For many businesses, company compliance and reporting is the backbone of sustainable growth and long-term stability. Business owners need to choose the right legal structure, meet CRO filing requirements, stay on top of Revenue obligations like VAT, payroll, and corporation tax (see our Revenue Compliance Calendar for the full filing schedule), and apply the correct financial reporting standard. Together, these form the foundation of a company’s long-term legal and financial health, and at RizFin, we make this side of things clear, structured, and manageable.
Company Size Thresholds
Understanding your size classification is the first step in managing compliance effectively. Ireland’s company size thresholds follow EU regulations (SI 301/2024). Check the linked statute for the current figures, since thresholds are periodically revised.
| Size | Turnover | Balance Sheet Total | Employees |
|---|---|---|---|
| Micro | ≤ €900,000 | ≤ €450,000 | ≤ 10 |
| Small | ≤ €15 million | ≤ €7.5 million | ≤ 50 |
| Medium | ≤ €50 million | ≤ €25 million | ≤ 250 |
| Large | Above Medium | Above Medium | > 250 |
You qualify for a size category based on meeting two out of three criteria over two consecutive years. For additional guidance, CRO.ie and Revenue.ie are the authoritative sources.
Accounting, Filing, and Audit Requirements by Size
Once you know your company size, here’s how it affects your obligations:
| Size | Audit Requirement | Filing Needs | Typical Accounting Standard |
|---|---|---|---|
| Micro | Usually exempt if conditions met | Abridged financial statements with CRO (B1), plus tax filings (CT1, Form 11 if director self-assessed) | FRS 105 (Micro-entities Regime) |
| Small | Audit exemption usually available if thresholds met and no ineligible company status | Full financial statements (abridged filing option), CRO B1, CT1, VAT, PAYE as applicable | FRS 102 Section 1A |
| Medium | Audit generally required | Full statutory accounts, CRO B1, CT1, VAT/PAYE, other returns as relevant | FRS 102 (full) or FRS 101 (reduced disclosure) |
| Large | Mandatory audit | Full consolidated accounts if part of a group, CRO B1, CT1, VAT/PAYE, other statutory returns | FRS 102, FRS 101, or IFRS (listed companies must use IFRS) |
Key clarifications:
- Audit exemption: only micro and small companies can claim it, subject to eligibility. Medium and large companies must be audited.
- Filing: all companies must file an annual return (B1) with financial statements to the CRO, but the level of disclosure depends on size.
Micro and small companies may benefit from audit exemptions and reduced disclosure requirements, keeping compliance costs lower. Once you reach medium or large size, a full audit and broader reporting obligations apply.
Financial Reporting Standards in Ireland
| Standard | Best For | Highlights |
|---|---|---|
| FRS 105 | Micro entities | Simplified regime, no director’s report, very limited disclosures |
| FRS 102 Section 1A | Small companies | Reduced disclosure, accrual-based, easier presentation |
| FRS 102 (full) | Medium companies | Full standard framework, aligns with international principles |
| FRS 101 | Group entities using IFRS in consolidated accounts | Reduced disclosure for subsidiaries/parents in IFRS groups |
| IFRS | Large/public firms, especially listed PLCs | Full international reporting standard, required on regulated markets |
FRS 102 triennial review: a major update to FRS 102 is now in effect for accounting periods beginning on or after 1 January 2026, including lease recognition (bringing most leases onto the balance sheet, similar to IFRS 16) and revenue recognition changes aligned more closely with IFRS 15 principles. If your accounting periods fall under this, it’s worth discussing with us to understand the impact on your statements.
What RizFin Does, and Doesn’t, Handle Directly
What we do: clean bookkeeping aligned with Revenue compliance, payroll setup and submissions, VAT/CT1/Form 11 support and coordination, financial statements under FRS 105 or FRS 102, and structured systems, SOPs, and clear month-end reporting.
What we don’t do directly, and how we handle it instead:
| Not Offered Directly | Why | Our Approach |
|---|---|---|
| Statutory audits | Requires a regulated audit firm | We prepare audit-ready records |
| Tax planning or structuring | Needs specialist expertise | We work alongside your tax advisor |
| Investment or pension advice | Requires financial regulation | We refer to trusted partners |
| Legal company formation | Legal, not finance, service | We refer to trusted specialists |
| One-off payroll or tax fixes | Not strategic or scalable | We build reliable, ongoing systems instead |
Choosing the Right Setup for Your Business
Based on your company’s size and stage, we build a structured system around whichever of our core stages applies to you: setting up, staying on top of your records, getting your year-end right, or closing down, scaled to what a micro entity, a small company, or a larger, more complex structure actually needs. Get in touch to discuss your current obligations and future goals, and we’ll build a system that keeps your business compliant and confident.
Final Thoughts
Company compliance and reporting isn’t just about ticking boxes. It’s about clarity, structure, and confidence in your financial operations. At RizFin, we simplify this by building reliable systems that keep you compliant with CRO and Revenue, while giving you clear financial insight to grow your business.
