How to pay less tax
legally in Ireland (2026)
Most Irish PAYE workers overpay tax every single year — not through any fault of their own, but because Revenue doesn't proactively tell you what you're entitled to. You have to claim it yourself.
This is the complete list of legal, legitimate ways to reduce your tax bill in 2026. Every item here is straight from Revenue.ie. Some will save you hundreds. One might save you thousands. And you can claim most of them in under 10 minutes on myAccount.

Pension contributions get full income tax relief at your marginal rate. If you pay 40% tax, every €1 you contribute to your pension costs you just 60c — Revenue pays the other 40c directly into your pension. No other investment in Ireland gives you an immediate 67% return.
And your pension fund grows completely tax-free — no CGT, no DIRT, no exit tax. At retirement you take 25% as a tax-free lump sum (up to €200,000).
Revenue limits by age: 20% of income (30s) → 25% (40s) → 30% (50–54) → 40% (60+). Income cap: €115,000.
How to claim: Through your employer payroll (most efficient) or declare on your annual tax return. If self-employed, claim via Form 11.
Rent Tax Credit
Since 2022, private renters can claim a €1,000 tax credit per year (€2,000 for couples). This reduces your actual tax bill — not just your taxable income — by €1,000. It's one of the most straightforward reliefs available and one of the most under-claimed.
Who qualifies: Private renters in Ireland paying rent for their principal private residence. Does not apply to rent-a-room arrangements or social housing. Your landlord must be registered with the RTB.
How to claim: Revenue myAccount → 'Manage your tax' → 'Claim tax credits' → Rent Tax Credit. You'll need your landlord's name and PPSN (or RPZ number). Claims for 2022–2025 can be made right now.
Work From Home flat rate relief
Revenue allows a flat rate of €4 per day you work from home. This covers the portion of home costs (electricity, heating, broadband) attributable to working from home. You don't need to calculate actual costs — Revenue accepts the flat rate without receipts.
| WFH days/week | Allowance/year | Tax saved (40%) | Tax saved (20%) |
|---|---|---|---|
| 1 day/week | €208 | €83 | €42 |
| 2 days/week | €416 | €166 | €83 |
| 3 days/week | €624 | €250 | €125 |
| 5 days/week (fully remote) | €1,040 | €416 | €208 |
You can also claim actual costs (electricity bills, broadband, etc.) instead of the flat rate if they're higher — but the flat rate is easier and sufficient for most.
How to claim: Revenue myAccount → Employment → Remote Working Relief. Your employer confirms the days.
Medical & dental expenses
You can claim 20% tax relief on qualifying health expenses not covered by insurance. You can claim for yourself, your spouse, and your children. You can also claim for a parent or dependent relative.
✓ Qualifying expenses
- GP visits
- Consultant/specialist fees
- Prescribed medicines
- Physiotherapy
- Non-routine dental work
- Hearing aids
- Fertility treatment
- Mental health (psychiatrist/psychologist)
- Nursing home fees
✗ Does not qualify
- Routine dental (fillings, cleaning)
- Cosmetic procedures
- Gym membership
- Vitamins / supplements
- Costs covered by insurance
How to claim: Keep all receipts (or use the Med 2 form for dental). Claim on myAccount → Health expenses. You can go back 4 years. Revenue may ask for receipts, so keep them.
Marriage & civil partnership assessment
Married couples and civil partners have three assessment options in Ireland: single, separate, or joint. Most couples who earn different salaries save money by switching to Joint Assessment — but Revenue defaults you to separate and won't move you unless you ask.
| Assessment type | Best for | Key benefit |
|---|---|---|
| Single Assessment | Default / unusual circumstances | None — treated as single taxpayers |
| Separate Assessment | Very similar incomes | Credits split 50/50 |
| Joint Assessment | Different incomes — most couples | Transfer unused credits + widen 20% band |
How Joint Assessment helps when incomes differ:
- The lower earner's unused standard rate band transfers to the higher earner (up to €35,000 extra in the 20% band)
- Unused tax credits can be transferred between spouses
- Combined, this can save up to €3,200/year for a couple where one earns significantly more
How to claim: myAccount → Manage your tax → Request Joint Assessment. Only one spouse needs to apply. Takes effect from the following tax year — so apply now for 2027.
Home Carer Tax Credit
If you're married or in a civil partnership and one of you stays home to care for children, a dependent relative, or an incapacitated person, you can claim the Home Carer Credit of €1,950 per year.
The home carer's income must be below €7,200 to get the full credit, reducing on a sliding scale up to €10,800 (above which the credit is nil). If you're already claiming Joint Assessment, you may also qualify for this on top.
How to claim: myAccount → Claim tax credits → Home Carer Tax Credit.
Third-level tuition fees relief
If you pay tuition fees for yourself, a child, or a dependent for an approved course, you can claim 20% tax relief on fees above €3,000 (the first €3,000 is a disregard). The maximum qualifying fees are €7,000 per person per year.
