Question on Registering a Partnership for Self Assessment (SA401)

Hello all,

I have formed a Limited Liability Partnership in May last year for my wife. The LLP itself has already got a UTR from HMRC shortly after the formation. Moreover we have been doing Self Assessment in the last couple of years so we also got our own UTRs.

However, recently we just realised both of us will need to register our partnership for our own self assessment using the form SA401.

We checked the HMRC website and found that we can do the registration online. We did that individually and we saw the submission was received under our self assessment's "submitted form"

It's about 1.5 months since our submissions and I just checked the status - and it said "Completed". Does that mean we have completed the registration? The HMRC page said that we will get contact within 15 days for our UTR but since we have our UTRs already, are we expected to received anything from them? Is there any where we can see our own UTRs are somehow "linked" to the LLP?

Thanks for any help in advance.
