Quick answer: how far back can you claim VAT?
It depends on what you’re claiming. For goods bought before you registered, you can go back 4 years if you still have them. For services bought before registration, the limit is 6 months. For VAT you forgot to claim on earlier returns, you have 4 years from the due date of the return it belonged on. Bad debt relief and claims after deregistration have their own rules.
Key takeaways
  • Pre-registration goods: up to 4 years, but only if you still hold them.
  • Pre-registration services: up to 6 months before your registration date.
  • Missed input VAT on past returns: up to 4 years.
  • Pre-registration VAT goes on your first VAT return, so don’t leave it for later.

You’ve just registered for VAT and you’re looking at a pile of receipts from the last couple of years. Or you’ve found a supplier invoice from 2023 that never made it onto a return. Either way, the question is the same: how far back can you claim VAT, and is that money still yours to recover?

HMRC doesn’t have one deadline for everything. The limit changes with the situation, and some claims have to be made at a particular moment or they’re lost. So the honest answer to “how far can you claim VAT back?” is that it depends on which rule applies. This guide sets out each one, using HMRC’s own notices and manuals.

How Far Back Can You Claim VAT? The Time Limits at a Glance

Start with this table. Find the row that matches your situation, then read the section below it for the conditions.

Situation How far back Measured from
Goods bought before VAT registration4 years (goods still held)Your effective date of registration
Services bought before VAT registration6 monthsYour effective date of registration
Land or buildings over £250,000 bought before registrationUp to 10 years (through the Capital Goods Scheme)Your effective date of registration
Other Capital Goods Scheme items bought before registrationUp to 5 yearsYour effective date of registration
Input VAT you forgot to claim on a past return4 yearsThe due date of the return it belonged on
Correcting VAT you overpaid to HMRC4 yearsThe end of the VAT period concerned
Bad debt reliefClaim after 6 months, within 4 years and 6 monthsThe later of the payment due date and the date of supply
Services received after deregistration (form VAT427)Subject to the 4-year limitWhen the VAT was incurred

Two points run through every row. First, you need evidence, normally a valid VAT invoice addressed to your business. Second, the purchase must relate to taxable sales your business makes. VAT on costs for exempt or private activity isn’t recoverable however recent it is.

Pre VAT Registration Expenses: Goods Up to 4 Years, Services Up to 6 Months

Most people asking how far back can you claim VAT have just registered and want to recover tax on set-up costs. The law allows it, but goods and services are treated very differently, and both must be for the business that is now registered.

Goods: 4 years, if you still have them

How far back can you claim VAT on goods? Up to 4 years before your effective date of registration, as long as you still hold them on that date. Goods used to make other goods you still hold also count. Equipment, tools, vans, furniture and unsold stock usually qualify.

What doesn’t qualify is anything already gone. Fuel you’ve burned, electricity you’ve used, stock you sold and goods you’ve thrown away are all outside the rule, however recently you bought them.

Services: 6 months, and no longer

For reclaiming VAT on services, the window is much shorter: 6 months before your registration date. Think accountancy fees, website design, legal advice, consultancy and advertising. HMRC’s manual says there’s no discretion to stretch this unless your registration itself is backdated. Services linked to goods you no longer hold aren’t claimable either.

Large capital items and backdated registration

Land and buildings costing £250,000 or more, and certain other high-value capital items, follow the Capital Goods Scheme. Recovery can stretch back up to 10 years for land and up to 5 years for other qualifying items, but it’s spread over the adjustment period rather than claimed in one go. If HMRC backdates your registration, every one of these limits is measured from the new, earlier date, which can bring older purchases back into range.

Worked example: what a new registrant can claim

Example scenario (illustrative)
Priya, a self-employed joiner, becomes VAT registered from 1 October 2026. All prices below include VAT at 20%, so the VAT inside each one is the price divided by 6.
Purchase Date VAT inside Claimable?
Van, £18,000, still used in the businessMarch 2024£3,000Yes: goods held, within 4 years
Mitre saw, £720August 2022£120No: more than 4 years before 1 October 2026
Website design, £1,200May 2026£200Yes: service within 6 months
Accountancy fees, £600January 2026£100No: service more than 6 months earlier
Diesel, £3602025£60No: used up before registration
Total claim on first return£3,200

Priya can claim £3,200 of the £3,480 VAT she paid. The van is the big win. Had it been a car, the answer would usually be no, because VAT on cars is generally blocked unless the car is used only for business.

What you need to make the claim

  • Valid VAT invoices for each purchase, ideally in your business name.
  • A schedule listing each item, its date, the VAT and, for goods, confirmation you still held it at registration.
  • Timing: HMRC expects pre-registration VAT on your first VAT return, so add it there rather than holding it back.

That’s the practical answer to how far back can you claim VAT for a new registrant: check each item against its own limit. A company formed recently can use the same limits for costs incurred on its behalf before incorporation, provided they were for the company’s business. If you’re not sure your list stands up, our VAT specialist accountants can review it before you file.

How Far Can You Claim VAT Back on Past Returns? The 4-Year Rule

Once you’re registered, the question changes. It’s no longer about set-up costs but about invoices that slipped through: a supplier bill found in a drawer, a card receipt never logged, a purchase coded to the wrong account. Here, how far back can you claim VAT has a single answer: 4 years.

Under section 4.7 of VAT Notice 700/45, the clock for input VAT you under-claimed starts on the due date of the return for the period the VAT belonged to. Section 6.1 confirms that late input tax claims fall under the same 4-year cap. Miss it by a day and the money is gone.

