Common Rental Property Tax Mistakes in 2026

The most common rental property tax mistakes in 2026 are usually not dramatic.

They are simple things done badly.

Common mistakes include:

• not declaring all rental income

• declaring only the net amount received from the agent

• relying only on the property manager statement

• claiming private-use periods

• claiming travel to inspect or repair the property

• claiming improvements as repairs

• claiming initial repairs incorrectly

• claiming full loan interest after private redraws

• ignoring Airbnb or holiday-home private use

• missing depreciation or capital works records

• double claiming expenses already shown on the agent statement

• keeping poor records

Rental property tax is not just rent minus random expenses.

That would be nice.

It would also be wrong.

Mistake 1: Not declaring all rental income

Rental income is not just the money that lands in your bank account.

You may need to declare:

• rent paid by tenants

• rent paid to your property manager

• short-term rental income

• Airbnb income

• Stayz income

• insurance payouts for lost rent

• tenant reimbursements

• bond money you are entitled to keep

• overseas rental income

• direct payments outside the agent statement

The big trap is declaring only the net amount transferred to you by the property manager.

Example:

Item	Amount
Rent paid by tenant to agent	$28,000
Agent fees and expenses deducted	$4,000
Net amount transferred to owner	$24,000

The income is not simply $24,000.

The tax return needs to consider the gross rent and the expenses separately.

The agent is helpful.

The agent is not a tax invisibility cloak.

---

Mistake 2: Relying only on the property manager statement

A property manager statement is useful.

It may show:

• rent received

• agent fees

• letting fees

• repairs paid by the agent

• advertising

• cleaning

• gardening

• water charges

• tenant payments

• net payments to you

But it may not show everything.

Common missing items include:

• loan interest

• council rates paid directly

• water rates paid directly

• landlord insurance

• body corporate fees

• depreciation schedule

• borrowing expenses

• settlement adjustments

• repairs paid directly by you

• legal fees

• land tax

• private-use periods

• Airbnb income outside the agent

• loan redraw issues

The agent statement is a starting point.

It is not the full tax return.

If you upload the agent statement and ignore the rest, you may miss deductions or lodge an incomplete rental schedule.

That is the worst of both worlds.

Less refund.

More risk.

Excellent. Nobody ordered that.

Mistake 3: Claiming expenses when the property was not genuinely available for rent

Rental deductions generally depend on the property being rented out or genuinely available for rent.

This matters where the property was:

• vacant

• being repaired

• being renovated

• used privately

• blocked out for owner use

• held for family use

• not advertised

• advertised at unrealistic rent

• available only under unreasonable conditions

A normal vacancy between tenants may be fine.

A property kept empty for private use is different.

A holiday home blocked out over Christmas and school holidays while technically listed online is also different.

The tax return needs to look at the facts.

Not the vibe.

Tax does not accept “it was sort of available”.

That is a phrase, not evidence.

---

Mistake 4: Claiming rental travel costs

For ordinary individual landlords, travel to inspect, maintain, repair or collect rent for a residential rental property is generally not deductible.

That means you generally should not claim:

• fuel

• kilometres

• flights

• accommodation

• meals

• Uber or taxi fares

• hire cars

• parking

• tolls

• travel to meet the agent

• travel to do repairs yourself

This catches people because the trip may genuinely relate to the rental property.

You may have actually inspected damage.

You may have actually met the property manager.

You may have actually repaired something.

The problem is that the travel itself is generally denied.

The practical distinction is:

Cost	Practical treatment
Your travel to inspect the property	Generally not deductible
Your travel to do repairs	Generally not deductible
Property manager inspection fee	May be deductible if rental-related
Tradesperson repair invoice	May be deductible if it qualifies
Materials for genuine repair	May be deductible if it qualifies

Do not claim the owner travel.

Do check the actual repair or property manager cost.

Mistake 5: Claiming improvements as repairs

This is one of the biggest rental property mistakes.

A repair usually fixes damage, wear or deterioration.

An improvement usually makes the property better, adds something new, replaces something substantial, or forms part of a renovation.

Examples:

Cost	Common issue
Fix broken tap	More likely repair
Repair damaged fence section	More likely repair
Replace cracked window pane	More likely repair
Replace entire kitchen	Usually improvement or capital issue
Renovate bathroom	Usually capital issue
Add deck	Capital improvement
Replace all flooring	Needs review
Replace entire roof	Needs review

Do not rely only on the invoice heading.

An invoice saying “repairs” does not automatically make it a repair.

If that worked, every renovation invoice in Australia would say “repair”.

Tax law has met tradie invoices before.

---

Mistake 6: Claiming initial repairs immediately

Initial repairs are another major trap.

An initial repair is generally work done to fix damage, defects or deterioration that existed when you bought the property.

These costs are often capital in nature.

That means they may not be immediately deductible as repairs.

Example:

You buy a rental property.

The bathroom is damaged at settlement.

