30 Dec 2025HMRC has urged taxpayers to file their self assessment tax returns early. Self assessment taxpayers need to complete their tax return and pay any tax owed by the 31 January 2026 deadline or risk having to pay a penalty. Those who file their return before 30 December may also have the option of paying any tax owed through their PAYE tax code. HMRC is reminding people to get their 2024/2025 self assessment tax return wrapped up early so they can make the most of the festive season. Filing early means if taxpayers owe money, they have plenty of time to decide which of the payment options available is best for them by visiting GOV.UK. Customers should include their bank account details so that if HMRC needs to repay them it can be done quickly and securely. Myrtle Lloyd, Chief Customer Officer at HMRC, said: 'For customers yet to file, there's still time to start and submit an accurate tax return. Don't leave something as important as your tax return to the last minute. Go to GOV.UK to start today.' We can help with all aspects of self assessment, including filing returns on your behalf.
