Understanding Deceased Estate Tax & Capital Gains: What Beneficiaries Need to Know

Will I have to pay tax (particularly capital gains tax) on inherited assets?”

When a loved one passes away, managing their deceased estate can be an emotionally difficult process. On top of that, for many beneficiaries, a key concern is: “Will I have to pay tax (particularly capital gains tax) on inherited assets?” Understanding deceased estate tax is essential, as the answer depends on several factors — when the deceased acquired the asset, how you use or dispose of it, whether it was the main residence, and whether special rules or extensions apply.

If you’re looking for expert advice — whether you live in the Inner West Sydney area (Ashfield), the Northern Beaches (Belrose), or Adelaide — a local accountant or tax agent with knowledge in deceased estates, wills, probate, and CGT can help you navigate these rules effectively.

In this post, we’ll walk you through:

1. The basics of CGT and inherited assets
2. The ATO’s rules on the cost base for assets acquired after 20 September 1985
3. When the two-year “main residence exemption” applies, and how extensions work
4. How living in an inherited property can affect your cost base/exemptions
5. Tips for beneficiaries, and when to seek advice from a local accountant or tax agent

1. CGT & Inherited Assets: The Basics

• Australia’s Capital Gains Tax (CGT) regime began on 20 September 1985. Assets acquired before that date (“pre-CGT assets”) generally don’t attract CGT when sold. (Australian Taxation Office)
• When a person dies, the passing of assets to a beneficiary or via the executor is generally not treated as a “disposal” (i.e., no CGT event) for the deceased. Instead, the beneficiary (or legal personal representative) is taken to have acquired the asset on the date of death. (Australian Taxation Office)
• The key tax issue becomes: what is the “cost base” of the asset for the beneficiary, and whether any exemptions or relief (especially for a main residence) apply.

2. Cost Base for Assets Acquired by the Deceased After 20 September 1985

If the deceased acquired the asset on or after 20 September 1985, the ATO generally treats the first element of your cost base (as beneficiary) as what the deceased’s cost base was at the time of their death. (Australian Taxation Office)

However, there is a special exception: for certain dwelling / residential properties, if they satisfy particular conditions, the first element of your cost base is instead the market value of the property on the day the deceased died. (Australian Taxation Office)

Those conditions include:

• The property passed to you (the beneficiary) (not held as joint tenants) after 20 August 1996, and
• Just before death, the property was the deceased’s main residence and was not being used to produce income. (Australian Taxation Office)

If these conditions are met, you can “reset” the cost base to the date-of-death market value (rather than inheriting the full history of the cost base).

Conversely, if the deceased acquired the property before 20 September 1985 (a pre-CGT asset), then the cost base is taken as the market value at the date of death. (Australian Taxation Office)

So in summary:

You may also include certain costs incurred by the executor or legal personal representative in your cost base (for example, legal costs to confirm the will, conveyancing costs on transfer) as long as these would have been allowable if the executor had sold the asset rather than distributing it. (Australian Taxation Office)

3. Main Residence Exemption, 2-Year Rule, and Extensions

One of the most powerful reliefs available for inherited residential property is the main residence exemption for CGT, which can often eliminate or reduce the taxable gain. But it comes with conditions.

Disposal within 2 years

If you (or the executor/estate) dispose of the inherited property within two years of the date of death (i.e. contract settled within two years), and certain main residence conditions are met, you may disregard any capital gain or loss entirely. (Australian Taxation Office)

Importantly, it’s not enough to merely sign a sale contract within two years — settlement must occur within two years. That is a commonly overlooked point.

If those conditions are met, the beneficiary or executor can “ignore” (i.e., get a full exemption) the CGT on that property. (Australian Taxation Office)

Extending beyond the 2 years

The ATO recognizes that estate administration and real-world delays sometimes make a two-year disposal impractical. Under PCG 2019/5, the Commissioner may grant a time extension (up to 18 additional months) in certain circumstances. (Australian Taxation Office)

The 2-year period may be extended automatically (i.e., without needing you to apply) if you meet all of these conditions:

