CONSTRUCTION Companies in Ireland
Approximately 70,404 real businesses classified under Construction in Ireland, with officer, shareholder and beneficial ownership records sourced directly from official government registries.
Approximately 70,404 real businesses operate in the Construction sector across Ireland. Ask who is building a project and you will usually get three answers: the prime contractor, the subcontractor, and the special-purpose vehicle set up just for that job. Construction — covering general contractors, specialised trade subcontractors, and infrastructure developers delivering roads, bridges, and utilities — is built around project-based, often temporary corporate structures, which makes ownership chains genuinely harder to resolve than in a single-entity business. That fragmentation is also why construction ownership sits under sustained anti-money-laundering and public-procurement scrutiny in most jurisdictions.
47 companies in this sector are indexed on Zavia so far, part of a continually growing dataset.
Beneficial-ownership and registration rules for Construction companies in Ireland follow the same national framework as every other sector there.

Analysis
What this data actually tells you
Construction in Ireland runs on a withholding-tax system, Relevant Contracts Tax (RCT), that acts as a live, ongoing compliance signal rather than a one-time registration check. Principal contractors must deduct RCT from payments to subcontractors in construction, forestry and meat-processing at one of three rates — 0%, 20% or 35% — with the applicable rate reflecting the subcontractor’s own tax-compliance standing with Revenue. Subcontractors must supply their name as registered with Revenue and their Tax Reference Number before a contract can be properly registered.
RCT compliance, filing and payment now runs entirely through Revenue Online Service (ROS), with Revenue applying increased scrutiny through 2025-2026. The obligation extends to non-resident subcontractors doing work in Ireland, with the principal contractor still required to withhold RCT from the gross payment regardless of the subcontractor’s home jurisdiction. For verification, a subcontractor’s current RCT rate is a real, checkable, and dynamic signal of its Revenue standing — not something a company filing shows on its own.

Who uses Ireland construction ownership data
The three checks this sector's data is most often run for.
RCT (Relevant Contracts Tax) registration check
Principal contractors must deduct Relevant Contracts Tax from payments to subcontractors in construction, forestry and meat-processing at rates of 0%, 20% or 35% — the rate applied depends on the subcontractor’s own Revenue compliance record, making it a real, checkable signal of a subcontractor’s tax standing.
Fully digital RCT compliance tracking
All RCT compliance, filing and payments run online through Revenue Online Service (ROS), with increased Revenue scrutiny in 2025-2026 — a subcontractor’s RCT rate (0/20/35%) is a live, checkable Revenue record, not a static classification.
Non-resident subcontractor exposure
RCT applies even to non-resident subcontractors carrying out work in Ireland, with the principal contractor required to deduct it from the gross payment — a real, checkable withholding obligation that follows the work location, not the subcontractor’s home jurisdiction.
