Ireland income tax calculator

Two rates, three charges, and none of them is the whole story

Ireland has only two income tax rates — 20.0% and 40.0% — which sounds like the simplest system on this site and is not. Three things sit between the rates and what leaves your pay.

The standard rate band is where 20.0% stops and 40.0% begins, and it is not a single figure: €44,000 for a single person, €53,000 for a married couple with one income, more again with a qualifying child. The band is a personal circumstance rather than a constant.

Tax credits come off the tax, not off the income. A single employee gets €2,000 of personal credit and €2,000 of employee credit — €4,000 together, which is exactly 20.0% of €20,000. That is why an Irish salary of €20,000 produces €0 of income tax.

The USC is a separate progressive charge on gross income with its own four bands, and the credits do not touch it. On €20,000 the income tax is nothing and the USC is €220 — so someone who reads "no income tax" as "no deduction" is wrong by that amount.

On €50,000 the three together give €7,200 of income tax and €1,033 of USC, €8,233 in all, an effective rate of 16.5%. PRSI comes off on top and is not included.

The band is personal, and that is the planning lever

Because the standard rate band varies by circumstance rather than being fixed, an Irish household's tax depends on how income is arranged between two people in a way that does not arise in most systems here.

A married couple or civil partners can transfer a portion of the standard rate band and most credits between them. Where one earns much more than the other, moving band to the higher earner keeps more income at 20.0%.

There is a limit. The transferable portion is capped, so a couple cannot simply pool everything — which means the optimum is a calculation rather than a default, and it changes when either income changes.

On €50,000 the single figure is €7,200 of income tax and the married one-income figure is €4,000 — a difference of €3,200 produced entirely by the wider band and the larger personal credit.

Joint assessment is generally the default for married couples and civil partners, but separate assessment and separate treatment both exist and produce different answers. It is one of the few genuine elections in the Irish personal system.

The USC, which behaves like a tax and is not one

The Universal Social Charge was introduced as an emergency measure and became permanent. It is charged on gross income with its own bands: 0.5%, 2.0%, 3.0% and 8.0%.

Two properties make it consequential. It is charged on gross income rather than on income after reliefs, and tax credits do not reduce it — so the mechanism that wipes out income tax at lower salaries leaves the USC entirely intact.

That is why the marginal rate people quote in Ireland is usually the combined one. At €100,000 the income tax band is 40.0% and the USC band is 8.0%, so the next euro costs 48.0% before PRSI — and with PRSI the commonly quoted figure is higher still.

There is an exemption below a total income threshold, so the charge does not arise at all for the lowest incomes. That exemption is not modelled here, which means the USC shown for a very low income is an overstatement.

Reduced rates apply to certain groups, including some medical card holders and people over 70 with income below a threshold. Those are not modelled either.

The same salary at four incomes

The Irish effective rate is unusually low at the bottom and rises steeply, because the credits are a fixed amount that matters enormously on a small salary and barely at all on a large one.

On €25,000: €1,000 of income tax after €4,000 of credits, plus €320 of USC. Total €1,320, an effective 5.3%.

On €40,000: €4,000 of income tax after €4,000 of credits, plus €733 of USC. Total €4,733, an effective 11.8%.

On €60,000: €11,200 of income tax after €4,000 of credits, plus €1,333 of USC. Total €12,533, an effective 20.9%.

On €100,000: €27,200 of income tax after €4,000 of credits, plus €4,031 of USC. Total €31,231, an effective 31.2%.

Read the first and last rows together. Income quadruples and the effective rate more than triples — a steeper progression than almost any other country on this site, and it comes from a two-rate system, which is not the intuition most people have about flat-ish structures.

Five ways an Irish estimate goes wrong

Treating credits as an allowance. They come off the tax, not the income. €4,000 of credits is worth €4,000, not 20.0% of it.

Forgetting the USC. It is a separate charge on gross income that credits do not reduce. At €20,000 the income tax is nothing and the USC is €220.

Using one standard rate band for everyone. It is €44,000 single and €53,000 for a married couple with one income, and more with a qualifying child.

Leaving out PRSI. It is a further deduction from wages, not included here, and it is why the commonly quoted Irish marginal rate is higher than the 48.0% of income tax plus USC.

Assuming the marginal rate is 40.0%. Add USC and it is 48.0% at higher incomes before PRSI. The two-rate headline is the least informative number in the Irish system.

