2019-2020 Self-Assessment Tax Return Deadline
The 2019-20 tax return deadline for submitting your paper Self-Assessment returns is 31 October 2020. Due to the impact of coronavirus, taxpayers were able to delay making their second payment on account for the 2019-20 tax year (due on 31 July 2020) until 31 January 2021.
It has also been announced that most taxpayers will be able to benefit from a separate additional 12-month extension from HMRC on the “Time to Pay” self-service facility for this payment on account and also for other payments due in January 2021 extending the deadline until January 2022.
If you are still submitting paper tax returns, we would recommend that you consider the benefits of submitting the returns electronically. This includes gaining an additional three months (until 31 January 2021) in which to submit your return. You will also receive instant confirmation that a return has been filed and not need to rely on postal service.
Late submission of a Self-Assessment return will become liable to a £100 late filing penalty. The penalty usually applies even if there is no liability or if any tax due is paid by the relevant deadline.
If you received a letter informing you to submit a paper return after 30 July 2020, then you have an extended deadline which runs for three months from the date you received the letter in order to submit a paper return.
