How long does the ATO require property investors to keep records?

The ATO's general rule is 5 years from the date you lodge your tax return. Records relating to property purchase, capital improvements and eventual sale (the CGT records) need to be kept for 5 years after the property is sold — which can be 20+ years from when the record was created. The full ATO guidance is on their Records for rental properties and holiday homes page.

Does the ATO accept digital records, or do I need to keep paper?

The ATO accepts records in electronic form provided they are a true and clear reproduction of the original. A photo, scan or PDF of a paper receipt is acceptable as long as it's readable and shows the transaction details. The original paper isn't required to be kept once you have a clean digital copy that's backed up.

What records does the ATO actually expect me to keep for a rental property?

Per the ATO's rental property record-keeping guidance: records of rental income received (lease agreements, rental statements, bank deposits), records of all rental expenses (invoices, receipts, bank statements, agent statements), records of any depreciating assets (purchase invoices, dates), records of capital improvements and capital works (contracts, invoices, before/after photos), loan documents and statements, and records of the property purchase and (eventually) sale.

How does the ATO check whether my records are adequate?

Through data-matching and audits. The ATO collects data from property managers, banks, landlord insurance providers, sharing economy platforms (e.g. Airbnb), and rental bond authorities. When their data shows income or expenses that don't match what you've declared, they may issue a query asking you to substantiate. Good records mean the answer is a 10-minute email; poor records mean the answer is a several-week reconstruction project.

I've been investing for years and my records are messy — what should I do?

Start with the current financial year and get the system right going forward, then work backwards property by property. Prioritise records you'll need within the next 12 months (current year tax return, anything you might sell soon, anything with active depreciation claims). Older records that fall outside the 5-year retention window for income-and-expenses (but still inside the longer window for CGT) need to be assessed by your accountant.

Can my accountant access my records directly?

Yes, and it makes the year-end process significantly faster. If your records are in a cloud accounting tool, you can grant your accountant access (typically read-only). For paper-based or local-file records, your accountant will ask for them at the start of the engagement — sending one large folder is much easier on both sides than answering ad-hoc questions through the year.

ATO record keeping for property investors: what you need to keep, for how long, and why

The ATO requires property investors to keep records that substantiate every income and expense item on the tax return. The rules themselves are clear and published on ato.gov.au — most of what people get wrong isn't the rules, it's the workflow that keeps records adequate without burning weekends. This article describes what the ATO wants, sourced directly from their guidance, and what a workable system looks like.

This is a summary of the ATO's published record-keeping requirements with links to the source pages. It is not tax advice — the interpretation of whether a specific record adequately substantiates a specific deduction in your circumstances is something to confirm with a registered tax agent.

What the ATO actually wants you to keep

Definition

Record-keeping (rental property)

The set of documents that supports every income and expense figure on your tax return for an investment property — sourced, dated, traceable to a specific property, and retained for the period the ATO requires.

The ATO's official guidance for rental property records lists the categories of records investors are expected to maintain. Summarised:

1. Income records

Lease and tenancy agreements
Rental statements from the property manager (periodic + annual)
Bank statements showing rent deposits
Records of rental bond receipts and refunds
Insurance recoveries (if a claim resulted in payment to you)
Records of any other rental-related income (e.g. parking, storage)

2. Expense records

Invoices and receipts for all rental expenses (advertising, repairs, maintenance, cleaning, gardening, pest control, etc.)
Property manager statements showing fees and disbursements
Council rates and water bills
Strata or body corporate fees
Insurance premiums (building, landlord)
Land tax assessments
Loan documents and interest statements

3. Capital records

Contract of purchase and conveyancing documents
Borrowing expenses (loan establishment fees, lender's mortgage insurance, etc.)
Stamp duty receipts
Capital improvements (renovations, structural additions) — including the contracts, invoices, and before/after photos
Records of depreciating assets — purchase date, cost, supplier, description
Quantity surveyor depreciation schedule if you have one
Eventual contract of sale and selling costs

Note

The ATO specifically suggests taking before-and-after photos of any renovation work — these are valuable evidence both for substantiating the work and for assessing whether something is a repair (deductible) or a capital improvement (depreciable / CGT-relevant). The classification of any specific item is a tax-treatment question for your accountant.

