Rentvesting flips the traditional homeownership script. You rent where you want to live and buy an investment property where the numbers work. The lifestyle trade-offs get plenty of attention. What gets less coverage is the tax position this creates, and it is significantly more favourable than what owner-occupiers get.
If you are new to the strategy, our rentvesting guide covers the fundamentals. This article focuses specifically on the rentvesting tax benefits you unlock by holding a property as an investment rather than living in it, and the deductions you can claim as a result.
Why Rentvestors Get Tax Deductions Owner-Occupiers Do Not
The distinction is simple. According to the ATO, you can claim a deduction for expenses that relate to a rental property you own if the expenses are incurred in gaining or producing your assessable rental income. Your property must be either used to produce assessable income (rented to a tenant) or held to produce assessable income on commercial terms.
Owner-occupiers fail this test entirely. Their property is not producing assessable income, so none of the ongoing costs are deductible. The mortgage interest, the insurance, the council rates, the repairs: all paid from after-tax dollars with no offset.
When you rentvest, the same categories of expense become deductible because your property is generating rental income. That single structural difference, owning for investment rather than occupation, opens up a range of deductions that can meaningfully reduce your taxable income each year.
Loan Interest: The Largest Deduction
For most rentvestors, interest on the investment loan is the single biggest deduction available.
The ATO states that if you use the principal amount to buy a rental property and it is rented or held to produce assessable income for the entire income year, you can claim a deduction for the interest charged on the loan.
This applies to interest on money borrowed to:
- Buy the rental property itself
- Purchase depreciating assets for the property, such as an air conditioner
- Pay for deductible expenses, such as repairs arising from renting the property out
- Finance renovations and extensions to the rental property
The key rule is that the loan must be used for the investment property. If you use part of the loan for private purposes (buying a car, funding a holiday), you can only claim the portion that relates to the rental property. The ATO provides a formula: total interest expenses multiplied by the rental property loan amount divided by total borrowings equals your deductible interest.
You also cannot claim the principal repayments themselves. Only the interest component is deductible.

Depreciation: Plant and Equipment
Your investment property contains assets that lose value over time. The ATO calls these depreciating assets, and according to the ATO, they are items that can be described as plant, that do not form part of the rental property premises. Under the uniform capital allowance rules, you can claim a deduction for the decline in value of depreciating assets used for income-producing purposes.
Common examples include:
- Floating timber flooring
- Carpets and curtains
- Appliances like a washing machine or fridge
- Furniture
- Air conditioners and stoves
For assets costing $300 or less, you can claim an immediate deduction in the income year you use the asset for a taxable purpose. For assets above $300, you claim the decline in value over the asset's effective life.
There is an important limitation for second-hand properties. Since the 2017 budget changes, the rules around claiming depreciation on previously used assets have tightened. Our depreciation schedule guide breaks down what you can and cannot claim depending on whether you bought new or established.
A quantity surveyor can prepare a report at the time you purchase a rental property, identifying every claimable asset and its effective life. This is worth doing early because depreciation deductions are easy to miss without a professional assessment.
Capital Works Deductions
Beyond plant and equipment, the building structure itself may be depreciable.
According to the ATO, the rate of deduction for capital works is generally 2.5% or 4% per year, spread over a period of 40 or 25 years respectively. You can only claim a deduction for capital works on rental properties once construction has been fully completed, and the property must have been built after 17 July 1985.
Capital works expenses include:
- Building and construction costs
- Alterations to the building
- Major renovations to a room
- Substantial renovations to a property
- Adding a fence, garage, patio, driveway or retaining wall
Preliminary expenses such as architect fees, engineering fees, surveying fees, foundation excavation expenses and costs of building permits also form part of construction expenses, according to the ATO.
On a property with $300,000 in eligible construction costs, a 2.5% capital works deduction returns $7,500 per year. Over the 40-year claim period, that is a significant reduction in taxable income that owner-occupiers simply cannot access.
