St. Louis Local Income Tax: What You Need to Know

St. Louis levies a 1% local income tax on both residents and non-residents earning income in the city. This is in addition to Missouri's 4% state income tax, bringing the combined state and local rate to 5.00%.

Same structure as Kansas City — 1% earnings tax on all earned income.

The local tax applies to earned income including wages, salaries, and in most cases net self-employment income. Investment income, pensions, and Social Security are typically exempt from local income taxes.

The 1% local tax is applied on top of Missouri's 4% state income tax and federal income tax. On a $100,000 salary, St. Louis's local tax costs approximately $1,000/year — that's $83/month or $38 per biweekly paycheck.

This tax applies to both residents and non-residents earning income in St. Louis. Even if you commute from outside the city, you owe the local tax on wages earned within St. Louis.
