Important Factors Influencing Stamp Duty in NSW

Understanding what affects stamp duty helps you use the calculator more effectively.

Property Value

The purchase price directly influences stamp duty. Generally, the higher the price, the more you pay. For homes priced under $650,000, concessions can significantly reduce costs.

Buyer Eligibility

  • First Home Buyer: may access concessional rates or exemptions if criteria are met.
  • Foreign Buyers: usually face higher rates and additional surcharges.
  • Existing Homeowners: may pay different rates depending on whether the property is new or established.

Property Type and Use

  • Primary Residences: often qualify for discounts or exemptions.
  • Investment Properties: attract full stamp duty rates without concessions.
  • Vacant Land: may have different regimes and extra charges.

Concessions & Exemptions

  • First Home Buyer Concession: If you’re purchasing your first home and meet criteria, you might pay significantly less.
  • Stamp Duty Exemptions: For certain properties or under specific schemes, such as affordable housing programs.

Additional Costs

  • Land Transfer Fees and Additional Levies: in some cases, local councils or specific circumstances may add extra costs.