Where these figures come from

The rates, bands and credits came from Revenue — Tax rates, bands and reliefs (2026), and the USC bands from Revenue — Standard rates and thresholds of USC (2026), both read on 2026-09-02. Revenue publishes them separately, which is part of why so many summaries cover one and not the other.

Ireland uses the calendar year, which makes it simpler than the UK next door — and the two systems are otherwise less alike than their proximity suggests: Ireland uses credits where the UK uses an allowance, and Ireland has a third charge the UK does not.

Only the personal and employee credits are applied here. Rent credit, home carer credit, medical expenses relief and tuition relief all exist and are not modelled, so this is an upper bound for anyone entitled to them.

What is not modelled is stated under the calculator: PRSI is not included. It is a separate social insurance contribution deducted from wages alongside income tax and USC, and it is a real reduction in take-home pay. The USC exemption for low total income is not applied. Below a threshold the charge does not arise at all, so for very low incomes the USC shown here is an overstatement. Only the personal and employee credits are applied. Rent credit, home carer credit, medical expenses relief, tuition relief and the rest are not, so the figure is an upper bound.

The arithmetic is deterministic. The AI explains figures it is given and never produces one.

How Ireland compares with the rest of this site

Against the UK, the two are less alike than geography suggests. The UK gives a Personal Allowance — an amount of income taxed at nothing — and withdraws it above €100,000-equivalent. Ireland gives credits against the tax and does not withdraw them, so Ireland has no equivalent of the UK's 60% band.

Against the Netherlands, the mechanism is closer: both use credits. The difference is that Dutch credits taper with income and Irish ones do not, which is why the Dutch marginal rate spikes and the Irish one simply steps from 20.0% to 40.0%.

Against Germany, Ireland is the opposite extreme: two rates against a continuous formula. Germany has no thresholds at all; Ireland's whole system turns on one.

Against the US, the closest parallel is joint filing. Ireland lets a married couple transfer band and credits between them, which is a partial version of what a US joint return does automatically.

What Ireland has that none of the others do is a third charge with its own progressive scale that credits do not touch. The USC is genuinely distinctive, and it is why the Irish marginal rate is never the headline rate.

PRSI, the charge this page leaves out

PRSI is social insurance, deducted from wages alongside income tax and USC. It is not modelled here, and anyone comparing this figure against a payslip should expect the payslip to be lower.

Unlike the USC it is contributory in the proper sense: it buys entitlement to a range of benefits including the State Pension, and the number of contributions recorded over a working life determines what is payable. That makes it closer to National Insurance in the UK or CPP in Canada than to a tax.

It is charged from a low income threshold and applies to employment income broadly. There is a credit that tapers the charge in for lower earners, which softens the entry point.

The reason it is excluded rather than estimated is that the rate has been on a scheduled series of increases, and publishing a figure that is right for one part of a year and wrong for another would be worse than stating the omission.

Adding it is why the marginal rate commonly quoted in Irish public debate is higher than the 48.0% that income tax and USC produce together.

Filing, and how little most employees do

PAYE handles most of it. Revenue operates real-time reporting, so the credits and band on your record are applied through the payroll and adjusted when your record changes.

The record is the thing worth checking. Credits you are entitled to but have not claimed simply do not appear — rent credit, medical expenses relief, tuition relief and the home carer credit are all claimed rather than granted.

Medical expenses relief is claimed at 20.0% of qualifying costs and is one of the most commonly missed. Four years of unclaimed relief can be recovered, which is a reason to look back rather than only forward.

An end-of-year statement of liability shows whether the year over- or under-deducted. Requesting one is how a refund arrives, and it does not happen automatically for everyone.

Ireland uses the calendar year, so none of this involves the split-year arithmetic that the UK, Australia, New Zealand, India and South Africa all require.

The standard rate band, and the part couples get wrong

The single band is €44,000. Income up to it is charged at 20.0%; everything above at 40.0%. That is the whole income tax scale, before credits.

For a married couple or civil partners jointly assessed, the band is larger — but the increase is not unlimited and it is not symmetrical. A couple with one income gets €53,000. A couple with two incomes can go higher, but only up to the lower earner's actual income, and the increase cannot be transferred beyond that.

