Reclaiming VAT on Business Expenses

Most VAT-registered businesses leave money on the table by not knowing exactly what's reclaimable. The other half over-claim and find out the hard way during a compliance check. Here's the rulebook.

What input VAT actually is

Input VAT is the VAT a VAT-registered business pays on its purchases. Most input VAT can be reclaimed from HMRC by including it in Box 4 of your VAT return, reducing the net VAT you owe.

The general rule is: if (a) the supply is taxable (standard, reduced or zero-rated, not exempt), (b) you have a valid VAT invoice, and (c) the cost is incurred wholly or mainly for taxable business activities — you can reclaim. Outside that, there are blocks, restrictions and apportionments.

What makes a valid VAT invoice

You can only reclaim VAT if you hold an invoice that meets HMRC's requirements. A full VAT invoice must show:

• The supplier's name, address and VAT number
• A unique sequential invoice number
• The date of issue and the time of supply (tax point) if different
• The customer's name and address
• A description of the goods or services
• For each item: quantity, unit price, VAT rate applied, total amount net of VAT
• The total VAT amount and the gross total

Receipts under £250 (gross) qualify as "less detailed VAT invoices" — they only need supplier name + VAT number, date, description, gross total and VAT rate. Most petrol receipts are this format.

What you cannot reclaim — the headline blocks

• Business entertainment for non-employees (clients, suppliers, prospects). Almost always blocked. See section below.
• Cars — VAT on the purchase of a car is blocked unless the car is "exclusively for business" (no private use whatsoever). Almost no employee or director cars meet this test.
• Goods sold under the Margin Schemes (e.g. second-hand goods, antiques) — the VAT is calculated differently.
• Goods or services for personal use — apportion if mixed.
• Costs related to exempt supplies — if your business has exempt income (insurance, financial services, education, healthcare), you may need to apply partial exemption rules.
• Costs of buying a non-business asset — e.g. residential property letting (residential rents are exempt).

The entertainment block — what's allowed and what isn't

Business entertainment is one of the most-misunderstood areas. The general rule: VAT on entertaining non-employees is blocked. But there are nuances.

The "subsistence" allowance for travelling employees is the main legitimate route to reclaim food and drink. The cost must be reasonable and the employee must be away from their normal place of work.

Cars, fuel and travel

Buying a car

VAT on a new car is fully blocked unless the car is used exclusively for business. HMRC interprets "exclusively" strictly — a car kept overnight at the home of an employee or director virtually never qualifies, because that is itself private use.

Vans and commercial vehicles don't have this block. The VAT on a van purchase is fully reclaimable if it's used for business.

Leasing a car

For lease cars used partly privately, you can reclaim 50% of the VAT on the lease payments. This is a fixed flat-rate adjustment regardless of actual private use percentage. Maintenance and breakdown cover element on the lease is fully reclaimable.

Fuel

You have three options for car fuel costs with private use:

• Reclaim all VAT, pay a fuel scale charge — HMRC publishes a per-period fuel scale charge based on CO₂ emissions. You add this to Box 1.
• Reclaim only business mileage VAT — keep detailed mileage records and apportion.
• Reclaim no VAT on fuel — simpler if private use is high.

For a typical company car the fuel scale charge route is the simplest. HMRC publishes the rates each tax year.

Other travel

• Train and bus fares are zero-rated, so there's no VAT to reclaim
• UK air travel is zero-rated
• Taxis: VAT only reclaimable if the driver is VAT-registered (most aren't)
• Hotel accommodation: standard rated, fully reclaimable for business trips

Mixed business / personal use — apportionment

If a cost is partly business and partly personal, you reclaim the business proportion. Common examples:

• Mobile phone — apportion by usage. 80% business / 20% personal is a common starting point but document the method.
• Home office expenses — apportion by floor area or hours. The 25%-of-bills rule from income tax doesn't apply for VAT; you need a defensible method.
• Vehicles other than cars — log book showing business vs private mileage, reclaim the business %.

HMRC accepts any reasonable, consistently-applied method. Keep the method documented; if HMRC asks, "I just guessed" doesn't fly.

Pre-registration VAT — the often-missed claim

Your first VAT return is the only one where you can reach back into expenses incurred before you were registered. Two time limits apply:

• Goods — VAT on goods bought up to 4 years before registration is reclaimable, provided the goods are still on hand at the registration date. Examples: stock, equipment, fixtures.
• Services — VAT on services received up to 6 months before registration is reclaimable. Examples: legal fees, accountancy, software subscriptions, setup costs.

Document each item: original invoice, supplier VAT number, amount, date. List them on a schedule that ties to your first VAT return Box 4. Don't bury them inside the period's normal Box 4.

Imports and postponed VAT accounting

Since 1 January 2021, UK VAT-registered importers can use Postponed VAT Accounting (PVA). Instead of paying import VAT at the border and reclaiming later, you account for the import VAT on your VAT return as both an input and an output, in the same period. The net cash effect is zero — but you preserve cashflow.

You don't need to apply for PVA — you elect to use it on each import declaration. Most freight forwarders default to PVA. You then download a Monthly Postponed Import VAT Statement (MPIVS) from HMRC's CDS portal, which shows the VAT to put in Box 1 (output) and Box 4 (input).

Five mistakes that trigger HMRC compliance checks

1. Reclaiming on a non-VAT receipt

If a £30 receipt has no VAT number on it (e.g. a small supplier under the threshold, or a foreign supplier), you cannot reclaim. Adding it anyway is a flag.

2. Round numbers

Suspiciously rounded Box 4 values trigger algorithmic flags. £450.00, £1,200.00, £600.00 all in one return looks made-up. Real input VAT is rarely round.

3. Box 7 inconsistent with industry norm

If your Box 7 (purchases ex VAT) is higher than your Box 6 (sales ex VAT) for several quarters in a row and you're not in start-up phase, HMRC's risk algorithms will look at you. This is normal during heavy investment, but expect the question.

4. Reclaiming on staff entertainment that's actually client entertainment

The temptation is to recategorise. HMRC's investigators read the calendar invites, the photos on social media, and ask the staff. If the lunch was really with a client, the VAT was blocked.

5. Reclaiming home office VAT without a method

Director-only companies often reclaim a chunk of utility VAT as "home office". Fine — if you have a method (e.g. one room out of six = 16.7%) and apply it consistently. "Roughly a third" written nowhere is not a method.

FAQ

Can I reclaim VAT on capital expenditure over £2,000 if I'm on the Flat Rate Scheme?

Yes. This is the only input VAT reclaim allowed under FRS — capital goods over £2,000 inc-VAT on a single invoice. See our Flat Rate Scheme guide.

I lost an invoice. Can I still reclaim?

HMRC has discretion. You can ask the supplier for a duplicate (preferred). Failing that, you can claim with alternative evidence (bank statement, contract, email confirmation) but HMRC isn't obliged to allow it. Ask before claiming.

Can I reclaim VAT on training courses for staff?

Yes — staff training related to current or future job role is reclaimable. Personal development courses unrelated to the job are not.

How long do I keep VAT records?

Six years from the end of the relevant VAT period, in line with HMRC's general record-keeping requirement.
