Rentvesting Tax in Australia 2026-27: The Rules That Actually Apply to You

Rent where you want to live, buy where you can afford. That’s rentvesting in one line. The tax side is messier than most guides admit — two of the biggest breaks investors talk about, the 6-year rule and the 50% CGT discount, may barely help you at all in 2026-27:

• Your investment property gets no main residence exemption — you’ll pay CGT when you sell, even if you never lived in it.
• The 6-year rule only helps if you lived in the property first. Never lived in it? It doesn’t exist for you.
• The 50% CGT discount is on its way out. Under the 2026-27 Budget reforms, from 1 July 2027 cost-base indexation plus a 30% minimum tax replaces it — and established properties bought after 12 May 2026 never get the discount at all.
• While you hold the property you can claim interest, rates, insurance, agent fees, repairs and depreciation — but negative gearing changed too: for established properties bought after 12 May 2026, rental losses can no longer be offset against your salary.
• Land tax applies to the investment property (your own home is exempt), with thresholds that differ wildly by state.

How rentvesting works, tax-wise

For tax purposes, rentvesting splits your life into two halves. The property you rent to live in? The ATO doesn’t care about it — the rent comes out of after-tax pay and isn’t deductible. The property you own and rent out? That’s a full investment asset, taxed like one.

On the income side, every dollar of rent is assessable income, taxed at your marginal rate — for 2026-27 that’s 15% from $18,201, 30% from $45,001, 37% from $135,001 and 45% from $190,001, plus the 2% Medicare levy.

On the deductions side, just about every cost of earning that rent is claimable: mortgage interest, council and water rates, landlord insurance, property management fees, repairs, pest control, body corporate fees, land tax, and accounting fees. This is the one genuine tax advantage over owner-occupying — an owner-occupier can’t deduct a cent of their mortgage interest, while you can deduct all of yours.

That’s the trade: deductions while you hold it, CGT when you sell it.

The 6-year-rule trap: most rentvestors can’t use it

If you’ve spent time on property forums, you’ve seen the 6-year rule invoked like a magic spell. Section 118-145 of the tax law really does let you move out, rent your former home for up to six years, and sell it tax-free — but it has a starting condition that disqualifies the typical rentvestor completely.

The property must have been your main residence first. The ATO looks at the facts: where you actually lived, where your belongings were, your electoral roll address. Buy and rent it out from day one — the standard rentvesting pattern — and the 6-year rule never switches on. There is no main residence to be “absent” from.

• Lived in it first, then rented it: treat it as your main residence for up to 6 years of income-producing use; sell inside that window (no other main residence claimed) and the gain can be fully exempt.
• Left it vacant: no 6-year cap — the exemption can run indefinitely.
• Never lived in it: none of this applies. Full stop.

This is also why the common forum advice — “just move into your investment property before you sell and it’s your main residence, so no CGT” — is wrong. Moving in late doesn’t backdate the exemption. The gain gets apportioned: years as an investment are taxable, years as your home are exempt. Own for 10 years, rent for 7, live in it for 3 — roughly 70% of the gain is still taxable.

There is one related rule worth knowing for later: if you eventually buy a home to live in, the moving-between-homes overlap lets you treat both properties as your main residence for up to six months while you sell the old one. Otherwise you can only treat one property as your main residence at a time.

Worked CGT example: what selling actually costs in 2026-27

This is where the 2026-27 Budget rewrites the playbook. Legislation (Royal Assent June 2026) replaced the 50% CGT discount with cost-base indexation plus a 30% minimum tax on net capital gains, applying to gains arising from 1 July 2027. The detail that matters for rentvestors: established properties bought after 12 May 2026 (contract date) never get the 50% discount on any portion of future gains.

