Self Assessment 2024-2025: Don’t Leave It to the Last Minute
It’s that time of year again – Self Assessment for the 2024-2025 tax year is open (and we’ve already filed a number of tax returns for clients!). Yes… the official deadline is 31 January 2026, but why leave it until the last minute? Filing early can save you stress, give you peace of mind, and even get your refund sooner.
At BAS Associates, we see it every year – leaving it until the last week can be stressful. Avoid the rush and get ahead now.
Who needs to file a tax return?
You need to complete a Self Assessment tax return if:
- You’ve told HMRC you’re leaving Self Assessment but still have some income to report from 2024–2025.
- HMRC has already asked you to file a return. If you think you don’t need to, you must notify them.
Ignoring these requirements can lead to repeated reminders and, eventually, penalties.
Thinking you might not need to file? Dive deeper into who actually needs to complete a Self Assessment in this post for a full breakdown.
Not sure if you should be registering for Self Assessment or paying tax through PAYE? We explain it simply in this guide to help you avoid mistakes.
The benefits of filing early
Filing early isn’t just about avoiding stress – there are real benefits:
- Budget with confidence – knowing your tax bill ahead of time helps you plan.
- Proof of income when you need it – perfect for mortgage, loan, or benefit applications.
- You could be due a refund – why wait for money that could be in your account today?
Filing early gives you control and peace of mind. No last-minute panic, no rushed mistakes.
