You can claim any deductible expense your rental property incurs — but only if you can prove it. The ATO can request supporting records years after the event, and if you can’t produce them, the deduction is disallowed. Good record-keeping is not bureaucratic box-ticking: it is the foundation of every claim you make. This checklist covers every category of records you need to keep, how long to keep them, and what the ATO is looking for.
The retention rules
Standard deductions: Keep records for 5 years from the date you lodge the tax return in which you claimed the deduction.
Capital gains tax records: CGT is calculated on the difference between what you paid (adjusted cost base) and what you received on sale. The cost base includes your original purchase price, stamp duty, legal fees, and the cost of any capital improvements. You must keep all of these records for the entire ownership period plus 5 years after the year you lodge the return reporting the capital gain.
This means if you buy in 2026 and sell in 2041, and lodge the return reporting the gain in 2042, you need to keep your purchase records until 2047. The 5-year clock resets on the sale return, not the purchase.
ATO data matching: you will be checked
Before reviewing the checklist, understand how the ATO verifies your return. The ATO’s data matching program automatically cross-checks:
- Rental income declared by property managers against your return
- Loan interest reported by banks and lenders
- Land title records showing ownership, purchase price, and transfer date
- Short-term rental platforms (Airbnb and others provide data directly to the ATO)
- Foreign investment review records for purchases by foreign residents
If you under-declare rental income or over-claim deductions, the ATO is likely to detect it. The penalties for incorrect claims range from 25% (for taking a “reasonably arguable” position that turns out to be wrong) up to 75% of the shortfall for deliberate evasion, plus interest.
Records checklist by category
| Category | What to keep | Retention period |
|---|---|---|
| Purchase | Contract of sale, settlement statement, stamp duty receipt, legal invoices, building and pest inspection reports | Ownership + 5 years after CGT return |
| Loan and finance | Annual loan statements, interest certificates from lender, loan agreement and mortgage documents, records of any redraws (amount, date, purpose) | 5 years from lodgement |
| Rental income | Property manager monthly and annual statements, direct tenant receipts (if self-managed), bond lodgement receipts | 5 years from lodgement |
| Recurring expenses | Council rate notices, water rate notices, insurance policy schedules and premium receipts, strata/body corporate levy notices | 5 years from lodgement |
| Repairs and maintenance | Receipts and invoices for every repair, description of what was repaired and why (distinguish repairs from improvements) | 5 years from lodgement |
| Capital improvements | Builder contracts and invoices, photos before and after works, council approvals, description of structural changes | Ownership + 5 years after CGT return |
| Depreciation | Quantity surveyor report, ATO depreciating asset schedules, purchase receipts for all new plant and equipment you install | Ownership + 5 years after CGT return |
| Borrowing costs | Loan establishment fee invoices, LMI certificate, mortgage registration fee receipts | Ownership + 5 years (affect cost base on sale) |
| Property management | Management agreement, all agency invoices and fee statements, letting fee invoices | 5 years from lodgement |
| Private use records | Usage diary for holiday homes (nights rented, nights personal, nights vacant but available) | 5 years from lodgement |
Repairs vs improvements: a critical distinction
The ATO distinguishes between a repair (restoring something to its original condition) and a capital improvement (making it better than it was). Repairs are deductible in full in the year you pay for them. Capital improvements are depreciated over time under Division 43 or Division 40.
If you replace a broken fence with the same style of fence, that’s a repair. If you replace a timber fence with a Colorbond fence, that’s an improvement. Keep enough documentation — invoices, photos, description of the defect that prompted the work — to demonstrate which category applies.
Digital records
The ATO accepts digital copies of documents. You can photograph paper receipts on your phone, scan invoices, and download PDF statements from your bank and agent. As long as the image is clear, legible, and includes all relevant details (date, supplier, amount, description), it satisfies the record-keeping requirements.
A few practical approaches:
- Set up a dedicated folder in cloud storage (Google Drive, Dropbox, iCloud) named by property and year.
- Forward email receipts and invoices to a dedicated email folder.
- Download annual loan interest certificates from your lender’s portal each July.
- Ask your property manager for an annual income and expense summary at tax time — most will provide this automatically.
What happens if you can’t produce records
If the ATO audits your return and you can’t substantiate a claim, the deduction is disallowed. For a $5,000 deduction at a 37% marginal rate, that’s a $1,850 tax liability — plus interest charges back to the original due date, and potentially a penalty on top.
For CGT purposes, if you can’t prove the cost base, the ATO may assess the gain using a lower (or no) cost base, significantly increasing your CGT liability. This is particularly costly for properties held for decades where records have been lost.
Sold the property? Your obligations don’t end
On settlement, collect and store:
- Contract of sale and settlement statement from sale
- Agent’s selling commission invoice
- Legal fees for conveyancing
- Any costs of preparing the property for sale (advertising, styling)
These costs adjust your capital proceeds for CGT and should be kept for 5 years after the return reporting the gain is lodged.
If the property was your main residence for part of the ownership period, you’ll need records supporting the periods of residence vs rental — including lease agreements showing when tenants moved in, and documentation of when you moved out.
Key takeaways
- Keep purchase and improvement records for the entire ownership period plus 5 years after the CGT return.
- Keep all other records for 5 years from the date you lodge the relevant return.
- The ATO data-matches rental income, loan interest, and title records automatically.
- Digital copies are acceptable — photograph receipts, download statements, maintain a cloud folder per property per year.
- Document the distinction between repairs and capital improvements at the time of the work, not years later.
- A usage diary is essential for any property with private-use periods.
