VAT Penalties Guide: The New Points-Based System Explained
From Default Surcharge to Points — What Changed?
The old default surcharge regime, in place since 1987, charged an escalating percentage penalty (2%, 5%, 10%, 15%) if you paid VAT late more than once in a rolling 12-month period. It was widely criticised for being disproportionate, particularly for businesses that were only a few days late with small amounts. The new regime, effective from 1 January 2023 for all VAT-registered businesses, separates late submission penalties from late payment penalties and introduces a more proportionate framework.
HMRC's stated policy intent was to ensure penalties "encourage rather than punish" — the new system gives businesses a 15-day grace period for payment, uses points for submission lateness (like penalty points on a driving licence), and replaces percentage surcharges with flat penalties plus daily accrual interest. HMRC operated a "period of familiarisation" from January 2023 to April 2024, during which no first £200 submission penalties were issued.
Late Submission Penalties: How Points Accumulate
Every late VAT return submission earns one penalty point. Points have a threshold that depends on your filing frequency:
| Filing Frequency | Point Threshold for £200 Penalty | Point Expiry Period | Compliance Reset Period |
|---|---|---|---|
| Monthly | 5 points | 25 months | 6 consecutive on-time returns |
| Quarterly | 4 points | 24 months | 4 consecutive on-time returns (12 months) |
| Annual | 2 points | 25 months | 2 consecutive on-time returns (24 months) |
Once you reach the threshold, a £200 penalty is issued for that return and for every subsequent late return until your points are reset. Points are reset when you file all returns on time for the compliance reset period AND have no outstanding late returns from the previous 24 months.
Points automatically expire after the expiry period if you have not reached the threshold. However, once the threshold is crossed and you are in the penalty zone, points do not automatically expire — you must meet the compliance criteria.
Late Payment Penalties: Three-Stage Process
The late payment penalty regime works on a stepped basis:
- Days 1–15: No penalty. Pay in full and no late payment penalty is charged at all.
- Day 16: First late payment penalty triggered. Initially calculated at 2% of the VAT outstanding at day 15.
- Day 31: First penalty increases. Recalculated at 4% of the VAT outstanding at day 30.
- Day 31 onwards: Second late payment penalty begins. Charged at 4% per annum (daily rate = 4%/365), calculated on the outstanding balance each day from day 31 until payment.
Note: if a Time to Pay arrangement is agreed before the due date, no late payment penalties apply to amounts covered by the arrangement (provided payments are made on time). Late payment interest continues to accrue even during TTP.
Late Payment Interest Rate
HMRC charges late payment interest from the day after the payment due date until the day before payment is received. The rate is the Bank of England base rate plus 2.5%. With the Bank Rate at 4.5% as of March 2026, the current HMRC interest rate is 7.0% per annum. This is set in legislation and changes automatically when the Bank Rate changes.
HMRC also pays repayment interest when it owes money to businesses (e.g. VAT repayment claims), set at Bank Rate minus 1% (minimum 0.5%). The asymmetry between rates charged (7.0%) and rates paid (3.5%) reflects the cost of HMRC debt management. Interest amounts under £25 for a single period are not charged in practice.
Worked Example: £10,000 VAT Unpaid for 60 Days
Scenario: £10,000 VAT due, filed on time but paid 60 days late. BoE rate 4.5%.
| Item | Amount |
| VAT outstanding at day 15 | £10,000 |
| VAT outstanding at day 30 | £10,000 |
| First late payment penalty (4% of £10,000) | £400.00 |
| Second penalty (4%/365 × 30 days × £10,000) | £32.88 |
| Late payment interest (7.0%/365 × 60 days × £10,000) | £115.07 |
| Total Additional Cost | £547.95 |
Making Tax Digital (MTD) for VAT
MTD for VAT has been mandatory for all VAT-registered businesses since April 2022. Under MTD, businesses must:
- Keep digital VAT records using compatible software
- File VAT returns directly from software via HMRC's API — paper returns are no longer accepted
- Maintain a complete digital audit trail linking source transactions to VAT return figures
Failure to comply with MTD rules can result in separate penalties under the MTD compliance regime, independent of the late payment and submission penalties. HMRC can issue up to £400 per return period for non-MTD-compliant filing. MTD for Income Tax (for self-employed and landlords with income over £50,000) begins from April 2026, and for those with income over £30,000 from April 2027.
