Frequently Asked Questions

How does the new VAT penalty regime work?

From January 2023, HMRC replaced the old surcharge with a new system: 2% penalty after 15 days, a further 2% after 30 days, then a daily rate of 4% per annum from day 31. Late payment interest at Bank Rate + 2.5% also applies from day one.

Is there a grace period for VAT late payment?

No penalty is charged if you pay within 15 days of the due date. HMRC also has a period of familiarisation for businesses adjusting to the new rules.

What is a Time to Pay arrangement?

A TTP arrangement lets you pay VAT in instalments. Penalties stop accruing once agreed, though interest continues. Call HMRC on 0300 200 3835 before the due date.

How do I appeal a VAT penalty?

Appeal within 30 days using form VAT484 or your HMRC online account if you have a reasonable excuse such as serious illness or an unexpected event outside your control.

What is late payment interest on VAT?

Interest accrues from the day after the due date at Bank of England base rate plus 2.5%, calculated daily on the unpaid amount until cleared.

What replaced the old VAT default surcharge?

The old surcharge was replaced from January 2023 with a points-based late filing system and the new late payment penalty regime, designed to be fairer for occasional late filers.

Can HMRC reduce a VAT penalty?

Yes, where there is a reasonable excuse, a full voluntary disclosure, or during the familiarisation period. Co-operation with HMRC enquiries can also reduce penalties.

What happens if I file my VAT return late?

Each late return earns a penalty point. Reaching the threshold (4 points for quarterly, 5 for monthly, 2 for annual filers) triggers a £200 fixed penalty. Points expire after 24 months of full compliance.

Does the penalty apply to all VAT-registered businesses?

Yes, for all VAT returns for periods starting on or after 1 January 2023, including standard and annual accounting schemes.

What is the penalty for an inaccurate VAT return?

Penalties range from 0% to 100% of lost tax: careless errors up to 30%, deliberate up to 70%, deliberate and concealed up to 100%. Lower rates apply for unprompted disclosures.

How is the daily penalty rate calculated?

4% per annum divided by 365 = approximately 0.01096% per day of the outstanding VAT amount, from day 31 until the debt is cleared.

What if I cannot afford to pay my VAT bill?

Contact HMRC as soon as possible to discuss a Time to Pay arrangement before the due date. HMRC generally prefers to agree a payment plan over enforcement action.
