Summary

Ireland charges Capital Gains Tax (CGT) on profits from disposing of assets such as shares, property, and business interests. The standard rate is 33%, but qualifying entrepreneurs may pay only 10% on the first €1 million of lifetime gains. Every individual also receives a €1,270 annual CGT exemption that reduces the taxable gain before the rate is applied. This calculator estimates your Irish CGT liability for a single disposal so you can plan sales and understand your after-tax position.

How it works

  1. Enter the disposal proceeds — the amount you received for the asset.
  2. Enter the allowable acquisition cost, including incidental purchase costs.
  3. Enter any allowable enhancement expenditure (e.g. capital improvements to property).
  4. Choose the CGT rate: 33% standard or 10% entrepreneur relief.
  5. Enter how much of your €1,270 annual exemption you still have available.
  6. The calculator deducts your exemption and applies the chosen rate to the net taxable gain.
