From April 2025, the UK government’s new strategy for increasing tax revenue becomes painfully clear: target small businesses and individuals with harsher penalties.
Hidden within the Chancellor’s 2025 Spring Statement is a significant and controversial update to HMRC’s penalty regime. Framed as a plan to “close the tax gap,” it actually hits those least able to bear the burden—everyday taxpayers and small business owners.
What’s Changing for Taxpayers?
The new late payment penalties come into effect from April 2025 and include:
- 📆 Miss your income tax payment by over 31 days?
- New penalty: 10%, up from 4% today.
- 📆 VAT late?
- The same escalating penalty structure now applies.
- 📆 Miss your deadline by 15 days?
- Penalty: 3%, increased from 2%.
- 📆 Miss it by 30 days?
- Penalty: 3%, also up from 2%.
And that’s before HMRC’s late payment interest rate kicks in – increasing from Base Rate + 2.5% to Base Rate + 4%. With the Bank of England’s base rate currently at 5.25%, that means a total interest rate of 9.25% on late tax.
This Isn’t About Discipline — It’s About Revenue
This policy is expected to raise:
- £5 million in year one
- £50 million by 2026
- £125 million per year by the end of the parliamentary term
Not from offshore corporations or tax-avoiding multinationals. From small business owners and self-employed individuals who may be experiencing temporary cash flow struggles.
The Double Standard: Refunds Still Delayed
- Late payments to HMRC? Expect 4%+ interest and hefty penalties.
- HMRC owes you money? You’ll be lucky to see a rate 12x lower and often longer delays.
Is that fair?
Why It Matters
These changes don’t give business owners time to adapt. No grace periods. No phased rollout. Just increased penalties, higher costs, and greater stress.
Ellen Milner of the Chartered Institute of Taxation said it best:
“Simply increasing the amount owed may do nothing but increase the barrier to settling debt, leaving everyone worse off.”
