Stamp Duty vs Land Tax Calculator — Australia
Should you pay stamp duty upfront or opt into annual property tax? Calculate your break-even year, cash flow impact, and long-term cost under the NSW First Home Buyer Choice scheme. AUD.
The break-even year is when cumulative annual property tax equals the one-time stamp duty. Hold less than this: property tax wins. Hold more: stamp duty was the better choice.
| Year | Cumulative Land Tax | Stamp Duty | Better Choice |
|---|---|---|---|
| Year 1 | A$1,360 | A$0 | Stamp Duty |
| Year 2 | A$2,720 | A$0 | Stamp Duty |
| Year 3 | A$4,080 | A$0 | Stamp Duty |
| Year 4 | A$5,440 | A$0 | Stamp Duty |
| Year 5 | A$6,800 | A$0 | Stamp Duty |
Land tax rate fixed at current rate. In reality, land tax is reassessed annually and increases with property value growth.
NSW First Home Buyer Choice: from January 2023, eligible first home buyers on properties up to $1.5M can opt into annual property tax instead of stamp duty.
- Australian citizen or permanent resident
- At least one buyer must be 18 or older
- Never owned property in Australia previously
- Purchase price up to $1,500,000
- Must move in within 12 months and live there for at least 6 months
- Owner-occupied: $400 + 0.3% of land value per year
- Investor rate (if you later rent the property): $1,500 + 1.1% of land value per year
- Land value assessed by Valuer General — not the purchase price
- Example: A$800,000 property, est. land value ~A$320,000 → $400 + A$960 = A$1,360/yr
- Tax is indexed to CPI annually (so it rises each year even without property value growth)
- If you sell: the next buyer gets to choose stamp duty or property tax — your choice does not bind them
- If you rent out the property: switch to investor rate ($1,500 + 1.1% of land value) — significantly higher
- If you sell to a non-FHB: the new owner must pay stamp duty (cannot stay on property tax)
- Your property tax choice is personal and tied to your FHB status — not the property
Stamp Duty vs Property Tax: What Is the Choice?
From January 2023, eligible NSW first home buyers purchasing a property up to $1,500,000 can choose between paying stamp duty (transfer duty) as a one-time upfront cost, or opting into an annual property tax instead. This is part of the NSW government's effort to improve housing affordability by reducing the large upfront barrier of stamp duty.
The right choice depends primarily on how long you plan to hold the property. If you plan to sell or move within a few years, annual property tax is cheaper. If you're buying your forever home, paying stamp duty once is cheaper long-term.
How NSW Property Tax Works
Investor Rate (if rented): $1,500 + 1.1% of land value per year
Land Value: Assessed by NSW Valuer General — approximately 30–50% of property price
Indexation: CPI-adjusted annually
Eligibility Cap: Properties up to $1,500,000 purchase price
The land value used is the unimproved value of the land — not the full property price. For a typical Sydney property, land value is often 35–50% of the purchase price depending on the suburb and property type.
Break-Even Analysis Example
$850,000 Existing Home — NSW First Home Buyer
| Stamp Duty (one-time, FHB rate) | ~$19,000 |
| Land Value (estimated 40%) | $340,000 |
| Annual Property Tax (owner-occ.) | $400 + $1,020 = $1,420/yr |
| Break-Even Year | ~Year 14 |
| 10-Year Property Tax Total | ~$14,200 |
At this price point, choosing property tax saves ~$4,800 over 10 years, but costs ~$5,200 more over 20 years (before accounting for annual CPI increases in the property tax). For a forever home, stamp duty is the better financial choice. For a starter home you plan to upgrade from in 5–10 years, property tax is more economical.
