I recently got married and my spouse and I are updating our W-4s to reflect this. Since we both work, we completed the Two-Earners/Multiple Jobs Worksheet and ended up needing to request additional withholding, but the number on line 8 was the same for both of us (we get paid at different intervals though, so our line 9 was slightly different).
Do we need to request this on both of our W-4s, or just one?
Since this worksheet already takes both of our incomes into account it seems like requesting additional withholding on both W-4s would be double-counting, but the form isn't very clear on this point.
Is it possible that we should simply split the amount from line 8 between the two of us?
