Before relying on the estimate
Questions this calculator cannot decide alone.
Does an outside result mean the sale is tax-free?+
No. Intention, dealer, developer, builder and subdivision rules can still make a sale taxable outside the bright-line period.
Which purchase date should I use?+
A standard purchase generally starts on the LINZ title-transfer date. Off-the-plan purchases, subdivisions, co-ownership and rollover relief can use different dates.
Which sale date should I use?+
A standard sale generally ends when the binding sale and purchase agreement is entered into, not at settlement.
