company’s incorporation).
1. Annual Accounts (Companies House)
You must file your statutory accounts with Companies House 9 months after your financial year-end. For example, if your year-end was 31 December 2025, your deadline is 30 September 2026.
2. Corporation Tax Payment
Surprisingly, the payment is due before the tax return. You must pay your Corporation Tax bill 9 months and 1 day after your accounting period ends. Do not wait until you file your return to pay, or you will face interest charges.
3. Company Tax Return (CT600)
The formal return (CT600) must be submitted to HMRC 12 months after your accounting period end.
4. Confirmation Statement
This is a separate filing that confirms your company’s details (directors, shareholders, and registered office) are correct. It is due every 12 months, within 14 days of your review period end.
Organize Your Records Like a Pro
To ensure a smooth year-end, you must maintain a “paper trail” for every single transaction. In 2026, digital record-keeping is the gold standard.
- Income Records: Track every sale, including those near the end of your financial year.
- Expense Receipts: Keep invoices for everything: from software subscriptions and professional fees to travel and home office equipment.
- Bank Reconciliations: Regularly match your bank statements to your accounting software. This ensures no transaction is missed or duplicated.
- Asset Schedules: Maintain a list of physical assets like machinery or high-end tech equipment, as these are treated differently for tax purposes.
Decoding Statutory Accounts: What You Must Prepare
When we prepare your year-end accounts, they must follow UK accounting standards. Your statutory accounts typically include:
- The Balance Sheet: A snapshot of what the company owns and owes at the end of the financial year. A director must sign this to confirm its accuracy.
- Profit and Loss (P&L) Account: This shows your sales, running costs, and the profit (or loss) the company made during the period.
- Notes to the Accounts: These provide vital context, such as the accounting policies used and details about directors’ remuneration.
While small and micro-entities can file “abridged” or simplified accounts publicly at Companies House, full accounts are always required for HMRC.
Corporation Tax in 2026: Rates and Reliefs
For 2026, the UK Corporation Tax system uses a tiered approach based on your profitability.
| Profit Level |
Tax Rate |
| Profits up to £50,000 |
19% (Small Profits Rate) |
| Profits over £250,000 |
25% (Main Rate) |
| Profits between £50,001 and £250,000 |
Tapered rate with Marginal Relief |
Don’t worry about the math behind Marginal Relief; our team handles these complex calculations for you.
Leveraging Capital Allowances
You can reduce your tax bill by claiming capital allowances on assets you buy for business use. In 2026, the Annual Investment Allowance (AIA) allows most small businesses to deduct the full value of qualifying plant and machinery (up to £1 million) from their profits before tax. This is a powerful tool for businesses investing in new technology or equipment.
Beyond the Year-End: VAT and Payroll
UK limited company accounting isn’t just an annual event; it’s a monthly and quarterly commitment.
VAT Compliance
If your taxable turnover exceeds £90,000 (current threshold for 2026), you must register for VAT. You will then need to file VAT returns: usually every three months: and pay any VAT due to HMRC.
Payroll (PAYE)
If you pay yourself a salary or employ staff, you must operate a PAYE (Pay As You Earn) system. This involves reporting pay and deductions to HMRC in real-time (RTI) whenever you pay your employees.
Avoid the Trap: Penalties and Common Mistakes
HMRC and Companies House are automated. If you are late, the system generates a penalty automatically.
- Late Accounts: Penalties start at £150 for being one day late and can escalate to £1,500 if you are more than six months late.
- Late Tax Returns: A £100 penalty applies even if you have no tax to pay.
- Incorrect Information: Filing accounts with errors can lead to “back-dated” tax bills and interest charges.
This is why having a structured partner is essential. We don’t just “advise”: we execute. We take your data and transform it into compliant filings so you can sleep soundly at night.

Seven Critical Accounting Mistakes Amazon Sellers Make (And How to Fix Them Today)
Selling on Amazon is one of the fastest ways to scale a global brand. Whether you are moving units in the UK, expanding into the USA, or navigating the complexities of the European Union, the marketplace provides the infrastructure to grow at lightning speed. However, as your sales volume increases, so does the complexity of your back-office operations.
