Taxpayers across the UK are facing a fresh wave of financial pressure as HMRC prepares to roll out a tougher penalty regime for late tax returns—one that could rake in £1 billion annually for the Treasury. Chancellor Rachel Reeves has backed the move, framing it as part of a broader crackdown on unpaid tax. But critics warn the changes could disproportionately punish small businesses, landlords, and self-employed individuals.
New Fines, Sooner and Steeper
From April 2025, VAT-registered taxpayers who miss their deadlines will be subject to significantly harsher penalties. And by 2026, the same rules will apply to self-employed income tax filers—affecting millions more. Under the revised system:
- A 3% fine will apply to unpaid tax after 15 days
- A 6% fine kicks in at 30 days
- After 31 days, the penalty climbs to 10%
For context, current penalties sit at 2% after 15 days and 4% after 30 days, making the increases substantial.
The government argues that the move will drive up compliance, but with 1.1 million people missing last year’s self-assessment deadline, the tougher approach is expected to hit many—particularly those already grappling with rising living costs.
Automation and Enforcement: Debt Collection Gets a Boost
The penalty increases aren’t the only change. HMRC is ramping up its enforcement efforts by hiring 600 new staff and spending £100 million on compliance officers. An additional £80 million will go towards third-party debt collectors, with the goal of recovering £1.3 billion over five years.
Moreover, HMRC is doubling down on automation and AI-driven systems to track late payers more efficiently. The department says the new tools will help “close the tax gap” and improve trust in the tax system, but some fear they’ll also mean more people are penalised with little warning.
Small Taxpayers Carrying the Load?
While the Treasury insists the changes are about fairness, critics argue that they’re anything but. Many small earners say they feel targeted, especially when large corporations continue to benefit from complex tax avoidance schemes that keep their liabilities minimal.
“It’s always the self-employed and small business owners who get squeezed,” said one contractor based in Birmingham. “Meanwhile, multinational companies barely feel the pressure.”
By 2028, even those earning as little as £20,000 a year could fall within the scope of these stricter rules.
Reeves Walks a Fine Line
Rachel Reeves, who has faced mounting criticism over potential future tax rises and so-called “stealth raids,” is now under further pressure to defend the changes. April is already being dubbed “Awful April” by some financial commentators, with the penalty reforms set to add to the financial burden for many households.
Despite concerns, Reeves maintains the crackdown is necessary to protect public finances and improve compliance. HMRC echoed that sentiment, stating:
“The new penalty regime is designed to make sanctions for failing to file or pay on time simple, fair and effective… to incentivise compliance and to strengthen confidence in the tax system.”
