What Is Negative Gearing?
Negative gearing occurs when the costs of holding an investment exceed the income it generates - producing a net investment loss. In Australia, this net loss is deductible against all other income, including salary - reducing total taxable income and the associated tax payable.
- The basic mechanics: Investment property rental income: $28,000/year. Investment costs (mortgage interest + rates + insurance + agent fees + maintenance + depreciation): $43,000/year. Net loss: $15,000. This $15,000 reduces your taxable income
- Tax deduction at marginal rate: At 37% marginal rate, a $15,000 net rental loss reduces tax payable by $5,550. The 'cost' of carrying the loss is $15,000 - $5,550 = $9,450 cash out of pocket per year. The ATO effectively subsidises 37 cents of every dollar of loss
- The bet: Negative gearing only 'works' if the capital growth of the property exceeds the accumulated cash flow loss over the holding period. It is a bet that property prices will rise enough to justify the annual carrying cost
- Applies to all investments: Negative gearing is not limited to property. Margin loan interest on a share portfolio that exceeds dividend income, or any investment where costs exceed income, creates a negative gearing deduction. Property negative gearing is most common in Australia due to leverage accessibility
- Positive gearing: The opposite - where rental income exceeds all costs. The surplus is assessable income at your marginal rate. Less common in Australian capital city markets; more common in regional high-yield properties
- Neutral gearing: Where income exactly equals costs. No tax impact; pure capital growth investment
Calculating the True After-Tax Cash Flow
The negative gearing tax benefit is frequently misunderstood - it does not eliminate the cash outflow, it only reduces it. A precise calculation is essential before committing to a negatively geared investment.
- Gross rent: $550/week × 52 weeks × (1 - 4% vacancy rate) = $27,456/year
- Investment costs: Mortgage interest ($600,000 × 6.2%) = $37,200; property management 8.5% = $2,334; rates $2,000; insurance $1,200; maintenance $1,500; landlord insurance $400. Total cash costs: $44,634
- Depreciation (non-cash deduction): Quantity surveyor report for a property built 2010: Division 43 building allowance $4,500 + Division 40 plant/equipment $3,500 = $8,000 additional non-cash deduction
- Net taxable loss: $27,456 income - $44,634 cash costs - $8,000 depreciation = -$25,178 net loss
- Tax refund at 37%: $25,178 × 37% = $9,316
- True annual cash outflow: Cash costs ($44,634) - rent ($27,456) - tax saving ($9,316) = $7,862 per year out of pocket
- Per week cost: $7,862 ÷ 52 = $151/week true cost of holding the $700,000 investment property
- Break-even capital growth needed: To recoup $7,862/year cash outflow, the property needs to appreciate by at least $7,862/year (1.12% on $700,000). Australian capital city properties have historically grown at 6-8%/year - well above break-even. But past performance is not guaranteed
What Is Deductible and What Is Not
Claiming incorrect deductions on an investment property is a primary ATO audit trigger. Understanding which costs are deductible (and when) prevents costly errors.
- Deductible immediately: Mortgage interest (investment portion only), property management fees, council rates, water rates and usage (if landlord pays), insurance, repairs and maintenance (like-for-like restoration), pest inspection, advertising for tenants, stationery and postage, depreciation (via QS report)
- Deductible over time (capital works): Improvements - adding a deck, renovating a kitchen, extensions - are capital works deducted at 2.5% per year over 40 years (Division 43), not immediately. A $20,000 kitchen renovation = $500/year deduction for 40 years
- Not deductible: Purchase costs (stamp duty, conveyancing, building inspections - these form part of the cost base for CGT). Mortgage principal repayments. Costs of periods where the property is not available to rent (holidays, vacant between owners). Expenses incurred before the property is first available to rent
- Borrowing costs: Loan establishment fees, mortgage broker fees, lenders mortgage insurance (LMI) - deducted over 5 years or the loan term (whichever is shorter) if over $100. Under $100 - deductible immediately
- Interest only vs principal and interest: Investors often use interest-only loans to maximise the deductible interest component. Interest on an I/O loan is 100% deductible. P&I loan: only the interest component is deductible - the principal repayment is not
- Mixed use properties: If you use the investment property personally (holiday home, Airbnb with personal stays) - deductions must be apportioned to the income-producing period only
Depreciation: The Non-Cash Deduction That Changes the Numbers
Depreciation is a deduction for the wear and tear on a property's structure and fittings - crucially, it requires no cash outflow. This non-cash deduction significantly improves the after-tax position of many negatively geared properties.
- Quantity Surveyor (QS) report: The ATO requires a QS report (prepared by a registered quantity surveyor) to claim Division 40 plant and equipment depreciation. Cost: $500-$800 - deductible in the year incurred
- Division 43 - building allowance: 2.5% of the construction cost per year, for buildings constructed after 16 September 1987 (residential) or 27 February 1992 (commercial). On a $500,000 construction cost: $12,500/year deduction for 40 years
- Division 40 - plant and equipment: Depreciation on fixtures and fittings (carpet, appliances, blinds, hot water system, air conditioning) over their effective life. New properties have significant Division 40 deductions in early years
- 2017 restriction on second-hand plant: From 9 May 2017, plant and equipment in a second-hand residential property CANNOT be depreciated by subsequent buyers (only the original owner and purchasers of new property can claim Division 40). Division 43 building works are unaffected - still claimable on all qualifying buildings regardless of when purchased
- New vs established property depreciation difference: A new property built in 2023 may generate $15,000-$20,000 in total first-year depreciation. An established 1990s property bought second-hand may generate only $3,000-$5,000 (Division 43 only). This difference significantly affects after-tax cash flow comparisons between new and established property investment
Is Negative Gearing Right for You? A Decision Framework
Negative gearing is not universally beneficial - it suits specific financial circumstances and requires a long-term commitment. This framework helps evaluate suitability.
- Income requirement: Negative gearing only generates a tax benefit if you have assessable income against which to offset the loss. If you earn under the tax-free threshold, negative gearing produces no tax saving - the loss accumulates and cannot be used until you earn taxable income
- Marginal rate sensitivity: The higher your marginal rate, the larger the tax refund per dollar of loss. At 37% you get 37 cents back per dollar lost. At 32.5% - 32.5 cents. At 19% - 19 cents. High-income earners benefit most
- Long-term commitment: Negative gearing properties typically require 7-15 year holding periods for capital growth to meaningfully exceed accumulated cash outflows. Short-term holders crystallise losses without realising the capital gain upside
- Cash flow sustainability: Can you fund $151/week (in our example) indefinitely - including through interest rate rises, vacancy periods, and major repairs? A rental property should be tested against a 2% interest rate rise scenario to ensure serviceability
- Alternative strategies: At marginal rates of 37%+, salary sacrifice to super saves 22 cents per dollar with zero capital risk. For the same tax saving, super contributions are lower risk than a leveraged property investment - but without the leverage upside
- Location selection overrides tax strategy: Buying the 'wrong' property in the 'right' tax structure is worse than the 'right' property in the 'wrong' structure. Location, rental demand, and growth drivers must be evaluated independently of the tax position - negative gearing is a tax outcome of the investment, not a reason to invest
