Rental property is the investment class that generates the most bookkeeping queries from individual clients and family trusts. The rules are detailed — the distinction between repairs and improvements trips up even experienced practitioners — and the ATO's data-matching capabilities mean errors in rental schedules are increasingly detected. Bookkeepers who understand the rules thoroughly add real value in this space.
Individual vs. Trust Ownership — Structural Impact
Individual ownership allows negative gearing: net rental losses offset other assessable income (salary, business income) in the same year. This is the primary tax driver for many residential investors.
Discretionary trust ownership does not allow individual beneficiaries to access negative gearing. Trust losses are quarantined in the trust under the trust loss provisions (ITAA 1936 Div 266) and cannot be distributed to beneficiaries to offset personal income. Many clients incorrectly assume a family trust delivers the same negative gearing benefit as individual ownership — it does not.
Company ownership similarly quarantines losses within the entity. However, companies paying the 25% rate may benefit where the property is positively geared and the investor's marginal rate exceeds 25%.
Bookkeepers should flag the structural question to the tax agent early — the bookkeeping flows differently depending on whether the property is owned individually, by a trust, or by a company.
Deductible Expenditure — Immediate vs. Capital
The most litigated area in rental property taxation is whether expenditure is:
- Immediately deductible under ITAA 1997 s 8-1 (repair or maintenance), or
- Capital expenditure to be depreciated (improvement or initial repair)
Immediately deductible repairs: Restoring an asset to its original condition without improving it. Repainting faded walls, replacing broken tiles with like-for-like tiles, fixing a leaking pipe.
Capital improvements (not immediately deductible): Replacing a worn-out carpet with superior flooring, extending the kitchen, adding an ensuite. These are added to the cost base and depreciated.
Initial repairs trap: Expenditure to fix defects existing at the time of purchase is not deductible as a repair — it is capital, even if the work is cosmetic. The ATO's TR 97/23 is the key ruling. A bookkeeper who deducts initial repairs is creating a position the ATO routinely challenges.
Div 40 — Plant and Equipment Depreciation
Division 40 covers depreciable plant and equipment: carpets, blinds, dishwashers, air conditioning units, hot water systems, ceiling fans.
From 1 July 2017, second-hand residential rental properties no longer allow Div 40 depreciation claims for assets that were not new when acquired (Treasury Laws Amendment (Housing Tax Integrity) Act 2017). Brand new properties still allow full Div 40 depreciation. Commercial properties are unaffected.
A quantity surveyor's depreciation schedule is the standard tool for identifying Div 40 assets and their opening values. The schedule should separate Div 40 from Div 43 items.
Div 43 — Capital Works Depreciation
Division 43 covers the structural elements of the building: concrete, brickwork, roofing, plumbing (not fixtures), electrical wiring, fixed tiles, built-in cabinetry.
The deduction rate is 2.5% per annum on the construction cost (not the purchase price), over 40 years, available from the date construction is completed. For properties built before 18 July 1985, no Div 43 deduction is available.
Estimating Div 43 when the original construction cost is unknown: a quantity surveyor estimates it. The cost is a deductible expense.
Div 43 deduction = Original construction cost × 2.5%
Example: $400,000 construction cost × 2.5% = $10,000 per annum
Interest Deductibility on Mixed-Purpose Loans
Interest on borrowings used to fund the rental property acquisition is deductible against rental income. The key principle is use of funds, not security: a loan secured against one property but used to purchase another is deductible against the income from the asset funded.
Where a line of credit or offset account is used for both investment and private purposes, interest must be apportioned. The ATO's TR 2000/2 provides guidance. Common errors:
- Deducting 100% of interest on a loan that funded private redraw
- Not tracing mixed-use drawings correctly
Bookkeepers should work with clients to maintain a loan purpose register and avoid contaminating an investment loan with private expenses.
Holiday Homes — Apportioning Expenses for Mixed Use
A property used both as a holiday home (private use) and as a short-term rental (income-producing) requires expense apportionment. The ATO's IT 2167 (and more recently PCG 2021/3 on short-term rentals) requires expenses to be apportioned on a reasonable basis — typically days available for rent vs. total days in the year.
Example: Property available for rent 200 days, used privately 30 days, vacant but genuinely available 135 days.
- Deductible percentage: 200/365 = 54.8%
- Mortgage interest $24,000 × 54.8% = $13,152 deductible
Periods when the property is held for use by the owner or family — even if not physically occupied — are private use days. Weeks blocked out at peak holiday periods that coincidentally go unrented are often treated by the ATO as private use.
Practical Bookkeeping for a Rental Property Client
A clean rental property schedule requires:
- Separate bank account (ideal) or clear coding of all rental-related transactions
- Rental income reconciled to the property manager's monthly statements
- Deductible expenses coded by category: interest, rates, insurance, repairs, property management fees, Div 43, Div 40
- Depreciation schedule updated annually by the quantity surveyor or depreciation software
- Capital improvements tracked separately for CGT cost base purposes
ReconLink's coding rules make it straightforward to set up a rental client with automatic coding of recurring expenses (council rates, insurance, management fees) so the bookkeeper spends time on exceptions rather than routine transactions.
