Tax and starting work - PAYE


Most employees pay tax through the PAYE (Pay As You Earn) system. This means that your employer deducts the tax you owe directly from your wages, and pays this tax directly to Revenue. Revenue collect taxes from citizens on behalf of the Irish Government.

You will also pay PRSI and the Universal Social Charge on your income.

Starting work

It is important to ensure that your tax is dealt with properly from the start and that your new employer deducts the right amount of tax from your pay. To ensure that this happens, you will need to do two things:

  • Give your employer your Personal Public Service Number (PPS number). This number is your unique personal identification number for public services. Your employer will notify Revenue of your start date. This will create a new employment record for you and let your new employer access up-to-date tax credits and tax rate bands for you. Read more about how to get a PPS number in 'How to apply' below.
  • Register the details of your new job with Revenue’s Jobs and Pensions online service in myAccount – see 'How to apply' below.

To ensure that your employer and the tax office have time to have everything sorted out before your first payday, it is advisable to do all this as soon as you accept an offer of a job (even for part-time or holiday employment).

Tax credits

Tax credits reduce the amount of income tax that you have to pay. Your gross tax is calculated depending on your income. Tax credits are then deducted from the gross tax to give the amount of tax that you have to pay.

Tax credits consist of various credits and reliefs which you may be able to claim, depending on your circumstances. Every individual can claim a personal tax credit for example, and you can also claim relief for items such as the One Parent Family Credit.

When you have registered the details of your new job, Revenue will send your employer a tax credit certificate showing the tax credits that your employer deducts from your tax bill. You can view your tax credit certificate and claim any additional tax credits you may be due through Revenue's PAYE Services. You access PAYE Services through Revenue's myAccount Service.

Details of all the main tax allowances and reliefs are given on the explanatory leaflet available from your tax office or online from

What do I have to pay tax on?

Tax is payable on earnings of all kinds that result from your employment (including for example, bonuses, overtime, non-cash pay or benefit-in-kind such as the use of company car, tips or Christmas boxes. You do not pay tax on: scholarship income, interest from savings certificates, savings bonds and national instalment savings schemes, and payments to approved pension schemes.

Pay that you receive through working extra hours (overtime) or bonuses, is included as part of your taxable pay for that week or month. You do not get any additional tax-free allowances against these additional earnings.

Emergency tax

If your new employer does not get your Revenue Payroll Notification (RPN), they will have to emergency tax your income. (An RPN replaces the current P2C and is available in real-time to employers.)

In most cases your employer will get your RPN. However, they will not receive it if:

  • You don’t give them your Personal Public Service Number
  • You are not registered for Pay As You Earn (PAYE). (You will automatically be registered for PAYE when you register a job or pension using the Jobs and Pensions service in myAccount).

If your employer has not received:

  • Personal Public Service Number from you
  • Revenue Payroll Notification from Revenue

Note: You must register for Pay As You Earn (PAYE) – See ‘Starting Work’ above.

If your employer does not get this information they must deduct tax on an emergency basis when paying your wages or salary. This means that they will give you a temporary tax credit for the first month of employment but tax deductions are increased progressively from the second month onwards. Being taxed on an emergency means that after 4 weeks no tax credits are given, and tax is paid at the higher rate from week 9, regardless of the level of pay.Details of emergency tax rates are available on the Revenue website.

Income tax bands

Income tax bands will determine the rate of tax you pay on your income or salary. Read more about how your tax is calculated here.

More detailed information regarding tax credits and reliefs is available from your tax office.

Starting a second job

If you choose to take on a second job, you can allocate your tax credits and rate band between your employers. Each employer will then receive a Revenue Payroll Notification which instructs them on the correct deductions to make for you. See Revenue's document on what to do if you get a second job.

How to apply
