Inherited Home CGT: Protect Yourself from Unintended Capital Gains Tax
Protect your estate with our guide on Inherited Home CGT and the 2026 TD 2026/D1 ruling. Learn the “Right to Occupy” rules to avoid costly tax traps.
For most Australian families, the family home is the most significant asset in a deceased estate. Historically, the Main Residence Exemption (MRE) has provided a critical tax shield, allowing beneficiaries to inherit and sell a property without a massive Capital Gains Tax (CGT) bill. However, a significant shift in the ATO’s interpretation—specifically the release of Draft Determination TD 2026/D1—has introduced a technical trap that could cost estates hundreds of thousands of dollars.
The core of this update focuses on the “Right to Occupy.” If your family estate planning relies on a trustee’s discretion rather than an express command in the will, you may be unknowingly walking into a CGT liability. This is why our Retirement and Estate Planning services prioritize clear testamentary instructions.
Inherited Home CGT – The “Right to Occupy” Under TD 2026/D1 Draft
The ATO’s latest position clarifies a long-standing ambiguity regarding when a property continues to be treated as a “main residence” after the owner has passed away. Under Section 118-195 of the ITAA 1997, to maintain the exemption during the period between death and sale, the property must often be the main residence of a person who has a “right to occupy” it under the deceased’s will.
Previously, many executors assumed that if they allowed a surviving spouse or adult child to remain in the family home, the “main residence” status would remain intact. TD 2026/D1 changes this. The ATO now asserts that the “right” must be legally enforceable against the executor, rather than a mere permission granted by the executor.
Will vs. Trustee Discretion (The $70k Distinction)
The 2026 ruling draws a hard line: the right to occupy must be an express right granted by the will itself. If the will simply gives a trustee “discretion” to allow a beneficiary to live in the house, the ATO now views this as insufficient. Because the beneficiary does not have an absolute right under the “will,” the main residence exemption may be denied for the period they lived there, potentially triggering CGT on years of property growth. This subtle linguistic difference is the primary driver behind modern estate planning failures.
Estate tax laws have shifted significantly in 2026, making a review of your current will and property titles essential for asset protection.
Home-Based Businesses and CGT Concessions
Many inherited properties are now being used by beneficiaries as home-based business hubs. While the ATO supports small business growth, the interaction between the Main Residence Exemption and Small Business CGT Concessions has become more complex in 2026.
When a beneficiary uses an inherited home for business purposes, they must navigate the “Active Asset Test.” This requires the property to be used in the course of carrying on a business for at least half the period of ownership (or 7.5 years if owned for more than 15 years). However, the moment a home becomes an income-producing asset, the MRE is pro-rated. Our Accounting and Tax team can assist in modeling these specific impacts to ensure you aren’t hit with a “tax surprise” upon the final sale of the estate.
The Active Asset Test for Residential Properties
For a home-based business to qualify for CGT concessions, the property must pass the active asset test holistically. However, using a portion of an inherited home for business can “apportion” the MRE, meaning a percentage of the home becomes subject to CGT upon sale. It is vital to determine if the 15-year exemption or the 50% active asset reduction applies before assuming the sale will be tax-free. Often, the difference between a fully exempt sale and a taxable one comes down to how well the “business use” was documented during the transition period.
Practical Checklist for Executors and Trustees
Navigating a deceased estate is emotionally taxing; technical tax errors only add to the burden. Below is a practical checklist for executors to ensure compliance with 2026 standards.
5 Key Verifications for 2026 Compliance
[ ] Review the Will: Does it contain an “Express Right to Occupy” for the surviving spouse or child?
[ ] Establish the Timeline: Has the property been sold within the “two-year rule” window?
[ ] Document Main Residence Status: Is there evidence (utility bills, electoral roll) that the occupant used the home as their primary residence?
[ ] Audit Business Use: If the deceased (or beneficiary) ran a business from home, has a floor-plan apportionment been calculated?
[ ] Check Cost Base Reset: Have you obtained a formal valuation as of the date of death to establish the new cost base?
Calculating the Cost of Non-Compliance
Case Study: Discretionary Occupancy vs. Express Rights
Imagine a property valued at $1,500,000 at the time of death in 2024. The beneficiary lives in the home for three years under a “trustee’s discretion” clause before selling it for $2,100,000 in 2027.

In this example, a single word in the will—”discretion”—costs the family $70,000. This highlights why “Information Gain” strategies are about more than just reading the news; they are about avoiding mathematical traps. Proper Business Planning and Strategy often begins with these structural details.
Maintaining SMSF Integrity in Estate Planning
Finally, for those holding property within an SMSF, the Sole Purpose Test remains the ATO’s primary focus. When a member passes away, the transition of that property must be handled with strict adherence to arm’s length requirements. The ATO is particularly wary of “death benefits” that are delayed to allow a family member to stay in an SMSF-owned property at below-market rates.
Related-Party Arrangements in 2026
If an SMSF property is being transferred to a beneficiary or leased to a related party during the estate settlement, the rent must stay at strict market value. The ATO has increased its audit frequency for “under-market” leases in 2026, which can lead to the fund being deemed non-compliant, triggering a tax rate of 45% on the entire fund’s value. This “compliance hammer” is far more damaging than the CGT bill itself, making arm’s length documentation non-negotiable.
Conclusion
The complexity of TD 2026/D1 and the ATO’s intensified focus on “Right to Occupy” clauses demonstrate that estate planning is no longer a “set and forget” task. By aligning your will with current tax definitions and maintaining strict SMSF compliance, you can ensure your wealth is transferred to the next generation without unnecessary tax leakage. Proactive review remains your most effective defense against these evolving legislative traps.
Don’t let a poorly drafted clause or an overlooked ATO ruling compromise your family’s financial legacy.
