Specialist Amazon Seller Accountant: FBA Accounting, VAT & Tax Planning

UK-Based Amazon FBA Sellers

UK-based Amazon FBA sellers face a set of accounting challenges that compound with each other. Amazon's settlement reports must be reconciled against gross sales; not against the net payout received; to capture referral fees, FBA fulfilment charges, storage fees, advertising costs, and refund adjustments as individual expense categories rather than a single net deduction. VAT must be accounted for correctly on every UK sale, with the deemed supplier rules applied correctly for goods valued at £135 or below. And from April 2026, sole trader Amazon sellers with gross income above £50,000 must file quarterly MTD digital submissions in addition to their existing VAT MTD obligations.

We provide a complete Amazon FBA accounting service for UK-based sellers: monthly settlement reconciliation, quarterly VAT returns, annual accounts, Corporation Tax or Self-assessment, and year-round tax planning with everything correctly connected from platform data through to HMRC filings.

Overseas Amazon FBA Sellers with UK Marketplace Presence

For sellers based outside the UK whether in the EU, USA, UAE, China, or elsewhere: storing goods in Amazon's UK fulfilment centres triggers an immediate UK VAT registration obligation. The £90,000 VAT registration threshold that applies to UK-resident businesses does not apply to non-established taxable persons. You must register for UK VAT before your first UK sale, regardless of turnover. HMRC has significantly increased its data sharing with Amazon and other fulfilment platforms; failure to register results in backdated VAT assessments from the date of your first UK FBA shipment, plus penalties and the risk of account suspension.

We manage UK VAT registration for overseas Amazon sellers from anywhere in the world; preparing the application, managing HMRC correspondence, uploading your VAT number to Seller Central, configuring your MTD-compliant accounting software, and providing ongoing quarterly VAT returns that correctly reflect deemed supplier transactions and your own direct UK sales.

Amazon FBM Sellers

Fulfilled-by-Merchant sellers manage their own inventory and fulfilment but still face complex Amazon accounting obligations. Settlement reports must be reconciled to gross sales, referral fees deducted as an expense, and VAT accounted for on every sale at the correct rate. The deemed supplier rules apply differently for FBM sellers; Amazon does not act as deemed supplier for most FBM transactions, meaning VAT on those sales remains the seller's direct obligation. We ensure FBM sellers account correctly for the distinction between FBA and FBM transactions on their VAT returns.

Multichannel Sellers: Amazon and Beyond

Many Amazon sellers also operate on eBay, Etsy, Shopify, TikTok Shop, or their own branded storefront. Each channel has its own payout structure, its own fee model, and its own reporting to HMRC. For VAT, MTD, and income tax purposes, income is measured across all channels combined; not Amazon alone. We provide specialist multichannel accounting that consolidates your income from every platform, reconciles each channel's payout reports, and presents your complete financial position accurately across all sales sources.

Amazon Sellers Operating Through a Limited Company

Selling on Amazon through a limited company offers potential tax advantages for established sellers generating consistent profit; Corporation Tax on trading profit, flexibility in salary and dividend extraction, retained earnings within the company, and clear separation between business and personal finances. However, Amazon accounting for limited companies adds complexity beyond basic company accounts. The company's revenue must be correctly captured from settlement reports, Corporation Tax must be prepared with full inventory and COGS accounting, and the director's personal Self-assessment must reflect dividends and employment income correctly.

We provide complete Amazon accounting for limited companies; book-keeping, payroll, quarterly VAT returns, annual statutory accounts, Corporation Tax, and director Self-assessment; all prepared from correctly reconciled Amazon settlement data rather than from bank statements alone.

Amazon Sellers Scaling into European Marketplaces

Expanding from Amazon UK to Amazon Germany, France, Italy, Spain, or other EU marketplaces introduces cross-border VAT obligations that require specialist international knowledge. EU VAT registration in each country where goods are stored, OSS (One-Stop Shop) registration for distance sales above country-specific thresholds, IOSS for sub-€150 consignments shipped from outside the EU, and the EU's July 2026 flat-rate €3 customs duty per parcel for low-value IOSS shipments all create obligations that cannot be managed by a UK-only general accountant.