Many sellers find that while their Seller Central dashboard shows record-breaking revenue, their bank accounts don’t seem to reflect that success. This discrepancy often boils down to accounting errors. Traditional accounting methods rarely work for the high-frequency, high-data world of Amazon.
At Sterlinx Global Ltd, we see these patterns daily. We operate as a Global Tax Compliance Suite, helping businesses across the UK, USA, Canada, and Australia manage their full-suite compliance while handling VAT registrations across the EU. We’ve identified seven critical mistakes that could be hurting your bottom line and, more importantly, how you can fix them today.
1. Recording Net Payouts Instead of Gross Sales
This is the single most common mistake Amazon sellers make. Every two weeks, Amazon deposits a “settlement” into your bank account. It is incredibly tempting to simply record this amount as your “Sales” in your accounting software.
The Mistake: That deposit is a net figure. It is your gross sales minus Amazon’s referral fees, FBA storage fees, advertising costs, refunds, and sometimes even sales tax or VAT. If you only record the net amount, you are under-reporting your true revenue and failing to track your actual expenses.
The Fix: You must record the gross sales amount and then list each Amazon fee as a separate expense line. This ensures your books match the 1099-K (in the US) or your VAT reports (in the UK/EU).
Benefit: Doing this allows you to see exactly where your money is going. It also ensures you are claiming every tax-deductible expense possible, lowering your overall tax liability.
2. Misclassifying Inventory as an Immediate Expense
When you spend £10,000 on a new shipment of stock, it feels like a massive expense. Naturally, many sellers record this full amount as an expense the moment the invoice is paid.
The Mistake: Inventory is an asset, not an expense: at least until it sells. If you buy a year’s worth of stock in November and “expense” it all immediately, your November reports will show a massive loss, while your December reports will show an artificially high profit. This “seesaw” effect makes it impossible to understand your actual monthly performance.
The Fix: Record inventory purchases on your Balance Sheet as an asset. As items are sold, move the corresponding cost to your Profit & Loss statement as “Cost of Goods Sold” (COGS).
Benefit: This provides a clear view of your gross margins and ensures you are only paying taxes on the profit you’ve actually realized during that period.
3. Ignoring the “Settlement Period” Timing Gap
Amazon doesn’t pay you on the first and last day of the month. Their 14-day settlement cycles often bridge two different months: for example, a payout might cover sales from June 24th to July 7th.
The Mistake: If you record the entire payout in July because that’s when the cash hit your bank, your June sales will look lower than they actually were, and July will look inflated. This is known as “Cash Basis” accounting, and for a high-volume Amazon business, it is incredibly misleading.
The Fix: Switch to Accrual Accounting. This means you record the revenue on the day the customer bought the product, regardless of when Amazon actually transfers the funds to you.
Reassuring Fact: Don’t worry if this sounds complex. Modern e-commerce accounting tools and services like Sterlinx Global can automate this mapping for you, ensuring your data is synchronized perfectly with the calendar months.
4. Forgetting “Landed Costs” in Your COGS
What does your product actually cost? If you only count the price you paid the manufacturer, you are missing a huge part of the puzzle.
The Mistake: Many sellers fail to include shipping, customs duties, insurance, and prep-center fees into their Cost of Goods Sold. These “landed costs” can easily eat up 10-20% of your margin. If you don’t track them, you might be selling products at a loss without even realizing it.
The Fix: Calculate a “Landed Cost” for every SKU.
- Formula: (Unit Cost + Freight + Customs/Duties + Packaging) / Number of Units.
Actionable Step: Review your shipping invoices from the last quarter and update your COGS templates. This ensures your profit margins are grounded in reality.
5. Mixing Personal and Business Expenses
It starts small: a software subscription here, a shipping supply purchase there, all on your personal credit card. Or perhaps you use the business account to pay for a personal dinner.