Immediate Deductions: The Day-to-Day Costs
Beyond the big-ticket items, rentvestors can claim a range of ongoing expenses immediately in the year they are incurred. The ATO lists these as deductible provided the property is held to produce assessable income:
- Advertising for tenants
- Body corporate administrative fund fees and charges
- Council rates, water charges, land tax
- Cleaning, gardening and lawn mowing
- Pest control
- Insurance (building, contents, public liability, loss of rent)
- Property agent's fees and commission
- Repairs and maintenance
- Legal expenses related to managing the rental
Every one of these costs is also paid by owner-occupiers, but none of it is deductible for them. The rentvesting tax benefits here are not exotic. They are the same expenses every property owner faces, just treated differently by the tax system because the property produces assessable income.
For our full breakdown of every category, see our investment property tax deductions guide.
Borrowing Expenses
The costs you incur to set up the loan are also deductible, though not all at once.
According to the ATO, you must claim a deduction for all eligible borrowing expenses over 5 years or the term of the loan, whichever is shorter. If the total deductible borrowing expenses are $100 or less, they are fully deductible in the income year you incur them.
Claimable borrowing expenses include:
- Loan establishment fees
- Lender's mortgage insurance (where billed to you)
- Title search fees your lender charges
- Costs for preparing and filing mortgage documents, including solicitor fees
- Mortgage broker fees
- Fees for a valuation required for loan approval
- Stamp duty on the mortgage (not the property transfer itself)
Stamp duty on the property transfer is not deductible as a borrowing expense. However, it forms part of the cost base for capital gains tax purposes when you eventually sell.
Negative Gearing: When Expenses Exceed Income
This is where all of the above comes together. When your total deductible expenses (interest, depreciation, capital works, management fees, insurance, rates, repairs) exceed your rental income, you are in a negative gearing position.
That net rental loss reduces your total taxable income from other sources, including your salary. If you earn $100,000 and your rental property generates a net loss of $10,000 after all deductions, your taxable income drops to $90,000. At a marginal tax rate of 37 cents in the dollar, that is a tax saving directly tied to holding the investment property.
Owner-occupiers cannot create this position. Their property costs are not deductible, so there is no loss to offset against other income.
Our guide to negative gearing covers the mechanics in detail, including the 2026 federal budget changes and how negative gearing interacts with capital gains tax.
What You Cannot Claim
Not every cost associated with your investment property is deductible. The ATO makes clear you cannot claim:
- Principal loan repayments, only the interest component
- Interest on any portion of the loan used for private purposes
- Stamp duty on the property transfer (this is a capital cost, not a deduction)
- Acquisition costs like conveyancing and solicitor fees for the purchase (also capital costs, but included in your CGT cost base)
- Travel expenses to inspect residential rental properties (restricted since 2017)
The distinction between capital costs and deductible expenses matters. Capital costs are not lost to you. They form part of the property's cost base for CGT purposes, reducing your capital gain when you sell.
The Requirement: Genuinely Available for Rent
One condition underpins all of these deductions. The ATO states that your rental property must be rented out or available to rent on commercial terms to claim deductions for your expenses.
Factors that satisfy this include the property being advertised in ways that give it broad exposure to possible tenants, rental terms (including rate of rent) being similar to comparable properties in the same area, and requests to rent the property being actively monitored.
For rentvestors, this is straightforward. Your investment property is rented to a tenant at market rate, managed by an agent, and producing assessable income. You are not using it as a holiday home or renting it to family below market rates. The structure of rentvesting naturally satisfies the conditions the ATO requires for full deductibility.
Next Steps
The rentvesting tax benefits covered here — interest deductibility, depreciation, capital works, immediate operating deductions, and the ability to negatively gear — are not niche strategies. They are the standard tax treatment for any property held as an investment. Rentvesting simply ensures your property qualifies.
Understanding these deductions before you buy is critical. The right property in the right location will not just deliver rental income and capital growth. It will also create a tax position that works in your favour from year one.