As cross-border VAT accountants for Amazon sellers, we advise on EU marketplace VAT strategy, manage OSS and IOSS registration and returns, ensure your Amazon Pan-European FBA stock movements are correctly accounted for from a VAT perspective, and keep your cross-border VAT position current as EU rules continue to evolve.

Your Gross Sales Are Higher Than Your Payout Suggests

Amazon reports your gross sales to HMRC under the OECD digital platform reporting rules: not your net payout. Since the first full-year platform reports were submitted by Amazon in January 2026 (covering all 2025 seller activity), HMRC can now directly compare the gross sales figure Amazon reports for your account against the income figure you declare on your Self-assessment or Corporation Tax return. If you have been booking only your net payout as income; without separately declaring the gross and deducting fees as expenses; your declared figure will not match Amazon's report. This discrepancy triggers an automated review.

A correctly prepared Amazon seller tax return reports gross sales as income and deducts Amazon referral fees, FBA fulfilment fees, FBA storage charges, advertising costs, and all other allowable Amazon charges as business expenses: arriving at the correct taxable profit while matching the gross figure Amazon has reported to HMRC.

Your VAT Position Is More Complex Than It Appears

Amazon operates as a deemed supplier for certain transactions on its marketplace: specifically, goods sold by non-UK businesses to UK customers where the consignment value is £135 or below, and goods sold by overseas businesses through Amazon regardless of value. In these cases, Amazon collects and remits the VAT directly, and the seller receives the full gross amount without any VAT component to account for on their own return. However, deemed supplier transactions must still be reported correctly on your VAT return: not as your own output VAT, but as exempt or out-of-scope supplies that reconcile against Amazon's own VAT accounting.

UK sellers who are VAT-registered must account for output VAT on their own direct UK sales, correctly identify deemed supplier transactions, and reclaim input VAT on FBA fees, advertising spend, and other Amazon charges. Getting the boundary between deemed supplier and non-deemed supplier transactions wrong; in either direction; produces a VAT return that will not reconcile against Amazon's VAT Transaction Report and creates exposure to HMRC assessment.

Your Inventory Position Directly Affects Your Profit

For Amazon FBA sellers, inventory is typically the largest balance sheet item and the biggest driver of actual profit. Correctly calculating cost of goods sold, accounting for the landed cost of imported stock (purchase price plus import duty plus freight plus Amazon inbound charges), valuing closing stock correctly at period end, and writing down obsolete or damaged inventory in a way HMRC accepts all require specialist knowledge that general bookkeeping does not provide.

Incorrect inventory accounting does not just produce wrong financial statements; it produces an incorrect tax liability. Overstating cost of goods sold reduces profit and understates tax. Understating it overstates profit and overpays tax. Failing to account for closing stock at all is one of the most common errors HMRC identifies in Amazon seller accounts.

Settlement Reports Are Not Straightforward Financial Records

Amazon releases settlement reports every two weeks, covering a period that typically crosses the end of one calendar month and the beginning of another. Each settlement includes current period sales, previous period adjustments, refund reversals, reserve movements, and promotional credits: some of which relate to sales from prior periods. Booking each settlement as income in the period it is received produces accounts that do not match your actual trading activity by month, misstate your VAT position in each quarter, and make it impossible to track your business performance accurately against a monthly plan.

We reconcile your Amazon settlements correctly; mapping gross sales, fees, refunds, and adjustments to the periods to which they relate, managing reserve movements separately from income, and producing clean monthly financial records that give you an accurate picture of your Amazon business performance month by month.

UK VAT Registration Threshold and the FBA Exception

UK-based Amazon sellers must register for VAT once their combined taxable turnover from all channels exceeds £90,000 in any rolling 12-month period. The threshold is measured on gross sales; not on Amazon payouts after fees, and not on profit. Amazon's settlement report gross sales figure is what counts, not the amount deposited in your bank. You have 30 days from the date you crossed the threshold to notify HMRC and begin collecting VAT. Late registration creates a backdated VAT liability from the registration date you should have met, plus a late registration penalty.

