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

Amazon accounting is nothing like standard business bookkeeping. Settlement reports net off referral fees, FBA fees, advertising credits, refunds, and storage charges before depositing a single figure into your bank account. That figure bears almost no resemblance to your gross sales, your VAT liability, or your taxable profit. A general accountant who works from your bank statement is working from the wrong number; and HMRC, which now receives detailed Amazon transaction data through platform reporting obligations, will know it.

Consultax Chartered Accountant is a specialist Amazon seller accountant for FBA, FBM, and multichannel UK sellers. We reconcile your settlement reports correctly, manage your VAT under the deemed supplier rules, prepare your quarterly MTD submissions, and handle your annual accounts and Corporation Tax or Self-Assessment: giving you a completely accurate picture of your Amazon business finances, and a completely clean HMRC position. The Amazon seller accountant who understands your settlement reports, your VAT position, and what HMRC already knows about your sales.

Specialist Amazon Accounting for Every Type of Seller

Whether you are a private label seller launching your first product into Amazon FBA, a reseller operating across FBA and FBM simultaneously, an established Amazon UK seller scaling into European marketplaces, or an overseas seller storing stock in Amazon's UK fulfilment centres: your accounting needs are specific, technical, and cannot be met by a general accountant working from a standard business template.

As dedicated Amazon seller accountants and specialist FBA accountants, we work with:

UK-Based Amazon FBA Sellers

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, storing goods in Amazon's UK fulfilment centres triggers an immediate UK VAT registration obligation. We manage UK VAT registration remotely and provide ongoing quarterly VAT returns that correctly reflect deemed supplier transactions and your own direct UK sales.

Amazon FBM Sellers

Fulfilled-by-Merchant sellers still face complex Amazon accounting obligations. We ensure FBM sellers account correctly for the distinction between FBA and FBM transactions on their VAT returns, with settlement reports reconciled to gross sales.

Multichannel Sellers: Amazon and Beyond

Many Amazon sellers also operate on eBay, Etsy, Shopify, TikTok Shop, or their own storefront. We provide specialist multichannel accounting that consolidates income from every platform and presents your complete financial position accurately.

Amazon Sellers Operating Through a Limited Company

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.

Amazon Sellers Scaling into European Marketplaces

As cross-border VAT accountants for Amazon sellers, we advise on EU marketplace VAT strategy, manage OSS and IOSS registration and returns, and keep your cross-border VAT position current as EU rules continue to evolve.

Why Amazon Accounting Is Different: Why Getting It Wrong Is Increasingly Costly

The single most common mistake Amazon sellers make with their finances is treating the amount Amazon deposits into their bank account as their income. It is not. It is the net result of gross sales minus Amazon fees, refunds, advertising spend, FBA storage charges, fulfilment fees, promotional credits, and VAT adjustments: all compressed into a single figure that Amazon calls a settlement. Building your accounts from that figure produces records that are wrong in every direction:

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. A correctly prepared Amazon seller tax return reports gross sales as income and deducts Amazon fees as expenses, 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 marketplace transactions. Getting the boundary between deemed supplier and non-deemed supplier transactions wrong produces a VAT return that will not reconcile against Amazon's VAT Transaction Report.

Your Inventory Position Directly Affects Your Profit

Correctly calculating COGS, landed cost of imported stock, closing stock valuation, and write-downs that HMRC accepts all require specialist knowledge. Incorrect inventory accounting produces an incorrect tax liability.

Settlement Reports Are Not Straightforward

We reconcile your Amazon settlements correctly: mapping gross sales, fees, refunds, and adjustments to the periods to which they relate, and producing clean monthly financial records that reflect true trading activity.

Amazon VAT: What UK Sellers Need to Know in 2026

Amazon VAT is genuinely complex. Here is what every UK seller must understand.

VAT is the single biggest compliance risk for Amazon sellers, and the rules governing it have become more complex, and more actively enforced, with each passing year. HMRC's data sharing with Amazon is now comprehensive, making VAT errors easier to identify and more expensive to ignore. As specialist Amazon VAT accountants, we manage every element of your VAT position: registration, quarterly returns, deemed supplier accounting, and cross-border compliance.

UK VAT Registration Threshold and the FBA Exception

UK-based Amazon sellers must register for VAT once combined taxable turnover from all channels exceeds £90,000 in any rolling 12-month period, measured on gross sales. For overseas sellers storing stock in Amazon's UK fulfilment centres, the threshold is zero: you must register before your first UK FBA shipment.

The Deemed Supplier Rules

Amazon is the deemed supplier for goods sold by non-UK businesses to UK customers through Amazon (where goods are already in the UK), and for goods imported into the UK for sale through Amazon where consignment value is £135 or below.

