Extra cash in your pocket every 2 weeks
With a $4,800 annual saving, a PAYG variation would give you an extra $185 every fortnight. This is a significant amount to put toward your mortgage offset or other investments.
Calculated using FY 2024-25 Stage 3 tax brackets.
A PAYG (Pay As You Go) Withholding Variation, formerly known as a Section 15-15 application, is a powerful cash-flow management tool for Australian taxpayers, particularly those with significant investment-related deductions. Normally, employers withhold tax from your salary based on your gross income, ignoring any potential deductions you might claim at the end of the financial year. For property investors with negatively geared assets, this often results in a large tax refund in July, but tighter cash flow throughout the year. A PAYG Variation allows you to apply to the ATO to reduce the amount of tax withheld from your regular pay cycle. By 'bringing forward' your expected tax refund and receiving it in small increments every payday, you can use that extra cash to pay down mortgage interest, cover investment expenses, or invest elsewhere. This strategy is highly favored by sophisticated Australian investors who prefer having their money in their own offset accounts rather than giving the ATO an interest-free loan for twelve months. It's important to understand that a variation doesn't change your total tax liability—it simply changes the timing of when you pay (or don't pay) that tax.
Our PAYG Variation Estimator works by calculating the difference between your standard tax liability and your projected liability after accounting for investment losses or other significant deductions. First, we calculate the 'Standard Withholding' on your gross annual salary using the current Australian tax brackets (including Medicare Levy). Next, we calculate the 'Adjusted Taxable Income' (Gross Salary - Expected Deductions/Losses). We then compute the 'New Estimated Tax' on this lower figure. The difference between the Standard Withholding and the New Estimated Tax represents your 'Potential Cash Flow Boost.' To find the impact per pay cycle, we divide this boost by the number of remaining pay periods in the financial year. For example, if you have a $10,000 loss and are in the 37% tax bracket, your total tax saving is $3,700. If you apply for a variation at the start of the financial year, you would receive approximately $142 extra in your fortnightly paycheck. The ATO typically requires you to demonstrate that your expected refund will be significant before approving a variation, usually where the tax to be withheld is expected to be more than $500 above the final liability.
PAYG Variations expire every year on June 30th. To maximize the cash flow benefit, experts recommend submitting your application to the ATO in May or June for the upcoming financial year. If you apply mid-year, the ATO will spread the remaining benefit over the fewer pay cycles left, resulting in a larger 'per-pay' jump but a shorter duration.
When submitting a variation to the ATO, it is critical to be conservative with your estimates. If you over-estimate your deductions and under-pay your tax during the year, you may end up with a surprise tax bill and potential 'GIC' (General Interest Charge) penalties from the ATO. Most advisors suggest estimating your losses at 80-90% of what you actually expect to ensure a small buffer.
The most effective way to use a PAYG variation is to redirect the 'extra' cash flow directly into a mortgage offset account. Because Australian mortgages calculate interest daily, having that extra $200-$400 a month hitting your account 12 months earlier than a standard refund can save you thousands of dollars in interest over the life of your loan.
To apply for a real variation, you'll need estimates of your rental income, interest expenses, rates, and depreciation. Use your previous year's tax return and your latest bank statements to ensure the 'Expected Loss' you enter in this calculator is based on realistic, defensible data.
The fastest way to lodge a PAYG Withholding Variation is via your MyGov account linked to the ATO. It is generally processed much faster than paper applications. Once approved, the ATO will send a notice directly to your employer's payroll department to adjust your withholding.
If the RBA increases interest rates and you have a variable-rate investment loan, your investment loss may increase significantly. This is a perfect time to use this estimator to see if you should update your variation to further reduce your tax withholding and protect your cash flow.
Sarah earns $110,000 and has a rental property that loses $12,000 a year after interest and expenses. Normally, she would wait until July for a $4,000 refund. By using a PAYG variation, she received an extra $155 in her fortnightly pay. She put this directly into her home loan offset, saving her $450 in interest charges over the year.
Mark earns $190,000 and is in the top 45% tax bracket. He has a portfolio of properties with combined losses of $30,000. This calculator showed he was entitled to a $13,500 tax saving. Instead of a lump sum, he received $519 extra every fortnight, which he used to fund the deposit for his next investment property sooner.
Elena realized in January that her deductions were going to be much higher than planned. Because there were only 6 months left in the financial year, her approved variation resulted in a 'double boost' to her remaining paychecks, providing $400 extra per fortnight until June 30th, providing urgent relief during a period of high expenses.
