Self-assessment Tax Return Deadlines

Submit Paper Tax Return by Oct 31st!

It’s tax return time again and HMRC has been issuing reminders for those of you who wish to submit your 2014-2015 self assessment return in paper format.

Deadline for self-assessment tax returns

The return must be filed (not just put in the post) with HMRC by midnight October 31st 2015 or you will be fined £100.  If you don’t think you can fill your return in and get to the tax man by that date then file online instead to avoid the penalty.

Online returns must be received by midnight on January 31st 2016 to avoid penalties.  If you want want HMRC to automatically collect the tax you owe then the deadline is December 30th 2015.

Whatever happens you need to pay the tax you owe by January 31st 2016 and if you are late then expect both penalties and interest charges to apply.  HMRC has provided a handy online calculator to work out what the penalties will be.
