A Trusted Partner for Your Business Finances

Choosing the right accountant isn’t just about compliance. It’s about finding a team you trust to understand your business, challenge you when it matters, and support you when things get complicated. That’s what Kinore is.

We take the time to get to know every client. Your goals, your pressures, your plans for growth. Whether you’re an established business looking for a fresh approach after changing accountants or a startup navigating your first annual return, we become the partner you can actually talk to. Not just at year-end, but whenever you need us. Our team of Chartered and Certified accountants brings depth and expertise across annual accounts, corporation tax returns, and the wider tax landscape, so you always have someone in your corner who genuinely understands your business.

What makes us different? Every engagement is built around a structured delivery model: one qualified accountant prepares your accounts, a senior team member reviews them, and a dedicated account manager owns the relationship and delivery timeline. This three-layer approach, backed by our ISO 9001 quality certification, is why 98% of our client accounts are filed early. Not just on time. Early.

What's Included

  • Preparation and filing of annual accounts and CT returns, including your Form CT1

  • Annual financial statements prepared in line with the Companies Act 2014

How We Ensure Your Tax Compliance

  • Dedicated Support

    Our systems and processes are designed for early delivery, not last-minute scrambles. We proactively reach out for your records and raise queries well in advance, with the aim of always delivering your accounts ahead of schedule. Every filing deadline is tracked from your annual return date to the date your corporation tax return is due, so nothing slips through the cracks. Whether it’s your first annual return or your twentieth, our team stays on top of every submission so you never have to chase.

  • Expert Oversight

    Getting your accounts filed is the baseline. What really matters is what we find along the way. Our qualified accountants review your company accounts with a focus on adding value: identifying tax efficiencies, flagging areas of concern before they become costly, and highlighting opportunities you might otherwise miss. We calculate how much you need to pay corporation tax and ensure you pay preliminary tax on time, but we also make recommendations that help your business keep more of what it earns.

  • Scalable Service

    Whether you’re an established business that needs a new provider or a startup that needs to be supported every step of the way, we’re built to meet you where you are. Our dedicated teams include payroll specialists, VAT experts, and management accountants who can support you with everything from intricate VAT compliance through to cashflow planning and strategic financial advice. As your limited company grows, our support grows with you.

Year End Accounts Deadlines

Corporation tax return (Form CT1). Filed with Revenue, with any tax paid, by the 23rd of the ninth month after your year end. A 31 December year-end means your CT1 and payment fall due on the following 23 September. Miss it, and Revenue adds a surcharge: 5% of the tax if you file within two months of the deadline, rising to 10% if you are more than two months late. Those surcharges are capped at €12,695 and €63,485 respectively.

CRO annual return (Form B1). Your financial statements are filed to the Companies Registration Office within 56 days of your Annual Return Date. Late filing costs you a €100 penalty on the day after the deadline, then €3 per day, up to a maximum of €1,200 per return.

Since 16 July 2025, a single late return no longer costs you audit exemption on its own. Instead, a small or micro company loses audit exemption only if it files late a second time within a rolling five-year period, and it then has to have audited accounts for two years, an audit it would otherwise never need. Companies within a group can still lose the exemption on a single late filing.

We ensure your company stays compliant with Irish tax laws and CRO requirements so you can focus on what you do best.

What We Need to Get Started

  • Understanding Your Business

    Whether you’re an established company looking for a better return service after years with another firm, or a startup that needs guidance from day one, we begin with a discovery call to understand where you are and where you want to go. Already have an accountant? We handle the transition for you, requesting your full records from your current provider and making the switch seamless and worry-free. You won’t need to manage the handover; that’s our job.

  • Company Details & Financial Records

    We’ll request your company details and full financial records directly from your outgoing accountant: last year’s accounts, your most recent tax returns, bookkeeping reports, and your profit and loss account. If you’re a limited company in Ireland filing for the first time, we’ll walk you through exactly what’s needed. Our team proactively gathers everything required so there’s no delay in preparing accurate filings and calculating your corporation tax due.

Annual Accounts and Corporation Tax FAQs

What does the Annual Accounts & CT Returns service include?

We prepare and file your statutory financial statements, your CRO annual return (Form B1), and your corporation tax return (Form CT1). Depending on your needs, we can also manage VAT returns, preliminary tax payments, and additional filings via the Revenue Online Service. Every return is submitted on time and your company remains fully compliant with Irish tax laws.

Do all businesses need to file year end accounts?

Every Irish limited company does, every year, even if it didn’t trade, a dormant company still files a CT1 and a CRO annual return. Sole traders and partnerships prepare accounts to support a Form 11 income tax return rather than filing with the CRO.

What's the difference between year end accounts and the CRO annual return?

Your year-end accounts are the financial statements, profit and loss, balance sheet, and notes. The CRO annual return (Form B1) is the separate filing that submits those statements to the Companies Registration Office and keeps your company in good standing. You need both, and we handle them in a single engagement.

What is the difference between a CRO annual return and a corporation tax return?

They go to different bodies. The annual return (Form B1) is filed with the Companies Registration Office and confirms the company’s details and financial statements. The corporation tax return (Form CT1) is filed with Revenue through ROS and calculates the tax due on profits. Every Irish company must file both, on separate deadlines.

What is the difference between annual accounts and a tax return?

Annual accounts are the financial statements, the profit and loss account and balance sheet, that show how the company performed. The corporation tax return uses those figures to calculate what tax is owed to Revenue. The accounts describe the position; the tax return applies the tax rules to it. We prepare both as one connected process.

Where do I file my company's tax return and accounts in Ireland?

Corporation tax returns are filed with Revenue online through ROS, while the annual return and financial statements go to the Companies Registration Office through the CORE portal.

The two systems and deadlines are separate. We handle both submissions for you, so nothing is missed or duplicated between Revenue and the CRO.
