When you're VAT registered, you can reclaim the VAT you pay on goods and services bought for your business. This is called input tax. Reclaiming input tax reduces your VAT bill or, if you reclaim more than you owe, results in a refund from HMRC.

However, not all VAT can be reclaimed. You must meet specific conditions, keep proper evidence, and understand which purchases are blocked from recovery. This guide explains the rules so you can maximise your legitimate VAT recovery while staying compliant.

Input tax recovery rules

The basic rules for reclaiming VAT on purchases:

Evidence you need to reclaim VAT

HMRC can disallow any input tax claim where you cannot produce valid evidence. The most important requirement is a valid VAT invoice from your supplier.

What makes a VAT invoice valid

For purchases over £250 (including VAT), you need a full VAT invoice containing 14 mandatory items. For smaller purchases, a simplified invoice is acceptable. Key information that must appear on any VAT invoice:

  • Supplier's name, address, and VAT registration number
  • Date of supply (tax point)
  • Description of goods or services
  • Total amount and VAT charged

If an invoice is missing the supplier's VAT number, you cannot reclaim the VAT until you obtain a corrected invoice.

How long to keep VAT records

You must retain all VAT invoices and supporting records:

Time limit for reclaiming VAT

You have 4 years from the due date of the VAT return on which you could first have claimed the input tax. After this deadline, the claim is time-barred and you lose the right to recover that VAT.

Standard time limit
4 years from the due date of the relevant VAT return
Practical tip
Claim VAT on the return for the period in which you receive the invoice
Missed claim recovery
Can adjust on a later VAT return within the 4-year window
Late registration
Still subject to 4-year rule from when claim could first have been made

What you can reclaim VAT on

You can reclaim VAT on goods and services that are used wholly and exclusively for making taxable supplies. This includes:

  • Stock and materials - goods you buy to sell or use in production
  • Business overheads - rent, utilities, professional fees, office supplies
  • Equipment and tools - machinery, computers, furniture used in the business
  • Commercial vehicles - vans, lorries (but not most cars - see blocked input tax)
  • Marketing and advertising - including website costs
  • Travel and subsistence - for business purposes (excluding entertainment)
  • Import VAT - using your C79 certificate or Postponed VAT Accounting statement

What you cannot reclaim (blocked input tax)

Some VAT is legally blocked from recovery, regardless of whether the purchase was for business purposes. You can never reclaim VAT on these items:

Business entertainment
Cannot reclaim VAT on entertaining clients, customers, or suppliers (except overseas customers)
Motor cars
Cannot reclaim VAT on cars unless 100% business use (taxi, driving school, pool car with no private use)
Non-business purchases
Personal or private purchases are not input tax
Items used for exempt supplies
If you use the item to make exempt supplies, no VAT recovery

Business entertainment explained

VAT on entertaining UK customers, suppliers, or business contacts is blocked - even if the entertainment serves a genuine business purpose. However, you can reclaim VAT on:

  • Entertaining overseas customers (not UK residents)
  • Staff entertainment (Christmas parties, team events) - but only if open to all staff, not just directors
  • Entertaining employees who are not directors or partners

Motor cars

You generally cannot reclaim VAT when buying or leasing a car because cars typically have some private use. Exceptions where you CAN reclaim:

  • Cars used 100% for business - taxi, driving school, car hire, or genuine pool car with no private use
  • 50% of the VAT on a leased car (not purchased) - this accounts for potential private use
  • Commercial vehicles (vans, lorries) - fully reclaimable

Reclaiming VAT before you registered

When you register for VAT, you can claim back VAT you paid before registration - if you still hold the goods or benefited from the services for your taxable business. This is often called pre-registration input tax.

