What is your Tax ID in the Dominican Republic? | RNC

By Easyco Updated October 10, 2026

The tax ID in the Dominican Republic is the RNC (Registro Nacional de Contribuyentes), issued by the tax administration, the Dirección General de Impuestos Internos (DGII). Every company needs one: it identifies the company on every invoice, tax return and bank document.

The Dominican Republic, a Caribbean country with free trade access to the United States and its regional neighbors through CAFTA-DR, also offers tax incentives that attract foreign companies.

What is an RNC?

The RNC is the number that identifies taxpayers in the Dominican Republic. Companies receive a 9-digit RNC; individuals use their cédula number as their taxpayer ID. The company needs it to issue tax receipts (e-CF electronic invoices), file returns, hire staff and open a corporate bank account.

How to obtain an RNC?

The RNC is the last formal step of company formation. Once the company is registered in the Mercantile Registry of the local Chamber of Commerce, it applies to the DGII, through the DGII’s online portal (Oficina Virtual) or the Formalízate one-stop portal (formalizate.gob.do).

What documents are required to obtain an RNC in the Dominican Republic?

The Mercantile Registry certificate
The bylaws and the minutes appointing the managers or directors
The trade name certificate from ONAPI
Proof that the incorporation tax was paid
IDs or passports of the shareholders and the legal representative
Proof of the company’s address

What government agency issues it?

The DGII, which belongs to the Ministry of Finance and Economy, issues the RNC and administers internal taxes such as income tax and ITBIS (VAT).

Is it necessary to have a registered company in the Dominican Republic to obtain an RNC?

For a company, yes: the RNC is issued to the registered legal entity, so the company must be formed first. In short, the order is:

Choose the type of company; most foreign founders use the S.R.L.
Register the trade name with ONAPI.
Sign the bylaws and pay the incorporation tax to the DGII.
Register the company in the Mercantile Registry.
Obtain the RNC from the DGII.
Open a corporate bank account.

After you get the RNC

The company starts filing monthly ITBIS and withholding returns and an annual income tax return, and issues electronic tax receipts. See accounting and tax in the Dominican Republic.
