After you file: refunds, balances and what comes next

A reader who has already filed wants to know what to do about an error or a balance.

Nothing here decides whether a return is due for you, what your status is, or who you may claim. Those turn on your own facts.

What the rules say

We do not work out anyone's tax, refund or balance. We explain what each rule asks for; the arithmetic belongs to you and to whatever you file with.