For overseas sellers including those based in the EU, USA, UAE, or China who are not established in the UK, the VAT registration threshold is zero. You must register for UK VAT before your first UK FBA shipment reaches Amazon's fulfilment centre. HMRC now shares data with Amazon and tracks FBA inbound shipments. Failure to register results in backdated VAT assessments covering every UK sale made since your first inbound shipment, plus interest and penalties, and can result in your Seller Central account being suspended until compliance is demonstrated.

The Deemed Supplier Rules: What Amazon Accounts for and What You Must

Since January 2021, Amazon has operated as a deemed supplier for specific transactions on its marketplace. Understanding these rules correctly is essential for UK Amazon sellers because applying them incorrectly produces VAT returns that do not reconcile with Amazon's VAT Transaction Report which HMRC can access.

Amazon is the deemed supplier and therefore accounts for the VAT in the following situations:

Goods sold by non-UK businesses to UK customers through Amazon, where the goods are already in the UK at the point of sale (regardless of consignment value).

Goods imported into the UK for sale through Amazon, where the consignment value is £135 or below (including goods from UK-based overseas-registered sellers).

Amazon is NOT the deemed supplier in these situations:

Goods sold by UK-established businesses from UK stock to UK customers: these are standard taxable supplies and VAT is the seller's direct obligation.

Goods above £135 imported into the UK from outside the UK: import VAT applies at the border, and the seller accounts for UK output VAT on the subsequent sale.

Correctly identifying which of your Amazon transactions are deemed supplier transactions and which are your own direct VAT supplies is the foundation of a compliant Amazon VAT return. We map your Amazon VAT Transaction Report against each category, reconcile output VAT correctly, and ensure your input VAT claims on FBA fees, advertising, and other Amazon charges are applied to the right transactions.

Postponed VAT Accounting on Imports

Amazon FBA sellers who import goods from outside the UK: whether from China, India, the USA, or anywhere else can use Postponed VAT Accounting (PVA) to defer the VAT due on importation, accounting for it on their VAT return rather than paying it at the border. PVA provides a significant cashflow advantage for sellers importing large volumes of stock. However, PVA import VAT must be correctly entered as both output and input VAT on the same return, and the PVA statements from HMRC must be downloaded monthly and reconciled against import records.

We manage PVA accounting for Amazon FBA sellers, ensuring that import VAT is correctly declared on each quarterly return, PVA statements are downloaded and reconciled monthly, and the net VAT position on imports reflects the correct offsetting of output and input PVA in each period.

Making Tax Digital for VAT and Income Tax

MTD for VAT has been mandatory for all VAT-registered businesses since April 2022. For Amazon sellers, this means VAT returns cannot be prepared from manually entered figures; sales data must be maintained in MTD-compatible digital records, and returns must be filed through HMRC-approved software. Amazon settlement data must feed into your accounting software digitally; manual re-entry of settlement figures is not MTD-compliant.

From April 2026, sole trader Amazon sellers with gross income above £50,000 across all channels must also file quarterly MTD Income Tax submissions in addition to their VAT MTD obligations. Many growing Amazon sellers are now facing MTD obligations on two fronts simultaneously. We assess your full MTD position, configure your cloud accounting software with the correct Amazon integrations, and manage both VAT and Income Tax MTD submissions on your behalf.

Amazon EU VAT and Cross-Border Compliance

Expanding into Amazon's European marketplaces: Germany, France, Italy, Spain, Netherlands, Sweden, Poland, and others; introduces EU VAT obligations that require country-specific registration or OSS enrolment. Amazon's Pan-European FBA programme moves stock between EU fulfilment centres automatically to optimise delivery times which means your goods may be stored, and your sales fulfilled, in multiple EU countries simultaneously, creating VAT registration obligations in each.

We advise Amazon sellers on the EU VAT obligations generated by European marketplace expansion, manage OSS registration and quarterly returns for distance sales above country thresholds, advise on IOSS for sub-€150 consignments shipped from outside the EU, and calculate the impact of the July 2026 EU flat-rate €3 customs duty on your pricing model and landed cost for European customers.

Amazon FBA Book-keeping: Settlement Reconciliation Every Month

Amazon settlement reports are the most misunderstood financial document in ecommerce accounting. Each report nets off gross sales, referral fees, FBA fulfilment charges, storage fees, advertising debits, refund adjustments, promotional credits, reserve movements, and any other platform charges into a single disbursement figure. Without reconciling that figure back to its gross components, your accounts will be wrong in every metric that matters; gross revenue, gross margin, VAT, taxable profit, and cost of goods sold.