The Mistake: Mixing funds creates a “commingling” of assets. Not only does this make your bookkeeping a nightmare, but it can also “pierce the corporate veil,” potentially making you personally liable for business debts or legal issues. Furthermore, it makes an audit from HMRC or the IRS much more stressful and expensive.
The Fix: Maintain strictly separate bank accounts and credit cards for your Amazon business. If you must use personal funds, record it as a formal “Director’s Loan” or “Owner’s Investment” and reimburse yourself through a documented transaction.
Benefit: Clean books mean faster year-end filing and a much higher valuation if you ever decide to sell your brand.
6. Overlooking VAT on Amazon Reimbursements
Amazon isn’t perfect. They lose inventory, and they damage items in the warehouse. When they do, they reimburse you.
The Mistake: Many sellers treat these reimbursements as “other income” and forget that, in jurisdictions like the UK or Germany, these payments may have VAT implications. Depending on how the reimbursement is structured, you may need to account for output VAT, or it may be a VAT-neutral adjustment. Ignoring this can lead to discrepancies in your European VAT filings.
The Fix: Ensure your accounting workflow identifies “Reimbursement” lines in your Amazon settlement reports. Treat them according to the specific tax rules of the marketplace country.
How we help: At Sterlinx Global, we specialize in these nuances. We don’t just look at the big numbers; we dive into the line-item data to ensure your VAT and Sales Tax filings are 100% compliant.
7. Falling Behind on Global Tax Nexus
As you grow, you might start using Amazon’s FBA programs in the US (using multiple warehouses) or the Pan-EU FBA program in Europe.
The Mistake: Storing inventory in a new state or country often triggers a “Nexus” or a VAT registration requirement. Many sellers wait until the end of the year to check their tax obligations, only to find they should have been collecting and remitting tax in six different countries for months.
The Fix: Be proactive. Before turning on international shipping or multi-country warehousing, consult with a compliance partner. If you are expanding into new territories, register for services in those jurisdictions immediately.

Running a UK Limited Company: Seven Critical Tax Filing Mistakes to Avoid
Running a UK Limited Company comes with a specific set of administrative hurdles. Whether you are a local entrepreneur or an international seller who utilized company formation for non-UK residents, the responsibility of Corporation Tax compliance sits squarely on your shoulders.
As of March 2026, HMRC has increased its focus on digital record-keeping and data cross-referencing. For ecommerce brands and fast-growing SMEs, a single oversight in your CT600 (Corporation Tax Return) can lead to more than just a slap on the wrist, it can result in significant financial penalties and unnecessary tax bills.
At Sterlinx Global Ltd, we see these errors daily. Here are the seven most common mistakes directors make with their UK tax filings and, more importantly, how you can fix them before the deadline hits.
1. Confusing the Filing Deadline with the Payment Deadline
This is the “silent killer” for many new business owners. In the UK, the timeline for your accounts and your tax return does not always follow a simple logic.
- The Mistake: Many directors assume they have 12 months to pay their tax because they have 12 months to file their CT600 return.
- The Reality: For most companies with taxable profits up to £1.5 million, the deadline to pay your Corporation Tax is usually 9 months and 1 day after the end of your accounting period. However, the deadline to file your CT600 is 12 months after the end of that period.
The Fix: Set two separate calendar alerts. If your year-end is 31st December, your payment is due by 1st October the following year, even if you don’t submit the paperwork until December. Paying late triggers automatic interest charges from HMRC, even if it was an honest mistake.
2. Incorrect Accounting Period Dates (Especially in Year One)
If you have just started your journey, your first “year” of trading rarely fits into a neat 12-month window.
- The Mistake: Entering the wrong start or end dates on your CT600. This is common when a company’s first accounting period is longer than 12 months (which happens often when you register a company and choose a specific year-end).
- The Reality: A Corporation Tax return cannot cover a period longer than 12 months. If your first set of accounts covers 13 months, you actually need to file two separate tax returns: one for the first 12 months and one for the remaining month.
