Setting Up as a Contractor in Ireland: Your Own Limited Company Step by Step

For IT professionals, engineers, consultants, and other independent specialists, the contractor limited company is the standard vehicle for contracting in Ireland: agencies and end clients expect it, it separates your business from your person, and it puts you in control of how you are paid. This guide walks through the setup in the order that works — and the running obligations that begin the day the company exists.

Why contractors use a limited company

Three reasons dominate. Market access: many agencies and clients will only engage an incorporated contractor, full stop. Limited liability: contract work carries professional risk, and the company structure keeps that risk, alongside professional indemnity insurance, away from your personal assets. Payment structure: a company lets you pay yourself deliberately — salary, pension contributions, expenses — rather than receiving whatever remains after someone else's deductions. If you are still weighing the alternatives, our comparison of sole trader vs limited company covers the fundamentals; for most professional contractors, the market has effectively made the decision already.

Forming the contractor company

The formation itself follows the standard route in our step-by-step registration guide, with a few contractor-specific notes:

1. 1Name and image. Contractors trade on a professional reputation; run the free name check early and pick something that looks right on a statement of work.
2. 2You as director — plus a secretary. A company with one director cannot have that person as secretary too, so most solo contractors appoint a company secretary service and keep the structure clean.
3. 3Registered office. Client-facing contractors often prefer a professional registered office address over a home address on the public register.
4. 4Shares kept simple. One director, one shareholder, a simple share structure — complexity here buys a solo contractor nothing.

Allow realistic lead time for the identity requirements and bank account, as covered in how long formation takes — agencies will want your company number, bank details, and insurance certificates before the first timesheet.

Registrations and the first contract

Before invoicing, the company needs its tax footprint: corporation tax registration on commencing to trade, VAT registration — most contractors exceed the services threshold quickly, and many register from day one because agencies expect VAT invoices — and employer registration, because the company's first employee is you. Our VAT and tax registration service handles the set. From there, each contract runs through a simple loop: signed agreement, timesheets, a numbered VAT invoice from the company, payment into the company account.

Paying yourself as a contractor

This is where contractors most often go wrong in year one. The day rate lands in the company's account; it becomes yours through the same three channels as any owner-director — salary through payroll, reimbursed business expenses at approved rates, and, where profits allow, dividends — as set out in our guide to paying yourself from a limited company. Two contractor-specific points deserve emphasis:

• Pension contributions are the contractor's quiet superpower. Employer contributions from the company are among the most efficient uses of contracting income; build them into the plan early rather than as a year-end afterthought.
• Watch the close-company rules. Professional income retained in the company can attract a surcharge if simply left undistributed, so the salary-retention balance is a calculation, not a guess.

The running obligations

A contractor company is a real company, with the full statutory calendar: RBO at five months, the first B1 at six, continuous books of account, VAT periods, real-time payroll, and corporation tax around year end — all mapped in our first-year compliance calendar. For a one-person company the volume is modest but relentless, which is why most contractors put the whole cycle on a monthly bookkeeping package and spend their attention on billable days instead.

If you have a contract offer in hand and need the company, registrations, and payroll ready for a start date, request a call — we set up contractor companies as a single coordinated package, formation through first payslip.
