The Taxes and Duties, etc (Interest Rate) (Amendment) Regulations 2025 amend several existing regulations to increase the interest rate on unpaid taxes owed to HMRC. The changes affect various tax areas, including income tax, air passenger duty, and customs duties, raising the interest rate by 1.5% in each affected area.
The regulations came into force on April 6, 2025, and are supported by prior legislation.
Arguments For
Increased Revenue for the Government: Higher interest rates on unpaid taxes will generate more revenue for the government, potentially improving public finances and reducing the national debt.
Deterrent to Tax Evasion: Increased penalties encourage timely tax payments, discouraging tax evasion and ensuring a fairer system.
Alignment with Inflation: Raising interest rates can help align penalties with current inflation rates, making penalties more effective.
Legal Precedent: The amendments are made under existing legal powers in various Finance Acts, providing a solid legal basis for the changes.
Arguments Against
Burden on Taxpayers: Higher interest rates increase the financial burden on taxpayers who are already struggling, potentially leading to hardship for individuals and businesses.
Administrative Costs: Implementing and enforcing changes could strain the resources of HMRC leading to potential increased administrative expenditure in the process.
Impact on Businesses: Increases in interest payments could negatively impact liquidity for small businesses, potentially harming economic activity.
Potential for unintended consequences: The elevated interest rate could lead to unforeseen consequences in the business and wider economy and may encourage actions to mitigate the effects of higher taxes.
