Kansas, specifically
What makes Kansas different.
Kansas is one of the few two-bracket states: 5.20% up to $23,000 of taxable income and 5.58% above it for a single filer in 2026. The structure is simple, but it means nearly all of a full-time vendor's income lands in the top bracket, so the effective rate stays close to 5.58% once you are past the threshold.
- Two brackets for 2026: 5.20% up to $23,000 of taxable income, 5.58% above (single filer).
- Married filing jointly doubles the bracket threshold to $46,000.
- Because the top bracket starts low, full-time vendors should estimate near the top rate.
- No Kansas city adds a local income tax; the state return is the entire filing.
Worked example: $118,000 net income, single filer.
Same caveat as the $72,000 example: credits, dependents, retirement contributions, and QBI phaseouts move the real number. Both examples are computed from the verified 2026 brackets, not hand-written figures.
