Is Negative Gearing Worth It? Weighing the Pros and Cons

You’re staring at a rental property with a shortfall between rent and repayments, and your accountant or a mate at a barbecue has mentioned the tax deduction that comes with it. That’s the pitch behind negative gearing, and is negative gearing worth it depends entirely on your income, your cash flow tolerance, and how long you plan to hold the asset. It’s not a strategy that suits every investor, despite how often it gets recommended as one.

The honest answer is that negative gearing only pays off when capital growth outweighs the ongoing losses you’re funding out of your own pocket. It reduces your taxable income today, but you’re still writing a cheque to cover the gap between rent and expenses, and that only makes sense if the property’s value climbs enough to justify the wait.

In this article, we’ll walk through how negative gearing actually works, when it stacks up financially, and where it can quietly erode your wealth building goals instead of supporting them. We’ll also cover the questions worth raising with your accountant before you commit, drawing on what we see play out with property investors here in Melbourne.

Why negative gearing matters for property investors

Property investors chase negative gearing because it directly cuts your tax bill while you build equity in an asset. When your rental expenses exceed your rental income, the Australian Taxation Office lets you offset that loss against your salary or other income, which lowers what you owe come tax time. This is why so many Melbourne investors get talked into it early: the deduction feels immediate and tangible, even though the property itself might not turn a profit for years. The Australian Taxation Office sets out exactly which expenses qualify, from loan interest to depreciation, and it’s worth reading their official guidance on rental property deductions before you assume every cost is claimable.

Why growth timing decides the outcome

Understanding the mechanics is one thing, but the real question is whether the strategy earns its keep over time. Negative gearing only makes sense when the property’s capital growth eventually outpaces the losses you’re funding out of pocket each year. If prices stall or drop, you’re left holding a property that costs you money monthly and hasn’t delivered the payoff that justified the pain.

Negative gearing isn’t a tax strategy, it’s a bet on growth that happens to come with a tax offset attached.

Victorian and interstate markets don’t move in lockstep, so the same negative gearing setup that pays off in a high-growth Brisbane suburb can drag on for a decade in a flat regional market. That’s why timing your entry, understanding local supply and demand, and having a realistic exit horizon matter more than the deduction itself.

The cash flow reality most investors underestimate

Running the numbers matters because a shortfall you can absorb at a 5% interest rate might become unmanageable if rates climb another percentage point. Consider how the maths shifts:

Spotting that gap before you sign a loan is far cheaper than discovering it after settlement. Owners who stress-test their cash flow against rate rises, vacancy periods, and unexpected repairs go in with realistic expectations, while those who only look at the tax refund often get caught short within the first two years.

How to work out if negative gearing suits you

Working out whether negative gearing suits you starts with an honest look at your marginal tax rate, not the property listing. The higher your income, the more valuable the deduction becomes, because you’re offsetting losses against tax paid at 37% or 45%, rather than 19% or 32.5%. If you’re on a lower income, the same deduction is worth far less, which changes the whole equation before you even look at a suburb.

Check your marginal tax rate first

Ask yourself what bracket you sit in and how long you expect to stay there, since a temporary pay rise or a career change can shift the maths within a year or two. Investors on high, stable incomes tend to get the most out of negative gearing, while those expecting income to drop, retire, or take parental leave often find the deduction shrinks just when they need cash flow support most.

If the tax saving is the main reason you’re buying the property, you’re solving the wrong problem.

Test your cash flow tolerance

Beyond tax brackets, you need to know how much monthly shortfall you can genuinely absorb without stress, because cash flow pressure is what forces investors to sell at the wrong time. Run through this before you commit:

• Can you cover a $500 to $1,000 monthly shortfall for at least three years without touching savings?
• Have you modelled a two-percentage-point rate rise against your loan?
• Does your household have six months of expenses set aside separately from the property?
• Have you factored in vacancy periods of four to eight weeks?

Getting straight answers to these questions tells you more about whether negative gearing suits you than any tax refund estimate ever will.

Weighing the pros and cons of negative gearing

Balancing the ledger on negative gearing means looking past the tax refund and asking what you’re actually trading for it. Tax relief today comes at the cost of ongoing cash flow pressure, and that trade-off suits some investors far better than others.

