Talk to usIf an Amazon Ads invoice includes VAT or GST, first establish whether the tax was charged correctly. An eligible refund from Amazon and reclaiming input tax through a tax return are separate processes. Gather the invoice and registration evidence before requesting a correction; a registration number alone does not establish that every charge is refundable.
This is an invoice-troubleshooting guide for authors and publishers, based on the founder’s support workflow and official sources reviewed September 26, 2026. The UK section is a limited example. Your business location, supplier, registration dates, tax scheme, and use of the advertising affect the answer; use an accountant for your own tax treatment.
1. Identify the right recovery route
| Situation | Next step | Do not assume |
|---|---|---|
| Tax may have been assessed using missing or incorrect details | Ask Amazon to review the invoice with the relevant registration evidence. | Updating an account automatically corrects earlier invoices. |
| Tax was correctly charged and may be recoverable by the business | Check the applicable tax-return rules with your accountant. | Amazon should refund every valid tax charge. |
| Registration does not cover the invoice period | Check the effective dates and local rules separately. | Registering today makes all earlier charges eligible for Amazon’s refund process. |
| The charge is a different tax or fee | Identify the line item and ask about its actual treatment. | Every extra amount on an ad invoice is VAT. |
Amazon’s tax-refund guidance requires a valid VAT/GST registration number and evidence that registration was active during the billing period. Treat those as documentation requirements for a request, not a guarantee of approval.
2. Read the invoice and gather evidence
Download the actual invoice from the relevant advertising billing account. A card statement shows a payment but may not identify the service period, tax basis, or supplier details needed to investigate the charge.
Create a small record for each invoice under review:
- Invoice number, issue date, service period, and currency.
- The supplier legal entity and the customer name and business address shown.
- The advertising account/profile and marketplace concerned.
- The amount before tax, the named tax line, its rate and amount, and the total.
- Your registration number and certificate or other evidence of its effective dates.
- Any previous credit, refund, or tax-return treatment associated with the invoice.
Use exact figures from the invoice. An ad campaign running in one country does not, by itself, settle the treatment of a business established elsewhere. Ask the adviser to consider the actual invoice and transaction rather than applying a country label based only on the Amazon marketplace.
3. Check your advertising tax details
Amazon’s current instructions for a vendor or KDP author are to open Administration → Billing → Payment Settings → Tax info and enter the VAT/GST registration number. Check that the number corresponds to your business address. See Register your Tax ID for account-specific instructions.
Confirm that you are editing the relevant advertising billing profile. Keep a dated note of the correction and inspect subsequent invoices. If the interface differs, use the current account help or ask support which profile supplies the invoice details.
Do not register for a tax solely because a short online checklist promises cheaper ads. Registration can create reporting and other obligations, and the effect depends on the whole business. Ask an adviser about both compulsory registration and any voluntary option before deciding.
4. Request an eligible Amazon refund
When your evidence supports a review, use Contact Us in Amazon Ads Support Center and submit the invoice references and registration documents. The following template helps keep the request precise. Replace the placeholders and include only statements supported by your records.
Subject: VAT/GST review request — [account/profile] — [invoice numbers]
Hello Amazon Ads Support,
Please review the [tax name] charged on the attached invoices for [business legal name]. The invoices cover [period] and show [tax amounts and currencies].
Our registration number is [number]. The attached [certificate/evidence] shows an effective date of [date] covering the period under review. The billing details currently show [relevant status], updated on [date, if applicable].
Please confirm whether these charges qualify for correction or refund under the applicable tax treatment. If additional evidence is needed, please specify it. If approved, please identify the affected invoices, any credit documents, refund method, and expected timing.
Thank you, [name and role].
Submit sensitive documents through Amazon’s designated support channel and retain the case ID. For multiple invoices, provide a clear schedule with one row per invoice and separate currency totals; do not combine different currencies into one unexplained amount.
Amazon says refund requests can take 30 days to process and that an approved request receives an estimated refund date. That is not a promise of approval or payment within 30 days. Follow the case’s actual response and ask for clarification if the decision does not address the evidence. See Amazon’s refund process.
5. Understand the UK VAT-return distinction
For a UK VAT-registered business, eligible business input VAT may be reclaimed through a VAT return. HMRC requires supporting records and valid VAT invoices; personal use, exempt activities, and the tax scheme can restrict recovery. Under the Flat Rate Scheme, purchase VAT generally cannot be reclaimed except for qualifying capital assets. Read HMRC’s business-expense guidance.
Example: a publisher receives an invoice with VAT that was correctly charged. If the expenditure qualifies for input-tax recovery, the relevant action may be recording it on the VAT return. A VAT number does not make the original invoice wrong. If the invoice instead used an incorrect tax treatment, ask about correction and the resulting accounting adjustment.
HMRC also has separate conditions for purchases before registration. These are distinct from Amazon’s requirement for registration evidence covering the billing period. An accountant should assess that question rather than treating Amazon’s refund decision as the final answer on every possible tax-return claim.
This UK example is not a country-by-country VAT/GST guide. For another jurisdiction, use the local tax authority’s current rules and an adviser familiar with your business.
6. Reconcile the outcome and your advertising costs
When Amazon responds, match the decision and any credit or refund to the original invoice. Record the amount, currency, date, case number, and supporting document. Have your accountant reconcile any tax already claimed so the same amount is not recovered twice.
If a request is refused, identify the reason before resubmitting: missing evidence, a registration-period mismatch, or a charge Amazon considers correct lead to different next steps. Keep the refusal with the invoice instead of repeatedly sending an unchanged request.
For advertising decisions, distinguish campaign spend, invoice cash payments, and the eventual business cost after the appropriate tax treatment. Do not reduce your cost assumptions by a hoped-for refund before establishing that it is recoverable. Our ACoS versus profit guide explains why campaign metrics alone do not represent every publishing expense.
If your immediate problem is ads stopping after a billing issue, use the spend-block troubleshooting guide. Tax correction and campaign delivery may require separate support actions. Adigy automates advertising management; it does not determine your tax entitlement or replace your accountant.