We reconcile your Amazon settlement reports every month; mapping gross sales, fee categories, refunds, advertising charges, and reserve movements to the correct accounting periods, maintaining separate cost categories for each type of Amazon charge, recording inventory purchases and cost of goods sold at landed cost, and producing monthly management accounts that show your true revenue, true gross margin, and true cash position by product category and in total. We work across Xero, QuickBooks, FreeAgent, and Sage, integrating directly with Amazon Seller Central through compatible data tools to minimise manual processing.

Best for: All Amazon FBA and FBM sellers from sole traders approaching the VAT threshold to limited companies with established Amazon businesses and high monthly settlement volumes.

Amazon VAT Registration, Returns & Deemed Supplier Compliance

We provide a complete Amazon VAT service: UK VAT registration for UK and overseas sellers, quarterly VAT returns that correctly apply the deemed supplier rules, reconciliation of your VAT Transaction Report against your returns, PVA accounting for imported stock, input VAT claims on FBA fees and Amazon advertising, and management of any HMRC VAT correspondence. We monitor your gross sales in real time and advise on VAT registration timing before you are required to file, ensuring you are never caught by a late registration assessment.

For overseas sellers registering for UK VAT, we manage the full registration process remotely: preparing the application, managing the application reference number requirement that HMRC introduced for new VAT applicants, uploading your VAT number to Seller Central within Amazon's 90-day window, configuring your MTD-compliant accounting software, and providing ongoing quarterly returns from your first VAT period.

Best for: All VAT-registered Amazon sellers (UK and overseas), those approaching the £90,000 threshold, overseas FBA sellers registering for UK VAT for the first time, and Amazon sellers whose current VAT returns do not reconcile cleanly against their VAT Transaction Reports.

Amazon FBA Tax Accountant: Self-Assessment & Corporation Tax for Amazon Sellers

Amazon sellers operating as sole traders must file an annual Self-assessment return reporting gross Amazon sales as trading income, deducting all allowable business expenses including Amazon fees, cost of goods sold, import duties, advertising, and professional fees and arriving at the correct taxable profit. From April 2026, sole traders with gross income above £50,000 file quarterly MTD Income Tax submissions rather than a single annual return.

Amazon sellers operating through a limited company must file annual statutory accounts, a Corporation Tax return with full inventory and COGS accounting, and the director's personal Self-assessment reflecting dividends and employment income. We prepare both the company and personal returns from correctly reconciled settlement data ensuring every figure in your tax return is consistent with what Amazon has reported to HMRC.

Best for: Sole trader Amazon sellers filing Self-assessment, limited company Amazon sellers requiring annual accounts and Corporation Tax, and sellers approaching the MTD for Income Tax threshold from April 2026.

Amazon FBA Inventory Accounting: Landed Cost, COGS & Stock Valuation

For Amazon FBA sellers, inventory accounting is the single biggest driver of reported profit and taxable income. We calculate cost of goods sold using the landed cost method, purchase price plus import duty plus international freight plus Amazon inbound charges and reconcile closing stock quantities against Amazon FBA inventory reports at each period end. We account for lost or damaged inventory through Amazon's reimbursement scheme, write down obsolete or slow-moving stock where the net realisable value is below cost, and ensure your stock valuation is HMRC-compliant and defensible.

Correct inventory accounting eliminates two of the most expensive errors Amazon sellers make with their tax returns: overstating COGS (which understates profit and understates tax, creating a potential HMRC assessment) and understating COGS (which overstates profit and overpays tax unnecessarily). We produce a monthly COGS statement alongside your management accounts so you always know your true gross margin by product and category.

Best for: All product-based Amazon FBA sellers, private label sellers with high stock value and complex import structures, and Amazon businesses where the owner is uncertain whether current inventory accounting is producing the correct taxable profit figure.

