Partnership Tax Return Form 1 (Firms) for Revenue Submission

Understanding the Partnership Tax Return (Form 1(Firms)) for 2025 in Ireland

The Form 1(Firms) is an official document issued by the Office of the Revenue Commissioners in Ireland, specifically designed for partnerships to report their income and capital gains for the tax year ending 31 December 2025. This form is a vital part of the Irish tax compliance process for partnerships, ensuring that the Revenue accurately assesses the partnership’s taxable income and capital assets for the year.

Purpose and Scope of the Form

The primary purpose of the Form 1(Firms) is to provide a comprehensive declaration of the partnership’s income, gains, and chargeable assets acquired during the 2025 tax year. It also records details about the partnership’s structure, partners, and any changes in the partnership arrangement. This form is used by the partnership’s precedent partner—the partner named first in the partnership agreement or the one with precedence in the absence of an agreement—to submit the collective financial information to Revenue.

In addition to reporting the partnership’s income and gains, the form captures information about individual partners, including their residency status, share of income, and any salary or interest received. Each partner must also submit a separate personal tax return, typically using Form 11.

Who Needs to Complete the Form?

• The precedent partner or the partner named with precedence in the partnership agreement is responsible for completing and submitting the form.
• If no partner resides in Ireland, the responsibility falls on the partnership’s agent, manager, or factor who is resident in Ireland.
• Partnerships that have acquired chargeable assets or generated income during 2025 must file this return to comply with Irish tax laws.

How to Fill Out the Form

Completing the Form 1(Firms) requires careful attention to detail. Here are some key points:

• Partnership Details: Provide the legal name of the partnership, its tax reference number, and the primary trade or profession. If there are any changes in the partnership’s structure or trading address, these must be updated.
• Partner Information: List all partners, indicating whether they are resident or non-resident in Ireland. For each partner, include their PPSN or foreign tax number, share of income (Case I/II or other), and details about salary or interest received.
• Partnership Income and Gains: Declare the total income, capital gains, and assets acquired during 2025. Attach additional schedules if necessary, especially if there is insufficient space.
• Changes and Events: Record any changes in the distribution of profits or partner status throughout the year, specifying dates and nature of these changes.

Supporting Documents and Attachments

While the form itself is comprehensive, supporting documentation may be required, such as schedules detailing partner shares, asset acquisitions, or specific income items. Any additional pages should be clearly marked and attached securely to the main form.

Where and How to Submit the Form

The completed Form 1(Firms) should be sent to the following address:

Office of the Revenue Commissioners Collector-General’s Division PO Box 354 Limerick

Alternatively, partnerships are encouraged to file electronically via the Revenue Online Service (ROS). Access to ROS can be obtained through the official website at www.revenue.ie. Filing electronically is often faster and reduces the risk of errors.

Important Deadlines and Penalties

The predecessor partner must file the return on or before 31 October 2026. Failure to meet this deadline may result in penalties or interest charges. It is also mandatory for each partner to submit their personal tax return (Form 11), indicating any expressions of doubt regarding specific tax treatments.

Common Errors to Avoid

• Entering incorrect partner PPSNs or foreign tax numbers.
• Omitting changes in partnership structure or profit distribution.
• Failing to attach necessary schedules or supporting documents.
• Missing the filing deadline, which could lead to penalties.

By carefully completing and submitting the Form 1(Firms) for 2025, partnerships ensure compliance with Irish tax legislation and avoid potential penalties. For further guidance, partnerships should consult the official instructions provided by Revenue or seek advice from a qualified tax professional.
