Why Amazon Seller Accounting Matters in 2026/27
Amazon seller accounting is not just about recording Amazon payouts. A UK Amazon business has to track gross sales, Amazon referral fees, FBA fees, FBM postage, storage charges, advertising spend, refunds, VAT, Cost of Goods Sold, import duty, inventory value, bank deposits, payment reserves and HMRC deadlines. If your bookkeeping only records the net amount Amazon deposits into your bank, your accounts will be wrong.
Amazon sellers often grow quickly. A product can go from ten sales a week to hundreds of units a month after a successful PPC campaign, TikTok review or seasonal spike. Fast growth creates cash flow pressure because stock must be purchased before profit is realised. Without proper Amazon bookkeeping, it becomes difficult to know whether the business is genuinely profitable or simply moving large volumes with thin margins.
For the 2026/27 tax year, Amazon sellers should pay particular attention to VAT, Making Tax Digital, platform reporting, Self Assessment deadlines and Corporation Tax planning. HMRC can compare digital platform income, bank deposits and tax returns. That means every serious Amazon seller needs accurate records, a clean chart of accounts and a monthly reconciliation system.
Who This Guide Is For
This Amazon seller accounting guide is written for UK-based FBA, FBM, MCF and multi-channel sellers. It applies whether you sell as a sole trader, partnership or limited company, and whether you use Amazon.co.uk, Pan-European FBA, Shopify, eBay, TikTok Shop or your own website alongside Amazon.
Business Structures for Amazon Seller Accounting
Your business structure decides how tax is calculated, what deadlines apply, how profits are extracted and how formal your accounting records need to be. Most Amazon sellers begin informally, but once sales become regular, you should decide whether you are operating as a sole trader, partnership or limited company.
Sole Trader
Simple to start and easy to manage. You report profits through Self Assessment and pay Income Tax and Class 4 National Insurance on taxable business profits.
Limited Company
A separate legal entity. The company pays Corporation Tax on profits, files annual accounts and can pay directors through salary and dividends.
Partnership
Two or more people run the Amazon business together. The partnership files a return and each partner reports their profit share personally.
Sole Trader Amazon Seller
A sole trader setup is usually suitable for a new Amazon seller testing products, learning FBA, or selling at modest volume. You do not need to create a company, but you still need to keep records of income and expenses. If your total self-employed trading income exceeds the trading allowance, you may need to register for Self Assessment and report your profits.
Limited Company Amazon Seller
A limited company can be useful once the business becomes more profitable, needs investment, works with suppliers, carries product liability risk or wants a more formal structure. The company pays Corporation Tax on taxable profits. Directors may take a salary, dividends or both, depending on the tax plan. Limited companies also have Companies House filing duties and must keep proper statutory records.
Partnership Amazon Business
A partnership may be suitable where two people jointly run the Amazon store. For example, one partner may manage sourcing and suppliers while the other handles PPC and operations. Partnership accounting must clearly show profit shares, capital introduced, drawings, partner expenses and Self Assessment information for each partner.
Structure Is a Tax Planning Decision
Do not switch to a limited company only because someone online says it saves tax. The right structure depends on profit, reinvestment plans, VAT, risk, director pay, stock ownership, loans, personal income and admin cost. Speak to a UK accountant before transferring an Amazon business into a company.
Setting Up Amazon Seller Accounting & Bookkeeping
A clean bookkeeping system makes Amazon accounting easier every month. The goal is simple: every Amazon payout should match a settlement, every settlement should split sales and fees correctly, every product sold should move cost from inventory to COGS, and every VAT return should be backed by proper digital records.
-
Open a Dedicated Business Bank Account
Keep Amazon money separate from personal spending. All Amazon payouts, supplier payments, software costs, PPC charges, freight costs and business expenses should pass through a dedicated business bank account. This makes reconciliation faster and protects you from messy tax records.
-
Choose Accounting Software
Use cloud accounting software such as Xero, QuickBooks Online, FreeAgent or Sage. For VAT-registered sellers, the software should support Making Tax Digital for VAT. For sole traders affected by MTD for Income Tax, check that your software supports digital record keeping and quarterly updates.
-
Connect Amazon Settlement Automation
Amazon does not send a simple sales invoice to your bookkeeping system. Settlement reports contain many transaction types. Tools such as A2X or Link My Books can summarise Amazon settlements and post sales, VAT, fees, refunds and reserves into Xero or QuickBooks.
