Self-Assessment January 2026 Deadline Approaching

The deadline for submitting your Self-Assessment return online and paying any tax due for the 2024–2025 tax year is 31 January 2026. Missing this deadline could result in penalties, although these may be waived if you have a reasonable excuse.

Have you overpaid your tax?

If you’ve paid too much, HMRC will calculate any refund once your Self-Assessment return is processed. You can also check if you’re due a refund through the HMRC app after filing.

At Styles & Associates Accountancy, we support you with your tax returns so you can stay on top of deadlines and avoid the stress.
