Buying From Parents: Do You Need a Stamp Duty Valuation NSW?

If your parents have offered to sell you their house, an investment property, or even the family farm for a “mates rates” price, it’s worth pausing before you get too excited about the saving. Revenue NSW doesn’t calculate transfer duty (still widely called stamp duty) on whatever figure you and your parents agree to write on the contract. It calculates duty on the property’s market value, and for related-party sales like this one, that almost always means you’ll need a stamp duty valuation NSW report from an independent valuer.

This catches a lot of families out. The assumption is usually “it’s a private sale between family, so we can set whatever price we like and pay duty on that.” In practice, Revenue NSW treats transfers between related parties differently to sales between strangers, precisely because there’s no independent buyer pushing back on the price. Below, we’ll walk through when a valuation is actually required, how it affects what you’ll pay, and the purpose of a property valuation when dealing with family property transfers. 

Summary

When you buy a property from a parent, Revenue NSW assesses transfer duty on the dutiable value, which is the higher of the price you actually paid and the property’s market value. Because you and your parents are related parties, an arm’s length sale price can’t be assumed, so Revenue NSW generally requires an independent valuation from a suitably qualified valuer to establish that market value.

The key things to take away:

• Paying your parents less than the property is worth (or nothing at all) does not reduce the duty payable — it’s calculated on market value regardless of price.
• A licensed, independent valuer’s report is usually needed to satisfy Revenue NSW that the value being declared is accurate.
• The same market-value transfer can also trigger capital gains tax consequences for your parents and may affect your eligibility for first home buyer concessions.
• Getting the valuation organised early, ideally before you sign anything, avoids delays at settlement and reduces the risk of Revenue NSW querying your self-assessed value later.
• A conveyancer or solicitor experienced in family transfers can tell you whether any exemptions apply to your specific circumstances, since these differ depending on structure, relationship and whether the transfer is a gift.

Why Buying From Family Isn’t the Same as a Normal Sale

When a property changes hands through a real estate agent, between two strangers negotiating at market rates, Revenue NSW is comfortable that the contract price reflects genuine market value. Neither party has a reason to inflate or deflate the figure.

That assumption breaks down the moment you’re buying from mum and dad. There’s an obvious incentive to set a low price (or no price) to keep costs down for you, or to structure the sale as part of estate planning. Revenue NSW is well aware of this, which is why the Duties Act 1997 (NSW) allows the Chief Commissioner to look past the contract price and assess duty on the property’s true market value instead.

What Counts as a “Related Party” Transfer

For stamp duty purposes, transfers between the following are generally treated as related-party or non-arm’s-length transactions:

• Parents and children (this includes adult children)
• Siblings
• Grandparents and grandchildren
• Related trusts, companies or self-managed super funds
• Any transfer not conducted through a licensed real estate agent at arm’s length

If your situation fits into any of these categories, expect Revenue NSW to want evidence of market value rather than simply accepting the contract price.

Stamp Duty Valuation NSW: How It Works for Family Sales

A stamp duty valuation is a formal, independent assessment of a property’s current market value, prepared specifically for the purpose of calculating transfer duty. It’s different from a bank valuation (which serves the lender’s purposes) or a real estate agent’s appraisal (which isn’t independent and generally isn’t accepted by Revenue NSW).

Who Can Prepare One

The valuation needs to come from a suitably qualified, independent valuer — typically someone certified by the Australian Property Institute (API). Revenue NSW has published guidance (Revenue Ruling DUT 044) setting out who qualifies. A friend’s opinion, an online estimate tool, or a council rates notice value won’t usually satisfy Revenue NSW evidence requirements; a formal valuation report prepared by a suitably qualified person may be required. 

How Dutiable Value Is Calculated

Revenue NSW uses whichever figure is higher:

1. The price actually paid (the consideration), or
2. The property’s independently assessed market value.

So if your parents’ house is worth $900,000 but you agree to pay them $500,000, duty is calculated on the $900,000 market value, not the $500,000 you’re paying. If they’re gifting it to you outright for nothing, duty is still calculated on the full market value as though you’d purchased it on the open market.

A Worked Example

Say your parents want to transfer an investment property worth $850,000 to you for $300,000, to help you get into the market while still getting something for it. Because you’re related parties, Revenue NSW will require a valuation to confirm the $850,000 figure. Transfer duty is then assessed on $850,000, not the $300,000 you’re actually paying — using the current NSW sliding-scale rates, that works out to roughly $34,900 in transfer duty at 2026-27 rates, an amount many families don’t budget for.

When You Might Not Need a Valuation

Not every family sale requires an independent valuation. It generally isn’t required where:

• The sale genuinely goes through a licensed real estate agent, is marketed at arm’s length, and the price reflects that process (even if the buyer happens to be a family member).
• The transfer falls under a specific statutory exemption, such as certain transfers between spouses or de facto partners for a principal place of residence, or transfers from a deceased estate to a beneficiary under a will.
• You’re transferring a small, defined interest where Revenue NSW’s own guidance allows a different form of evidence, such as a recent, comparable contract sale.

