What is Negative Gearing for Property Investors?

Negative gearing happens when the costs of owning a rental property exceed the rental income it generates, creating a loss you can claim against other income to reduce your tax.

If you're thinking about purchasing an investment property in North Plympton, understanding negative gearing is important because major changes to the tax rules came into effect in mid-2026. These changes reshape how rental losses are treated, depending on when you buy and what type of property you choose. For migrants building wealth through property, knowing which purchases still qualify for negative gearing under the old rules, and which fall under the new quarantine arrangements, affects both your cash flow and your long-term strategy.

How Negative Gearing Works Under the Current Rules

Negative gearing allows you to deduct the shortfall between your rental income and your property expenses, including interest on your investment loan, against your salary or other income.

Consider an investor who purchases a two-bedroom villa unit in North Plympton at the current median. They borrow at a variable interest rate with a 20 per cent deposit. Annual interest might run around $18,000, while rental income at typical North Plympton yields brings in roughly $16,000. Add another $3,000 in council rates, strata fees, insurance, and repairs, and the total annual cost reaches $21,000. The investor has a $5,000 rental loss. Under the rules that applied until mid-2026, that $5,000 loss reduces the investor's taxable income. If they earn a salary that puts them in the 37 per cent marginal tax bracket, the deduction saves them around $1,850 in tax, bringing their actual out-of-pocket cost to $3,150 for the year.

That shortfall is what makes it "negative". You are gearing, or borrowing, to invest, and the result is negative cash flow. The tax deduction softens the impact.

What Changed in Mid-2026

From 7:30pm AEST on 12 May 2026, a new rule applies to most residential investment properties.

If you purchase a property on or after that date and time, rental losses can only be offset against other residential rental income or carried forward to reduce future rental income or capital gains from residential property. You cannot offset the loss against your salary, business income, or dividends. Properties you already owned at that date and time, or those under contract awaiting settlement, remain under the old rules and can still be negatively geared in the traditional sense until you sell them.

There is a transitional window. Properties purchased between 7:30pm on 12 May 2026 and 30 June 2027 could still use negative gearing under the old rules until 30 June 2027. From 1 July 2027, those properties fall under the quarantine rules.

Eligible New Builds Are Exempt from the Quarantine

Properties classified as eligible new residential dwellings remain eligible for negative gearing under the traditional rules, regardless of when you buy them.

An eligible new build is a dwelling constructed on previously vacant land, or a property where the number of dwellings increased after development. A knock-down rebuild that replaces one dwelling with one dwelling does not qualify. Neither does a substantial renovation of an existing property. If a new build is occupied for more than 12 months before being sold to you as an investor, it also loses eligibility.

North Plympton has seen some medium-density townhouse developments along Anzac Highway and near the train station precinct. If you purchase a newly completed townhouse in one of those developments before it has been lived in for 12 months, it would qualify as an eligible new build. That means you can still claim rental losses against your wage income, just as investors could before the rule change.

The policy is designed to encourage supply. Properties that increase the number of available dwellings attract the tax treatment, while established properties do not.

How Lenders Assess Investment Loan Applications Now

Lenders assess investment loan applications based on rental income, your other income, and your existing debts, with a serviceability buffer applied to the loan's interest rate.

From February 2026, debt-to-income caps also apply. A lender may approve up to 20 per cent of their new investor loans at a debt-to-income ratio of six times or greater. If your total debt, including the new loan, exceeds six times your gross income, you may still be approved, but the lender will manage that portion of their portfolio carefully. If you are close to that threshold, a lower loan amount or a larger deposit may be needed.

Lenders also assess rental income differently depending on whether the property is tenanted at application. If the property is already leased, they will use the actual rent, sometimes shaded by a percentage to allow for vacancy. If the property is not yet tenanted, they will use a valuer's estimated rental yield or apply a standard percentage of the property's value. The rental income is added to your other income, and the loan repayment, calculated on principal and interest even if you choose interest-only, is compared against your total income with the buffer applied.

The negative gearing quarantine does not change how lenders assess your application. They still use rental income in their calculations. The quarantine affects your tax return, not the lender's serviceability model.

Interest-Only Loans and Rental Property Cash Flow

Interest-only repayments reduce your monthly outgoings and increase the size of the rental loss you can claim.

Many property investors choose an interest-only period, typically up to five years, to keep cash flow manageable while building equity through capital growth rather than principal repayment. On a loan amount of $400,000 at a variable interest rate, the interest-only repayment might be around $1,850 per month, while a principal and interest repayment on the same loan could be closer to $2,400. That difference is $550 per month, or $6,600 per year.