The Fix: Check your Accounting Reference Date (ARD) on Companies House. Before you start your filing, verify the exact dates HMRC expects. This is why we recommend using UK tax tips to run your business accounting to ensure your internal records match the official registry.
3. Treating Depreciation as a Tax-Deductible Expense
In your profit and loss statement, depreciation is a standard accounting entry to show how your assets (like laptops or machinery) lose value over time.
- The Mistake: Assuming that because depreciation reduces your “accounting profit,” it also reduces your “taxable profit.”
- The Reality: HMRC does not allow depreciation as a tax-deductible expense. Instead, they use a system called Capital Allowances.
The Fix: You must “add back” depreciation to your profit and then claim Capital Allowances instead. In 2026, the Annual Investment Allowance (AIA) remains a powerful tool, allowing most businesses to claim 100% of the cost of qualifying plant and machinery (up to £1 million) in the year of purchase. If you bought £5,000 worth of hardware for your ecommerce operations, make sure you claim the AIA to wipe that cost off your taxable profit immediately.
4. Including Non-Deductible “Business” Expenses
It is a common misconception that if a company pays for something, it is automatically a business expense.
- The Mistake: Claiming for client entertainment, personal travel, or regulatory fines.
- The Reality: HMRC is very strict. “Business entertaining” (taking a client to lunch) is almost never tax-deductible. Neither are parking fines or certain legal costs related to capital structures.
- Ecommerce Impact: For sellers, this often extends to personal subscriptions that aren’t “wholly and exclusively” for the business.
The Fix: Separate your expenses into “allowable” and “disallowable” categories in your bookkeeping software (like Xero or QuickBooks) throughout the year. When we handle your compliance at Sterlinx Global, we automatically filter these out to ensure your CT600 is compliant and doesn’t trigger an HMRC enquiry.
5. Failing to Report Global Income or “Other” Revenue
For businesses involved in Amazon Pan-European VAT or international sales, income streams can get messy.
- The Mistake: Only reporting UK-based sales or forgetting about secondary income like bank interest, rental income from company property, or profit from the sale of assets (Capital Gains).
- The Reality: A UK Limited Company is taxed on its worldwide profits. Even if the money stays in a foreign currency account or a digital wallet like Wise or Payoneer, it must be reported.
The Fix: Perform a full bank reconciliation across all platforms. Ensure your “Total Income” figure includes every penny the company received, regardless of where the customer was located or which currency they paid in.
6. Poor Record-Keeping and “The Shoebox Method”
In the age of Making Tax Digital (MTD), the “shoebox full of receipts” is not just inefficient, it’s a compliance risk.
- The Mistake: Relying on manual spreadsheets or waiting until the end of the year to “sort out the books.”
- The Reality: Disorganised records lead to duplicate entries, missing VAT reclaim opportunities, and incorrect opening balances. If your opening balance doesn’t match the closing balance of the previous year, HMRC’s systems will flag your return for review.
The Fix: Move to a cloud-based accounting system immediately. Link your business bank feeds so transactions are pulled in daily. At Sterlinx Global, we function as your data-driven compliance partner; you provide the digital data, and we ensure the bookkeeping is tax-ready every single day.
7. Submitting Without an iXBRL Format Review
HMRC requires all company tax returns and accounts to be submitted in a specific digital language called iXBRL (Inline eXtensible Business Reporting Language).
- The Mistake: Trying to upload a standard PDF or a Word document of your accounts to the HMRC portal.
- The Reality: HMRC’s software will reject non-iXBRL files. Furthermore, if the “tags” in the iXBRL file are incorrect, your tax calculations might be misinterpreted by HMRC’s automated systems.
The Fix: Don’t DIY your filing if you aren’t using professional tax software. Most “off-the-shelf” consumer tools are fine for basic bookkeeping, but for Corporation Tax compliance, you need software that generates certified iXBRL output. A single tagging error can delay your filing or trigger an HMRC query.
