NT Bond Deduction Rules — What Can a Landlord Claim?
You cannot deduct from a rental bond in the Northern Territory just because the property looks worse than when the tenant moved in. The Residential Tenancies Act 1999 sets out specific grounds for retaining a bond, and NTCAT decides disputed claims.
The Permitted Deduction Categories
Section 112(3) of the Act lists what a landlord can lawfully retain from a security deposit:
- Rent arrears — outstanding rent owed up to the date the tenant gave vacant possession.
- Property damage — physical damage caused by the tenant's breach, negligence, or intentional conduct. This excludes fair wear and tear.
- Cleaning costs — what it takes to return the property to a reasonably clean condition, measured against the entry condition report.
- Lost or damaged ancillary property — keys, access fobs, remotes, landlord-owned furniture or fittings listed on the ingoing inventory.
- Unpaid utilities — water, gas, or electricity charges legally payable by the tenant under the lease.
- Locks changed without consent — the cost to replace locks the tenant altered, removed, or added without your consent.
- Amounts payable under Section 121 — compensation for loss or expense, plus rent for the period a tenant remains in possession after they were required to hand over vacant possession.
- Unpaid Tribunal orders — money the Tribunal ordered the tenant to pay but the tenant has not paid.
These are the Section 112(3) grounds when a tenant gives up vacant possession. If the tenant apparently abandoned the premises, Section 112(6)–(8) separately allows a temporary hold for lost rent and costs of securing new tenants, but a compensation claim must be made as soon as practicable after the loss can be calculated and within three months after the apparent abandonment.
You cannot deduct for "general wear," inconvenience, or the time you spent managing the tenancy.
Fair Wear and Tear vs Damage
This distinction decides most bond disputes. Fair wear and tear is deterioration from normal, reasonable use over time — the Act makes the landlord responsible for it. Damage is something the tenant caused through negligence or misuse.
Some examples from NTCAT practice:
| Item | Fair wear and tear | Tenant damage |
|---|---|---|
| Carpet | Fading, scuffing in high-traffic areas | Deep gouges, iron burns, uncleaned pet stains |
| Walls | Minor paint flaking, hairline settlement cracks | Holes punched in plasterboard, unapproved anchor holes |
| Flyscreens | Wear from sunlight and age | Tears from pet claws |
| Plumbing | Minor water scale from Darwin's hard water | Cracked basins or chipped bowls from impact |
If you cannot point to a specific act or omission by the tenant that caused the deterioration, it is almost certainly fair wear and tear.
The Depreciation Rule
Section 112(3)(a) allows only so much of the deposit as is necessary to make good tenant-caused damage, excluding reasonable wear and tear. The Act does not set an ATO-based depreciation formula. A remaining-value estimate can help show what is necessary; the formula below is one calculation using age and useful life:
Estimated remaining value = Replacement cost × (1 − Age ÷ Useful life)
For a $2,000 carpet that is seven years into a ten-year life, the estimated remaining value is: $2,000 × (1 − 7/10) = $600.
Claiming the full $2,000 is betterment — improving the property at the tenant's expense. In this example, the formula gives a $600 remaining-value estimate; the Tribunal determines the amount supported by the evidence.

The Evidence Standard
To retain any part of the bond, you must give the tenant written notice within seven business days of vacant possession and attach the statutory declaration and supporting documents required by Section 112(5). For damage or cleaning claims, attach receipts, invoices, or other documents showing the amount needed to make good the damage or clean. For damage, cleaning, or lost-property claims, Section 112(4) also requires a condition report accepted under Part 5 and an outgoing report given to the tenant under Section 110.
The declaration must attest that retention is required for the stated purpose and that the attached receipts, invoices, or other documents relate to the claim.
