A record number of taxpayers have already filed their 2025/26 self assessment tax returns, as more people choose to get ahead of the January deadline.
Figures from HMRC show that 737,891 taxpayers submitted their returns in April, setting a new record for early filing.
The busiest day was 6 April—the very first day of the new tax year—which fell on Easter Monday. On that day alone, 86,270 people filed their returns, making it the most popular filing date so far.
By the end of the first week of the tax year, 298,905 taxpayers had already completed and submitted their 2025/26 returns.
HMRC says filing early can offer practical benefits. Those who are due a refund may receive it sooner, while others can gain a clearer picture of what they owe well ahead of the payment deadline.
Early filing can also reduce the pressure that often builds in January, when millions of taxpayers rush to meet the final deadline.
Anyone unsure whether they need to submit a return can use HMRC’s online checker tool on GOV.UK. Those new to self assessment must register first to receive a Unique Taxpayer Reference before they can file.
Myrtle Lloyd, HMRC’s Chief Customer Officer, said early filing is becoming the norm for thousands of people who want to stay on top of their finances and avoid last-minute stress.
The figures suggest a growing shift in taxpayer behaviour: rather than waiting until the deadline approaches, more people are choosing to deal with their tax affairs early—and move on with the rest of the year.
