Confusion over form SA401

[Jamie-Valet]

HMRC Form SA401 has me slightly confused, and any advice would be greatly appreciated

So, myself and my business partner registered ourselves for self assessment, then I completed form SA400 to register ourselves as a partnership for self assessment (with myself as the nominated partner), then after receiving a letter this morning containing our UTR I added my business partner to the partnership (form SA401) and as far as I was aware this was the final step of registering - but then I read the end of the letter and it states that both partners, even the nominated partner, must complete an SA401 each? Do I actually need to fill this in if I've already registered myself for self assessment?

Thanks in advance for any advice

According to this page you need to complete it and quote the UTR you were allocated for self assessment.