Old Default Surcharge vs New Penalty Regime
| Feature | Old Default Surcharge (pre-2023) | New Penalty Regime (from Jan 2023) |
|---|---|---|
| First late payment | Surcharge notice only (no financial penalty) | No penalty if paid within 15 days |
| Second late payment | 2% of VAT outstanding | 2% if 16–30 days; 4% if 31+ days |
| Subsequent late | 5%, 10%, 15% escalating | Flat 4% first penalty + daily second penalty |
| Interest | No separate late payment interest | BoE base rate + 2.5%, daily from day 1 |
| Late submission | Part of default surcharge | Separate points system; £200 per threshold breach |
| De minimis | No surcharge if VAT < £400 | Interest not charged if < £25 |
Appealing VAT Penalties
You can appeal a VAT penalty if you believe HMRC has made an error or you have a reasonable excuse. The appeal process:
- Step 1 — Request a review: Contact HMRC within 30 days of the penalty notice. HMRC must review within 45 days.
- Step 2 — HMRC review: An independent HMRC officer reviews the decision. They can uphold, vary, or cancel the penalty.
- Step 3 — First-tier Tribunal: If unsatisfied with the review outcome, you can appeal to the Tax Chamber of the First-tier Tribunal within 30 days of the review decision. The tribunal is independent of HMRC.
Common grounds for appeal: agent error where the taxpayer took reasonable steps to comply; HMRC system failures (e.g. MTD portal downtime); exceptional personal circumstances (illness, bereavement). Financial difficulty alone is not a reasonable excuse, but if the underlying cause was genuinely outside your control (e.g. major customer insolvency causing sudden cash flow crisis), the tribunal may accept this depending on the specific facts.
Time to Pay Arrangements
If you are unable to pay your VAT bill in full, HMRC's Payment Support Service (PSS) can arrange a Time to Pay agreement. Key points:
- Contact HMRC before the payment due date — calling after means late payment penalties may already apply
- PSS number: 0300 200 3835 (Monday to Friday, 8am–6pm)
- For amounts under £100,000 and online tax accounts, you may be able to set up TTP yourself through HMRC's online service
- A TTP arrangement stops late payment penalties accruing on covered amounts — but late payment interest continues to accrue throughout
- Defaulting on TTP payments results in reinstatement of penalties
HMRC's Business Payment Support Service processed over 950,000 TTP arrangements in 2024/25, with an average duration of 4.5 months. Businesses that proactively engage with HMRC before defaulting receive more favourable terms than those that wait for enforcement action.
HMRC Debt Management and Enforcement
Where VAT remains unpaid and no TTP is agreed, HMRC can escalate to enforcement. Enforcement options include: Direct Recovery of Debts (DRD) from bank accounts with 14 days' notice; distraint (seizure of assets) through certificated enforcement agents; county court judgment (CCJ) for amounts under £100,000; winding-up petition for companies; bankruptcy petition for individuals. HMRC can also offset outstanding VAT against any VAT repayments owed to you. Interest continues to accrue throughout enforcement proceedings.
How to Avoid VAT Penalties — Practical Strategies
1. Set Up a VAT Reserve Account
Open a separate business savings account and transfer 20% of all sales revenue received into it immediately. This ensures funds are always available when VAT is due and removes the temptation to use tax funds for cash flow. Many online business accounts (Starling, Monzo Business, Tide) allow you to create "pots" or "savings spaces" within the same account for this purpose.
2. Automate Your MTD Submissions
Use MTD-compatible accounting software (Xero, QuickBooks, Sage, FreeAgent) to automate VAT return preparation. Set calendar reminders 14 days before the filing deadline. Many platforms can automatically file returns on the deadline date if you approve them in advance. This eliminates the risk of missed submission deadlines and accumulating penalty points.
3. Switch to Monthly VAT Returns
If you regularly receive VAT repayments (common if you buy goods from abroad, have significant capital expenditure, or your output VAT exceeds input VAT), switching to monthly VAT returns improves cash flow and reduces the interest cost of waiting for quarterly repayments. HMRC processes monthly repayment claims in approximately 5 working days for compliant businesses.
4. Consider the VAT Annual Accounting Scheme
Businesses with taxable turnover below £1.35 million can apply for the Annual Accounting Scheme. You submit just one VAT return per year and make advance payments based on your previous year's liability (9 monthly or 3 quarterly payments of 10%/25%). This significantly reduces administrative burden, though it delays claiming back overpaid VAT until the year-end balancing return.
