Withholding Formula (Effective Pay Period 19, 2021)

  1. Subtract the nontaxable biweekly Thrift Savings Plan contribution from the gross biweekly wages.
  2. Subtract the nontaxable biweekly Federal Employees Health Benefits Plan payment(s) (includes dental and vision insurance program and Flexible Spending Account — health care and dependent care deductions) from the amount computed in step 1.
  3. Add the taxable biweekly fringe benefits (e.g., taxable life insurance) to the amount computed in step 2 to obtain the adjusted gross biweekly wages.
  4. Multiply the adjusted gross biweekly wages by the number of pay dates in the tax year to obtain the gross annual wages.
  5. Determine the exemption allowance by applying the following guideline and subtract this amount from the result of step 4 to compute the taxable income:

    Exemption Allowance = $2,250 x Number of Exemptions Claimed on Form K-4

  6. Apply the taxable income computed in step 5 to the following table to determine the annual Kansas tax withholding:

    Single Taxpayer:

    Annualized Gross Pay

    Standard Deduction Adjustment

    Over $0 but not over $3,500

    $0.00

    Over $3,500 but not over $18,500

    3.1% of excess over $3,500

    Over $18,500 but not over $33,500

    $465.00 plus 5.25% of excess over $18,500

    Over $33,500

    $1,252.50 plus 5.7% of excess over $33,500

    Married Taxpayer:

    Annualized Gross Pay

    Standard Deduction Adjustment

    Over $0 but not over $8,000

    3.1% of excess over $8,000

    Over $38,000 but not over $68,000

    $930.00 plus 5.25% of excess over $38,000

    Over $68,000

    $2,505.00 plus 5.7% of excess over $68,000

     

  7. Divide the annual Kansas income tax withholding calculated in step 6 by the number of pay dates in the tax year to obtain the biweekly Kansas tax withholding.
