Does overtime income affect our return? We owe a lot this year even though my husband and I both claim 0 to have the most taxes withheld. About 28% of his income was OT.

Married filing jointly - We have owed Federal and State (NY) the last couple of years. About 25-30% of my husband's total income is generally from over time. Is this the reason for owing? We both already claim 0 to have the most withheld and have one dependent.
