Why more taxpayers filed their 2025/26 tax returns early this spring
Hundreds of thousands of UK taxpayers filed their 2025/26 Self Assessment tax returns within the first week of the new tax year, well ahead of the 31 January 2027 online filing deadline. HMRC confirmed that 298,905 people submitted their 2025/26 returns between 6 and 12 April 2026, showing that early filing is now a mainstream habit rather than something only highly organised taxpayers do.
The reason is not hard to see. Filing early gives you certainty, helps you plan payments, speeds up refunds where tax has been overpaid and gives sole traders and landlords more time to prepare for Making Tax Digital for Income Tax.
For many people, especially landlords, freelancers and growing businesses, getting the return completed early is now one of the simplest ways to stay in control.
The early filing trend
HMRC has been encouraging early Self Assessment filing for several years, and taxpayers are responding. In the first week of the 2024/25 filing window, 299,419 people submitted their returns. For 2025/26, the equivalent first-week figure was 298,905, almost identical to the previous year’s record level.
That matters because early filing used to be unusual. Many taxpayers left everything until January, when pressure was high, records were harder to find and HMRC support channels were busy. Now, more people are treating the start of the tax year as the point to close the previous one.
As trusted nottingham accountancy specialists, we see this most clearly among sole traders, landlords and business owners who want to know their tax position before making decisions about cash flow, software, borrowing or investment.

Why this spring has been different
The biggest reason 2026 feels different is Making Tax Digital for Income Tax.
From 6 April 2026, sole traders and landlords with qualifying income over £50,000, based on their 2024/25 Self Assessment return, must follow MTD rules. That means keeping digital records, using compatible software, sending quarterly updates to HMRC and completing the final tax return process digitally.
The thresholds then reduce in stages. Those with qualifying income over £30,000 in 2025/26 are due to join from 6 April 2027. Those with qualifying income over £20,000 in 2026/27 are due to join from 6 April 2028.
This has changed behaviour. Filing early helps confirm whether you are in scope, gives you time to choose software and allows your accountant to help you build the right habits before the first quarterly deadline arrives.
Our guides to making tax digital quarterly update returns and MTD quarterly reporting explain the practical rhythm. For property owners, our making tax digital for landlords guide is the best starting point.
The benefits of filing early
The benefits are practical rather than complicated.
| Benefit | What it means |
|---|---|
| Certainty | You know your tax bill months before payment is due |
| Refunds | Any repayment can be processed sooner |
| Cash flow | You have more time to budget for January and July payments |
| MTD readiness | You can confirm whether you are within a future MTD threshold |
| Less stress | No last-minute January rush |
| Better records | Errors can be found and corrected calmly |
| Software setup | You have time to move from spreadsheets before deadlines bite |
Filing early does not mean paying early. Your balancing payment for 2025/26 is still due by 31 January 2027, along with any first payment on account for 2026/27 where relevant. What changes is that you know the figure earlier and can plan around it.
A clean return also helps you avoid unnecessary late-payment pressure. Our HMRC crackdown on late payments post explains why leaving tax bills unresolved is increasingly risky, while our tax refunds no longer automatic article explains why checking repayment claims carefully matters.

What you need before you file
The main barrier to early filing is usually record keeping. If your income and expenses are scattered across bank accounts, emails, paper receipts and spreadsheets, the return takes longer than it should.
For a standard Self Assessment return, you may need:
- Employment income, such as P60, P45 or P11D details
- Self-employment income and expenses
- Rental income and allowable property costs
- Bank interest, dividends and investment income
- Pension contributions and Gift Aid donations
- Student loan details
- Side income from platforms or freelance work

If your records are behind, our bookkeeping health check can identify weak spots before they slow down your return.
When professional help makes sense
Not everyone needs an accountant for Self Assessment. But professional help is sensible if you have property income, multiple income sources, self-employment, capital gains, side income, overseas income, or uncertainty about MTD.
