Why This Year’s Return Is the Quiet One

Every public conversation about Australian property tax right now is about the 2026 budget. None of it changes the 2025–26 return.

The negative gearing and CGT package announced on 12 May 2026 commences from 1 July 2027. The Australian Taxation Office’s own explainer states that “this measure is not yet law” — meaning the 2025–26 return is filed under the rules that have actually been legislated, not the rules being modelled in commentary. Source: Australian Taxation Office — Tax reform: Boosting home ownership.

The 2025–26 return — covering rental activity between 1 July 2025 and 30 June 2026 — sits entirely under the existing rules. The 50% CGT discount applies in full to any sale in this window. Negative gearing operates unchanged. The only budget-night change with current-year footprint is the start of the post-announcement acquisition clock for established residential properties — and even that does not affect what you deduct this year. It affects how losses are treated from 1 July 2027 onward on properties acquired after 12 May 2026.

So the 2025–26 return — and the 2026–27 return that follows — both run entirely under the old rules. The 2027–28 return is the first one under the split regime. For long-holders and grandfathered investors, every return from 2027–28 onward will introduce at least one new mechanic (split-CGT calculations, eligible-new-build elections, quarantined-loss rules on post-announcement acquisitions). The discipline you build over the next 45 days is exactly the discipline you need in every year after — and the two clean years you have now are the right window to build it.

The Six-Week Timeline

Pre-EOFY actions in week 6 are the only items with a hard 30 June deadline. Everything else is record-gathering that can extend into July and August, but the cost of leaving it is the same cost it has always been — missed deductions, retrospective reclassifications, and audit exposure if a query lands months later.

Week 1 — Property-Management Statement Reconciliation

For each property, request a full-year statement from your property manager covering 1 July 2025 to 30 June 2026. The statement should itemise:

• Gross rent received, per tenancy and per month
• Letting fees, management fees, advertising costs
• Repairs and maintenance the manager arranged (with separate invoices attached)
• Council rates, water rates, body corporate fees they paid on your behalf
• Any insurance premiums or strata levies paid through the manager
• Any vacancy periods, with start and end dates

Reconcile against your bank statements. Every cent the manager records as paid out should land somewhere — either as a deductible expense, as a capital improvement (still important for cost base purposes, just not immediate), or as something you paid them back for. Mismatched lines are the audit-bait the Australian Taxation Office actively flags. Source: Australian Taxation Office — Record keeping for rental properties.

For multi-property portfolios, reconcile each property separately. Do not consolidate before the categorisation pass in week 3 — the per-property detail is what matters at the schedule level.

Week 2 — Mortgage Interest and Loan-Purpose Audit

Your bank or lender should provide a loan statement showing total interest charged for the financial year on each loan secured against an investment property. Get this in writing, not from a verbal phone call.

The audit question is what the borrowed money was used for, not which property secured the loan:

• Pure investment loan — funds used entirely to acquire or improve the rental property → interest fully deductible against the rental income.
• Mixed-purpose loan — for example, a redraw used for a holiday, a car, or a renovation of your own home → interest must be apportioned. The non-investment portion is not deductible.
• Refinanced loan — the deductibility follows the use of the borrowed funds, not the security. Refinancing an investment loan does not change deductibility; refinancing a personal loan against an investment property does not make the personal-purpose interest deductible.

Mixed-purpose loans are one of the top items on the Australian Taxation Office’s current rental watchlist. If you have ever redrawn, topped up, or consolidated a loan secured against the rental, you owe yourself a loan-balance walk-through this week — by year, by transaction. The deductible portion is calculated against the original investment-purpose balance, not the current balance.

For a worked example of mixed-purpose loan apportionment, see our Australian Rental Deduction Apportionment 2026 explainer.

Week 3 — Repair Versus Improvement, Line by Line

Pull every maintenance and works invoice from the year onto one page. For each, write down:

• The date
• The amount
• A one-sentence description of the work
• The category — repair, improvement, or initial repair

The Australian Taxation Office’s definitions are mechanical and worth memorising.

The line the Australian Taxation Office cares about most is initial repair. A new investor who buys a tired property, spends the first six months fixing pre-existing damage, and then claims those fixes as immediately deductible repairs is making the single most common error on rental returns. The fix is capital regardless of how it is invoiced. Source: Australian Taxation Office — Repairs, maintenance and capital expenditure.

Worked test for any individual invoice:

1. Did the work fix a problem that existed before the most recent tenant moved in? If yes, suspect initial repair — capital.
2. Did the work materially improve the asset compared to its original state? If yes, capital improvement.
3. Did the work use materials of a notably higher standard than what was replaced? (Solid timber decking replacing pine; engineered stone replacing laminate.) If yes, capital improvement.
4. Did the work merely restore the existing standard? If yes — and not an initial repair — deductible.

Week 4 — Depreciation Schedule Review

A qualifying quantity surveyor depreciation schedule is the single document that does the most work on your return for the least ongoing effort. It separates Division 40 (plant and equipment — appliances, blinds, carpets, hot water systems) from Division 43 (capital works — the building shell, walls, roof, kitchen as fitted) and assigns a depreciation rate to each.

