Kansas uses a two-bracket income tax system following significant reform enacted in 2024. The legislature reduced income tax rates and collapsed the prior three-bracket structure into two simpler tiers: 5.2% on the first portion of taxable income and 5.58% on anything above that. For a single filer, the 5.2% bracket covers the first $23,000 of taxable income; married filing jointly (MFJ) filers get roughly double that threshold at $46,000 before the higher rate kicks in.
Beyond the bracket structure, Kansas has made two headline-worthy tax moves in recent years. First, the state fully eliminated income tax on Social Security benefits in 2024 — a meaningful change for the state's growing retiree population, removing the old $75,000 AGI limitation entirely. Second, Kansas phased out its grocery sales tax entirely, reaching 0% on food for home consumption by 2025, with local city and county sales taxes still applying. The same 2024 reform also raised the standard deduction slightly and replaced the flat $2,250 exemption with much larger amounts. These changes make the full Kansas tax picture more nuanced than the headline rates suggest.
Before 2024, Kansas used a three-bracket income tax structure with rates of 3.1%, 5.25%, and 5.7%. During a 2024 Special Legislative Session, lawmakers passed Senate Bill 1, which Governor Laura Kelly signed after an extended negotiation over earlier, more aggressive flat-tax proposals she had vetoed. The bill collapsed the system to two brackets, cut rates, and — less widely reported — raised the standard deduction slightly (from $3,500 to $3,605 for single filers) and substantially increased the personal exemption. The new structure creates a cleaner, more predictable system for Kansas filers, though it is not yet the flat-rate structure some legislators have sought.
The same bill also produced the full Social Security exemption (removing the old $75,000 AGI limit entirely). The grocery sales tax phase-down to zero was a separate, earlier law (House Bill 2106, 2022). The package delivered meaningful relief without the budget risk of the more radical proposals Governor Kelly had rejected.
| Rate | Single / HOH / MFS Income Range | Married Filing Jointly Range |
|---|---|---|
| 5.2% | $0 – $23,000 | $0 – $46,000 |
| 5.58% | Above $23,000 | Above $46,000 |
Kansas starts from federal adjusted gross income (AGI) and applies Kansas-specific deductions to reach Kansas taxable income. The key deductions are the Kansas standard deduction ($3,605 single / $8,240 MFJ / $6,180 head of household) and the personal exemption — which the 2024 reform (K.S.A. 79-32,121, as amended) restructured from a flat $2,250 per person into a much larger, filing-status-based amount: $9,160 for single, head of household (who also get an extra $2,320), or married-filing-separately filers, or $18,320 for married filing jointly, plus $2,320 for each dependent. Unlike many states, Kansas has not adopted federal conformity on the standard deduction — the Kansas standard deduction alone is still well below the federal $16,100 / $32,200 amounts — but the much larger 2024-reform personal exemption closes most of that gap, so combined Kansas deductions are closer to federal levels than the standard-deduction comparison alone suggests.
| Gross Income | Filing Status | KS Taxable Income | KS Tax | Effective Rate |
|---|---|---|---|---|
| $40,000 | Single | $27,235 | $1,432 | 3.58% |
| $50,000 | Single | $37,235 | $1,990 | 3.98% |
| $75,000 | Single | $62,235 | $3,385 | 4.51% |
| $100,000 | Single | $87,235 | $4,780 | 4.78% |
| $150,000 | Single | $137,235 | $7,570 | 5.05% |
| $100,000 | MFJ | $73,440 | $3,923 | 3.92% |
| $150,000 | MFJ | $123,440 | $6,713 | 4.48% |
All examples assume no dependents, no itemized deductions, and no credits beyond the standard deduction and personal exemption. Actual amounts will vary by individual circumstances — each dependent adds a further $2,320 exemption.
A critical point Kansas filers must understand: Kansas does not conform to the federal standard deduction. While federal filers receive $16,100 (single) or $32,200 (MFJ) in 2026, Kansas's own standard deduction is just $3,605 for single filers, $8,240 for married couples filing jointly, and $6,180 for head of household. This means Kansas's standard deduction alone taxes a larger share of income than states that fully conform to federal deduction amounts — though, as below, Kansas's much larger 2024-reform personal exemption significantly narrows that gap.
The Kansas standard deduction amounts are set by state law and change only through legislation — they do not automatically adjust for inflation. This has caused the deduction's real value to erode over time between reforms, making it a recurring topic in Kansas tax policy discussions.
Kansas's 2024 reform replaced the old flat $2,250-per-person personal exemption with a much larger, filing-status-based exemption: $9,160 for single, head of household, or married-filing-separately filers, or $18,320 for married couples filing jointly — plus an additional $2,320 for each dependent. This is separate from and in addition to the standard deduction. A married couple with two dependents can claim $18,320 (MFJ exemption) plus $4,640 (2 × $2,320 dependent exemptions) plus the $8,240 MFJ standard deduction — $31,200 in total deductions before any tax is applied. A qualified disabled veteran may also claim a separate additional $2,320 exemption (Kansas K-40 instructions, tax year 2025 and later).
One of the most significant features of the 2024 Kansas tax reform is the complete elimination of state income tax on Social Security benefits. Before this change, Kansas taxed Social Security income that exceeded certain adjusted gross income thresholds, mirroring the federal approach to Social Security taxation. The 2024 law exempts all Social Security benefits from Kansas income tax unconditionally — no income test, no phase-out, no partial credit. This puts Kansas alongside a growing list of states (including Missouri, which also recently eliminated Social Security taxes) that have chosen to spare retirees this particular tax burden.
Before 2024, Social Security benefits were already subtractable when federal AGI was $75,000 or less, so the change mainly helps retirees whose federal AGI exceeded $75,000.
Kansas enacted a multi-year phase-down of its grocery sales tax in 2022 (House Bill 2106); it had been taxing groceries at the full state rate. The plan: reduce from 6.5% to 4% in 2023, then 2% in 2024, and reach 0% by 2025. That final step occurred on schedule, so Kansas now charges 0% state sales tax on food for home consumption (local taxes may still apply).
The practical impact is substantial for Kansas families. A household spending $700 per month on groceries ($8,400/year) would have paid $546 per year in state grocery tax at the old 6.5% rate. At 0%, they pay nothing — a direct $546 annual saving per household that partially offsets Kansas's still-high general sales tax rate of 6.5%.
Unlike the income tax and grocery pictures, Kansas property taxes are a less favorable story. The state's effective property tax rate averages approximately 1.21% of market value — above the national average of ~0.90% (Tax Foundation, 2024 Census data) and considerably higher than most neighboring states including Missouri (~0.89%) and Oklahoma (~0.79%). On a $250,000 home, Kansas property taxes average approximately $3,025 per year. County and city variations are significant; Johnson County (Kansas City metro area) tends to run higher than more rural central Kansas counties.
Kansas does offer a Homestead Property Tax Refund for low- and moderate-income homeowners and renters, as well as a Safe Senior Property Tax Refund for residents age 65 or older meeting income requirements. These programs partially offset the higher property tax burden for qualifying households.
