3. Deadlines
Filing your tax return
The 2012 to 2013 tax year ended 5 April 2013. The main deadlines are:
- paper tax returns - midnight 31 October 2013
- online tax returns - midnight 31 January 2014
- final payment of any tax due - midnight 31 January 2014
If you miss the paper deadline, send your return online instead to avoid a penalty.
Exceptions
The deadline for sending the tax return can be different.
Example
Deadline: 30 December - if you send your return online, owe less than £3,000, and want HM Revenue & Customs (HMRC) to try and collect the tax through your PAYE tax code.
Example
Deadline: 31 January - if you’re a trustee of a registered pension scheme or a non-resident company (you must send a paper return because you can’t do it online).
Example
HMRC writes telling you a different deadline.
There are additional payment deadlines if you make ‘payments on account’.
You can pay HM Revenue & Customs in different ways, including direct debit and internet banking.
