Questions people ask
What counts as the gain?
The sale price minus what you paid and the costs of buying and selling, such as broker fees, stamp duty or legal fees. Improvements to a property count as costs too.
Does it matter how long I held it?
In the US, assets held over a year get lower long-term rates. In Australia, holding over 12 months halves the taxable gain. In the UK, Canada and Ireland the holding period doesn’t change the rate.
Is my home taxed?
Selling your main home is usually exempt or partly exempt in every country here, with conditions. This calculator is for investments and second properties.
What about state or provincial tax?
US figures are federal only; most states tax gains as income too. Canada uses Ontario rates.
