I’m new to self employed and I’m trying to keep my child’s 30 hour free childcare place but before reconfirming I need to change my employer status on my profile but it’s saying I’m not entitled to 30 hours without a Utr number but I have tried and filled out a sa1 form and heard nothing back. Who shall I contact or will I be contacted? I keep signing into my personal tax account and see no option for self assessment but I did fill the form out online of the 6th of September.
