Missed the self-assessment filing date?
If you have missed the 31 January 2016 filing date for 2014-15 income tax returns, you should still file as soon as possible.
There is an automatic £100 penalty for missing the 31 January. But watch out – this level of penalty is for on-line submission only. If you file late on paper the penalties will be much higher.
You may have a reasonable excuse for filing late, but you must then file as soon as possible.
In exceptional cases, where you consider a return is not needed – for example because all your income was taxed under PAYE – you may ask HMRC to withdraw the return.
There is guidance on withdrawing returns and on penalties here.
Do not delay filing because you think you will be unable to pay the tax bill. If you will struggle to pay the tax, file the return now and then negotiate time to pay with HMRC. You can find out more about time to pay here.