How long records must be kept

Two different retention periods apply depending on what the record relates to:

General income and expense records: 5 years from the date you lodge your tax return. This covers most operating records — rental statements, repair invoices, council rates, agency fees.
Capital records: until 5 years after the property is sold (technically, 5 years after the CGT event). This covers the purchase contract, capital improvements, depreciating assets and anything else that feeds into the cost base for capital gains tax. In practice, this means keeping those records as long as you own the property.

The two retention rules combined mean some records (the operating ones) can be safely retired after 5 years, while others (the capital ones) need to be kept for the entire holding period of the property plus 5 years. A common mistake is treating all records under the shorter rule and discarding capital records too early — the only way to fix that gap when you sell is to reconstruct from scratch, which is often impossible.

Why this matters: the ATO is data-matching

The ATO has expanded its data-matching programs significantly. As at 2026, the ATO collects data from:

Property managers and real estate agents (rental income, fees, expenses)
Banks and lenders (loan balances, interest paid)
Landlord insurance providers (insurance claims and rebates)
Sharing economy platforms (Airbnb, Stayz, etc.)
State and territory rental bond authorities
Land title and revenue offices (transfer data, land tax)
Utility providers and councils (for property identification)

What this means in practice: if you under-report rental income or claim deductions that don't match the third-party data they've collected, the discrepancy surfaces in their system. The first contact is usually a polite request to substantiate or clarify. Investors with complete records resolve these quickly; investors with gaps either spend weeks reconstructing or end up amending returns.

Digital records — what the ATO accepts

The ATO accepts records in electronic form provided they are:

A true and clear reproduction of the original. A readable photo or scan is acceptable. A blurry photo where you can't read the amount is not.
Capable of being produced in English when requested. If your supplier's invoice is in a non-English language, retain a translation.
Stored securely. The ATO doesn't prescribe specific software but expects records to be retrievable when requested.

In practice: photographs of receipts (JPG/PNG), PDFs of emailed invoices, and exports from accounting software all qualify. Backups across two locations (cloud + local, or two cloud services) are the prudent minimum given the multi-year retention requirement.

What a workable system looks like

The records the ATO wants are easier to maintain if the system has three properties:

Capture at the point of expense, not at year end. The 24-hour rule (photo or email-forward within a day) is far less work than a year-end reconstruction.
One organising hierarchy: property → financial year → category. Search by property is the most common query; everything else follows from there.
Automatic backup. Multi-year retention without backup is a single hard-drive failure away from a serious problem.

Our companion article on how to organise property investment receipts walks through the day-to-day workflow: folder structure, filename conventions, what context to capture beyond the receipt itself, and how to handle paper-only edge cases.

What to do this week

Find your most recent property purchase or sale contract and confirm it's in a backed-up location. These are the records most commonly lost and hardest to reconstruct.
List your active depreciating assets per property. If you don't have purchase invoices for the major items (appliances, air-conditioners, hot water systems), see if you can recover them via supplier records before they age out.
Confirm you have a copy of every property's most recent loan statement. Interest paid is one of the largest deductions and one of the most commonly cross-checked against lender data.
If you use a property manager, request the most recent annual rental summary in writing. Bank statements are not a substitute for the agent's annual summary.
For everything else: start the system fresh from the current FY going forward. Trying to fix several years of historical mess simultaneously usually means fixing none of it.

When to involve your accountant

Record-keeping is the bookkeeping side. Most of the questions investors actually have ("is this deductible?", "is this a repair or a capital improvement?", "how do I claim depreciation on this?", "does my structure affect this?") are tax-treatment questions — those are your accountant's domain. Good records make the accountant cheaper because their time is spent on analysis rather than reconstruction.

Some specific situations where a conversation is worth booking:

You're about to undertake a major capital improvement (renovation, structural change, addition)
You're considering selling a property within the next 12 months
Your property's usage is changing (e.g. moving from long-term rental to Airbnb, or vice versa)
You're unsure how to treat a specific expense that doesn't fit the obvious categories
The ATO has contacted you with a query

If you'd rather not run the system manually

Property bookkeeping software automates the capture, filing, and matching steps. It doesn't replace your accountant — the tax-treatment calls still need a professional — but it does mean the underlying records are clean when the calls need to be made.

PlotBot is built for AU property investors specifically; you forward receipts and invoices to a dedicated address and the AI files them under the right property with the right category.
