Corporate Income Tax
For corporations whose business income is solely within state boundaries, the tax is 4% of net income. In addition, net income in excess of $50,000 is subject to a 3% percent surtax. For those corporations with business income both inside and outside the state, the net income attributed to the Kansas operation is based upon the percentage of the corporation’s business located in Kansas. A business’ tax obligation is determined by a three-factor formula using the proportion of sales, property and payroll in Kansas compared to total sales, property and payroll.
