I have a part time job that pays by the hour at a school. When the school is closed for breaks, I don't get paid so it is possible that I would have a pay period with little or no pay. My husband has a full time job. Right now, no Federal Taxes are being withheld because my income is too low when considered by itself. I want to have extra money withheld for my paychecks but if I enter a specific extra amount, there might be times when there is not enough pay to cover this extra amount. Is there a way to fill out section 4 so that a dynamic amount of extra withholding is done.
