Investment Property Expenses That Could Affect Your Tax Return

Author : Garnet Accounting | Published On : 18 Sep 2026

Owning an investment property can create a valuable source of income, but it also comes with a long list of ongoing expenses. 

From property management fees and repairs to council rates, insurance and loan interest, these costs can quickly add up. The challenge is knowing which expenses may be deductible and which ones need to be treated differently for tax purposes.

Getting this wrong can mean claiming an expense incorrectly, overlooking legitimate deductions, or keeping inadequate records when you need to substantiate a claim.

Your investment property expenses can have a direct impact on your taxable rental income and, ultimately, your tax return. However, not every cost associated with a property can simply be deducted in the year you pay it.

If you own an investment property and are preparing your tax return in Midland, understanding how common property expenses are treated can help you keep better records and have a more productive discussion with your tax professional.

Why Investment Property Expenses Matter at Tax Time

Rental income is generally included when calculating your taxable income, but certain expenses associated with earning that income may be deductible if the relevant tax requirements are met.

This means your tax position is not based simply on how much rent you receive.

You also need to consider the expenses connected with generating that rental income.

For example, if you receive rental income throughout the year but pay property management fees, council rates, insurance premiums and eligible repair costs, those expenses may affect the amount of taxable rental income you report.

The important distinction is that eligibility, timing and record keeping all matter.

An expense does not automatically become deductible simply because you paid it for an investment property.

Property Management Fees and Commissions

If you use a property manager to manage your rental property, their fees and commissions are common expenses that may be relevant to your tax return.

Property managers may charge fees for services such as finding tenants, collecting rent, managing the property and handling routine administration.

Where an expense is incurred in connection with earning rental income and meets the applicable requirements, it may be deductible.

Keep copies of management statements, invoices and other relevant records.

These documents can make it easier to identify exactly what you paid during the financial year.

If your property manager provides an annual statement summarising rental income and expenses, retain it with your other tax records.

Repairs and Maintenance

Repairs and maintenance can be a major expense for investment property owners.

A repair generally addresses damage, deterioration or wear and tear and restores an existing item or part of the property to its previous condition.

Examples can include repairing a leaking tap, fixing damaged flooring or replacing a broken component.

However, not every building-related expense is treated as an immediate deduction.

The distinction between a repair and an improvement is important.

An improvement may provide something substantially different or better than what was previously there. Depending on the circumstances, the tax treatment can differ from an ordinary repair.

This is one area where professional advice can help prevent incorrect claims.

Property Improvements May Be Treated Differently

Replacing an old item with a significantly better or more substantial alternative may not qualify as an immediate repair deduction.

For example, if you replace an existing basic feature with a substantially upgraded version, the expenditure may be considered an improvement rather than a simple repair.

The cost may need to be treated under a different tax rule and potentially claimed over time rather than entirely in the year you incur it.

This is why keeping invoices and descriptions of work is important.

Do not rely solely on the label used by a contractor.

The actual nature and purpose of the work can determine its tax treatment.

Council Rates and Property Charges

Council rates are another recurring expense for many rental property owners.

Where the property is being used to generate rental income and the relevant requirements are met, council rates may be deductible.

Keep your council notices and payment records.

If the property is not rented for the entire year, the timing and circumstances may affect how expenses are treated.

For example, a property may be vacant between tenants or may be temporarily unavailable for rent.

Your tax professional can assess the circumstances and determine the appropriate treatment.

Land Tax Can Affect Your Tax Position

Land tax is another expense that some investment property owners need to consider.

The rules surrounding land tax can be complex and can vary depending on the property, ownership structure and applicable state or territory requirements.

If you own multiple properties, land tax considerations can become particularly important.

Keep all relevant land tax assessments and payment records.

Do not assume that every property-related government charge receives the same tax treatment.

Insurance Costs

Investment property insurance can cover risks associated with the property and its rental use.

Depending on the nature of the policy and the applicable tax rules, certain insurance expenses may be relevant deductions when calculating taxable rental income.

Keep records of premiums paid and the type of insurance coverage.

This can include documentation for building insurance, landlord insurance and other relevant policies.

If you receive an insurance payout following damage to the property, make sure you also provide the relevant details to your tax professional because the tax treatment can depend on the circumstances.
 

Loan Interest and Borrowing Costs

For many property investors, financing costs represent one of the largest expenses associated with owning a rental property.

Interest on a loan used to acquire or produce income from an investment property may be deductible, subject to the applicable rules.

However, you should not assume that every amount appearing on your home loan statement is deductible.

The purpose of the borrowing matters.

If a loan has been refinanced, redrawn or used partly for private purposes, the tax treatment can become more complicated.

Keep loan statements and documentation showing how borrowed funds were used.

If the loan has multiple purposes, seek professional advice rather than simply claiming the full interest amount.

Borrowing Costs May Need to Be Claimed Over Time

Some costs associated with taking out a loan may not be treated in the same way as regular loan interest.

Certain borrowing expenses may need to be deducted over a period rather than claimed entirely in the year they are paid, depending on the applicable tax rules.

Examples can include certain loan establishment costs and other expenses connected with obtaining finance.

Because the treatment can depend on the type and amount of expense, keep all loan documentation.

Your tax professional can determine how the cost should be treated in your return.
 

Depreciation and Decline in Value

Investment property owners may also need to consider deductions associated with the decline in value of eligible depreciating assets.

