If you send a paper tax return it must reach HMRC by midnight on 31 October.
So for the 2016-17 tax year (ending on 5 April 2017), the deadline for paper returns is midnight on 31 October 2017.
There are very few exceptions. As an example, the deadline may be later if HMRC send you the letter, telling you to complete a tax return, after 31 July. In this case the letter will tell you the deadline - it is usually three months from the date of the letter. Or if you're sending a Self Assessment return for a registered pension scheme or non-resident company, you can only send paper returns so the deadline isn't until 31 January.

VAT Returns are not annual returns, so there is no fixed date in the year for them to be filed, they are filed for a 'VAT period' unless the trader is registered under the 'Annual Accounting Scheme'
VAT periods are usually of 3 months duration (referred to as a quarter) or 1 month, depending on the VAT scheme the trader is registered under.
VAT Return for the period must be filed and any VAT due must be paid. An extension of a further 7 days beyond this date is available if the return is filed online.
Depending on whether registered under a monthly or quarterly VAT scheme, estimated VAT is payable at the end of each month (9 payments) or each quarter (3 payments)
VAT Return and balancing payment for the accounting period must be filed and any VAT due must be paid.
