What CAEN is and why it controls everything
CAEN (Clasificarea Activităților din Economia Națională) is the Romanian activity classifier, harmonised with the EU NACE Rev. 2 taxonomy. Every Romanian SRL declares one principal CAEN code plus any number of secondary codes, recorded at the Trade Register at incorporation and visible on the certificat constatator.
On its face, CAEN looks like an administrative formality. In practice, it determines:
- Whether the SRL can elect the microenterprise tax regime under Article 47 of Law 227/2015.
- Whether sectoral authorisations from ASF, ONJN, or BNR are required before operations begin.
- The default VAT regime at ANAF and the cod fiscal category.
- The Trade Register's view of which sectoral declarations need to accompany the formation dossier.
- Banking AML profiling at account-opening time — banks profile activity codes against their internal risk matrices.
Get the CAEN right at incorporation and the SRL flows through formation cleanly. Get it wrong and the recovery — changing the principal CAEN, refiling at the Trade Register, re-electing tax regimes — typically adds 2–4 months and €400–€1,200 in fees.
The CAEN Rev. 3 update (2024)
Romania transitioned to the new CAEN Rev. 3 classification in January 2024, replacing CAEN Rev. 2 which had been in force since 2008. The Rev. 3 update aligns Romanian classification with the EU's NACE Rev. 2.1 revision and introduces several new four-digit codes for digital economy activities.
Practically, this means:
- SRLs formed before 2024 retain their Rev. 2 codes by default, but ANAF and ONRC convert them to the closest Rev. 3 equivalent at the next administrative touch-point.
- SRLs formed in 2024 onwards declare CAEN Rev. 3 codes from the outset.
- The most common Rev. 2 → Rev. 3 mappings are clean (e.g. 6201: Computer programming is unchanged). A handful of activities have been re-classified or split — most notably parts of the consultancy and digital-services families.
The ONRC published an official mapping table between Rev. 2 and Rev. 3 codes; founders should check theirs annually until the transition stabilises.
Principal vs secondary codes
Romanian law treats the principal CAEN as the company's main economic activity for regulatory purposes. Secondary CAEN codes can be added freely (no statutory limit) and signal that the SRL may operate in those areas without changing its primary classification.
The distinction matters because:
- Microenterprise eligibility is assessed against the principal CAEN only. A technology company with 6202 (Computer consultancy) as its principal code and 7022 (Business and management consulting) as a secondary is eligible for the micro regime; a company with the same codes reversed is not.
- Sectoral authorisations are typically triggered by the principal code. An SRL with 6810 (Real estate buying and selling of own real estate) as principal must comply with real-estate sectoral rules; the same activity as a secondary is informational.
- Bank AML profiling weights the principal code more heavily than secondaries. A clean principal code (e.g. 6201) with adjacent secondaries paints a coherent picture; a sprawling secondary list with an unusual principal triggers questions.
The practical rule: declare the principal CAEN that matches the activity you actually intend as the company's main business, not the activity that produces the most-favourable tax outcome on paper.
The consultancy and management trap
The most-misapplied rule in Romanian tax: microenterprise exclusion for consultancy and management activities under Article 47 of the Fiscal Code.
A technology company that invoices some advisory work is not automatically excluded. A company incorporated with a principal CAEN of management consulting is.
The exclusion targets companies whose principal CAEN code falls in:
- 6920 — Accounting, bookkeeping, and tax-related activities.
- 7022 — Business and other management consultancy activities.
- 7320 — Market research and public opinion polling.
- 7022 / 7021 — Public relations and communication activities.
The rule does not exclude companies that derive incidental consulting revenue with a non-consultancy principal code. A SaaS company with principal 6202 (Computer consultancy — software-related, not management) that invoices some advisory work alongside subscription revenue is eligible for the microenterprise regime. The same company incorporated with principal 7022 would be excluded.
This is the most common reason for retroactive disqualification from the micro regime: founders incorporate with a generic management-consultancy code and only later realise the eligibility consequence. Recovery requires changing the principal CAEN — viable but slow.
Changing CAEN codes post-formation
Any CAEN code can be added, removed, or promoted from secondary to principal post-formation. The mechanics:
- Adding a secondary CAEN — simple Trade Register filing, €20–€40 state fee, 3–7 working days processing.
- Changing the principal CAEN — requires a Hotărâre AGA (shareholder resolution), an updated act constitutiv, and a Trade Register filing. State fees €40–€80, 5–10 working days.
- Effect on tax regime — a principal CAEN change to a microenterprise-eligible code becomes effective for the next fiscal year (1 January). Mid-year changes do not retroactively alter the current year's regime.
