Self-assessment : how to correct wrong info entered

Last year I had an accountant filed the return for me. This year, I tried to do it on my own. Now I have become self-employ. When I first logged on, I was asked if my employer from last year still holds. I mis-clicked yes. Now I am stuck with this wrong info and can’t move on. What shall I do now ?

Hi yy,
Try logging out of your return, and filling it in again from the beginning, this time entering the appropriate date in the box when you first see it.
If doing this does not resolve the issue, contact us by webchat or phone here:
