In short: if you're married or in a civil partnership in Ireland you can claim the married-couple tax credit, shift unused credits and the standard-rate band between partners, and pick the assessment method that lowers your tax bill. Key points at a glance: married couple tax credit €3,550 (2026); PAYE credit €1,775 per person (2026); income taxed at 20% up to your standard-rate band and 40% above that; claim and change details via Revenue’s MyAccount or ROS. Below is a step-by-step practical guide to eligibility, how to claim, examples, common mistakes and alternatives.

Prerequisites

Before you start: both spouses must be married or in a civil partnership under Irish law. You need Personal Public Service Numbers (PPSNs) for both partners and either a Revenue MyAccount (for individuals) or ROS (Revenue Online Service) for agents or more complex returns. There’s no fee to claim tax credits with Revenue, but if you hire an accountant or tax agent they will charge their own fees — typically from around €100 for a simple change through MyAccount to several hundred euro for a full tax return or planning session.

What the key numbers mean (2026)

Key numbers for 2026 are:

  • Married couple tax credit: €3,550 for 2026.
  • Individual PAYE tax credit: €1,775 per person for 2026.
  • Income tax rates: 20% (standard rate) and 40% (higher rate).
  • Standard-rate band: income up to your personal band is taxed at 20%, the rest at 40%. Married couples can increase the band available to one spouse by transferring unused band from the other.
  • No charge to apply — claims are made online or on your tax return.

Step-by-step: How to claim tax credits for a husband and wife

Use these steps to get your married-couple credits and band transfers set up correctly for both of you.

1. Decide your assessment method

  1. Choose between joint assessment, separate assessment, or single assessment (married but treated as single for tax). Most couples opt for joint assessment because it often saves tax, particularly when one partner earns far less than the other.
  2. Joint assessment combines incomes, applies the married couple tax credit and allows transfer of standard-rate band between spouses.

2. Register and check details on Revenue MyAccount

  1. Both partners should have Revenue MyAccount (myaccount.revenue.ie). If you don’t have an account, register using your PPSN and a verification step.
  2. Under ‘Manage your tax’ you can check current credits and bands, view your RPN (Revenue Payroll Notification), and update your marital status.

3. Tell Revenue you’re married

  1. Log into MyAccount and update your marital status — this triggers Revenue to calculate joint options.
  2. If one spouse isn't on PAYE (self-employed or pensioner), you'll need to complete the appropriate return (Form 11 for self-assessed individuals) so Revenue can apply credits correctly.

4. Claim the married couple tax credit and any transfer of standard-rate band

  1. Once you update your status and select joint assessment, Revenue will usually apply the married-couple credit automatically.
  2. To transfer unused standard-rate band from one spouse to the other — do it in MyAccount or on the annual return. This reduces the higher-rate band for the lower earner and increases the standard-rate band for the higher earner, reducing tax at 40%.

5. Check payroll (RPN) with employers

  1. Once Revenue issues the updated RPN, employers apply the right tax credits and rate bands in payroll. Check payslips after the change to confirm the married tax credit and increased band appear.

6. File an income tax return if required

  1. PAYE employees who only have employment income and whose credits are correct rarely need to file a Form 11. But if either partner has self-employment income, rental income or complex credits, file a Form 11 via ROS.
  2. Make sure to claim any additional credits (medical, tuition, home carer credit if eligible) on the correct form and attach supporting documents if requested.

Practical examples

That said, example 1 — one earner: Jane earns €50,000; Tom has no income. With joint assessment Jane benefits from the married couple credit (€3,550) and can use the full standard-rate band allocation available to a married one-income couple — this reduces the total tax bill compared with separate assessment.

Example 2 — two earners: If both earn similar amounts, you might not get much extra from joint assessment apart from combined credits. But if one spouse has lower income, transferring unused standard-rate band to the higher earner can reduce tax at 40% and save hundreds of euro a year.

Tips — quick wins and practical checks

  • Tell Revenue about a marriage within six weeks — they calculate tax from the date you report the change. If you delay, you might miss credits for an earlier part of the year and need to claim a refund later.
  • Check payslips after any change — if the married credit or band transfer hasn’t applied, contact Revenue via MyAccount messages or call the Revenue helpdesk.
  • Keep proof of marriage (marriage certificate) handy — Revenue may ask for it when you change status.
  • No fee: claiming the married tax credit is free through MyAccount or ROS. If you use a tax agent expect to pay for their time.
  • Check your assessment once a year — a new job, a child or a change in income can flip which option saves you the most.

Common mistakes to avoid

  • Assuming married always means tax savings — couples with similar incomes sometimes pay more under joint assessment; check both options.
  • Forgetting to update your employer — Revenue issues an RPN, but if an employer doesn’t get it or applies old rates, you may be taxed incorrectly at source.
  • Missing deadlines for self-assessment returns — if one partner has non-PAYE income and fails to file Form 11, penalties and interest can apply.
  • Not transferring standard-rate band — many couples overlook this and pay extra at 40% unnecessarily.
  • Assuming UK/Ireland rules are the same — residency, double taxation and foreign income have special rules; seek tailored advice if you have cross-border income.

Alternatives and comparisons

If married status doesn’t produce savings, couples can opt for:

  • Separate assessment — taxed individually with each person keeping their own credits.
  • Single assessment (where allowed) — used rarely and only in specific cases.
  • Professional tax planning — especially when one partner is self-employed, has rental income, or receives foreign income. Accountants charge from roughly €200–€600 to prepare a Form 11 and advise on best assessment.
