HMRC is urging UK taxpayers to avoid a last minute rush and complete their 2017-2018 self-assessment tax return early.
Taxpayers can complete their self-assessment for the previous tax year from as early as 6 April, but many choose to wait until after Christmas to fill it in.
Last year, more than 11 million customers completed a 2016-2017 tax return, with 10.7 million taxpayers completing the form on time. January 2018 saw 758,707 people leaving the task until 31 January, deadline day.
With 100 days to go before the next deadline on 31 January 2019, HMRC is telling taxpayers that they can complete their tax return in advance, find out how much tax they need to pay and pay the money owed by the deadline.
"Self-employed workers and small businesses make up a significant proportion of our self-assessment tax returns and the Government is committed to supporting them and reducing the administrative burden they may face," said Mel Stride, financial secretary to the Treasury. "The Personal Tax Account, for example, allows you to file your return and manage your tax affairs online, quickly and simply, whenever you want."
Angela MacDonald, HMRC's director general for customer services, said: "The deadline for completing self-assessment tax returns may be 100 days away, yet many of us wait until January to start the process ? We want to help people get their tax returns right - starting the process early and giving yourself time to gather all the information you need will help avoid the last minute, stressful rush to complete it on time."
Tax is automatically deducted from the majority of UK taxpayers' wages, pensions or savings. For people or businesses where tax is not automatically deducted, or when they may have earned additional untaxed income, they are required to complete a self-assessment tax return each year.
Last year, a record 93% of customers did their return online. HMRC provides films and webinars to show each stage of the process. Help is also available on the Government website self-assessment pages or via the helpline on 0300 200 3310.
The deadline for paper tax returns is 31 October 2018 and the deadline for online tax returns and paying any tax owed is 31 January 2019. If customers miss the deadline, they can face a minimum £100 penalty for late submissions.