-
Create a Proper Chart of Accounts
Your chart of accounts should separate Amazon sales, shipping income, FBA fees, referral fees, storage fees, advertising, software, freight, import duty, COGS, inventory, refunds, VAT control accounts and bank fees. Avoid one generic “Amazon expenses” account because it hides margin problems.
-
Record Inventory as an Asset
Stock purchased for resale is not usually an immediate expense. It is inventory on the balance sheet until sold. When a product is sold, its cost moves to Cost of Goods Sold. This is one of the most important parts of Amazon seller bookkeeping because inventory mistakes distort both profit and tax.
-
Reconcile Every Month
Monthly reconciliation keeps the business under control. Match Amazon payouts to settlements, reconcile bank feeds, check advertising invoices, record supplier bills, update stock values, review VAT codes and produce a monthly profit report. Leaving everything until January creates stress and errors.
Record Keeping Rule
Keep Amazon reports, supplier invoices, VAT invoices, import documents, bank statements, PPC invoices, software receipts and stock records. A strong digital filing system makes year-end accounts, VAT checks and HMRC questions much easier to handle.
VAT for Amazon Sellers - Complete UK Guide 2026/27
VAT is one of the biggest issues in Amazon seller accounting UK. The VAT registration threshold is based on taxable turnover, not profit. This matters because Amazon sellers can have high turnover but low net profit after product costs, Amazon fees, advertising and shipping. You must monitor turnover monthly, not just at year end.
VAT Rates for Amazon Products
| VAT Rate | Rate | Common Amazon Product Examples | Accounting Note |
|---|---|---|---|
| Standard Rate | 20% | Electronics, adult clothing, tools, beauty products, homeware, toys and accessories | Most Amazon products fall here, but always check product-specific VAT rules. |
| Reduced Rate | 5% | Selected categories such as children’s car seats and certain home energy products | Use only where the product genuinely qualifies. |
| Zero Rate | 0% | Many books, children’s clothing and selected food products | Still counts as taxable turnover for VAT threshold purposes. |
| Exempt / Outside Scope | N/A | Limited cases depending on product or service type | Do not assume an item is exempt without checking VAT guidance. |
VAT on Amazon Fees
Amazon charges VAT on many seller fees where applicable. VAT-registered sellers may be able to reclaim input VAT on eligible Amazon fees if they hold valid VAT invoices and the costs relate to taxable business activity. Your accounting software should separate net expense and input VAT correctly.
VAT on FBA, FBM and MCF Sales
FBA, FBM and MCF can create different accounting flows. FBA orders are fulfilled by Amazon. FBM orders are fulfilled by you or your 3PL. MCF orders may come from Shopify, eBay, TikTok Shop or your website but be fulfilled by Amazon. The VAT treatment should follow the sales channel, customer location, marketplace rules and product VAT rate. Do not treat every Amazon-related shipment as the same VAT scenario.
Pan-European FBA VAT
If Amazon stores your stock in EU fulfilment centres, you may trigger VAT registration and reporting obligations in those countries. Pan-European FBA can improve delivery speed, but it increases compliance complexity. UK sellers using EU storage should speak to a VAT adviser before activating cross-border stock placement.
Making Tax Digital for VAT
VAT-registered Amazon sellers should maintain digital records and submit VAT returns through MTD-compatible software. Manual copying from spreadsheets into the HMRC portal is not a modern VAT process. A clean Amazon accounting stack should connect Amazon reports, accounting software and VAT return preparation in a controlled workflow.
VAT Mistake to Avoid
Do not wait until you receive £90,000 in bank payouts before registering for VAT. The threshold is taxable turnover, not bank deposits, not profit and not the net amount after Amazon fees.
Amazon Seller Tax - Income Tax, National Insurance & Corporation Tax
Amazon seller tax depends on your structure. Sole traders pay Income Tax and Class 4 National Insurance on profits through Self Assessment. Limited companies pay Corporation Tax on company profits and directors may pay personal tax on salary and dividends. Partnerships allocate profits to partners, who report their shares personally.
