NSW Rental Bond Tax Deduction: How Landlords Report Bond Money to the ATO

Bond Money in Trust Is Not Income

When a rental bond is lodged with NSW Fair Trading, it sits in trust with the Rental Bond Board. While the bond is held — whether that's six months or six years — it is not assessable income for the landlord. You don't declare it on your tax return, and you can't deduct expenses against it. The money isn't yours; it's held in trust as security for the tenancy.

This stays true regardless of the amount. A $2,400 bond sitting with Fair Trading for five years never touches your income tax return during that period.

When Retained Bond Becomes Assessable Income

The tax position changes the moment you keep part or all of the bond at the end of a tenancy. Under ATO rules, any portion of the rental bond retained by the landlord — whether for unpaid rent, water charges, cleaning costs, or property damage — must be declared as assessable rental income in the financial year you become entitled to keep it.

"Entitled to keep it" means the point at which the bond is released to you, either by mutual agreement through Rental Bonds Online (RBO) or by NCAT order.

If a tenancy ends in March 2027 and the bond refund (with $800 retained by the landlord for damage) is processed in April 2027, that $800 is assessable income in the 2026–27 financial year.

Deducting Repair Expenses

The flip side of declaring retained bond money as income is that the expenses it pays for are deductible. If you keep $800 from the bond to repair tenant damage, and the repair costs $800, you declare $800 in income and claim $800 as a rental expense — net tax impact is nil.

The critical point: you cannot claim repair expenses funded by bond money without also declaring the retained bond as income. The ATO's position is clear — if you deduct the repair cost, you must declare the matching bond income. Claiming expenses while failing to declare the corresponding income is an error that attracts audit attention.

What's Deductible and What Isn't

Bond-funded expenses follow the same deductibility rules as any other rental expense:

• Repairs and maintenance to restore the property to its condition at the start of the tenancy — deductible in the year incurred.
• Capital improvements that go beyond restoration (upgrading an old carpet to a significantly better one, replacing a basic fixture with a premium alternative) — not immediately deductible; added to the property's cost base for capital gains purposes, or depreciated over the effective life.
• Cleaning costs to return the property to a tenantable condition — deductible.
• Unpaid rent that the bond covers — simply declared as rental income (you were already entitled to the rent; the bond just funded it).

Practical Examples

Full refund to tenant. Bond of $2,400 refunded in full. No assessable income, no deductions related to the bond. The bond was held in trust and returned — it never became the landlord's money.

Partial retention for damage. Bond of $2,400, landlord retains $600 for carpet repair after tenant damage. Declare $600 as assessable rental income. Claim the $600 carpet repair as a deductible expense. Net tax effect: zero, assuming the repair cost matches the retention.

Full retention for unpaid rent. Bond of $2,400, tenant owed $2,400 in rent arrears. Declare $2,400 as assessable rental income (it's rent, received via the bond). You would have declared this rent as income anyway had the tenant paid it directly.

Record Keeping

Keep the RBO refund confirmation, the agreed or ordered bond split, and all repair invoices or quotes for at least five years (the ATO's standard retention period for rental property records). If the bond claim went through NCAT, keep the Tribunal's order as well — it documents exactly what you were entitled to retain and why.
