When you sell your inherited property, you will pay Long-Term Capital Gains Tax because the combined holding period (your father's + yours) exceeds 24 months. You calculate the gain by subtracting the indexed cost of the original purchase (plus any improvement costs) from the sale price. As joint owners, you and your wife will each be taxed on your 50% share of the profit. It is recommended to use the indexation benefit or compare it with the 12.5% non-indexed rate to minimize your tax outflow.
