Emergency Tax Ireland 

Rates, refunds and employer rules

Emergency tax applies when an employer cannot retrieve a valid Revenue Payroll Notification (RPN) for an employee. It is not a fine or a punishment. It is the fallback tax basis used until Revenue can provide the tax credits, rate band and USC instructions needed to run that employment correctly.

For an employee, the result can be a much smaller payslip than expected. For an employer, the rule is straightforward: if no valid RPN is available, you cannot estimate the employee’s normal tax position or add credits manually. You must use the emergency basis and keep checking for an RPN.

The amount deducted depends on whether the employee has supplied a PPSN and, where a PPSN is available, how long the emergency basis has been in use. Once the underlying issue is fixed, a cumulative RPN can correct the year-to-date Income Tax and USC position through payroll.

Emergency tax in one minute No valid RPN means emergency basis. No PPSN means 40% Income Tax on all pay from the first payment, plus 8% USC. With a PPSN, a temporary standard-rate band applies for a short initial period before the band falls to zero. PRSI continues under the employee’s normal PRSI class.

What emergency tax means

An RPN tells the employer which Income Tax credits, standard rate band and USC bands to use for a particular employment. Emergency Tax applies when that valid RPN is not available.

That distinction matters. Emergency tax is not the same as Week 1 or Month 1 basis. Week 1 is a valid RPN on a non-cumulative basis. Emergency tax is used because there is no valid RPN to operate.

Under the emergency basis, the employer still runs payroll normally in every other respect. The employee is paid, the payroll submission is filed on time, PRSI is calculated using the correct class, and the employer continues to request an RPN.

Key terms

Why emergency tax happens

The immediate cause is always the same: there is no valid RPN for the employer to use. The reason behind that can be very different, and the fix depends on which situation you are dealing with.

First job in Ireland

If this is the employee’s first job in the State, the employee must register that first employment through Revenue myAccount. The employer cannot register the first employment on the employee’s behalf.

The employee needs a PPSN, access to myAccount, the employer’s Tax Registration Number, the start date and the pay frequency. Once the job is registered, Revenue makes an RPN available to the employer. Revenue states that the employee should be able to view the Tax Credit Certificate within two working days.

This rule catches out new arrivals, students starting work for the first time and people who assume that giving a PPSN to HR automatically registers the employment. It does not. The first employment still has to be registered by the employee.

Changing jobs or starting an additional job

For a second or later employment, the employer registers the employment through ROS or payroll software by requesting an RPN. The employee does not need to repeat the first-job registration process.

If the employer has the correct PPSN but no RPN is returned, check that the commencement details are correct and that the employment has been created properly. Until the RPN is available, use the emergency basis.

No PPSN, or the wrong PPSN

Without a PPSN, Revenue cannot link the employee to the right tax record. The no-PPSN emergency rules apply from the first payment.

The payroll submission still has to be made. Where the PPSN is unavailable, report the employee’s name, address and date of birth and use a consistent Employer Reference on every submission until the PPSN is available.

Do not change that Employer Reference casually. Revenue uses it to link earlier payslips once the PPSN is supplied. A mismatch can leave payslips unlinked from the employee’s record and can affect the pay, tax and PRSI information visible to the employee.

A second job taxed at 40% is not automatically emergency tax

A valid RPN can legitimately show no tax credits and no standard rate band for a second job. Revenue allows employees to split tax credits and rate bands between jobs, but an employee may leave all of them with a main employment.

If that happens, the second employer can deduct Income Tax at 40% from the first euro. The payslip may look like emergency tax, but it is not. The employer has a valid RPN and is following it.

Splitting credits and rate bands between jobs changes where tax is deducted during the year. It does not change the employee’s total annual Income Tax liability.

Start of a new tax year

A 2025 RPN cannot be used for a payment made in 2026. Revenue made 2026 RPNs available from early December 2025 and employers should request them for all employees before the first 2026 payroll run.

If no current-year RPN is available, emergency basis applies. This is why a January RPN refresh belongs on the payroll checklist every year, even where nothing has changed in the employee’s job.

