All You Need to Know About the Tax Return Deadline in Ireland

Tax season can be a hectic time for both individuals and businesses in Ireland. For accounting firms, it’s a crucial period marked by stringent deadlines and increased workload.

In this blog, we’ll delve into all the essential information you need to know about the tax return deadline in Ireland. This comprehensive guide is tailored specifically for accounting firms, providing you with the knowledge and strategies to navigate this busy season efficiently.

Understanding the Irish Tax Year

Before we dive into the details of the tax return deadline, let’s first understand the basics of the Irish tax year. In Ireland, the tax year runs from January 1st to December 31st. This means that most tax returns cover income earned and expenses incurred during this calendar year.

Different Tax Deadlines for Different Taxpayers

One of the critical factors to consider when dealing with income tax return Ireland is that different taxpayers have different deadlines. The main categories are:

  • Self-Assessed Individuals: Self-assessed individuals, including self-employed individuals and proprietary directors, have a deadline of October 31st following the end of the tax year to file their tax return. For instance, for the tax year ending on December 31, 2023, the deadline to file a tax return is October 31, 2024.
  • Companies: Limited companies in Ireland have a different deadline. They must file their corporation tax return nine months after their accounting period ends. For example, if a company’s accounting period ends on December 31, 2023, the corporation tax return is due by September 30, 2024.
  • Employers: Employers must meet various deadlines throughout the year, including submitting payroll taxes and annual returns. The most common payroll taxes are Pay As You Earn (PAYE) and Universal Social Charge (USC). These taxes must be submitted and paid to the Revenue Commissioners on a monthly or quarterly basis.
  • VAT Returns: For Value Added Tax (VAT) returns, the deadlines vary depending on the filing method. Electronic filing typically has a later deadline, while paper filing has an earlier one. Accounting firms need to keep track of these deadlines for their clients.

Penalties for Late Filing

Meeting tax deadlines is paramount to avoid penalties and interest charges when filing a tax return Ireland. Late filing can result in significant financial consequences, which accounting firms must emphasise to their clients. For instance:

  • Self-assessed individuals who miss the October 31st deadline face late filing penalties and daily interest charges.
  • Companies that fail to submit their corporation tax returns on time will also incur penalties.
  • Employers who miss payroll tax deadlines may face penalties and interest charges.

Never miss a deadline hereafter. Outsource tax season support to qualified experts and make this tax season a roaring success for your firm. Ready to get started?

Extensions and Deferrals

In some cases, taxpayers may be eligible for extensions or deferrals of their tax deadlines. This is particularly important for accounting firms to be aware of, as they can help their clients navigate these options. Extensions and deferrals may be granted under specific circumstances, such as illness or extreme financial hardship.

Electronic Filing and Revenue Online Service (ROS)

The Revenue Commissioners strongly encourage electronic filing through the Revenue Online Service (ROS). ROS offers a secure and efficient way to file a tax return in Ireland and make payments online. It also provides access to important tax information and correspondence from the Revenue Commissioners.

Accounting firms should ensure they are registered for ROS and are proficient in using the platform. It simplifies the tax filing process and reduces the likelihood of errors.

Preparing for the Tax Season

To prepare for the tax season effectively, accounting firms should:

  • Start Early: Begin gathering necessary financial documents well in advance of the filing deadline. This allows ample time for reviewing, organising, and addressing any issues that may arise.
  • Communicate with Clients: Maintain open lines of communication with clients throughout the year, reminding them of important deadlines and providing guidance on record-keeping.
  • Use Accounting Software: Invest in reliable accounting software that streamlines the tax preparation process, reduces errors, and enhances efficiency.
  • Stay Informed: Keep up-to-date with changes in tax laws and regulations in Ireland. Tax legislation can change, so being informed is crucial to providing accurate advice.
  • Seek Professional Development: Encourage staff members to participate in training and professional development programs to stay current with industry best practices.
  • Outsource tax returns: The busy period during the tax season can often be overwhelming as accounting firms are flooded with last-minute requests. A foolproof strategy to manage the extra workload without burning out your team is by outsourcing income tax return Ireland.


Navigating the tax return deadline in Ireland can be a challenging task, but it’s a fundamental aspect of the work performed by accounting firms. By understanding the various deadlines, penalties for late filing, and the importance of electronic filing, accounting firms can better serve their clients and ensure compliance with tax regulations.

Preparation and communication are key elements in managing this busy season efficiently. As tax laws evolve, staying informed and adapting to changes will be essential for accounting firms to continue providing excellent service to their clients in Ireland.
