The 10% Stamp Duty Surcharge: What Investors Need to Know
Buy 10 or more residential properties in a 12-month period and you pay 10% stamp duty instead of 1%. This levy was designed to slow institutional bulk-buying — but it has implications for smaller investors too. Here's who it catches and how to plan around it.
Who Pays the 10% Rate?
The 10% rate applies to any person or entity that acquires 10 or more residential units in a 12-month period. This includes:
- Corporate entities (companies buying residential portfolios)
- REITs and investment funds
- Individual investors building a portfolio (if 10+ purchases in 12 months)
- Related parties acting together (anti-avoidance provisions apply)
It does not apply to: individual buyers purchasing a single home, small landlords buying one or two properties per year, or local authorities and approved housing bodies.
The Financial Impact
| Scenario | Standard Rate (1%) | Bulk Rate (10%) | Extra Cost |
|---|---|---|---|
| 10 units at €300,000 each | €30,000 | €300,000 | €270,000 |
| 20 units at €250,000 each | €50,000 | €500,000 | €450,000 |
| 50 units at €350,000 each | €175,000 | €1,750,000 | €1,575,000 |
The levy makes bulk acquisition significantly more expensive and has reduced institutional activity in the residential market. For individual investors buying 1–9 properties, the standard 1% rate still applies.
Planning Considerations
- Stay below 10: If you're an active investor, monitor your 12-month purchase count carefully
- Timing: The 12-month window is a rolling period, not a calendar year
- Related parties: Purchases by connected companies or family members may be aggregated
- Refurbishment relief: Properties bought for refurbishment may qualify for refund of the 10% levy in specific circumstances (consult a tax advisor)