Three rules from the 2017 reform that still apply in 2025–26:

1. Plant and equipment in residential property acquired after 7.30pm AEST on 9 May 2017 is restricted to brand-new items installed by the current owner. Second-hand plant and equipment — items in the property when you bought it — generally cannot be claimed by individual investors or family trusts. Source: Australian Taxation Office — Residential rental properties.
2. Division 43 capital works are unaffected by the 2017 reform. Buildings constructed after 15 September 1987 attract a 2.5% per-year deduction for 40 years from construction date.
3. Capital improvements made by the current owner — kitchen, bathroom, deck — are Division 40 (the appliances and removable fittings) and Division 43 (the structural work), depending on the line item. A surveyor’s schedule allocates these correctly.

If you do not have a depreciation schedule and the property was built after 1987 (or has had significant post-2000 capital improvements), commissioning one before 30 June 2026 lets you claim a part-year deduction this year. Schedules typically cost $500–$700 and pay back in the first year. The Australian Taxation Office maintains a Depreciation and capital allowances tool for self-assessment of straightforward items, but for properties with material capital works a surveyor’s schedule is the documentary defence the office expects.

Week 5 — Apportionment Math

Three apportionment situations land on most rental schedules at some point.

Personal-use periods

If you, your family, or anyone connected to you stayed in the property without paying market-rate rent during the year, the deductions for that period are not claimable. Calculate the personal-use days as a fraction of the days the property was used or available all year:

• Personal-use days ÷ (days rented + days genuinely available for rent + personal-use days) = personal-use fraction
• Reduce every variable annual expense (interest, rates, insurance, depreciation) by that fraction

For holiday homes, the availability test is sharp: the property must be advertised at commercial rates on platforms a real holiday-let market uses, in a way that would not deter a paying guest. A property listed materially above the comparable market rate is not “genuinely available” in the Australian Taxation Office’s terms. Nor is a property that is technically listed but carries access restrictions a paying guest would refuse — guests required to provide their own linen and consumables, weekends or peak periods blocked out, the owner staying in an adjoining flat, or check-in arrangements that effectively prevent letting. A property blocked out for January and July school holidays is not “genuinely available” for those weeks. Source: Australian Taxation Office — Holiday homes.

For more depth on the short-stay specifics — including the Australian Taxation Office’s stated 2026 watchlist on holiday and short-stay properties — see our Holiday homes and short-stay rentals — Australian Taxation Office risk zones piece.

Vacancy periods

Periods when the property was genuinely available for rent but not let — actively advertised at a commercial rate, professionally managed or self-managed with documented marketing — remain deductible. Periods when the property was not available (you were renovating, you took it off the market, you used it personally) reduce the deduction.

The documentary trail is the property manager’s marketing campaign records, dated photos of the listing, and the lease-break or vacancy report.

Co-ownership

Deductions split by legal ownership share, not by who paid:

• Joint tenants — deemed equal shares; for two joint tenants, 50/50 regardless of contribution
• Tenants in common — shares as registered on title; 60/40, 75/25, 99/1 all permitted but the split is the title-registered figure

Each co-owner reports their proportional rent income and their proportional share of every expense on their own return. Source: Australian Taxation Office — Co-owners of investment properties.

The common error is the household that operates as if all the rental property paperwork is held by the higher-earning spouse, then tries to claim the deductions on that spouse’s return only. The Australian Taxation Office’s position is unambiguous: deductions follow title.

Week 6 — Pre-EOFY Actions With 30 June Deadlines

The actions that must happen before midnight on 30 June 2026 are narrower than they look. Most rental tax work — categorisation, lodgement, schedule preparation — happens after the year closes. A small set of actions move the deduction from next year into this year, and they are the genuine time-sensitive items.

Prepay deductible expenses

If you can pay an expense in June that you would otherwise pay in July, the deduction moves into the 2025–26 return — provided the prepayment is for a service period ending within 12 months and within the next income year. The Australian Taxation Office’s 12-month prepayment rule applies to individuals (non-business) on:

• Mortgage interest — only deductible as a prepayment under section 82KZM of the Income Tax Assessment Act 1936 where the loan has a fixed-interest period covering the prepayment window and the prepaid period ends within 12 months and within the next income year. Many variable-rate loans do not permit interest prepayment at all; fixed-rate loans typically allow up to 12 months but on lender-specific terms. Useful if you expect 2026–27 to be a lower-income year and 2025–26 is the high-bracket year — confirm both the lender’s prepayment mechanics and the deductibility test with your tax agent before transferring funds.
• Landlord insurance — pay the next 12 months in June
• Body corporate / strata fees — ordinary administrative levies, if your scheme allows annual prepayment. Special levies for capital works are not immediately deductible — they are added to cost base under Division 43 capital works rules and depreciated where eligible
• Pest inspections, smoke alarm services, gutter cleaning — bring forward routine items into June if you were planning them anyway

Do not prepay expenses you do not have a clear plan to incur. The Australian Taxation Office’s general anti-avoidance position is straightforward — bringing forward genuine annual expenses is fine; pre-paying speculative or non-arising costs is not deductible.

