if I file a joint return I put in my info 69k and it shows 1k refund(6kfed tax paid) I then put in her income 18k (1.5k fed tax paid) it shows 392 refund. if I file separate returns it shows I owe 2.3k on my return and I put her info in on a separate return and she gets $900 back. my w4 has 1 deduction hers is 0. should I change something and file separate returns so she gets more money back or is it better to file jointly
