Review Date: 28 September 2026
A €2.25 million home does not attract Stamp Duty at 6% on the full purchase price. The duty is €65,000: 1% on the first €1 million, 2% on the next €500,000 and 6% on the remaining €750,000.
For high net worth buyers, the rate table is often the straightforward part. The more valuable advice lies in identifying what consideration must be aggregated, whether an apartment acquisition falls within the separate rule, and whether a wider investment programme could trigger the 15% bulk-acquisition rate.
These questions should be resolved before contracts are signed. Once the transaction structure is fixed, the scope for changing the Stamp Duty outcome may be limited.
The current three-tier rate structure
For instruments executed on or after 2 October 2024, the standard Irish residential Stamp Duty rates are:
| Portion of aggregate consideration | Rate |
|---|---|
| First €1 million | 1% |
| Over €1 million and up to €1.5 million | 2% |
| Balance over €1.5 million | 6% |
The bands are progressive. Crossing €1.5 million does not expose the full price to 6%. It exposes only the excess over €1.5 million to that rate.
The practical effect can be seen in three simple calculations:
- A purchase at €1 million attracts duty of €10,000.
- A purchase at €1.5 million attracts duty of €20,000.
- A purchase at €2.25 million attracts duty of €65,000.
For budgeting purposes, the formula for a standard residential purchase above €1.5 million is:
€20,000 plus 6% of the amount above €1.5 million.
The rates apply to aggregate consideration. If the purchase forms part of a larger transaction or a series of transactions, separate contracts or transfers do not necessarily secure separate use of the lower bands. Revenue calculates the duty by reference to the aggregated consideration and, where relevant, apportions it between the properties transferred under separate instruments.
This makes the commercial context important. Two ostensibly separate acquisitions may still be linked if they were negotiated as one package, are interdependent or form part of a planned series.
The apartment rule can materially change the result
A distinct rate structure applies where the consideration relates to three or more apartments in the same apartment block:
- 1% on the first €1 million; and
- 2% on the balance above €1 million.
The 6% band does not apply to a qualifying acquisition.
Compare a €2.25 million purchase:
- One high-value apartment: €65,000 under the standard three-tier rates.
- Three or more apartments in the same block for an aggregate €2.25 million: €35,000 under the apartment rule.
The number, location and legal relationship between the acquisitions therefore matter. One apartment, or two apartments, remains within the ordinary 1%/2%/6% structure even if the combined consideration is substantial. Three apartments in different blocks do not satisfy the same-block condition.
The statutory concept of an apartment block is also more precise than the label used in a sales brochure. For the bulk-acquisition rules, Revenue describes it as a multi-storey residential property comprising, or intended to comprise, at least three apartments with grouped or common access. We examine the building configuration, title documents and transaction as a whole rather than relying on the property description.
Staged completions need particular care. If separate leases or transfers implement a single agreement to acquire three or more apartments in the same block, the apartment rule may apply by reference to the larger transaction. Conversely, a later, genuinely independent purchase is not automatically aggregated with an earlier acquisition merely because the apartments are in the same development.
The question is not simply how many documents will be signed. It is what transaction those documents implement.
How the 15% bulk-acquisition rate interacts with the standard rates
Section 31E of the Stamp Duties Consolidation Act 1999 imposes a 15% rate where a person acquires at least ten relevant residential units in a rolling 12-month period. Apartments in a qualifying apartment block are excluded when counting the ten-unit threshold.
The 15% charge is not an additional surcharge placed on top of the standard rates. It replaces them for the houses that fall within Section 31E.
The rolling look-back creates the real risk. A buyer may acquire fewer than ten houses and pay the ordinary rates. A later acquisition within 12 months can take the total to ten and bring the earlier houses into the 15% regime. Additional duty then becomes payable on those earlier acquisitions, with credit for the duty already paid.
For example, assume an investor:
- acquires six houses for €3 million and pays €110,000 under the standard bands; and
- acquires four further houses for €2 million within 12 months.
The second acquisition takes the buyer to ten houses. The ultimate liability is 15% of the €5 million aggregate consideration, or €750,000. The duty already paid is credited, but the later purchase still creates a substantial current payment and a top-up liability for the first acquisition.
This is why each purchase must be tested against the buyer’s complete 12-month acquisition history and current pipeline.
The rules also look beyond the name on the contract:
- Acquisitions by connected persons may be aggregated. Connected individuals acting genuinely independently receive more nuanced treatment, but coordinated purchasing does not.
- Partial interests can fall within the regime.
- Indirect acquisitions through companies, partnerships or investment undertakings can be caught where control of the underlying houses changes.
- A bare trust is generally looked through to the beneficial owner. Trustees of fixed or discretionary trusts are themselves treated as purchasers.
Using a new special purpose vehicle, nominee or family structure does not, by itself, reset the count. The legislation contains broad anti-avoidance provisions and must be applied to the beneficial and commercial reality.
There are targeted exclusions and reliefs, including rules concerning qualifying apartments and certain social housing or public-body transactions. They are fact-specific. They should be confirmed, documented and reflected correctly in the Stamp Duty return rather than assumed at appraisal stage.
What should a high net worth buyer decide before signing?
Model the duty on the full transaction
Start with the actual consideration, including any amount attributable to connected acquisitions. For a gift or transfer at undervalue, market value may become the chargeable measure. Debt assumed by the buyer can also affect consideration.
For mixed-use property, the residential and non-residential elements attract different rates. A defensible apportionment should be agreed and supported by valuation evidence before the return is filed.
Map the buyer and the acquisition history
For a portfolio purchase, we identify the proposed legal and beneficial owner, connected persons, trusts, controlled entities and every potentially relevant acquisition in the rolling 12-month period. We also examine transactions expected to complete after the immediate purchase.
This prevents a decision that looks efficient in isolation from becoming expensive when the next transaction closes.
Test aggregation before separating instruments
There may be sound commercial, financing or title reasons to use separate contracts or complete assets in phases. But document separation is not a Stamp Duty strategy where the acquisitions form part of a larger transaction or series.
The analysis should follow the commercial agreement. Artificial fragmentation invites challenge and may also undermine the accuracy of the return.
Verify apartment status
For a multi-unit acquisition, confirm:
- that at least three units are apartments;
- that they are in the same apartment block;
- that the building meets the grouped or common-access test;
- whether multiple instruments form one larger transaction; and
- which units, if any, remain subject to the standard rates.
This work can change the projected acquisition cost materially.
Review reliefs, but do not budget on assumptions
Ireland no longer offers a general Stamp Duty exemption for first-time or owner-occupier residential buyers. Other exemptions and reliefs remain, but they address defined transactions rather than buyer wealth, status or intended occupation alone.
Where a relief is material to the investment case, we confirm the statutory conditions, evidence requirements and potential clawbacks before it is included in the financial model.
Fund and file on time
The Stamp Duty return and payment should be made within 44 days of execution to avoid late-filing surcharges and interest. On a high-value acquisition, even a short delay can create a meaningful cost.
The execution date, completion mechanics and availability of funds for duty should form part of the closing plan.
The practical conclusion
For a single high-value home, the progressive bands usually make the calculation clear. For apartment portfolios, family structures, investment vehicles and phased acquisitions, the correct result depends on facts that sit outside the price line in the contract.
We address those facts early. We map the parties and connected acquisitions, test aggregation, confirm the property’s classification, examine available reliefs and calculate the duty before the structure becomes difficult to change.
That is the point of specialist advice: not simply to calculate Stamp Duty at closing, but to ensure the acquisition is structured, priced and documented with the correct liability in view from the outset.
