Ireland's Tax Credits System

There is no Irish personal allowance. Tax is charged from the first euro and then reduced by credits, which sounds worse and works out much the same at the bottom and rather differently in the middle.

Ireland's Tax Credits System

Most European systems give you a slice of income free of tax and then start charging. Ireland does not. Income tax is charged at 20% from the first euro up to the standard rate band, which ends at 44,000 euros for a single person, and at 40% above it.

What makes the system liveable at lower incomes is the credit structure. Tax calculated on the bands is then reduced by a set of credits, and the two largest apply to almost every employee automatically.

The two automatic credits

  • The personal tax credit, currently 1,875 euros for a single person and double that for a jointly assessed married couple.
  • The employee tax credit, also 1,875 euros, available to anyone taxed under PAYE. The self-employed have an equivalent earned income credit instead.
  • Together they remove 3,750 euros of tax, which at the 20% rate is equivalent to earning roughly 18,750 euros before any income tax is due.
  • Credits are not refundable. They reduce tax to zero and no further, so someone with very low earnings cannot receive the unused portion.

That equivalence is the useful way to think about it. The effect is similar to a tax free allowance of around eighteen thousand euros, delivered by a different mechanism.

The credits nobody claims

Alongside the automatic ones sits a long list of credits and reliefs that require a claim. Revenue does not apply them unprompted, and four years of backdating is permitted.

Credit or relief Who it is for Comment
Rent tax credit Tenants in private rented accommodation Introduced recently and heavily underclaimed
Medical expenses relief Anyone with unreimbursed medical costs Relief at the standard rate, at the higher rate for nursing home fees
Single person child carer credit A single parent with a qualifying child Substantial, and only one parent may claim it
Home carer tax credit A married couple where one spouse cares for a dependent at home Requires joint assessment
Remote working relief Employees working from home A proportion of electricity, heating and broadband
Tuition fees relief Third level fees paid for yourself or a dependent Subject to a disregard amount
Flat rate expenses Specific occupations with agreed amounts Applied automatically for some trades, claimed for others

The flat rate expense schedule is worth a mention. Revenue publishes agreed deductions for dozens of occupations, from nurses and teachers to shop assistants and engineers. Many are applied automatically, but a change of occupation frequently leaves the wrong one in place.

The rate band is the other half

Credits reduce the tax. The standard rate band decides how much of your income is taxed at 20% rather than 40%, and it varies by circumstance.

  1. A single person has a band ending at 44,000 euros.
  2. A married couple with one income has an increased band, which is one of the larger advantages of joint assessment.
  3. A married couple with two incomes has a further increase, capped by the lower earner's income, so the transferable portion is limited.
  4. A single parent qualifying for the single person child carer credit receives an increased band as well as the credit.

Joint assessment is the default for married couples and civil partners once elected, and it is almost always at least as good as separate treatment. Couples who never elected are frequently losing money, and the election can be backdated.

What sits alongside income tax

Two further charges apply and neither is reduced by tax credits. The Universal Social Charge is a separate progressive levy on gross income, and PRSI is charged at 4.1% above a weekly threshold. Together they are the reason Irish take-home pay at middle incomes is lower than the income tax figures alone suggest.

The USC is covered in the USC explained, and PRSI in PRSI classes.

How to check your position

Your tax credit certificate is available in the Revenue online service and lists every credit currently applied and how the rate band is allocated between employments. It takes a few minutes to read and it is the single document that determines your monthly deduction.

If it does not list a credit you are entitled to, add it. The change flows to your employer automatically and takes effect from the next payroll run.

Credits reduce tax rather than income, so the value is the same whatever you earn. See the combined effect on the Ireland Salary Calculator.