What negative gearing gets right

Supporters point to the immediate reduction in taxable income, the ability to enter a growth market sooner than saving a full deposit would allow, and the long-term capital growth potential if you pick the right suburb. Depreciation schedules add another layer of deduction on newer properties, stacking the benefit further for investors with the income to use it.

Where the strategy falls short

Critics rightly flag that you’re funding a loss every month, hoping the market repays you years later, and that hope isn’t a financial plan. Rate rises, vacancy periods, and unexpected repairs can turn a manageable shortfall into a genuine strain, particularly for investors who stretched their borrowing capacity to get into the market.

The tax deduction is real, but it’s a consolation prize, not the reason to buy.

Reading that table honestly, rather than picking the column that flatters your decision, is what separates investors who use negative gearing well from those who get burned by it. Weighing both sides against your own income and risk tolerance, not a generic rule of thumb, is the only way to know if it’s genuinely worth it for you.

How the 2027 rule changes could affect your strategy

Debate about tightening negative gearing rules has resurfaced in Canberra more than once, and each time it does, investors ask whether their current setup will survive the next parliamentary term. No legislation locks in a 2027 change at the time of writing, but Treasury has previously modelled options at the government’s request, and past proposals from minor parties have floated capping the deduction to one property or grandfathering existing investments while applying stricter rules to new purchases from a future date. Nothing here is confirmed law, so treat any specific timeline with caution and check the Treasury website directly before acting on rumour.

What’s actually on the table

Proposals that have circulated in policy discussions generally fall into a few camps:

• Limiting negative gearing to one investment property per taxpayer
• Grandfathering existing arrangements while applying new rules only to future purchases
• Combining changes to the capital gains tax discount alongside any negative gearing reform
• Phasing in restrictions gradually rather than as a single cutover date

Each option would hit differently depending on how many properties you hold and when you bought them, which is why blanket predictions rarely hold up.

Why you should plan for policy risk anyway

Regardless of which version eventually gets legislated, the sensible move is building a strategy that doesn’t collapse the moment the rules shift. Structuring your portfolio so it can still service debt without the deduction, and keeping loan-to-value ratios conservative, protects you whichever way Canberra lands.

Build your numbers to survive without the tax deduction, then treat any benefit from it as a bonus, not a foundation.

Gartly Advisory keeps a close eye on these proposals for clients precisely because a strategy built on today’s tax rules alone is fragile if those rules move.

Negative gearing vs positive gearing: which fits you

Comparing negative gearing with positive gearing comes down to what you need your property to do for you right now. Positive gearing means your rental income covers all expenses and leaves you with surplus cash, which gets taxed as ordinary income. Negative gearing flips that, generating a loss you claim against your other earnings while you wait for the property to grow in value. Neither approach is universally better, and the right fit depends on your income, your appetite for risk, and how soon you need the investment to pay for itself.

Comparing the two approaches

Laying the numbers side by side makes the trade-offs obvious:

Positive gearing pays you today, negative gearing bets on tomorrow, and your income and patience decide which bet makes sense.

Matching the strategy to your goals

Retirees and investors nearing retirement generally lean towards positive gearing, since the last thing you want in your sixties is a monthly shortfall eating into your pension or savings. Younger investors on high, stable salaries often tolerate negative gearing better, because the tax offset works harder for them and they’ve got decades ahead for growth to catch up. Speak to your accountant about blending both across a portfolio, since holding one negatively geared asset alongside a positively geared one can balance your cash flow while still chasing growth where it counts.

Deciding what’s right for your situation

So, is negative gearing worth it? Only if the numbers work for your specific income, cash flow buffer, and time horizon, not because it worked for a colleague or a property spruiker’s slideshow. The tax deduction is genuine, but it’s a by-product of a growth bet, not a substitute for one. Run your own figures, stress-test them against rate rises, and be honest about how long you can fund a shortfall before the property needs to start paying its own way.

Getting this wrong is expensive, and getting it right takes more than a rule of thumb. If you want someone to pressure-test your numbers against your actual tax position and risk appetite, rather than a generic calculator, talk to the team at Gartly Advisory before you sign anything.
