Here’s a closer look at the rates you pay for FICA taxes, what your employer pays and how that can change if you’re self-employed.
FICA Tax Rate
All told, with the Federal Insurance Contributions Act, 12.40 percent of your paycheck is paid to the government for Social Security taxes and another 2.90 percent for Medicare, for a total FICA tax rate of 15.3 percent. If that seems steep, it’s because you aren’t paying the entirety of that. The taxes are split between you and your employer, so you’ll only see payroll tax rates of 6.20 percent withheld for Social Security and 1.45 percent for Medicare with the remainder being paid by your company.
Those taxes are different for high earners, though. There’s an additional Medicare Tax of 0.90 percent added for incomes over $200,000, bringing that total tax to 3.80 percent of which employees owe 1.90 percent.
There is also a cap on wages that can be subjected to Social Security tax. It changes from year to year; for 2018 it’s $128,400. That reflects the fact that your ultimate Social Security benefit is also capped, so you won’t pay for any more than you can expect back when you reach retirement. So, your Social Security rate can be very different if you earn much more than $128,400 a year, and that information is recorded in your Social Security information by the SSA and reflected in the maximum monthly available to you when you do start drawing benefits.
FICA Rate (Initially) Different for Self-Employed Workers
The nature of payroll taxes is fundamentally different for anyone who is self-employed. Instead of having your FICA taxes withheld from your pay, you’ll receive the full, pretax amount with each check and be responsible to self-report your earnings and pay your share of payroll taxes then.
Self-employment taxes come to 15.30 percent — 12.40 percent for Social Security and another 2.90 percent for Medicare. However, that changes for high earners, just like it does for FICA taxes, with your Social Security taxes only applying to the first $128,400 in earnings and an additional 0.90 percent Medicare tax on earnings over $200,000 a year.
Fortunately for the self-employed, you aren’t ultimately on the hook for that entire amount, though. Half of your taxes — the amount that would have been paid by your employer — are deductible from your final income tax payments.
Self-employment taxes are usually paid each quarter, every three months, as part of your estimated tax payment. You can use various online calculators available on the IRS website to calculate how much you owe. There is a penalty for failing to send in your estimated tax payments, but the majority of taxpayers avoid this if they owe less than $1,000 after subtracting all withholding and credits.
What Is FICA?
The acronym FICA stands for the Federal Insurance Contributions Act, which was the 1935 act that authorized collecting revenue through payroll taxes for Social Security. The decision to use payroll taxes was intentional so that it would ensure that the program would be able to survive because eliminating the Social Security Administration (SSA) and the payments it doles out would essentially mean robbing people of a benefit they already paid for.
“We put those payroll contributions there so as to give the contributors a legal, moral and political right to collect their pensions and their unemployment benefits,” said President Franklin Roosevelt of the decision in 1941. “With those taxes in there, no damn politician can ever scrap my Social Security program.”
Medicare, meanwhile, came into existence in 1965 as a part of President Lyndon Johnson’s Great Society. It reflected the difficulties that older Americans had in securing health insurance, given the high cost of covering the elderly.
