First home buyers in NT

The NT currently has no first home buyer stamp duty concession, so first home buyers pay the same duty as everyone else. Territory grants for first home buyers are separate from duty — check the Territory Revenue Office for what’s available.

Foreign buyers

Our calculator applies no foreign purchaser duty surcharge for the NT. Confirm the current position with the Territory Revenue Office.

Registration fees and total government costs

The NT Land Titles Office charges $181 to register a transfer and $181 to register a mortgage. At $600,000 that makes total government costs of $30,062 for a home you’ll live in (duty plus both fees). See stamp duty fees vs total government costs to compare states.

When is NT stamp duty paid?

Duty is usually paid at settlement through your conveyancer.
