Set up a business partnership

Register the partnership

You must register your partnership for Self Assessment with HM Revenue and Customs (HMRC) if you’re the ‘nominated partner’. This means you’re responsible for sending the partnership tax return.

The other partners need to register separately.


All partners also need to send their own tax returns as individuals.

You must register by 5 October in your business’s second tax year, or you could be charged a penalty.

Example
If you started a partnership or became a partner during the 2017 to 2018 tax year, you must register before 5 October 2018.

Other ways to register

You can also register the partnership using form SA400 if you can’t register online. You can register as a partner using form SA401.

Registering for VAT

You must also register for VAT if your VAT taxable turnover is more than £85,000. You can choose to register if it’s below this, for example to reclaim VAT on business supplies.

You can appoint an agent to deal with HMRC on your behalf.
