Irish Tax and Payroll Glossary

A guide to the key terms you will encounter on your Irish payslip, tax return, and when using our salary calculator. Terms are listed in alphabetical order.

BIK (Benefit in Kind)
A Benefit in Kind is any non-cash benefit provided by your employer that has a monetary value, such as a company car, health insurance, or accommodation. BIK is treated as taxable income, meaning PAYE, USC, and PRSI are calculated on its value. The specific rules for valuing each type of benefit are set by Revenue.
Emergency Tax
Emergency tax is applied when your employer does not have your tax credits or Standard Rate Cut-Off Point on file, typically at the start of a new job. Under emergency tax, you receive basic tax credits for the first four weeks, after which all income is taxed at the higher rate with no credits. You can resolve this by registering your new job with Revenue through myAccount or the Revenue Online Service (ROS).
Gross Pay
Gross pay is your total earnings before any deductions are applied. It includes your basic salary, overtime payments, bonuses, commissions, and any other taxable income. This is the starting figure from which PAYE, USC, PRSI, and other deductions are calculated.
Marriage/Civil Partnership Relief
Married couples and civil partners in Ireland can choose between separate assessment, joint assessment, or assessment as a single person for tax purposes. Joint assessment typically provides the greatest benefit, as it allows unused tax credits and rate bands to be transferred between spouses. The specific tax credits and rate band available depend on the assessment option chosen.
Medical Insurance Relief
Tax relief is available on medical insurance premiums paid in Ireland. The relief is applied at source, meaning the insurance company reduces your premium by the value of the tax relief (currently at the standard rate of 20%). This relief applies to the gross premium, though a maximum limit applies per adult and per child covered under the policy.
Net Pay
Net pay, also known as take-home pay, is the amount you actually receive after all deductions have been subtracted from your gross pay. These deductions include PAYE income tax, Universal Social Charge, PRSI, and any voluntary deductions such as pension contributions or union fees. Net pay is the figure deposited into your bank account.
P45
A P45 is a certificate issued by your employer when you leave a job. It details your total pay, tax, USC, and PRSI deducted during your employment for that tax year. While the P45 process has been largely replaced by Revenue's real-time PAYE system, the concept remains relevant for understanding your cumulative tax position when changing jobs.
P60
A P60 is an end-of-year certificate that summarizes your total pay, tax deducted, USC, and PRSI contributions for the entire tax year. Under the modernized PAYE system, this information is now available through Revenue's Employment Detail Summary, which you can access via your myAccount portal online.
PAYE (Pay As You Earn)
PAYE is the system through which income tax is deducted from your wages by your employer on behalf of Revenue. The amount deducted depends on your gross pay, your tax credits, and the applicable tax rates. Ireland uses a two-rate system: income up to the Standard Rate Cut-Off Point is taxed at 20%, and income above that threshold is taxed at 40%.
PRSI (Pay Related Social Insurance)
PRSI is a social insurance contribution that funds state benefits such as the State Pension, Jobseeker's Benefit, and Illness Benefit. Most employees pay Class A PRSI at 4% of their gross income. Employers also make a PRSI contribution on your behalf. The rate and class of PRSI depend on your employment type and earnings level.
Revenue
Revenue, formally known as the Revenue Commissioners, is the Irish government body responsible for collecting taxes, duties, and related charges. Revenue administers the PAYE system, issues tax credits and certificates, and manages taxpayer records. Employees interact with Revenue through the myAccount online portal to manage their tax affairs.
Standard Rate Cut-Off Point
The Standard Rate Cut-Off Point (SRCOP) is the amount of income you can earn at the standard tax rate of 20% before the higher rate of 40% applies. The SRCOP varies depending on your personal circumstances, such as whether you are single, married with one income, or married with two incomes. Revenue sets the SRCOP each year in the national budget.
Tax Code
In the Irish tax system, your tax position is determined by your Revenue Payroll Notification (RPN), which communicates your tax credits, standard rate cut-off point, and USC rates to your employer. This ensures the correct amount of tax is deducted from each pay period. If your RPN is not available, your employer may apply emergency tax rates.
Tax Credits
Tax credits are amounts that reduce the total income tax you owe. Unlike tax deductions, which reduce your taxable income, credits are subtracted directly from your calculated tax liability. Common Irish tax credits include the Personal Tax Credit, Employee Tax Credit (PAYE Credit), and Home Carer Tax Credit. Revenue assigns your applicable credits through your RPN.
USC (Universal Social Charge)
The Universal Social Charge is a tax on gross income that is separate from PAYE income tax. USC uses a progressive rate structure with multiple bands - lower rates apply to initial portions of income, with higher rates applying as income increases. Certain individuals, such as those earning below a specific threshold, medical card holders, or people over 70 with income below a set limit, may qualify for reduced USC rates.

