One of the most searched questions regarding marriage and taxation is around year of marriage relief. Many assume their tax position updates immediately and wonder why they don’t see a change in their net pay. In reality, it doesn’t work like that.
How tax works in the year you get married
In the year of marriage, you are still taxed as single individuals.
This means:
- Your PAYE continues as normal
- Your tax credits and bands don’t automatically combine during the year
Only after the end of the tax year can you ask Revenue to review your position.
What is year of marriage relief?
After 31 December, you can request a review to see if you paid more tax than you would have under joint assessment. If you did, Revenue will issue a refund.
👉 Important:
- The calculation only applies from the date of marriage onwards.
- It is not backdated to the start of the year. (But will include the whole month in which you got married, e.g. if you marry on 31st July, it will include all of July).
Example: how year of marriage relief works in practice (2026)
Let’s take a simple example.
- You marry on 1 July 2026
- Person A earns €60,000 for the full year
- Person B earns €20,000 for the full year
Step 1: How you’re taxed during the year
For 2026, you are taxed as single individuals:
- Each person has a €44,000 standard rate band
👉 Person A:
- €44,000 taxed at 20%
- €16,000 taxed at 40%
👉 Person B:
- €20,000 taxed at 20%
Total combined income tax: €19,200
Step 2: Revenue recalculates your tax position
After the year ends, Revenue compares:
- Your actual tax paid as two single people, and
- What your tax would have been if you were jointly assessed for the full year
Step 3: Recalculate as if jointly assessed for the full year
Combined income:
- Person A: €60,000
- Person B: €20,000
- Total: €80,000
Under joint assessment (2026):
- Base band: €53,000
- Increase: €20,000 (based on lower earner)
- Total standard rate band: €73,000
👉 So:
- €73,000 taxed at 20%
- €7,000 taxed at 40%
Total combined income tax: €17,400
Step 4: Compare the two positions
Under single treatment:
- More of Person A’s income is taxed at 40%
Under joint assessment:
- More of the combined income is taxed at 20%
👉 Result:
- A tax saving arises due to better use of the lower rate band. €19,200 – 17,400 = €1,800 difference.
Step 5: Apply time apportionment
You married on 1 July, so Revenue only applies the benefit for 6 months of the year.
👉 The tax saving is reduced by 6/12 = €900.
Final outcome
Revenue calculates the difference between the two positions and issues a partial refund. In our example, a refund of €900.
👉 Key points:
- The refund only relates to the period after marriage
- It is based on actual tax paid by each person
- It is split between both spouses proportionally.
How to claim
- Wait until after the end of the tax year
- Submit a request via myAccount (myEnquiries)
Revenue will calculate the position and issue any refund due.
Common misconceptions
- “We’ll pay less tax straight away” → ❌ Not in the year you marry
- “It applies for the full year” → ❌ Only from date of marriage
- “Revenue does it automatically” → ❌ You need to request the review
Final point
Year of marriage relief is a post-year adjustment, not an immediate saving.
