Who pays what

FHB

First home buyer

$29,580
Full exemption up to $650,000; partial up to $700,000. Buy for $1 above the full-exemption cap and the saving disappears on a sliding scale.
Investor

Resident investor

$38,930
Paid upfront at settlement, not tax-deductible in the year you pay it. It joins your CGT cost base and reduces the taxable gain when you eventually sell.
Non-resident

Foreign purchaser

$96,330
Adds a 7% foreign purchaser surcharge on top of standard duty — $57,400 extra on this price. Usually paid in cash at settlement.

What happens after you pay stamp duty

  1. Year 0

    Pay stamp duty at settlement

    Paid via PEXA to RevenueSA. It is not deductible in your next tax return — but it becomes part of your CGT cost base.
  2. Years 1–40

    Depreciation reduces your taxable rental income

    For post-1987 buildings you can claim Div 43 capital works (2.5% p.a.) plus Div 40 plant & equipment. Most investors don't realise this is worth $5K–$15K/year in deductions.

  3. Hold year 1+

    Land tax on your SA investment

    SA threshold for individuals is $732,000. Paid annually to RevenueSA. Unlike stamp duty, land tax is deductible.

  4. On sale

    CGT on the gain

    The stamp duty you paid on purchase joins your cost base — reducing the capital gain, and thus the tax. Hold >12 months to claim the 50% CGT discount.

Common questions

How is stamp duty calculated in South Australia?
SA uses progressive transfer-duty brackets administered by RevenueSA. Each bracket applies a base amount plus a per-dollar rate on the amount over the bracket floor. Foreign purchasers pay an extra 7% surcharge on the full price.
How much stamp duty on a $820,000 property in SA?
A resident investor pays approximately $38,930 in SA. A foreign purchaser pays an additional 7% surcharge. First-home buyers may qualify for partial or full exemption depending on the price.
Is stamp duty tax-deductible?
No — not in the year you pay it. Stamp duty is a capital cost, not a revenue expense. For an investment property it becomes part of your CGT cost base and reduces the eventual capital gain when you sell. For a primary residence, it is simply not deductible at all.
Do first-home buyers pay stamp duty in SA?
Not if the property costs less than $650,000 — FHB full exemption applies. Between $650,000 and $700,000 a partial concession applies. Above that, full duty.
When is stamp duty paid in SA?
Transfer duty in SA is generally payable at or before settlement, processed electronically via PEXA. Specific deadlines vary — RevenueSA publishes the exact lodgement window, which is typically 3 months from contract date.
Can I include stamp duty in my loan?
Many lenders will capitalise stamp duty into the loan, but the loan-to-value ratio (LVR) impact is the same as borrowing for any deposit shortfall. Interest on the portion of the loan that funded stamp duty on an investment property is deductible. On your primary residence, it is not.
