Ireland Capital Gains Tax Calculator 2026

• 1

  Ireland publishes capital gains tax figures in Euro, revised periodically — enter the rate currently in force for your case in Ireland rather than an older stored figure so the result matches the official calculation.

• 2

  Keep the capital gains tax amount and rate for Ireland on one period and one basis — monthly Euro figures with an annual rate, or gross with net, give a number that is arithmetically right but misleading in practice.

• 3

  Treat the computed Euro amount as the base figure for Ireland: any additional local fees, deductions, or rounding rules that apply to your situation must be added separately, so the number you rely on stays honest and complete.

• Gross and net are different numbers: a Euro salary quoted for Ireland is normally gross, and the Capital Gains Tax result only matches your payslip after Ireland deductions and contributions are subtracted. Confirm which side each input represents.

• This page computes in Euro, Ireland's currency: pasting a figure from a neighboring country's calculator mixes currencies silently. Re-run the number on the matching country page so the Euro basis holds.