If you’re unsure which category your transfer falls into, it’s worth getting advice from a conveyancer or solicitor before you sign anything, rather than after.

Common Misconceptions About Buying From Parents

“We’re only charging $1, so duty will be minimal”

This is probably the most persistent myth. Selling for a nominal amount, or nothing, does not reduce your duty bill. Revenue NSW will still assess duty on the full market value.

“It’s a gift, so no duty is payable”

Gifting a property is still a dutiable transaction in NSW. If you are considering gifting a property to family in NSW, it is important to understand that transfer duty obligations may still apply depending on the circumstances. 

“We can just use the land value from the rates notice”

Council rates notices use land value for rating purposes, which is a different figure calculated differently and for a different purpose. It isn’t accepted as evidence of market value for transfer duty.

“A real estate agent’s appraisal will do”

An appraisal from an agent is a marketing estimate, not an independent valuation, and typically isn’t accepted by Revenue NSW for related-party transfers.

Other Things to Check Before You Buy From Your Parents

Capital Gains Tax for Your Parents

If the property being transferred isn’t your parents’ main residence (for example, an investment property, a holiday house, or a share portfolio-style arrangement over a farm), the transfer is a CGT event for them. The Australian Taxation Office also uses market value as the basis for calculating any capital gain, so the same valuation question comes up on the CGT side. It’s worth your parents speaking to their accountant before the transfer, since a CGT liability triggered by a family sale can be a nasty surprise.

First Home Buyer Assistance Scheme

If this will be your first property, you may be eligible for the NSW First Home Buyers Assistance Scheme, which currently provides a full transfer duty exemption on homes valued up to $800,000, and a concessional rate up to $1,000,000. Because eligibility and the discount are based on the property’s dutiable value (not the discounted price your parents are charging you), a below-market family sale could still push you over these thresholds if the property’s real market value sits above them.

Family Law and Centrelink Considerations

If you or your parents are navigating a separation, or your parents receive a Centrelink or Department of Veterans’ Affairs pension, a below-market transfer can have knock-on effects — from deprived asset rules affecting pension entitlements, to how the transfer might be viewed in later family law proceedings. These are specialist areas outside standard property advice, so get advice specific to your situation if either applies.

How the Process Usually Runs

1. Get advice early. Speak to a conveyancer or solicitor before signing anything, so you know whether a valuation will be required and what exemptions (if any) might apply.
2. Engage an independent, suitably qualified valuer. Choose someone with API certification and experience preparing reports specifically for Revenue NSW purposes, not a general appraisal.
3. The valuer inspects the property and prepares a formal report. This typically includes recent comparable sales, a description of the property, and the valuer’s assessed market value as at the transfer date.
4. Your conveyancer lodges the transfer with the valuation. Duty is assessed based on the higher of the purchase price and the valuer’s assessed market value.
5. Duty is paid, generally within three months of the contract (or at settlement if earlier). Delays here can attract interest, so timing matters.

Frequently Asked Questions

Can my parents just sell me their house for $1 to avoid stamp duty?

No. Revenue NSW assesses duty on the property’s market value, not the contract price, for related-party transfers. Selling for $1 doesn’t change the duty payable.

Do I need a valuation if I’m buying my parents’ home at full market price through a real estate agent?

Generally not, provided the sale is genuinely conducted at arm’s length through a licensed agent and the price reflects that process. Keep records showing this, such as the agency agreement and marketing history.

How much does a stamp duty valuation cost in NSW?

Fees vary by valuer, property type and location, but most independent stamp duty valuations for a standard residential property are a modest, fixed cost relative to the duty at stake. Ask for a quote before engaging a valuer.

Is a bank valuation the same as a stamp duty valuation?

No. A bank or lender’s valuation is prepared for the lender’s security purposes and generally isn’t prepared to the standard, or with the independence, that Revenue NSW requires for related-party transfers.

What happens if we don’t get a valuation and just self-assess?

Revenue NSW can request evidence of market value at any time, including after the transfer is registered, and can audit related-party transactions. If the self-assessed value is found to be too low, you may be liable for additional duty, interest and penalties.

Does the same rule apply if my parents transfer the property into a family trust I control?

Yes. Transfers to related trusts, companies or self-managed super funds are generally treated the same way as direct related-party transfers, and an independent valuation is typically required.

Conclusion

Buying a property from your parents doesn’t come with a stamp duty discount, even if the price on paper is generous. Revenue NSW assesses duty on market value for related-party transfers, so an independent valuation is usually essential to get the figure right. Getting advice and a proper valuation organised early avoids nasty surprises, delays, and potential penalties down the track.
