Budget's Nasty CGT Surprise for Australians Doing a Stint Overseas: Property Tax Trap and Loan Strategy

The 2026 Budget’s CGT Trap: What Actually Changed?

The Australian Tax Office (ATO) has long allowed homeowners to claim the main residence exemption from CGT when selling their home, even if they lived overseas temporarily. But the 2026 Budget, announced on July 11, tightens this significantly. From July 1, 2026, the exemption will only apply if you were an Australian resident for tax purposes for the entire period you owned the property—or for at least six years out of the last ten before sale.

For Australians doing a stint overseas—say, a two-to-five-year work assignment—this is a game-changer. Previously, you could sell after returning and still claim the full exemption, provided the property was your main residence at some point. Now, if you’re a non-resident when you sell, the exemption is capped. Worse, the Budget also reduces the "absence concession" from six years to four years for properties you rented out while away. That means if you rent your home for more than four years while overseas, you lose the exemption entirely.

Real-world example: Let’s say you bought a home in Sydney for $800,000 in 2020. You move to New York in 2023 for a three-year contract, renting out your home. In 2026, you sell for $1.1 million. Under the old rules, you’d pay no CGT. Under the new rules, because you were a non-resident for part of the ownership period and rented it for three years (under the four-year limit), you might still qualify for a partial exemption—but only if you sell before the four-year rental cap. If your stint extends to five years, you lose the exemption entirely, and you’d owe CGT on the full $300,000 gain at the non-resident rate (currently 12.5% for foreign residents, but could be higher depending on your situation).

The key takeaway: timing matters. If you’re planning a temporary overseas move, the Budget forces you to think about your exit strategy earlier than before.

How This Affects Your Mortgage Strategy: Compare Your Loan Options

Now, here’s where ozLoan comes in. A CGT bill isn’t just a tax problem—it’s a cash flow problem. If you’re forced to sell your home to avoid a tax hit, or if you decide to hold it longer, your mortgage choice becomes critical.

First, consider the type of loan you have. If you’re renting out your home while overseas, you’ll likely need an investment property loan, not a standard owner-occupier loan. Many lenders require you to switch to an investor loan if the property is no longer your primary residence, or they may charge higher rates. Compare interest rates for investor loans on ozLoan’s compare page—rates can vary by up to 1.5% between lenders, which on a $600,000 loan means a difference of $9,000 per year.

Second, think about loan features. If you plan to sell within four years to avoid the CGT trap, a fixed-rate loan with a short term (two to three years) might be ideal. But if you’re holding long-term, a variable rate with offset account could save you tax on rental income. For example, if you earn $30,000 in rent annually and have a $500,000 loan with an offset account, you could reduce your taxable interest by parking savings there. Compare offset accounts on our guides page to see which lenders offer the best terms.

Third, don’t forget about borrowing power. As a non-resident, your borrowing capacity drops sharply—most lenders cap loans at 60-70% of property value for expats, versus 80% for residents. If you’re planning to buy another property overseas or refinance, this can be a shock. Use ozLoan’s comparison tools to find lenders that specialise in expat mortgages, like those offering "non-resident" loans with lower LVR requirements.

Case Study: Comparing Two Scenarios for an Australian Working in Dubai

Let’s make this concrete. Meet Sarah, a 35-year-old engineer who bought a Melbourne apartment for $650,000 in 2021. In 2024, she gets a four-year contract in Dubai. She has two options:

Scenario A: Sell before moving. Sarah sells her apartment in 2024 for $750,000, making a $100,000 gain. Because she’s still an Australian resident, she pays no CGT under the main residence exemption. She uses the proceeds to pay off her mortgage and invests the rest. No tax headache.

Scenario B: Rent and sell after four years. Sarah keeps the apartment, rents it out for $25,000 per year, and sells in 2028 for $800,000. Under the new rules, because she rented it for exactly four years (the new limit), she might still qualify for a partial exemption—but only if she returns to Australia before the sale. If she extends her stay by even six months, she loses the exemption entirely. In that case, she owes CGT on the $150,000 gain at the non-resident rate (say 12.5% = $18,750). Plus, she’s paid mortgage interest and property management fees for four years, reducing her net profit.

Which is better? It depends on her mortgage. In Scenario B, if she has a low-rate investor loan (say 5.5% vs 6.5% for a standard loan), her holding costs drop. She also benefits from negative gearing if her rental income is less than expenses. But the CGT risk is real. By comparing loan products on ozLoan, she could find a loan with a two-year fixed period to match her planned exit, or a variable loan with a redraw facility to minimise interest.

The lesson: don’t just focus on the property—compare your mortgage options to align with your tax strategy.

FAQ: Your Burning Questions Answered

Q: I’m already overseas. Does this Budget change affect me now? A: Yes, the rules apply from July 1, 2026. If you’re currently a non-resident and sell after that date, the new exemption caps apply. If you sell before June 30, 2026, you’re still under the old rules. So if you’re planning a sale, consider timing carefully.

Q: Can I avoid CGT by returning to Australia before selling? A: Possibly. The exemption requires you to be an Australian resident at the time of sale and for at least six of the previous ten years. If you return for a few months before selling, you might qualify, but the ATO will scrutinise your intentions. A "short return" solely to avoid tax could be challenged.

Q: What if I never rent out my home while overseas—just leave it empty? A: The Budget also removes the "absence concession" for properties left empty. Previously, you could leave your home unoccupied for up to six years and still claim the exemption. Now, it’s capped at four years. So even if you don’t rent, you have a four-year window.

Q: How does this affect my mortgage if I’m a non-resident? A: Most lenders require you to notify them if you move overseas. Your loan may be reclassified as an investment loan, often with a higher rate. Compare expat-specific loans to avoid paying a premium. Some lenders, like HSBC or NAB, offer non-resident mortgages with competitive rates.
