UK Self-Employed: Mastering Advance Payments and National Insurance for 2024/25 & 2025/26
As a self-employed individual or freelancer in the United Kingdom, navigating the complexities of tax can feel like a constant balancing act. While understanding your allowable expenses and income tax bands is crucial, two often-overlooked yet vital aspects of your tax obligations are Payments on Account and National Insurance contributions. For the 2024/25 and 2025/26 tax years, getting a firm grip on these will not only keep you on the right side of HMRC but also help you manage your cash flow more effectively.
This article delves deep into these two areas, providing practical guidance and worked examples to help you demystify Payments on Account and your National Insurance (NI) Class 4 contributions.
Understanding Payments on Account
If you're self-employed and your tax bill is over £1,000 in a tax year, HMRC will likely ask you to make Payments on Account. These are advance payments towards your next tax bill. Think of them as instalments to spread the tax burden throughout the year, rather than facing a large bill come January 31st.
How do Payments on Account work?
HMRC calculates your Payments on Account based on your previous tax year's tax liability. Typically, you'll be asked to pay two instalments:
The first payment is usually due by midnight on 31 January, covering half of the previous year's tax liability.
The second payment is due by midnight on 31 July, covering the other half.
For example, if your tax bill for the 2023/24 tax year was £4,000, your Payments on Account for the 2024/25 tax year would be £2,000 each, due on 31 January 2025 and 31 July 2025 respectively.
When might you need to adjust Payments on Account?
Life as a freelancer can be unpredictable. Your income might fluctuate significantly from one year to the next. If you anticipate your tax bill for the current tax year will be lower than the previous year, you can apply to reduce your Payments on Account. This is a crucial cash flow management tool.

Frequently Asked Questions
What's the difference between Income Tax and National Insurance for the self-employed?
Income Tax is levied on your taxable profits, with different rates applying to different income bands (20%, 40%, 45%). National Insurance Class 4 is also calculated on your taxable profits, but at different rates (6% and 2%) and contributes to your eligibility for state benefits. Both are calculated and paid via your Self Assessment tax return.
How does the Free plan work for tax calculations?
The concept of a 'Free plan' in relation to tax calculations typically refers to free online tax calculators. These tools, like the one linked in this article, allow you to input your income and expenses to get an estimated figure for your Income Tax and National Insurance liabilities without any cost or sign-up required.
How are my Payments on Account calculated?
Your Payments on Account are usually based on your previous tax year's tax liability. HMRC typically asks for two instalments, each covering half of that previous tax bill. For instance, if your last tax bill was £4,000, your Payments on Account would be £2,000 each, due on 31 January and 31 July.
