Deadlines for Self Employed

By: In2Accounting

The key dates that you must know about if you are a self-employed taxpayer are spread throughout the calendar year. If you put them in your diary now, you’re less likely to  miss them.

 

5 October 2017 – If you need to advise HMRC that you need to register for Self-Assessment for the next tax year, this is the deadline. If you became self-employed in the 2016 tax year, this is the deadline to register, through the submission of the CWF1 form for self-employment.

31 October 2017 – If you want to file your individual tax return on paper instead of online, it must be submitted by 31 October.


31 January 2017 – This is the final deadline for online self-assessment tax returns, unless the notice to file the return was received from HMRC after 31 October 2016, in which case you have three months to file the return. The balance of any tax for the 2015-2016 tax year must be paid.

If you have to make payments on account for your tax bill – including Class 4 National Insurance if you are self employed – the first of those must be received by midnight on 31 January. If you think a previous tax return is wrong, you can amend the tax return for up to 12 months after 31 January.


1 February 2018 – This is when you will be automatically fined £100 if HMRC issued you with a 2016/17 tax return before 1 November 2016. Interest will start to accumulate on any unpaid tax.


5 April 2018 – This is the end of the 2017-2018 tax year.


6 April 2018 – This is the start of the 2018-2019 tax year.


31 May 2018 – Copies of P60 documents should be issued to any employees, where applicable.


6 July 2018 – Copies of P11D documents to be issued to employees, where applicable.


31 July 2018 – This is the deadline for the second payment on account to be made towards next year’s tax bill.
