Self-assessment tax refers to a system where individuals, trustees, and businesses assess their own tax liability and report it to the tax authority, rather than having it automatically deducted by an employer or other third party.

Here’s how it generally works:

  1. Assessment: Taxpayers are responsible for assessing their own tax liability. This involves calculating the total amount of income they’ve received during a tax year, deducting any allowable expenses or reliefs, and determining the amount of tax owed.
  2. Tax Returns: Taxpayers are required to complete a tax return form, detailing their income, expenses, and reliefs for the relevant tax year. This form is usually submitted to the tax authority by a specific deadline.
  3. Payment: Along with the tax return, taxpayers typically need to pay any tax owed to the tax authority. Payment is usually made electronically or by mail, following the instructions provided by the tax authority.
  4. Deadlines: There are strict deadlines for filing tax returns and making tax payments. Missing these deadlines may result in penalties and interest charges.
  5. Records: Taxpayers are required to keep accurate records of their income, expenses, and any other relevant financial transactions. These records may be requested by the tax authority for verification purposes.

The self-assessment tax system is administered by Her Majesty’s Revenue and Customs (HMRC). Taxpayers are required to register for self-assessment if they meet certain criteria, such as being self-employed, earning rental income, or having income from investments. They must then submit their tax returns and any associated payments by the relevant deadlines, usually by January 31st following the end of the tax year for online submissions, and by October 31st for paper submissions.

Overall, self-assessment tax puts the onus on taxpayers to accurately report their income and pay the correct amount of tax, ensuring compliance with tax laws and regulations.
