In the past, the due date of the prior year tax return was the same as the due date of the current year LLC annual tax. Therefore, for those who owned a LLC whic is a disregarded entity, my 'system' is to tell the clients to pay the current year LLC tax at the time when they file the prior year tax return. Same due date and it has never been a problem.
This year though, I think I have fallen into a 'trap'. While the 2020 tax return due date has been extended to 5/17, the 2021 LLC tax due date stays the same on 4/15(based on what I read). Therefore, for those clients whose LLC is a disregard entity and I plan to file their 2020 tax return in early May, I am just aware today that their 2021 LLC tax is probably past due already.
Lets say these clients pay the 2021 LLC tax later this month (April) or in early May, about how much is the late penalties on the 2021 LLC tax?
