My wife and I are married, both work, have a child, filing jointly. Last year, checked around online and all seemed to say taking 3 allowances makes sense for married couple with one child. So I took 1 allowance, she took 2. When we just entered our W-2s, it says we'll owe $8,000. Should we not have taken 3 allowances on W-4 all of last year?
