You can adjust your current VAT account to correct errors on past returns if they’re:
- below the 'reporting threshold'
- not deliberate; and
- for an accounting period that ended less than 4 years ago
The reporting thresholds that apply are:
- the net value of the errors is £10,000 or less; or
- your error amount is less than 1% of your box 6 figure (up to a maximum of £50,000).
If you do not meet these criteria, you will need to separately disclose these inaccuracies to HMRC using form VAT652. HMRC will then send you a notice telling you if the amount you calculated is correct and any interest or VAT you owe.
Regardless which route you make the correction, you must keep details about the error - for example the date it was discovered, how it happened, the amount of VAT involved - and make an adjustment for them in your VAT account (usually part of your bookkeeping system or year end accounts).
