HMRC penalties for VAT return errors

Yes, HMRC can impose penalties for errors in VAT returns, but the nature and severity of the penalty depends heavily on the type of error and your behaviour when the error was made.

The legal framework:

The main provisions are found in Schedule 24 to the Finance Act 2007, which covers penalties for errors in returns and other documents, including VAT returns.

Types of error and penalty ranges:

HMRC classifies errors according to the behaviour that led to the mistake. The penalty is calculated as a percentage of the "potential lost revenue," meaning the additional tax that would have been due had the return been correct.

1. Careless errors. These are mistakes caused by a failure to take reasonable care. The penalty range is 0 to 30 per cent of the potential lost revenue.

2. Deliberate but not concealed errors. Where you knowingly submitted an incorrect return but did not take active steps to hide the inaccuracy. The penalty range is 20 to 70 per cent.

3. Deliberate and concealed errors. Where you knowingly submitted an incorrect return and took steps to hide the inaccuracy. The penalty range is 30 to 100 per cent.

Genuine mistakes:

If the error is genuinely accidental and you took reasonable care when preparing the return, HMRC should not impose a penalty at all. This is sometimes called a "reasonable care" defence. What counts as reasonable care depends on the circumstances, including the complexity of the issue, whether you sought advice, and the systems you had in place for preparing returns.

Unprompted versus prompted disclosure:

The penalty ranges above have lower and upper limits. Where you fall within the range depends largely on whether you told HMRC about the error yourself (an unprompted disclosure) or whether HMRC discovered it (a prompted disclosure). Unprompted disclosures attract significantly lower penalties. HMRC also considers the quality of your disclosure, looking at three elements: telling them about the error, helping them quantify the error, and giving them access to relevant records.

Error correction thresholds:

There is a separate mechanism for correcting errors on a later VAT return rather than making a separate disclosure to HMRC. Under the VAT Regulations 1995, you can adjust a later return if the net error is no more than £10,000, or if it is between £10,000 and £50,000 and does not exceed one per cent of your box 6 figure (net outputs) for the return period in which you are making the correction. Errors above these thresholds must be notified to HMRC separately using form VAT652 or by letter.

Interest:

Regardless of penalties, HMRC will charge interest on any underpaid VAT from the date it was originally due until the date it is paid.

Suspension of penalties:

For careless errors, HMRC has the power to suspend a penalty for up to two years, subject to conditions. If you comply with the conditions during the suspension period, the penalty is cancelled. This is a useful mechanism to be aware of if HMRC is considering a penalty.

Time limits:

HMRC generally has four years from the end of the relevant VAT period to assess additional VAT for careless errors. For deliberate errors, the time limit extends to 20 years.

Practical points:

If you have discovered an error, it is almost always better to tell HMRC yourself promptly rather than wait for them to find it. An unprompted disclosure will reduce any penalty substantially and demonstrates good faith.

If HMRC has already raised a penalty and you believe the error was made despite taking reasonable care, you can challenge the penalty by asking HMRC for a review and, if necessary, appealing to the First-tier Tribunal (Tax Chamber). You do not need to pay the penalty before appealing, although interest may continue to accrue on any underlying tax due.

Keep thorough records of how you prepare your VAT returns, any advice you took, and any systems or checks you have in place. These are directly relevant to demonstrating reasonable care if a question ever arises.
