Understanding PAYE Payment Reference Numbers for the 2023-24 Tax Year

When you send your tax and national insurance payments for Payroll to HMRC, it's important to include a special number. This number helps HMRC know where the payment comes from and which month and year it's for.

The number has two parts: one is your account reference number, given to you when you sign up for PAYE. This number is usually 12 digit long the format is usually 125BC254545454.

For example, if the tax year goes from April 2023 to March 2024, the year part is '24.' The month part is a number that matches the months in the tax year, starting with April as '01,' May as '02,' and so on, with March being '12.'
