Most people think VAT only matters from the day they register. But HMRC actually lets you reclaim VAT on certain purchases you made before your VAT number even existed.
If you missed this when you registered, you might have left cash sitting on the table. Here’s how it works and what you can do about it.
How far back can you go?
Goods : stock, assets or equipment you still have or still use can be claimed for up to 4 years before registration.
Services : things like marketing, software or accountancy can be claimed for up to 6 months before registration.
There’s a catch: HMRC expects these claims to be made on your first VAT return. If you missed that, you’ll need to go through an error correction or voluntary disclosure process.
What counts as “goods”?
Anything you physically bought for the business that you still own or use at the date you registered, for example, computers, tools, or furniture. Services like advertising or consultancy don’t count as goods.
How to make a late claim
Gather your invoices – they must show VAT, your business name, and be for eligible goods.
Prove you still have them – photos, stock lists or asset registers will help.
Create a simple schedule – date, supplier, invoice number, description, net, VAT, gross, and where the item is now.
Submit via your accountant – they can use HMRC’s VAT652 form or the agent portal to explain the oversight and request the reclaim.
What HMRC checks before paying out
That the claim is for goods, not services.
That you still have or use the goods.
That the invoices are valid and haven’t been claimed before.
That your claim is reasonable and backed up with evidence.
Why this matters
Reclaiming pre-registration VAT could mean hundreds or even thousands of pounds back in your pocket. But once the window closes, it’s gone for good.
If your accountant didn’t mention it when you registered, it’s worth asking why, and seeing if there’s still a route to recover what you’re owed.
