Tax relief on SIPP for higher-rate tax payer – can I just call or must I do a self-assessment?

Hi, I’m a higher-rate tax payer, so can claim relief on payments into my SIPP on top of the standard 20% tax relief. Can I organise this through a phone call or do I have to register for self-assessment (I have no other reason to do a self-assessment so would like to avoid it). If it can be sorted with a phone call, what is the best number? Thanks for any help.

Hi yingyang99,
You do not need to file a Self Assessment return to claim tax relief on your Personal Pension Payments.
You can do so by phone, webchat or post here:

Thank you.
