All returns, and payment of tax owed, needs to be with HMRC by 31st January 2014. In previous year’s the HMRC website has failed to cope particularly well so it is wise to get your return in early.
If you wish to have any tax owed added to your tax code, (i.e. taken from your employed earnings) you will need to get your return in by 31st December 2013.
If you miss the deadline, of 31st January, there is an automatic £100 penalty even if there is no tax to pay or a refund due.
