Method & assumptionsAuthoritative sources

This calculator applies current Irish stamp duty rates as set out in the Stamp Duties Consolidation Act 1999 (as amended). For standard residential property, the rate is 1% on the first €1 million of the purchase price and 2% on the balance above €1 million. Commercial and non-residential property — including offices, retail premises, and agricultural land not qualifying for relief — is charged at a flat 7.5%. The bulk purchase surcharge of 10% is added on top of the standard residential rate where a single buyer acquires ten or more units in a single or series of linked transactions, a measure introduced in Finance Act 2021 to deter large-scale investor acquisitions.

The estimated legal fees shown are an indicative guideline only, typically ranging between 0.75% and 1.5% of the purchase price depending on complexity; actual solicitor fees vary. This calculator does not model stamp duty refund schemes, agricultural relief, consanguinity relief, or charity exemptions. Stamp duty is a self-assessment tax in Ireland; the buyer is responsible for ensuring the return is filed and payment made within 30 days of deed execution, which is normally handled by the buyer's solicitor.

Common mistakes

  • !Using an assumption that is not supported by a current local quote, bill, statement or official source.
  • !Treating a generic estimate as a lender, provider, payroll or tax authority decision.
  • !Mixing monthly and annual inputs without converting them consistently.
  • !Testing only one scenario instead of checking how a cautious assumption changes the result.

What to do next

  • Run a second scenario with a cautious assumption so you can see the downside clearly.
  • Compare the result with the related calculators below before making a decision.
  • Check current local rules, eligibility and provider terms before applying or committing money.
  • Keep a record of the assumptions so you can update the estimate when a quote, bill or pay figure changes.

Frequently asked

For residential property in Ireland, stamp duty is charged at 1% on the first €1 million of the purchase price and 2% on any amount above €1 million. These rates apply to houses and apartments purchased since October 2019. The duty is calculated on the full market value as declared in the deed of transfer, and must be paid to Revenue within 30 days of executing the deed.
