More couples than ever in Ireland are choosing not to marry—but very few realise the serious tax consequences that decision can create.
From inheritance tax to life cover structures and even day-to-day tax planning, unmarried couples are treated completely differently under Irish tax law.
If you’re living with a partner, own a home together, or rely on one income, this is something you cannot afford to ignore.
⚠️ 1. The Biggest Risk: Inheritance Tax on Death
Married couples and civil partners benefit from full tax exemption when assets pass between them.
Unmarried couples?
They don’t.
👉 What actually happens:
If one partner dies and leaves assets (including a home) to the other:
- The surviving partner falls into Group C CAT threshold
- Current threshold: €20000 (approx.)
- Tax rate: 33% on anything above this
💥 Example:
- House value inherited: €400,000
- Tax-free threshold: €20,000
- Taxable amount: €380,000
- Tax bill: ~€125,400
👉 That’s a six-figure tax bill—often due within months.
🛡️ 2. Why Life Cover Must Be Structured Properly
Many couples think:
“We have life insurance, we’re covered.”
But here’s the issue:
❌ If structured incorrectly:
- Policy pays out to surviving partner
- Revenue treats it as a gift/inheritance
- 33% tax may apply
✅ The correct structure:
A Section 72 life policy (or properly structured policy in trust) can:
- Cover the expected CAT liability
- Ensure the payout is tax-efficient
- Protect the surviving partner from financial distress
👉 This is not just about having cover—it’s about how it’s set up
🏠 3. Dwelling House Relief – Not a Guaranteed Solution
Some unmarried partners assume they qualify for Dwelling House Relief.
But this relief is:
- ❗ Highly restrictive
- ❗ Increasingly scrutinised by Revenue
- ❗ Not guaranteed to apply
Key conditions include:
- Living in the property for 3+ years prior to death
- No ownership of any other property
- Continued occupation after death
👉 In practice, many claims fail or are challenged
💼 4. Tax Planning Opportunity: Employing a Partner
This is where things get interesting—and often overlooked.
If one partner is:
- Self-employed or a business owner
- And the other is a stay-at-home partner
👉 There may be a legitimate tax planning opportunity
✅ By employing your partner:
You can:
- Use their lower tax bands
- Create a deductible business expense
- Build their PRSI record and pension
- Potentially reduce the overall household tax bill
💡 Example:
Instead of one partner earning €80,000:
You split:
- €50,000 (business owner)
- €30,000 (employed partner)
👉 Result:
- Lower overall income tax
- Better use of credits and bands
- Increased household net income
⚠️ Important:
This must be:
- A genuine role
- Paid at a commercial rate
- Properly documented
Otherwise, Revenue may challenge it.
🧠 5. The Bigger Picture: You Need a Strategy, Not Just Products
Most unmarried couples:
- Have no tax plan
- Have incorrectly structured life cover
- Assume “it’ll be fine”
👉 It won’t be—unless it’s planned properly.
✅ What You Should Be Doing Now
If you’re an unmarried couple, you should:
- Calculate your potential CAT exposure
- Review how your life cover is structured
- Assess eligibility for Dwelling House Relief (realistically)
- Explore income splitting opportunities (if self-employed)
- Put a clear plan in place
🚨 Final Thought
The difference between married and unmarried couples in Ireland isn’t small—it’s financially life-changing.
With the right advice:
- You can eliminate or fund tax liabilities
- Protect your partner
- Improve your overall financial position
Without it:
- Your partner could face a significant tax bill at the worst possible time
💬 Call to Action
If you’re in a long-term relationship and not married, it’s worth having a conversation.
“Are we exposed to tax if something happens to one of us?”
If you don’t know the answer, that’s the risk.