Before renting it, you fix the bathroom.

It feels like a repair.

But if the damage existed when you bought the property, it may be an initial repair and not immediately deductible.

This is especially important for first-year landlords.

The timing matters.

The condition at purchase matters.

The reason for the work matters.

Unfortunately, “I had to fix it before renting the place” is not the whole tax answer.

Mistake 7: Claiming full loan interest after private redraws

Loan interest is often the biggest rental deduction.

It is also one of the biggest ATO focus areas.

The key question is:

What was the borrowed money used for?

If the loan was used to buy the rental property, the interest may be deductible.

But if you redraw from the rental loan and use the money privately, the interest on that private portion may not be deductible.

Private redraws may include:

• buying a family car

• paying school fees

• renovating your own home

• paying private bills

• funding a holiday

• helping family members

• paying personal credit cards

The bank may still show one loan.

Tax may see two purposes.

That means the interest may need to be apportioned.

The bank name is not enough.

The money trail matters.

Mistake 8: Confusing redraw and offset accounts

Redraw and offset accounts are not the same thing.

This mistake can affect rental loan interest claims.

A redraw usually involves taking money back out of the loan after extra repayments have been made.

The purpose of the redrawn money matters.

If the redraw is used privately, that part of the interest may become non-deductible.

An offset account is usually a separate account linked to the loan.

Money sitting in the offset reduces interest charged on the loan, but withdrawing money from an offset account may not have the same tax consequences as redrawing from the loan.

This is why landlords should be careful before moving money around.

Convenient banking can create inconvenient tax records.

If your loan history includes redraws, refinancing, offset accounts or mixed-use funds, keep the records.

Future you will either be grateful or furious.

Choose grateful.

Mistake 9: Ignoring holiday home and Airbnb private use

Holiday homes and Airbnb properties need extra care.

You may need to track:

• days rented

• days available for rent

• owner-use days

• family-use days

• friends staying free

• friends staying cheaply

• blocked dates

• peak periods kept for private use

• repair periods

• cleaning periods

• platform fees

• direct bookings

The mistake is treating a holiday home like a normal full-time rental property.

It may not be.

If the property is partly used privately, deductions may need to be reduced.

If peak rental periods are blocked out for family use, the position can become even weaker.

A beach house listed online for quiet weeks but kept for Christmas, Easter and school holidays is not the same as a property genuinely prioritised for rental income.

The calendar matters.

The calendar is basically the witness that never forgets.

Mistake 10: Claiming full-year expenses for a part-year rental

If the property was rented or available for only part of the year, some expenses may need to be apportioned.

This can happen where:

• the property was purchased during the year

• the first tenant moved in part-way through the year

• the property changed from your home to a rental

• the property changed from rental to private use

• the property was sold

• the property was used privately

• the property was unavailable for substantial renovations

Do not automatically claim the full year.

Check the dates.

Dates that matter include:

• settlement date

• date first advertised

• date first available for rent

• date first tenant moved in

• vacancy dates

• private-use dates

• renovation dates

• sale date

Tax time loves dates.

Landlords often do not.

Tax time wins.

---

Mistake 11: Getting off-market repair periods wrong

Sometimes a rental property is temporarily off the market for repairs or maintenance.

That does not automatically mean all rental deductions are lost.

A short period for genuine minor maintenance or repair may be treated differently from a property taken off-market for substantial renovation.

The practical distinction is:

Situation	Tax issue
Minor repair between tenants	Holding costs may still be okay depending on facts
Property still genuinely rental-focused	Stronger position
Major renovation before rental use resumes	Needs closer review
Substantial renovation	Holding costs may be affected
Property not lawfully able to be occupied	Higher risk
Property not genuinely available for rent	Deductions may be limited or denied

Do not treat every off-market period the same.

A leaking tap and a full rebuild are not twins.

Tax law knows the difference.

So should the return.

---

Mistake 12: Splitting income and expenses incorrectly between co-owners

If a rental property is co-owned, income and deductions usually follow legal ownership.

Examples:

Ownership	Usual split
50/50 joint owners	50/50
Tenants in common 70/30	70/30
Joint tenants	Usually equal shares

Do not give the bigger deduction to the person with the higher income because it looks better.

Do not split the rent based only on who paid the mortgage.

Do not change the split because one person “handled the property”.

The legal ownership usually matters.

The title deed is not interested in household tax optimisation.

Rude, but consistent.

---

Mistake 13: Double claiming expenses

This happens more often than people think.

The property manager statement may already include expenses such as:

• repairs

• agent fees

• water usage

• advertising

• cleaning

• gardening

• pest control

• inspection fees

If you also enter the same invoice separately, you may double claim it.

Example:

The property manager statement includes a $750 plumbing repair.

You also enter the plumber’s invoice separately.

That may claim the same expense twice.

