I am recently widowed and left with a large house, fully paid off. I'm thinking of selling and going in with 2 in-law siblings on another property. I'd be bringing $600 000 cash as the deposit. They'd be first time buyers and paying the resulting Mortgage. I'm on a disability pension, they work full time.
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:
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:
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.