Here’s what that looks like with realistic numbers. Say you rentvest in October 2026:

The numbers: established unit in Melbourne, contract October 2026. Purchase $620,000 plus stamp duty, legal fees and buyer’s agent — all-in cost base ~$660,000. Rented continuously for 8 years; you never live in it. Sold 2034 for $900,000, less ~$18,000 selling costs → nominal gain ~$222,000. Under the new regime: no 50% discount (contract after 12 May 2026). The $660,000 cost base is indexed for inflation — illustratively, ~2.5% a year for 8 years lifts it to about $805,000. Taxable “real” gain ≈ $77,000, and the 30% minimum tax means at least ~$23,000 in CGT (the 30% is a floor, not a flat rate). Under the old 50%-discount world the same gain would have been halved to $111,000 and taxed at your marginal rate — ~$33,300 for a 30% taxpayer. So in moderate-inflation scenarios the new system can be gentler for middle-income investors, but it bites harder when inflation is low, and the 30% floor hurts anyone whose marginal rate would otherwise sit below 30%.

Contrast — the old rules: gains realised before 1 July 2027 still get the 50% discount. And if you bought before 12 May 2026 but sell after 1 July 2027, transitional rules split the gain: 50% discount on the portion accrued to 30 June 2027, indexation plus minimum tax on the rest (the property’s 1 July 2027 value becomes the new cost base — yes, that may mean a valuation).

Two carve-outs soften the blow for some rentvestors: investors in new residential property can choose on disposal between the old 50% discount and the new indexation-plus-minimum-tax regime — and the main residence exemption is unchanged. Our full CGT reform guide covers the transitional rules in detail.

Rental income, deductions and the new negative gearing reality

While you hold the property, the annual tax picture is straightforward — with one big 2026-27 change hiding in it:

• Rent: $520/week → $27,040 a year, all assessable income
• Mortgage interest: $30,000
• Rates, insurance, management fees, repairs: $8,000
• Depreciation (see below): $9,000
• Net rental loss: ~$20,000

Before the Budget changes, that $20,000 loss would simply reduce your salary — at a 30% marginal rate plus 2% Medicare levy, worth about $6,400 back. That was negative gearing, the engine room of rentvesting cashflow. Now, for established residential properties bought after 7:30pm AEST on 12 May 2026, net rental losses can no longer offset salary — they’re quarantined and carried forward against future rental profits or the eventual capital gain. New builds are excluded.

One more thing people get backwards: the rent you pay on your own home is never deductible. Only the investment side of your life generates deductions.

Depreciation: the deduction rentvestors actually under-claim

Depreciation is the deduction you get without spending a dollar that year, and it’s where a lot of rentvestors leave money on the table. Two separate divisions apply:

Division 43 — capital works (the building itself). For residential buildings constructed after 15 September 1987, claim 2.5% of the construction cost each year for up to 40 years — a $400,000 build means up to $10,000 a year. It applies even to second-hand purchases; the remaining depreciable life comes with the building.

Division 40 — plant and equipment (the removable stuff). Air conditioners, carpets, blinds, hot water systems, ovens. The trap: since the 2017 Budget changes, buyers of established property can’t claim depreciation on second-hand plant and equipment already in it. You can still claim brand-new items you install after settlement — and everything if you buy new.

Practical takeaway: get a depreciation schedule from a quantity surveyor after settlement — it usually pays for itself many times over.

Land tax: the bill owner-occupiers never see

Your own home is exempt from land tax in every state. Your investment property isn’t — and as a rentvestor it’s the only property you own, so no PPR exemption shields you. For 2026:

• NSW: $1,075,000 (frozen since the 2025 land tax year) — $100 plus 1.6% above; premium 2% above $6,571,000.
• Victoria: just $50,000 — including the temporary COVID debt levy to 30 June 2033.
• Queensland: $600,000 for individuals; WA: $300,000; SA: $936,000.

The Victorian threshold is the one that ambushes rentvestors: a $700,000 Melbourne unit with a $250,000 land value attracts land tax from year one — an annual cost an owner-occupier of the identical property never faces. It’s deductible against rental income, but still cash out the door. See our land tax by state guide.

What if you move into the investment property later?

Plans change. Many rentvestors eventually move into their investment property — and the tax treatment changes with you, but not the way forums suggest. Moving in stops the deductions from that day, and it stops future CGT from accruing — but the gain built up while it was rented stays taxable, apportioned by time. Ten years owned, seven as a rental, three as your home: roughly 70% of the gain remains taxable. A token two-week move-in before settlement doesn’t change the maths, and anti-avoidance rules target arrangements set up purely to dodge the tax.

