Hello, I graduated two years ago and have been working since, I recently changed jobs and have received a letter from SF. It outlines that HM Revenue have informed them of the employment change, and that I need to update SF about my new role by filling out the provided form (otherwise I'll face a fine). How long do I have to complete this form and send it off, without incurring any costs? I thought any employment changes were automatically changed on SF end, didn't realise that we had to tell them.
Thanks,
KL
