Rental Property Records for Business Owners

Plenty of business owners run tidy books for the business and a shoebox for the rental property. The business has software and a bookkeeper; the property has a pile of agent statements, a loan redrawn a few times, and a renovation nobody kept the invoices for. The property deserves the same discipline — the records affect every year you own it and, most expensively, the year you sell it.

Rental income means all of it

Agent statements capture the rent the agent collects, but rental income is generally broader: rent paid directly to you, insurance payouts for lost rent, bond money retained, and tenant reimbursements all generally count. Keep every agent statement, and note anything that arrived outside the agent — the annual statement alone does not always tell the whole story.

Loan interest — only the property's share

Interest is usually the largest expense, and it is also where records most often fail. The general principle is that interest is claimable to the extent the borrowed money was used for the income-producing property. Redraw from the investment loan to pay for a family holiday or a car, and the loan becomes mixed — from that point on, the interest generally needs to be apportioned, and the calculation depends on the history of every redraw and repayment. Keep loan statements for the full life of the loan, and think carefully before redrawing from an investment loan for private purposes at all.

Repairs versus capital improvements

Fixing something back to the condition it was in generally counts as a repair, deductible in the year it is done. Improving beyond the original condition, replacing an entire structure, or fixing defects that existed at purchase generally counts as capital, claimed over time or added to the cost base. The line can be genuinely grey, and invoice wording matters — a document that just says renovation works invites the least favourable reading. Ask the tradesperson to describe what was actually done.

A depreciation schedule usually earns its fee

A depreciation schedule prepared by a quantity surveyor sets out what can be claimed each year for the building and its fixtures — often claims an owner would never calculate alone, and the schedule lasts for many years once prepared. Whether it is worthwhile depends on the property's age and history, but it is a question worth asking once, deliberately, rather than never.

The records you will need when you sell

Capital gains tax is where decades of record keeping settle up. The cost base is generally built from the purchase contract, stamp duty, legal fees on the way in and out, capital improvements over the whole ownership period, and selling costs — and every element needs a document behind it. A CGT discount may be available where the property has been held for more than 12 months, but eligibility and the calculation depend on your circumstances, so treat that as a question for advice, not an assumption. Records should be kept for the whole ownership period and for a further period after the sale.

What we commonly see go wrong

• Private redraws from the investment loan, turning a clean interest claim into a contamination puzzle.
• A new kitchen claimed as repairs because the invoice said maintenance works.
• Agent statements missing for the early years of ownership after changing agents.
• No depreciation schedule ever prepared, and no one able to say what has been missed.
• A cost base reconstructed from memory at sale time, years after the receipts went missing.

A worked example

As an illustration: an owner sells a rental after fifteen years. Early in the ownership there was a significant renovation — new bathroom, rewiring, a deck — but the invoices are long gone and the builder has retired. Those costs belonged in the cost base, and without documents they are difficult to include, so the taxable gain is calculated as larger than it truly was. The renovation was real; the evidence was not kept. A single folder maintained from settlement day is all it would have taken.

When to get help

If your investment loan has been redrawn and you are not sure what is claimable, if a large renovation is planned and you want the repairs-versus-capital question answered before the invoices are written, or if a sale is on the horizon and the records are thin, raise it early. Untangling a mixed loan or reconstructing a cost base is possible, but it is slower and less certain than keeping the records was.

Is repainting and fixing a rental between tenants a repair or an improvement?

Restoring the property to the condition it was in generally leans towards a repair, while upgrading beyond that generally leans towards capital. The answer depends on exactly what was done, and initial repairs on a newly purchased property are generally treated as capital — worth confirming for your situation before claiming.

Is a quantity surveyor's depreciation schedule worth paying for?

Often, yes — it identifies annual claims many owners would otherwise miss and lasts for many years once prepared. Whether it pays for itself depends on the property's age and construction history, so ask the question for your specific property rather than assuming either way.

How long should I keep rental property records?

For the entire period you own the property, plus a further period after you sell — the cost base for capital gains tax is built from documents that may be decades old by the time they are needed. Digitise them early; paper from settlement day rarely survives to sale day.
