The deadline for submitting your Self-Assessment tax return might feel a long way off, but leaving it until the last minute can create unnecessary stress. Filing early gives you more time to get your paperwork in order, understand your tax liability and plan ahead.
At E R Grove and Co, we encourage clients to get ahead of their tax obligations rather than wait until the January deadline is looming.
When is the Self-Assessment deadline?
For most taxpayers submitting a Self-Assessment tax return online for the 2025/26 tax year, the deadline is 31 January 2027. This is also generally the deadline for paying any tax owed for that tax year. If you need to submit a paper tax return, the deadline is earlier, on 31 October 2026.
Missing the online filing deadline can result in an automatic £100 penalty, even if you have no tax to pay. Further penalties may apply if your return remains outstanding, so it is worth making sure you know which deadlines apply to you.
Five benefits of filing your tax return early
1. Avoid the January rush
January is a busy time for accountants and taxpayers alike. Leaving your return until the final few weeks can make it harder to locate missing paperwork, resolve queries and get the support you need. Submitting your information early gives you more time to address any issues without the pressure of an approaching deadline.
2. Know how much tax you owe
One of the biggest advantages of filing early is knowing your tax liability well in advance of the payment deadline. Rather than guessing how much you might owe, you can work with your accountant to understand the amount due and make appropriate financial arrangements. This is particularly useful for self-employed individuals and business owners whose income can fluctuate throughout the year.
3. Reduce the risk of penalties
An early submission removes the risk of forgetting to file your return on time, provided it has been successfully submitted and accepted by HMRC. It also gives you an opportunity to check your figures, gather supporting documents and correct any errors before the deadline becomes a concern.
4. Give yourself time to find missing information
Bank statements, invoices, receipts and records of allowable expenses can take time to gather. You may also need information from employers, pension providers or other organisations. Starting early gives you time to obtain the necessary information and ensure your return is accurate and complete.
5. Make better financial decisions
Understanding your tax position earlier can help you plan your finances more effectively. You can set aside the money you need for your tax bill, manage your cash flow and discuss any relevant tax-planning opportunities with your accountant. Having a clearer picture of your finances makes it easier to plan for the months ahead.
