About

NSW Stamp Duty (Transfer Duty) Calculator 2025/26 — Free Tool by Buildana

Calculate your NSW stamp duty instantly. Enter the purchase price, select the property type, and get your transfer duty figure — including first home buyer exemptions and concessions — in seconds.

No forms. No email required. Just the number you need.

HOW IT WORKS
Select your property type (existing residential, new residential, vacant land, or investment), enter the purchase price, and tick the first home buyer checkbox if applicable. The tool applies current NSW Revenue thresholds and returns your exact duty liability.

PROPERTY TYPES COVERED
• Existing residential property
• New residential (off-the-plan or newly built)
• Vacant land
• Investment / non-residential

FIRST HOME BUYER EXEMPTIONS (2025/26)
• Full exemption: existing homes up to $800,000 / new homes up to $750,000
• Partial concession: existing homes $800k–$1M / new homes $750k–$950k
• No exemption above threshold — tool calculates the standard rate automatically

WHY THIS TOOL
NSW stamp duty thresholds change, and the government's own calculator is slow and clunky. This gives you the same result in one step — useful for quickly stress-testing budgets when you're comparing multiple properties.