Cross-Border VAT for Amazon Sellers: EU Marketplace VAT, OSS, IOSS & Pan-European FBA

Expanding into Amazon's European marketplaces generates EU VAT obligations that sit entirely outside UK VAT compliance. Pan-European FBA automatically distributes your inventory across fulfilment centres in Germany, France, Italy, Spain, Poland, Sweden, and other EU countries; creating VAT registration obligations in each country where your stock is stored and sold locally. Without specialist cross-border VAT support, Amazon's Pan-European programme creates as many compliance problems as it solves in operational efficiency.

We advise on the EU VAT strategy that is right for your expansion plan; country-specific VAT registrations where Pan-European FBA storage triggers direct registration obligations, OSS enrolment for distance sales above the EU-wide €10,000 threshold for B2C sales to EU consumers, IOSS for sub-€150 consignments shipped from outside the EU, and the impact of the July 2026 EU customs duty changes on your pricing model. We manage ongoing EU VAT returns in each relevant jurisdiction or OSS quarterly submissions, ensuring your cross-border expansion is tax-efficient and fully compliant.

Best for: Amazon sellers expanding to European marketplaces, those using Pan-European FBA or European Fulfilment Network, and UK sellers shipping directly to EU customers whose current EU VAT position has not been reviewed by a specialist.

MTD Compliance: VAT and Income Tax for Amazon Businesses

MTD for VAT requires your Amazon sales data to feed into MTD-compatible accounting software digitally, manual re-entry is not compliant. We configure your accounting software with the correct Amazon integration, ensuring settlement data flows into your digital records automatically, VAT returns are generated from complete digital records, and submissions are made to HMRC through an MTD-approved software path.

From April 2026, sole trader Amazon sellers with gross income above £50,000 across all channels must also file quarterly Making Tax Digital Income Tax updates. Many Amazon sellers are now facing dual MTD obligations; VAT MTD already in force, and Income Tax MTD arriving in April 2026. We assess your complete MTD position, establish the correct software setup for both obligations, and manage your quarterly submissions and year-end declaration on your behalf so you are fully compliant before any deadline.

Best for: All VAT-registered Amazon sellers (MTD for VAT), sole trader Amazon sellers approaching or above £50,000 gross income (MTD for Income Tax from April 2026), and any Amazon seller whose current VAT returns are not being filed through an MTD-compliant digital process.

Amazon Ecommerce Tax Planning: Structure, Extraction & Growth Strategy

Effective tax planning for Amazon sellers goes beyond choosing the right business structure. We review your complete financial position; trading profit after correctly reconciled COGS and fees, retained earnings within your limited company, the optimal salary and dividend split for owner-directors, pension contributions through the company, the timing of major inventory purchases to manage taxable profit across accounting periods, and the long-term ownership structure for an Amazon business that may be sold or acquired.

For sole traders approaching the point where a limited company becomes more tax-efficient, we model the after-tax position in each structure using your actual settlement data, not a theoretical income figure, before making any recommendation. For established Amazon businesses operating through a limited company, we review Corporation Tax efficiency, the treatment of stock as a balance sheet asset versus an expense, and the tax implications of scaling into new categories or international marketplaces.

Best for: Amazon sellers approaching £40,000 to £50,000 in annual profit considering limited company structure, established FBA businesses with significant retained earnings, and sellers planning exit or acquisition and wanting to understand the tax implications in advance.

Setting Up Your Amazon Business Correctly from Day One

The financial decisions made when setting up an Amazon selling business have consequences that persist for years. Business structure, VAT registration timing, accounting software selection and Amazon integration, import cost accounting from the first inbound shipment, and the correct treatment of pre-launch costs and initial stock purchases all require specialist input at the outset, not after the first year's accounts have been prepared incorrectly.

We provide an Amazon seller onboarding service for new and early-stage sellers, advising on sole trader versus limited company structure for your projected income level, managing VAT registration where required, configuring Xero, QuickBooks, or FreeAgent with the correct Amazon integration, establishing a COGS tracking system from the first inventory purchase, and preparing a financial forecast for your first 12 months of Amazon trading. Getting the setup right from day one is the most cost-effective investment a new Amazon seller can make.

Best for: New Amazon sellers before or during their first year of trading, overseas sellers entering the UK marketplace for the first time, and sellers who have been trading for one or two years but have never had their accounting setup professionally reviewed.
