Withholding Tax

Home : Business : Withholding Tax


Who Is Required To Withhold

Every employer who has resident or nonresident employees performing services (except employees exempt from income tax withholding) within Louisiana is required to withhold Louisiana income tax based on the employee's withholding exemption certificate. Wages of Louisiana residents performing services in other states are subject to withholding of Louisiana income tax if the wages are not subject to withholding of net income tax by the state in which the services are performed.



Who Must File

Every employer who withheld or was required to withhold income tax from wages must file the employer's return of Louisiana state income tax withheld. Each employer who withholds from the combined wages of all employees less than $500 per month is required to file on a quarterly basis. Each employer who withholds from the combined wages of all employees at least $500 but less than $2,000 per month is required to file on a monthly basis. Each employer who withholds from the combined wages of all employees $2,000 per month or more must file on a semimonthly basis.



Rates of Tax

Louisiana Administrative Code 61:I.1501 provides income tax withholding tables to be used for computing the proper amount to be withheld based on the employee's income, filing status, and number of exemptions. Acts 2008, No. 396, amended R.S. 47:32(A) to reduce the income tax rates and brackets, and to provide that the individual income tax withholding tables provided by LAC 61:I.1501 be amended effective July 1, 2009. The income tax withholding formulas prescribed by LAC 61:I.1501.D as amended LR 35:256 (February 2009) contained errors that will be corrected by amending the rule. The corrected formulas are as follows:

               
  D. Income Tax Withholding Formulas.
    The overall structure of the formulas used to compute the withholding tax is to calculate the tax on the total wage amount, and then subtract the amount of tax calculated on the personal exemptions and dependency credits the taxpayer claims for withholding purposes. The correct withholding formula depends upon the number of personal exemptions claimed and annual wages.
 
      1. Withholding Formulas for Single or Married Taxpayers Claiming 0 or 1 Personal Exemption:
 
          W is the withholding tax per pay period.
          S is employee’s salary per pay period for each bracket.
          X is the number of personal exemptions; X must be 0 or 1.
          Y is the number of dependency credits; Y must be a whole number that is 0 or greater.
          N is the number of pay periods.
 
          A is the effect of the personal exemptions and dependency credits equal to or less than $12,500;
            A = .021 (((X * 4500) + (Y * 1000)) ÷ N).
 
          B is the effect of the personal exemptions and dependency credits in excess of $12,500;
            B = .016 ((((X * 4500) + (Y * 1000)) - 12,500) ÷ N).
 
          If annual wages are less than or equal to $12,500, Then
            W = .021 (S) - (A + B).
 
          If annual wages are greater than $12,500, but less than or equal to $50,000, Then
            W = .021 (S) + .0160 (S - (12,500 ÷ N)) - (A + B).
 
          If annual wages are greater than $50,000, Then
            W = .021 (S) + .0160 ( S - (12,500 ÷ N)) + .0135 (S - (50,000 ÷ N)) - (A + B).
 
      2. Withholding Formulas for Married Taxpayers Claiming 2 Personal Exemptions:
 
          W is the withholding tax per pay period.
          S is the employee’s salary per pay period for each bracket.
          X is the number of personal exemptions. X must be 2.
          Y is the number of dependency credits. Y must be 0 or greater.
          N is the number of pay periods.
 
          A is the effect of the personal exemptions and dependency credits equal to or less than $25,000;
            A = .021 (((X * 4500) + (Y * 1000)) ÷ N).
 
          B is the effect of the personal exemptions and dependency credits in excess of $25,000;
            B = .0165 ((((X * 4500) + (Y * 1000)) - 25,000) ÷ N).
 
          If annual wages are less than or equal to $25,000, Then
            W = .021 (S) - (A + B).
 
          If annual wages are greater than $25,000, but less than or equal to $100,000, Then
            W = .021 (S) + .0165 (S - (25,000 ÷ N)) - (A + B).
 
          If annual wages are greater than $100,000, Then
            W = .021 (S) + .0165 (S - (25,000 ÷ N)) + .0135 (S - (100,000 ÷ N)) - (A + B).
 
      3. If any of the variables in the formula are negative, the negative variable should be considered zero.
               
  NOTE:  Any taxpayer may use the single taxpayer withholding formulas; however, only married taxpayers who will file a joint income tax return may use the married taxpayer formulas.
               
  Examples of the withholding formulas:
 
    Example 1:
 
      Taxpayer is claiming 1 personal exemption and 2 dependency credits. Taxpayer is paid $700 weekly (52 pay periods, $36,400 annual salary).
 
