Kansas has the shortest progressive schedule in this batch, just two brackets, and the second one starts early. A single filer passes from 5.2 percent to 5.58 percent once taxable income passes $23,000, so on an $80,000 salary, most of the pay is taxed at the top rate, and the lower rate applies to only the first slice. The schedule looks progressive, but at ordinary salaries it behaves almost like a flat tax with a small discount at the bottom.

Worked example: $80,000 single, no pre-tax deductions
Take a single filer with an $80,000 salary and no pre-tax deductions. State taxable income is $80,000 minus the $3,605 single standard deduction, which is $76,395. The tax is calculated slice by slice:
| Slice | Tax |
|---|---|
| First $23,000 at 5.2% | $1,196 |
| Remaining $53,395 at 5.58% | $2,979.44 |
| Total state tax | $4,175.44 |
The marginal rate is 5.58 percent, because the last dollar sits in the top bracket. The effective rate on taxable income is $4,175.44 divided by $76,395, about 5.47 percent, and on gross pay it is about 5.22 percent. Paid biweekly, the state line is $4,175.44 divided by 26, about $160.59 per paycheck.
The gap between the marginal and effective rates is small, only $84.56 on the whole bill, because the lower slice saves just 0.38 percentage points on $23,000. That is the whole benefit of the two-bracket design at this salary, and it shrinks as a share of the bill as pay rises.
Joint filers, and the exemption beside the figure
Joint thresholds are double the single ones at the first step: $46,000 at 5.2 percent, then 5.58 percent above, with a $8,240 joint standard deduction. At $80,000, joint taxable income is $71,760, the first slice contributes $2,392, the remaining $25,760 contributes $1,437.41, and the total is $3,829.41, about $147.28 biweekly. Kansas also gives a personal exemption of $9,160 single and $18,320 joint, which is not in the standard deduction fields, so a filed return can differ from the calculator figure for that reason as well.

FAQs
Is Kansas really only two brackets?
Yes, for 2026: 5.2 percent to $23,000 single, then 5.58 percent above. Joint thresholds are $46,000 at the first step.
Why is Kansas's bill higher than Iowa's at $80,000?
Because Kansas's rates are 5.2 and 5.58 percent against Iowa's flat 3.8 percent, and Kansas's single deduction is only $3,605 against Iowa's $16,100. Both the rate and the deduction push Kansas higher.
Does a raise change the Kansas rate?
Not at $80,000, because the filer is already in the top bracket. Every extra dollar of taxable income adds 5.58 cents of Kansas tax, with no further threshold to cross.
