Tax Deduction Checklist for Home Loan and Property Owners

If you own an investment property, many expenses are tax-deductible. Understanding what you can claim reduces your tax liability and improves your bottom line. Here’s a checklist.

Investment property interest and costs:

Interest on investment property mortgage: fully deductible. Lenders mortgage insurance (LMI): deductible. Loan application fees: deductible. Valuation fees: deductible.

Example: AUD 400,000 mortgage at 4.5% = AUD 18,000 interest/year, fully deductible.

Running costs:

Rates (council tax): deductible. Water rates: deductible. Property insurance (landlord/building): deductible. Contents insurance (if you provide to tenants): deductible. Maintenance and repairs: deductible. Utilities (electricity, gas) if you pay: deductible.

Example: rates AUD 2,400/year, insurance AUD 1,200/year, maintenance AUD 1,500/year = AUD 5,100 in deductions.

Management costs:

Property management fees (typically 6%–10% of rent): deductible. Tenant screening/background checks: deductible. Advertising for tenants: deductible. Accounting and bookkeeping: deductible.

Example: AUD 24,000/year rent × 8% management fee = AUD 1,920 deductible.

Capital improvements vs. repairs:

Repairs (maintenance): deductible immediately. Capital improvements (adds value): not immediately deductible, but depreciable over time.

Distinction:

  • Repainting the exterior is a repair (deductible now)
  • Building an extension is capital (depreciated over time)
  • Fixing a broken window is a repair (deductible)
  • Replacing all windows is capital (depreciated)

This is a common confusion point. Talk to your accountant.

Depreciation:

Building depreciation: 2.5% of construction/building cost annually (deductible, but recaptured on sale). Plant and equipment: depreciated over useful life (kitchen, bathrooms, carpets, etc.).

Example: AUD 300,000 building value × 2.5% = AUD 7,500/year deductible.

Compliance costs:

Tax accountant fees: deductible. Legal fees (related to rental property): deductible. Body corporate notices (if apartment): deductible (the portion related to compliance/management).

What’s NOT deductible:

Principal mortgage payments: not deductible (you’re paying down asset value). Capital works (renovations that add value): not immediately deductible (depreciated over time). Negative gearing: can’t create an artificial loss to offset income from other sources (though losses can offset future years’ rental income). Personal use: if you use the property part of the year, you can’t deduct expenses for the personal-use period.

Real scenario:

Investment property:

  • Annual rent: AUD 24,000
  • Mortgage interest: AUD 18,000
  • Rates: AUD 2,400
  • Insurance: AUD 1,200
  • Maintenance: AUD 1,500
  • Management: AUD 1,920
  • Depreciation: AUD 7,500

Total deductions: AUD 32,520

Taxable rental income: AUD 24,000 - AUD 32,520 = -AUD 8,520 loss

You have a negative taxable income from the property. This loss offsets other income (salary, etc.). If you earn AUD 100,000 salary, your taxable income becomes AUD 91,480, saving tax on AUD 8,520 at your marginal rate (roughly AUD 3,150 in tax savings at 37% rate).

Recordkeeping:

Keep all receipts and invoices related to the property. The ATO requires evidence for deductions.

  • Maintenance invoices
  • Insurance certificates
  • Rates notices
  • Accountant reports

If you claim depreciation, keep asset schedules and valuations.

Common mistakes:

  1. Claiming personal use expenses: if you stay in the property one month, you can’t deduct that month’s expenses.
  2. Not splitting mixed expenses: if your accountant fee is partly personal and partly property, only claim the property portion.
  3. Claiming capital as repairs: a complete roof replacement is capital; patching tiles is repair. Know the difference.
  4. Not documenting: claiming expenses without receipts is risky if audited.

Pro tip:

Use accounting software (MYOB, Xero, Quickbooks) to track all expenses throughout the year. This makes tax time easier and ensures you capture all deductions. Most software is AUD 10–AUD 30/month.

My take:

Tax deductions for investment property are substantial. Mortgage interest alone is typically 60%–70% of your rental income. Combined with other deductions, most investment properties have negative taxable income even if they’re generating positive cashflow.

This is legitimate and legal—it’s why property investment is attractive tax-wise.

Keep records, work with an accountant, and claim everything you’re entitled to. The savings add up to thousands annually.
