NIF for companies in Portugal

The company number, in plain terms

NIPC stands for Número de Identificação de Pessoa Coletiva, which translates as identification number for a collective person. In practice, everyone just says NIPC, and many people also call it the company NIF, because it does the same job for a company that a personal NIF does for a person. It identifies the company to the tax authority, and it appears on the company's invoices, contracts, tax returns, and bank file.

The NIPC does double duty. It is the company's registration number with the commercial registry and its tax number with Finanças at the same time. There are not two separate numbers issued by two offices. One number covers both roles, which is why banks and accountants ask for the NIPC before they ask for anything else about the company.

The number is nine digits long, like a personal NIF, and company numbers start with 5. That first digit is how the system tells a company apart from a person at a glance. Like a personal NIF, the NIPC is permanent. It stays with the company for its whole life, and it does not change if the company moves address or changes directors.

Personal NIF versus company NIPC

The confusion here is understandable, because both numbers are nine digits and both are often called a NIF. The difference is whose number it is. A personal NIF belongs to a human being. A NIPC belongs to a company. A company cannot borrow its founder's personal NIF for company business, and a founder cannot use the company NIPC for personal business. Each side of the line has its own number, and the tax authority keeps them separate.

Personal numbers first, company second

This is the step that delays more incorporations than any other. Every shareholder and every director must hold a personal NIF before the company can be registered. That includes non-resident foreigners, and it includes every person named in the file, not just the founder. If one shareholder is still waiting on a personal NIF, the whole incorporation waits with them.

The practical consequence is simple. Apply for the personal numbers weeks before you plan to incorporate, not in the same week. The online route for a personal NIF takes a few working days once documents are accepted, and a rejected document can add another round of days. Our guide to getting a NIF online walks through the filing, and our NIF documents checklist covers what each applicant needs. If you are applying from abroad, read the representative rules too, because a non-resident founder often needs one for the personal number even though the company itself will have a Portuguese registered address.

When a shareholder is itself a company rather than a person, the file needs that company's own paperwork instead: its certificate of incorporation, its articles, and proof of who its current directors are. Documents issued abroad usually need a Hague apostille, and a certified translation if they are not in Portuguese. Our documents guide explains the translation and authentication rules that apply to foreign paperwork.

How the company number is issued

The NIPC is not applied for separately. It is assigned as part of incorporation, when the company is registered with the commercial registry. You choose the route, you file the company, and the number comes out of that same process, together with the company's permanent registration certificate. There is no separate NIPC application form to fill in afterwards.

Empresa na Hora, which means company on the spot, is the fastest route, and it suits founders who are happy with a standard company shape. You go to a registry desk, pick from pre-approved names and articles, and the company is created in under an hour. The trade-off is flexibility. If you need a custom name, bespoke governance rules, or unusual share classes, the traditional route through a lawyer or notary is the honest choice, and it takes one to two weeks. The online route sits between the two: you request a name certificate first, then file through the government business portal.

Whichever route you take, the same building blocks are needed: a company name, a registered office address in Portugal, the articles of association, the share capital, and the personal NIFs of everyone named. The most common company form, the sociedade por quotas, or Lda, needs no fixed minimum capital beyond €1 per share, and it can have a single shareholder. A larger sociedade anónima, or SA, needs at least five shareholders and €50,000 of share capital. The number itself costs nothing extra on any route. You pay the registration and professional fees, not a fee for the NIPC.

What happens after the number arrives

The NIPC is the start of the company's administrative life, not the end of it. Within 15 days of incorporation, the company must file its declaration of start of activity with Finanças, a form that has to be signed by a certified accountant. That declaration tells the tax authority what the company does and which tax regimes apply to it. It is also the step where VAT registration is handled, which matters because holding a NIPC alone does not register the company for VAT.

Within 30 days, the company and its directors must be registered with Social Security, and the company's beneficial owners must be registered too. The company also needs a business bank account, and banks will ask for the NIPC, the incorporation documents, and the identification of the directors and shareholders before they open it. Our bank accounts guide covers what Portuguese banks ask for in general, and the company file is stricter than a personal one, so expect the bank to ask about beneficial ownership as well.

One more distinction is worth making clearly. A NIPC on its own does not prove that a company pays tax in Portugal or that it is trading. It proves the company is registered. Ongoing tax duties depend on what the company actually does, not on holding the number. A dormant company and an active one hold the same kind of number, and only the filings tell them apart.

The sole trader exception

Not every business gets a NIPC. A sole trader, known in Portugal as an empresário em nome individual, trades under their own name and their own personal NIF. There is no separate company to number, so there is no NIPC. The trader registers the activity under the personal number and issues recibos verdes, the green receipts, against it. If you are choosing between trading as a sole trader and forming a company, this is one of the real differences: the company gives you a separate legal person with its own number, and the sole trader route keeps everything under your own number, with personal liability for the business.

The cost picture follows the same split. The personal number itself is free, and our NIF cost guide adds up what each personal route really costs, including renewals. The company number is also free in itself, and what you pay for is the incorporation around it. Price the whole route, not the number, in both cases.
