Negative Gearing Australia 2025-26: Complete Investor Guide

How Negative Gearing Actually Works

Mechanically, it's straightforward. Australia allows taxpayers to deduct the expenses of earning assessable income. If you earn $30,000 of rent and spend $45,000 on loan interest, rates, insurance, and management, you have a $15,000 rental loss. That loss reduces your assessable income from other sources — your salary, your business profit, your interest income — lowering your total tax bill for the year.

The tax benefit is the rental loss multiplied by your marginal tax rate. If the $15,000 loss brings your taxable income down one bracket's worth of dollars, each of those dollars saves you tax at your highest (marginal) rate.

There are three categories of deductible expense:

• Immediately deductible — interest, rates, insurance, management, repairs, strata, land tax, advertising, cleaning. Claimed in full in the year incurred.
• Depreciation — decline in value of the building (Div 43, 2.5% per year for 40 years on post-1987 construction) and plant & equipment (Div 40, faster rates via prime cost or diminishing value).
• Borrowing costs — loan application fees, LMI, mortgage broker fees. Claimed over 5 years or the loan term, whichever is shorter.

Tax Benefit by Marginal Rate (2025-26)

Your marginal tax rate determines the size of the benefit. Higher earners get larger tax savings from the same rental loss.

The concentration effect: a high-income professional earning $250,000 on the top bracket saves $4,700 on every $10k of rental loss. A public servant on $80,000 saves only $3,200. The same property with the same expenses produces a different after-tax cost depending on who owns it — which is why structuring ownership toward the higher-earning spouse (when legally sound) is a common strategy.

Cash-Negative vs Tax-Negative (The Most Important Distinction)

A property can be cash-negative, tax-negative, both, or neither. Understanding the difference is the single most important insight in negative gearing.

• Cash-negative: rent received is less than cash expenses (interest + rates + insurance + management + repairs). You're out of pocket every month.
• Tax-negative: total deductions (cash expenses + depreciation) exceed rent. You report a loss on your tax return.

A newer property with high depreciation ($8k-$12k per year) can be tax-negative but cash-positive: you're slightly ahead in cash each month, but the tax return shows a loss because depreciation is a deductible non-cash expense. You get a tax refund and a cash-positive rental. This is often the sweet spot.

An older property in a high-interest-rate environment is usually cash-negative by a wide margin, with only modest depreciation. The tax refund might offset 30–40% of the cash loss, leaving you genuinely out of pocket.

Worked Example: $800k Brisbane Property

Consider a professional earning $150,000 (marginal rate 39% including Medicare) who buys an $800,000 investment property in Brisbane. Rent is $600/week with 50 weeks rented annually. Loan of $640,000 at 6.2% interest-only.

The headline $18,080 cash loss becomes $7,421 after the tax refund — the investor holds the asset at $143/week of out-of-pocket expense. Over 10 years with rent growth and capital growth of 4–5%, this typically breaks even on cashflow by year 6–7 and produces significant equity growth.

Depreciation: The Secret Weapon

Depreciation is where sophisticated investors separate from casual landlords. There are two types:

Division 43 (Capital Works)

The building structure — walls, roof, floors, permanent fixtures — depreciates at 2.5% per year over 40 years (for properties built after 1987). A $250,000 building cost produces $6,250 per year in non-cash deductions. Over 40 years, that's $250,000 of deductions for an investor who did nothing beyond keeping the roof on.

Division 40 (Plant & Equipment)

Carpets, blinds, ovens, hot water systems, air conditioning, dishwashers — each has its own effective life (5–15 years typically). You can choose the diminishing value method (faster deductions upfront) or prime cost (straight-line).

The 2017 second-hand rule

Since May 2017, you generally cannot claim Division 40 on previously used plant and equipment in residential property. New builds still qualify. This is why newer properties produce substantially larger depreciation claims than older ones — a factor often missed by buyers comparing "price per dollar of rent".

Getting a depreciation schedule

A quantity surveyor produces a depreciation schedule ($600–$1,000) documenting the depreciable components and annual claims over 40 years. The schedule is tax-deductible and typically pays for itself within the first year of deductions.

PAYG Variation: Getting the Refund in Your Pay

Most investors wait until they lodge their tax return (up to 12 months after the event) to receive the refund from negative gearing. This is a cashflow drag — the ATO holds your money interest-free.

