Missouri rules for construction & trades
- State income tax (2026)
- Missouri has a graduated state income tax for 2026: 2% to 4.7% (top rate starts at $9,436 for single filers). 2026 brackets: the first $1,348 of taxable income is taxed at 0%, then rates run from 2.0% up to 4.7% on taxable income over $9,436. The same brackets apply to every filing status. A legislative constitutional amendment to phase out the income tax (HJR 173/174, Amendment 5) appeared on the August 4, 2026 primary ballot (sos.mo.gov) and was defeated by voters, so 2026 rates are unchanged.
- State estimated tax
- You must file a declaration and pay estimated tax if your Missouri estimated tax (after withholding and credits) is expected to be $100 or more (Section 143.521.1, RSMo). Same dates as federal (April 15, June 15, September 15, January 15). Farmers may pay by January 15, or file and pay in full by March 1. Form MO-1040ES.
- Unemployment right-to-control test (RSMo 288.034.5)
- Missouri unemployment law uses the common-law right-to-control test. If the business controls the manner and means of the work, the worker is an employee; if it controls only the results, the worker is an independent contractor. Some licensed real estate agents and direct sellers paid on output under a written contract are excluded.
- Rideshare (TNC) driver contractor status (RSMo 387.414)
- Rideshare drivers are independent contractors, not employees, if the company does not set required logged-in hours, does not bar them from other rideshare apps, does not restrict other work, and both sides agree in writing that the driver is a contractor. In effect since August 28, 2017.
- State retirement program
- Show-Me MyRetirement Savings Plan is live. It is built around W-2 employers and does not cover 1099 contractors through the employer mandate.
Federal rules for 2026
W-2 or 1099 changes everything
On a W-2 your employer withholds tax and may offer a retirement plan. As a 1099 subcontractor you pay self-employment tax and quarterly estimates, but you can deduct tools, materials and job-site driving.
Tools and equipment
Tools, equipment, safety gear and work vehicles used for business are deductible; larger purchases can often be written off in the year you buy them.
Overtime deduction for W-2 workers
Non-exempt W-2 workers can deduct the overtime premium they are paid, up to $12,500 a year ($25,000 joint) from 2025 through 2028, subject to an income phase-out.
Quarterly estimated taxes
No one withholds tax from self-employment income, so you generally pay estimates four times a year if you expect to owe $1,000 or more. For 2026 income the federal dates are April 15, June 15 and September 15, 2026, and January 15, 2027. Paying 100% of last year's tax (110% if your AGI was over $150,000) in four equal installments avoids the underpayment penalty.
A worked example
