The Social Security Administration recently announced that the wage base for computing Social Security tax will increase to $160,200 for 2023 (up from $147,000 for 2022). Wages and self-employment income above this threshold aren’t subject to Social Security tax. The Federal Insurance Contributions Act imposes two taxes on employers, employees and self-employed workers. One is for Social Security tax, and the other for Medicare tax. There’s a maximum amount of compensation subject to the Social Security tax, but no maximum for Medicare tax. For 2023, the FICA tax rate for employers is 7.65% — 6.2% for Social Security and 1.45% for Medicare (the same as in 2022).
