The world of self-employment is an exciting and complex one. It allows you to follow your passions, enjoy greater flexibility, and we think best of all, experience the freedom of working for yourself. But being self-employed also means you’re responsible for managing your own tax affairs.
In Ireland, the main deadline to file your self-assessment tax return is 31st October 2025. However, if you’re filing and paying online through Revenue’s ROS system, you have until the extended deadline of 14th November 2025 (this date is subject to final confirmation by Revenue each year, so always double-check on their official website).
If you want to avoid penalties, now is the time to act. Here’s what you need to know to keep your financial affairs in order.
the basics
Registering as Self-Employed
If you’ve recently started working for yourself, you must register with Revenue. Failing to register on time can lead to penalties.
Income Tax
Like PAYE employees, self-employed individuals must pay income tax—but you’re responsible for calculating and paying it yourself. This is done annually using Revenue’s Pay and File system.
Key Online Tax Deadlines (2025)
Ireland’s tax system continues to shift online. Here are the key dates to watch:
Preliminary Tax
If your annual income exceeds a certain level, you’ll be expected to make a Preliminary Tax payment—essentially paying tax for the current year based on last year’s earnings.
Due: 31st October 2025 (or 14th November if filing online).
Pay and File
This is your annual tax return where you:
- Submit your Form 11 (self-assessment),
- Pay your balance for 2024,
- And make your Preliminary Tax payment for 2025.
Due: 31st October 2025 or 14th November 2025 online.

Remember!
Being self-employed means you’re responsible for your own financial obligations, but it doesn’t mean you have to do it all alone. Staying organised and keeping accurate records throughout the year is the best way to avoid unexpected bills or penalties.
If you’re unsure where to start, speaking to a trusted financial advisor or tax professional can help you stay compliant and focused on running your business.
