A tax question from a new business owner

pawntoc5

Hello all,

I formed a company last year to run my own business under and I had a few quick questions that I couldn't get clarity on via online research so hoping someone here could help me... for context, I've never had to file my own taxes as I was previously an employee of another company and taxes were always done automatically (as I had no other income to declare).

I've filed and paid my corporate tax already but I know that I, as an individual, also need to register for self-assessment and file a personal tax return. I'd completed the Self Assessment Form here and was expecting an activation code from HMRC to continue. However, when the code arrived and I logged in with it using my personal UTR (not my company UTR), the login page only showed details for corporate tax returns and had nothing on personal taxes at all.

Am I going about this (filing personal tax returns/self-assessment) completely wrong?

I'd tried calling HMRC as well but they're always busy (to the point where they don't tell you to hold, and just stay "we can't take your call").

Any help or insight would be much appreciated!
