The 2013-14 tax return deadline for taxpayers who continue to submit paper Self Assessment returns is 31 October 2014. Tax payers who are late submitting a Self Assessment return will be liable to a £100 late filing penalty. The penalty will apply even if there is no liability or if any tax due is paid in full by 31 January 2015.

The fixed £100 penalty for failing to file a tax return on or before the filing date applies to paper returns received on or after 1 November 2014. The penalties also apply to online returns received on or after 1 February 2015.

Daily penalties of £10 per day will also take effect if the tax return is still outstanding three months after the filing date up to a maximum of £900 i.e. for three months from 1 November 2014. If the return still remains outstanding further higher penalties will be charged from six months and twelve months late.

Taxpayers that receive a letter informing them that they have to submit a paper return after 30 July 2014 have an extended deadline which runs for three months from the date they received a letter to submit the paper return. HMRC has recently published guidance for tax agents and advisers to help manage the 31 October deadline.