One main residence at a time. If you buy a separate home while still holding the rented-out investment, you must choose which property gets the main residence exemption for the overlap — you can’t exempt both. The exception is the six-month overlap when genuinely moving from one home to another while selling the old one.

Common mistakes rentvestors make

1. Assuming the 6-year rule covers them. It doesn’t, unless you lived in the property first. This is the single most expensive misunderstanding in rentvesting.
2. Believing a last-minute move-in wipes out CGT. The gain is apportioned — late residency exempts a late slice, nothing more.
3. Counting on negative gearing against salary. For established properties bought after 12 May 2026, rental losses are quarantined and carried forward — they don’t reduce this year’s salary.
4. Forgetting land tax in Victoria. A $50,000 threshold catches almost every Melbourne investment. Budget for it from year one.
5. Trashing the paperwork. Keep the settlement statement, improvement invoices and loan records — they build your cost base and shrink your eventual CGT. Keep records for at least five years after you sell.
6. Claiming improvements as repairs. A renovation isn’t a repair — it generally goes into the cost base (reducing CGT later) or Division 43, not into this year’s deductions.

Tips to get the tax side right

• Price the reform into your buy decision. New builds now carry a genuine tax edge: the choice of 50% discount or indexation on sale, full depreciation on everything, and no negative-gearing quarantine. Weigh that against the developer price premium.
• Get the depreciation schedule early. A quantity surveyor’s report after settlement captures Division 43 and any new Division 40 items — don’t guess construction costs yourself.
• Keep a cost-base file from day one. Stamp duty, legal fees, buyer’s agent fees, improvements, selling costs — every dollar documented is a dollar off your eventual capital gain.
• Don’t burn first home buyer benefits blindly. Buying investment-first forfeits stamp duty concessions, cash grants and the federal 5% Deposit Scheme on this purchase — and in most states you stop being a “first home buyer” the moment you own anything. Some states still let you claim concessions later on a home you buy to live in, provided you never lived in the investment — check your state’s rules first.
• Talk to an accountant before you sell, not after. The CGT event happens on the contract date, and the transitional valuation questions for the 1 July 2027 changeover are genuinely tricky.

Frequently asked questions

Can I claim the main residence exemption on a property I never lived in?

No. The main residence exemption — and the 6-year absence rule that extends it — only applies to a property that was genuinely your home first. A rentvestor who buys and immediately rents out the property has no main residence exemption to claim, ever, on that property.

Does the 6-year rule help rentvestors?

Only the unusual ones who lived in the property first, then moved out and rented elsewhere. Never lived in it? The rule can’t apply. Lived in it first? You can rent it up to 6 years and still sell CGT-free, provided you don’t claim another main residence in between.

Does the 50% CGT discount still apply if I buy in 2026-27?

It depends on the contract date. For established property bought after 12 May 2026, the 50% discount is gone for gains arising from 1 July 2027 — indexation of your cost base plus a 30% minimum tax applies instead. Gains realised before 1 July 2027 still get the discount, and new builds keep a choice of either treatment. See the ATO’s guidance on treating a former home as your main residence and our CGT reform guide for detail.

If I move into my investment property before selling, is the sale CGT-free?

No — the gain is apportioned. Only the period it was your main residence is exempt; the years it was rented remain taxable. Moving in stops future CGT from accruing but doesn’t erase the past.

Can I still negatively gear my rentvesting property against my salary?

For established residential properties bought after 7:30pm AEST on 12 May 2026, no — net rental losses can no longer offset salary or other non-rental income. They’re carried forward against future rental profits or the eventual capital gain. New builds are excluded, and pre-cutoff purchases keep the old treatment.

Do I pay land tax as a rentvestor?

Yes, if the land value exceeds your state’s threshold — and unlike owner-occupiers, you have no principal-residence exemption. In Victoria the $50,000 threshold means most investments attract land tax from year one; in NSW the $1,075,000 threshold means many single-property investors pay nothing. It’s deductible against rental income either way.

Rentvesting can still work — deductible debt, depreciation, and a foot on the property ladder while living where you want. But in 2026-27 the tax maths has shifted: no 6-year rule without prior residency, no 50% discount on post-May-2026 established purchases, and quarantined rental losses. Go in with the real numbers, and the strategy stays honest.
