After you have registered as Self Employed, you should automatically be sent a Self Assessment notice following the end of each tax year. However, as your own boss, we strongly recommend you to note the dates in your diary in case the notice does not come through.


The deadlines are:

  • 31st of January 
  • Second deadline is the 31st of July
  • Register for Self Assessment before the 5th of October


Example: the tax year runs from the 6th of April 2023 to the 5th of April 2024. You should make sure to Register for Self Assessment before the 5th of October 2024 in order to pay your tax return before the 31st of January 2025.
