Freelancers in Kansas City, MO: taxes and retirement for 2026

For freelance designers, developers, writers and other 1099 professionals in Kansas City, MO. Missouri has a graduated state income tax for 2026: 2% to 4.7% (top rate starts at $9,436 for single filers). Kansas City adds a local income tax. Here are the 2026 rules, a worked example and the official sources.

What's different in Kansas City

Local income tax: Kansas City, Missouri Earnings Tax (E-Tax) and Profits Tax: 1% for residents, 1% for nonresidents (effective 1% since 1970; voters renewed it on April 7, 2026 for five years starting Jan. 1, 2027). Self-employed residents owe 1% on their business net profit wherever it is earned and file a profits return (Form RD-108/108B) by April 15, even if there is a loss. Nonresidents owe 1% on income earned inside city limits.
Kansas City, Missouri Business License Tax: Every business operating in Kansas City, including sole proprietors, needs an annual business license. The fee is graduated by gross receipts using the rate tables on Forms RD-105 and RD-103, or is a flat rate for some industries. Licenses expire Dec. 31, renewals are due by the last day of February, and fees are not prorated.
City business license: Yes: the city says all businesses operating in Kansas City must have a business license, regardless of size or type, including sole proprietors.
Also worth knowing: Rates are shown as percentages (1 = 1%). Missouri law (RSMo 92.115) requires a renewal vote every five years. The April 7, 2026 vote was called by City Council File #251029 (https://clerk.kcmo.gov/LegislationDetail.aspx?ID=7770753&GUID=B2E634F3-D548-4394-95FA-E4695184000F), which also records the 1970 increase to 1%. News outlets reported it passed with about 75% yes (https://www.kcur.org/politics-elections-and-government/2026-04-07/kansas-city-voters-renew-earnings-tax-city-revenue-elections); no official canvass was opened. The RD-108 loss-filing rule is from https://www.kcmo.gov/city-hall/departments/finance/tax-home/tax-forms. On rideshare, the city's business-license FAQ says Uber and Lyft are regulated through the State of Missouri, but drivers must still pay the 1% earnings tax. No city gig-worker pay ordinance was found.

Missouri rules for freelancers

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

Self-employment tax

On top of income tax, self-employed people pay 15.3% on 92.35% of net profit: 12.4% Social Security up to the 2026 wage base of $184,500, plus 2.9% Medicare with no cap. Half of it is deductible.

All income counts, form or no form

Clients and marketplaces send 1099-NEC or 1099-K forms only above IRS reporting thresholds, but every dollar of freelance income is taxable whether or not a form arrives.

Home office and tools

If you use part of your home regularly and only for work, the simplified home-office deduction is $5 per square foot up to 300 square feet. Software, equipment and a business share of your phone and internet are deductible too.

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

A freelancer with $85,000 of net profit in 2026
Self-employment tax	$12,010
Self-employment tax per quarter	$3,003
Solo 401(k) maximum	$40,299
SEP IRA maximum	$15,799

Federal figures only. Income tax comes on top; the quarterly tax calculator estimates both. Computed from 2026 IRS limits (Notice 2025-67, Rev. Proc. 2025-32) and the SSA wage base.
