Tax Implications of Divorce Ireland: Income Tax, CGT and Maintenance

The tax changes triggered by separation and divorce in Ireland are backdated, asymmetric, and full of traps for people who don't understand the rules. Revenue doesn't wait for you to file paperwork — your tax status changes from the date you actually separated, whether you notify Revenue that week or six months later.

When Your Tax Status Changes

Joint tax assessment ends on the date of factual separation — the day the marital relationship permanently ended, not the date of the divorce decree or the date you tell Revenue. If you separated in March but didn't notify Revenue until September, they'll apply the single-person assessment retroactively to March.

Year of separation. During the tax year when separation occurs, the "assessable spouse" (whoever was responsible for joint returns) is taxed on their personal income for the full year, plus their ex-spouse's income up to the separation date. They can claim the full married person's tax credit and married standard rate tax band for that year.

The "non-assessable spouse" is taxed as a single person on their income from the separation date to year-end, claiming the single person's tax credit and employee tax credit.

Subsequent years. Both parties are assessed as single individuals with single-person tax credits and standard rate bands.

Spousal Maintenance: The Tax Asymmetry

This is the tax distinction that catches most people:

Spousal maintenance under a court order or formal separation agreement is taxable income for the recipient and tax-deductible for the payer. The recipient must declare it as income and pay income tax on it. The payer deducts it from their taxable income, reducing their tax bill.

Voluntary spousal maintenance (informal arrangements with no legal backing) is tax-free for the recipient — but the payer gets no tax deduction. Neither party reports it to Revenue.

Child maintenance is always completely tax-free for the recipient, regardless of the legal structure. The payer receives no tax deduction. This applies whether child maintenance is court-ordered, part of a separation agreement, or voluntary.

The practical impact: a gross spousal maintenance award of €1,000 per month doesn't deliver €1,000 in spending power to the recipient. After income tax at their marginal rate (potentially 40% plus USC and PRSI), the net amount could be closer to €550–€600. This matters enormously when calculating whether the recipient can afford a mortgage as a sole borrower — lenders will assess the gross maintenance as income but know the tax will reduce the net figure.

The Single Person Child Carer Credit (SPCCC)

The SPCCC provides an additional tax credit (currently €1,650) and an increased standard rate tax band to a qualifying primary carer. Only one parent can claim it — the parent the child lives with for the majority of the year.

The primary carer can choose to transfer the SPCCC to the secondary carer by mutual agreement, but it cannot be split between both parents. If both parents claim it, Revenue will claw back the credit from the incorrect claimant.

Capital Gains Tax and Property Transfers

Asset transfers between spouses during marriage are normally exempt from Capital Gains Tax (CGT), stamp duty, and Capital Acquisitions Tax (CAT/gift tax). After divorce, these exemptions are preserved only if the transfer happens under a formal legal instrument:

• A court order (Property Adjustment Order)
• A properly executed Deed of Separation
• A formal divorce settlement agreement

Informal transfers — moving assets between ex-spouses without a court order or formal agreement — are treated by Revenue as taxable disposals. The transferor faces CGT on any capital gain, and the transferee faces stamp duty and potentially CAT.

The family home is exempt from CGT under Principal Private Residence (PPR) Relief regardless of the transfer mechanism. But second properties — holiday homes, rental units, investment properties — are subject to CGT on the appreciation during ownership. If a second property is transferred under a court order, the immediate CGT is deferred, but the receiving spouse inherits the original acquisition cost. They'll face a larger CGT bill when they eventually sell.

Stamp duty on property transfers between former spouses is exempt under Section 97 of the Stamp Duties Consolidation Act 1999, but only when executed under a court order or formal agreement. No court order = full stamp duty applies.

Revenue Audit Risk

Revenue pays close attention to divorce settlements because the tax treatment depends entirely on the legal structure. Common triggers for Revenue queries:

• Maintenance payments described inconsistently (spousal vs. child maintenance mixed together in the agreement, making it unclear what's taxable)
• Large property transfers without an associated court order or formal agreement
• Both former spouses claiming the SPCCC
• Failure to notify Revenue of the separation, leading to continued joint assessment when one party has remarried or changed circumstances

Getting Ahead of It

The tax implications of divorce run alongside — and interact with — every other post-divorce step: property transfers need the right legal structure to preserve exemptions, pension splitting has its own tax consequences, and maintenance calculations should always be done on a net-of-tax basis.
