  • Coefficients to work out the weekly amounts to withhold including the SFSS component

    Attention

    Warning:

    This information may not apply to the current year. Check the content carefully to ensure it is applicable to your circumstances.

    End of attention

    Your employee’s total withholding, including the SFSS component, can be calculated using the formula and coefficients stated below.

    Using a formula

    The formulas comprise linear equations of the form y = axb, where:

    • y is the weekly withholding amount expressed in dollars
    • x is the number of whole dollars in the weekly earnings plus 99 cents
    • a and b are the values of the coefficients for each set of formulas for each range of weekly earnings (or, in the case of fortnightly, monthly or quarterly earnings, the weekly equivalent of these amounts).

    If two employees are taxed using a particular scale (for example, scale 2) but only one of them has a Financial Supplement debt, you will need to set up two separate scales in your payroll system. One scale will need to incorporate the SFSS component and one will not – for example, name one ‘scale 2’ and the other ‘scale 22’.

    The SFSS component does not apply if the employee has not provided a tax file number (TFN).

    For scales without the SFSS component, refer to Statement of formulas for calculating amounts to be withheld.

    Withholding amounts including the SFSS component worked out using the coefficients may differ slightly from the sums of the amounts shown in the PAYG and SFSS tax tables. The differences result from the rounding of components.
