Quick Answer
Splitting qualifying medical expenses between spouses is permitted under s.469 TCA 1997 and is often the optimal strategy for households where one spouse pays tax at 40%. The spouse with the higher marginal rate receives 40% relief on the amount allocated to them, compared to 20% for a standard-rate taxpayer.
Under section 4.6 of Revenue's Tax and Duty Manual Part 15-01-12, where more than one person contributes to the cost of qualifying health care, each person can claim only the portion they personally paid. This means the split between spouses (or between siblings for a parent's nursing home) directly affects the total family tax benefit "” particularly for nursing home fees, where the marginal rate applies.
If you want to ensure your household's medical costs are split optimally between spouses or between siblings for a parent's care, MyTaxRebate calculates the best allocation and submits both claims - at no upfront cost.

The general rule: each person claims what they paid
Revenue's health expenses guidance at s.4.6 of Part 15-01-12 states clearly: where more than one person contributes to qualifying health care costs, each person can claim only the amount they personally paid. This is the fundamental rule that governs all shared medical expense arrangements "” between spouses, between siblings, or between any other contributors.
For standard 20% health expenses (GP, prescriptions, consultant, physio etc.), the marginal tax rate is the same for all standard-rate taxpayers. In this case, whether one spouse claims all expenses or they split them evenly makes no difference to the combined total relief "” the result is 20% regardless.
When the split matters: nursing home fees at the marginal rate
The split becomes critically important for nursing home fees, because these are relieved at the individual's marginal rate "” 40% for a higher-rate taxpayer or 20% for a standard-rate taxpayer. The higher the proportion paid by the higher-rate taxpayer, the greater the total family tax benefit.
For example, where one spouse earns above the 40% threshold and the other does not, and they are contributing equally to a parent's nursing home fees of €20,000 per year (€10,000 each): the higher-rate taxpayer claims €10,000 at 40% = €4,000; the standard-rate taxpayer claims €10,000 at 20% = €2,000. Combined family refund: €6,000. If instead the higher-rate taxpayer paid €16,000 and the standard-rate taxpayer paid €4,000: the higher-rate taxpayer claims €16,000 at 40% = €6,400; the other claims €4,000 at 20% = €800. Combined: €7,200 "” €1,200 more from the same total spend.
Practical structuring for maximum relief
Where one spouse is a higher-rate taxpayer and the other is not, and both are contributing to nursing home costs:
- Have the higher-rate taxpayer pay as much of the nursing home contribution as practically possible from their own income or account.
- Keep a record of who paid what, with bank statements confirming the payments.
- Each spouse claims their own contribution "” the higher-rate taxpayer will receive 40% and the standard-rate taxpayer 20% on their respective amounts.
Joint accounts and shared expenses
Where expenses are paid from a joint account, it is generally accepted by Revenue that either spouse can claim the qualifying amount. If both are claiming, they should split the total between them. In practice, for administrative simplicity, many couples have one spouse claim all qualifying health expenses from the joint account "” this is fine for standard 20% expenses. For nursing home fees from a joint account, Revenue may accept either arrangement but structuring the payment to come from the higher-rate spouse's sole account avoids any ambiguity.
Siblings sharing a parent's nursing home costs
The same principle applies to siblings contributing to a parent's nursing home placement. Each sibling claims their own contribution at their own marginal rate. The sibling with the highest income tax rate should "” where feasible "” pay the largest share of the nursing home contribution to maximise the combined family relief. A family discussion about who makes which payments before the care arrangement begins can result in significantly better combined outcomes.

The fundamental rule at s.4.6
Section 4.6 of Revenue's Tax and Duty Manual Part 15-01-12 sets out the rule clearly: where more than one person contributes to the cost of qualifying health care, each person can claim only the portion of the cost they personally paid. This applies between spouses, between cohabiting partners, between siblings contributing to a parent's care, and between any other individuals sharing qualifying medical costs.
The principle is straightforward: the health expense relief follows the money. The person who paid the qualifying cost is the person entitled to claim it. There is no mechanism for one person to "gift" a health expense claim to another person, or to consolidate all family medical costs into a single return where not all costs were paid by the person filing.

