When most workers look at their pay stubs, they can see that the Social Security payroll tax rate is 12.4 percent – with the employee and employer each paying 6.2 percent. But many workers do not know that any annual wages above $106,800 are not taxed by Social Security. In other words, a worker who makes twice the Social Security wage cap – $213,600 per year – pays Social Security tax on only half of his or her earnings, and one who makes just over a million dollars per year pays the tax on only about a tenth.
Raising the Social Security cap – which would make some or all earnings above $106,800 subject to the Social Security tax – has gotten some attention as a way to help alleviate Social Security’s long-term budget shortfall.
