What a Promotion Raise Actually Nets You in Ireland: Why 10% Doesn't Feel Like 10%

It depends heavily on where your new salary lands relative to the €44,000 standard rate cut-off. A raise that stays entirely below €44,000 can keep as much as 72.8% of the gross increase. Once your salary is solidly above that threshold, a typical raise keeps only 47.8-52.8% of the gross figure, because the increase is taxed at 40% Income Tax plus USC and PRSI rather than the 20% basic rate.

Because the percentage in your promotion letter is calculated on gross salary, but every euro of that increase is taxed at your marginal rate, the rate on the next euro you earn, not your average rate across your whole salary. On an €80,000 salary with a 12% raise (€9,600 gross), the net increase is €4,589, meaning the raise that reads as 12% in your contract update actually adds roughly 5.7% to your take-home pay.

Yes, significantly. A raise from €40,000 to €44,000 (a 10% increase) stays entirely within the 20% Income Tax band and keeps 72.8% of the gross increase net. A comparable raise that pushes you from €41,000 to €45,100 crosses the cut-off partway through, and the portion above €44,000 is taxed at 40% instead of 20%, dragging the overall kept percentage down to 67.4%. The closer your current salary sits to €44,000, the more this matters when negotiating the size of a raise.

Once you are solidly above the €44,000 cut-off and the €70,044 USC upper threshold, every additional euro is taxed at roughly the same combined marginal rate: 40% Income Tax, 8% USC, and 4.1% PRSI, a combined 52.1%. That is why an €80,000 raise and a €100,000 raise both keep almost exactly 47.8% of the gross increase: both scenarios sit in the same marginal tax zone, so the percentage kept stabilises rather than continuing to fall.

This is a reasonable and common negotiating position, particularly for a raise that pushes you across the €44,000 cut-off or the €70,044 USC threshold. If you know your raise will keep only around 48% net once you cross into the higher band, framing your ask in net terms, 'I need this much in my pocket, which means asking for this much gross', is a stronger and more transparent negotiating position than assuming the employer has already accounted for it.

Yes, and it is one of the more overlooked levers in a promotion conversation. If part of your raise is directed into a pension contribution instead of taxable salary, it avoids Income Tax and USC entirely at your marginal rate, which can be worth significantly more than the equivalent cash increase once you are in the 40% band. This is worth raising directly with HR or your employer if your raise is pushing you into a higher tax band regardless.

Beating inflation is about whether your raise maintains your purchasing power against rising prices, a separate question from how much of the raise the tax system takes before it reaches you. A raise can comfortably beat inflation in gross terms and still net far less than expected once Income Tax, USC, and PRSI are applied, particularly if it crosses a tax band threshold. Both checks matter, but they answer different questions and use different maths.

Broadly yes: a bonus paid alongside a promotion is taxed at your marginal rate the same way a permanent salary increase is, through PAYE, USC, and PRSI on top of your existing salary. The difference is that a bonus is a one-off payment in a single pay period, which can trigger PAYE's emergency-style over-withholding in that period before it self-corrects, whereas a permanent salary increase is spread evenly across your future pay periods from the point it takes effect.
