Federal Budget 2026: What the Proposed Tax Changes Could Mean for Property Investors

OUR FRIENDS AT DUO TAX HAVE PROVIDED AN INSIGHTFUL ANALYSIS OF THE ANNOUNCED CHANGES TO PROPERTY TAX.

THEIR ARTICLE IS REPRODUCED HERE.

The Federal Budget 2026 includes proposed tax changes from the federal government that could affect Australian property investors, homeowners, and individuals.

Key announcements focus on capital gains tax, negative gearing, new build investment properties, and future tax records. For investors, these changes may affect how primary production income and residential rental losses are treated, how net capital gains are calculated, and whether a property’s market value needs stronger evidence.

Many measures are still proposals and have not yet become law. Even so, investors should understand what may change, when the rules may start, and how the difference between a new build and an established residential property could affect future returns.

This article explains the key proposed changes in simple terms, with a focus on what they could mean for property investors.

Federal Budget 2026 Key Takeaways

The Federal Budget 2026 proposes several comprehensive tax reform changes that could reshape how investors assess property, tax deductions, and future capital gains.

Key takeaways include:

• The current 50 per cent capital gains tax discount may be replaced with cost base indexation from 1 July 2027.
• A 30 per cent minimum tax rate may apply to some net capital gains.
• Negative gearing may be limited for certain established residential properties.
• New build properties may receive more favourable tax treatment as a development tax incentive.
• Property investors may need stronger records to support market value, ownership dates, improvement costs, and future capital gains tax calculations.
• A tax depreciation schedule may remain important for claiming eligible depreciation deductions.
• The proposed changes are not yet law and may change before they take effect.

These measures could affect cash flow, buying decisions, selling strategies, and long-term tax planning for Australian property investors.

Theoretically, under the proposed tax reform, investors may be able to pool rental losses across different properties. These pooled losses could reduce future rental income or capital gains, which may make a tax depreciation schedule more valuable to track eligible deductions and maximise the pooled losses.

What Are the Proposed Capital Gains Tax Changes?

One of the biggest Federal Budget 2026 announcements relates to capital gains tax.

Under the current tax system, many individuals can reduce a capital gain by 50 per cent when they sell an eligible asset held for more than 12 months. This is known as the 50 per cent capital gains tax discount or luxury car tax threshold discount.

The Budget proposes to replace this discount with cost base indexation from 1 July 2027. Instead of halving the gain, investors may adjust the original cost base of an asset to reflect inflation. This could change how much tax paid applies when an investment property is sold.

A 30 per cent minimum tax rate may also apply to some capital gains. This means investors may need to compare the final income tax outcome under the proposed rules before selling.

For properties owned before 1 July 2027 and sold after that date, the gain may need to be split between the pre-change and post-change periods. This is where accurate records and reliable market value evidence may become more important.

Why Property Valuations May Become More Important

If the proposed capital gains tax changes become law, property investors may need stronger evidence to support future capital gains tax calculations.

For properties owned before 1 July 2027 and sold after that date, investors may need to separate the gain made before the new rules from the gain made after the new rules. This may require a reliable estimate of the property’s market value at the changeover date.

A capital gains tax valuation or retrospective property valuation may help support that figure. It can provide independent evidence of market value, which may be useful when calculating capital gains tax, reviewing cost base records, or preparing information for an accountant.

This is especially important for investors who own long-held properties, renovated properties, or assets with limited purchase records. Clear valuation evidence may reduce guesswork and support better tax reporting if the proposed rules proceed.

How Negative Gearing May Change Under the Federal Budget 2026

The Federal Budget 2026 also proposes changes to negative gearing for residential property investors.

Negative gearing occurs when the costs of holding an investment property, such as loan interest payments, repairs, rates, and other expenses, are higher than the rental income it earns. Under current rules, many investors can use that loss to reduce their taxable income.

