Paying tax on your investment property is an inevitable part of building wealth, but managing your position correctly can significantly improve your returns each year. A solid tax strategy keeps your cash flow healthy and keeps you fully compliant with the Australian Taxation Office. Get it wrong and you erode profits or trigger an unwanted audit; get it right and you keep more money in your pocket to fund your next purchase or pay down debt faster.

This guide breaks down the rules, from declaring rental income to mastering depreciation, capital gains tax and gearing, and it flags the major reforms now reshaping the landscape. Securing the right property is only the first step; structuring the finances well is the next, and it is where the Amassed team helps investors align each purchase with a sound long-term position. It is general information only, not personal tax advice.

How Is Rental Income Taxed in Australia?

The ATO treats your rental income as assessable income, so you must declare every dollar you earn from tenants in the financial year you receive it. Your assessable income goes beyond the weekly rent. If you retain part of a tenant’s bond to cover damage, that money is assessable, as is any insurance payout for damage or lost rent, and any separate payments a tenant makes for water usage.

Accuracy matters because the ATO runs sophisticated data-matching that cross-references information from agents, banks and bond authorities. Reporting your exact income starts your return on the right foot and keeps you clear of compliance problems, which is the foundation of getting the rest of your investment property tax guide right, since every deduction you claim is measured against the income you have declared.

What Can You Claim Immediately?

One of the major benefits of property investing is claiming the expenses you incur while generating rental income, and many are deductible in the same year you pay them. These immediate investment property tax deductions are where most investors improve their annual position.

The largest immediate deductions

The biggest is usually the interest on your investment loan, which you can claim in full, along with ongoing bank fees, though never the principal portion of a repayment. Property management fees, letting fees and advertising for tenants are fully deductible. So are your ongoing holding costs: council rates, water service charges, body corporate fees on strata properties, and landlord, building and contents insurance premiums.

Repairs versus improvements

Repairs and maintenance are also immediately deductible, where a repair restores something to its original condition, such as fixing a leaking pipe, replacing a broken window pane or mending a fence. The distinction from an improvement is critical and is a common audit trigger, so it is worth getting right from the start. A useful test is whether the work restores the original function, which is a repair, or upgrades it, which is capital. If cash flow is central to your strategy, our guide to positive cash flow property shows how these deductions fit the bigger picture.

Certain borrowing costs deserve a mention because they are treated differently again. Loan establishment fees, lender’s mortgage insurance and title search fees related to the loan are generally deductible, but spread over the shorter of five years or the loan term rather than claimed all at once. Getting the timing of each expense right, immediate, depreciated, spread or added to the cost base, is exactly where a registered tax agent earns their fee, and it is also why a single missed category can quietly cost you thousands across a year.

What Costs Are Not Immediately Deductible?

Many investors wrongly claim costs that are not eligible for an immediate deduction, so understanding the exclusions protects you. Capital improvements are the main one: work that makes an asset better than its original state, such as upgrading a laminate benchtop to stone or installing air conditioning where none existed, cannot be claimed immediately. Instead you depreciate it over time or add it to your cost base.

Travel expenses are also excluded. Since 1 July 2017, individual investors cannot claim the cost of inspecting a residential rental property, so flights, petrol and accommodation for property visits are out. Pre-rental expenses catch people too: renovations completed before the property is available to rent are initial repairs or capital improvements, not immediate deductions, because the property was not yet generating income. And you cannot claim expenses for periods of private use, so if you holiday in the property you must apportion costs to exclude those days.

How Does Property Depreciation Work?

Depreciation is widely considered the most powerful deduction for investors because it is non-cash: you claim the natural wear and tear of the building and its assets without spending money during the year. Understanding property depreciation australia rules can turn a negatively geared property into a manageable one.

Capital works versus plant and equipment

There are two categories. Capital works deductions, under Division 43, cover the structural elements: bricks, concrete, roofing, fixed wiring, retaining walls and driveways. For residential property built after 15 September 1987, you can generally claim 2.5 per cent of the original construction cost each year for 40 years, based on construction cost rather than purchase price. Plant and equipment deductions, under Division 40, cover removable fixtures like carpets, dishwashers, blinds, ovens and hot water systems, each depreciating over an effective life the ATO sets, so a dishwasher might run to ten years and curtains to six.

