You have decided to cancel your VAT registration. Maybe sales have dropped below the deregistration threshold, maybe you are winding the business down, or maybe you are leaving the UK. Then you remember the pallets sitting in Amazon's fulfilment centres, and the question hits you: what happens to the VAT on stock you cannot easily get back?
This is one of the most expensive mistakes we see Amazon sellers make. Deregistering with live FBA inventory is not just a form-filling exercise. It can trigger a VAT charge on your remaining stock, and if your circumstances have changed it can quietly leave you trading in breach of the rules.
This guide walks you through exactly what happens to your FBA stock when you deregister, when you owe VAT on it, and the overseas-seller trap that catches a lot of FBA businesses. It is for UK-based Amazon FBA sellers and their advisers. All figures are for the 2025/26 tax year and are cited to gov.uk below.
Can you deregister for VAT if you still have FBA stock?
Yes, you can deregister with FBA stock on hand, but you may have to pay VAT on that stock as part of your final VAT return. HMRC treats unsold stock and assets you still own at the cancellation date as a "deemed supply", and if the VAT due on them is more than £1,000 you must account for it.
So the stock does not stop you cancelling. It changes the cost of cancelling. The rest of this guide is about getting that cost right and avoiding the bigger trap that sits underneath it.
If VAT and stock control across marketplaces is becoming a drag on the business, our accounting support for Amazon FBA sellers is built around exactly these decisions.
When can you deregister, and when must you?
There are two routes, and they behave differently.
Voluntary deregistration. You can ask HMRC to cancel your registration if you can show your VAT taxable turnover in the next 12 months will not go above the deregistration threshold of £88,000 for 2025/26. You also have to be willing to stop charging VAT, or to drop your prices, from the cancellation date.
Compulsory deregistration. You must cancel if you are no longer eligible to be registered, for example because you have stopped trading or stopped making taxable supplies. HMRC's rule is firm here: you must cancel within 30 days if you stop being eligible, or you may be charged a penalty.
The cancellation date is either the date the reason took effect or a later date you and HMRC agree. You then submit a final VAT return for the period up to and including that date.
One thing to be clear about: dropping below £88,000 in UK turnover does not, on its own, end your VAT obligations if your stock is sitting in UK FBA warehouses. The location of the stock matters as much as the size of the turnover, as we will see below.
Do you owe VAT on your FBA stock when you deregister?
Here is the rule that catches FBA sellers. When you cancel, you must account for VAT on the stock and other assets you still hold at the cancellation date, but only if both of these are true:
- you reclaimed, or could have reclaimed, the VAT when you bought them, and
- the total VAT due on those assets is more than £1,000.
That £1,000 is a de minimis. HMRC's guidance puts it plainly: you do not have to account for the VAT if the total VAT due on the assets would be £1,000 or less. Because most FBA stock is standard-rated at 20%, that £1,000 of VAT equals £6,000 of gross, VAT-inclusive value. Hold standard-rated stock worth £6,000 or less at cancellation and there is nothing to pay. Hold more and the whole amount becomes chargeable, not just the slice above the limit.
This is a "deemed supply". You have not sold the stock to a customer, but for VAT purposes you are treated as if you supplied it to yourself at the moment of deregistration, so the input VAT you once recovered does not just disappear with your registration.
A few practical points:
- It only bites where you actually recovered, or could have recovered, the input VAT. Stock you bought from an unregistered supplier, or goods sold under a VAT margin scheme, are excluded.
- It is the VAT due on all relevant stock and assets combined, not per product line. Add up the lot before you test it against the £1,000 limit.
- FBA stock counts. Goods physically held in Amazon's UK fulfilment centres are still your stock until they sell, so they go into the calculation.
How do you value stranded FBA stock for the final return?
You do not use what you originally paid. HMRC says to value the stock at the price you would expect to pay for the same or similar goods, in their present condition, at the cancellation date. In other words, current replacement or market value, not historic cost.
For FBA stock that is good news and bad news. Slow-moving or ageing inventory may be worth far less than you paid, which lowers the VAT due. Stock that has appreciated, or that you simply cannot replace cheaply, is valued higher. If there is genuinely no market price available, you fall back to what it would cost to produce the goods at the cancellation date.
Document how you reached the figure. A dated stock report from Amazon Seller Central plus your own current-cost workings is the kind of evidence HMRC expects to see if it ever asks.
Illustrative example: the final VAT return with FBA stock
Illustrative example. Priya runs a UK limited company selling kitchenware through Amazon FBA. Her sales have fallen and she will be below the £88,000 deregistration threshold next year, so she applies for voluntary deregistration with a cancellation date of 30 June 2026.
At that date she still holds FBA stock that originally cost £18,000 net. All of it is standard-rated and she recovered the input VAT when she bought it. Because some lines are slow-moving, the current replacement value of the stock is only £12,000.
Her final VAT return calculation on the stock looks like this.
| Step | Figure |
|---|---|
| Current (replacement) value of standard-rated FBA stock | £12,000 |
| VAT due on the deemed supply (20% of £12,000) | £2,400 |
| De minimis limit (no VAT if total VAT due is £1,000 or less) | £1,000 |
| Is VAT payable? (£2,400 is over £1,000) | Yes |
| Output VAT to declare on the final return | £2,400 |
Priya adds the £2,400 to the output VAT (Box 1) on her final return, alongside the VAT on her ordinary sales for the period. If the slow-moving stock had instead been worth £6,000 or less, the VAT due would have been £1,200 or less, but only stock with VAT due of £1,000 or less escapes the charge entirely.
