Documents to Work in Mozambique: NUIT, BI, and INSS

When you arrive at the interview or sit down to sign your first contract, the employer will ask for documents to work in Mozambique. The full list — and the nuances that separate "yes" from "almost" — is what this guide from Inademy's Guide explains: the Identity Card (BI), the NUIT, INSS registration, and the dossier you should have ready.

The goal is simple: on hiring day, you are not looking for a document. You have everything organized and sign with steady hands.

The short answer: what you need

• Identity Card (BI) — the centerpiece. Without a valid BI, most of the process stalls.
• NUIT — the Single Tax Identification Number, mandatory for all taxpayers in Mozambique, used in bank accounts, tax returns, and transactions.
• INSS — it is not a document you "have"; it is the registration made by the employer upon hiring. Your role is to monitor it and keep the proof.
• CV and educational certificates — proof of what you know how to do and where you studied.
• Proof of residence — several banks and employers request it; some with a recent date (Standard Bank asks for less than 60 days).

The Identity Card (BI): the key to everything

The BI is the document recognized by law as proof of citizen identity. It is at the root of almost everything: opening a bank account, obtaining a NUIT, signing a contract, registering with the INSS. The process falls under the competence of the Ministry of Interior, through the Civil Identification services.

• The regulation was updated by the Council of Ministers in June 2026: the standard is the Civil Identification and National Citizen Identity Card Regulation, approved by Law No. 6/2022 of June 20.
• What to bring to the application: birth registration details and the items requested by the local office — requirements may vary by post, so confirm with your province's Civil Identification office before going.
• If you lost your BI: the first step is to report the loss and start the replacement process at the competent service. Issuance time varies; in the meantime, proof of application works in some institutions (Banco MAIS, for example, accepts the BI application receipt for account opening).

The NUIT: the number the State gives you

The Single Tax Identification Number (NUIT) is assigned to each taxpayer — individual or legal entity — and is mandatory for taxpayers. In practice, it is one of the codes requested when opening a bank account, filing tax returns, or conducting formal transactions.

• Where to get it: at the Tax Area Directorates (DAF), collection posts, and other locations indicated by the AGT (General Tax Authority). The process can also be started on the official AGT website.
• What to present: BI (or passport, Birth Certificate, Voter Card, or DIRE, depending on the situation), proof of residence, and, if applicable, proof of economic activity.
• Official search: the portal nuit.at.gov.mz allows you to print the NUIT letter and check your registration status — if you have questions about your number, that is where you check.

A practical point: if you already have an active bank account, your NUIT likely already exists. Ask for it at the bank or on the portal — and if you don't have one, apply for it now, because it will be requested for your first contract.

The INSS: who registers, who monitors

Registration with the National Social Security Institute (INSS) is the employer's obligation upon hiring — it is not a candidate's task. What the candidate does is different, and important.

• Ask for proof of registration. When you sign, ask: "when will I be registered with the INSS and what is my taxpayer number?" The answer should be clear.
• Keep every pay slip. The pay slip shows the INSS deduction. It is your concrete proof — and the basis for any future contribution verification.
• Monitor on official platforms. The INSS provides channels (SISSMO, M-Contribuição) to check your status. The full guide is in the INSS in Mozambique guide.
• If the employer does not register you: it is a violation — the guide on where to report explains the official channels.

The first-day dossier

Organizing your documents before your first day changes the outcome. The practical list, in the order you should have everything ready:

1. Updated CV — the CV for a first job guide solves the blank page issue, even without work experience.
2. Educational certificates — school or training documents. If a certificate was lost, the records office of the original institution issues a replacement certificate.
3. BI and NUIT — the two numbers that identify you to the state and tax authorities.
4. Recent proof of residence — some employers and banks ask for it; the published standard is less than 60 days, as requested by Standard Bank.
5. Written contract — signed and dated, with clear conditions, within the rights guaranteed by law (the practical list guide on workers' rights summarizes them). Keep two copies: yours and the employer's.

Common mistakes in your first hiring process

A ready dossier is not enough if there are gaps in the process. These are the mistakes that cost the most in the first few months.

• Signing a blank contract. If the document does not include the negotiated terms, do not sign it. What is promised in the interview is only valid when on paper.
• Not asking for your INSS contributor number. It is your right to know what it is and when it was created. Ask for it upon signing — it is the simplest question to ask, and the one most employers answer poorly.
• Handing over your BI without a record. Many employers ask to see it and keep it: hand over the BI and record the date; its return is your right, not a courtesy on their part.
• Not having digital copies of anything. Losing a document and waiting for a replacement delays your first day; a copy saved on your phone solves most emergencies.

A dossier of documents to work in Mozambique is not a package you close and forget: it is a process. If something doesn't add up, the problem is rarely yours — it's missing information. Ask in writing and keep the response.

If you are a foreign national

The framework changes. A resident foreigner's documents include the DIRE (Foreign Resident Identification Document) and, in many cases, a valid work permit.

The DIRE is accepted in procedures such as obtaining a NUIT and opening bank accounts (BCI, for example, accepts a passport or DIRE, according to its public materials). Before signing, confirm with the employer and the Labor Inspectorate what exact regulations apply to your situation.

Keeping your dossier updated

Documents are not a one-time event — they are a routine. Three habits make the difference:

• Update your information. Changed your address or phone number? Inform your bank, the INSS, and employers. Banks request updated data as part of anti-money laundering measures.
• Digital and physical copies. Secure photos or scans on your phone and a paper copy. Digital for emergencies, physical for the dossier.
• Check validity. The BI has an expiration date — check the date before it expires and renew in advance.

Frequently asked questions

Do I need a NUIT to sign an employment contract?

The NUIT is mandatory for all taxpayers and appears on bank accounts and tax statements. Several employers and banks request it in the hiring dossier — in practice, obtaining it before signing your first contract is the safest choice.

I lost my BI. Can I work anyway?

It depends on the employer. Some accept proof of application for the BI initially; others require the document itself. The right step is to report the loss and start the replacement process at the Civil Identification service — and inform the employer about the status of the process.

Does the NUIT expire?

The number is an identifier assigned to you and stays with your registration status. Official verification can be done on the nuit.at.gov.mz portal — check your registration status there instead of guessing.

Is INSS registration my responsibility?

No — it is the employer's obligation upon hiring. Your role is to ask for proof of registration, keep the receipts, and monitor your status on official platforms. If you are not registered, report it: the guide on where to report explains the channels.

What documents does a resident foreigner need?

The DIRE is the centerpiece — it is accepted in procedures like obtaining a NUIT and opening a bank account. To work, a valid work permit may be required: confirm with the employer and the Labor Inspectorate what exact regulations apply to your situation.

In summary, what to do today

1. Valid BI — the key to all doors.
2. NUIT obtained — at the DAF, collection post, or the AGT portal.
3. INSS — ask your employer for proof of registration and keep every pay slip.
4. CV and certificates — without them, your application remains incomplete.
5. Recent proof of residence — Standard Bank, for example, requires a date under 60 days old.