Sole Traders — Income Tax 2026/27
For England, Wales and Northern Ireland, the standard Personal Allowance is £12,570. Tax rates then apply by band. Scottish income tax bands differ, so Scottish-resident Amazon sellers should check Scottish rates separately.
| Band | Taxable Income | Income Tax Rate | Amazon Seller Note |
|---|---|---|---|
| Personal Allowance | Up to £12,570 | 0% | Allowance can reduce if adjusted net income exceeds £100,000. |
| Basic Rate | £12,571 to £50,270 | 20% | Applies to taxable profits within this band. |
| Higher Rate | £50,271 to £125,140 | 40% | Profit planning and pension contributions may become important. |
| Additional Rate | Over £125,140 | 45% | Consider accountant-led planning if profits reach this level. |
Self-Employed National Insurance 2026/27
Self-employed Amazon sellers may pay Class 4 National Insurance when profits exceed the relevant threshold. For 2026/27, Class 4 National Insurance is 6% on profits over £12,570 up to £50,270, and 2% on profits above £50,270. Class 2 contributions are generally treated as paid for qualifying profits, with voluntary Class 2 possible for low profits.
Limited Companies — Corporation Tax 2026
Limited company Amazon sellers pay Corporation Tax on taxable company profits. For financial year 2026, the small profits rate is 19% for companies with profits under £50,000 and the main rate is 25% for companies with profits over £250,000. Companies between those limits may receive marginal relief, creating a gradual increase in effective rate.
| Company Profit Level | Corporation Tax Position | Planning Note |
|---|---|---|
| Under £50,000 | 19% small profits rate | Check associated company rules if you own more than one company. |
| £50,000 to £250,000 | Main rate with marginal relief | Effective tax rate rises gradually; planning can matter. |
| Over £250,000 | 25% main rate | Budget corporation tax monthly to avoid cash flow shocks. |
Allowable Expenses for Amazon Seller Accounting
Allowable expenses reduce taxable profit when they are incurred wholly and exclusively for business purposes. The important point is to separate personal spending, capital purchases, inventory costs, direct costs and overheads correctly. Amazon businesses often make mistakes by treating stock purchases as normal expenses instead of inventory.
Stock & COGS
Product purchase cost, freight, import duty, inspection, prep, packaging and inbound shipping should be tracked as landed cost and COGS.
Amazon Fees
Referral fees, FBA fulfilment fees, storage fees, refund administration, removal fees and subscription fees should be coded separately.
Amazon PPC
Sponsored Products, Sponsored Brands and Sponsored Display advertising should be tracked separately from selling fees.
Software & Tools
Xero, QuickBooks, A2X, Link My Books, Helium 10, Jungle Scout, repricers and inventory tools are common ecommerce software costs.
Shipping & Freight
Supplier freight, FBA inbound shipping, FBM postage, courier charges and 3PL costs should be split by type where possible.
Home Office
If you run your Amazon business from home, you may claim a reasonable business-use portion of eligible costs or use simplified expenses.
Inventory vs Expense
A common Amazon bookkeeping mistake is posting every supplier payment directly to expenses. If the payment is for stock that has not yet sold, it should usually sit in inventory. The expense appears as COGS only when the stock sells. This difference is critical because large stock purchases can make cash flow look worse while profit is not reduced until goods are sold.
Landed Cost for Amazon Sellers
Your true unit cost includes more than the supplier invoice. Landed cost can include factory price, shipping to the UK, import duty, customs clearance, inspection, prep centre costs, labelling, polybagging, bundling and freight to Amazon. If you ignore landed cost, product margins will look better than reality.
- Supplier product cost
- International freight and shipping insurance
- Import duty and customs clearance
- Prep centre, labelling, bundling and packaging
- Amazon inbound shipping costs
- Quality control and inspection costs
- Exchange rate differences on supplier payments
Amazon Settlement Reports — What You Need to Know
Amazon settlement reports are the backbone of Amazon seller bookkeeping. A settlement is not just a payout. It contains gross sales, refunds, Amazon fees, shipping credits, promotional rebates, marketplace facilitator VAT, advertising charges, reserves, previous balances and adjustments. Recording only the amount received in the bank is one of the biggest Amazon accounting errors.
What Is Inside an Amazon Settlement?
- Product sales — gross sales before Amazon fees
- Shipping income — shipping charged to customers where applicable
- Referral fees — Amazon commission on sales
- FBA fulfilment fees — pick, pack and ship fees
- Storage fees — monthly and aged inventory storage charges
- Advertising charges — Amazon PPC and campaign spend
- Returns and refunds — customer refunds and adjustments
- VAT data — VAT collected or charged depending on transaction type
- Account reserves — amounts held by Amazon before release
- Net payout — the final bank deposit after all activity
Do Not Book Net Payout as Revenue
If Amazon deposits £8,000 into your bank, that is not your revenue. Your gross sales may be £12,000, with fees, refunds, advertising and reserves deducted before payout. Accurate Amazon seller accounting records gross sales and deductions separately.
