What is Self Assessment?

The self assessment tax return is a document used by HMRC to gather information that will allow calculation of tax you have to pay during the particular tax period. You must do this once a year by completing the online declaration or posting it to HMRC. In the document, you declare your taxable income and capital gains, as well as any allowances and reliefs you are entitled to.

Often in December, with the 31 January online-filing deadline looming, many people start to worry about completing their Self Assessment tax return.

Who should remember about this?

According to tax legislation, if during the period which runs from 6 April to 5 April you have been earning over £1,000 as a sole trader or a partner in a qualifying business relationship, you are required to submit a Self Assessment and pay any tax within set deadlines.

In order to complete the tax return you will also need your:

UTR

(ie the unique ten-digit reference number that enables HMRC to identify you)

NI

National Insurance number

Once all data have been entered into your Self Assessment tax return, double-check it all before submitting it to HMRC. Also take extra care when ticking boxes, as this is where mistakes can also occur. More serious errors can lead to a penalty if HMRC believes they are the result of your being careless. Do not let it happen.

If the thought of completing your first Self Assessment tax return, or making your way through another one is all too much, you can always ask an experienced professional to do it for you, or at least check and correct, if necessary, your already completed tax return. It may be cheaper than you think!
