Negative Gearing Explained: What It Is and What It Means for Your Rent

Negative gearing has been all over the news since the federal budget. Your landlord may have already mentioned it. But what does it actually mean, and does it change anything about the rent increase notice on your kitchen table? Here is the plain-English version, and what it means for you specifically.

What negative gearing actually is

Start with the basics. When a landlord's costs are higher than the rent they collect, they are making a loss on the property. Those costs include mortgage interest, insurance, council rates, property management fees, and maintenance. If the rent coming in is less than all of that going out, the property is "negatively geared."

Here is the part that matters: Australian tax law lets landlords deduct that loss against their other income, typically their wages. This reduces their taxable income, which reduces their tax bill. The Australian Tax Office effectively covers part of the loss through that tax saving.

That tax saving is the whole point. The landlord is betting that the property will grow in value over time (capital growth), and in the meantime the government is subsidising their loss through the tax system.

A real example with actual numbers

Here is how it works in practice.

Example only. Individual tax outcomes depend on the landlord's full financial position.

In this scenario, the landlord loses $6,800 a year on the property but gets back $2,516 through the tax saving. Their net out-of-pocket loss is around $4,300. They are betting that the property grows in value by more than that each year, and when they eventually sell, they pocket the capital gain. That has been a reliable bet in Australian property for decades.

Why it matters for renters

Negative gearing shapes who buys Australian property and why. Here is the honest version of the debate.

The case that it pushes up rents

Because the tax system subsidises losses, investors can afford to hold properties that do not stack up on rental income alone. That pulls more buyers into the market, pushing up purchase prices, which means fewer Australians can afford to buy their own home and more people stay in the rental market for longer. More renters competing for the same rental stock pushes rents up.

The counter-argument

Investors also provide rental supply. Without the tax incentive, some argue, fewer investors would enter the market, rental stock would shrink, and rents would rise further. The government's own modelling on the 2026 budget changes (which restricted negative gearing for new purchases of existing properties) projected a $2/week national rent increase, suggesting they expect the impact on rents to be modest.

What is clear

The tax benefit makes it viable for investors to hold properties at a loss in the hope of capital growth. That is the engine driving a large share of Australian property investment. Whether it helps or hurts renters on balance depends on who you ask. What does not depend on who you ask: your specific rent increase negotiation.

What the 2026 budget changed

The May 13 budget restricted negative gearing against general income (wages and other income) to new build properties only, for investment properties purchased after budget night. Investors who buy existing homes after May 13, 2026 can still deduct losses against residential property income and carry losses forward, but not against wages.

The critical detail: every investment property purchased before May 13, 2026 is fully exempt. Existing landlords continue under the old rules. The changes are not retroactive.

For the full breakdown of what changed, who is affected, and what the government's $2/week rent projection actually means, see what the 2026 budget changed for renters.

What this means if you have a rent increase today

Here is the practical answer: it does not change your negotiation.

Whether your landlord is negatively geared, positively geared, or somewhere in between, the strongest argument in a rent negotiation is not about their tax position. It is about their replacement cost: what it would cost them to find a new tenant if you leave.

• Two weeks of vacancy on a $600/week property: $1,200
• Reletting fee (1 to 2 weeks rent): $600 to $1,200
• Advertising on Domain and REA: $200 to $400
• Repairs and cleaning between tenancies: $300 to $800

Total: $2,300 to $3,600 conservatively. More for higher-rent properties or longer vacancies. A landlord losing $4,300 a year on a negatively geared property is still better off keeping a reliable tenant at a slightly lower rent than paying $3,000 to find a new one.

That is your leverage. It does not change based on gearing status, tax law, or what the budget said.

What to do if your landlord cites negative gearing

Do not engage with the tax argument. You cannot win a debate about someone else's finances, and tribunals do not assess rent increases based on a landlord's tax position anyway. The test is always market rent for comparable properties.

Instead, redirect to the replacement cost. A counter-offer built around what it costs to replace you is concrete, commercially reasonable, and harder to dismiss than a policy debate.

1. Run the replacement cost calculation. Find the break-even rent: the point at which your landlord nets the same whether they replace you or keep you at a lower rent.
2. Counter-offer with a specific number. "Based on your replacement cost, I'd like to counter-offer $X/week" is a complete opening. See the full negotiation guide for how to frame it.
3. Check whether the increase is reasonable. Is my rent increase reasonable? walks through the two benchmarks to run before you respond.

The bottom line

Negative gearing is a tax strategy. It shapes who invests in Australian property and why, and it has been part of the policy debate for decades. Whether it helps or hurts renters on balance is a genuine argument economists have not settled.

What it is not: a reason to accept a specific rent increase. Your landlord's tax arrangements are their business. Your negotiation is built on one number: what it costs them to replace you. That number is knowable, and it is almost always lower than what they asked for.
