HMRC is now imposing fines of up to £900 on UK households, as the three-month grace period following the January 31 tax return deadline has expired. Approximately 1 million households failed to meet the January 31 deadline, which automatically resulted in a £100 fine for each.
Penalties Escalate Over Time
With three months having passed since the deadline, additional daily penalties of £10 per day are being applied, up to a maximum of £900. Tax experts warn that these fines can quickly spiral if left unaddressed.
Myrtle Lloyd, HMRC's chief customer officer, said: "Thank you to the millions of people and agents who filed their self-assessment tax return and paid any tax owed by 31 January." She added: "Anyone who missed the deadline should file their return as soon as possible, as penalties and late payment interest may be charged."
Further Penalties for Longer Delays
The situation worsens if the deadline is missed by six months. At that point, a further penalty of 5% of the tax due, or £300, whichever is higher, will be charged. After 12 months, another 5% or £300 will be added, again whichever is greater.
HMRC, which collects tens of millions of pounds annually from penalties, will consider customers' reasons for missing the deadline. Those with a reasonable excuse may avoid being fined.
Advice for Taxpayers
Tax analysts advise anyone appealing a fine to still pay the initial penalty. Charlene Young, senior pensions and savings expert at investment platform AJ Bell, explained earlier this year: "Although it involves shelling out cash, it avoids you paying interest on the penalty itself from the date it became due if you lose your appeal." She added: "If you don't have an excuse to appeal a fine but still owe money, you might still be able to set up a payment plan to get back on track. It's essential you don't put your head in the sand."
