Self Assessment tax returns are a method used by tax authorities

Self Assessment tax returns are a system used by tax authorities, such as HM Revenue and Customs (HMRC) in the UK, to collect income tax. Individuals and businesses must file these returns if they have income or gains that aren't taxed at source, such as from self-employment, rental properties, or investments. The process involves reporting income, claiming allowable expenses, and calculating the tax due. Self Assessment requires accurate record-keeping and timely submission to avoid penalties. It offers a way for taxpayers to ensure they are paying the correct amount of tax and provides an opportunity to claim any tax reliefs or deductions they are entitled to.
