St. Louis Earnings Tax: Refunds and Remote Work

City vs. County

Why does the city-county distinction matter so much?

St. Louis is one of the few US cities that is an independent city, separate from any county. St. Louis City and St. Louis County are distinct governmental entities with separate tax systems. The 1% earnings tax exists only within St. Louis City. The county has no equivalent. This creates three common scenarios:

• City resident, city worker: You owe 1% on all earned income. No question.
• County resident, city worker: You owe 1% on wages earned within city limits. If you start working from home in the county, those remote days should not be subject to the city tax.
• City resident, county worker: You still owe 1% on all income because the resident obligation covers all earned income regardless of where you work.

The dividing line between city and county is geographic, not always obvious, and some neighborhoods near the boundary create confusion. Your address determines whether you are a city or county resident for earnings tax purposes.

How does the remote-worker refund process work?

If you are a nonresident (typically a county resident or Illinois commuter) whose employer withheld the 1% earnings tax on days you worked remotely from outside city limits, you can file for a refund with the St. Louis Collector of Revenue.

The refund process requires:

1. A record of days worked within the city vs. outside the city (work log, employer letter, badge swipe data).
2. A completed refund request form from the Collector of Revenue.
3. Supporting documentation such as your employer's remote-work policy or signed statement confirming your work arrangement.

The practical challenge is that many employers withhold based on their office location and do not track individual employee work locations day by day. You may need to create your own log and have your employer attest to its accuracy. The burden of proof falls on the employee requesting the refund.

Has the earnings tax faced legal challenges?

The St. Louis earnings tax has been a political and legal battleground for years. Key issues include:

• Remote-work litigation: Lawsuits have challenged the city's right to tax nonresidents who stopped commuting and worked from home. The core legal question is whether the tax can be imposed based on where the employer is located vs. where the work is physically performed.
• Repeal efforts: Missouri state legislators have periodically proposed bills that would require the tax to be renewed by voters (similar to Kansas City's model) or phase it out entirely. None have succeeded in eliminating the tax, but the political pressure has kept the issue visible.
• Economic impact debate: Critics argue the tax drives employers and residents out of the city to nearby county or Illinois locations. Supporters counter that the tax funds essential city services and that eliminating it would create a fiscal crisis.

As of this writing, the 1% tax remains in full effect. Check current Missouri legislative developments for any changes to the tax's structure or application.

How does the earnings tax interact with Missouri and Illinois state taxes?

The earnings tax stacks on top of Missouri's graduated state income tax. Missouri does not give a credit for the city earnings tax against state tax — they are independent. For Illinois residents commuting to St. Louis, the situation involves state reciprocity: Missouri and Illinois do not have a reciprocal agreement, so Illinois commuters may owe both Illinois state tax and Missouri state tax (with a credit on the Illinois return), plus the 1% city earnings tax. This makes the cross-border tax burden for East St. Louis area commuters particularly high.