Under the proposal, negative gearing may be limited for certain established residential properties acquired after budget night. Instead of offsetting rental losses against salary or business income, investors may need to carry forward those losses and use them against future rental income or capital gains.

This could affect cash flow for investors who rely on tax refunds to help cover holding costs. It may also make the difference between an established property and a new build investment property more important when comparing future returns.

Existing property owners may receive grandfathering treatment, but investors should wait for final legislation before making major decisions.

Why New Builds May Receive Different Tax Treatment

The Federal Budget 2026 places more importance on whether a property qualifies as a new build.

Under the proposed rules, new residential properties may continue to receive more favourable tax treatment than established properties. This may include continued access to negative gearing and, in some cases, different options for calculating capital gains tax.

The policy aims to support housing supply by encouraging investment in newly built homes through a development tax incentive. For investors, this means the tax outcome may depend on the type of property they buy, when they buy it, and whether it meets the final definition of a new build.

This makes due diligence more important. Before buying, investors may need to confirm whether a property is treated as new, substantially renovated, or established under the final rules.

What the Federal Budget 2026 Could Mean for Property Investors

For property investors, the Federal Budget 2026 may affect buying decisions, cash flow, and long-term tax planning.

If negative gearing changes proceed, some investors may find established properties less attractive because rental losses may no longer reduce salary or business income straight away. This could make holding costs harder to manage, especially in the first few years of ownership.

New builds may become more appealing if they keep access to more favourable tax treatment. However, investors should still compare the full picture, including purchase price, rental yield, depreciation deductions, loan costs such as interest payments, and expected capital growth.

A tax depreciation schedule may still help investors claim eligible deductions for capital works and plant and equipment. Accurate property records, including purchase costs, improvement costs, and valuation evidence, may also become more important if capital gains tax rules change.

Other Federal Budget 2026 Measures Individuals Should Know

While property tax changes have received strong attention, the Federal Budget 2026 also includes proposed measures that may affect individuals, working Australians, and small business owners.

These may include changes to personal income tax deductions, tax offsets such as the working Australians tax offset, Medicare levy thresholds, trust taxation including discretionary trusts, and small business instant tax deduction write-offs. Some measures aim to simplify tax claims, while others may change how income, deductions, or investment structures are treated.

For individuals, this means the Budget may affect more than property decisions. It could influence yearly tax planning, record-keeping, and how taxpayers manage work-related expenses.

For small business owners and investors, proposed write-off rules and trust tax changes may also affect future planning. As with the property measures, these changes are not yet law, so taxpayers should seek advice before changing their strategy.

Are the Federal Budget 2026 Changes Law Yet?

The Federal Budget 2026 changes are still proposals. They have not yet passed into law.

This is important because the final rules may change before they apply. Dates, eligibility rules, exemptions, and calculation methods may also become clearer once legislation is released.

Property investors should not rely on headlines alone when making major buying, selling, or tax planning decisions. Instead, they should monitor updates, keep accurate records, and speak with a qualified tax adviser before acting.

For now, the Budget gives investors a clear signal about the direction of future tax policy, especially around capital gains tax, negative gearing, new builds, and property reporting.

Final Thoughts: What Should Investors Do Next?

The Federal Budget 2026 may change how property investors approach tax planning, cash flow, and future selling decisions.

While the proposed changes are not yet law, investors can still take practical steps now. Start by checking whether your property is a new build or an established residential property. Review your purchase records, improvement costs, loan documents, and rental income records. These details may become more important if the capital gains tax or negative gearing rules change.

Investors who plan to sell after 1 July 2027 may also need stronger evidence of market value to support future capital gains tax calculations. A capital gains tax valuation may help provide that evidence.

A tax depreciation schedule may also help identify eligible depreciation deductions during ownership, which can support cash flow and reduce taxable income where the rules allow.

If you own an investment property, now is a good time to review your records and understand how the proposed Federal Budget 2026 changes could affect your future tax position.
