Kansas has a fairly standard tax code—with few features that make it either distinctly competitive or uncompetitive—and this is reflected in the state’s ranking near the middle of the pack. Kansas’ individual and corporate income taxes both have graduated-rate structures, with brackets, a standard deduction, and a personal exemption that are not indexed for inflation. Kansas’ top marginal individual and corporate income tax rates, as well as its combined state and average local sales tax rate, are all at or above the national median.
While Kansas exposes an outsized share of business income to its corporate income tax due to its throwback rule, the state does conform to the federal bonus depreciation allowance and federal net operating loss (NOL) provisions. The Sunflower State maintains a single point of sales tax administration for its state and local sales taxes, and its state and local sales tax bases largely match, with a couple of exceptions. Additionally, most of Kansas’ excise tax rates are relatively competitive compared to those in many other states.
Kansas’ property tax split roll ratio is fairly high, with commercial properties bearing a higher share of the property tax burden compared to residential properties, but by forgoing a capital stock tax and estate or inheritance tax, Kansas outperforms many of its peers on this component.

Several states have decoupled from GILTI by name rather than statutory citation. Lawmakers in those states should amend these statutes to ensure that their tax code does not accidentally incorporate a much more aggressive tax on international income than the tax from which they previously decoupled.
Public Law 86-272’s vague language, limited scope, and failure to evolve with modern commerce has rendered it increasingly ineffective, burdening businesses with heightened litigation and compliance challenges.