Get repairs done now if you were going to do them anyway

A roof patch in late June is a repair this year. The same patch in early July is a repair next year. If you have a legitimate repair on the list and the contractor is available, the timing decision is worth $0.30 to $0.45 of every dollar (depending on your marginal rate) of present-value benefit.

This is not an instruction to invent repairs. It is an instruction to time the ones you already need.

Commission the depreciation schedule

If you have not previously had a quantity surveyor’s schedule prepared and the property qualifies, a surveyor’s site visit and report in June lets you claim a part-year Division 43 (and any qualifying new Division 40) deduction this year. The surveyor’s fee itself is also immediately deductible.

Confirm bank balances and statements

Some lenders take five to ten business days to issue a full-year interest statement. Request it before mid-June so the document is in hand when you (or your agent) start the return after 30 June.

What’s Genuinely New This Year

Aside from the budget package — which does not affect the 2025–26 return — the changes that matter for this year’s return are quieter.

None of these are reform. They are the Australian Taxation Office continuing to operate the same rules with steadily better data-matching infrastructure.

State and Territory Items the Federal Return Does Not Cover

The federal rental schedule covers federal income tax. Three state-level items also have an EOFY rhythm and are easy to forget:

• Land tax assessments — issued annually by each state and territory revenue office. Land tax is not part of the federal return but is itself deductible against rental income in the year incurred. The notice dates differ by jurisdiction: New South Wales Revenue NSW issues assessments in early calendar year; Victoria’s State Revenue Office issues in the first quarter; Queensland Revenue Office issues mid-year. Make sure the right year’s assessment lands on the right year’s return.
• Absentee owner and foreign-ownership surcharges — Victoria, New South Wales, Queensland, South Australia, Tasmania, Western Australia, and the Australian Capital Territory each apply some form of surcharge to investors who do not meet state or territory residency or citizenship tests; definitions, thresholds, and rates vary materially between jurisdictions. These are state-set and outside the federal budget’s reach.
• Vacant residential land tax — Victoria’s vacant residential land tax expanded statewide from 1 January 2025 and assesses vacancy during the prior calendar year. The first statewide assessment, covering vacancy during the 2025 calendar year, was issued in early 2026. The deduction belongs in the financial year the notice falls due, not the calendar year of vacancy.

Record-Keeping Standard the Australian Taxation Office Expects

The Australian Taxation Office’s record-keeping rule for rental properties is a five-year minimum from the date of lodgement of the return that used the record. For records relevant to the cost base of an asset still held (purchase contract, capital improvement invoices, stamp duty receipt), the period extends to five years after the eventual sale.

Documents the office expects to be able to produce on request:

• Purchase contract and settlement statement
• Stamp duty receipt
• Annual property-manager statements (per property, per year)
• Annual mortgage interest statements from the lender
• Repair and maintenance invoices, separated from capital improvement invoices
• Council rates, water rates, strata or body corporate notices
• Insurance certificates of currency and premium notices
• Depreciation schedule from a quantity surveyor (if applicable)
• Travel records (only if claiming under the very narrow rental-business carve-out)
• Co-ownership documentation, where applicable

Across two or three properties, this is several hundred documents per year. AI document management prepares cited categorisation workups (repair vs improvement, deductible vs cost base, per-property allocation) for the return in October and the post-2027 split-treatment regime that follows.

The Short Version

1. Forty-five days separate today from 30 June 2026. Self-lodgers file by 31 October 2026; tax-agent clients typically have until 15 May 2027.
2. The 2026 budget package does not change the 2025–26 return. Negative gearing and CGT reform commence from 1 July 2027 — meaning both the 2025–26 and 2026–27 returns will be filed under the current rules, and the 2027–28 return is the first under the split regime.
3. Interest, repairs, and apportionment are the three lines the Australian Taxation Office watches hardest. A 30-minute loan-statement audit, a per-invoice repair-versus-improvement pass, and a personal-use-period apportionment are the three highest-value pieces of EOFY prep.
4. Initial repairs are capital, not deductible — even when the work looks like a repair. New-investor returns mis-classify these constantly.
5. Travel to inspect residential investment property is not deductible for individuals, family trusts, or partnerships and has not been since 1 July 2017.
6. Second-hand plant and equipment is not depreciable for residential property acquired after 9 May 2017. Division 43 capital works continue unaffected.
7. Co-owners split deductions by title share, not by who paid. Joint tenants are 50/50 deemed.
8. Pre-EOFY actions with a 30 June deadline: prepay deductible insurance, body corporate, and routine maintenance you were going to incur anyway; complete repairs already on your list; commission a depreciation schedule if you do not have one.
9. Five years minimum of record retention from lodgement date — longer for cost-base records on property still held.
10. Build the discipline this year that the post-1-July-2027 regime requires. The split-CGT and quarantined-loss rules amplify the value of clean records — the work you put in now compounds.
