How Do I Keep Tax-Compliant Records as a Property Investor in Australia?
What property investors need to keep for the ATO — income, expenses, depreciation and CGT records — how long, and how it differs by ownership structure.
How do I keep tax-compliant records as a property investor?
Keep every record connected to buying, running and eventually selling the property — settlement documents, loan paperwork, rental income and expense records, a depreciation schedule, and receipts for any capital improvements — for as long as you own the property, plus at least five years after you dispose of it. That’s the ATO’s stated position specifically for property capital gains tax (CGT) records: records are kept for the full ownership period plus a minimum of five years after disposal, because most of what you file along the way eventually feeds into the capital gain or loss calculation when you sell.
If you’re weighing up property investment more broadly, recordkeeping is one of the less exciting parts of the job — but it’s the part that protects a deduction, a discount, or a cost-base calculation years after the fact, when the receipt or the schedule is the only thing standing behind the claim.
What records do you actually need to keep?
A property investor’s paper trail (digital or physical — the ATO doesn’t mandate a format) generally falls into six buckets:
| Record type | Examples | Retention benchmark |
|---|---|---|
| Purchase and settlement | Contract of sale, settlement statement, stamp duty assessment, conveyancing invoices | Whole ownership period + 5 years after sale |
| Finance | Loan contract, interest statements, refinance and discharge documents | Whole ownership period + 5 years after sale |
| Rental income and expenses | Property manager statements, rent ledgers, invoices for repairs, rates, insurance, body corporate fees | Whole ownership period + 5 years after sale |
| Depreciation | Tax depreciation schedule, invoices for depreciating assets | Whole ownership period + 5 years after sale |
| Capital improvements | Renovation contracts, building permits, receipts for capital works | Whole ownership period + 5 years after sale |
| Sale/disposal | Contract of sale, selling costs, agent and legal invoices | At least 5 years after the sale is finalised |
That single benchmark — full ownership period plus a minimum of five years after disposal — is the practical rule to apply across all six categories, since the ATO’s own guidance ties it to property CGT records specifically and almost every category above ultimately affects the CGT outcome when you sell. One extra case worth flagging: if a property was your home before it became income-producing after 20 August 1996, the ATO’s guidance says to record its market value at that point — that market value becomes a relevant figure for your eventual capital gain calculation, so it’s worth capturing (a written valuation, or at minimum a contemporaneous appraisal) at the time the property starts being rented out, not years later from memory.
What records support your rental income and deductions?
Under current law, a rental property is negatively geared when your deductible expenses — including loan interest — exceed your rental income for the year. The ATO’s position: “you may be able to claim a deduction for the full amount of rental expenses against your rental and other income (such as salary, wages or business income)… where the other income isn’t sufficient to absorb the loss you can carry it forward to the next income year.” There’s no dollar cap on that loss under current law, and no requirement that it only offset rental income — but there is no deduction without a record behind it. Our guide to cash-flow-positive vs negatively geared property covers the underlying trade-off; this article is about the paperwork that substantiates whichever position you’re in.
Practically, that means keeping:
- Property manager or agent statements showing rent received and fees deducted
- Loan statements showing interest charged for the year
- Invoices and receipts for council rates, water rates, insurance, strata/body corporate fees, and repairs
- A record distinguishing repairs (generally deductible in the year incurred) from capital improvements (depreciated over time) — the invoice description and the nature of the work both matter here
Tax outcomes depend on your circumstances — speak with a registered tax agent before acting, particularly on the repair-versus-improvement distinction, which turns on the specific work done.
Depreciation records: Division 40 and Division 43
Two separate depreciation regimes apply to a residential rental property, and each needs its own kind of record.
Division 43 (capital works) covers the building structure itself — construction costs, not separately identifiable assets. For residential rental capital works where construction commenced on or after 16 September 1987, the rate is 2.5% per year over 40 years. The record you need is evidence of the original construction cost (or a professionally prepared cost estimate where the original isn’t available).
Division 40 (plant and equipment) covers separately identifiable depreciating assets — ovens, carpets, air-conditioners and similar items — each with its own effective life. Since 9 May 2017 (specifically, assets acquired at or after 7:30pm AEST that day), a further restriction — new s40-27 of the Income Tax Assessment Act 1997, inserted by the Treasury Laws Amendment (Housing Tax Integrity) Act 2017 — generally reduces the Division 40 deduction to nil for second-hand plant and equipment in a residential rental property, for an ordinary individual landlord. A small number of entity types are excepted (corporate tax entities, most large super funds, managed investment trusts, public unit trusts) — but an SMSF is not one of them, so an SMSF-owned residential property is caught by this restriction like any other individual investor.
Division 43 building deductions aren’t affected by this restriction either way. Keeping the purchase invoice for each depreciating asset — and noting whether you were the first person to use or install it — is what lets a depreciation schedule correctly separate what’s still claimable from what isn’t. Tax outcomes depend on your circumstances — speak with a registered tax agent before acting.
What extra records does capital gains tax require?
Beyond the general categories above, CGT adds two record-keeping wrinkles specific to how you hold the property.
Co-ownership. If you own the property with someone else, your CGT share follows your ownership form. As joint tenants, you’re each treated, for CGT purposes, as owning an equal separate interest as tenants in common (two joint tenants = 50/50, four = 25% each) — this is set by statute, not by choice. As tenants in common, your share follows your actual legal percentage, which can be unequal, and each owner can deal with their share independently.
The two forms also differ on death: a tenant in common’s share becomes part of their estate, while a joint tenant’s share generally passes to the surviving joint tenant(s) by survivorship. Whichever applies to you, keep a record of your exact ownership percentage and form — it determines how much of any future capital gain or loss is yours to report.
