Closing a self-employed business? You may think it’s as easy as shutting down your PC and never logging back in, but actually, there’s a bit more to it than that. Because, well…tax.
If you want to know all about the tax implications of closing your self-employed business, read below!
Well technically the first step is actually deciding to close your self-employed business, but anyway.👇
First things first, you need to let HMRC know what you’re doing as soon as you’ve come to the decision. You can do this online by filling out this form. Or you can call HMRC via telephone to tell them.
Once you let HMRC know, they’ll de-register you from self-employment by deactivating your UTR number so you won’t be expected to complete a tax return the following year. If you change your mind in the future, you’ll have to get HMRC to reinstate your UTR number.
If you’re registered for VAT, you should also ask HMRC to cancel this registration for you, too.
The value added tax (VAT) rates in the 2025/26 tax year 👇
Tax rate | What the rate applies to | |
Standard rate | 20% | Most goods and services |
Reduced rate | 5% | Goods and services like children’s car seats and home energy |
Zero rate | 0% | Goods and services like most food, books and children’s clothes |
*Businesses earning more than £90,000 in a tax year must register for VAT. See here for more
Now you’ve informed HMRC, they’ll know not to expect a tax return the following year, but that doesn’t mean you’ve escaped filing a tax return for the current tax year. 😅 You’ll still have to report your earnings for the year you closed your business.
Key dates in the current 2025/26 tax year 👇
Deadline | Date | Year |
Tax year starts | 6th April | 2025 |
Tax year ends | 5th April | 2026 |
Register for self assessment | 5th October | 2026 |
Pay tax bill by PAYE salary | 30th December | 2026 |
Self assessment deadline | 31st January | 2027 |
⚠️ Bear in mind, your final tax return will still need to be submitted before the deadline or you may face a late fee. ⚠️
When sending your final tax return, you should ask yourself all of the following:
If you spend any money closing down your business, you may be able to claim a tax relief for these costs to reduce your tax bill.
Here are a few examples of what can be classed as an allowable expense when closing a self-employed business:
Capital gains tax (CGT) is the tax you pay when you sell an asset for profit. So, if you’ve sold any business equipment or machinery and made a gain (this is the difference between what you paid for your asset and what you sold it for), you’ll have to pay capital gains tax.
However, you may be able to claim the business asset disposal relief on your final tax bill. This means you’ll pay a flat rate of 10% capital gains tax when selling or getting rid of any valuable items that you’ve used for your business.

If you’ve employed anyone in your business, they’ll probably (definitely) appreciate you letting them know as soon as possible that they’ll no longer be working with you soon.
(So that’s step one. 😅)
You’ll then need to close your PAYE scheme. You can do this by submitting a final payroll return with HMRC. You can fill in either of these forms:
🚨 Don’t forget to pay any outstanding wages to your employee(s), deducting any due tax and National Insurance. You have to send these tax payments to HMRC within 17 days (14 if you pay by cheque). 🚨
If you have a business partner, they’ll need to file a final partnership tax return.
If you want to stop trading as a contractor or subcontractor and you’re registered with the construction industry scheme, call the CIS helpline as soon as possible and let them know you no longer want to carry out work under the scheme.
Closing a limited company is quite different to closing a self-employed business. How this is done also depends on whether the company can pay its bills or not.
