What is a self-assessment tax return

A self-assessment tax return, also known as “Personal Tax Return”, is the process in which individuals can declare their annual tax on income received or gains/profits made on their capital investments.

Some taxes, like PAYE, are collected at source, i.e. employees’ taxes are deducted before pay, and banks tax savings income when paying interest. However, income is not taxed at source in other cases, such as rental property, sole trader business, or sale of an asset that increased in value (e.g. Buy-to-let property). Instead, it must be declared, and any additional taxes paid.

Similarly, a tax return may be done to claim any overpaid taxes, e.g. the wrong tax code was entered by your employer and you were overcharged.

    • Partner in a partnership
    • Received more than £2,500 in untaxed income (e.g. you received rental income from property)
    • Investors with dividend income
    • Your savings income or investment income was more than or equal to £10,000 before taxes
    • You realised profits from selling assets such as buy to let property or shares

      Notification of chargeability

      If an individual becomes chargeable to Income tax or Capital Gain Tax for the first time, they must notify HMRC within six months of the end of the tax year in which he becomes chargeable.

      For example, an individual who received dividend income on the tax year 2020/21 has until 5 October 2021 to notify HMRC. To file a tax return, you need to be registered for self-assessment and have a UTR or Unique Tax Identifier number. A self-assessment registration form is submitted for a UTR number and can take up to 6 weeks for a UTR number to be issued by HMRC.
