Hi all, my wife and I need to update our W4s (filing Married Jointly) and we used the IRS' Tax Withholding Estimator to better understand how much we should each withhold. Once I entered all of our information, it gave us 2 new W4s to use. The first W4, which looks to be connected to my income, has updated the withholding dollar value in section 4C. In the second W4, which is connected to my wife's income, it did not update anything within 4C, but rather updated section 3 (Claim Dependent and Other Credits) to a negative value. I believe that is due to our son's daycare expenses.
My question is: Do we need to submit both W4s to each of our jobs? Or do we submit only 1 each? If it's only 1 each, I'm assuming I would submit the first one where it added dollars to 4C, and my wife would submit the one that updated section 3.
