After you’ve signed up your client

You’ll need to keep digital records of all your client’s business income and expenses.

Every 3 months you’ll use compatible software to send a summary of your client’s business income and expenses to HMRC. The software will tell you when to do this, you can also choose to send updates more often.

You’ll be able to see a year to date calculation of the tax your client owes at any time, based on the information you provide in the summary.

Send your client’s final declaration every year

At the end of your accounting period you’ll need to finalise your client’s business income and expenses. You’ll also be able to submit any personal income or reliefs they claim.

You’ll need to send your client’s final declaration and pay the tax they owe by 31st January of the following year. You can choose to pay the tax bill more regularly instead of waiting until the end of the year, but the deadlines for paying will stay the same.

The final declaration replaces the Self Assessment tax return. You’ll still need to send HMRC a Self Assessment tax return for the tax year before you signed up your client.
