I am filing for my retired mother....how do I get a service code so she does not have to pay the exorbitant amount since she is on social security

[DoninGA]

If the Social Security benefits are the Only income to be reported on the tax return, then there is no reason or need to file a tax return.

If her ONLY income is Social Security she does not even have to file a tax return unless she has a 1095A for marketplace insurance or had tax withheld from the SS and needs a refund.

If she had OTHER income besides the SS she might need to file.

Who has to file?
