We have recently had a query asking whether or not it is still possible to pay bills to HMRC by cheque sent by post.
This information from the Government website, https://www.gov.uk/pay-paye-tax/by-post dated 7th December 2016 confirms that payments can still be made by cheque made payable to HM Revenue and Customs only, followed by your 13-character Accounts Office reference number. You can find this on the letter HMRC sent you when you first registered as an employer. You must also include the payslip for the correct period, and send to this address

If you pay by cheque through the post the deadline is the 19th of the month.
