Tax planning for deceased estates has become more complex following the release of Tax Determination TD 2026/D1 by the Australian Taxation Office (ATO). This draft guidance focuses on when a property held in a deceased estate qualifies for the Capital Gains Tax (CGT) main residence exemption.

For many Australians, the family home is the most valuable asset in their estate. Accessing the CGT main residence exemption can significantly reduce tax liabilities for beneficiaries or trustees. However, the ATO’s stricter interpretation introduces new risks that could unintentionally deny access to this important concession.

Understanding these changes is essential for effective estate planning and protecting intergenerational wealth.

What Is the CGT Main Residence Exemption for Deceased Estates?

The CGT main residence exemption allows a property to be sold tax-free in certain circumstances after the owner’s death.

When the Exemption Typically Applies

The exemption is generally available if:

  • The property was the deceased’s main residence
  • The property is sold within two years of the date of death

Alternatively, the exemption may still apply if:

  • An individual has the right to occupy the property under the will
  • That individual uses the dwelling as their main residence until it is sold

This second pathway has now come under closer scrutiny under TD 2026/D1.

Key Changes in TD 2026/D1: A Stricter ATO Interpretation

The central issue in TD 2026/D1 is how the ATO interprets the phrase:

“Right to occupy the dwelling under the deceased’s will.”

A Literal Interpretation

The ATO has adopted a strict and literal approach, stating that:

  • The individual must be explicitly named in the will
  • General or discretionary powers granted to trustees may not be sufficient

This means many common estate planning structures could be affected.

Impact on Testamentary Trusts and Trustee Discretion

One of the most significant implications of TD 2026/D1 relates to testamentary trusts.

Trustee Discretion May Not Qualify

Where a will allows a trustee to decide who can live in the property:

  • The occupant may not qualify for the exemption
  • This is because their right is not directly granted in the will

Testamentary Trust Structures Under Pressure

Even in cases where:

  • A testamentary trust deed is attached to the will

The ATO may still consider the right to occupy as being granted outside the will, potentially disqualifying the estate from the full CGT exemption.

This interpretation could lead to unexpected tax outcomes for beneficiaries.

Why This Matters: Potential Loss of Tax-Free Status

The financial implications can be substantial.

If the exemption is denied:

  • The estate may be liable for CGT on the property
  • This reduces the overall value passed to beneficiaries
  • Long-term estate planning outcomes may be compromised

Given that property often represents a large portion of wealth, even partial loss of the exemption can have a major financial impact.

Estate Planning Strategies to Protect CGT Exemption

Although TD 2026/D1 is still in draft form, proactive planning is essential.

  1. Quantify Potential Capital Gains
  • Assess the unrealised capital gain on the main residence
  • Understand the potential tax exposure if the exemption is lost
  1. Clearly Define Occupancy Rights in the Will
  • If a beneficiary is intended to live in the property
  • Ensure they are explicitly named in the will

This is critical under the ATO’s current interpretation.

  1. Plan the Timing of Property Sale
  • Selling within two years of death may preserve the exemption
  • Delays could increase tax risk
  1. Review Testamentary Trust Structures
  • Testamentary trusts remain valuable for asset protection and tax planning
  • However, their interaction with CGT rules must be carefully reviewed
  1. Review Existing Wills and Estate Plans
  • Existing arrangements may no longer achieve the intended tax outcome
  • Professional legal and tax advice is strongly recommended

No Retrospective Relief: Why Early Action Is Critical

Based on current guidance, TD 2026/D1 does not appear to offer retrospective concessions.

This means:

  • Existing estate plans could be affected
  • Tax consequences may arise unexpectedly

Early review and adjustment of estate planning documents can help mitigate these risks.

The Complexity of CGT and Estate Planning

Estate planning involves a combination of:

  • Tax law
  • Legal structures
  • Personal objectives

The introduction of TD 2026/D1 adds another layer of complexity, particularly for:

  • Blended families
  • Complex trust arrangements
  • High-value property estates

Careful structuring is essential to ensure intended outcomes are achieved.

Conclusion: Review Your Estate Plan Before Rules Tighten

The ATO’s draft determination TD 2026/D1 signals a shift toward a stricter interpretation of CGT rules for deceased estates. While the main residence exemption remains a valuable tax concession, accessing it may now require more precise estate planning.

To protect wealth and avoid unintended tax liabilities:

  • Ensure wills are clearly drafted
  • Align legal structures with tax requirements
  • Seek professional advice where needed

Taking action now can help preserve the full value of your estate for future generations.