The lesson: the time to think about this is before you pick a cancellation date. Selling or removing FBA stock ahead of deregistration, so that the VAT due on what remains is £1,000 or less, can legitimately remove the charge. That is a planning decision, not an afterthought.
The overseas-seller trap: are you still established in the UK?
This is the part that turns a tidy deregistration into a serious problem, and it is specific to FBA.
If you are deregistering because you are leaving the UK, or because the people who actually run the business have moved abroad, you may stop being "established" in the UK while your stock stays here. That changes everything.
HMRC treats you as established in the UK if either the place where essential management decisions are made and your central administration is carried out is in the UK, or you have a fixed establishment here with the permanent human and technical resources to make or receive supplies. A registered office, a virtual address, or a warehouse alone is not enough. A company incorporated in the UK is not automatically established here.
If you are no longer established in the UK but you still hold stock in UK FBA warehouses and sell it to UK customers, you become a non-established taxable person (NETP). And the registration rules for an NETP are unforgiving: there is no registration threshold. You must notify HMRC and register if you make taxable supplies of any value in the UK. The £90,000 registration threshold and the £88,000 deregistration threshold simply do not apply to you.
So the trap runs like this. You deregister thinking you are below the threshold, but your stock is still in FBA and you are now overseas. You are no longer entitled to use the threshold at all, your continued FBA sales create an immediate obligation to be registered as an NETP, and you may have cancelled a registration you were not allowed to cancel. This is why "established in the UK" is the single most important question to settle before you file anything.
What about Amazon's deemed-supplier rules?
There is a second layer that interacts with all of the above, and it is widely misunderstood.
Since 1 January 2021, where goods are in the UK at the point of sale and an overseas business sells them to a UK consumer through an online marketplace, the marketplace, not the seller, accounts for the VAT on that sale. In that situation the overseas seller is treated as making a zero-rated "deemed supply" of the goods to the marketplace, and Amazon charges and remits the VAT to the customer.
That sounds like it lets an overseas FBA seller off the hook, but it does not remove the registration question:
- The seller is still liable for import VAT when the goods first enter the UK, and only a VAT-registered seller can reclaim that import VAT. Deregister and you lose the ability to recover it, turning a recoverable cost into a permanent loss of margin.
- An NETP making only zero-rated deemed supplies can apply to HMRC for exemption from registration, but that is an application you make, not an automatic status. You do not just stop being registered and assume it is handled.
- Amazon now runs its own UK "business establishment" checks and can suspend disbursements where it cannot satisfy itself that a seller is UK-established. Your VAT position and your Amazon account standing are linked.
In short, the marketplace handling the VAT on the final sale does not mean you can walk away from your own registration cleanly while stock is stranded in FBA. It changes who declares the output VAT on the sale, not whether you have UK obligations.
Decision steps before you cancel
Run through these in order before you submit a VAT7 or apply online.
- Confirm why you are deregistering. Below the £88,000 threshold, or ceasing to trade, or leaving the UK? The reason sets the rules.
- Check your establishment. Are essential management decisions and central administration genuinely still in the UK? If not, you may be an NETP with a nil threshold and cannot rely on the deregistration threshold at all.
- Pull a dated FBA stock report. Know exactly what you hold in Amazon's UK warehouses at your proposed cancellation date.
- Value the stock at current replacement value and work out the VAT due. Over £1,000 of VAT due means it goes on the final return.
- Consider selling or removing stock first. Reducing the remaining VAT due to £1,000 or less removes the deemed-supply charge legitimately.
- Decide the cancellation date deliberately. It drives the period of your final return and the stock snapshot.
- Get a second opinion if you sell internationally. The interaction of FBA, NETP status and the marketplace rules is where the costly mistakes live.

Frequently asked questions
Do I have to pay VAT on Amazon FBA stock when I deregister?
Only if you recovered the input VAT when you bought it and the total VAT due on all your remaining stock and assets is more than £1,000. For standard-rated goods that £1,000 of VAT equals £6,000 of gross value. Below that, there is nothing to pay; above it, the whole amount is chargeable on your final return.
How do I value my FBA stock for the final VAT return?
Use the current price you would expect to pay for the same or similar goods in their present condition at the cancellation date, not the original cost. A dated Amazon Seller Central stock report plus your own current-cost workings is the evidence HMRC expects.
Can I deregister if my turnover is below £88,000 but my stock is still in FBA?
If you are still established in the UK, yes, subject to accounting for VAT on the remaining stock. But if you are no longer established in the UK, the £88,000 deregistration threshold does not apply to you at all. As a non-established taxable person you must be registered if you make taxable supplies of any value here.
Doesn't Amazon handle the VAT, so I can just deregister?
Amazon accounts for the VAT on the final sale to the customer only where the goods are in the UK and sold by an overseas seller through the marketplace. That does not remove your own obligations: you are still liable for import VAT, you need to be registered to reclaim it, and an exemption from registration is something you apply for, not an automatic result of deregistering.
What happens if I deregister when I should not have?
If you cancel a registration you were not entitled to cancel, for example as an NETP making non-zero-rated supplies, you can be required to register again, account for the VAT you should have charged, and face penalties. Settling your establishment status before you file is the way to avoid this.
Should I sell my FBA stock before I deregister?
It can be sensible. If selling or removing stock brings the VAT due on what remains down to £1,000 or less, the deemed-supply charge falls away entirely. This is legitimate planning, but the timing has to line up with your chosen cancellation date.
