Australian Tax Calculators for Property Investors, Individuals and Business Owners

Why Use Australian Tax Calculators?

Tax calculators can help simplify complex calculations and provide a starting point before seeking professional advice. Many Australians make financial decisions without fully understanding the possible tax or cashflow impact.

Using tax calculators may help with:

• Estimating capital gains tax before selling an asset
• Reviewing land tax exposure by state
• Estimating personal income tax
• Understanding possible HECS-HELP repayment obligations
• Checking Medicare levy estimates
• Reviewing investment property cashflow
• Comparing possible tax outcomes before making decisions
• Preparing better questions before a consultation
• Supporting tax planning and financial forecasting
• Identifying when personalised advice may be required

The ATO publishes Australian resident tax rates for income years up to 2025–26, but individual results can still vary depending on offsets, levies, deductions and personal circumstances. Users can review the ATO’s official Australian resident tax rates for current income tax rate information.

Capital Gains Tax Calculators

Capital gains tax can apply when an asset is sold for more than its cost base. This may include property, shares, crypto assets and other investments.

The Investax Calculator page currently includes:

• General Capital Gains Calculator
• Capital Gains Calculator for Trusts
• Capital Gains Tax Calculator for Shares
• Capital Gains Tax Calculator for Crypto

These calculators may help estimate the possible capital gains tax impact before selling or restructuring an investment.

Capital gains tax outcomes can depend on factors such as ownership period, discount eligibility, cost base, sale proceeds, asset type, tax residency and ownership structure. Professional advice should be obtained before making a major sale decision.

Land Tax Calculators by State

Land tax rules and thresholds can vary across Australian states and territories. Property investors should review potential land tax exposure before buying or holding investment property.

The Investax Calculator page currently includes state-based land tax calculators for:

• NSW Land Tax
• VIC Land Tax
• QLD Land Tax
• WA Land Tax
• SA Land Tax

Land tax can affect investment property cashflow, especially when a portfolio grows or when land is held through certain structures. Revenue NSW explains land tax as a state tax charged on the value of unimproved land, with thresholds and rates used to determine liability.

Property investors who need tailored support can review Investax’s investment property tax services for help with rental property tax, deductions, land tax planning, CGT and investment property structures.
