HMRC Secure Data Exchange Service
Register for or sign into the Secure Data Exchange Service (SDES) to transfer data to and from HMRC.
HMRC uses the Secure Data Exchange Service (SDES) to send and receive data. If you’ve already registered, you can sign in to your SDES account.
You will need to register for the SDES if you:
- have been contacted by HMRC
- are a pension scheme administrator affected by the public service pensions remedy
Register for the Secure Data Exchange Service
If HMRC has contacted you to set up an account, contact the SDES support team.
If you’re a pension scheme administrator affected by the public service pensions remedy, email [email protected] with:
- ‘SDES registration’ in the subject line
- the name and Pension Scheme Tax Reference (PSTR) of the pension scheme to be registered
- your pension scheme administrator ID
- a named contact and contact email address for them
We’ll send a registration invitation code to the named contact. Once you have this, you can sign into your business tax account to access the SDES.
Sign into the Secure Data Exchange Service
To sign in, you’ll need the Government Gateway user ID and password you used to set up your business tax account.
Online services may be slow during busy times. Check if there are any problems with this service.
