<prompt> Human: Ive been claiming 0 for the past 7 months on my W4 through my employer without realizing I should have been claiming 2. I made the change. Have I been paying more in taxes on my paychecks than I should have? If so, is there any way to get this back?  <response>: If you overpaid, you will get a refund when you file your tax return.
