Ce este CUI-ul unei firme?

CUI (Codul Unic de Inregistrare) este un cod numeric unic atribuit fiecarei firme la inregistrarea la Registrul Comertului. Este emis de ANAF si serveste ca identificator fiscal al firmei in Romania. Poate avea intre 2 si 10 cifre.

Care este diferenta intre CUI si CIF?

CUI este codul fiscal numeric (ex: 12345678), iar CIF este CUI-ul cu prefixul RO (ex: RO12345678). CIF-ul se foloseste doar pentru firmele inregistrate ca platitoare de TVA. Daca firma nu este platitoare de TVA, CIF-ul este identic cu CUI-ul.

Cum verific daca o firma este platitoare de TVA?

Poti verifica daca o firma este platitoare de TVA introducand CUI-ul in validatorul de pe curs.online. Alternativ, poti verifica pe site-ul ANAF (anaf.ro) sau in sistemul VIES al Comisiei Europene pentru tranzactii intracomunitare.

Ce inseamna Split TVA?

Split TVA (plata defalcata a TVA) este un mecanism prin care TVA-ul se plateste separat de baza impozabila, direct intr-un cont special de TVA. Anumite firme sunt obligate sa aplice Split TVA conform legislatiei romanesti.

Unde gasesc CUI-ul unei firme?

CUI-ul unei firme se gaseste pe: facturi (obligatoriu), certificatul de inregistrare, site-ul ANAF (anaf.ro), Registrul Comertului (onrc.ro), sau pe site-ul/pagina de contact a firmei.

Unique Registration Code (CUI)

What is CUI?

CUI (Unique Registration Code) is a unique numeric code assigned to each company upon registration with the Trade Register. It is issued by the Ministry of Public Finance through ANAF and serves as the company's tax identifier in Romania.

The CUI can have between 2 and 10 digits and is used in all tax documents: invoices, tax returns, commercial contracts. The prefix "RO" is added only when the company is a VAT payer (e.g., RO12345678).

Through the CUI you can find public information about a company: name, registered office address, whether it is a VAT payer, whether it applies Split VAT, or if it is in insolvency proceedings.

Difference between CUI, CIF, and Registration Number

CUI (Unique Registration Code)

The company's tax code, consisting of digits (e.g., 12345678). It is assigned by ANAF and used for tax identification. All companies in Romania have a CUI.

CIF (Fiscal Identification Code)

CIF = CUI with the prefix "RO" (e.g., RO12345678). It is used only for companies registered as VAT payers. If a company is not a VAT payer, its CIF is identical to its CUI.

Registration Number (Order number in the Trade Register)

Format: J40/1234/2020 (county/number/year). It is assigned by the Trade Register Office and identifies the company legally. Do not confuse it with the CUI, which is fiscal.

Where to find a company's CUI?

1. On invoices — the CUI appears mandatory on any invoice issued by the company.

2. Registration certificate — the document issued by the Trade Register upon company establishment.

3. ANAF website — on anaf.ro you can search for information about any company using the CUI.

4. Trade Register (ONRC) — on onrc.ro you can search for companies by name or CUI.

5. On the company's website — many companies display the CUI in the footer or on the contact page.
