Selling Property in NSW: Legal Guidelines

Written by: Marcus ThornePublished by: Sell My House PrivatelyLast reviewed June 2026

Capsule Answer

Selling residential real estate in New South Wales requires strict compliance with state and federal regulatory frameworks. Under the Conveyancing Act 1919 (NSW), property sellers must prepare a complete contract of sale containing all statutory disclosure documents before offering the property for sale. Complying with these conveyancing laws, along with ATO tax regulations (Capital Gains Tax, GST, and Land Tax), ensures a legally secure transaction, protecting your assets and preventing buyer rescission.

The Statutory Spine of NSW Conveyancing

All residential property transfers in NSW are legally governed under the Conveyancing Act 1919 (NSW) and the Conveyancing (Sale of Land) Regulation 2022. This legislation mandates that a contract of sale must be prepared by a licensed conveyancer or solicitor prior to marketing the property. The contract must attach prescribed disclosure certificates, including title searches, council Section 10.7 planning certificates, Sydney Water sewerage diagrams, and smoke alarm compliance notices.

Capital Gains Tax and GST Property Rules

Federal tax laws under the Income Tax Assessment Act 1997 (Cth) dictate tax liabilities on property sales. While primary residences (PPOR) are generally exempt from Capital Gains Tax, investment properties are subject to CGT. Individuals who hold the property for more than 12 months qualify for a 50% CGT discount.

Under GST withholding rules (Taxation Administration Act 1953), buyers of new residential properties (built within 5 years) must withhold 1/11th of the purchase price at settlement and pay it directly to the ATO, which vendors must account for in contract preparations.

NSW Land Tax and Settlement Adjustments

Land tax is a state tax governed by the Land Tax Management Act 1956 (NSW), charged on the total taxable land value of all investment properties held at midnight on 31 December. When a property is sold, land tax is adjusted proportionally between the buyer and seller on settlement day, unless the contract includes a special condition stating otherwise.

Conveyancers must obtain a land tax clearance certificate from Revenue NSW prior to settlement to ensure all tax debts are cleared.

Capital Gains Tax (CGT) on NSW Property Sales

Under the Income Tax Assessment Act 1997, Capital Gains Tax applies to the sale of residential property in Australia unless the main residence exemption is claimed. If the property was used as an investment, CGT is calculated based on the difference between the sale price and the property's cost base.

The cost base includes the original purchase price, stamp duty, legal fees, and capital renovation costs. Sourcing a tax accountant early ensures you calculate this cost base correctly.

Direct off-market transactions allow you to plan exchange and settlement dates to align with your personal tax brackets, minimizing tax.

Statutory NSW Guidelines for real estate transactions

All property sales in New South Wales must follow the Conveyancing Act 1919 (NSW). This rule applies directly to your transition involving real estate transactions.

Sellers must attach specific documents to the Contract of Sale before advertising. These documents protect both parties.

Mandatory attachments include:

- A current Land Registry Services title search copy

- A Section 10.7 planning certificate showing zoning rules

- Sewerage service diagrams from Sydney Water

- Strata certificates (if selling a strata title unit)

For relationship separations, transfers comply with the Family Law Act 1975. For deceased estates, executors must obtain probate under the Succession Act 2006. The final transfer is settled securely online.

PEXA Digital Settlement Protocols for real estate transactions

Property settlements in New South Wales must complete electronically. Conveyancers coordinate the transaction securely in the PEXA digital workspace. This workspace links banks, solicitors, and the land registry.

On settlement day, the PEXA system performs three tasks:

1. It calculates rate adjustments between buyer and seller.

2. It discharges the existing mortgage automatically.

3. It transfers the clear title to the buyer.

Funds are wired in real time. Outgoing mortgages are paid off instantly. The remaining cash goes directly to the seller's account. Title transfer occurs at the same time, ensuring total transaction safety.
