<prompt> Human: We got married last November and filled our taxes as Married but filling separate. I have not changed jobs since before we got married so my original w-2 said single and I have yet to change it. My wife just got a new job and will be starting soon. What should she enter into the marital status question on the forms? We still want to file separately.  <response>: Use the IRS withholding calculator. Its likely you will have a higher tax liability if you file as MFS. If you filled out your W4 as single, you will likely owe depending on your income.
