Kansas City and St. Louis Tax Freelancers on a Separate Return

Missouri's state income tax tops out just under 5% and steps up in small increments, which makes it unremarkable. What makes Missouri worth reading carefully is that two of its cities run their own earnings tax, and the rules for self-employed people are different from the rules for employees.

One percent of net profit, on its own form

Kansas City and St. Louis each levy a 1% earnings tax. For an employee it comes out of the paycheck and nobody thinks about it. If you are self-employed, nothing is withheld and you file a separate return: Form RD-108 with RD-108B in Kansas City, or the E-2 return in St. Louis. It is due alongside your April federal deadline.

Unlike Washington's B&O or New Mexico's gross receipts tax, this one is charged on net profit, so your business deductions do reduce it. That makes it much less punishing than its gross-receipts cousins. It is still a full percent that most Missouri tax summaries skip.

You file even in a year you lost money

Kansas City requires the RD-108 and RD-108B whether or not you turned a profit. A loss year does not excuse the filing, it just means the return shows a loss. Freelancers who assume no profit means no paperwork tend to find out through a notice rather than through the instructions.

It follows the work, not just your address

If you live in Kansas City or St. Louis, the tax applies to your self-employment income generally. If you live outside but perform work inside the city limits, the city-sourced portion is still reachable. Plenty of freelancers in the surrounding suburbs assume the tax is a city-resident problem and never look further.

You are also expected to make quarterly estimated payments toward it rather than settling the whole thing in April. Our calculator covers Missouri state tax and flags the local layer, but it cannot tell whether your work is inside either city, so check your situation with Kansas City or the St. Louis Collector of Revenue.