Methods, pooling and scrapping

For plant and equipment you choose a method in the first return and cannot change it later. The diminishing value method front-loads deductions into the early years, which helps cash flow with a new mortgage, while the prime cost method spreads them evenly for predictability. Items costing under $1,000 can go into a low-value pool that depreciates at 37.5 per cent a year, and when you renovate and discard old assets like carpet or a broken stove, scrapping lets you claim their remaining value immediately.

Eligibility, the 2017 rule and getting a schedule

The construction date drives eligibility, and the 9 May 2017 change is the one to know: if you exchanged contracts on a second-hand residential property after that date, you cannot claim depreciation on the existing plant and equipment, though you can still claim capital works on the structure and full depreciation on brand-new assets you install yourself. Brand-new and commercial properties are treated differently, and older homes can still qualify for capital works if a previous owner renovated after 26 February 1992, so a 1970s house with a modern extension or updated bathroom can still generate real deductions. Commercial buildings are more generous again, eligible from 20 July 1982 at rates between 2.5 and 4 per cent depending on construction, and commercial investors are exempt from the 2017 plant and equipment restriction entirely. To claim correctly, engage a qualified quantity surveyor to prepare a depreciation schedule, which typically costs $500 to $800, is fully deductible, and projects your deductions across 40 years. Apartment owners also claim a share of common-area assets like lifts and pools through their body corporate entitlements, which can lift the total meaningfully, and it is one reason the houses versus units decision has a tax dimension as well as a growth one.

A quick worked example

The power of depreciation is easiest to see in numbers. Say a property earns $30,000 in rent and has $15,000 of out-of-pocket deductible expenses, leaving $15,000 of net taxable rental income. Add a depreciation schedule that identifies $10,000 of non-cash deductions and that taxable figure drops to just $5,000, without a single extra dollar leaving your pocket during the year. For many investors, that is exactly what turns a property with tight or negative cash flow into a sustainable, manageable hold, which is why the schedule fee pays for itself within weeks of the first return.

How Does Capital Gains Tax Work, and What Is Changing?

When you sell, capital gains tax applies to any profit, which is added to your assessable income in the financial year you sign the contract of sale. Your gain is the sale price minus your cost base, and the cost base is more than the purchase price: it includes stamp duty, legal and conveyancing costs, buying and selling agent fees, and capital improvements, so meticulous records reduce the final bill. One nuance often missed is that capital works deductions you have already claimed reduce your cost base when you sell, which increases the gross gain. That still works out favourably for most investors, because you receive the deductions at your full marginal rate each year and, for now, a discount on the eventual gain, but it is one more reason to plan the sale rather than stumble into it.

The 50 per cent discount and the 2027 reform

For assets held longer than 12 months, individuals and trusts have long received a 50 per cent CGT discount, meaning tax on only half the gain. This is where the biggest change is coming. Under the Treasury Laws Amendment passed in 2026, the 50 per cent discount is being replaced with cost base indexation and a 30 per cent minimum tax rate on capital gains accruing after 1 July 2027, while properties held before the 12 May 2026 announcement receive grandfathering protection. Because this materially changes the maths of a long-term hold, timing and structure now matter more than ever, and deciding when to sell should factor the reform in. Always model your specific position with a registered tax professional.

Positive vs Negative Gearing: What Are the Tax Effects?

Gearing simply means borrowing to invest, and your property is either positively or negatively geared depending on its cash flow. Positive gearing is when rental income exceeds deductible expenses, producing a taxable profit you pay tax on at your marginal rate while enjoying stronger cash flow and greater borrowing capacity for your next purchase. Negative gearing australia rules allow the opposite case, where deductible expenses exceed rent, to offset the shortfall against your other income such as salary, lowering your overall tax.

The negative gearing reform

Here too, change is coming. From 1 July 2027, negative gearing for residential property will be limited to new builds, with properties held before the 12 May 2026 announcement grandfathered under the existing rules. That makes the long-standing warning more important than ever: negative gearing was never a standalone strategy, and it only works when long-term capital growth outweighs the short-term cash loss. The decision between chasing income or growth is covered in our guide to growth versus cash flow, and the tax outcome should support that strategy rather than drive it.

What State Taxes Apply?

Beyond federal income tax, investors budget for state-based taxes. Stamp duty is the largest upfront cost, a one-off tax paid on acquisition that varies by state, price and buyer type. It is not immediately deductible, but it forms part of your CGT cost base. Land tax is an ongoing annual charge on the combined unimproved land value you own above a threshold, with your main residence generally exempt.

