You both filled out your W-4s as if you were the only job holder. If you have a dual income household, you need to either both check box 2c or input an appropriate amount into 4c to account for the dual incomes.

If you say married filing jointly without going to the next steps they assume you are the only income earner. Taxes are withheld so that it is like that is the only income for two people combined versus each having an income and therefore you end up under withholding.