Worked example: a forgotten laptop invoice

Example scenario (illustrative)
A design studio files quarterly returns. In October 2026 it finds a £10,800 laptop invoice from February 2023 that was never claimed, so £1,800 of VAT is missing. The invoice falls in the quarter to 31 March 2023, whose return was due on 7 May 2023. The 4 years run to 7 May 2027, so the claim is still in time. A similar invoice from the quarter to 30 June 2022 (due 7 August 2022) ran out on 7 August 2026 and can no longer be claimed.

The lesson: when you find an old invoice, check the due date of the return it belonged to, not the invoice date alone. That date decides whether claiming VAT back is still possible, and it’s the date to use whenever someone asks how far back can you claim VAT on an old invoice.

VAT error correction: next return or separate disclosure?

How you correct the error depends on its size. Notice 700/45 gives two methods.

Net value of errors What to do
£10,000 or lessAdjust on your next VAT return (Method 1)
£10,000 to £50,000, and no more than 1% of box 6 on the current returnAdjust on your next VAT return (Method 1)
Over £50,000, over the 1% test, or deliberateTell HMRC separately (Method 2)

You can always choose Method 2, even for small amounts. The studio’s £1,800 can simply go into box 4 of its next return. Keep a note of what you corrected and why, because HMRC can ask. Correct VAT errors that run in HMRC’s favour too: the same 4-year limit applies to underpaid VAT, and deliberate errors have no time limit at all.

Bad Debt Relief: 6 Months to Wait, 4 Years 6 Months to Claim

Once you are registered, bad debts are the one case where the answer to how far back can you claim VAT stretches beyond 4 years. If a customer never pays, you may already have paid HMRC the VAT on that sale. VAT Notice 700/18 lets you claim it back when all of these apply:

  • You’ve accounted for the VAT and paid it to HMRC.
  • You’ve written the debt off in your VAT accounts and moved it to a separate bad debt account.
  • The debt has been unpaid for 6 months after the later of the payment due date and the date of supply.
  • You claim within 4 years and 6 months of that later date.

For example, a £2,400 invoice (including £400 VAT) supplied on 10 January 2026 and due on 9 February 2026 can be claimed from 9 August 2026. The last day to claim is 9 August 2030. The VAT reclaim goes in box 4 of your return. That’s the longest window in this guide, but only because the first 6 months are a waiting period.

Claiming VAT Back After You Deregister (VAT427)

Your right to claim input VAT normally ends on the date your registration is cancelled. There is one exception. HMRC’s manual allows a claim for VAT on services you receive after deregistration if they relate to the business you ran while registered, such as the accountant’s fee for your final accounts or a solicitor’s bill for winding things up.

These claims are made on HMRC’s form VAT427 (often searched as VAT 427), not on a VAT return, and you need the supplier’s VAT invoice. Goods bought after deregistration don’t qualify, and the usual 4-year limit still applies to when the VAT was incurred. So even after closing, how far back can you claim VAT is still capped at 4 years.

How to Make Sure You Never Lose a VAT Claim

Knowing how far back can you claim VAT only helps if your records let you prove the claim. Five habits make sure you can claim back VAT you’re owed:

  1. Keep VAT records for at least 6 years, as GOV.UK requires, including every purchase invoice.
  2. Chase missing invoices before each return. A card receipt without a proper VAT invoice can stall a claim.
  3. Review the last quarter’s purchases for anything coded to the wrong account or left out.
  4. Build a pre-registration list as soon as registration looks likely, so nothing is missed on your first return.
  5. Use MTD software that flags unclaimed bills. Our free MTD check shows whether your set-up is ready.

Reviewer’s View (Shamayun Chowdhury)
The claims I see lost most often are services bought 7 or 8 months before registration, and invoices found after the 4-year cut-off. If you expect to register soon, choose your registration date with your recent purchases in mind, and do an invoice sweep at least once a year rather than waiting for a problem.

How Far Back Can You Claim VAT: FAQs

How far back can you claim VAT?

Up to 4 years for goods you still held when you registered, 6 months for pre-registration services, and 4 years for input VAT missed on past returns. Bad debt relief can be claimed up to 4 years and 6 months after the later of the payment due date and the date of supply.

Can I claim VAT on purchases made before I registered?

Yes, if they’re for your registered business and relate to taxable sales. Goods must still be held at registration and bought within 4 years; services must be within 6 months.

Can I claim VAT on services from a year before registration?

No. The limit for pre-registration services is 6 months, and HMRC can’t extend it unless your registration date is backdated.

What if I forgot to claim VAT on an invoice?

You can claim it on a later return if you’re within 4 years of the due date of the return it belonged on. Errors up to £10,000 can usually go straight onto your next return.

Is there a time limit on correcting VAT errors?

Yes, 4 years in most cases. Errors above £50,000, or above the 1% of box 6 test, must be reported to HMRC separately. Deliberate errors have no time limit.

Can I claim VAT back after deregistering?

Only for services received after deregistration that relate to your former business, using form VAT427. Goods bought afterwards can’t be claimed.

How do you claim VAT back on an old invoice?

If it’s within the time limit, add the VAT to box 4 of your next return (or tell HMRC separately for larger errors). You normally need a valid VAT invoice, and without one HMRC can refuse the claim.

Can a new limited company claim VAT on costs from before it was formed?

Yes. The same 4-year (goods) and 6-month (services) limits apply to costs incurred on the company’s behalf before incorporation, as long as they were for its business.
