What Is Self Assessment?
Self Assessment is the system used by HMRC to collect Income Tax from individuals whose tax cannot be deducted automatically through PAYE. If you are self-employed, receive rental income, earn income from investments, or have other untaxed income, you may be required to submit an annual Self Assessment tax return.
Your tax return reports your income, allowable expenses, tax reliefs, and any tax due for the relevant tax year. Filing an accurate return on time helps you avoid penalties, interest charges, and unnecessary complications with HMRC.