Emergency tax rates for 2026

The figures below come from Revenue’s Emergency Basis of Tax Deduction 2026. There are no tax credits under the emergency basis. Emergency USC is 8% on all income.

If the employee has not provided a PPSN

Example: Helena earns €800 a week and has not provided her PPSN. Income Tax is €320 and emergency USC is €64, before normal PRSI is applied. Her PAYE and USC deductions alone are €384.

If the employee has provided a PPSN

A temporary standard-rate band applies for a limited number of pay periods. There are still no tax credits. Once that initial period ends, the emergency band falls to zero and all pay is taxed at 40%.

Monthly payroll moves to 40% quickly A monthly-paid employee with a PPSN gets the emergency standard-rate band in month 1 only. From month 2, the band is zero. Do not apply the weekly four-week rule to a monthly payroll.

Why the deduction can feel severe

A single PAYE employee with the standard 2026 Personal Tax Credit and Employee Tax Credit has annual credits of €4,000. That is roughly €76.92 a week of Income Tax reduction. Those credits disappear under emergency tax.

The employee also pays 8% emergency USC instead of the normal progressive USC bands. Once the emergency standard-rate band disappears, Income Tax is 40% from the first euro as well. That combination explains why the drop in net pay can be sharp.

PRSI during emergency tax

PRSI has no emergency rate. Apply the employee’s normal PRSI class and the current Class A PRSI rates and thresholds where Class A applies.

For a Class A employee earning more than €552 a week, the employee rate is 4.20% up to 30 September 2026 and 4.35% from 1 October 2026. The lower earnings bands and tapered employee PRSI credit still apply where relevant.

If a PRSI classification decision identifies an error in the current tax year, the employer should correct the payroll record before year-end. Where a refund is needed after the tax year has ended, the employee or employer can use the Department of Social Protection PRSI refund process.

That is different from an emergency Income Tax and USC refund. PAYE and USC overdeductions can be corrected automatically through payroll when a cumulative RPN arrives. PRSI follows its own correction and refund rules.

What employers must do when no RPN is available

Emergency tax is not optional. The employer cannot decide to use ‘normal’ credits because the employee is known to be single, has shown an old Tax Credit Certificate or says what their credits should be. Operate the RPN when one exists. Use emergency basis when it does not.

Employers cannot waive emergency tax

The employer-side rule is explicit: where no RPN is available, emergency basis must be applied.

Trying to protect the employee’s take-home pay by adding credits manually creates a payroll compliance problem. The right response is to fix the registration or PPSN issue quickly, retrieve the RPN and let the cumulative payroll calculation make the correction.

Emergency tax is continuous

Revenue’s continuous emergency-tax rule counts calendar weeks from the date the employee first started with that employer, including weeks in which the employee did not actually work.

Example: an employee started five weeks ago but worked only three of those weeks. If emergency basis still applies in week 5, the weekly emergency band is already zero. All pay is taxed at 40%, even though the employee has only received three working weeks of pay.

January is a specific control point

At the start of the tax year, request current-year RPNs before running payroll. Do not carry a previous-year RPN forward because the employee’s tax credits, rate band or USC position may have changed.

This is a small payroll control with a large practical effect. A missed RPN refresh can put an otherwise correctly registered employee onto emergency basis unnecessarily.

How to stop emergency tax

The fix is usually administrative, but the correct person has to take the correct step. First jobs are employee-led. Later employments are employer-led.

First job in Ireland: employee steps

1. Get a PPSN from the Department of Social Protection if one has not already been issued.

2. Register for Revenue myAccount.

3. Open PAYE Services and select Add Job or Pension Details.

4. Enter the employer’s Tax Registration Number, the employment start date and the pay frequency.

5. Tell payroll once registration is complete so the employer can retrieve the RPN before the next payroll run.

Revenue’s current Add a job or a pension service is specifically for a first job or private pension. Subsequent jobs are registered by the employer.

Changing jobs: employer steps

1. Collect the employee’s PPSN and check it has been entered accurately in payroll.

2. Register the employment through ROS or the payroll software RPN process.

3. Request the RPN before processing the first payroll.

4. If no RPN is returned, check the commencement details and PPSN. Apply emergency basis until the RPN becomes available.

