Most people pay tax on their earnings or pensions through PAYE (pay as you earn). Under PAYE the employer or pension provider deducts tax on behalf of HMRC, and you don't usually get a Self Assessment tax return.

However, if you are not on PAYE, and/or are due to pay additional tax because of other income not taxed through PAYE (for example from property or investments above a certain amount, or because you're self-employed) you have to account for this income through Self Assessment.

Self Assessment is so termed because it is you who are responsible for making sure the details you provide are correct. Self Assessment involves the completion of a self-assessment tax return where details of your income, expenses and capital gains must be listed.

If completed in advance of set deadlines, HMRC will calculate any tax you are due to pay; otherwise you must calculate it yourself. There are key deadlines for filing completed tax returns and paying the tax due. Missed deadlines will incur penalties and fines.
