100 days until self-assessment deadline

HMRC is giving a reminder that customers have 100 days to file and pay their self-assessment tax return before the 31 January deadline.

If you have yet to start, you can find information and guidance on GOV.UK to help you complete your tax return.

More than 3.5 million people have already beaten the clock and submitted their returns. Starting your self-assessment early means you are more likely to complete an accurate tax return and avoid any last-minute panic – and you will know what you owe sooner and can budget, says HMRC.

Myrtle Lloyd, director general for Customer Services, says: “The countdown to the self-assessment deadline has begun but there is still time to thoroughly prepare and file an accurate tax return by 31 January. You can access online help and support to help you file.”

More than 12 million people need to file a tax return for the 2023 to 2024 tax year and pay any tax owed by the 31 January 2025 deadline.

HMRC has produced a series of YouTube videos to help you complete your return and a step-by-step guide to check what you need to do to file your first tax return.

If you’re not sure whether you need to file a tax return, go to GOV.UK to check if you need to send a self-assessment tax return.

If you’re new to self-assessment, you need to register to receive your Unique Taxpayer Reference.

If you no longer need to file a tax return, tell HMRC as soon as possible to avoid any penalties.

Beware
Criminals use emails, phone calls and texts to try to steal information and money from taxpayers. Before you share any personal or financial details, search ‘HMRC tax scams’ on GOV.UK to read a checklist to help you decide if the contact you have received is a scam. Never share your HMRC log-in information with anyone.
