What is a Self Assessment?
What is
Self Assessment?
Self Assessment is HMRC’s calculation of the Income Tax and NI needed to pay
Employees have their Income Tax automatically deducted from their employment income through the PAYE system.
This does not happen for self-employed workers, which is why the Self Assessment is required.
You are legally required in the UK to register for and file a Self Assessment with HMRC by 31 January annually.
You need to file a Self Assessment for other types of income such as dividends, pension, income from savings and investments plus being a landlord.

When do you need to file a Self Assessment?
Everyone should complete a Self Assessment if receiving income where the tax is not deducted at source,
For example, the income received from operating as a Sole Trader or working as a Limited Company director does not have NI contributions nor Income Tax already deducted. The HMRC needs to be informed about that income on a Self Assessment form to calculate whether tax should be paid.
Crunch can advise and guide professionals through the potential minefield of Self Assessment filing.