The 12-month discount rule. An eligible Australian resident individual who has held a CGT asset for at least 12 months (excluding the day of acquisition and the day of the CGT event) can access a 50% CGT discount on the resulting gain; trusts also get 50%, and complying super funds (including SMSFs) get a one-third discount. Companies get no discount. None of that is available without a record of exactly when you acquired the asset — the settlement date on your contract of sale is the reference point, so it’s worth keeping that document accessible rather than relying on memory of “around when we bought it.” Tax outcomes depend on your circumstances — speak with a registered tax agent before acting.
Do your records differ by ownership structure?
Yes — the structure you hold an investment property in changes both the tax treatment and what you need to keep on file. This is general information, not a recommendation of one structure over another; no single ATO or Moneysmart page ranks or recommends between them, and the right structure for you depends on circumstances a registered tax agent or licensed financial adviser needs to assess.
| Structure | Tax treatment (high level) | What that means for records |
|---|---|---|
| Individual | Assessed at personal marginal rates; 50% CGT discount available at ≥12 months | Standard six categories above, kept in your own name |
| Company | Company-level tax; no general 50% CGT discount | Company accounting records, board/shareholder resolutions where relevant |
| Discretionary/family trust | Net income generally taxed in beneficiaries’ hands, per their entitlement; 50% CGT discount available | Trust deed, distribution resolutions each year, beneficiary entitlement records |
| SMSF | Concessional 15% fund tax rate; one-third CGT discount at ≥12 months; superannuation-law constraints not present in the other three | Everything above, plus SMSF-specific records below |
If you hold property through an SMSF
An SMSF-owned investment property carries extra record-keeping obligations that don’t apply to the other structures:
- A written investment strategy. Super law requires every SMSF to have one — the ATO describes it as “your plan for making, holding and realising assets”, covering risk and likely return, diversification, liquidity (how easily fund assets can be converted to cash to meet expenses and pay benefits), whether to hold insurance for members, and each member’s circumstances. There’s no prescribed format, but it’s a document the fund must have and keep current — not a one-off form filed at setup and forgotten.
- The in-house asset limit. An SMSF is restricted from holding in-house assets — broadly, loans to, investments in, or assets leased to a related party — above 5% of the fund’s total assets by market value. Records showing the fund’s relationship (or lack of one) to the parties involved in a property transaction, and that any acquisition from a related party reflected market value, matter here.
- Annual valuation and audit. SMSF trustees must value fund assets at market value each year for the fund’s financial accounts, using objective and supportable evidence — for an unlisted or illiquid asset, the ATO points to things like an independent expert valuation, a property valuation, or the price and date of a recent arm’s-length sale of a comparable interest. Every SMSF must also be audited each year by an independent, ASIC-registered SMSF auditor, and trustees need to give that auditor evidence of how each valuation was reached — which means the valuation record itself, not just the resulting number, is what you keep.
Superannuation rules are complex and penalties for breaches are significant — seek advice from a licensed financial adviser before making SMSF decisions.
Does land tax add anything to your records?
Possibly, depending on where the property is. Land tax is set by each state and territory individually — there’s no national land tax and no single comparison page, and thresholds and rates move at state budgets. What that means for your records is straightforward: keep every land tax assessment notice you receive from your state or territory revenue office, and don’t assume a rule or figure from one state applies in another — check directly with the revenue office for the state the property is in.
What’s changing from 2027 — and what should you keep now?
As at July 2026, two enacted changes are worth building into your recordkeeping now, even though neither applies yet.
Negative gearing quarantine, from the 2027-28 income year. Under law enacted by Act No. 49 of 2026, residential rental deductions that exceed residential rental income will no longer offset other income (like salary) — the excess will instead be quarantined, usable only against residential capital gains or carried forward against future residential rental income. Interests acquired before 7:30pm AEST on 12 May 2026 are grandfathered under the current rules described earlier in this article. This is a separate, later change from the CGT reform below — worth keeping distinct in your own records and reading.
CGT changes for events on or after 1 July 2027. The same Act ends the 50% CGT discount for individuals, trusts and partnerships (retained for new residential dwellings and affordable housing; super funds keep the one-third discount) and returns CPI indexation of the cost base going forward. For any property you already hold at the transition, the current default rule deems the asset sold and reacquired at market value just before 1 July 2027, becoming the new starting cost base from that point — unless a separate apportionment method, which the law allows the Minister to prescribe by legislative instrument, is made before then (as at July 2026 it hasn’t been). The practical record-keeping step now: if you hold a property you intend to keep past mid-2027, a professional valuation dated as close as possible to 30 June 2027 is worth having on file, since that value may become your new cost-base reference point.
Our guide to how capital gains tax applies to property covers the current-law mechanics this reform sits on top of. Tax outcomes depend on your circumstances — speak with a registered tax agent before acting, and revisit this section closer to 1 July 2027 as ATO guidance develops.
The bottom line
Treat “keep it for the whole time you own the property, plus at least five years after you sell” as your default for every category — purchase and settlement documents, loan records, rental income and expense evidence, your depreciation schedule, improvement receipts, and sale documents. Layer on the extras your situation adds: your exact ownership percentage and form if you co-own, a documented acquisition date to support the 12-month discount, and — if the property sits in an SMSF — your investment strategy, in-house asset records, and annual valuation and audit evidence. None of this replaces a registered tax agent’s advice for your own return, but it’s the difference between a deduction or discount you can support and one you’re hoping the ATO doesn’t ask about.
