I've tried finding an answer to this issue both here and elsewhere on the web and haven't been able to so far. My husband got a new job last month with a significant salary increase, and I've been trying to readjust our allowances. My goal is to get as close as I can to our estimated taxes without underpaying or grossly overpaying.
I have tried to use the IRS's helpful calculator, but it works from the current date and thinks I'm trying to plan from now to the end of 2014 rather than plan ahead for next year. As there is not yet a withholding calculator available for 2015, I am using the W-4 worksheet for 2015 which was released a few weeks ago.
According to the worksheet results for a dual-income household like mine (he makes 80,000, I make 25,000), we should have 0 allowances and have an additional $76.92 withheld. What I'm confused about is, which spouse should file this W-4? Should we both fill ours out the same way? Should I even use these numbers or would it be better to wait for the 2015 calculator?
Neither the IRS or any of the tutorials I've found specify who should file this and if not both, what the other spouse should put down. We do not have kids or file Schedule A. I was hoping this would be a bit less complicated and I feel as though I'm close to an answer, but any clarification would be very helpful.
