As an accountant I’ve listened to several colleagues talk for hours about dialing in their W-2’s, some even under withholding and making quarterly payments to make up the difference. Calculating exactly what they are saving and investing that into a seperate account.
Probably spending more in fees than they’re saving. Let alone the time invested. I’m perfectly fine with the government slowly accumulating 1% of my income extra over the course of a year and sending it back later personally.
