Do you have to pay tax on business grants?

A grant does not have to be repaid, but that does not make it tax-free. Most UK business grants count as taxable income: a limited company includes them in its profits for Corporation Tax, and a sole trader declares them through Self Assessment. The grant belongs in your accounts for the period in which you become entitled to it — not necessarily the period in which the cash lands.

The main exceptions and wrinkles

• Capital grants — money awarded to fund the purchase of assets — may be treated differently and can sometimes be spread over the life of the asset rather than taxed in one year.
• Covid-era support such as SEISS and CJRS was specifically confirmed as taxable by HMRC, so if you are catching up on old returns, those payments must be included.
• A small number of schemes state their own tax treatment — read the grant agreement, and where it is silent, assume taxable.

Because the grant is income, it can also nudge you across tax thresholds in the year you receive it, so factor it into your cash flow planning rather than treating the full amount as spendable.

Conditions matter as much as tax

Remember that most grants come with strict conditions on how the money is spent and what you must report. Spending on ineligible items, missing agreed milestones, or misrepresenting your business can trigger clawback — repaying some or all of the grant, sometimes with interest or penalties. Keep the grant agreement, your claims, and receipts for eligible expenditure with your business records, and note that many schemes pay in arrears (often 4–12 weeks after approval, sometimes on quarterly claim cycles), which affects when the income arises.

If you are unsure how a specific grant should appear in your accounts — particularly a mixed grant-and-loan award or a capital grant — ask your accountant before you file, not after HMRC asks the question.
