Anybody else experienced problems with tax returns submitted in October? Submitted return online on 25 October. Tax due £695. Form accepted & no subsequent amendments. Client emails me this week to say he has not received a tax demand. Check online. Confirms return received 25 October but showing no tax payable. I then resubmit the return as a revised submission & today it is now agreeing with the £ 695. More of a widespred problem or a one off?