Check whether the expense was:

• paid by the agent from rent

• paid directly by you

• reimbursed by you to the agent

• included in the annual statement

• duplicated in bank records

Double claiming is not “being thorough”.

It is being wrong twice.

---

Mistake 14: Missing deductions that are not on the agent statement

The opposite mistake also happens.

Landlords miss deductions because they assume the agent statement has everything.

It may not.

Common missed items include:

• loan interest

• council rates

• landlord insurance

• building insurance

• body corporate fees

• depreciation schedule

• borrowing expenses

• bank fees

• land tax

• repairs paid directly

• legal costs

• tax agent fees

• quantity surveyor fees

• settlement adjustments

This is why the property manager statement is both helpful and dangerous.

It gives you some of the picture.

It can also make you forget the rest.

Like a very confident half-map.

---

Mistake 15: Not keeping enough records

Good records are the difference between a claim and a guess.

Keep records for:

• rental income

• property manager statements

• loan interest

• rates

• insurance

• body corporate fees

• repairs

• maintenance

• depreciation

• capital works

• borrowing expenses

• private use

• vacant periods

• holiday home calendars

• Airbnb bookings

• ownership percentage

• purchase and sale documents

• settlement statements

• refinance and redraw records

Rental property records generally need to be kept for the required tax record period.

Some records should be kept longer because they may affect capital gains tax later.

That includes purchase records, improvement records and capital works records.

Do not throw out property documents because the year’s tax return is done.

Property records have a long tail.

Like a tax lizard.

---

Mistake 16: Claiming ATO interest charges as a deduction

This is a 2026 trap.

From 1 July 2025, general interest charge and shortfall interest charge are generally no longer deductible.

That means ATO interest is not the same as rental property loan interest.

Do not confuse:

Interest type	Treatment issue
Bank interest on rental property loan	May be deductible if connected to rental purpose
Interest on private redraw portion	Not deductible to the extent private
ATO general interest charge	Generally not deductible from 1 July 2025
ATO shortfall interest charge	Generally not deductible from 1 July 2025

If the ATO charges interest because tax was paid late or amended, do not just drop it into rental interest.

That is a different animal.

A crankier one.

---

Mistake 17: Thinking a rental loss automatically means a refund

A rental loss does not automatically mean a refund.

The final tax result depends on:

• rental income

• rental expenses

• employment income

• tax withheld

• other income

• deductions

• Medicare levy

• HELP debt

• offsets

• prior year issues

• ATO processing

Negative gearing can reduce taxable income where the deductions are correct.

But it is not a magic refund machine.

The rental loss needs to be based on proper income, proper deductions and proper records.

A bad rental loss is not negative gearing.

It is just a problem with a minus sign.

Common rental mistakes checklist

Before lodging, check:

• Have you declared all rental income?

• Did you include rent paid to the property manager?

• Did you include Airbnb or short-term rental income?

• Did you check insurance payouts and tenant reimbursements?

• Are you using gross rental income, not just net transfers?

• Did you include expenses paid outside the agent statement?

• Did you avoid double claiming agent-paid expenses?

• Did you check loan purpose and redraws?

• Did you separate repairs from improvements?

• Did you check initial repairs?

• Did you remove private-use periods?

• Did you avoid owner travel claims?

• Did you keep records for vacant periods?

• Did you keep Airbnb and holiday home calendars?

• Did you split co-owned property correctly?

• Did you avoid claiming ATO interest charges?

• Did you keep purchase and improvement records for future CGT?

If you cannot answer those clearly, pause before lodging.

Rental property mistakes are much easier to fix before lodgement than after the ATO asks questions.

ATO questions rarely arrive with snacks.

Frequently asked questions

What is the biggest rental property tax mistake?

One of the biggest mistakes is relying only on the property manager statement and missing income, expenses, loan interest, private-use issues or records outside that statement.

Do I declare the rent before or after agent fees?

You generally need to consider the gross rent, with agent fees and other deductible expenses recorded separately.

Can I claim travel to inspect my rental property?

Generally no. Ordinary individual landlords usually cannot claim travel costs to inspect, maintain, repair or collect rent for residential rental properties.

Can I claim all loan interest on my rental property?

Only where the borrowed money relates to the rental property or rental purpose. Private redraws, refinancing and mixed-purpose loans may require apportionment.

Can I claim renovations as repairs?

Usually not. Renovations and improvements often need different tax treatment and may need to be claimed over time.

What are initial repairs?

Initial repairs are costs to fix defects, damage or deterioration that existed when you acquired the property. They are often capital in nature.

Do I need Airbnb records?

Yes. Keep platform statements, gross income records, booking calendars, private-use dates, blocked dates and expense records.

Can a rental loss increase my refund?

A rental loss may reduce taxable income if the deductions are correct, but it does not automatically mean a refund.

Can GoTax help avoid rental property tax mistakes?

Yes. GoTax helps Australian rental property owners complete tax returns online, with returns checked by registered tax agents before lodgement.
