Get your taxes done using TurboTax

The W-4 your spouse is filling out for her employer does not go to the IRS.  It just tells the employer how much tax to withhold from her paycheck.  If she does not have enough withheld, then you could end up owing. So you do not want her income treated as if it is the only income being received.
