How to increase your take-home pay in Ireland

None of this is about paying less tax than you owe — it's about not paying more than you owe, which happens more often than people realise. Here's where the money usually gets left on the table.

1. Claim the credits you're entitled to

Revenue doesn't apply these automatically — most need to be claimed through myAccount:

• Rent Tax Credit — 20% of rent paid, up to €1,000 for a single tenant (€2,000 for a jointly assessed couple), for private tenancies.
• Remote Working Relief — 30% of vouched electricity, heating and broadband costs for days you worked from home.
• Medical expenses — most unreimbursed medical costs qualify for relief at 20%, claimed via a Med 1 form or myAccount.
• Flat-rate employment expenses — many professions (nurses, retail workers, tradespeople) have a standard expense credit tied to their job that's easy to miss if HR never mentioned it.

These can be backdated up to four years, so it's worth checking your myAccount history even if you think you've already claimed everything.

2. Use pension contributions to cut your marginal rate

Pension contributions get income tax relief at your marginal rate — the highest rate you pay, not your average rate. If you're earning above €44,000, every euro you put into an approved pension gets 40% relief.

Example: on a €50,000 salary, contributing €2,000 to a pension only reduces your net pay by about €1,200 — the other €800 is tax you'd otherwise have paid at 40%. USC and PRSI still apply to pension contributions, which is why it's not a full 40% reduction in take-home cost, but it's still the single biggest lever most employees haven't touched.

3. Get off emergency tax fast

If you start a new job without your employer having your details on Revenue's system, you can be taxed on an emergency basis — no credits applied, and a much higher effective rate. Register the job in myAccount (or make sure your employer has your PPS number and a Revenue Payroll Notification) as early as possible; emergency tax is refunded, but only once it's fixed, not automatically before then.

4. Check your credits are split correctly if you have two jobs

Tax credits and the standard rate band can be allocated across more than one employment, but Revenue needs to be told how to split them. Left unallocated, a second job can be taxed at 40% from the first euro, with none of your unused credits applied to it.
