Joint Assessment Tax Calculator Ireland (2026)
See a married couple's combined take-home pay under joint assessment — and how much the shared standard-rate band saves you compared with being taxed as two single people.
| Combined gross | €85,000 |
| Income tax PAYE, joint | – €9,400 |
| USC both | – €1,616 |
| PRSI both | – €3,570 |
| Combined take-home | €70,414 |
A jointly assessed couple earning €55,000 and €30,000 keeps about €70,414 a year combined (€5,868/month) after income tax, USC and PRSI — roughly €1,800 more than if they were taxed separately.
When you get married in Ireland, nothing changes automatically — you have to actually opt into joint assessment with Revenue (most couples do, because it's usually the better deal). The benefit is simple: if one of you earns a lot more than the other, the higher earner can borrow part of the lower earner's tax band, so less of your combined income gets hit by the 40% rate. Put both incomes in above to see your real combined take-home and exactly what joint assessment is worth to you.

How joint assessment works in Ireland (2026)
A married couple or civil partners can be taxed three ways: jointly assessed, separately assessed, or as single people. Joint assessment is usually the most favourable, because the couple shares one standard rate band and combines their tax credits. Only income tax is shared — USC and PRSI are always worked out on each person's own income.
The shared standard rate band
| Situation | 20% band (2026) |
|---|---|
| One income | €53,000 |
| Two incomes | €53,000 + the lower of €35,000 or the lower earner's income (max €88,000) |
The €35,000 increase is not transferable — only the spouse who earned it can use it. Anything above the band is taxed at 40%. The couple's tax credits are a €4,000 Personal Tax Credit plus a €2,000 Employee (PAYE) Tax Credit for each spouse who has PAYE income.
Why it usually saves money
If both partners earn above the band, joint assessment makes little difference. But when incomes are uneven — say €55,000 and €30,000 — the higher earner can use part of the lower earner's band at 20% instead of 40%, saving around €1,800 a year in that example. A one-income couple benefits the most (about €3,800), because the full €53,000 band shelters a single salary.
Estimate for two standard PAYE employees, no pension contributions. It doesn't model self-employment, the Home Carer Tax Credit, or proportionate allocation of the band on your payslips. Confirm your own position with Revenue.
People also ask
Is joint assessment better in Ireland?
Usually yes, especially when the two incomes differ. A couple on €55,000 and €30,000 keeps about €1,800 a year more than if taxed separately. Two equal higher earners often see no difference.
How does the married tax band work in 2026?
€53,000 at 20%, increased by the lower of €35,000 or the lower earner's income — up to €88,000. The €35,000 increase can't be transferred between spouses.
Do USC and PRSI change under joint assessment?
No. Only income tax is jointly assessed. USC and PRSI are always calculated on each person's own income.
Do married couples pay less tax in Ireland?
They can — by sharing the €53,000 band and combining credits (€4,000 personal + €2,000 per earner). The benefit shrinks to nothing when both already earn above the band.
