PSTR
The Pension Scheme Tax Reference (PSTR) is the unique reference allocated to your scheme by HMRC.
If the scheme was registered for tax relief and exemptions on or after 6 April 2006, or you made a declaration that you were the Scheme Administrator of a deferred annuity contract.
This is the reference notified to you by HMRC in an online message on successfully registering the pension scheme or making a declaration you were the Scheme Administrator of a deferred annuity contract. If you opted out of receiving pension scheme notifications over the Internet you will have been sent a letter including the PSTR, acknowledging the scheme was registered for tax purposes or that your declaration has been received.
If the scheme was set up before 6 April 2006 and the application for approval was processed before 31 March 2006
You will have been sent an approval letter containing the Superannuation Fund (SF) reference number. The Pension Schemes Online service allows you to use this to access the scheme record for the first time. The PSTR will be given to the Scheme Administrator and/or authorised Practitioner the first time they access Pension Schemes Online on or after 6 April 2006.
If the scheme was set up before 6 April 2006 but the application for approval was processed on or after 31 March 2006
You will be sent an approval letter including the PSTR.
