If you are married, you cannot file single.
There are only three ways a
married person can file
- married filing jointly (MFJ)
- married filing
separately (MFS)
- head-of-household (HOH).
The IRS requires married
couples, whether together or separated, that are filing as married
filing separately to provide their spouse or ex-spouse's social security
number because they want to compare the two returns.
The IRS requires
all tax software companies to request the other spouse's social
security number.
If for some reason a person does not want to give or
does not have the other spouse's social security number, they would not
be able to efile their tax return, but instead would have to paper file
their return by printing, signing, dating and mailing.
