I’m sure this has been asked before, but I’d love some advice on dialing in my withholdings. My income can fluctuate a bit annually, plus or minus $50k or so. Nevertheless, my withholding are set to the point that I get a refund of 25-40k depending on the year. I would love to dial things in so that I’m not loaning the gov money interest free anymore. Any advice? I have a stay at home Wife and 3 kids.
