How this CGT Ireland calculator works

Capital Gains Tax (CGT) in Ireland is charged on the profit you make when you dispose of an asset, such as property (that is not exempt), shares, funds, or other chargeable assets. This calculator follows a practical structure that most taxpayers use:

• Start with your total sale proceeds.
• Subtract allowable costs (purchase cost, buying/selling fees, and enhancement expenditure).
• Deduct allowable capital losses.
• Apply the annual personal exemption.
• Apply the CGT rate to the remaining taxable gain.

CGT formula used

Step-by-step calculation

Gross Gain = Sale Proceeds − (Purchase Cost + Acquisition Costs + Enhancement Costs + Disposal Costs)

Gain after Losses = Gross Gain − Capital Losses

Taxable Gain = Gain after Losses − (Annual Exemption × Number of Owners), not below zero

CGT Due = Taxable Gain × CGT Rate

The calculator displays a full breakdown so you can see exactly where your result comes from.

Important Irish CGT points to remember

1) Standard CGT rate

The standard CGT rate used in many Irish scenarios is 33%. Tax rules can change, and some specific disposals may have different treatment. If in doubt, verify current rules.

2) Annual exemption

Individuals typically have an annual CGT exemption (commonly shown as €1,270 per person). For jointly owned assets, each qualifying owner may generally claim their own exemption.

3) Allowable losses

Capital losses can reduce your taxable gain. Keep records of losses and ensure they are allowable under Irish rules.

4) Timing of payment

In Ireland, CGT has split payment deadlines depending on when the disposal is made. This calculator gives a quick estimated due date based on your disposal date entry:

• Disposals from January to November: payment is generally due by 15 December of that year.
• Disposals in December: payment is generally due by 31 January of the next year.

Example calculation

Suppose you sold an asset for €350,000. You originally bought it for €200,000, paid €9,000 buying costs, spent €25,000 on qualifying improvements, and paid €7,000 selling costs.

• Total costs: €241,000
• Gross gain: €109,000
• Less losses: €0
• Less annual exemption (single owner): €1,270
• Taxable gain: €107,730
• CGT at 33%: €35,550.90

This is exactly the kind of output the calculator provides instantly.

What to include as costs

Usually included (if allowable)

• Purchase price of the asset
• Stamp duty, legal fees, and acquisition charges
• Enhancement expenditure that improves the asset value (capital in nature)
• Selling costs, such as agent fees and legal disposal fees

Usually not included

• Routine maintenance and repair costs (revenue expenses)
• Personal labor value not actually paid as an expense
• Unsubstantiated cash expenses without proper records

Practical tips to reduce CGT exposure legally

• Keep all invoices and contracts in organized digital folders.
• Track enhancement spending as it happens, not years later.
• Use available capital losses where permitted.
• Consider timing of disposals to use annual exemptions effectively.
• Get advice before high-value transactions, especially if cross-border factors apply.
