            (b) Monthly wages. If the employee is paid on a monthly basis, his monthly salary multiplied by twelve then divided by fifty-two.

            (c) Annual wages. If the employee is employed at an annual salary, his annual salary divided by fifty-two.

            (d) Other wages. If the employee is employed on a unit, piecework, commission, or other basis, his gross earnings from the employer for the twenty-six week period immediately preceding the accident divided by the number of days the employee actually worked for the employer during said twenty-six week period and multiplied by the average number of days worked per week; however, if such an employee has worked for the employer for less than a twenty-six week period immediately preceding the accident, his gross earnings from the employer for the period immediately preceding the accident divided by the number of days the employee actually worked for the employer during said period and multiplied by the average number of days worked per week.

            (e) Exceptions. For municipal police officers, additional compensation paid by the state pursuant to R.S. 40:1667.3 shall not be included in the calculation and computation of total salary or average weekly wage to the extent such officer continues to receive such additional compensation during the period of his disability.

            (f) Income tax. In the determination of "wages" and the average weekly wage at the time of the accident, no amount shall be included for any benefit or form of compensation which is not taxable to an employee for federal income tax purposes; however, any amount withheld by the employer to fund any nontaxable or tax-deferred benefit provided by the employer and which was elected by the employee in lieu of taxable earnings shall be included in the calculation of the employee's wage and average weekly wage including but not limited to any amount withheld by the employer to fund any health insurance benefit provided by the employer and which was elected by the employee in lieu of taxable earnings shall be included in the calculation of the employee's wage and average weekly wage.

            (g) Date of accident.
