Schedule 1 – Statement of formulas for calculating amounts to be withheld

This schedule applies to withholding payments covered by Subdivisions 12-B (except sections 12-50 and 12-55), and 12-D of Schedule 1 to the TAA.

The amounts, formulas and procedures in this schedule were last updated on 1 July 2024.

About this schedule

Amounts to be withheld from payments made weekly, fortnightly, monthly and quarterly, as set out in the relevant PAYG withholding tax table at ato.gov.au/taxtables, can be calculated using the formulas and coefficients contained in this schedule.

Using this schedule

If you develop your own payroll or accounting software package, this schedule provides the formulas and coefficients you will need to calculate the amounts to be withheld from payments made on a weekly, fortnightly, monthly or quarterly basis.

Separate scales apply to:

• foreign residents
• employees who have claimed or not claimed the tax-free threshold
• employees claiming a full or half-exemption from the Medicare levy.

To assist employers who don't have a software package, our website ato.gov.au provides the following tools which are based on the formulas in this schedule:

• tax withheld calculator
• tax tables.

Payments covered include:

• salary, wages, allowances and leave loading paid to employees
• paid parental leave
• directors' fees
• salary and allowances paid to office holders (including members of parliament, statutory office holders, defence force members and police officers)
• payments to labour-hire workers
• payments to religious practitioners
• government pensions
• government education or training payments
• compensation, sickness or accident payments that are calculated at a periodical rate and made because a person is unable to work (unless the payment is made under an insurance policy to the policy owner).

Do not use this schedule for payments made to individuals employed under a working holiday makers visa. You must use Schedule 15 - Tax table for working holiday makers for all payments made to them, including lump sum payments.

Software

Payroll or accounting software written in accordance with the formulas in this schedule should be tested for accuracy against the 'Sample data' section in this schedule.

The results obtained when using the coefficients in this schedule may differ slightly from the sums of the amounts shown in the PAYG tax tables at ato.gov.au/taxtables. The differences result from the rounding of components. Withholding calculated using either method is accepted.

Other statements of formulas

Statements of formulas for other classes of payees are also available. These include:

• Schedule 8 - Statement of formulas for calculating study and training support loans components
• Schedule 2 - Tax table for individuals employed in the horticultural or shearing industry
• Schedule 3 - Tax table for actors, variety artists and other entertainers
• Schedule 9 - Tax table for seniors and pensioners
• Schedule 15 - Tax table for working holiday makers.

Coefficients for calculation of amounts to be withheld (withholding amounts) from weekly payments

Where the tax-free threshold is not claimed in Tax file number declaration – Scale 1

Where the employee claimed the tax-free threshold in Tax file number declaration – Scale 2

Foreign residents – Scale 3

Where a tax file number (TFN) was not provided by employee – Scale 4

Where the employee claimed the FULL exemption from Medicare levy in Medicare levy variation declaration – Scale 5

Where the employee claimed the HALF exemption from Medicare levy in Medicare levy variation declaration – Scale 6

Notes

1.         Scale 1 contains a negative value for one of the b coefficients. This is intentional.
2.         If you have 27 fortnightly, or 53 weekly pays in a financial year, refer to withholding additional amounts from employee earnings section.
3.         Scales 1, 2, 3, 5 and 6 may be applied only where employees have provided their TFN.
4.         For scale 4 no coefficients are necessary. To calculate withholding, apply the tax rate to earnings, ignoring any cents in earnings and in the withholding result.
5.         Scale 1 and 2 apply whether or not the employee is entitled to any leave loading.
6.         Tax offsets may be allowed only where scales 2, 5 or 6 are applied.
7.         Scale 1, 2, 4 and 6 incorporate the Medicare levy. Scale 4 incorporates the Medicare levy for residents only.
8.         For scale 2 no Medicare levy is payable by a person whose taxable income for the year is $26,000 ($500 per week) or less. Where the taxable income exceeds $26,000 but is less than $32,500 ($625 per week), the levy is shaded in at the rate of 10% of the excess over $26,000. Where a person’s taxable income is $32,501 ($625 per week) or more, Medicare is levied at the rate of 2% of total taxable income.
9.         The Medicare levy is also shaded in for scale 6. The Medicare levy parameters for scales 2 and 6 are as follows:

Using a formula

Overview

The formulas comprise linear equations of the form y = ax − b, 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 – see 'Working out the weekly earnings').

The formulas relate only to the calculation of withholding amounts before any tax offsets and Medicare levy adjustments are allowed. For instructions on the treatment of tax offsets and Medicare levy adjustments, refer to the sections on 'Tax offsets' and 'Medicare levy adjustment' in this schedule.

Sample data to verify that the software program is calculating the correct withholding amounts and Medicare levy adjustments has been provided in this schedule.

Withholding amounts calculated using these formulas may vary slightly to those calculated using the method set out in the footnote to the appropriate PAYG withholding tax table at ato.gov.au/taxtables. This applies if earnings exceed $3,400 weekly or $6,800 fortnightly.

Rounding of withholding amounts

Withholding amounts calculated as a result of applying the above formulas are rounded to the nearest dollar. Values ending in 50 cents are rounded to the next higher dollar. Do this rounding directly – that is, do not make a preliminary rounding to the nearest cent.

Use these rounding rules across all scales except scale 4 (where employee does not provide a TFN). For scale 4, cents are ignored when applying the tax rate to earnings and when withholding amounts are calculated.

When there are 53 pays in a financial year

In some years, you may have 53 pays instead of the usual 52. As this schedule is based on 52 pays, the extra pay may result in insufficient amounts being with