The consequence catches people out in both directions. A couple where one partner earns everything cannot access the full two-income band, because there is no second income to justify it. And a couple with two similar incomes gains nothing from joint assessment on the band at all, because each was already using their own.

Where joint assessment does reliably help is where one partner earns below the band and the other above it: the unused portion of the lower earner's band, up to the transferable limit, shifts across and moves income from 40.0% to 20.0%.

The calculator models the single case and the one-income married case. A two-income couple should model each partner separately as single and treat the result as the ceiling, since joint assessment can only reduce the total.

Credits, and why they beat allowances at the bottom

Ireland's two universal credits — the personal credit and the employee PAYE credit — are each €2,000, so a single employee starts with €4,000 off the tax.

A credit is worth the same to everyone. €4,000 off the tax is €4,000 whether your top rate is 20.0% or 40.0%. An allowance of the same size — an amount of income taxed at nothing, as in the UK — would be worth €800 to a basic-rate payer and €1,600 to a higher-rate one.

That difference is the reason Ireland has no equivalent of the UK's 60% band. The UK withdraws its allowance above a threshold, and withdrawing a relief whose value rises with income produces a spike. Ireland's credits do not taper, so nothing to withdraw means nothing to spike.

The self-employed get an earned income credit in place of the PAYE credit, at a comparable amount, which closes most but historically not all of the gap between employment and self-employment.

Beyond the universal two, credits are claimed rather than granted: home carer, single person child carer, rent, and the age credits all require a claim. Revenue applies what it knows about, and it does not know about most of these unless told.

Reading the USC bands correctly

The USC has four steps and they are narrow at the bottom: 0.5% on the first €12,012, 2.0% on the next €16,688, 3.0% on the next €41,344, and 8.0% on everything above.

The single most common error is treating the whole of income as charged at the rate its top slice reaches. The bands are marginal, exactly like the income tax bands, so someone on €60,000 pays the 8.0% rate on nothing at all — their income has not reached the top band.

The second most common is missing the exemption. Below an annual income threshold, no USC is due on any of it — not a reduced rate, none. Cross the threshold by a euro and the whole income becomes chargeable under the band structure, which makes it one of the genuine cliffs in the Irish system.

Certain income is outside the charge altogether, including social welfare payments, and medical card holders below an income limit pay a reduced maximum rate. Neither is modelled here.

Self-employed income above €100,000 carries a surcharge on top of the top USC rate, which is why the often-quoted top marginal rate for the self-employed exceeds the 48.0% an employee faces.

Where the Irish marginal rate actually jumps

There is exactly one large step in the income tax scale: the move from 20.0% to 40.0% at the top of the standard rate band. Everything below it is charged at one rate and everything above at the other.

The USC adds three smaller steps of its own, at €12,012, at €28,700 and at €70,044. None of them coincides with the income tax threshold, which is why the combined marginal rate moves five times across a working salary range rather than once.

Add the USC exemption cliff at the bottom and the self-employed surcharge at €100,000, and the full picture is a scale that is simple in its headline and lumpy in practice.

The calculator computes both charges independently and reports the combination, which is the number that determines what an extra euro of salary is actually worth.

Questions

How much tax do I pay on €50,000 in Ireland?

€7,200 of income tax after €4,000 of credits, plus €1,033 of USC — €8,233 in all, an effective rate of 16.5%. PRSI is deducted on top and is not included here.

What is the standard rate cut-off point?

The income at which 20.0% stops and 40.0% begins: €44,000 for a single person and €53,000 for a married couple with one income, with more again for a single person with a qualifying child. It is a personal circumstance rather than a fixed figure.

How do Irish tax credits work?

They reduce the tax itself, not your income. A single employee has €2,000 of personal credit and €2,000 of employee credit — €4,000 together, which is exactly 20.0% of €20,000, and why a salary at that level produces no income tax at all.

What is the USC and do credits reduce it?

The Universal Social Charge is a separate progressive charge on gross income with its own four bands, and no, credits do not reduce it. On €20,000 the income tax is €0 and the USC is still €220.

What is the real Irish marginal rate?

At higher incomes it is 48.0% from income tax and USC together, before PRSI. Quoting 40.0% as the top rate understates what the next euro costs by eight points.

Is PRSI included?

No. It is a separate social insurance contribution deducted from wages alongside income tax and USC, and it is a real reduction in take-home pay. It is stated as excluded rather than folded in.
