Staying on top of tax deadlines in Ireland can feel overwhelming, especially if you’re new to running a business or filing your own self-assessed tax return. The good news? Once you know the key dates and what each one means, the process becomes far less stressful.

​

At Bond & Co Chartered Accountants, we work with individuals, landlords, sole traders, and companies across Ireland to take the stress out of tax. This guide will walk you through the most important Irish tax deadlines -  and show you how working with us can save you time, money, and headaches.

​

Why Tax Deadlines Matter

​

Missing a tax deadline in Ireland doesn’t just mean extra stress - it can also mean:

• Late filing penalties (a percentage of your tax bill added on top).

• Interest charges on unpaid tax.

• Increased risk of a Revenue audit.

• Cash flow pressure if you suddenly need to pay a lump sum at short notice.

​

The easiest way to avoid all of this is to let Bond & Co manage your deadlines for you. We’ll track every date, file on time, and make sure you never get caught out. Talk to our team today.

​

Personal Tax Deadlines (PAYE & Self-Employed)

​

1. PAYE Employees

​

If you’re a PAYE employee, your employer handles your taxes. But you may still want to:

• Claim tax credits (medical expenses, tuition fees, work-from-home).

• File if you earn extra income (rental property, freelance work, investments).

​

If you’re unsure what you can claim, we can review your situation and maximise your tax refund.

​

2. Self-Employed, Sole Traders & Landlords

​

For sole traders and landlords, the 31 October deadline is critical. You must file your Form 11 Income Tax Return and pay any balance due. Filing via ROS usually extends the deadline to mid-November.

But here’s the catch: preparing accounts, calculating expenses, and paying preliminary tax can be complex.

​

At Bond & Co, we work with hundreds of self-employed people to handle everything - from bookkeeping to filing your return. That way, you can focus on running your business, not Revenue paperwork.

​

VAT Deadlines

​

VAT is one of the trickiest areas for small businesses. Returns are due bi-monthly (with ROS extensions to the 23rd). Mistakes can lead to penalties and even audits.

Our VAT service means:

• We register you correctly.

• File on time, every time.

• Ensure you’re reclaiming all input VAT you’re entitled to.

​

Corporation Tax Deadlines

​

For limited companies, deadlines depend on your accounting year end.

• Form CT1 return: due nine months after year end.

• Preliminary tax: due in month 11.

 

Running a company is complex enough without chasing tax deadlines. Our team provides full corporate compliance services, so you never have to worry about missing a date.

​

Employer (Payroll) Deadlines

​

Since PAYE modernisation, employers must report payroll in real time. Payments to Revenue are due by the 14th of the following month.

 

Payroll mistakes are costly and time-consuming. Our payroll bureau handles everything securely and accurately, ensuring your staff and Revenue are always paid on time.

​

Capital Taxes (CGT & CAT)

​

If you sell property, shares, or receive an inheritance, you may face Capital Gains Tax (CGT) or Capital Acquisitions Tax (CAT). These have strict deadlines (15 December, 31 January, and 31 October depending on timing).

 

Many clients come to us after receiving a gift or inheritance, unsure how much tax is due. We provide clear, practical advice so you only pay what you owe - nothing more.