Amazon Seller VAT Reports and Tax Document Library
Amazon Seller Central contains reports that support VAT, bookkeeping and audit evidence. VAT-registered sellers should download tax invoices, VAT calculation reports, disbursement reports, advertising invoices and settlement data monthly. If you use Amazon VAT Calculation Service, remember that Amazon may calculate VAT on invoices, but your business still needs accurate bookkeeping and VAT return review.
Monthly Reports to Download
- Amazon settlement reports
- Amazon transaction reports
- Amazon VAT invoices and fee invoices
- Amazon advertising invoices
- Inventory reports and stock movement reports
- FBA fee preview or fulfilment reports
- Return and refund reports
- Business reports for sales analysis

Recommended Accounting Software for Amazon Sellers
The best Amazon seller accounting software depends on your size and complexity. A new sole trader may be fine with FreeAgent or QuickBooks plus spreadsheets. A high-volume FBA seller usually needs Xero or QuickBooks with A2X or Link My Books. A multi-channel seller with stock in several warehouses may need inventory software as well.
| Software | Best For | Amazon Use Case | Accounting Note |
|---|---|---|---|
| Xero | Growing sellers and limited companies | Bank feeds, VAT, tracking categories, reporting | Works well with A2X and ecommerce integrations. |
| QuickBooks Online | Small to medium ecommerce sellers | Bank reconciliation, classes, VAT, reporting | Good alternative to Xero for Amazon bookkeeping. |
| FreeAgent | Sole traders and simple businesses | Basic bookkeeping, VAT, bank feeds | Often suitable for early-stage sellers. |

| Veeqo / Inventory Tools | Stock and order management | Multi-channel stock visibility and fulfilment | Useful when selling across Amazon, Shopify and eBay. |
Common Amazon Seller Accounting Mistakes
1. Recording Net Amazon Payouts as Revenue
This is the most common mistake. Net payouts hide gross sales, refunds, fees, VAT and reserves. Always record the settlement breakdown, not only the bank deposit.
2. Not Tracking COGS Properly
If you do not post Cost of Goods Sold when products sell, profit will be inaccurate. Stock purchases should flow through inventory and only become COGS when sold.
3. Missing VAT Registration Timing
The VAT threshold is based on rolling taxable turnover. Fast-growing Amazon sellers can cross it before they realise. Monitor sales monthly and plan pricing before VAT registration becomes mandatory.
4. Mixing Personal and Business Spending
Personal transactions in the business bank account slow down bookkeeping and increase the chance of errors. Use a separate bank account and separate business card.
5. Ignoring Advertising Profitability
Amazon PPC can make sales rise while profit falls. Track advertising cost by product or SKU wherever possible. Review TACOS, ACOS, gross margin and net margin together.
6. Forgetting Import VAT and Duty
Imported stock may involve duty, freight, customs fees and import VAT. These amounts affect landed cost, VAT recovery and COGS. Keep C79 certificates, PVA statements and freight invoices.

Frequently Asked Questions — Amazon Seller Accounting UK
You are not legally required to use an accountant, but it is strongly recommended once your Amazon business has regular sales, stock imports, VAT registration, FBA fees, multiple channels or significant profit. A specialist ecommerce accountant can help with VAT, COGS, settlement reconciliation and tax planning.

No. The payout is the net amount after sales, refunds, fees, reserves and other deductions. You should record the full settlement breakdown so gross sales, Amazon fees, VAT and refunds are shown correctly.
Unsold FBA stock is normally inventory on the balance sheet. It becomes Cost of Goods Sold when units are sold. Stock in transit, stock in Amazon warehouses and stock at prep centres should be included in inventory records if owned by the business.
Yes, Amazon referral fees, FBA fulfilment fees, storage fees, subscription fees, advertising charges and other business-related Amazon fees are generally allowable business costs. They should be coded separately for accurate profitability reporting.
If you are VAT registered and have the correct import VAT evidence, you may be able to reclaim import VAT under normal rules. Keep C79 certificates, postponed VAT accounting statements and freight/import documents.
