Before you estimate Capital Gains Tax
Have the purchase cost, sale proceeds, dates, improvement costs and selling costs available before using this tool. Those figures can affect the calculation, as can your available annual exempt amount, other gains and losses, and any relief that may apply.
This is an initial guide, not a tax return. The reporting deadline and method can depend on the property, your residence status and whether tax is payable. Keep supporting records and seek advice before you report a disposal or make decisions based on an estimate.