• During the first two years after death, you spent more than 12 months dealing with one or more of:
    • A challenge to the will or the property’s ownership
    • Delays in the administration of the estate due to complexity
    • Delay or falls-through in settlement of a sale contract (for reasons beyond your control)
    • Life interest or equitable interest arrangements under the will that cause delay
    • Government restrictions (for example, in recent years, COVID responses) (Australian Taxation Office)
• The property was listed for sale as soon as practically feasible after the resolution of those delays, and
• The sale (settlement) was completed within 12 months of listing (i.e., not left hanging indefinitely)
• None of the delay was due to “useless excuses” — for example, waiting for market conditions, or procrastination by the executor. (Australian Taxation Office)

If you do not automatically qualify for an extension, you can apply to the ATO with supporting information showing exceptional circumstances. (Australian Taxation Office)

Effectively, under a “safe harbour” compliance approach, the two years can be stretched up to 3½ years in favorable cases.

Partial Exemption / Pro Rata

If the property does not fully qualify (e.g., it was used to produce income, or was not exclusively the main residence during the entire relevant period), you might still get a partial exemption. The capital gain is apportioned using a formula involving “non-main residence days” over “total days” of ownership (deceased + beneficiary). (Australian Taxation Office)

For properties acquired by a beneficiary after passing through a deceased estate, and where the main residence use is shared between the deceased and beneficiary, the partial exemption formula adjusts accordingly. (Australian Taxation Office)

4. Living in an Inherited Property Before Sale — What Happens?

A common scenario is that a beneficiary inherits property and lives in it for a while before selling. How does that affect CGT?

• If you live in it as your main residence and don’t use it to produce income, this can help you satisfy the “main residence” condition for the exemption. (Australian Taxation Office)
• But the timing is key: to get a full exemption, the disposal (settlement) must occur within the 2-year window (or extended window). If you delay too long, you may lose full exemption or only receive a partial exemption. (Australian Taxation Office)
• Even if you can’t get a full exemption, the fact that you used it as your main residence for some period can increase your exempt portion under a partial exemption. (Australian Taxation Office)
• Bear in mind also that if any periods the property was used for income (e.g., rented), that portion may reduce your exempt portion. (Australian Taxation Office)

Example scenario:
Suppose you inherit a property in Adelaide, live in it for, say, 4 years, then sell. If you sell after more than 2 years (and beyond any extension), you may lose the full exemption. You might be entitled only to partial exemption or none, depending on the usage patterns, and your cost base would follow the rules above (i.e., either the deceased’s cost base or date-of-death market value, depending on conditions).

5. Why You Should Consult a Local Accountant / Tax Agent (Ashfield, Belrose, Adelaide)

Understanding deceased estate tax is crucial because deceased estates, CGT on inherited assets, wills, probate, and related tax rules are a complex area. Mistakes can lead to unexpected tax bills or lost opportunities. Here’s why engaging a local accountant or tax agent, or real estate agents with relevant experience, makes sense:

• They understand local property markets, which helps in valuation, and the timing of listing and disposal
• They can liaise with local legal firms, conveyancers, and probate courts in your area (Inner West Sydney / Ashfield, Northern Beaches / Belrose, or Adelaide)
• They stay up to date with the latest ATO rulings, like PCG 2019/5, and know how to present extension requests or structuring of estates
• They can advise on wills, probate, and estate administration in conjunction with solicitors
• They can ensure that you correctly apply exemptions, extensions, and partial reliefs, and minimize tax risk

If you’re in Ashfield or Inner West Sydney, or Belrose / Northern Beaches, or Adelaide, and dealing with a deceased estate, I can help you find a trusted local accountant or tax agent to assist with the CGT, wills, probate, and clearing the estate.

6. Tips for Beneficiaries / Executors

1. Obtain a date-of-death valuation — especially for property or non-liquid assets
2. Talk to a Real Estate agent for the appraisal price for the property
3. Gather historical records — original acquisition cost, improvements, legal costs, etc., to reconstruct the deceased’s cost base
4. Act quickly — list and settle the sale within 2 years if possible to qualify for a full exemption
5. Document delays — if you run into delays beyond your control, keep evidence (legal challenges, administrative holdups) — helpful for extension requests
6. Track periods of use/income vs main residence — to apply the correct partial exemption formulas
7. Consult local specialists — a local accountant or tax agent familiar with deceased estates and the ATO’s rulings can save you time, risk, and money
