What to Think About After the Self Assessment Tax Deadline
At this point in January, most conversations focus on the countdown to the Self Assessment Tax deadline on 31 January. Filing the tax return. Making the payment. Beating the deadline. It can feel as if everything stalls there.
But even before the deadline arrives, it’s worth considering what comes next. Some planning now can make the rest of the year feel much more manageable.
Filing is not the final step
Submitting your Self Assessment return is an important milestone, but it is not the conclusion of the process. Once your return is filed, there are still some practical steps to check and prepare for.
If you are filing in the next few days, make sure you:
- Keep a copy of your submission and confirmation
- Check your HMRC account shows the return as received
- Note exactly what you have paid and why
Doing this immediately prevents confusion later, especially if HMRC raises any queries.
Payments on account are easy to overlook
Many people concentrate on the tax due by 31 January and overlook that this date can also cover a payment on account for the current tax year.
If payments on account apply to you, you may be paying:
- Any remaining tax for the last tax year
- The first payment on account for the current year
Your second payment on account is generally due by 31 July. Even before the January deadline passes, it helps to be aware of what is coming later so you can plan your cash flow wisely.
January is a good moment to reflect
Once the return is nearly complete, take a step back and reflect on how the process felt this year.
Ask yourself:
- Was it easy to find your records?
- Did anything come as a surprise?
- Did you feel rushed or under pressure?
These answers often emphasise small improvements that could make next January much easier.
Preparing for the year ahead starts now
As soon as your return is filed, the new cycle begins. Organising records, maintaining updates, and establishing simple routines now can reduce a lot of stress later.
This is also a good time to consider future changes, including Making Tax Digital. Consistent, organised records will become increasingly important in the years ahead.