Frequently asked questions

What is the Standard Rate Cut-Off Point?
It is the amount of income taxed at twenty percent before the forty percent rate begins, set at €42,000 for a single person in 2026. Crossing it does not raise the tax on income already earned: only the excess is taxed at the higher rate. Married couples and single parents have higher cut-off points, which is why the same salary produces different take-home pay depending on status.
Cumulative Basis
The default method of calculating PAYE, under which each payslip recalculates tax on everything earned in the year to date and deducts what has already been paid. It is self-correcting: an overdeduction one month is refunded the next without any action. Starting a job late in the year gives access to the full year's credits against only a few months of income, which is why deductions then look unusually low.
Week 1 Basis
A non-cumulative method, applied when Revenue lacks the information to calculate cumulatively. Each pay period is treated in isolation with one period's credits, and no adjustment is made for earlier periods. It is not emergency tax, but it produces similarly high deductions with no obvious cause. It resolves once Revenue issues a cumulative RPN, usually after the employment record is corrected in myAccount.
Form 11 and Form 12
Form 11 is the self-assessment return, required of anyone with non-PAYE income above €5,000 in a year, and filed by the October deadline. Form 12 is the simpler return for PAYE taxpayers with small amounts of other income. The threshold concerns the filing obligation rather than the tax itself: the same income can be taxed either way, but only one route requires self-assessment.
Additional Voluntary Contribution
An AVC is an extra payment into an occupational pension scheme, above whatever the scheme itself requires. It attracts the same income tax relief as an ordinary contribution, within the same age-related limits, and can usually be started or stopped at will. AVCs are the standard route for anyone wanting to increase pension saving without changing employer or scheme.
Rent Tax Credit
A credit of up to €1,000 for a single person and €2,000 for a jointly assessed couple, available to tenants in private rented accommodation. It must be claimed rather than granted automatically, and it can be backdated for up to four years, which makes a first claim frequently worth several thousand euro. The tenancy generally has to be registered with the Residential Tenancies Board.
Standard Rate Cut-Off Point
The amount of income taxed at twenty percent before the forty percent rate applies, set at €42,000 for a single person in 2026 and higher for married couples and single parents. Only income above the threshold is taxed at the higher rate. It is shown on every payslip, usually divided by the number of pay periods, and an incorrect figure there is a common cause of overdeduction.
Revenue Payroll Notification
The instruction Revenue sends an employer setting out which tax credits and cut-off point to apply to a given employee. Without one, the employer must operate emergency tax. It is issued once an employment is registered, normally within a few working days, and it is updated automatically whenever credits change during the year.
Universal Social Charge
A charge on gross income introduced in 2011, levied across four bands and calculated before any pension deduction. Credits do not reduce it and pension relief does not apply to it, which makes it the least avoidable of the three deductions. Anyone earning €13,000 or less in the year is exempt entirely, and reduced rates apply to some medical card holders and those over seventy.
What is an RPN and why does it matter?
A Revenue Payroll Notification is the instruction Revenue sends your employer telling them which tax credits and cut-off point to apply. Without one, the employer must operate emergency tax, which deducts far more than is due. An RPN is issued once the employment is registered, usually within a few working days, and a missing one is the single most common cause of an unexpectedly small first payslip.
Cumulative Basis
The default method of calculating PAYE, under which each payslip recalculates tax on everything earned in the year to date and deducts what has already been paid. It is self-correcting: an overdeduction one month is refunded the next without any action. Starting a job late in the year gives access to the full year's credits against only a few months of income, which is why deductions then look unusually low.

Anyone earning €13,000 or less in the year is exempt entirely, and reduced rates apply to some medical card holders and those over seventy.
What is the difference between a tax credit and a relief?
A credit reduces the tax calculated, euro for euro, so a €1,875 credit cuts the bill by exactly that amount whatever your rate. A relief reduces the income on which tax is calculated, so its value depends on your marginal rate: €1,000 of pension relief is worth €400 at the higher rate and €200 at the standard rate. The distinction decides which is worth claiming first.

The default method of calculating PAYE, under which each payslip recalculates tax on everything earned in the year to date and deducts what has already been paid. It is self-correcting: an overdeduction one month is refunded the next without any action.

Anyone earning €13,000 or less in the year is exempt entirely, and reduced rates apply to some medical card holders and those over seventy.
What does emergency tax actually cost?
Under emergency basis, the employer applies a reduced cut-off point and, after four weeks, no tax credits at all, so deductions can exceed half of gross pay. Nothing is lost permanently: the overpayment is refunded through payroll once Revenue issues the correct RPN, usually within one or two pay cycles. The cost is cash flow rather than tax, but at the start of a job that distinction matters.
Cumulative Basis
The default method of calculating PAYE, under which each payslip recalculates tax on everything earned in the year to date and deducts what has already been paid. It is self-correcting: an overdeduction one month is refunded the next without any action. Starting a job late in the year gives access to the full year's credits against only a few months of income, which is why deductions then look unusually low.

What is the USC exemption threshold?
Anyone whose total income for the year is €13,000 or less pays no Universal Social Charge at all. Above that figure, USC applies to the whole income rather than only the excess, which makes the threshold a cliff rather than a slope. Reduced rates also apply to medical card holders under a certain income and to people aged seventy and over.

What is Class A PRSI?
Class A is the contribution class covering most employees in the private sector and gives access to the widest range of benefits, including the State Pension, Jobseeker's Benefit and Illness Benefit. It is charged at four percent of gross earnings with no upper limit, and nothing is due where weekly earnings are €352 or less. Employers pay a further contribution on top, at one of two rates.
