Fortnightly Tax Calculator Australia

Fortnightly tax in Australia is calculated by your employer using the ATO's PAYG withholding schedules. The calculation takes your fortnightly gross income, projects it to an annual equivalent (by multiplying by 26), applies the relevant tax rates and thresholds, and then divides the annual tax by 26 to determine how much tax to withhold each fortnight. This calculation also includes the Medicare levy and adjustments for HELP debt or tax offsets you may be eligible for.

The amount of tax you'll pay on your fortnightly salary depends on your annual income level and various personal circumstances. For example, if you earn $2,500 per fortnight (about $65,000 annually) and claim the tax-free threshold, you'll pay approximately $410-$450 in tax per fortnight, including the Medicare levy. However, this can vary based on whether you have a HELP debt, claim tax offsets, or have other income sources. Use our calculator for an accurate estimate based on your specific situation.

The main difference between fortnightly and weekly tax calculations is the pay frequency. While the underlying tax rates and formulas are the same, a fortnightly calculation applies to 26 pay periods per year, while a weekly calculation applies to 52 pay periods. If your annual salary is the same, the fortnightly tax withholding will be approximately double the weekly amount, and the annual total tax paid should be identical. Some employers may slightly adjust withholding to account for the exact number of working days in a year.

Generally, no special adjustments are needed for fortnightly pay compared to other pay frequencies. The ATO provides employers with specific tax tables for different pay frequencies, including fortnightly. However, if you have multiple jobs, additional income sources, or expect to earn significantly more or less during part of the year, you might want to consider adjusting your withholding by completing a PAYG withholding variation form to avoid over or under-paying tax throughout the year.

No, you won't pay more tax annually if you're paid fortnightly instead of monthly. The total annual tax you pay is based on your total annual income, not how frequently you receive it. The ATO's withholding schedules are designed to ensure that the same annual income results in the same annual tax, regardless of whether it's paid weekly, fortnightly, or monthly. However, the timing of when that tax is withheld differs, which can affect your cash flow throughout the year.