Amazon is not the deemed supplier for goods sold by UK-established businesses from UK stock to UK customers, or for goods above £135 imported into the UK from outside the UK. Correctly identifying which transactions fall into each category is the foundation of a compliant Amazon VAT return.

Postponed VAT Accounting on Imports

Amazon FBA sellers who import goods from outside the UK can use Postponed VAT Accounting (PVA) to defer import VAT. We manage PVA accounting so import VAT is correctly declared each quarter and PVA statements are reconciled monthly.

Making Tax Digital for VAT and Income Tax

MTD for VAT requires digital records and HMRC-approved software. From April 2026, sole trader Amazon sellers with gross income above £50,000 must also file quarterly MTD Income Tax submissions. We assess your full MTD position and manage submissions on your behalf.

Amazon EU VAT and Cross-Border Compliance

Expanding into Amazon's European marketplaces introduces EU VAT obligations including country-specific registration or OSS enrolment. We advise on EU VAT strategy, manage OSS and IOSS, and calculate the impact of July 2026 EU customs duty changes on your pricing and landed cost.

Amazon Seller Accounting Services: Every Financial Obligation in One Place

Built around how Amazon's financial systems actually work

Every service we provide for Amazon sellers is built around settlement reports, deemed supplier rules, FBA fee structures, PVA on imports, and the MTD compliance framework rather than adapted from a standard small business accounting service.

Amazon FBA Book-keeping: Settlement Reconciliation Every Month

We reconcile your Amazon settlement reports every month, mapping gross sales, fee categories, refunds, advertising charges, and reserve movements to the correct periods, and producing monthly management accounts that show true revenue, gross margin, and cash position. We work across Xero, QuickBooks, FreeAgent, and Sage.

Amazon VAT Registration, Returns & Deemed Supplier Compliance

Complete Amazon VAT service: UK VAT registration for UK and overseas sellers, quarterly returns that correctly apply deemed supplier rules, VAT Transaction Report reconciliation, PVA for imported stock, and HMRC VAT correspondence.

Self-Assessment & Corporation Tax for Amazon Sellers

We prepare sole trader Self-assessment and limited company statutory accounts and Corporation Tax from correctly reconciled settlement data, ensuring every figure is consistent with what Amazon has reported to HMRC.

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

We calculate COGS using the landed cost method, reconcile closing stock against Amazon FBA inventory reports, account for lost or damaged inventory, and produce a monthly COGS statement so you always know your true gross margin.

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

We advise on EU VAT strategy for marketplace expansion, manage OSS and IOSS registration and returns, and ensure Pan-European FBA stock movements are correctly accounted for from a VAT perspective.

MTD Compliance: VAT and Income Tax for Amazon Businesses

We configure your accounting software with the correct Amazon integration, ensure settlement data flows digitally, and manage quarterly VAT and Income Tax MTD submissions so you are fully compliant before any deadline.

Amazon Ecommerce Tax Planning: Structure, Extraction & Growth

We review trading profit after reconciled COGS and fees, salary and dividend splits, pension contributions, inventory purchase timing, and long-term ownership structure using your actual settlement data.

Setting Up Your Amazon Business Correctly from Day One

Our Amazon seller onboarding service covers structure advice, VAT registration, cloud software setup with Amazon integration, COGS tracking from the first inventory purchase, and a financial forecast for your first 12 months.

Frequently Asked Questions

Yes, strongly advisable. Amazon settlement reports, deemed supplier VAT rules, PVA on imports, FBA inventory accounting, MTD compliance, and HMRC's platform data cross-referencing all require specific technical knowledge that a general accountant will not have. The most common errors HMRC identifies in Amazon seller accounts arise from working with a general practice unfamiliar with Amazon's financial structures.

Amazon acts as the deemed supplier for VAT on goods sold by non-UK businesses to UK customers through the marketplace and on goods imported into the UK where the consignment value is £135 or below. UK-established sellers selling from UK stock to UK customers are not covered: VAT on those sales is your direct obligation. Correctly identifying which transactions are covered is essential for a compliant Amazon VAT return.

Since January 2024, Amazon and other major digital platforms must submit annual seller reports to HMRC covering gross sales, bank details, and seller identification. HMRC cross-references these figures against your Self-assessment or Corporation Tax return automatically. If you have been booking net payouts rather than gross sales, HMRC will flag the discrepancy.

Amazon payouts are net figures after fees, storage charges, advertising, and refunds. Amazon reports your gross sales to HMRC. The correct approach is to report gross sales as income and deduct all Amazon fees and charges as allowable business expenses, arriving at taxable profit that matches HMRC's data.
