Who should avoid:
Avoid the exclusive use of code 4212 if the main activity of your company shifts towards other commercial or related branches not specified in the official description. See the excluded activities section below.
Authorization procedure and Trade Register aspects for CAEN 4212
For registering the activity 'Construction works of surface and underground railways' (CAEN code 4212) with the Trade Register (ONRC), the company must submit the registration file in accordance with Law no. 265/2022 and ONRC regulations. Mandatorily, a sworn statement under Law 359/2004 regarding the fulfillment of legal conditions for the operation of the enterprise is included. In the case of the registered office, supporting documents are required, and for railway activity, the opinion of the Romanian Railway Authority (AFER) is mandatory – including a safety certificate and a transport license (if traction is also performed). At registration, the main activity object is completed according to CAEN rev. 3; it is recommended to additionally mention codes for related works (e.g., 4211 for bridges or 4299 for other engineering constructions).
Regulatory framework, specific approvals and control institutions
The activity of railway construction is strictly regulated by Law 55/2006 on railway safety (republished) and GEO 73/2019 (the railway code). Before commencing works, a building permit must be obtained from the relevant ministry (MTIC) or from county councils, depending on the scale. The technical opinion of AFER is mandatory for infrastructure design; for execution, a certification attestation issued by the Romanian Association for Railway Construction (ARCF) or AFER is required. Control institutions include: State Inspectorate for Boilers and Installations (ISCIR) – checks signaling systems; Territorial Labor Inspectorate (ITM) – for occupational safety; Environmental Guard – for impact on land and construction waste. Recommendation: hiring a technical responsible for execution (RTE) certified in the railway field.
Tax management, audit risk by Tax Authority (ANAF) and specific accounting
From a fiscal perspective, CAEN code 4212 falls under construction (Section F), and the VAT regime is the general one (19% rate or 5% for housing, which is not applicable here). Corporate income tax of 16% or micro-enterprise income tax (1% turnover under EUR 500,000) applies. The single declaration is filed annually for income from independent activities (PFA). The fiscal vector is completed at the Tax Authority (ANAF) specifying the CAEN code and VAT regime. Payments are made through the RO e-Factura system (mandatory from 2024) and RO e-Transport system (if machinery and materials are transported). The risk of ANAF audit is medium to high due to large volumes of materials (ballast, sleepers, rails) and labor. Accounting must distinctly record fixed assets (track equipment), provisions for warranties (1-2 years), and work in progress. It is recommended to periodically verify the tax base for the special building tax (if depots are owned). Justifying documents: contractor contracts at lump-sum or on-cost basis, reception minutes upon completion of works, quality certificates for materials (according to SR EN 13674-1 for rails). Any deviation regarding ONRC registration or failure to obtain AFER approvals leads to suspension of activity and fines between 5,000 and 50,000 lei.
