How to verify RNC in Dominican Republic?
RNC check on Impuestos Internos website
The RNC (Registro Nacional de Contribuyentes) is the Dominican Republic's taxpayer identification number, issued by the DGII (Dirección General de Impuestos Internos — Internal Revenue). The DGII portal provides free, instant RNC verification by number, cédula, or company name.
- Access the Tool: Go to the DGII RNC Consultation Portal.
- Enter Search Terms: Search by RNC number (9 digits for legal entities, e.g.
401-50625-4, the DGII's own RNC), 11-digit cédula (for natural persons), or company name. All three search modes are supported. - Review the Result: A successful lookup returns:
- ID/RNC
- Company name
- Tradename
- Category
- Payment regime (NORMAL for the ordinary regime — see FAQ below)
- State (Active, Suspendido, Dado de Baja)
- Economic activity
- Local Management
- Electronic Billing authorization
- VHM Marketing Licenses
The Estado (State) field is critical for compliance. A Suspendido status usually means outstanding tax returns; Dado de Baja means the RNC has been deregistered, although a Dado de Baja Administrativa status can be reactivated. See the FAQ below for buyer consequences.
For ITBIS rates, e-CF deadlines, filing and withholding rules, see the Dominican Republic ITBIS guide.
Frequently Asked Questions
When does a natural person use their cédula as their tax ID vs. needing a separate 9-digit RNC?
For Dominican citizens and resident individuals, the 11-digit cédula de identidad y electoral is itself the tax ID: the DGII uses the cédula number as the RNC for natural persons, so no separate number is issued. A 9-digit RNC is assigned by the DGII to legal persons and to foreigners without a Dominican cédula. The DGII issues two kinds of RNC: Contribuyentes, with recurring filing obligations, and Registrados, for people who only carry out occasional procedures. When you look up an individual on the DGII portal and see their 11-digit cédula returned, that is the correct tax ID. [1] [2]
What does the Payment Regime field in the DGII lookup mean, and does it affect my obligations when paying that supplier?
The Payment Regime field shows whether a supplier is in the ordinary regime, which the portal shows as NORMAL, or in the Régimen Simplificado de Tributación (RST), the simplified regime under Decree 265-19, which determines income tax and ITBIS on the basis of gross income or purchases. The RST classification has a direct impact on buyers: the DGII states that individuals and companies buying from suppliers in the RST must withhold 100% of the ITBIS invoiced and pay it to the DGII. Law 30-26 (18 June 2026) creates a new simplified regime, with income ceilings of RD$30 million or RD$15 million and a purchases ceiling of RD$60 million depending on the modality, but it applies only once its implementing regulation is issued. Checking the regime field before processing payment prevents incorrect ITBIS treatment and potential penalties. [1] [2] [3] [4]
Does having an RNC automatically mean a company is registered for ITBIS (the Dominican VAT equivalent)?
There is no separate ITBIS registration step. When an entity registers in the RNC it declares its economic activities, and the DGII assigns its tax obligations from those activities; the DGII RNC guide says these obligations are activated automatically. An entity is an ITBIS taxpayer when its declared activities involve taxed transfers of goods, imports or taxed services, and there is no minimum-revenue threshold. The DGII RNC lookup does not return a dedicated ITBIS-registered field. The closest proxy is the Economic Activity field, which shows whether the declared business involves goods or services subject to ITBIS at 18%. [1] [2]
Does a foreign company operating in the Dominican Republic need its own RNC, and what is the process?
Yes, if it carries on business in the Dominican Republic through a local company or a branch. The DGII requires a foreign company (sociedad extranjera) to have its constitutive documents translated into Spanish, apostilled and registered at the Chamber of Commerce, and then to apply for the RNC with Form RC-02. For ITBIS, Title III of the Tax Code treats Dominican and foreign persons alike, with no registration threshold. There is no ITBIS registration scheme for foreign suppliers that only sell remotely. When a Dominican business pays a non-resident Dominican-source income, it withholds income tax and issues a Pagos al Exterior receipt (e-CF type 47); from 1 July 2026 the withholding on software licences, online advertising and data use or storage is 15% (Law 30-26). [1] [2] [3] [4]
What does 'Estado: Suspendido' mean in the DGII lookup, and can I safely pay or accept invoices from a suspended RNC holder?
Suspendido means the DGII has administratively suspended the taxpayer's RNC, most commonly because they have not filed tax returns for 18 or more consecutive months. A suspended entity cannot obtain new fiscal receipt sequences from DGII. To reactivate, the taxpayer files its outstanding returns for the last three years; the DGII help centre says no penalty fee applies and reactivation is automatic the next business day. A Dado de Baja status means the RNC has been deregistered, but a Dado de Baja Administrativa status is not necessarily final: the DGII help centre explains that the taxpayer first updates its RNC, which moves it to Suspendido, and then files three years of returns to reactivate it. [1] [2]
How does the RNC connect to the Dominican Republic's e-CF electronic invoicing mandate, and what does the 'Electronic Billing' field in the DGII lookup mean?
The Electronic Billing field shows whether the taxpayer is authorized to issue e-CF (Comprobantes Fiscales Electrónicos), which carry the issuer's RNC and an e-NCF sequence assigned by the DGII. Each taxpayer group has its own deadline: for example, large local and medium taxpayers that were already implementing had until 15 November 2025, and may use paper B receipts until 31 October 2026, so a paper invoice is not by itself a sign of non-compliance; the Dominican Republic ITBIS guide on Lookuptax has the full timeline. [1] [2] [3]
When paying a Dominican supplier, does verifying their RNC status affect the withholding tax rates I must apply?
Yes. Whether you withhold ITBIS, and how much, depends on the supplier's status and regime: for example, 100% on purchases from RST suppliers, and, since 16 September 2026, no Norma General 02-05 withholding when a company supplier is an authorised e-CF issuer invoicing with an e-CF (Norma General 02-2026). The Dominican Republic ITBIS guide on Lookuptax sets out every withholding case, the card-payment rules and the income-tax withholding on payments to non-residents. [1] [2] [3]
