Your Quick-Start Guide to Ireland & EU Tax Compliance: Do This First

1. Audit Your Irish Payroll for Mandatory Auto-Enrolment

As of January 1, 2026, the landscape for Irish employers changed forever. The Mandatory Auto-Enrolment pension scheme is now in full effect. If you have employees aged between 23 and 60 who earn over €20,000 per year and are not already in a qualifying pension scheme, you must have them enrolled.

Do this first:

• Verify Employee Eligibility: Audit your payroll data to identify every staff member hitting the age and wage thresholds.
• Update Your Systems: Ensure your payroll software is configured to handle the new deduction rates.
• Communicate: Legally, you must inform your employees of their enrollment status.

Failing to comply doesn’t just result in unhappy staff; the Pensions Authority is actively issuing penalties for non-compliance and requiring retrospective contributions. If you find this transition overwhelming, payroll processing services ensure that every deduction is calculated and filed correctly.

2. Register for CARF (If Applicable) Immediately

The Crypto-Asset Reporting Framework (CARF) is no longer a “future concern.” We are in the critical window for registration. If your business qualifies as a Reporting Crypto-Asset Service Provider (RCASP), which includes many modern ecommerce entities that accept or trade in digital assets, you have a deadline of December 31, 2026, to register with Revenue.

However, the “Do This First” part is the collection of customer self-certifications. You cannot wait until the end of the year to start tracking this data. You need to upgrade your IT and accounting workflows now to track cryptocurrency transactions for the first major reporting deadline on May 31, 2027.

3. Claim the Enhanced 35% R&D Tax Credit

For businesses involved in innovation, whether you are developing new software, food products, or manufacturing processes, the 2026 fiscal year offers a massive opportunity. The Research and Development (R&D) tax credit has been enhanced to a 35% rate (up from 30%).

Furthermore, the first-year payment threshold has increased to €87,500. This is direct cash flow back into your business.

The catch: If you are a first-time claimant, you must provide a 90-day pre-filing notification to Revenue. If you are planning to claim this in your year-end accounts, you need to establish your record-keeping protocols today. Detailed time-tracking for employees (keeping in mind the 95% threshold rule) is non-negotiable. Managing these records is a core part of effective cash flow management and ensures you don’t leave money on the table.

4. Validate Your EU VAT Registrations

For cross-border sellers, the EU VAT landscape remains complex. If you are selling into Germany, France, Italy, Spain, or the Netherlands, you must ensure your One-Stop Shop (OSS) or Import One-Stop Shop (IOSS) filings are accurate for Q1.

Key Actions for March 2026:

1. Check Thresholds: If you are not using the OSS and are selling locally in EU member states, monitor your distance selling thresholds constantly.
2. Verify VAT IDs: European tax authorities are increasingly aggressive about verifying the validity of VAT numbers in real-time.
3. Talk to a Specialist: If you are unsure if your current setup is optimized for the latest EU directives, it may be time to consult a VAT accountant.

5. Maintain Your CRO Audit Exemption

In Ireland, the Companies Registration Office (CRO) is strict. To maintain your audit exemption, your Annual Returns (Form B1) must be filed on time. Late filing even once can put your exemption at risk; filing late twice in a five-year period results in a mandatory loss of audit exemption for two years.

This is an expensive mistake. An audit for a small company can cost thousands of Euros in unnecessary fees. This level of tax compliance is essential for any limited company, regardless of the industry.

6. Upcoming 2026 Deadlines: Mark Your Calendar

Compliance is a marathon, not a sprint. To stay ahead, you must look at the months following Q1:

• May 31, 2026: Deadline for various digital reporting requirements.
• October 31, 2026: The massive deadline for CGT Returns (asset disposals made in 2025) and Income Tax (Form 11) for those not using ROS extensions.
• November 15, 2026: The extended ROS deadline for filing and paying 2025 tax balances and 2026 Preliminary Tax.
• December 15, 2026: CGT payment deadline for disposals made between January and November 2026.
