Ireland is a common European base for international groups, and its compliance is predictable but unforgiving about dates. Two authorities matter. The Companies Registration Office (CRO) receives the annual return and the financial statements. The Revenue Commissioners receive the corporation tax return and handle VAT and payroll. The annual return and the tax return are separate filings with separate deadlines, and filing one does not satisfy the other.

This guide covers the private company limited by shares (Ltd), the usual vehicle for a foreign-owned subsidiary, and notes where the designated activity company (DAC) and a branch differ. It is written for founders and for legal, finance and operations teams.

Updated November 9, 2026. Irish deadlines are keyed to the company's annual return date, so use the dates below as the usual pattern and confirm them with the CRO and Revenue.

Entity compliance Ireland: the quick answer

• File the annual return (Form B1) with the CRO each year, even when the company is dormant. The first annual return is due six months after incorporation, according to professional sources.

• File the corporation tax return (Form CT1) within nine months of the accounting period end, and no later than the 23rd day of the ninth month.

• Pay preliminary corporation tax before filing, file VAT returns, and remit PAYE and PRSI monthly.

• Keep the register of beneficial owners and the CRO records current.

What determines an Irish company's compliance requirements?

The company type and size decide the content. A private Ltd company is the most common form, and professional sources note that it does not need to hold an annual general meeting if certain conditions are met. Small companies can file abridged financial statements and may qualify for an audit exemption, while larger companies file full accounts and need an audit. Late filing can cause a company to lose its audit exemption.

Tax profile also matters. The standard corporation tax rate on trading income is 12.5 percent, and professional sources describe higher rates for passive income. Large groups in scope of the global minimum tax rules face a higher effective rate, so confirm the regime that applies to your group.

Annual entity requirements in Ireland: the core checklist

1. Annual return to the CRO

Every Irish company files Form B1 through the CRO's online system. The form records directors, the company secretary, the registered office and the shares as at the annual return date (ARD). Professional sources disagree on the filing period, with some describing 28 days after the ARD and others 56 days, and the period can be longer when financial statements accompany the return, so confirm the date with the CRO for your ARD. Late filing leads to fines and a loss of audit exemption, according to professional sources, and persistent failure can lead to strike-off. The online filing fee is modest.

2. Financial statements

The directors prepare financial statements under Irish or international standards, and an abridged version is filed with the annual return for qualifying small companies. Filed statements are public. Keep the signed statements, the directors' report and any auditor's report together. Dormant companies must still file.

3. Annual general meeting

A Ltd company can dispense with the annual general meeting if it has a sole member or the members agree in writing, while other companies must hold one within fifteen months of the previous one, according to professional sources. Record the decision either way.

4. Corporation tax return

Form CT1 is filed electronically through Revenue's online service. Professional sources place the deadline nine months after the end of the accounting period, no later than the 23rd day of the ninth month, and describe payment due about nine months and 21 days after year-end. Companies also pay preliminary tax before the filing date. The return should align with the CRO annual return details. Even a dormant or non-trading company must file.

5. Beneficial owners

Irish companies maintain an internal register of beneficial owners and file the information with the central register of beneficial ownership. Changes must be reported, so update the filing after any change of shareholders or control. Check the current deadline with the register.

Tax and indirect tax obligations

The standard VAT rate is 23 percent, with reduced rates for some goods and services. VAT returns are generally filed every two months, due by the 23rd of the month after the period when filed online, and an annual return of trading details can be required. Employers file payroll reports in real time and remit PAYE, USC and PRSI monthly.

Dividends, interest and royalties paid abroad can attract withholding tax, with exemptions under EU rules and treaties when conditions are met, so collect declarations. Related-party transactions need arm's-length pricing, and larger groups prepare transfer pricing documentation.

Foreign-owned subsidiaries

Ireland has no restriction on foreign ownership of a Ltd company. The company must have at least one director who is an EEA resident, or the company must put in place a bond or obtain a certificate of exemption, according to Irish company law, so confirm which option fits your structure. A company secretary and a registered office in Ireland are required. Foreign corporate shareholders provide apostilled documents.

Banks apply due diligence to foreign-owned accounts. Intercompany loans, services and royalties need contracts and pricing support, and transfer pricing and interest limitation rules can restrict deductions. Check the substance of the Irish company if it is part of a group tax structure.

First-year and event-triggered obligations

In the first year, the company is incorporated through the CRO, registers with Revenue for corporation tax, VAT and payroll, opens a bank account, records its beneficial owners and adopts a constitution. The first annual return is due six months after incorporation, and the first accounting period can be up to eighteen months.

Events that trigger filings include a change of directors or secretary, a change of registered office, a share allotment or transfer, a change of name, a merger and a strike-off or liquidation. Changes of the registered office are filed on the relevant CRO form, and the details should match the tax records.

Employment and local requirements

Irish employers give written terms of employment, register as employers with Revenue, run payroll with real-time reporting, and pay employer PRSI. Employees have statutory minimum wage, annual leave, notice and unfair dismissal rights, and auto-enrolment into a pension scheme is being phased in. Many foreign-owned subsidiaries use a local payroll provider.

Record-keeping and governance in Ireland

Irish companies must keep adequate accounting records that explain their transactions, and the law sets a retention period of six years from the end of the relevant financial year, according to professional sources, so confirm the period with your accountant. The directors approve the financial statements and sign a statement on compliance where required, so keep board minutes with the filed version. Keep the statutory registers, such as members, directors, secretaries and beneficial owners, at the registered office or another notified location. A foreign parent should also keep a record of who holds the online filing credentials for the CRO and Revenue, and review it each year.

Build a compliance calendar for Ireland

A compliance calendar turns the rules above into dated tasks with named owners. Start from the financial year-end and the incorporation anniversary, then add the recurring monthly and quarterly items. Review it each quarter, because deadlines, extensions and registry systems change.

• Six months after incorporation: file the first annual return.

• Each year within the CRO period after the ARD: file Form B1 with financial statements.

• Before the CT1 date: pay preliminary corporation tax.

• Nine months after year-end, by the 23rd: file Form CT1.

• Every two months: VAT returns by the 23rd.

• Monthly: PAYE and PRSI, and after any change, beneficial owner and CRO updates.

Common mistakes

• Confusing the CRO annual return with the CT1 tax return.

• Letting the annual return slip because the company is dormant.

• Losing the audit exemption through late filing.

• Forgetting the preliminary tax payment.

• Failing to update the beneficial owner filing after a change.

• Having no EEA-resident director and no bond or exemption.
