When do I need to register as Self-Employed?

In the UK, You are legally required to register as self-employed once the money you get paid (not your profit) goes over £1,000 during a tax year. Below this amount, you can avoid letting HMRC know about your business and paying any tax. This tax-free amount, otherwise called the trading income allowance, isn’t always appropriate to use. Therefore, make sure you do your research before you claim it.

Registering as self-employed means that you are responsible for paying your own taxes and National Insurance contributions, rather than having them deducted from your pay by an employer.

There is no specific deadline for registering as self-employed, but you should do so as soon as possible after starting your self-employment business if you expect to earn over £1,000 (turnover( within the tax year. You may be required to pay a penalty if you fail to register within three months of starting your business.

To register as self-employed, you will need to complete a registration form and provide some information about your business, such as your business name and contact details, the type of work you do, and your estimated income for the current tax year. You can register as self-employed online through the HMRC website or by phone.
