Hey @Fregan,


The ATO administers tax and superannuation measures rather than general property purchase grants. Your in-law siblings may be eligible for first home buyer concessions, but these are generally administered by state and territory governments rather than us. It's best they check with their state or territory revenue office about grants and concessions that may apply.


One scheme the we do manage is the First Home Super Saver (FHSS) scheme. This scheme can help first‑home buyers' access some of their super contributions to help buy their first home.


There are specific eligibility and timing rules around:

  • When you can apply for the scheme.
  • Which super contributions can be released, and
  • How much time you have to use the released amounts, to buy a home.

An important thing to know about the FHSS scheme is that the person using it must legally purchase a home. Eligibility is based on the individual, not the household.


This means you can still use the FHSS scheme if you’re buying with another person who isn’t eligible. However, you can’t use the scheme if you’re only being added to a mortgage.


For you - based on what you've shared, there are a few tax-related matters you should be aware of.


When you sell your home you may be eligible for the main residence exemption from capital gains tax if the property has been your main residence.


For the new property arrangement, the tax implications will depend on how the ownership is structured. If you contribute $600,000 as a deposit while your siblings pay the mortgage, the ownership structure will determine each person's tax obligations.


If you're over 55 years old (or meet certain other conditions), you:

  • May be eligible to make a downsizer contribution to your super from the sale of your home.
  • Can contribute up to $300,000 to your super fund if you meet the eligibility requirements, including that you've owned the home for 10 or more years.

For your specific ownership arrangement and tax position, you may want to speak with a registered tax professional who can consider all your circumstances. You can also phone us directly where you have a specific tax related question and can't find the answer online.

Hi @Fregan,


I just wanted to clarify a few points based on the information you’ve shared.


From what you’ve described, it appears you already own a property, which means you wouldn’t be eligible for first‑home buyer schemes yourself.


Your family (in‑laws) may still be eligible for federal first‑home buyer schemes if they’ve never owned property in Australia. They can check First Home Buyers page on the Housing Australia website for guidance on what they may be able to apply for.