Items such as certain appliances, equipment and fixtures can lose value over time.

The tax treatment depends on the asset, its use, when it was acquired, and the applicable rules.

Building-related deductions can involve a separate set of rules.

This area can become complicated, particularly for properties that have changed ownership or have undergone renovations.

A professional assessment can help determine which deductions may be available and how they should be calculated.

Pest Control and Property Maintenance

Routine costs associated with maintaining a rental property can add up over the course of a year.

Pest control, gardening, cleaning, pool maintenance and other services may be relevant to your tax return where they are incurred in connection with earning rental income and satisfy the relevant requirements.

Keep invoices rather than relying on bank statements alone.

An invoice should ideally identify the property, service provided, date and amount paid.

Good documentation makes it easier to establish what the expense relates to.
 

Advertising for Tenants

Finding tenants can involve advertising costs.

You may pay for online listings, property advertising, photography or other marketing services when preparing a property for rent.

Where the expense meets the applicable requirements for a rental property, it may be relevant to your tax return.

Keep receipts and invoices from advertising providers and property agents.

If you own multiple properties, make sure you can identify which property the expense relates to.

Legal and Professional Fees

Property investors may incur legal, accounting or professional fees during the year.

Some expenses may be deductible where they relate directly to managing or generating rental income.

However, professional fees associated with acquiring a property or dealing with capital matters can have different tax treatment.

For example, the cost of obtaining professional advice during a property purchase should not automatically be treated in the same way as an ongoing property management expense.

The purpose of the expense matters.

Travel and Motor Vehicle Expenses Require Care

Property owners sometimes incur travel costs when inspecting or managing an investment property.

However, travel-related tax deductions have specific rules and limitations.

You should not assume that driving to your rental property automatically creates a deductible expense.

The circumstances, timing and purpose of the travel matter.

Keep detailed records of relevant expenses and discuss them with your tax professional before making a claim.

This is particularly important if the property is interstate or if your travel combines private and property-related activities.

What About Interest Before the Property Is Rented?

An investment property may sit vacant before a tenant moves in.

You may still have expenses during this period, but the tax treatment depends on whether the property is genuinely available for rent and the circumstances involved.

For example, there can be an important distinction between a property being actively advertised and available to tenants and a property being held for private use.

Keep evidence showing when the property was available for rent.

Rental listings, property management agreements and advertising records can help establish the circumstances surrounding the property.

Expenses When a Property Is Vacant

A property can remain vacant for several reasons.

There may be a gap between tenants, maintenance may be underway, or the property may be temporarily unavailable.

Vacancy does not automatically mean every expense becomes non-deductible.

The relevant question is often whether the property continues to be held and used in a way that satisfies the requirements for claiming the expense.

Keep records explaining periods of vacancy and any steps taken to find a tenant.

Your tax agent can assess the circumstances rather than relying on the vacancy period alone.

What Happens When You Sell the Investment Property?

Selling an investment property can introduce another layer of tax considerations.

The expenses associated with buying, owning and selling the property do not necessarily all receive the same treatment.

Capital gains tax may apply when an investment property is sold, subject to the applicable rules and your individual circumstances.

Certain costs may form part of the property's cost base rather than being treated as ordinary rental deductions.

This is why you should retain records from the moment you purchase the property, not just documents from the current financial year.

Why Good Record Keeping Matters

Many investment property tax problems begin with poor records.

You may remember paying for a repair but struggle to locate the invoice months later.

Or you may have several properties and cannot remember which expense relates to which one.

Good record keeping should start as soon as you incur an expense.

Keep:

  • Invoices and receipts
  • Property management statements
  • Loan statements
  • Council rate notices
  • Insurance documents
  • Land tax records
  • Repair and maintenance invoices
  • Advertising records
  • Depreciation information
  • Relevant legal and professional invoices

Digital storage can make these documents easier to organise and retrieve.

Common Mistakes Property Investors Make

One of the most common mistakes is treating every property expense as an immediate deduction.

Another is claiming private expenses simply because they relate to a property that also earns rental income.

Investors may also overlook the difference between repairs and improvements or fail to keep sufficient evidence to support a claim.

Another issue is failing to account for changes in property use.

If you move into the property, stop renting it, change the ownership structure, or use it partly for private purposes, the tax treatment can change.

When your circumstances change, review your tax position rather than continuing to use the same approach automatically.

When Should You Speak to a Tax Professional?

Investment property tax can become complicated quickly.

Professional advice can be particularly valuable if you own multiple properties, have complex borrowing arrangements, have renovated a property, have recently purchased or sold an investment property, or are unsure whether an expense is immediately deductible.

A tax professional can review your records and help identify the correct treatment for different expenses.

This can help you avoid both sides of the problem: claiming something incorrectly and overlooking a legitimate deduction.

Preparing Your Investment Property Information for Tax Time

Before your tax appointment, organise your property information in one place.

Prepare a summary of rental income and collect supporting documents for your expenses.

Separate expenses by property if you own more than one.

Keep loan information separate from general property expenses so borrowing costs can be reviewed accurately.

If you completed renovations or major improvements, keep detailed invoices and contracts rather than grouping everything under "repairs."

The more organised your records are, the easier it is to prepare an accurate return.

Conclusion

The most important step is not simply keeping receipts. It is understanding what each expense relates to, when it was incurred, how the property was being used, and whether the applicable tax rules allow the expense to be claimed.