        The formula to use in this example is:
 
          W is the withholding tax per pay period.
          S is the employee’s salary per pay period for each bracket.
          X is the number of personal exemptions; X must be 0 or 1. (A personal exemption is equal to $4,500.)
          Y is the number of dependency credits; Y must be a whole number that is 0 or greater. (A dependency credit is equal to $1,000.)
          N is the number of pay periods.
 
          A = .021 (((X * 4,500) + (Y * 1,000)) ÷ N).
 
          B = .016 ((((X * 4,500) + (Y * 1,000)) - 12,500) ÷ N).
 
          W = .021 (S) + .0160 (S - (12,500 ÷ N)) - (A + B).
 
        The calculation for this example:
 
          S = $700
          X = 1
          Y = 2
          N = 52
 
          A = the effect of the personal exemptions and dependency credits equal to or less than $25,000;
            A = .021 (((1 * 4,500) + (2 * 1,000)) ÷ 52)
            A = .021 ((4,500 + 2,000) ÷ 52)
            A = .021 (6,500 ÷ 52)
            A = .021 (125.00)
            A = 2.63
 
          B = the effect of the personal exemptions and dependency credits in excess of $25,000;
            B = .016 ((((1 * 4,500) + (2 * 1,000)) - 12,500) ÷ 52)
            B = .016 (((4,500 + 2,000) - 12,500) ÷ 52)
            B = .016 ((6,500 - 12,500) ÷ 52)
            B = .016 (0 ÷ 52)
            B = .016 (0)
            B = 0
 
          Remember, if any of the variables in the formula are negative, the negative variable should be considered zero.
 
          W = the withholding tax per pay period;
            W = .021 (700) + .0160 (700 - (12,500 ÷ 52)) – (A + B)
            W = 14.70 + .0160 (700 - 240.38) – (2.63 + 0)
            W = 14.70 + .0160 (459.62) – 2.63
            W = 14.70 + 7.35 – 2.63
            W = $19.42
 
    Example 2:
 
      Taxpayer is claiming 2 personal exemptions and 3 dependency credits. Taxpayer is paid $4,600 bi-weekly (26 pay periods, $119,600 annual salary).
 
        The formula to use in this example is:
 
          W is the withholding tax per pay period.
          S is the employee’s salary per pay period for each bracket.
          X is the number of personal exemptions. X must be 2. (A personal exemption is equal to $4,500.)
          Y is the number of dependency credits. Y must be 0 or greater. (Each dependency credit is equal to $1,000.)
          N is the number of pay periods.
 
          A = .021 (((X * 4,500) + (Y * 1,000)) ÷ N).
 
          B = .0165 ((((X * 4,500) + (Y * 1,000)) - 25,000) ÷ N).
 
          W = .021( S ) + .0165 (S - (25,000 ÷ N)) + .0135 (S - (100,000 ÷ N)) - (A + B).
 
        The calculation for this example:
 
          S = $4,600
          X = 2
          Y = 3
          N = 26
 
          A = the effect of the personal exemptions and dependency credits equal to or less than $25,000;
            A = .021 (((2 * 4,500) + (3 * 1,000)) ÷ 26)
            A = .021 ((9,000 + 3,000) ÷ 26)
            A = .021 (12,000 ÷ 26)
            A = .021 (461.54)
            A = 9.69
 
          B = the effect of the personal exemptions and dependency credits in excess of $25,000;
            B = .0165 ((((2 * 4,500) + (3 * 1,000)) - 25,000) ÷ 26)
            B = .0165 (((9,000 + 3,000) – 25,000) ÷ 26)
            B = .0165 ((12,000 – 25,000) ÷ 26)
            B = .0165 (0 ÷ 26)
            B = .0165 (0)
            B = 0
 
          Remember, if any of the variables in the formula are negative, the negative variable should be considered zero.
 
          W = the withholding tax per pay period;
            W = .021 ( 4,600 ) + .0165 (4,600 - (25,000 ÷ 26)) + .0135 (4,600 - (100,000 ÷ 26)) - (A + B)
            W = 96.60 + .0165 (4,600 – 961.54) + .0135 (4,600 – 3,846.15) - (9.69 + 0)
            W = 96.60 + .0165 (3,638.46) + .0135 ( 753.85 ) – 9.69
            W = 96.60 + 60.03 + 10.18 – 9.69
            W = $157.12
