They will also require it of people who chronically “underpay.” If you owe over a certain threshold (I just don’t remember if it is a fixed dollar amount or a %) over several years, the IRS will require quarterly payments in addition to standard withdrawals. Essentially they make you pay to the level you “should have” if your pay cycle tax deductions are lower than their calculations.