Thresholds and rates differ sharply by state. As a rough guide the individual threshold sits around $600,000 in Queensland, roughly $1.075 million in New South Wales, and just $50,000 in Victoria, though these are indexed and change, so confirm the current figure with your state revenue office. Land tax is fully deductible against rental income. State differences like these are one reason many investors focus on Queensland, and our Brisbane buyers agents factor the full tax and cost picture into every purchase. Because these upfront and holding costs shape your real return, our guide to the investment property deposit you need sets out the full cost picture.

How Do You Keep Records and Lodge Correctly?

Good documentation is what makes the rest work. You complete a rental property schedule as part of your supplementary return, and the golden rule is to keep all relevant records for at least five years after lodging, and five years after the year you sell for anything affecting CGT. Keep loan statements, management summaries, purchase contracts, depreciation schedules and receipts for every repair and premium, and digital tracking through the year prevents missed claims and makes the eventual capital gains calculation far simpler. Poor records are the single most common reason investors either overpay tax or cannot substantiate a claim if the ATO asks.

While you can lodge yourself, a registered tax agent is highly recommended given how complex and frequently changed these rules are, and their fees are deductible. The same discipline applies as you scale, so pairing a sound tax structure with a clear plan to build a property portfolio is what compounds wealth over time. A structured feasibility study on each purchase keeps the numbers honest, and you can see how disciplined acquisition supports strong after-tax outcomes on our client results page.

Frequently Asked Questions

What can I claim as a tax deduction on an investment property?

You can generally claim loan interest, property management and letting fees, advertising, council and water rates, body corporate fees, landlord and building insurance, and repairs that restore something to its original condition. Depreciation on the building and eligible assets is also claimable. Capital improvements, loan principal, and private-use periods are not immediately deductible. Always confirm eligibility with a registered tax agent, since rules change and depend on your circumstances.

Is the 50 per cent capital gains tax discount still available?

For now, yes. Individuals and trusts holding an asset longer than 12 months currently receive a 50 per cent CGT discount. However, under the 2026 tax reform, that discount is being replaced with cost base indexation and a 30 per cent minimum tax rate on gains accruing after 1 July 2027, with properties held before the 12 May 2026 announcement grandfathered. Because this changes long-term returns, model your position with a tax professional before buying or selling.

How does property depreciation work in Australia?

Depreciation lets you claim the decline in value of your building and its assets as a non-cash deduction. Capital works (Division 43) covers the structure at 2.5 per cent a year for 40 years on eligible post-1987 buildings, while plant and equipment (Division 40) covers removable assets over their effective life. Since 9 May 2017, you generally cannot claim plant and equipment on second-hand homes. A quantity surveyor’s depreciation schedule ensures you claim everything you are entitled to.

What is the difference between a repair and a capital improvement?

A repair restores an item to its original working condition, such as fixing a broken pipe or replacing a shattered window, and is fully deductible in the same year. A capital improvement makes the asset better than before, such as replacing a laminate benchtop with stone or adding air conditioning, and cannot be claimed immediately. Instead you depreciate it over time or add it to your cost base. Mixing the two up is a common audit trigger.

Is negative gearing changing in Australia?

Yes. Under the 2026 tax reform, from 1 July 2027 negative gearing for residential property will be limited to new builds, with properties held before the 12 May 2026 announcement grandfathered under existing rules. Negative gearing lets you offset a rental shortfall against other income, but it has never been a standalone strategy and only works when capital growth outweighs the cash loss. Given the change, get current advice before relying on it.

Do I need an accountant to lodge my rental property tax return?

You can lodge yourself, but a registered tax agent is highly recommended because property tax rules are complex and change frequently, and the reforms landing in 2027 add further nuance. A good accountant ensures you claim everything you are legally entitled to while keeping you compliant, and their preparation fees are tax deductible. For depreciation specifically, you also need a qualified quantity surveyor to prepare the schedule.

Strategic Takeaways for Property Investors

Understanding property tax is an essential skill for a profitable portfolio. Claim every legitimate deduction, obtain a professional depreciation schedule, and plan for capital gains, and you accelerate your wealth creation. Prioritise clear digital record-keeping from settlement day, and treat tax benefits such as negative gearing as support for a growth-focused strategy rather than the reason to buy. The right asset still matters most, which is why a disciplined buyers agency service focuses first on the property and second on the structure around it.

Your next step

The reforms landing in 2027 make expert guidance more valuable, not less, because the right property and the right structure now interact more closely. When you are ready to find a high-performing investment aligned with your goals, a short strategy consultation can help you choose well, and you can request a free consultation whenever you want to talk it through.
