How to Track Rental Property Tax Deductions (and What the ATO Actually Wants to See)
Most landlords claim fewer deductions than they're entitled to — not because the deductions don't exist, but because the records weren't kept. Here's the system the ATO expects and how to build it without a filing cabinet.
The ATO's starting position on rental property deductions is blunt: if you can't show a record, the deduction doesn't exist. The evidentiary standard is a written receipt dated on the day of purchase, a bank statement for direct debits, or a contractor invoice with an ABN on it. A note in your phone saying "plumber, $240" is not a receipt. A photo of a receipt is — provided the date, amount, and supplier are legible.
Borrowing costs in year one are the deduction landlords most commonly miss entirely. The stamp duty you paid on the mortgage, lender's mortgage insurance, and any application fees are collectively deductible — but spread over five years (or the loan's life if shorter), not claimed in full at settlement. Most landlords either skip them or claim the whole amount in year one, which triggers an amendment.
Depreciation versus immediate write-off is the next most common error. Items costing less than $300 can be deducted in the year of purchase. Anything above that threshold goes onto the depreciation schedule. The threshold applies per item, not per receipt — a set of blinds costing $800 cannot be split across four windows to get four $200 deductions.
Repairs versus capital improvements is the distinction that causes the most audit attention. A repair restores something to its original condition: painting the walls the same colour, replacing a broken tap washer, re-laying the same tiles after a leak. A capital improvement makes the property better than it was: adding a deck, replacing a ducted air conditioning system with a newer model, converting a carport to a garage. Repairs are deductible in the year they're incurred. Improvements are depreciated over 40 years under Division 43. The ATO looks at intent and outcome — "we were just maintaining it" is not enough on its own.
Body corporate levies (strata fees) are fully deductible in the year you pay them — the quarterly and annual levies that cover the building's day-to-day running costs. The capital works levy (the sinking fund contribution) is not. It builds reserves for future improvements, which makes it capital expenditure, not a current-year maintenance expense.
Interest apportionment catches landlords who have ever drawn on an offset account or line of credit for personal spending. The ATO expects you to apportion interest between the investment and personal portions of any mixed-use facility. If you can't trace the full loan balance back to the investment, you need to split the interest. Most landlords don't track this. Most accountants discover the problem after the return is filed.
Why the date on a receipt matters more than the amount: the ATO treats undated receipts the same as missing ones. If a contractor hands you an undated invoice, ask for a corrected one before you leave.
How a property management CSV export saves you time: a well-structured export tags every transaction by property, category, and date. Those categories — income received, interest and bank charges, management fees, council rates, water charges, land tax, insurance, repairs and maintenance, depreciation, capital works, and borrowing expenses — map directly onto the ATO's rental income and expense worksheet. An accountant who receives a clean CSV can populate the rental schedule in twenty minutes. One who receives a shoebox of receipts and a phone full of screenshots cannot.
