Withholding Formula (Effective Pay Period 05, 2020)

  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. Subtract the Standard Deduction of $2,200 from annualized gross pay in step 4 to determine annual net taxable income.
  6. If the annual net taxable income is less than $87,001, truncate (shorten) the annual net taxable income to the nearest $100 and then add $50. If the annual net taxable income is $87,001 or more, there is no adjustment to the annual net taxable income amount. For example, if the annual net taxable income is $23,324, truncate to $23,300 and add $50. The amount to be used in calculating the annual gross tax amount is $23,350.
  7. Apply the tax rates below to the annual net taxable income and subtract the minus adjustment amount. Round the result to the nearest whole dollar. This is the annual gross tax amount.

    Net Taxable Income:

    Amount of Tax:

    $0 but not over $4,600


    $4,600 but not over $9,100

    2.00% minus $91.98

    $9,100 but not over $13,700

    3.00% minus $182.97

    $13,700 but not over $22,600

    3.40% minus $237.77

    $22,600 but not over $37,900

    5.00% minus $421.46

    $37,900 but not over $80,801

    5.90% minus $762.55

    $80,801 but not over $81,801

    6.60% minus $1,243.40

    $81,801 but not over $82,801

    6.60% minus $1,143.40

    $82,801 but not over $84,101

    6.60% minus $1,043.40

    $84,101 but not over $85,201

    6.60% minus $943.40

    $85,201 but not over $86,201

    6.60% minus $843.40

    Over $86,201

    6.60% minus $803.40

  8. Determine the number of personal exemptions by applying the following guidelines:

    If the Employee Is Claiming Status As:

    Then the Personal Exemption Should Be:

    Single - Personal Exemption Code S


    Married - Personal Exemption Code M


    Married - Personal Exemption Code N


    Head of Household - Personal Exemption Code H


    Zero - Personal Exemption Code 0 (zero)


  9. Add the number of dependent exemptions claimed to the personal exemption(s) from the result in step 8 to compute the total withholding exemptions.
  10. Multiply the total number of withholding exemptions by $26.00 to determine the personal tax credit.
  11. Subtract the personal tax credit from the annual gross tax in step 7 to determine the annual net tax.
  12. Divide the annual Arkansas income tax withholding determined by the number of pay dates in the tax year to obtain the biweekly Arkansas income tax withholding.
