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:

VAT input tax recovery rules

Rules for reclaiming VAT on business purchases, including evidence requirements, time limits, and proportional recovery for mixed use.

Input tax is the VAT you pay on goods and services purchased for your business. You can reclaim input tax on your VAT return if the purchases are used to make taxable supplies (standard-rated, reduced-rate, or zero-rated sales).

Basic rule: Reclaim VAT on goods and services used wholly for taxable business supplies
Time limit for claiming: 4 years from the due date of the VAT return on which you could first claim
Evidence required: Valid VAT invoice showing supplier's VAT number, date, description, and VAT amount
Minimum invoice threshold: Simplified invoices allowed for supplies up to £250 (including VAT)
Record retention: 6 years for all VAT invoices and records

What you can reclaim

VAT on goods and services used exclusively for taxable business activities
VAT on pre-registration purchases (goods still held at registration, services received within 6 months)
Import VAT (using C79 certificate or Postponed VAT Accounting statement)

What you cannot reclaim (blocked input tax)

Business entertainment (except for overseas customers)
Cars not used wholly for business (unless taxi, driving school, or leased)
Non-business purchases
Items used for exempt supplies

Pre-registration goods: Can reclaim VAT on goods still held at registration date (up to 4 years before)
Pre-registration services: Can reclaim VAT on services received within 6 months before registration
Business entertainment: Blocked - cannot reclaim VAT (except entertaining overseas customers)
Motor cars: Blocked - cannot reclaim unless 100% business use (taxi, driving school, pool car)

Mixed use and partial exemption

If you make both taxable and exempt supplies, you cannot reclaim all your input tax. You must use the partial exemption method to calculate how much you can reclaim.

Standard method: Calculate the proportion of taxable supplies to total supplies (excluding VAT). Apply this percentage to your input tax to find the reclaimable amount.

De minimis limit: If your exempt input tax is both under £625 per month on average AND less than 50% of total input tax, you can reclaim all input tax as if you were fully taxable.

De minimis limit: £625 per month average AND less than 50% of total input tax
Annual adjustment: Required at year end to compare provisional claims with actual use
Alternative methods: Special methods can be agreed with HMRC if standard method is not fair

Capital Goods Scheme

For high-value capital items, you must adjust your input tax claim over several years if the proportion of taxable use changes. This applies to:

Land and buildings costing £250,000 or more (excluding VAT)
Computers and computer equipment costing £50,000 or more (excluding VAT)
Aircraft, ships, boats, and other vessels costing £50,000 or more (excluding VAT)

Land and buildings adjustment period: 10 intervals (years) from first use
Computers/aircraft/ships adjustment period: 5 intervals (years) from first use
Capital goods threshold (land/buildings): £250,000 or more (excluding VAT)
Capital goods threshold (computers/ships/aircraft): £50,000 or more (excluding VAT)

VAT Notice 706 - Partial exemption

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.

VAT purchase records - evidence required

Records and evidence that must be kept to support input tax claims.

To reclaim input VAT on purchases, you must hold valid evidence. Without proper evidence, HMRC can disallow your input tax claim.

Valid VAT invoice: Original invoice from supplier showing their VAT number and breakdown
Import VAT certificate (C79): Monthly certificate from HMRC for import VAT paid (must keep original)
Postponed VAT accounting statement: Monthly statement for imports using PVA
Reverse charge documentation: Evidence of reverse charge applied on services from abroad
Supplier's VAT registration number: Must be valid at time of supply (can verify online)
Business use evidence: Evidence that purchase was for business purposes (not private use)

No invoice available: Cannot reclaim input VAT without valid evidence
Lost invoice: Request duplicate from supplier (must be clearly marked as copy)
Supplier not VAT registered: No VAT to reclaim on purchases from non-VAT-registered suppliers
Invoice missing VAT number: Contact supplier to correct - cannot reclaim without valid number

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:

VAT records retention period - 6 years

How long VAT records must be kept and what happens after deregistration.

Standard retention period: 6 years from date of transaction or invoice
EPOS/till rolls: 6 years (4 years with HMRC concession if summary retained)
Electronic records: 6 years in accessible and readable format
After deregistration: 6 years from date of transaction (same as when registered)
Company dissolution exception: 12 months from date of company dissolution (for liquidators)
HMRC enquiry: Must retain longer if enquiry or dispute is ongoing

The 6-year period runs from the date of the transaction or invoice, not from the end of the VAT period or accounting year. If HMRC opens an enquiry, you must retain records until the enquiry is concluded, even if this exceeds 6 years.

VAT invoice retention requirements

How long VAT invoices must be kept and storage requirements.

Standard retention period: 6 years from the date of issue
Sales invoices issued: Must retain copies of all VAT invoices issued
Purchase invoices received: Must retain originals of all VAT invoices received (to support input tax claims)
Format of retention: Paper or electronic (electronic must be readily accessible and legible)
Credit notes: Must retain for 6 years (both issued and received)
Debit notes: Must retain for 6 years
After deregistration: Must retain records for 6 years after deregistration

HMRC may request copies of invoices during a VAT inspection or enquiry. Failure to produce invoices can result in input tax claims being disallowed and penalties for inadequate records.

VAT guide (VAT Notice 700)

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:

Your exempt input tax averages less than £625 per month, AND
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.

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.
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.
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.
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.
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.
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 form VAT652.

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