Self-assessment helps in calculating tax on your income. It is used by HMRC.

Typically, your tax is automatically deducted from your income, pensions or savings(known as PAYE) if any. However, if you have an additional source of income on which you need to pay tax then you must inform HMRC by filling a self-assessment tax return.
