Value Added Tax returns for the quarter ended 30 September 2015 are due to be submitted by 7 November, and any payment which is due should be made electronically by the same date.

 
If you had any income from self-employment or any capital gains for the year ended 5 April 2015, and you intend to submit a paper tax return, then the deadline is 31 October 2015. The same tax return can be submitted electronically, in which case the deadline is 31 January 2016. This is also the deadline for any accountant in public practice who will prepare any accounts and submit an electronic tax return for you for a fee. It is advisable to see an accountant if you have left things this long.

 
Small private companies with a year end of 31 January 2015 and into their second or later year of existence should submit their accounts to Companies House by 31 October 2015 in order to avoid a Late Filing Penalty.

 
Sometimes when you are an employer, you might have happened to have made no wage or salary payments at all for a PAYE month such as the month from September 6 to October 5 2015, in which case you must submit electronically an Employer Payment Summary as a NIL return by October 19. This is too easy to overlook.

 
Employers must make Second Quarter payments of PAYE and NICs by 19 October 2015 if settled by cheque. If you pay electronically, then you have until 22 October to make the payment. Tax retained under the Construction Industry Scheme must also be paid by the same date.
