Personal Tax Returns
HMRC collects income tax automatically from wages, pensions and savings. However, if you have other income then you must report it in the form of a Self-Assessment Tax Return.
Deadlines for paying your tax bill
This must be filled out online or in paper form for the previous financial ending on the 5 April. The deadline for online tax returns is the 31 January and you will need to pay your bill by this date as well. The amount of Income tax that you will pay is dependent on the Income Tax band that you fall into.
