Marriage creates immediate tax implications and potential refund opportunities in Ireland, requiring understanding of year of marriage treatment and subsequent assessment option selection through systematic tax planning.
In the year you get married, you and your spouse continue to be treated as single people for tax purposes. However, if the combined tax you pay as two single people exceeds what you'd pay as a married couple, you can claim a refund of the difference through a "year of marriage review."
Refunds are normally only due where couples are taxed at different rates and one spouse could benefit from:
Lower earning spouse has unused standard rate band that can transfer to higher earner
One spouse has tax credits they can't fully use that transfer to the other
The year after you get married, you have three options for how you wish to be taxed going forward:
🤝
Joint Assessment
Most beneficial for most couples
⚖️
Separate Assessment
Similar to joint but taxed as singles during year
🔀
Separate Treatment
Taxed as if not married (usually least beneficial)
Understanding the three assessment options for married couples ensures optimal tax treatment selection through comprehensive comparison of benefits, restrictions, and suitability for different income scenarios.
Joint assessment is the option that benefits most couples. Under joint assessment, you are chargeable to tax on your combined income as a couple.
Best For: Most married couples, especially those with significantly different incomes or where one doesn't work.
If you are separately assessed, you and your spouse are taxed as single people during the year, but with end-of-year credit/band transfers similar to joint assessment.
Best For: Couples who prefer individual tax responsibility during the year but want year-end optimisation.
Under separate treatment, you and your spouse are taxed as if you were not married. Also called "single assessment."
Warning: Usually results in paying MORE tax as a couple. Only beneficial in specific circumstances (e.g., complicated separate finances, pending separation).
Side-by-side comparison of the three assessment options helps identify optimal selection:
| Feature | Joint Assessment | Separate Assessment | Separate Treatment |
|---|---|---|---|
| Tax Treatment | Combined income | As singles, then adjusted | Completely as singles |
| Transfer Credits | ✅ Yes (most) | ✅ Yes (most) | ❌ No |
| Transfer Rate Band | ✅ Yes | ✅ Yes (limited) | ❌ No |
| Transfer Reliefs | ✅ Yes | ✅ Yes | ❌ No |
| Home Carer Credit | ✅ Available | ✅ Available | ❌ Not available |
| Married Credits | ✅ Full benefit | ⚠️ Divided equally | ❌ None (single credits) |
| Tax Returns | Joint/coordinated | Separate, then adjusted | Completely separate |
| Best For | Most couples | Prefer individual during year | Rarely beneficial |
In some situations, yes. In others, there will be no difference. Marriage benefits depend on income levels and tax rate differences between spouses.
Refunds/savings are normally only due where couples are taxed at different rates and one spouse could benefit from:
If one spouse doesn't earn enough to use their full standard rate band, the unused portion can transfer to the higher earner, reducing their 40% tax to 20%.
Benefit: 20% savings on transferred band amount
If one spouse doesn't earn enough to use all their tax credits, unused credits can transfer to the other spouse, directly reducing their tax bill.
Benefit: Direct €-for-€ tax reduction
If each spouse earns over €40,000 per year, there will generally be no unused tax credits or rate band to transfer to the other spouse.
At €40,000+ income, most individuals fully use their personal tax credits and standard rate band. With no unused amounts, there's nothing to transfer between spouses, so married assessment provides no additional benefit over single treatment.
Scenario: Alan earns €34,700 and Susan earns €48,000. They get married.
Standard rate band (single): €40,000
Income: €34,700
Unused standard rate band: €5,300
Standard rate band (single): €40,000
Income over standard band: €8,000 (taxed at 40%)
Can receive Alan's unused: €5,300
Transfer Impact:
€5,300 moves from 40% tax rate to 20% tax rate
Savings: €5,300 × 20% = €1,060
Annual Tax Savings from Marriage: €1,060 through standard rate band transfer!
Understanding how standard rate band transfers work enables accurate benefit calculation and optimal tax planning through systematic band allocation coordination.
Single Rate Band
€40,000
Standard rate (20%)
Married Band (1 earner)
€49,000
Standard rate (20%)
Married Band (2 earners)
€80,000
Combined maximum
Understanding which tax credits transfer and which don't ensures accurate benefit assessment and optimal credit allocation.
These credits can be allocated between spouses:
These MUST stay with the earner:
Why? These credits are tied to the specific employment/earning, so must remain with the individual who earned them.
Our PAYE specialists review 4+ years of your tax history and claim every credit and relief you're entitled to. No refund? No fee.
Claim Your Refund in 60 Seconds →One of the key benefits of joint or separate assessment is access to the Home Carer Tax Credit worth €1,700 annually.
If either you or your spouse stays at home to care for children (or incapacitated person), you can claim the Home Carer Tax Credit of €1,700.
This alone is a major reason to choose joint or separate assessment over separate treatment if one spouse stays home.
Choosing the right assessment option depends on your income levels, tax circumstances, and preferences.
Most Popular: 90%+ of couples
Alternative: Similar benefits to joint

You're treated as single people for that year. However, if the combined tax as singles exceeds what you'd pay as a married couple, you can claim a "year of marriage" refund of the difference (calculated proportionally from your wedding date). This refund is NOT automatic - you need to claim it.
Joint Assessment benefits 90%+ of couples, especially those with different incomes or where one doesn't work. It allows full transfer of most credits/bands and provides Home Carer Credit access. Separate Assessment is similar but with individual treatment during the year. Separate Treatment usually results in paying MORE tax and should be avoided unless there are specific circumstances.
Not always. If each spouse earns over €40,000, there's usually no unused credits or rate band to transfer, so marriage provides no tax benefit. Marriage saves tax when incomes are different - one spouse can benefit from the other's unused standard rate cut-off point or tax credits.
Three items CANNOT transfer: (1) Employee Tax Credit (€2,000 each), (2) Employment expenses (flat rate/actual), (3) The increase in standard rate band (earned portion). These must stay with the person who earned them. Most other credits CAN transfer.
Yes, if you choose Joint or Separate Assessment AND one spouse stays home to care for children (or incapacitated person). Worth €1,700 annually. NOT available under Separate Treatment - another reason to avoid that option.
Each spouse has a €40,000 standard rate band (20% tax). If one earns less than €40,000, the unused portion transfers to the higher earner, reducing their 40% tax to 20% on the transferred amount. Example: If one earns €34,700, €5,300 unused band transfers, saving the couple €1,060 (20% of €5,300).
The year AFTER you marry, you need to choose your assessment option. Most couples choose Joint Assessment. Professional advice helps determine the optimal choice based on your specific income levels and circumstances.
