Company Formation Services for Ireland and the UK

Choosing the right structure: Ireland vs UK

A private company limited by shares is the default vehicle for most trading businesses in both Ireland and the UK. Irish companies register with the Companies Registration Office under the Companies Act 2014; UK companies register with Companies House under the Companies Act 2006. Both offer limited liability, separate legal personality, and flexibility on share classes — but tax treatment, filing deadlines, and director compliance differ.

Irish companies face corporation tax on worldwide income, with potential knowledge-development box and R&D credits for qualifying activities. UK companies follow UK corporation tax rules with associated company considerations if you control multiple entities. Sole traders avoid incorporation costs but lack limited liability and may pay higher effective tax at certain profit levels. FinnAccountings models sole trader versus limited company outcomes at your projected profit so the structure choice is numerical, not guesswork.

Cross-border groups — an Irish parent with a UK subsidiary or the reverse — require careful alignment on transfer pricing, dividend flows, and permanent establishment. We coordinate formation timelines so both entities exist before inter-company trading begins, avoiding invoices between non-existent legal persons.

CRO incorporation in Ireland

Irish incorporation requires a company name acceptable to the CRO, a registered office address in Ireland, at least one director (with residency rules for certain company types), a company secretary, and an constitution — formerly memorandum and articles. FinnAccountings prepares Form A1 and supporting documents, checks name availability, and submits electronically through CRO CORE.

Upon registration, you receive a certificate of incorporation and company number. Within weeks you must register for corporation tax with Revenue, and typically for VAT and PAYE if employees or taxable turnover apply. Missing the corporation tax registration window can delay tax refunds and create compliance gaps from the first accounting period.

First annual return (Form B1) is due six months after incorporation, with the first financial statements attached if the ARD falls within the initial period. We calendar these deadlines at formation so your first CRO filing is not a surprise.

Companies House incorporation in the UK

UK incorporation via Companies House requires a unique company name, registered office in England, Wales, Scotland, or Northern Ireland, at least one director, and a statement of capital. Most formations use Model Articles. FinnAccountings files electronically with same-day or standard service depending on urgency.

After incorporation, register for corporation tax with HMRC within three months of starting to trade — defined broadly as any business activity including bank interest. VAT registration follows UK thresholds; employer registration is required before the first pay date. MTD for VAT applies from registration if you are not exempt.

Confirmation Statement (CS01) replaces the annual return, due at least annually with a snapshot of officers, registered office, and PSC — Persons with Significant Control — information. PSC registers must be accurate; inaccuracies are a common Companies House penalty trigger.

Tax and payroll registrations from day one

An incorporated company without Revenue or HMRC registrations cannot operate payroll legally or recover VAT on setup costs through the normal channels. FinnAccountings sequences registrations: corporation tax first, then VAT if projected turnover or voluntary recovery warrants it, then PAYE/PRSI or PAYE/NI when the first employee or director salary is planned.

Irish companies need a ROS digital certificate for most Revenue interactions. UK companies require HMRC Government Gateway credentials and, for payroll, RTI activation. We guide you through credential setup and store authorised agent links where you appoint FinnAccountings to file on your behalf.

VAT registration on incorporation is often wise when you lease premises, buy equipment, or incur professional fees with VAT — voluntary registration lets you reclaim input tax from the first VAT return rather than absorbing it as a cost.

Converting from sole trader to limited company

Many growing sole traders incorporate to limit liability and manage tax efficiently. Conversion involves transferring assets and contracts to the new company, often at market value, with potential capital gains and stamp duty implications in Ireland and SDLT or LBTT considerations in the UK on property transfers.

FinnAccountings coordinates cessation accounts for the sole trade — final Form 11 or SA100 — with opening balances for the new company. Goodwill, debtors, and equipment transfers are documented with fair value evidence for Revenue and HMRC.

Bank accounts must be retitled or replaced; invoices reissued in the company name; contracts novated where required. Our checklist covers practical steps beyond the CRO or Companies House certificate so trading continuity is not interrupted.

Post-formation compliance calendar

Formation is an event; compliance is ongoing. Irish companies file Form B1 annually, hold AGMs where required, and submit corporation tax returns (Form CT1) nine months after year-end. UK companies file confirmation statements, annual accounts at Companies House, and CT600 with HMRC.

FinnAccountings loads your compliance calendar at incorporation: CRO ARD, Companies House CS01, corporation tax payment and filing dates, VAT periods, and payroll submission obligations. Automated reminders fire ahead of each deadline.

Integrated bookkeeping from day one means your first year-end accounts are a structured export from reconciled transactions — not a frantic reconstruction. Investors, lenders, and grant bodies increasingly expect clean first-year books; starting with FinnAccountings avoids expensive catch-up fees later.
