Go through one of the W4 calculators first, which will tell you what to put on his form and what to put on your form. Then submit each updated form through each of your places of employment.

W-4 Calculator options:

Yeah I'm not a fan of it.

I filled it out perfectly a few years ago so that my wife and I got like $100 back or something like that (we wanted to have the least amount given as a refund) then the next year I was afraid it wouldn't take into account our bonuses and I redid it. Now we get a much larger refund than I want, but I really don't want to fill it out again.

Maybe the last time he filled it out was before they changed the way that you're supposed to fill it out?
