ACT505 Chap.3 Property Tax Net Assessable Value
Property Tax Net Assessable Value
Use the waterfall order
Build assessable value from consideration for the right to use the property. Deduct accepted irrecoverable consideration, then owner-paid rates, then calculate the 20% statutory deduction from the remaining balance.
The result is net assessable value, to which the standard rate is applied.
Keep premium and bad-rent ledgers
A premium covering more than one year is spread over the lease period or 36 months, whichever is shorter, so the spreading period is always ≤ 36 months. A receivable does not disappear merely because cash is late; it needs the separate irrecoverability test.
If an amount previously deducted is recovered, add it to assessable value in the recovery year. These ledgers make reversals visible.
Read the tenancy obligations
Rent, a lump-sum premium and a tenant payment made for the owner's benefit can affect consideration, but the label on a cash flow is not enough.
Record who is contractually responsible for management fees, rates and repairs, who pays the supplier and whether money passes through the owner. This fact note supports both inclusion and deduction decisions.
Show every base explicitly
Write assessable value before deductions, the balance after bad rent, the balance after owner-paid rates, the statutory deduction and NAV.
A bracket around the post-rates balance makes the 20% base unmistakable. The standard rate then applies to NAV, not to rent, gross consideration or the balance before the statutory deduction.
Control reversals across years
An irrecoverable amount may relate to rent previously assessed, may create a carry-back where the current property base is insufficient, and may later be recovered.
A ledger with original year, deduction year, amount and recovery year preserves the sequence. Never offset a recovery against fresh bad rent without showing both movements.

Property Tax Net Assessable Value FAQ
What is the correct property-tax deduction order?
Start with assessable value, deduct irrecoverable consideration, deduct owner-paid rates, then apply the 20% statutory deduction. The resulting NAV is multiplied by the standard rate. Keep each step on its own line and show the subtotal before applying the percentage. Check that any rates deduction reflects the facts about who paid it, and do not insert general repair or financing costs into this compact statutory route.
A reverse bridge from the final NAV to assessable value catches a deduction used twice or taken in the wrong order.
How is a premium allocated across years?
Spread it in equal monthly amounts over the lease period or 36 months, whichever is shorter. Place only the months falling in the current assessment year into assessable value.
Can actual repairs be deducted as another property expense?
The captured property-tax notes state that actual repairs and outgoings are not separately deducted in the NAV waterfall. The statutory deduction supplies the prescribed allowance after earlier deductions.
Exam move
Rebuild the waterfall from memory until every deduction has a fixed position. For each practice case, maintain a one-line premium schedule and bad-rent schedule beside the main NAV computation. Recompute the answer vertically and check the base of the 20% deduction before applying the standard rate. Add a contract column showing who bears rates, management fees and repairs.
Once the result is complete, test one changed fact, such as tenant-paid rates or a later recovery, and identify the exact line that changes. This trains the structure rather than one set of numbers.
