What happens if you put exempt not knowing what it meant on your w4?

Sorry if I confused you. My daughter wants to claim exempt as she doesn’t want to go thru the hassle of filing a tax return. But, the irs documents say you can’t file exempt if you had a tax liability. So what would happen if she did file exempt ? Increasing the number of exemptions just to have less taxes taken out doesnt seen right either since she is a single female making $6k

ONCE AGAIN ... she has 2 options.

1) leave the W-4 form at SINGLE and file a tax return like everyone else even that is inconvenient for her ....

OR ...

2) adjusting the withholding any way you can ... this new W-4 form is not easy to workaround like the old W-4 was ... in the past you would simply claim more exemptions ... now you have to either add dependents (like the old exemption trick) or add deductions. Either way will produce the desired result without claiming exempt.
