For a home in Dublin, stamp duty is generally calculated under the Irish residential property rules, rather than a separate Dublin rate. For illustration only, if an applicable rate were 1%, a €300,000 purchase would produce €3,000 in stamp duty, while a €450,000 purchase would produce €4,500; these figures are not a statement of the current rate or your liability. The amount can depend on the property type, transaction details and rules in force at the time. Check the latest guidance on revenue.ie and ask your solicitor to confirm the amount due before completing the purchase.
