Crossing the £90k VAT Threshold as a UK Etsy or Amazon Seller: The Pricing Model to Run First
Most growing UK marketplace sellers think about VAT registration as admin: forms, returns, bookkeeping and accountant calls. That part matters. But the pricing effect matters too.
Most growing UK marketplace sellers think about VAT registration as admin: forms, returns, bookkeeping and accountant calls. That part matters. But the pricing effect matters too.
When you register for VAT, a product that looked profitable before registration may need a new price model. Output VAT, input VAT, marketplace fees and seller-fee VAT all start interacting.
This guide explains the planning model. It is not tax advice.
First, the rule itself
GOV.UK currently says businesses must register for VAT if total VAT-taxable turnover for the last 12 months goes over £90,000. It also says you must register if you expect turnover to go over £90,000 in the next 30 days alone.
"VAT-taxable turnover" is the important phrase. It is not simply "all marketplace cash in the bank" for every possible seller. Check the GOV.UK registration guidance and your own position.
What changes in your per-sale model
Two lines change at the same time.
1. Output VAT is separated from revenue
For a VAT-registered seller, VAT charged to the buyer is not your income. If your marketplace price is VAT-inclusive, a £20 standard-rate sale contains about £3.33 of output VAT:
``text net revenue = gross price / 1.20 output VAT = gross price - net revenue ``
That does not mean every product should rise by exactly 20%. It means you need to model whether your existing marketplace price absorbs the VAT or whether you change prices.
2. Eligible VAT on costs may become reclaimable
The positive side is input VAT. VAT-registered sellers may be able to reclaim eligible VAT on marketplace seller fees, stock, packaging, equipment and overheads, subject to normal VAT rules and invoices.
For the default Etsy worked example in our Studio, a £20 item plus £3.95 shipping has about £2.96 of seller fees before VAT and about £0.59 of fee VAT. For a non-registered seller, that fee VAT is modelled as a cost. For a registered seller, it is modelled as potentially reclaimable input VAT.
Why the two-way comparison matters
The output VAT you separate from revenue may be larger than the fee VAT you reclaim. But the full result depends on your product costs, input VAT, category fees, VAT rate, pricing and whether your goods are standard-rated, zero-rated, reduced-rated or exempt.
That is why a one-line rule like "registration always kills margin" is not good enough. Run the same sale twice:
- Not VAT-registered: no output VAT charged; seller-fee VAT is treated as a cost.
- VAT-registered: output VAT is separated from revenue; eligible fee VAT is modelled as reclaimable.
Then compare:
- profit in each case,
- output VAT separated from revenue,
- fee VAT potentially reclaimed,
- the price required to keep a target margin.
Why to model it before crossing £90k
Before crossing the threshold, you can review pricing calmly. You can test a gradual price rise, reduce exposure to weak-margin products, and prepare bookkeeping records.
After crossing, registration timing and effective-date rules matter. GOV.UK says that when you exceeded the threshold in the last 12 months, you have 30 days from the end of the month when you went over to register, and the effective registration date is the first day of the second month after you go over.
The exact dates are a compliance question for GOV.UK or your accountant. The pricing point is simpler: do not wait until the admin deadline to discover that a best-seller needs a different price.

Takeaway
The £90k VAT threshold is not only an admin question. For marketplace sellers, it is a pricing-model question.
Run the same product as not-registered and registered before you need the answer. Then take the model to your own fee statement, GOV.UK guidance and accountant.