Goods still held at registration
Can reclaim VAT on goods you still have when you register (up to 4 years before)
Services
Can reclaim VAT on services received within 6 months before registration
Key requirement
The goods or services must relate to your taxable business supplies
Example - stock
Reclaim VAT on unsold stock purchased before registration
Example - equipment
Reclaim VAT on computer bought 18 months before registration (if still used)

Important: You cannot reclaim pre-registration VAT on goods you've already sold or consumed before registration. The goods must still be in your possession as assets or stock.

Partial exemption: mixed taxable and exempt supplies

If your business makes both taxable supplies (where you charge VAT) and exempt supplies (where you don't charge VAT), you cannot reclaim all your input tax. You must use a partial exemption calculation to work out how much you can recover.

Common examples of exempt supplies:

  • Insurance
  • Finance and credit
  • Education and training (in some circumstances)
  • Healthcare
  • Betting and gambling
  • Letting residential property
Standard method
Calculate proportion of taxable supplies to total supplies; apply percentage to input tax
De minimis limit
If exempt input tax is under £625/month average AND under 50% of total input tax, reclaim all
Annual adjustment
Must recalculate at year end based on actual use
Special methods
Can agree a different calculation method with HMRC if standard method isn't fair

De minimis exemption

If your exempt input tax is relatively small, you may be able to treat yourself as fully taxable and reclaim all input tax. You qualify for de minimis treatment if:

  1. Your exempt input tax averages less than £625 per month, AND
  2. Your exempt input tax is less than 50% of your total input tax

Both conditions must be met. If you qualify, you can reclaim all your input tax as if you only made taxable supplies.

If your situation is more complex, or your exempt supplies are significant, consult an accountant or VAT specialist to ensure you're calculating recovery correctly.

How to reclaim VAT on your return

You reclaim input tax through your regular VAT return. The process is straightforward if you keep good records.

  1. 1

    Record VAT on all eligible purchases

    Use MTD-compatible software to record the VAT amount shown on each supplier invoice. Only record VAT where you hold a valid VAT invoice.

  2. 2

    Identify any blocked or exempt items

    Mark purchases where VAT cannot be reclaimed (entertainment, cars, exempt-related costs). Do not include these in your input tax total.

  3. 3

    Calculate partial exemption if applicable

    If you make exempt supplies, apply your partial exemption method to work out reclaimable VAT. Keep working papers to support your calculation.

  4. 4

    Enter input tax in Box 4 of VAT return

    Box 4 shows 'VAT reclaimed on purchases and other inputs'. Enter your total reclaimable VAT here.

  5. 5

    Check net position

    Box 5 shows the difference between VAT you owe (Box 3) and VAT you reclaim (Box 4). If Box 4 is larger, HMRC will refund the difference.

  6. 6

    Keep all records for 6 years

    Retain invoices, calculations, and workings. HMRC can enquire into any claim within 4 years.

Common mistakes to avoid

HMRC regularly finds errors in input tax claims. Avoid these common problems:

  • Missing or invalid invoices - claiming VAT without proper evidence. Always check invoices include the supplier's VAT number.
  • Claiming blocked items - entertainment and car VAT are frequently claimed in error.
  • Forgetting partial exemption - if you make any exempt supplies, you must apply partial exemption rules.
  • Wrong tax period - claim VAT in the period you receive the invoice (or the period you make the payment, if using Cash Accounting).
  • Supplier not VAT registered - if your supplier isn't VAT registered, there's no VAT to reclaim (the charge isn't VAT).
  • Claiming VAT on deposits - only claim when you receive a VAT invoice, not when you pay a deposit.
  • Private use element - if an item has both business and personal use, you can only reclaim the business proportion.

Correcting errors

If you discover you've overclaimed or underclaimed input tax, you can correct errors on your next VAT return if:

  • The net error is £10,000 or less, OR
  • The net error is between £10,000 and £50,000 and is less than 1% of your Box 6 turnover

Simply adjust your Box 4 figure on the next return. For larger errors, or if you prefer, you can report to HMRC using the online error correction service.

Voluntary disclosure of errors often results in reduced penalties if HMRC would have found the error themselves.
