Licensed CPA Tax Preparation and Year-Round Tax Planning for St. Louis Individuals, Families, and Small Businesses.
Filing taxes as a St. Louis resident involves more moving parts than most Americans deal with. Three separate tax returns are required for most city residents: a federal Form 1040, a Missouri Form MO-1040, and a St. Louis City earnings tax return filed with the City Collector of Revenue. Each has its own deadlines and its own deduction rules.
A 1% St. Louis city earnings tax that applies to both residents and non-residents who work within city limits, Missouri-specific credits that differ from federal options, and the federal law changes introduced by the One Big Beautiful Bill Act in 2025 and accurate, strategic tax preparation st louis mo requires more than software can reliably deliver.
World Tax and Accounting provides professional tax preparation and planning for individuals, families, and small businesses throughout St. Louis City and St. Louis County. We handle all three filing levels accurately and build year-round tax planning services St. Louis, MO, a strategy that reduces your liability before December 31.
Understanding St. Louis Tax Filing Requirements
Federal, Missouri State, and St. Louis City Three Returns, Three Sets of Rules
Federal (Form 1040): Every St. Louis resident with income above the federal filing threshold must file a federal return. The federal standard deduction for 2026 is $15,000 for single filers and $30,000 for married filing jointly under the OBBBA. New federal deductions for tips, overtime, and senior taxpayers introduced under the One Big Beautiful Bill Act apply to qualifying St. Louis residents and must be claimed correctly.
Missouri State (Form MO-1040): Missouri uses a progressive income tax with rates ranging from 0% to 4.7% in 2026 reduced from 4.8% as part of a phased rate reduction under Missouri Senate Bills 3 and 5. The first $1,000 of taxable income is exempt from state income tax. Missouri’s standard deduction for 2026 is $16,100 for single filers, $32,200 for married filing jointly (spouse does not work), and $24,150 for head of household.
Missouri does not conform to all federal tax law changes, meaning every OBBBA provision must be evaluated separately for its Missouri treatment.
St. Louis City Earnings Tax: The City of St. Louis imposes a 1% earnings tax on all income earned by city residents and on all wages earned by non-residents who physically work within city limits. It is administered separately from state and federal taxes by the City of St. Louis Collector of Revenue. A pre-tax 401(k) deferral reduces state income tax but does not reduce the city earnings tax, because the earnings tax is charged on gross wages.

Missouri-Specific Tax Planning Opportunities
St. Louis residents have access to several Missouri-specific tax reduction tools that most generic software and seasonal preparers miss:
Missouri Social Security Deduction Social Security benefits are fully exempt from Missouri income tax for single filers earning under $85,000 and married filers earning under $100,000. For St. Louis retirees just above those thresholds, income timing adjustments can preserve the exemption.
Missouri Public Pension Exemption Missouri public pension income from MOSERS, PSRS, or PEERS is fully exempt from Missouri state income tax. St. Louis public employees and educators approaching retirement should structure their income plan around this exemption from the beginning.
Missouri 529 Deduction Missouri residents can deduct contributions to a Missouri 529 education savings plan up to $8,000 per year for single filers and $16,000 per year for married filers directly from Missouri taxable income. This is a consistent annual planning opportunity for St. Louis families with children.
Missouri Property Tax Credit St. Louis homeowners and renters aged 65 and older, or those who are 100% disabled, may qualify for the Missouri Property Tax Credit, a refundable credit of up to $1,100 based on property taxes paid relative to income. This credit is frequently missed on self-prepared returns.
Missouri Charitable Tax Deductions Missouri conforms to federal charitable deduction rules but has its own threshold and carryforward provisions that differ from the federal treatment. St. Louis taxpayers with significant charitable activity benefit from coordinated planning across both returns.
