Kansas state income tax rate 2027.
Kansas’s bracket schedule from the official source, with the 2026 figures and a labelled projected 2027 column.
Short answer: Kansas has 2 brackets for 2026 with rates from 5.2% to 5.58%. The top rate starts at $23,000 of taxable income for single filers and $46,000 for joint filers. No different 2027 schedule is enacted yet, so the 2027 column carries the 2026 schedule forward and is labelled projected.

The Kansas schedule
KDOR 2026 K-40ES estimated tax voucher (ksrevenue.gov/pdf/k-40es26.pdf) Tax Computation Schedules: MFJ 5.2% to $46,000 then $2,392 + 5.58% over; Single/HoH/MFS 5.2% to $23,000 then $1,196 + 5.58% over. Edges read from the KDOR form (statute K.S.A. 79-32,110 not read directly).
Single filers
| Taxable income | Rate, 2026 | Rate, 2027 (projected) |
|---|---|---|
| $0 to $23,000 | 5.2% | 5.2% |
| Over $23,000 | 5.58% | 5.58% |
Joint filers

2026 K-40ES standard deduction chart: Single $3,605, MFJ $8,240, MFS $4,120, HoH $6,180. Exemption amounts are in the K-40 booklet and were not read. Not modelled.
None; Kansas has no local income tax.
What changes in 2027 (projected)
KDOR Notice 26-11 (Oct 15, 2026) states FY2026 revenue was $214,339,364 below inflation-adjusted base year revenue, so under K.S.A. 79-32,110c 'there will be no rate reduction for tax year 2027'; 2027 therefore stays 5.2%/5.58% under current law, though the schedule is not otherwise printed for 2027.
The 2027 column above carries the 2026 schedule forward. That is a projection, not an enacted 2027 schedule, and it is labelled that way wherever it appears.
Worked example (2026 schedule)
A single filer with $80,000 of Kansas taxable income owes $4,377 under the 2026 schedule, an effective rate of 5.47% and a marginal rate of 5.58%. A joint filer with $150,000 of Kansas taxable income owes $8,195 under the 2026 schedule, an effective rate of 5.46% and a marginal rate of 5.58%. The 2027 projection for the same incomes is the same dollar amount ($4,377 and $8,195) because the 2026 schedule is carried forward.
Common mix-ups
- Kansas has three brackets at 3.1%, 5.25% and 5.7%. That was the pre-2024 structure; the 2026 KDOR schedules have two rates, 5.2% and 5.58%.
- Joint filers use the same $23,000 breakpoint as single filers. The 2026 MFJ schedule breaks at $46,000; Single, HoH and MFS break at $23,000.
- A 2027 rate cut is automatic because Kansas passed a trigger law. K.S.A. 79-32,110c cuts only if revenue exceeds inflation-adjusted base-year revenue; KDOR Notice 26-11 says that was not met, so no cut for 2027.
- The first bracket rate is the 5.58% top rate for all income. Only income above the breakpoint is taxed at 5.58%; the first $23,000/$46,000 is 5.2%.
Method
The tool applies each bracket rate only to the slice of income inside that bracket, adds the slices and divides by income for the effective rate; the marginal rate is the rate of the bracket that contains your income. The 2027 line uses the 2026 schedule and is shown as projected. Nothing you type is sent to our servers; the maths runs in your browser.
