Your Tax Obligations in Ireland: A Simple Guide

Everyone who earns income in Ireland has tax obligations, but they are easy to overlook until a penalty arrives. In short, you must register for the right taxes, file your returns on time, pay what you owe and keep records for six years.

Register for the right taxes

  • Employees and self-employed people register with Revenue for a Personal Public Service (PPS) number-based tax record.
  • Employers register for PAYE/PRSI.
  • Businesses register for VAT once they exceed the €40,000 (services) or €80,000 (goods) thresholds.
  • Companies register for Corporation Tax on incorporation.

File your returns on time

  • Self-employed people file an income tax return (Form 11) each year.
  • Companies file a Corporation Tax return (Form CT1) each year.
  • Employers file PAYE returns on each payroll run.
  • VAT-registered businesses file VAT returns, usually every two months.

Pay what you owe

Paying late attracts interest and can lead to penalties. Setting up direct debits for VAT and PAYE is one of the easiest ways to avoid missing payments. For income tax, preliminary tax is generally due by 31 October (or mid-November when paying online).

Keep records for six years

You must keep the records behind your returns — invoices, receipts, bank statements and books — for six years. Revenue can ask to see them, and having them organised makes any enquiry far less painful.

Frequently asked questions

What happens if I miss a filing deadline?

You can face penalties and interest, and late filing can also affect reliefs such as audit exemption for companies.

How long do I need to keep tax records?

Six years, in case Revenue asks to review them.

When is preliminary tax due?

Generally by 31 October each year, or mid-November if you file and pay online through ROS.
