Missed Real Time Information Reporting Pre 2018-19 Tax Year

We have some reporting that was not submitted for payments where PAYE tax was deducted and they relate to pre 2018-19 tax year. We are not able to submit via RTI as the years are time barred so please advise do we need to provide details in writing to HMRC, and where to address the letter to.

Hi Louise Stokes
Yes, please send the annual totals of liability for the entire business for all relevant years.
This should be sent to:
PT Operations North East England,
HM Revenue and Customs,
BX9 1BX
Thank you