- Effect on VAT — a principal CAEN change rarely changes VAT obligations directly, but ANAF may reassess the cod fiscal category in adjacent quarters.
Founders weighing a CAEN change should plan it for the calendar year-end to align with the tax-regime reset.
CAEN-by-vertical: software, e-commerce, consulting, real estate
The right principal CAEN code depends on the actual business model — not the most fiscally convenient sounding code in the CAEN Rev. 3 taxonomy. The verticals where founders most often misfile, and the principal code we recommend in 2026:
Software development and SaaS
Principal CAEN: 6201 (Computer programming activities) — for software development, SaaS, mobile apps, custom development, and digital product engineering. Secondary CAEN 6311 (Data processing, hosting and related activities) for SaaS-style operations with significant infrastructure. CAEN 6201 is microenterprise-eligible; the consultancy trap (detailed below) does not apply because 6201 is software-related, not management-related. Avoid 6202 (Computer consultancy) as the principal — historically interpreted differently by ANAF inspectors and one of the most common reasons for retroactive microenterprise disqualification.
E-commerce and online retail
Principal CAEN: 4791 (Retail sale via mail order houses or via Internet) — covers all online product sales, dropshipping, and direct-to-consumer e-commerce. Microenterprise-eligible in 2026 but watch the legislative trajectory: draft proposals to exclude high-volume 4791 SRLs from microenterprise status have surfaced in recent OUG discussions. Secondary codes worth declaring: 5320 (Other postal and courier activities) if the business operates fulfilment, 6311 if there's a significant SaaS component, 7320 (Market research) if the company runs research operations adjacent to its retail.
Management consulting and advisory
Principal CAEN: 7022 (Business and other management consultancy activities) — and this is the case where microenterprise eligibility is statutorily denied. SRLs incorporated with 7022 as principal must operate at standard 16% CIT from the start. Founders with consulting-led business models often try to declare a different principal CAEN to keep micro eligibility — this strategy works only when the actual activity matches the declared CAEN. Misrepresentation to ANAF triggers retroactive disqualification, penalty interest, and potential fines under Law 227/2015 Articles 78–80.
Real estate and property holding
Principal CAEN: 6810 (Buying and selling of own real estate) for trading; 6820 (Renting and operating of own or leased real estate) for rental holding. Both codes carry sectoral compliance requirements under the Romanian Anti-Money-Laundering law (the AMLD6 transposition under Directive 2018/1673) — real-estate activities are enhanced-AML category. Microenterprise eligibility is preserved for these codes in 2026 but with thresholds tighter than for general activities. Bank onboarding for real-estate-CAEN SRLs is materially slower than for software or e-commerce — typically 15–30 working days at any of the six commercial banks (detail in our banking guide).
Healthcare-adjacent services
Principal CAEN: 8690 (Other human health activities) for non-licensed wellness, telehealth coordination, and health-services support; 8610–8623 for clinical activities requiring Ministry of Health authorisation. Founders entering this space often underestimate the regulatory overhead — both CAEN choice and authorisation timing materially affect the formation timeline.
Financial services and fintech
Principal CAEN 6499 (Other financial service activities n.e.c.), 6611–6622 (financial services support, securities), and adjacent codes trigger mandatory ASF authorisation before operations begin. Microenterprise status is statutorily excluded for all financial-services CAENs. Founders in this vertical typically operate outside the standard formation flow — Bespoke tier mechanics apply.
The CAEN choice is rarely a five-minute decision. We treat it as a substantive scoping question, not an administrative one.
The CAEN Rev. 3 transition: what changed
Romania transitioned from CAEN Rev. 2 to CAEN Rev. 3 in January 2024, aligning the Romanian classifier with the EU's NACE Rev. 2.1 revision. For SRLs formed under Rev. 2, the transition is partly automatic: ONRC maps existing principal codes to their nearest Rev. 3 equivalent at the next administrative touchpoint. Most mappings are clean — 6201 (Computer programming) is unchanged, 4791 (e-commerce retail) is unchanged, 6820 (Real estate rental) is unchanged. A handful of activity families saw substantive re-classification:
- Digital economy services — Rev. 3 introduced new four-digit codes for digital platform intermediation, app store operations, and digital content monetisation. SRLs whose Rev. 2 declarations covered these via generic 6311 or 6201 may need a refresh to capture the more precise Rev. 3 sub-codes.
