HMRC have stopped sending Company Tax Return Payslips and are prompting customers to check CT Online where they can see their return details. HMRC are still serving a ‘Notice to deliver a Company Tax Return’ after the financial year end which contains your 17 digit payment reference. It’s important to keep this letter each year as the reference changes.

Corporation Tax Deadlines
Make sure you pay HM Revenue and Customs (HMRC) by the deadline. Your Corporation Tax payment is normally due by 9 months and one day after the end of your accounting period. So, if your Company Tax Return covers your accounting period 1 January 2022 to 31 December 2022, then Corporation Tax must be paid no later than 1 October 2023.

Online debit or credit card (3 working days)
If you have a debit or credit card from a UK card issuer, you can pay your Corporation tax online. You will also need your 17 Digit pay reference to make payment. Your reference number is specific to the accounting period you are paying so please quote it exactly. The first 10 digits of your pay reference is made up of the unique tax reference. If you don’t know your specific reference for the accounting period you want to pay, you should contact HMRC on 03000 583 945.
