Hi everyone,


We’re currently considering renting out a room in our home - we were wondering what sort of CGT implications that might arise if we sell our home later down the track. For the hypothetical we’ve been in our own home for just over 2 years if we rented out a room for 1 year and then lived without a rented room for a further 2 years - would CGT or any other implications apply if we sold our home? And if so how does the new federal budgets changes affect it?


thank you in advance

Yes, there will be CGT consequences.

CGT is calculated on the same basis

Budget changes on CGT can be viewed in the budget papers.

Budget 2026–27 Tax Explainer

The cost base on the value of the property as at 1 July 2027 will be subject to indexation when calculating the cost base. If rented for more than 12 months before 1 July 2027 then the 50% CGT discount can apply on gains accrued up to that date. (see Transitional arrangements in budget papers).

Be aware the changes are not yet law. So there may be changes to the changes before this occurs.

With the new CGT changes let’s assume they do implement them as per the budget say we purchased our home for $500k and by July 1st 2027 when the changes are due to come into effect it it now worth $700k and by 2028 it’s worth $750k are we still able to claim the 50% CGT discount on the $200k gain before changes and then pay the new tax under the new setting on the remaining $50k if that makes sense? Just trying to see if it’s actually worth doing or not
