What Happens If a Self-Employed Person Does Not Notify HMRC That They Stopped Working?
Failing to notify HMRC that you are no longer self-employed or that you are ending/leaving a business partnership could cause your life to get very complicated. HMRC will continue to expect you to file self-assessments and when you don’t they may slap you with penalties. It is also likely that HMRC will formulate an estimated tax bill for you that is for far more than you actually owe.
What’s more, the estimated tax bill they send you is legally enforceable, meaning you can’t just brush it off as being irrelevant because you are no longer self-employed. If HMRC send you a tax bill, estimated or not, they expect you to pay it.
You may be able to get out from under an estimated tax bill but only if you notify HMRC about your changed status and file your own tax return for the same period. Be aware, however, that there are time limits involved. If you wait too long there will be no way to escape having to pay the estimated tax.
