Active Army. I entered my first W-2 (of 2) and it produced a tax due amount. Filing Single with 0 exemptions on my W-4 this hasn't happened before - so what changed? Adding second W-2 continued the trend of owing more. Shouldn't 0 exemptions, filing single, result in the Army taking out sufficient withholding to cover the pay they are providing (ignoring other income sources which didn't have withholding/haven't been entered yet)?
