How often do I need to send in a tax return?

If you’re self-employed, you must file a Form 11 tax return once a year.

• Due by 31 October of the year after the income was earned (or slightly later if using ROS).
• Example:
  • For 2024 income, file by 31 October 2025.

Filing late may lead to penalties and surcharges, so it’s important to stay on top of your deadlines.