When the split between spouses does not matter
For standard health expenses that qualify at 20% - GP visits, consultant fees, physiotherapy, prescription medicines, non-nursing-home hospital charges, dental Med 2 treatments - the split between spouses makes no difference to the total combined refund, provided both spouses are standard-rate taxpayers. Whether one spouse claims €3,000 and the other claims €1,000, or they split €2,000 each, the total 20% relief is €800 in both cases. For these expenses, couples can claim in whichever allocation is most administratively convenient.
When the split matters enormously: nursing home fees
Nursing home fees attract marginal rate relief - up to 40% for higher-rate taxpayers - which makes the allocation of payment between family members with different tax rates highly significant. The higher the proportion paid by the higher-rate taxpayer, the greater the total family tax benefit from the same total nursing home spend.
Consider a couple contributing €30,000 per year to a parent's nursing home fees. Spouse A pays 40% income tax. Spouse B pays 20%.
Over four years, this structuring difference represents €8,000 in additional recoverable tax relief on the same total nursing home spend.
- Equal split (€15,000 each): Spouse A claims €15,000 × 40% = €6,000. Spouse B claims €15,000 × 20% = €3,000. Total: €9,000.
- Optimised split (€25,000 and €5,000): Spouse A claims €25,000 × 40% = €10,000. Spouse B claims €5,000 × 20% = €1,000. Total: €11,000 - €2,000 more per year from the same total.
Joint accounts: Revenue's practical treatment
Where medical expenses are paid from a joint bank account, Revenue generally accepts that either spouse can claim the qualifying amounts from joint account payments. In practice, many couples nominate one spouse to claim all health expenses paid from a joint account - this is administratively simpler and fully acceptable for standard 20% expenses.
For nursing home fees specifically, where maximising the marginal rate benefit matters, it is cleaner and less ambiguous for the higher-rate spouse to make nursing home payments from their own personal account rather than from a joint account. This creates a clear, traceable payment record demonstrating that the higher-rate spouse paid the qualifying amount, supporting the 40% marginal rate claim.
Documenting who paid what
Where multiple people contribute to qualifying medical expenses and the allocation of payment is relevant - particularly for nursing home fees - clear documentation is important. Bank statements showing the payment of nursing home fees from a specific individual's account are the strongest evidence. Nursing home receipts or payment confirmations addressed to the specific contributor are also valuable. Retain bank statements and payment records for all years within the six-year retention window.

Tax Scenarios
Family medical bills paid by one spouse
A family pays €2,400 of qualifying medical costs in the year. At 20% relief, that element alone can support about €480 of tax relief once any reimbursed amounts are excluded.
Dental work with part reimbursement
A patient pays €1,300 for qualifying dental treatment and receives €300 from insurance. Relief is based on the unreimbursed €1,000, giving a potential tax benefit of about €200.
Higher-cost specialist treatment
A taxpayer pays €4,800 for qualifying treatment with no reimbursement. At 20% relief, the tax effect on that expense can reach about €960, which is why record-keeping matters on larger medical claims.
Common Mistakes To Avoid
- ✗Assuming the allocation of standard 20% health expenses matters when both spouses pay income tax at the same rate - for ordinary qualifying health expenses, only the existence of a tax liability matters, not the marginal rate. Both spouses recover the same 20% regardless of which one claims.
- ✗Not restructuring nursing home payment arrangements to route payment through the higher-rate taxpayer - nursing home fees qualify at the marginal rate under s.467. The 40% taxpayer in the household recovers twice the relief per euro of nursing home cost compared to the 20% taxpayer.
- ✗Paying all nursing home costs from a joint account without ensuring a clear payment trail showing the higher-rate taxpayer's contribution - Revenue may need to trace who actually paid the qualifying amount in a compliance check. Use individual account transfers rather than shared joint accounts for nursing home fee payments where possible.
- ✗Not reviewing the split annually as income levels change - if a spouse moves to or from the higher rate band during the year (e.g. after a promotion, redundancy, or maternity leave), the optimal split for nursing home costs changes accordingly. Reassess the allocation each year before filing.
- ✗Not including children's and parents' medical costs in the claim of the higher-earning spouse - for ordinary 20% health expenses, the person with the tax liability sufficient to absorb the full relief should claim all qualifying family expenses to avoid any relief being wasted.
When This Does Not Apply
Key Takeaways

- ➤ Siblings sharing a parent's nursing home costs should structure payments to maximise the combined family benefit.
- ➤ MyTaxRebate calculates the optimal contribution split between spouses or siblings to maximise family nursing home relief, then submits each individual claim - at no upfront cost.

Frequently Asked Questions
Can both spouses claim medical expenses?
Yes. Each spouse claims the qualifying costs they personally paid. If one spouse pays all expenses, they claim all. If both pay from separate accounts, each claims their own amount.
Does the split of medical expenses between spouses matter?
For standard 20% health expenses, the split between spouses makes no difference to total household relief - both recover 20% regardless of who claims. For nursing home fees relieved at the marginal rate, yes - the higher-rate taxpayer should pay as large a share as possible. Routing more nursing home costs through the higher-rate spouse can save €1,000 - €2,000 per year on the same combined spend.
What if expenses are paid from a joint account?
Revenue generally accepts either spouse claiming qualifying joint account expenses. For nursing home fees specifically, having the higher-rate spouse pay from their sole account avoids ambiguity and maximises the marginal rate benefit.
Can three siblings each claim a share of a parent's nursing home?
Yes. Each sibling who contributed to a parent's nursing home fees can claim their own portion at their own marginal tax rate under Revenue's guidance at s.4.6 of the relevant Tax and Duty Manual. A sibling paying 40% income tax recovers €400 for every €1,000 they contribute; a sibling on 20% recovers €200. Each sibling files separately for their own contribution in their own annual tax return.
Is there a limit on how much of a nursing home claim one person can make?
No. There is no cap on the amount of qualifying nursing home fees that can be claimed. The marginal rate applies to the full qualifying amount paid by that individual.