If you are negatively geared under the old rules, the larger loss from interest-only repayments increases your tax deduction. If you are subject to the quarantine, the larger loss can still be carried forward and used against future rental income or capital gains, but it does not reduce your current-year tax unless you have other residential rental income to offset it against.

Interest-only repayments do not reduce the loan balance. At the end of the interest-only period, the loan reverts to principal and interest, and the repayment increases. You can often extend the interest-only period or refinance to a new loan with a fresh interest-only term, but lenders will reassess your serviceability at that time.

Claimable Expenses Beyond Interest

You can claim a range of property expenses, not just loan interest.

Council rates, water and sewerage charges, strata fees, landlord insurance, property management fees, repairs and maintenance, and depreciation on the building and fixtures are all deductible. In a suburb like North Plympton, where older-style villas and updated units sit side by side, depreciation schedules vary. A recently renovated property with new appliances, flooring, and window coverings will deliver larger depreciation deductions than an unrenovated 1960s villa.

Stamp duty on the property purchase is not immediately deductible. It forms part of the property's cost base and reduces your capital gain when you eventually sell. Borrowing costs, such as loan establishment fees and lender's mortgage insurance, can be claimed over five years or the life of the loan, whichever is shorter.

If your property is subject to the quarantine, all these deductions still apply. They contribute to the rental loss, which you carry forward and use later.

What This Means for Portfolio Growth and Refinancing

Carrying forward quarantined losses rather than claiming them immediately changes your after-tax cash flow, but it does not stop you expanding your portfolio.

If you own one negatively geared property under the new quarantine rules and you purchase a second investment property, any rental income from the second property can be offset by the losses from the first. Once you have more than one rental property, the quarantine becomes a pool. Income and losses net off across your entire residential rental portfolio.

That structure can support portfolio growth. A positively geared property, generating more income than expenses, can absorb losses from a negatively geared property in the same tax year. Some investors now consider a mix of high-yield regional properties and lower-yield metro properties to manage the quarantine.

Refinancing an existing investment loan does not change the tax treatment of the property. If the property was purchased before 7:30pm on 12 May 2026, it remains under the old rules regardless of how many times you refinance. If it was purchased after that time and is subject to the quarantine, refinancing does not alter that. However, refinancing to access equity for a deposit on another property does create new borrowing, and the deductibility of interest on that new borrowing depends on what the funds are used for. If the equity is used to purchase another investment property, the interest on that portion is deductible. If it is used for private purposes, it is not.

Capital Gains Tax and the 2027 Changes

From 1 July 2027, a separate change affects how capital gains on investment properties are taxed.

The 50 per cent capital gains tax discount for individuals is being replaced with cost base indexation and a minimum 30 per cent tax rate on real gains, but only for gains that accrue after 1 July 2027. Gains that built up before that date remain under the current discount rules. Eligible new builds offer an election between the 50 per cent discount and the new indexed treatment, giving investors flexibility depending on their circumstances.

If you purchase an established investment property in North Plympton now and sell it in ten years, part of the gain will be calculated under the old discount and part under the new indexed system. The split depends on how much of the gain accrued before and after 1 July 2027. The quarantined rental losses you carried forward can be offset against the taxable capital gain when you sell, reducing the tax payable at that time.

For migrants planning long-term wealth building, understanding how carried-forward losses interact with future capital gains is part of the total return calculation.

Selecting the Right Investment Loan Features

The loan structure you choose affects how much flexibility you have as rental income, interest rates, and tax rules change.

A loan with an offset account lets you park savings and reduce interest charges without losing access to the cash, but be aware that reducing the interest you pay also reduces your deductible expense. If you are negatively geared under the old rules, a smaller interest bill means a smaller tax deduction. Some investors prefer a redraw facility for that reason, drawing down only when needed and maximising deductible interest in the meantime.

Splitting your loan between fixed and variable portions gives you partial rate protection while retaining flexibility to make extra repayments on the variable portion. Fixed rates also lock in your deductible interest expense, which can help with tax planning if you know your marginal rate will stay high for the next few years.

Access to a range of investment loan options from banks and lenders across Australia means you can match loan features to your tax position, your cash flow, and your plans for the property. Some lenders offer better rates for interest-only loans, others for principal and interest. Some charge lower fees, others offer faster preapproval for portfolio investors.
