Are you going back to full-time work and want to know how to de-register as self-employed, or maybe you're retiring after a successful solo career? You'll be pleased to know that letting HMRC know about your change in circumstances is a straightforward process, but an important one nonetheless.

Going back to full-time employment?

If you're going back to regular employment, you'll need to let HMRC know. You can call HMRC on 0300 200 3310 and inform them that you're no longer employed. However many have found the simplest way to do it is to de-register as self-employed online.

You'll need the following to hand:

• Your National Insurance Number,
• Unique Tax Reference (UTR).

HMRC are open Monday to Friday: 8am to 6pm. Typically phone lines are less busy before 10am Monday to Friday.

Deregistering as self employed: the basics

The steps you need to take when leaving self-employment can vary based on your future plans, but there are some common procedures that everyone must follow. You don’t necessarily need to have another job or business lined up when you decide to deregister. Some individuals may find that their income is too low to make being a sole trader worthwhile and choose to deregister in order to become eligible for benefits and other incentives. If you’re in this situation, you can find guidance on how to inform HMRC that you no longer need to complete a tax return here.

To de-register as a self-employed person, you will need to do the following:

1. Tell HMRC you’re no longer self-employed
2. Submit a final Self Assessment
3. Cancel VAT registration if required
4. Deal with any insolvency issues

These steps are explained in further detail below.

1. Tell HMRC you’re no longer self-employed 

The first step is easy – you just need to log into your online tax account via HMRC’s site and tell them you’re stopping self-employment. To do this, you’ll need your National Insurance Number and Unique Taxpayer Reference, or UTR. You’ll need to tell them the date you stopped being self-employed, which is important as it impacts potential taxes you have to pay.

2. Submit your last Self Assessment 

You must submit a Self Assessment tax return before the deadline in the relevant tax year. You’ll need to do this in the same fashion as in previous years, detailing total income minus any allowable expenses to work out total profit. If you’re selling/disposing of assets related to your business, you might have to pay Capital Gains Tax so be sure to include them on your return. 

You can, however, reduce your potential tax bill by claiming a few additional reliefs called overlap relief and terminal loss relief. Visit this HMRC page to learn more about them.

3. Cancel VAT registration

If you’re VAT registered, you need to cancel it with HMRC to avoid charges. Some business structures have trickier rules when it comes to cancelling VAT, but it’s easy for self-employed people – you can do it online via this link. 

4. Deal with insolvency issues

If you’re stepping down from self-employment, you’re probably already aware of any insolvency issues as you’ll know you have debts. It’s important to recognise that de-registering as a sole trader doesn’t affect debt. You are personally liable for them and can be taken to court or made bankrupt.

If you’ve got unresolved debts and your self-employment is ending because you’re not earning enough, you won’t be able to repay your creditors. Rather than allowing things to come to a head, it might be more beneficial to try and negotiate an Individual Voluntary Arrangement, or IVA. 

What if you're returning to employment?

If you’re deregistering as self-employed to step back into traditional employment, you still need to follow the steps above. However, because de-registering as a sole trader doesn’t generate a P45, you can’t give it to your new employer for them to use to set your PAYE code. 

Instead, you’ll have to complete a P46 form, which asks for information about second jobs, loans, benefits and other earnings. They will pass this to HMRC so you can have the correct tax code assigned. 

What to do if you're leaving the construction industry?

If you’re leaving the construction trade and you’re registered with the Construction Industry Scheme (CIS), you’ll need contact them to let them know you’re stepping down as a contractor or sub-contractor. You can call the CIS team Monday-Friday between 8am and 6pm via 0300 200 3210, or find other contact methods here. 

Converting from a sole trader to limited company

Even though owning a limited company is just another form of self-employment, HMRC still requires you to deregister in the same way we’ve covered above. You can register the limited company before you step down as a sole trader, but you should deregister as soon as you can. 

If you’ve got business assets as a sole trader and want to transfer them, you’ll need to ‘sell’ them to your new business. This can be done through a Director’s Loan – but it will affect capital allowances and capital gains taxes as part of your final sole trader Self Assessment. Speak to an accountant to help make this transition as smooth as possible. 

Looking to close your limited company?

It’s easy to confuse deregistering as self-employed with closing a limited business, since people running limited companies are still often called ‘self-employed’. Though this guide has mainly focused on closing down as a sole trader, it’s also fairly straightforward to shut down a limited business too.  Check out our handy and informative article “How to close a limited company down – Your options”.

Why not give self-employment another try?

If you’re reading this because your business hasn’t performed as well as you’d hoped and you’re considering deregistering, don’t beat yourself up. Lots of businesses fail in their first year – but you may want to try again in future.