The PAYG withholding variation (form NAT 2036) tells the ATO your expected rental loss for the coming year. Your employer reduces tax withheld from your pay accordingly. Instead of a $10,000 lump refund in October 2026, you receive approximately $200 extra in each fortnightly pay from 1 July 2025.

This is particularly useful when:

• The refund would materially help pay the mortgage (avoiding borrowing or dipping into savings)
• Your income and rental expenses are stable and predictable
• You want to avoid the ATO-held float for cashflow reasons

The variation is valid for one financial year. If your circumstances change significantly, update or withdraw it promptly — if you end up owing tax because you overclaimed, the ATO will reconcile at your next return.

How Negative Gearing Interacts with CGT

Annual tax benefits from negative gearing are only half the story. When you sell, CGT applies to the capital gain. Two interaction points matter:

Division 43 reduces cost base

Every dollar of Division 43 capital works deduction you've claimed reduces the property's CGT cost base on sale. A property bought for $500,000, held 10 years with $60,000 of Div 43 claimed, and sold for $900,000 produces:

• Naive gain: $900k − $500k = $400,000
• Actual taxable gain: $900k − ($500k − $60k) = $460,000 (cost base reduced)
• With 50% discount: $230,000 taxable
• Tax at 39% marginal: $89,700

The $60,000 of annual deductions produced roughly $23,000 of tax savings over 10 years — but the $60,000 cost base reduction adds $23,400 of extra CGT on sale. Net benefit: small. Div 43 is essentially a deferral, not a permanent tax saving.

Division 40 doesn't reduce cost base

Plant and equipment depreciation is permanent. The $30,000 you claimed on carpets, blinds, and appliances over 10 years produces $11,700 of tax savings with no CGT offset on sale.

50% CGT discount

Held for over 12 months and sold as an Australian resident, you get the 50% CGT discount. Combined with the fact that capital gains are often larger than the cumulative negative gearing benefits, the real driver of investor returns is capital growth — not annual tax refunds.

Reform Risk

Negative gearing is politically contested. The 2019 Labor proposal would have restricted it to new builds (not adopted — Labor lost the election). Occasional reviews since have revisited the topic without legislative change.

Plan for the current rules while acknowledging the tail risk. Two practical implications:

• Don't rely on negative gearing for cashflow. If the rule changes, you need an asset that stands on its own economics — meaning capital growth potential and/or a pathway to positive cashflow.
• Grandfathering is likely. Every serious proposal to restrict negative gearing has included grandfathering existing properties. Properties bought before a rule change would typically retain current treatment.

Strategic Planning

Buy the right kind of property

For the strategy to work, the property needs capital growth potential. A high-yield but low-growth regional property produces positive cashflow but minimal negative gearing. A low-yield capital city property needs the growth to justify the annual cashflow drag. Match the property to the strategy.

Structure ownership for the higher earner

If one spouse earns at 47% and the other at 32%, concentrating negative-geared property ownership on the higher earner captures 15% more tax benefit per dollar of loss. This must respect genuine ownership and funding — ATO can challenge sham arrangements.

Interest-only loans

Interest-only loans maximise deductible interest and preserve cashflow for other uses. Principal-and-interest loans accelerate equity but reduce annual deductions. Most sophisticated investors use interest-only on investment loans and principal-and-interest on their own home.

Use depreciation

A quantity surveyor's schedule costs $600–$1,000 and typically identifies $5,000–$12,000 of annual depreciation. The schedule is deductible. Skipping this step leaves money on the table every year.

Common Mistakes

• Chasing losses for tax savings. You're still down $7,000 in the example above, not up. The tax refund reduces the loss; it doesn't reverse it. Only capital growth makes the investment work.
• Claiming principal repayments. Only interest is deductible. Loan statements distinguish the two clearly — use them.
• Claiming improvements as repairs. Replacing a broken tap is a repair (deductible). Replacing the entire bathroom is a capital improvement (depreciable over its effective life, not immediately deductible).
• Not getting a depreciation schedule. $5,000+ of deductions left on the table every year because a quantity surveyor wasn't engaged.
• Forgetting the Div 43 cost-base reduction. Claiming Div 43 deductions for 10 years then being surprised by the CGT bill on sale.
• Applying for PAYG variation without updating. Rental income rose, expenses fell — now you're underpaying tax and will have a bill at year-end.
• Using negative gearing on a low-growth property. The tax refund has to be outweighed by capital growth for the strategy to deliver a positive return.
