Over the last 20 years advising Irish families, we have seen a huge change in how people structure their relationships and households.
Many couples today live together, buy homes together, raise families together, and build wealth together — without ever formally marrying.
But here is the uncomfortable truth:
Irish tax law still treats unmarried couples very differently from married couples when one partner dies.
This can lead to unexpected and sometimes devastating tax bills if proper planning has not been put in place.
Let’s look at the key areas where problems can arise.
The Family Home
For married couples, transferring the family home on death is normally straightforward.
There is no Capital Acquisitions Tax (CAT) between spouses.
However, for unmarried couples the situation is very different.
If your partner leaves you their share of the house in their will, you may face inheritance tax at 33% on the value you receive. We have seen families devastated by having to sell a house due to not having made proper plans.
The only protection available in some circumstances is Dwelling House Relief, but this is subject to strict conditions such as:
- Living in the home for three years before the death
- Continuing to live there for six years afterwards
- Not owning another property
Many couples assume their partner will automatically inherit the house without tax issues. Unfortunately, this is not always the case.
Other Assets
Bank accounts, investments, businesses, and savings are treated in the same way.
If you inherit assets from your unmarried partner, you fall into Group C inheritance tax thresholds.
The current lifetime threshold is approximately €20,000.
Anything above that amount may be taxed at 33%.
For couples who have built wealth together over many years, this can create a significant and unexpected tax liability.
养老金
Pensions can sometimes offer more flexibility.
For example, if someone dies before retirement, their pension may be payable to a nominated beneficiary.
However, the tax treatment depends on the type of pension and how benefits are structured.
In some cases, benefits may pass outside the estate. In others, inheritance tax or income tax can still arise.
Ensuring that pension nominations are up to date is a simple but often overlooked step.
Life Insurance
Life insurance is often the most effective way to protect an unmarried partner from tax exposure.
However, the policy structure matters greatly.
If a life policy is simply paid into the deceased partner’s estate, it can increase the inheritance tax problem.
Instead, policies can often be structured in trust so that funds pass directly to the intended partner while helping to cover potential tax liabilities.
Without proper planning, even life insurance can create unintended tax consequences.
Why Planning Matters
Unmarried couples often assume that because they share finances and property, the law will treat them similarly to married couples.
Unfortunately, that is not how the Irish tax system works.
Without careful planning:
- The family home could face inheritance tax
- Assets could trigger a 33% tax bill
- Pension benefits may not pass as expected
- Life insurance may not be structured efficiently
The good news is that most of these risks can be managed with proper advice and planning.
