Reclaiming VAT on Business Expenses: What You Can and Cannot Claim

Did you know that over 80% of UK VAT-registered businesses reclaim input VAT on their business expenses to improve cash flow and reduce costs? Understanding exactly what VAT you can and cannot reclaim is crucial for small business owners to avoid costly errors and stay compliant with HMRC rules.

Understanding Input VAT and How It Works

Value Added Tax (VAT) is a tax charged on most goods and services sold in the UK. When your business is VAT-registered, you can reclaim the VAT you pay on purchases made for business use — this is known as input VAT. The reclaim process essentially allows you to offset the VAT you have paid against the VAT you charge on sales (output VAT), reducing your overall VAT bill.

However, not all expenses qualify for VAT reclaim. HMRC's rules specify which costs are allowable and which are blocked or partially exempt. The key principle is that VAT can only be reclaimed on costs that are wholly and exclusively for business purposes.

What Expenses Qualify for VAT Reclaim?

Generally, you can reclaim VAT on goods and services purchased for use in your business. This includes office supplies, raw materials, business equipment, and professional services like accountancy fees. Travel expenses such as train tickets or business flights also usually qualify, provided they are strictly for business use.

It’s important to keep detailed and accurate VAT invoices for all purchases you intend to reclaim VAT on. HMRC requires valid VAT invoices showing the supplier’s VAT registration number, the VAT amount charged, and other key details.

Common Expenses Eligible for VAT Reclaim

• Office equipment and stationery
• Professional fees (e.g., solicitors, accountants)
• Business premises rent and utilities (if VAT charged)
• Business travel costs (excluding entertainment)
• Marketing and advertising services
• Fuel for business vehicles (subject to conditions)

Blocked Input Tax: Expenses You Cannot Reclaim VAT On

HMRC explicitly disallows VAT reclaim on certain categories of expenses, commonly referred to as blocked input tax. These mainly relate to costs that are not considered to be wholly for business purposes or are seen as private or non-business costs.

Common blocked input tax examples include:

• Business entertainment, such as client meals, hospitality, and staff parties
• Personal use items or services
• Motor cars (except in certain limited cases)
• Goods or services used to make exempt supplies

For instance, if you take a client out for lunch, the VAT on that meal cannot be reclaimed. Similarly, VAT on private mobile phone bills or household expenses is blocked.

Partial Exemption and Apportioning VAT for Mixed-Use Expenses

If your business makes both VAT taxable and exempt supplies, you are classed as partially exempt. This means you cannot reclaim all the VAT you pay on your purchases. Instead, you must apportion the input VAT based on how much of your business activity is taxable versus exempt.

Partial exemption rules are complex, and HMRC requires businesses to use a reasonable method to apportion VAT. One common approach is to allocate VAT based on turnover proportions or usage estimates.

How to Calculate Partial VAT Reclaim

1. Identify total input VAT paid on purchases.
2. Calculate the percentage of your turnover that is VAT taxable.
3. Apply this percentage to the input VAT to determine the reclaimable amount.
4. Keep records supporting your calculations for HMRC inspections.

For example, if 75% of your turnover is VAT taxable, you can typically reclaim 75% of your input VAT.

Special Rules for Vehicles and Fuel VAT Reclaim

One of the trickiest areas for VAT reclaim is motor vehicles. Generally, VAT on cars is blocked unless the vehicle is used exclusively for business purposes and not available for private use. This includes company cars where employees do not have private use rights.

For fuel, if the vehicle is used only for business, you can reclaim VAT on fuel purchases. However, if there is any private use, you must apply an apportionment or use HMRC’s fuel scale charges.

HMRC provides detailed guidance on motor vehicle VAT reclaim in VAT on motor vehicles.

How to Claim VAT on Business Expenses: Practical Steps

To reclaim VAT correctly and efficiently, follow these practical steps:

• Register for VAT: Ensure your business is VAT-registered with HMRC if your taxable turnover exceeds £85,000 (2026/26 threshold).
• Collect valid VAT invoices: Always get proper VAT invoices from suppliers showing VAT registration numbers and VAT amounts.
• Keep detailed records: Maintain accurate bookkeeping records of all purchases, expenses, and VAT paid.
• Check VAT status: Confirm which expenses qualify for VAT reclaim and which are blocked input tax.
• Apportion VAT where necessary: For partially exempt businesses or mixed-use items, calculate the reclaimable VAT proportion.
• Include input VAT on your VAT Return: Complete your VAT return via HMRC’s online portal, ensuring you claim only eligible VAT amounts.
• Review and retain evidence: Keep all invoices and calculations for at least six years in case of HMRC inspection.