- Consultancy and management — Rev. 3 split portions of the previous 7022 into more granular sub-codes covering strategy consulting, operations consulting, HR consulting, and IT consulting. The broad 7022 principal designation remains microenterprise-excluded; the new sub-codes inherit the exclusion. No founder has escaped the consultancy trap by reclassifying under Rev. 3.
- Health and wellness — Rev. 3 distinguishes more clearly between clinical health services (Rev. 3 8610–8623, requiring Ministry of Health authorisation) and non-clinical wellness coordination (8690 expanded sub-codes). For founders in telehealth or wellness-platform models, the Rev. 3 distinction matters operationally.
- Financial intermediation — Rev. 3 adopted EU NACE 2.1 alignment for fintech-adjacent activities, with new sub-codes covering payment services, e-money operations, and crypto-asset support. Most still trigger BNR or ASF authorisation requirements; the underlying microenterprise exclusions remain.
The practical implication for existing SRLs: review your principal CAEN against the Rev. 3 taxonomy at your next annual filing. Most SRLs need no action; a minority (typically those in digital-economy, consultancy, or fintech-adjacent verticals) benefit from a deliberate refresh that aligns the declared principal CAEN with the actual operating model. The cost of a refresh — typically €20–€80 in state fees plus accountant time — is dwarfed by the cost of misalignment if it triggers a retroactive microenterprise disqualification at audit.
For new SRL formations in 2026, declare directly under Rev. 3. The ONRC mapping table is published and stable; the underlying tax and licensing implications mirror Rev. 2 closely, with the few divergences noted above. We routinely cross-check the proposed principal CAEN against the founder's actual business model during discovery — this is the cheapest insurance available against a year-3 ANAF reassessment.
Sectoral authorisations triggered by certain codes
Some CAEN codes carry mandatory pre-operating authorisations that must be obtained before the SRL can invoice in that activity:
- Codes 6411–6499 (banking and financial intermediation) — BNR authorisation.
- Codes 6611–6622 (financial services support, securities) — ASF authorisation.
- Codes 9200 (gambling) — ONJN Class 1 or Class 2 licence.
- Codes 4730–4799 (specific retail) — sectoral retail licences from local authorities.
- Codes 8610–8690 (healthcare) — Ministry of Health authorisation.
Founders sometimes try to "open the door" to regulated activity by adding a sectoral CAEN as a secondary code without obtaining the licence, planning to add the licence later. This is risky — Romanian law treats unauthorised regulated activity as a serious compliance breach, regardless of whether actual operations have started. The practical rule: only add a regulated CAEN when you are ready to apply for the corresponding licence within the same quarter.
Frequently asked questions
Can I have multiple CAEN codes?
Yes. Romanian law sets no statutory cap on the number of secondary CAEN codes. The principal code is one. Most SRLs declare one principal and 3–10 secondaries covering adjacent activities. Adding more later costs €20–€40 per Trade Register filing.
What is the most common CAEN for a software/SaaS founder?
CAEN 6201 (Computer programming activities) is the cleanest principal code for software development. CAEN 6311 (Data processing, hosting and related activities) for SaaS-style operations with significant infrastructure. Avoid 6202 (Computer consultancy) as the principal if microenterprise eligibility matters — although 6202 software-related is technically distinct from 7022 management consultancy, ANAF interpretations have varied.
Can I add a CAEN code later after formation?
Yes, easily. Trade Register filing of €20–€40 with 3–7 working days processing. Adding secondaries does not require a shareholder resolution; promoting a code to principal does require a Hotărâre AGA and an updated act constitutiv.
Does a CAEN change cost money beyond the state fees?
Service fees from a Romanian formation provider for handling the change typically run €100–€300 depending on whether it is a simple secondary addition or a full principal change with shareholder resolution. State fees are €20–€80. Total realistic envelope: €120–€380.
Which CAEN codes are excluded from the microenterprise regime?
Banking, insurance, capital markets, gambling, and consultancy/management activities under Article 47 of the Fiscal Code. The headline excluded codes are 6411–6499 (banking), 6511–6520 (insurance), 6611–6622 (financial services support), 9200 (gambling), 6920 (accounting/tax services), 7022 (business management consulting), 7320 (market research).
Can I form the SRL with a generic CAEN and decide the real activity later?
You can form with a placeholder principal CAEN (e.g. 6201 or 6202), but it is rarely optimal. The principal CAEN drives microenterprise eligibility, sectoral licensing, and bank AML profiling — getting it right at incorporation prevents the 2–4 month recovery if it turns out to be wrong. We recommend treating the CAEN choice as a substantive decision, not a placeholder.
