<prompt> Human: My wife is started a new job and asked about filling out her W4. I figured Married and o is fine. Mine is currently filed as Married and 1.No kids or anything like that.Should we update our W4s?combined we make about 66k year  <response>: When you both have incomes, theres a Two Earners worksheet on page 2 of the Form W-4 where you combine your incomes, you get a combined allowances number, and then youre free to split that across both W-4s however you want. The instructions recommend the higher earner use the allowances number and the other earner use 0.The can do this for you even more precisely if you enter info about both your anticipated incomes for the year and how much withholding has happened to date. The recommendation it gives is for you both to use the Married check box on your W-4s, and itll tell you what numbers to put on your W-4 line 5.tldr: There is no problem if your W-4 settings are different. In fact, this is more often true than not.
