Realisations on or after 3 June 2026 are taxed at 15%. Critical to record transaction date accurately.IRA (Amendment) Act No. 11 of 2026
Valuation by qualified valuer
To substantiate the cost basis (acquisition cost) and avoid IRD substituting a different market value, it is advisable to obtain a professionally qualified valuer's report at the time of realisation.IRA s 37