If the employee has no PPSN yet

A new arrival or another employee without a PPSN should apply through the Department of Social Protection. The employer should not delay paying the employee while waiting for the PPSN, but the no-PPSN emergency rates must be used.

Keep the employee’s name, address, date of birth and Employer Reference consistent across payroll submissions. When the PPSN arrives, add it using the same Employer Reference so the earlier payroll records can be linked.

How long does the process take?

Registration can be completed online, but do not promise an exact RPN processing time to an employee. The reliable published timing is that a first-job employee should be able to view the Tax Credit Certificate within two working days after registration.

How emergency tax refunds work

Once an RPN is available, the refund route depends on whether it is cumulative or Week 1 / Month 1. Revenue’s emergency tax refund guidance makes that distinction clear.

Cumulative RPN: refund through payroll

With a cumulative RPN, the employer recalculates the employee’s Income Tax and USC from the start of the year using the correct credits, rate band and USC bands. Any overpayment is refunded through payroll on the next payday.

If the RPN is retrieved before the current payroll run is processed, the correction can appear on that payslip. If the payroll is already complete, it will normally appear on the following payday.

The refund is not an employer goodwill payment and should not be made as an off-payroll cash adjustment. It comes from the cumulative PAYE and USC calculation.

Week 1 or Month 1 RPN: no retrospective payroll refund yet

A Week 1 or Month 1 RPN is valid but non-cumulative. While that basis remains in force, the employer cannot use it to refund Income Tax or USC overpaid in earlier periods.

The employee should contact Revenue through MyEnquiries to find out why the Week 1 basis applies. Revenue may use Week 1 where there is not enough information about earlier employments or current-year earnings, where the employee has recently arrived from abroad, where there is a large reduction in credits, where credits are being moved between spouses or civil partners, or where the employee does not want the new employer to see earlier pay and tax details.

If Revenue later issues a cumulative RPN, the employer can then calculate the year-to-date position and refund any amount due. If Week 1 remains in place at year-end, the employee should submit an Income Tax Return through myAccount.

If the employee moves to a new job

An employee can leave before the old employer has had a chance to process the emergency-tax refund. If the employee moves to another job in the same tax year, the new employer can make the refund when it receives a cumulative RPN containing the relevant year-to-date position.

If the employee becomes unemployed

If there is no new employer to process the refund, the employee can claim an Income Tax and USC repayment directly from Revenue through myAccount.

Previous tax years

Emergency tax from a closed tax year is dealt with by filing an Income Tax Return for that year. In 2026, the four-year claim window covers 2022, 2023, 2024 and 2025. A claim for 2022 must be submitted by 31 December 2026.

1. Sign in to myAccount.

2. Open Review your tax for the previous 4 years under PAYE Services.

3. Select the relevant year and request a Statement of Liability.

4. Complete the Income Tax Return for that year.

5. Revenue reviews the year and pays any refund due directly to the employee.

Why a refund may not appear when expected

If an employee says they registered but the refund is not on the payslip, check the RPN rather than guessing. Two common causes are a Week 1 RPN, which does not allow the retrospective correction, or an updated cumulative RPN that was issued after payroll had already been processed.

Multiple active jobs, changes in allowances and residency issues can also delay a Revenue refund review. Those are employee tax-record issues rather than payroll calculation choices.

Emergency tax on private pensions

Emergency tax can also apply to a non-State pension where the pension provider cannot retrieve an RPN. This includes pensions paid by a former employer, a pension provider or the provider of a deceased spouse or civil partner. The pension provider must use emergency basis if no RPN is available.

The pensioner can give the PPSN to the pension provider so it can request an RPN, or add the pension through myAccount under Add Job or Pension Details. Once the provider has the RPN, it uses that instruction to calculate Income Tax, USC and any LPT deduction that applies.

If a cumulative RPN is issued, the pension provider, not a former employer, is the party that recalculates the pension deductions and makes any payroll refund due.

Worked examples

These examples are fictional. The normal comparison assumes a single PAYE employee earning €900 a week, a €44,000 standard-rate band, a €2,000 Single Person Tax Credit, a €2,000 Employee Tax Credit, standard 2026 USC bands and Class A PRSI at 4.20% for a pay date before 1 October 2026. Individual positions can differ.

