Accounts office reference

Updated: May 1

What is an Accounts office reference?

13-digit unique code used by HMRC to identify your business. This code is required as a security check when you contact HMRC with queries about your employees or when making PAYE payments. Note that all Accounts office reference numbers have the same structure: three digit number of your tax office, two alpha characters and eight numeric characters.

Where can you find it?

When you register as an employer with HMRC you will receive a letter containing this reference. However, you can also find it in the majority of communications you receive from HMRC. If you cannot find your Accounts office reference number you can contact HMRC and ask for a copy which will be posted to you.

One thing to keep in mind


Be aware that that entering an incorrect Accounts office reference code when submitting PAYE information can result in possible Real Time Information (RTI) submission failures when you are processing a payrun in Zelt. This can cause delays in information reaching your HMRC account which in turn can result in a late penalty in form a comparably small interest charge. Therefore, make sure you enter your Accounts Office Reference number correctly into the Payroll app.