Part-time courses also qualify if they meet Revenue's criteria (at least 2 years duration, recognised institution). Postgraduate fees qualify in full (no disregard).
How to claim: myAccount → Claim tax credits → Third-level fees.
Bike to Work & Travel Pass schemes
Two employer-run schemes that let you pay for commuting costs from pre-tax salary:
Bike to Work: Your employer buys a bike (and safety equipment) and you repay from gross salary through payroll. The cost is exempt from income tax, USC, and PRSI — saving you effectively 40–52% depending on your tax rate. Limit: €1,250 per bike (€1,500 for e-bikes). Can be used once every 4 years.
Tax Saver Travel Pass: Annual bus/rail passes paid from gross salary. Limit: €100/month (€1,200/year). Saves the full tax+USC+PRSI. On a 40% tax + 8% USC + 4% PRSI, a €1,200 travel pass saves you roughly €624 in deductions.
How to claim: Both are employer-run salary sacrifice schemes. Ask your HR department. Self-employed people cannot avail of these.
Flat-rate profession expenses
Revenue recognises that many professions incur work-related expenses — uniforms, tools, professional subscriptions — and allows a flat-rate deduction without you needing to provide receipts. These are agreed with trade unions and industry bodies.
| Profession | Annual flat-rate deduction | Tax saved (20%) |
|---|---|---|
| Nurses / midwives | €733 | €147 |
| Teachers | €518 | €104 |
| Carpenters | €352 | €70 |
| Journalists | €317 | €63 |
| Pharmacists | €1,026 | €205 |
| Fire officers | €2,476 | €495 |
| Garda | €1,016 | €203 |
Check Revenue's full list at revenue.ie — there are over 50 occupational categories. If your job isn't listed, you can still claim actual vouched expenses.
How to claim: myAccount → Manage your tax → Claim flat-rate expenses. Stays active until you remove it.
Backdating — claim up to 4 years
In Ireland, you have 4 years to claim any tax relief or credit you didn't claim at the time. This means you can file claims for 2022, 2023, 2024, and 2025 right now in a single session on myAccount. Revenue will process a refund directly to your bank account — usually within 5 working days.
Most commonly unclaimed over multiple years: rent tax credit, medical/dental expenses, WFH relief, flat-rate expenses, tuition fees.
How to claim: myAccount → Manage your tax 2022 → add all applicable credits for each year. Repeat for 2023, 2024, 2025. Takes 30–45 minutes for all four years.
DIRT refund on savings
If you're a first-time buyer, you can claim a full refund of DIRT (Deposit Interest Retention Tax — 33%) that was deducted from interest earned on savings you used as a deposit. This applies to savings in the 4 years prior to purchase.
Not life-changing, but easy money and almost nobody claims it. How to claim: Form 54D on Revenue's website, submitted with proof of purchase.
Other reliefs worth checking
Sea-going naval personnel allowance
€6,350/year tax-free if you spend 161+ days at sea annually.
Remote working expenses (actual costs)
If your actual broadband/electricity WFH costs exceed €4/day, claim actual costs instead for a larger deduction.
Dependent relative credit
€245 credit if you maintain a dependent relative (widowed parent, incapacitated person). Small but easy to claim.
Additional Voluntary Contributions (AVCs)
Top up your employer pension scheme to the Revenue limit for the year before October 31st — and claim the relief for the previous year in the same return.
Small Benefits Exemption
Employers can give up to €1,500/year in non-cash vouchers (e.g. One4All cards) tax-free. If your employer offers this, take it — it costs you nothing and saves you effective tax on the equivalent gross.
CGT annual exemption (shares & investments)
You can realise up to €1,270 in capital gains each year completely tax-free. If you hold shares or ETFs, consider taking profits up to this limit annually — you can repurchase immediately. It's a legal "bed and breakfast" to reduce future CGT.
What could this actually be worth to you?
Here's a realistic combined saving for a single renter, earning €65,000, working 3 days a week from home, with some medical expenses:
| Relief | Annual saving |
|---|---|
| Pension (10% contribution, 40% relief) | €2,600 |
| Rent Tax Credit | €1,000 |
| WFH relief (3 days/week) | €250 |
| Medical expenses (€800 in costs) | €160 |
| Flat-rate profession expenses (nurse) | €147 |
| Bike to Work scheme (one-off, amortised) | €125 |
| Total saved per year | €4,282 |
That's €357/month that stays in your pocket instead of going to Revenue — through completely legal, straightforward claims that most people never make.
Your 30-minute tax action list
Log into Revenue myAccount (account.revenue.ie). If you don't have an account, you'll need your PPSN and a MyGovID.
Go to Manage your tax → 2022. Claim every applicable credit (rent, medical, WFH, flat-rate expenses). Then repeat for 2023, 2024, 2025.
If you're married: check if Joint Assessment would save you money. Apply if it would — takes effect next tax year.
Check your employer for pension matching — enrol if you haven't, or increase contributions. Ask HR about the Bike to Work and Travel Pass schemes.
Set a reminder each October/November to file medical expenses and any other credits for the current tax year before year-end.
