An Accounts Office Reference number is needed when you make PAYE payments to HMRC. It has 13 characters and normally looks like something like this:
It’s basically the way that HMRC connects your PAYE payments to your company’s PAYE account and if you don’t use it or get it wrong it can cause a delay in payments reaching your HMRC account and generally cause problems and confusion at HMRC’s end.
You may be asked for this reference number if you call HMRC to speak to them about an employee or anything else related to your PAYE account.
You’ll be able to find your Accounts Office Reference number on the letter you received from HMRC when you first registered as an employer. If you receive a payment booklet it should also be found on the front of this, or alternatively on the ‘Paying Electronically’ letter if you opted to pay electronically. It will also be printed on most letters you receive from HMRC.
When writing, quoting or typing your Accounts Office Reference number anywhere, make sure there are no spaces between the characters as this can also cause confusion and hold up any payments.
