VAT Return Deadlines: Penalties, Surcharges & How to Appeal

The New VAT Penalty Regime: What Changed in January 2023

HMRC replaced the old VAT default surcharge system with a new points-based late submission penalty regime for VAT periods starting on or after 1 January 2023. If you're still mentally working under the old rules, it's time to update your understanding — the mechanics are quite different.

How the Points-Based System Works

Every time you submit a VAT return late, HMRC adds one penalty point to your account. Points accumulate over time, and once you hit a set threshold, you receive a £200 financial penalty. You then receive a further £200 penalty for every subsequent late submission while you remain at or above the threshold.

The threshold depends on how frequently you submit VAT returns:

• Annual filers: Threshold of 2 points
• Quarterly filers: Threshold of 4 points
• Monthly filers: Threshold of 5 points

Points expire after 24 months if you remain below the threshold, but once you've hit the threshold, your points only reset to zero after you've submitted all returns on time for a set compliance period — 24 months for annual filers, 12 months for quarterly filers, and 6 months for monthly filers.

Late Payment Penalties: A Separate Issue

Late submission penalties are separate from late payment penalties. If you pay your VAT bill late, HMRC charges:

• 2% of the outstanding VAT if paid between 16 and 30 days late
• 4% of the outstanding VAT if still unpaid after 30 days
• A further daily rate of 4% per annum on the outstanding balance after 31 days

HMRC also charges late payment interest at the Bank of England base rate plus 2.5%, calculated from the payment due date. As of August 2026, with the base rate at 4.25%, that means an effective interest rate of 6.75% per annum.

Reasonable Excuse: Your First Line of Defence

If you've received a penalty, don't simply accept it. HMRC allows you to appeal on the grounds of reasonable excuse — a genuine, unexpected event that prevented you from filing or paying on time. Accepted examples include:

• Serious illness or bereavement affecting you or a close family member
• An unexpected IT failure at HMRC or your accountancy software
• A fire, flood, or other unforeseen disaster disrupting your records
• Postal delays causing a critical document not to arrive in time

Importantly, lack of funds alone is not a reasonable excuse, nor is relying on an agent who failed to act — although it may reduce culpability in some circumstances.

How to Appeal a VAT Penalty

You have 30 days from the date of the penalty notice to appeal. Here's how to do it:

• Log into your HMRC online account and navigate to your VAT account to submit an appeal digitally — this is the fastest method
• Alternatively, write to HMRC VAT Compliance at the address on your penalty notice, clearly stating your VAT registration number, the penalty reference, and your grounds for appeal
• If HMRC rejects your appeal, you can escalate to the First-tier Tax Tribunal, which is independent of HMRC

Keep written records of everything — correspondence, software screenshots, medical certificates — as evidence strengthens your case significantly.

Practical Steps to Avoid Penalties Altogether

Prevention is always better than cure. Set calendar reminders one month before each VAT return deadline. If you file quarterly, your due dates are typically one calendar month and seven days after the end of each VAT period. Consider using Making Tax Digital (MTD)-compatible software such as QuickBooks, Xero, or FreeAgent, which can automate submissions and flag upcoming deadlines so you're never caught off guard.
