This is a final reminder that the latest date that HMRC should be notified, by new Self-Assessment taxpayers, for the 2022-23 tax year, is 5 October 2023. The deadline for filing the 2022-23 Self-Assessment tax return online and paying any tax due is 31 January 2024.
There are a number of reasons why you might need to complete a Self-Assessment return for the first time. This includes if you are self-employed, have an annual income over £100,000 and / or have income from savings, investment or property.
