When your business crosses the VAT threshold or registers voluntarily, you do not lose the VAT you paid on purchases in the run-up to registration. HMRC allows you to recover certain pre-registration VAT on your very first return, provided you meet the conditions. This guide explains the two key time limits, the rules that apply, and how to calculate your claim, using a worked example based on an effective registration date of 1 May 2026.

The two pre-registration time limits

HMRC applies different rules to goods and to services. Getting this distinction right is the single most important step, because it determines how far back you can look.

Goods – the 4-year rule

You can reclaim VAT on goods you bought up to four years before your effective date of registration, as long as those goods are still held by the business at the registration date. “Goods” includes stock for resale, raw materials, equipment, tools, computers, fixtures and fittings – anything that still exists in the business when you register.

You cannot reclaim VAT on goods that were already used up, sold on, or consumed before registration, because they no longer form part of your taxable business assets at that point.

Services – the 6-month rule

You can reclaim VAT on services supplied to the business in the six months before your effective date of registration. Typical examples include accountancy and legal fees, marketing, software subscriptions, consultancy and professional advice. The services must relate to the taxable business activities you carry on after registration.

Conditions you must meet

Regardless of whether you are reclaiming on goods or services, the following conditions apply to every claim:

• The expense was incurred by the entity that is now registered for VAT (the same legal person or business).
• The goods or services relate to taxable supplies you make – not to exempt activities or to private, non-business use.
• You hold a valid VAT invoice for each purchase showing the supplier’s VAT number and the VAT charged.
• For goods, they are still on hand at the date of registration (stock not yet sold, assets still in use).
• The VAT was charged by a UK VAT-registered supplier – you cannot reclaim VAT that was never validly charged.
• If HMRC gives you a backdated registration date, that date – not the date you applied – is used to work out the 4-year and 6-month windows.

What you cannot reclaim

• VAT on goods bought more than 4 years before registration.
• VAT on services received more than 6 months before registration.
• VAT on goods that were sold, scrapped or fully consumed before the registration date.
• VAT on items used for private purposes or for making VAT-exempt supplies.
• VAT where you do not hold a valid VAT invoice as evidence.

Assets used before registration: HMRC may expect an apportionment

This is the area HMRC most often challenges. Where a capital asset (for example a van, laptop or machinery) was bought within the 4-year window but was already used in the business before registration, HMRC’s view is that you should reduce the VAT claim to reflect that pre-registration use – you reclaim only the proportion relating to your taxable activity going forward, not necessarily the full VAT.

This position is set out in HMRC’s VAT Input Tax Manual (VIT32000) and Revenue and Customs Brief 16 (2016). Officers have issued assessments to businesses that reclaimed pre-registration asset VAT in full without apportioning, so it is worth getting this right on the first return.

If you are on the Flat Rate Scheme

The pre-registration rules work differently under the VAT Flat Rate Scheme. If you join the Flat Rate Scheme, you generally cannot reclaim pre-registration input tax in the normal way – the one exception is capital assets where the VAT-inclusive cost is more than £2,000. Factor this in if you intend to register and adopt the Flat Rate Scheme at the same time.

How to make the claim

1. Identify all qualifying purchases within the 4-year (goods) and 6-month (services) windows.
2. Confirm goods are still held at the registration date and that everything relates to taxable supplies.
3. Gather and retain the valid VAT invoices supporting each amount.
4. Add the recoverable VAT to the input tax (Box 4) on your first VAT return.
5. Keep a clear schedule of the pre-registration claim in case HMRC asks to see it.

Frequently asked questions

Can I reclaim VAT on equipment bought three years before registering?

Yes, provided the equipment is still owned and used by the business at your registration date and relates to your taxable supplies. Equipment is treated as goods, so the 4-year window applies.

Can I reclaim VAT on my accountant’s fees from before registration?

Accountancy work is a service, so you can reclaim VAT on fees received in the six months before your effective registration date, as long as they relate to your taxable business.

What if I bought stock more than four years ago?

VAT on goods purchased more than four years before registration cannot be reclaimed, even if the goods are still in stock.

Do I always reclaim the full VAT on a pre-registration asset?

Not necessarily. If you used the asset in the business before registering, HMRC may expect you to apportion the claim and recover only the VAT relating to use after registration. This follows VIT32000 and Revenue and Customs Brief 16 (2016).

Do I need the original VAT invoices?

Yes. HMRC expects valid VAT invoices as evidence of the input tax. Without them, the claim may be disallowed on review.