PPSN provided, week 1

The emergency Income Tax uses the 2026 weekly emergency band of €846.16. The normal USC comparison uses the 2026 standard USC bands.

Five weekly paydays before a cumulative RPN arrives

Using the same assumptions, the additional PAYE and USC deduction is about €130.90 in each of weeks 1 to 4. In week 5 the emergency band is zero, so the additional deduction rises to about €300.14.

Estimated PAYE and USC overdeduction over the first five weeks is therefore about €823.76. If the employer retrieves a cumulative RPN before week 6 payroll, the year-to-date calculation determines the actual refund due and pays it through payroll on that payday.

Why this example is useful The fifth week changes the scale of the deduction. It is not simply another week at the week 1 rate. The emergency standard-rate band has disappeared, so all weekly pay is now taxed at 40% before the 8% emergency USC is added.

Monthly-paid employee with a PPSN

Take a monthly-paid employee earning €4,500. In month 1, Income Tax under emergency basis is approximately €1,066.67, before emergency USC of €360.00. If no RPN is available in month 2, the emergency band is zero and Income Tax rises to €1,800.00, again before 8% USC.

This is why employers should not describe emergency tax to monthly-paid staff using the weekly ‘four weeks’ shorthand. The monthly band lasts for one monthly payday only.

Four situations payroll teams should recognise

First job, then cumulative correction

Aoife starts her first job in Ireland and gives payroll a PPSN, but she has not registered the employment in myAccount. Payroll cannot retrieve an RPN, so emergency basis applies. She registers after the third payday. Payroll retrieves a cumulative RPN before the fourth run and the overpaid Income Tax and USC are corrected through that payroll.

The employer did not need to estimate Aoife’s credits. The correct fix was registration, RPN retrieval and cumulative payroll.

Week 1 RPN after emergency tax

Patrick changes jobs. The new employer initially has no RPN, so emergency basis applies. An RPN then arrives on Week 1 basis. Payroll switches to Week 1 immediately but cannot refund the earlier overdeduction while that non-cumulative basis remains in force.

Patrick contacts Revenue through MyEnquiries. Once Revenue has enough information, it issues a cumulative RPN. Payroll then recalculates the year-to-date position and pays the refund due on the next payday.

Second job at 40% with a valid RPN

Sarah has a main job and starts weekend work. The weekend employer receives an RPN with zero credits and zero standard rate band because Sarah has left all of her credits and band with the main employment. The weekend wages are taxed at 40%.

That is not emergency tax. Sarah can leave the allocation as it is or change the split in myAccount. The employer should not override the valid RPN.

January payroll using the wrong year’s RPN

A payroll team prepares the first January 2026 run using cached 2025 RPN information. That is not valid for a 2026 pay date. The team should retrieve 2026 RPNs before the run and operate the current-year figures. Where no 2026 RPN is available for an employee, emergency basis applies.

For the wider RPN and payroll submission controls, see the PAYE Modernisation Ireland guide.

Employer emergency tax checklist

• Collect the PPSN before the first payroll run wherever possible.
• Ask whether this is the employee’s first job in Ireland. The registration route is different.
• For a first job, give the employee the Tax Registration Number, start date and pay frequency needed for myAccount registration.
• Register subsequent employments promptly and retrieve the RPN before payroll.
• Never apply tax credits or a normal rate band without a valid RPN.
• Use the correct 2026 emergency band for the employee’s actual pay frequency.
• Remember that emergency USC is 8% on all income.
• Apply normal PRSI class rules, including the 1 October 2026 rate change where relevant.
• Keep the Employer Reference unchanged on payroll submissions without a PPSN.
• Retrieve a fresh RPN before each payroll run.
• When a cumulative RPN arrives, process any Income Tax and USC refund due through payroll.
• Refresh RPNs for the new tax year before the first January payroll.

Emergency tax FAQs

Next payroll question Once an RPN is available, the credits and rate bands on that RPN determine the normal PAYE calculation. See the Irish Tax Credits and Reliefs 2026 guide for how those amounts work.
