Where to place MHRC activation code sent by post to access self assessment services.

cts_casemod

I have tried to register for self-assessment on the HMRC website to claim additional tax relief on my pension. They have sent me a code home, but I can't for the life of me find where to add this code. Each time I try to access my self-assessment I just go through the same menu to either verify personal questions or request this code again. Anyone knows where I can add this code to activate the service? Thanks

You don’t need to register for self-assessment for the sole reason of obtaining higher rate tax relief on pension contributions.
