Who gets the most from the optimiser
Rónán is 38, a project manager in Limerick on €75,000, contributing 5% with a 5% employer match. On paper that feels responsible; against the rules it is conservative. At his age he can claim tax relief on contributions up to 20% of earnings, so 15 percentage points of relievable headroom — most of it at the 40% rate — are going unused each year. The Pension Optimiser is for exactly this situation: employees with a scheme ticking along who have never checked how far below their age-band ceiling they sit, and higher earners deciding where extra savings work hardest.
What the tool works out
From your age, gross salary, current employee percentage, employer match and marginal rate, it returns your age-band limit, your unused headroom in euro, the tax relief on your current contribution and its true net cost after relief. Toggle the My Future Fund option and it adds a ten-year auto-enrolment projection using the scheme's phased contribution rates, so you can compare both routes side by side.
The relief mathematics uses the 2026 income tax structure: 20% up to the €44,000 single cut-off point and 40% above it. Note that USC and PRSI are still charged on pension contributions — the relief applies to income tax only — which the net-cost figure reflects.
The 2026 limits that shape the answer
- Age-related relief ceilings: 15% (under 30), 20% (30-39), 25% (40-49), 30% (50-54), 35% (55-59), 40% (60 and over).
- An earnings cap of €115,000 on which relief can be claimed, regardless of how many pension products you hold.
- Marginal relief of 20% or 40% depending on where your income sits against your standard rate cut-off point.
- My Future Fund auto-enrolment, live since 1 January 2026, with employer and State contributions payable on salary up to €80,000.
Frequently asked questions
What is the maximum pension contribution I can get tax relief on?
It depends on your age: 15% of earnings under age 30, 20% in your thirties, 25% in your forties, 30% from 50 to 54, 35% from 55 to 59 and 40% from 60. Relief is calculated on earnings up to €115,000 a year, a cap that has applied since 2011. The optimiser reads your age band automatically from the age you enter.
Why does my marginal rate change what a contribution really costs?
Pension contributions attract income tax relief at your highest rate. A single earner above the €44,000 cut-off point gets 40% relief, so €100 into the pension reduces take-home pay by roughly €60; below the cut-off the relief is 20% and the same €100 costs about €80. The tool shows the net cost line explicitly for the rate you select.
How is My Future Fund different from claiming tax relief?
Under the auto-enrolment scheme that began on 1 January 2026, eligible employees aged 23 to 60 earning €20,000 or more who are not in a workplace scheme contribute 1.5% of pay, matched by 1.5% from the employer and 0.5% from the State in the first three years, with rates stepping up to 6%, 6% and 2% by year ten. Employer and State contributions stop on salary above €80,000. The State top-up takes the place of the tax-relief system rather than adding to it.
What are AVCs and does the cap include them?
Additional voluntary contributions are extra payments on top of your normal scheme contribution. All employee contributions and AVCs count together against your age-banded percentage limit and the €115,000 earnings cap, which is exactly the headroom figure the optimiser calculates for you.
Check the pension line on your payslip too
Optimising is pointless if the deduction itself is applied wrongly. Run a payslip through the Irish payslip checker to confirm your pension contribution and the tax relief on it are showing up correctly.
