When the higher rate can apply
Revenue guidance explains that a higher stamp duty rate can apply where a person acquires 10 or more individual residential units during a 12-month period. The rate is currently 15% of the consideration for relevant acquisitions.
This rule is mainly relevant to bulk residential acquisitions. A person buying one home to live in is normally dealing with the ordinary residential stamp duty bands instead.
Bulk purchase decision map
| Question | Why it matters |
|---|---|
| Are 10 or more relevant residential units being acquired? | This is the key trigger to investigate. |
| Are the acquisitions within 12 months? | The rule looks at the period, not only a single contract. |
| Are apartments involved? | Revenue guidance excludes apartments from the higher-rate rule in specified cases. |
| Are there connected parties or linked transactions? | Professional review may be needed before relying on a simple calculator. |
Why this topic should live in a guide, not the calculator form
The bulk residential rule is too specialised for the main Stamp Duty Calculator. Keeping it as a separate guide lets ordinary buyers avoid confusion while still giving investors and professional users a route to the right information.
The threshold uses a rolling 12-month period
The test is not limited to one contract, one calendar year or one closing date. Relevant acquisitions by the person—and acquisitions by connected persons where the legislation aggregates them—can be counted across any consecutive 12-month period.
| Illustrative sequence | Position to investigate |
|---|---|
| Six relevant houses acquired in January | Below the 10-unit threshold at that point. |
| Four more acquired in September | The rolling 12-month total reaches 10, so Section 31E can apply. |
| Further relevant houses before the earlier units leave the 12-month window | They may also fall within the higher-rate period. |
Earlier purchases can become subject to additional duty
Revenue guidance explains that a later acquisition can cause earlier units within the rolling period to become relevant residential units. Additional duty is then payable at the higher rate, with credit for the ordinary residential duty already paid. That adjustment is why checking only the rate on the tenth contract is not enough.
If ten relevant houses had total consideration of €3 million, a simple 15% gross figure would be €450,000. The actual additional payment depends on the instruments, acquisition dates, prior duty, connected persons, exclusions and any relief or repayment.
What is excluded or needs separate review?
- Apartments: excluded from the Section 31E higher-rate unit count, although three or more apartments in one block have their own standard residential rate treatment.
- Social and affordable housing: exemptions or repayment provisions can apply in defined circumstances.
- Leasing to specified bodies: a partial repayment may be available where every condition is satisfied.
- Indirect acquisitions: purchases through shares or interests can still require Section 31E analysis.
- Connected persons: aggregation rules can prevent the threshold being avoided by splitting acquisitions.
Frequently asked questions
Does the 15% rate apply to every second home?
No. The 15% rate is aimed at certain bulk acquisitions, not every individual second-home or investment purchase.
What is the trigger for the higher rate?
Revenue guidance refers to acquiring 10 or more individual residential units in a 12-month period.
Are apartments included?
Revenue guidance states that apartments are excluded from the higher-rate rule in the updated summary, but the details should be checked for the transaction.
Do the 10 properties have to be bought at once?
No. The rule can aggregate relevant acquisitions over a rolling 12-month period.
Can earlier purchases be charged extra later?
Yes. A later purchase can bring earlier acquisitions within the rule. Revenue allows credit for ordinary stamp duty already paid when calculating additional duty.
Are connected companies counted separately?
Connected-person aggregation can apply, so splitting acquisitions between connected buyers does not automatically keep each buyer below the threshold.
