Your cash at sale will be trimmed by tax because Revenue treats disposals including sales and gifts as chargeable events and applies capital gains tax at 33 per cent. In Ireland most capital gains are taxed at that flat 33 per cent rate, although a small annual exemption and a handful of special rates and reliefs change the final amount you hand over. You must report any disposal to Revenue even if no tax is payable, and allowable costs, indexation relief for older acquisitions and business reliefs can materially alter the taxable figure. Ahead of Budget 2027 advisers and business groups have urged changes to the headline rate and to business disposal reliefs, so check Revenue.ie and Budget papers for any enacted changes.

You must file a return after a disposal, because Revenue treats the act of disposal itself as the reporting trigger.

1. Did you actually dispose of an asset

Start by establishing whether you have made a Disposal for tax purposes. Revenue guidance makes plain that a disposal is wider than the word "sale". It includes selling an asset, gifting it to someone who isn't your spouse or civil partner, transferring it for less than market value, and certain inheritances followed by a later disposal. The legal test is the event: if the asset has left your ownership in one of those ways, the disposal obligation is triggered.

That matters because the obligation to report is independent of whether tax is due. Even if, after allowances and reliefs, no cash is payable, you still must file a return with Revenue for the tax year in which the disposal occurred. Treat the reporting duty as the first compliance step.

2. Work out the chargeable gain, apply reliefs and rates

The next step is arithmetic: compute the Chargeable gain, which Revenue defines as the difference between what you received and what you originally paid, after allowable deductions. Allowable items include acquisition and disposal costs such as legal fees and auctioneer fees, and expenditure that genuinely enhanced the value of the asset. Those costs reduce the gain that gets taxed.

If the transaction was not an arm's-length sale, for example a gift to someone other than your spouse or civil partner, Revenue requires you to use the market value at the time of the disposal to determine the proceeds. Special rules apply if you owned the asset before 6 April 1974, and for assets bought before 2003 you may be entitled to Indexation relief to adjust the acquisition cost for inflation up to 2003. Indexation can reduce the chargeable gain by increasing your effective acquisition cost, but it doesn't apply after 2003.

Once you have the chargeable gains from each disposal in the tax year, add them together. Then offset any allowable losses from other disposals. From that net figure you deduct the personal Annual exemption and any qualifying reliefs to reach the taxable gain.

Individuals have a personal annual exemption, which is deducted from the combined gains for the tax year. Separate statutory reliefs, for example business disposal reliefs or reliefs linked to qualifying venture capital disposals, must be applied where the qualifying conditions are met. Apply reliefs before multiplying by the applicable rate, because the reliefs change the taxable base.

For most disposals Revenue applies a flat rate of 33 per cent to the taxable gain. That's the headline number the taxpayer will see. But Revenue sets explicit alternative rates for a handful of specific scenarios and products: gains from foreign life policies and foreign investment products may be taxed at a higher statutory rate; certain venture capital fund disposals by individuals and partnerships may attract a reduced rate; and venture capital gains for companies can be treated under the corporate rate. In narrow circumstances, separate reliefs aimed at business disposals can deliver different effective rates, and those reliefs must be checked against Revenue's published criteria.

It follows that the headline 33 per cent rate is a starting point, not the whole story. For some taxpayers parts of a gain will be taxed at those special statutory rates, and the calculation must separate the relevant portions and apply the appropriate rate to each.

After you have added gains, offset losses, deducted the personal annual exemption and applied any qualifying reliefs, multiply the resulting taxable gain by the applicable rate to compute your CGT liability. If part of a gain attracts a special statutory rate, separate that portion and tax it at the stated rate. For disposals that have incurred foreign CGT you can claim credit where applicable, but the mechanics depend on the foreign regime and how it interacts with Irish tax law.

Mastheads

Make sure the return reconciles to the supporting documents you hold. The taxpayer bears the responsibility for making an accurate assessment and payment on the return under Irish law, and Revenue expects the paperwork to match the arithmetic.

3. Special cases, record keeping and business disposals

Do not assume a gift avoids CGT. Revenue guidance, supported by recent practitioner commentary noted by the Irish Times, confirms that a gift is a disposal and that the donor is liable for tax on the gain measured by market value at the time of the gift. For example, parents who transfer a rental property to a child will crystallise a gain calculated from their acquisition cost, indexed where applicable, to the market value at the moment of the gift; the donor remains liable for CGT on that taxable gain.

Remember too that inheritance and gift tax rules, commonly called Capital acquisitions tax or CAT, are separate from CGT. A single transfer can trigger both regimes in some circumstances, but the thresholds, rates and reliefs differ. Check the relevant rules rather than assuming one regime will swallow the other.

Responsibility for the accuracy of your return rests with you, and Revenue requires contemporaneous supporting documentation. Keep purchase invoices, evidence of enhancement expenditure, legal fees and proof of disposal costs. If you rely on market value because the sale was not arm's-length, retain the valuation evidence you used.

If you claim indexation relief for pre-2003 acquisitions, or a partial relief because a part of a property was a qualifying dwelling, keep records that demonstrate dates, amounts and the nature of any qualifying use or improvement. Revenue assumes the taxpayer must be able to substantiate the figures on the return if asked.

For business owners, reliefs often matter more than the headline rate. Statutory reliefs aimed at business transfers can materially lower CGT on the sale of a trading business or qualifying shares. The details are highly specific: qualifying conditions, lifetime limits and the precise calculation rules determine whether relief applies and how much tax is saved.

Public debate and pre-budget submissions from advisers and industry groups urged reductions in the 33 per cent rate and changes to widen or raise lifetime limits on business disposal reliefs ahead of Budget 2027, according to the Irish Times. Those submissions are policy arguments. They don't change the law until Revenue guidance or primary legislation is updated, so treat them as matters for future Budgets rather than current reliefs you can assume.

4. Planning, calculators and what to watch for before you sign

Publicly available calculators provide quick estimates by automating the arithmetic, applying the personal annual exemption and common allowances, and incorporating routine adjustments such as enhancement expenditure and disposal fees. Sources such as the Irish Tax Hub publish tools and guidance that are useful for planning. Calculators are a time saver for routine cases but they don't replace the taxpayer's statutory obligation to file accurate figures and to check Revenue's published rules for special cases such as foreign life policies, venture capital disposals or business disposal reliefs.

If you plan a disposal that might trigger complex reliefs or interact with inheritance and gift tax, consider professional advice so you can confirm the tax treatment rather than relying solely on an online calculator.

Two practical checks before any transfer: first, confirm whether the disposal is treated as arm's-length or whether market value applies. Second, verify that any claimed relief meets Revenue's qualifying conditions and that you hold the supporting evidence. Those checks prevent surprises at filing time.

And keep an eye on policy debate. Industry submissions in 2026 pressed for reductions in the standard 33 per cent rate and for widening business disposal reliefs ahead of Budget 2027, according to the Irish Times. Those are proposals under active discussion, not changes in force.

In Short

- The headline rate for most capital gains in Ireland is 33 per cent, with specific alternative rates for certain products and venture capital disposals.

- Add all gains in a tax year, offset allowable losses, deduct the personal annual exemption and any qualifying reliefs, then apply the correct statutory rate.

- Gifts to non-spouses are disposals measured at market value and can crystallise a CGT liability for the donor; inheritance tax or CAT is a separate regime.

- Keep purchase invoices, evidence of enhancement expenditure, legal fees and market valuations, and check Revenue guidance or seek specialist advice for business reliefs and foreign disposals.
