TITLE: Key VAT and Compliance Tasks for Ecommerce Sellers: Week of 31 August 2026

The week of 31 August 2026 brings important compliance tasks for Amazon and Shopify sellers. Review your Pan-EU FBA listings, update your VAT reconciliation process, and prepare your records while HMRC considers further marketplace changes.

Protect Pan-EU FBA eligibility before 3 September

Amazon has confirmed that every Pan-European FBA product must have an active offer on the Netherlands marketplace from 3 September 2026. This applies to both new and existing Pan-EU FBA products.

A similar requirement will apply to Belgium from 26 February 2027.

This is an important operational change for UK Limited Companies selling across Europe. If a product does not have the required active offer, it may lose eligibility for Pan-EU FBA benefits.

Complete this Amazon checklist

• Review every ASIN enrolled in Pan-EU FBA.
• Confirm that the product has an active offer on Amazon.nl.
• Check that the listing uses the correct SKU and product information.
• Resolve suppressed, inactive, or incomplete listings.
• Record the date each offer was checked.
• Schedule a second review before the Belgium requirement begins.

Amazon’s official Pan-European FBA guidance confirms that the Netherlands and Belgium listing requirements do not automatically mean that you must store stock in those countries.

An active offer alone does not automatically create a Dutch or Belgian VAT registration obligation when your stock is held elsewhere. However, your VAT position still depends on your establishment, fulfilment model, inventory locations, customer type, and use of the Union One Stop Shop.

Do not confuse listing activity with inventory storage. Storing goods in another country can create local VAT registration and reporting obligations. Review Amazon’s inventory movement reports so you know where your goods are physically held.

For UK sellers using Pan-EU FBA, this distinction is central to accurate Amazon Pan-European VAT compliance.

Reconcile Amazon’s shipment-level VAT calculations

Amazon’s VAT Calculation Service moved to shipment-level VAT calculation on 1 June 2026.

Previously, Amazon calculated and rounded VAT separately for each unit. The new method groups items by tax rate and calculates VAT on the total invoice amount before rounding.

This can create small differences between Amazon’s VAT reports and your accounting system.

For example:

• Six units priced at £1.99 each.
• VAT rate of 10%.
• Unit-level calculation: £1.99 × 10% = £0.199, rounded to £0.20 per unit.
• Total under the old method: £1.20.
• Shipment-level calculation: £11.94 × 10% = £1.194, rounded to £1.19.

The difference is only one pence. However, repeated across thousands of orders, these discrepancies can affect VAT control accounts, invoice matching, and month-end reporting.

Update your reconciliation process

Use Amazon’s actual reports as the source for the VAT amount charged on each shipment. Do not rely only on a per-unit calculation in your bookkeeping software.

Your process should:

1. Group items by shipment and VAT rate.
2. Calculate VAT on the aggregated amount.
3. Round the total at shipment level.
4. Compare the result with Amazon’s VAT Calculation Report.
5. Record any rounding difference in a controlled rounding account.
6. Check refunds and credit notes against the original shipment calculation.

The Amazon VAT Calculation Service methodology explains that sellers remain responsible for ensuring their VAT settings, product tax codes, VAT registration numbers, and ship-from locations are accurate.

This is particularly important for sellers using both Amazon FBA and seller-fulfilled orders. The actual ship-from location can affect the VAT treatment.

A reliable Amazon FBA accounting UK process should reconcile:

• Product sales.
• Customer VAT.
• Amazon-collected VAT.
• Seller-accounted VAT.
• FBA fulfilment fees.
• Storage and removal fees.
• Refunds and reimbursements.
• Currency conversion differences.
• Inventory movements between fulfilment centres.

Prepare for possible UK marketplace VAT changes

HMRC’s consultation on extending online marketplace VAT liability closed on 18 August 2026. The government response is still pending.

The proposal considers extending marketplace VAT liability to certain sales made by UK-based businesses through online marketplaces. The consultation also considered measures such as a minimum platform threshold and VAT rate relief for businesses below the VAT registration threshold.

There is no confirmed implementation date or new rule for UK sellers at the time of writing. Current VAT responsibilities continue to apply.

You should still prepare your records now. This will save time if new reporting or marketplace data requirements are introduced.

Organise the data HMRC may need

Maintain a clear record of:

• Marketplace sales by platform.
• Direct website sales.
• Total taxable turnover.
• Sales by legal entity.
• UK and overseas customer locations.
• VAT-registered and non-VAT-registered customers.
• Returns, refunds, and discounts.
• Marketplace fees and deductions.
• Inventory held in the UK and overseas.
• VAT collected by marketplaces.
• VAT accounted for by your company.

The UK VAT registration threshold remains more than £90,000 of taxable turnover in a rolling 12-month period. The optional deregistration limit remains less than £88,000.

Use HMRC’s VAT threshold guidance and monitor your turnover every week. Do not wait until your year-end accounts are prepared. A rolling calculation gives you earlier notice of a potential registration obligation.

Strengthen Shopify and Amazon bookkeeping before growth accelerates

Growth can hide accounting problems. A business may show strong sales while losing margin through VAT leakage, marketplace fees, refunds, currency movements, and slow inventory turnover.

Your ecommerce bookkeeping UK process should connect sales data with cash, inventory, VAT, and profitability. Recording only bank deposits is not enough because marketplace payouts are usually net of fees, refunds, reserves, and adjustments.

For Shopify sellers, Shopify accounting UK should separately identify:

• Gross online sales.
• Shopify Payments settlements.
• PayPal and other payment providers.
• Transaction and subscription fees.
• Refunds and chargebacks.
• VAT collected at checkout.
• Shipping income and costs.
• Marketing and fulfilment expenses.

For Amazon sellers, the same principle applies. Your records should be built from transaction-level reports rather than payout totals.
