Kansas Tax Brackets Guide – Kansas residents and workers need a clear understanding of state income tax brackets to plan effectively and avoid surprises. Unlike the federal system with seven brackets, Kansas uses a simple two-bracket structure for individual income taxes. This guide covers the latest 2025 Kansas tax brackets (for returns filed in 2026), how to calculate your tax, deductions, exemptions, comparisons to federal rates, and other key Kansas taxes. All information comes from official sources like the Kansas Department of Revenue and the Tax Foundation as of 2026.
What Are Kansas Tax Brackets and How Do They Work?
Kansas tax brackets determine your state income tax rate based on taxable income after federal adjustments, Kansas-specific modifications, deductions, and exemptions. The state applies a progressive (graduated) system with just two marginal rates: 5.2% on lower taxable income and 5.58% on higher amounts.
Your Kansas taxable income is not the same as your gross salary or federal adjusted gross income (AGI). It starts with federal AGI, adds or subtracts Kansas modifications (via Schedule S), subtracts the standard deduction or itemized deductions, and then subtracts personal exemptions. The resulting figure determines which bracket(s) apply.
Kansas does not have local income taxes in most areas, making state brackets the primary focus for residents.
2025 Kansas Income Tax Brackets (Filed in 2026)
For tax year 2025, Kansas uses these brackets on Kansas taxable income:
Single, Head of Household, or Married Filing Separately
- 5.2% on $0 to $23,000
- 5.58% on $23,001 and above
Married Filing Jointly
- 5.2% on $0 to $46,000
- 5.58% on $46,001 and above
Exact tax calculation formulas (for taxable income over $100,000, or use the official tax tables for lower amounts):
- Single/Head of Household/Married Filing Separately: $1,196 + 5.58% of the amount over $23,000
- Married Filing Jointly: $2,392 + 5.58% of the amount over $46,000
These rates took effect after 2024 legislation that simplified the system from three brackets and slightly lowered the top rate. No further reductions (via the 2025 trigger law) apply for 2025 income yet.
Example: A single filer with $50,000 Kansas taxable income pays:
5.2% on the first $23,000 = $1,196
5.58% on the remaining $27,000 = $1,506.60
Total Kansas state tax ≈ $2,702.60
How Kansas Taxable Income Is Calculated?
Follow these steps on Form K-40:
- Start with federal AGI.
- Add/subtract Kansas modifications (e.g., subtract Social Security benefits, add certain state bond interest).
- Subtract standard deduction or itemized deductions.
- Subtract personal exemptions.
- Result = Kansas taxable income → apply the brackets above.
Nonresidents and part-year residents prorate based on Kansas-source income.
Kansas Standard Deductions and Personal Exemptions for 2025
Standard Deductions (or itemize on Schedule A if higher):
- Single: $3,605
- Married Filing Jointly: $8,240
- Head of Household: $6,180
- Married Filing Separately: $4,120
Additional amounts apply if you or your spouse are 65+ and/or blind.
Personal Exemptions (Kansas-specific, separate from federal):
- Single, Head of Household, or Married Filing Separately: $9,160
- Married Filing Jointly: $18,320
- Each dependent: $2,320
- Extra $2,320 per child born in 2025 (including stillbirth) or qualified disabled veteran.
These generous exemptions (increased in recent years) can significantly lower your taxable income.
Kansas Tax Brackets vs. Federal Income Tax Brackets
Kansas brackets are much flatter and lower than federal ones. Federal 2026 brackets (adjusted for inflation) start at 10% and go up to 37%, with much wider ranges. Most Kansans fall into the federal 12%, 22%, or 24% brackets while paying only 5.2%–5.58% to the state. Combined effective rates remain competitive nationally.
Other Taxes in Kansas: Sales Tax, Property Tax, and More
- State Sales Tax: 6.5% base rate; average combined state + local rate is 8.78% (varies by city/county).
- Property Tax: Effective rate of 1.19% on owner-occupied homes (among the lower rates nationally).
- Corporate Income Tax: 3.5% base + 3% surtax (top 6.5%), with possible future reductions.
No estate or inheritance tax in Kansas.
