How to Get a NIF in Portugal

Obtaining a NIF involves the assignment of a Portuguese tax identification number by the Portuguese Tax and Customs Authority based on the identification, address and other information required for the applicant’s circumstances.

The documentation and available administrative channels may differ depending on the applicant’s circumstances and whether the request is handled directly or through a representative.

If you are new to the topic, more information is available on what a NIF is in Portugal.

Where Can You Apply for a NIF?

NIF requests may be handled through Portuguese Tax and Customs Authority service points and other public service locations where the relevant tax service is available.

Depending on the applicable procedures and the applicant’s circumstances, a request may also be handled through a representative using administrative channels made available by the Tax Authority.

Available channels, appointment arrangements and the services provided at individual public service locations may vary.

What Documents Are Usually Required?

The documentation required for a NIF depends on the applicant’s circumstances and the information that must be registered with the Portuguese Tax and Customs Authority.

For residents

Applicants resident in Portugal may be required to provide valid identification and documentation supporting the address or other registration information relevant to their circumstances.

For non-residents

Non-resident applicants may be required to provide valid identification and documentation supporting their foreign address or other relevant registration information.

Additional requirements may apply depending on tax residence, the rules in force, available notification mechanisms and the applicant’s individual circumstances.

Do You Need a Fiscal Representative?

Fiscal representation requirements for non-residents depend on tax residence, the applicable rules, available electronic notification mechanisms and the individual circumstances.

A fiscal representative acts in relation to the taxpayer’s obligations and communications with the Portuguese Tax and Customs Authority within the scope established by the applicable rules.

The requirement should not be inferred solely from nationality or from the fact that an applicant has an address outside Portugal.

Can You Get a NIF Online?

The administrative channels available for NIF requests depend on the applicant’s circumstances and the procedures made available by the Portuguese Tax and Customs Authority.

In some circumstances, a representative may be able to submit a request through electronic channels provided by the Tax Authority. This is different from assuming that a universal online self-service application is available to every applicant.

Available procedures and identification or documentation requirements may change over time.

How Long Does It Take to Get a NIF?

There is no single processing time that applies to every NIF request.

The time required can depend on the administrative channel used, appointment availability, documentation and whether additional information or verification is required.

Requests handled through different channels or through a representative may therefore have different processing times.

Is There a Cost to Get a NIF?

The assignment of a NIF by the Portuguese Tax and Customs Authority should be distinguished from any professional or administrative services used in connection with the process.

Where a representative or private service provider is involved, professional or service fees may apply depending on the provider and the scope of the service.

When a NIF May Become Relevant

A NIF is used across many tax, financial and administrative contexts in Portugal and may become relevant at different stages depending on the person’s circumstances.

Examples can include banking, contracts, property transactions, employment, invoicing and dealings with the Portuguese tax authorities.

More information about the contexts in which the number may be relevant is available on whether you need a NIF in Portugal.

Can You Request a NIF Together With Other Numbers?

Certain integrated public-service channels may allow eligible applicants to deal with more than one identification or registration process, which can include tax, social security or health-related registration.

The services available depend on the specific public-service channel, the applicant’s eligibility and the procedures in force. The availability of several public services at a particular location does not necessarily mean that all identification numbers can be requested together in every case.

When Professional Support May Be Useful

This page explains in general terms how NIF applications may be handled in Portugal. It does not assess individual eligibility, confirm documentation or determine whether fiscal representation is required in a particular case.

Qualified independent professionals may, within their respective areas of competence and depending on the circumstances, provide support in relation to matters such as documentation, fiscal representation or administrative requirements connected with tax, relocation or other processes.

Portugal Vista provides general information and may, where appropriate, connect readers with qualified independent professionals. Professional services are provided directly by the relevant professionals.

Frequently Asked Questions

The questions below address practical points about obtaining a NIF in Portugal. They complement the sections above and focus on common situations and administrative requirements.

Can someone apply for a NIF on my behalf?

A NIF application may be submitted through a representative where the applicable procedure and documentation allow it. The exact requirements depend on the applicant’s circumstances and the administrative channel used.

What happens if I do not have all the required documents?

Missing or incomplete documentation can prevent the request from being completed or require additional information before the NIF can be assigned.

Can a NIF be issued on the same day?

Processing times vary depending on the administrative channel, appointment arrangements, documentation and whether additional information or verification is required.

Can I use a foreign tax number instead of a NIF?

A foreign tax identification number does not replace a Portuguese NIF where a Portuguese NIF is required for a particular tax or administrative purpose.

Do I need a Portuguese address to get a NIF?

Non-residents may obtain a NIF using foreign address information. Any additional requirements, including fiscal representation requirements, depend on tax residence, the applicable rules, available notification mechanisms and the individual circumstances.

Can I update my NIF details later?

Information associated with a NIF, such as address, contact or other registration information, may be updated where applicable in accordance with the procedures of the Portuguese Tax and Customs Authority.
