UK VAT Partial Exemption Explained 2026: A Practical Guide for Mixed Businesses

VAT partial exemption is one of the most complex areas of UK tax compliance. It catches businesses that make a mix of VAT-taxable and VAT-exempt supplies, limiting their ability to recover input VAT in full. Get it wrong and HMRC can assess you for years of under-declared VAT, plus interest and penalties.

Who Is Caught by Partial Exemption?

A business is partially exempt whenever it makes exempt supplies alongside taxable ones. Common exempt supplies include:

• Financial services (lending, insurance intermediation)
• Residential property lettings
• Education and vocational training (in certain circumstances)
• Health and welfare services
• Burial and cremation services

Businesses making only taxable supplies (including zero-rated ones) are not partially exempt and can reclaim all input VAT in the usual way.

The Standard Method: How It Works

Unless HMRC approves a special method, partially exempt businesses must use the standard method to calculate what proportion of their input VAT is recoverable.

The formula is:

Recovery percentage = (Taxable turnover / Total turnover) x 100

This percentage is then applied to the input VAT that cannot be directly attributed to either taxable or exempt supplies -- the so-called residual input tax.

Worked Example

Imagine a financial consultancy with 2026/27 figures:

• Taxable advisory fees: GBP 300,000
• Exempt insurance commission: GBP 100,000
• Total turnover: GBP 400,000

Recovery percentage = 300,000 / 400,000 = 75%

If the firm incurs GBP 40,000 of residual input VAT (e.g., on rent, IT, professional subscriptions), it can recover 75% = GBP 30,000. The remaining GBP 10,000 becomes an irrecoverable business cost.

Input VAT that is directly attributable to taxable supplies is fully recoverable; input VAT directly attributable to exempt supplies is blocked entirely. Only residual costs go through the percentage calculation.

The De Minimis Rule: A Useful Escape Hatch

If your blocked (exempt) input tax is small, you may qualify for de minimis treatment and recover everything:

• Exempt input tax must not exceed GBP 625 per month on average (GBP 7,500 per year), and
• Exempt input tax must not exceed 50% of total input tax

Both tests must be passed. A business just below GBP 7,500 in blocked input tax can claim it all back, simplifying administration considerably. Review your position at the end of each tax year (and optionally each VAT period) -- falling in or out of de minimis should trigger a change in how you treat costs.

Special Methods: When the Standard Method Is Unfair

The standard method uses turnover as a proxy for use, but turnover does not always reflect reality. A property management company might earn modest fees on exempt residential lettings but incur enormous overheads serving commercial (taxable) tenants. Turnover would understate the true recovery position.

In these cases you can apply to HMRC for a special method that better reflects economic reality. Common alternatives include:

• Transaction count -- useful for financial services with many low-value exempt transactions
• Floor area -- used when premises serve mixed activities
• Staff headcount -- appropriate when labour rather than turnover drives costs
• Income minus certain supplies -- used when specific large supplies distort turnover proportions

HMRC must approve any special method before it is used. Submitting a VAT 602 application requires detailed justification showing why the standard method gives an unfair or unreasonable result.

The Annual Adjustment

Even if you calculate partial exemption quarterly, you must carry out an annual adjustment using the full-year figures. This corrects for any over- or under-recovery during the year.

The annual adjustment is included on the return for the period that covers the end of your partial exemption year (usually 31 March, 30 April, or 31 May depending on your VAT return stagger). Significant adjustments -- either repayments or additional liabilities -- can come as a surprise if you have not tracked your position throughout the year.

Capital Goods Scheme

If you purchase capital items above certain thresholds (GBP 50,000 for computers and items, GBP 250,000 for land and buildings), partial exemption does not end at purchase. The Capital Goods Scheme requires you to review and potentially adjust the VAT recovery over a period of five or ten years based on your actual taxable/exempt use in each year. This is particularly relevant for businesses that acquire commercial property.

Practical Tips for 2026

1. Classify costs correctly from the start. Distinguish direct taxable, direct exempt, and residual costs as invoices arrive rather than trying to reconstruct the split at year end.
2. Review the de minimis position quarterly. If you are close to the threshold, small changes in your cost structure can tip you in or out.
3. Consider a special method early. If the standard method clearly gives a distorted result, apply for a special method as soon as possible -- HMRC approval takes time and the method cannot be applied retrospectively without agreement.
4. Document your methodology. HMRC expects businesses to be able to demonstrate their partial exemption calculation clearly in any compliance check.

Common Mistakes and HMRC Scrutiny

HMRC focuses on partial exemption during VAT inspections because errors are common and the sums involved can be large. Typical errors include:

• Treating all input VAT as recoverable when some supplies are exempt
• Incorrectly classifying supplies as taxable when they are exempt (particularly in property and finance)
• Failing to perform the annual adjustment
• Using the wrong turnover figures (e.g., including VAT in the denominator, or including non-business income)

If HMRC discovers an error, it can assess for up to four years (or 20 years in cases of fraud or deliberate under-declaration).
