Provisional NIF vs permanent NIF: what the difference actually means.

Most founders receive a provisional NIF when the company is first incorporated. Knowing what it covers — and what it does not — prevents compliance gaps in the first operating months.

Your Spanish company won't incorporate itself ↗ Tax activation handled as one sequence

Stage 1 — Provisional

B — ————————

Issued within days of incorporation on submission of Modelo 036. Invoicing, contracts and starting the bank onboarding are possible. Certain tax procedures remain restricted.

Stage 2 — Permanent

B — ————————

Same number, confirmed status. Issued once the Agencia Tributaria has verified the registered deed, address and operational reality of the company.

The digits do not change. That is the part that catches founders out — a provisional NIF and a permanent NIF look identical on paper, so it is easy to assume the tax registration is finished when it is not.

Why Spain issues two versions of the same number.

The NIF (Numero de Identificacion Fiscal) is the tax identification number assigned to a Spanish company. Unlike the NIE, which belongs to an individual, the NIF belongs to the legal entity, and it appears in every tax filing, invoice, banking communication and piece of official correspondence.

Spain operates a two-stage NIF system for newly incorporated companies. The first NIF issued is provisional; a permanent NIF follows once the company has completed additional steps with the Agencia Tributaria. The number itself is the same in both cases. The distinction lies in the status of the company's registration and the range of operations it can formally conduct.

The provisional NIF: what it covers.

The provisional NIF is issued by the Agencia Tributaria immediately upon incorporation, typically within days of the company being filed with the Commercial Registry. It is assigned on submission of Modelo 036 — the basic tax registration form — and it allows the company to begin operating in a limited capacity. It carries the letter B followed by eight digits for Spanish limited entities, and that format is retained when the NIF becomes permanent; only the internal classification within the Agencia Tributaria changes.

Operation	Provisional NIF	Permanent NIF
Issue invoices	Yes	Yes
Enter into contracts	Yes	Yes
Start bank account onboarding	Yes	Yes
Complete bank account activation	Often deferred by the bank	Yes
ROI / intra-community VAT number	Confirmed NIF required	Yes
Full range of tax procedures	Restricted	Yes

Converting to a permanent NIF.

To convert from provisional to permanent status, the company must give the Agencia Tributaria evidence that the entity is genuinely operational. Until that confirmation, the company's tax profile stays in a preliminary state — which affects certain administrative interactions and creates ambiguity in third-party systems.

Day 0

Incorporation and Modelo 036The escritura is signed and the initial tax registration is filed. The provisional NIF is issued, usually within days.

Weeks 1-6

Registration at the Commercial Registry completesThe deed is inscribed. The registered copy is the core document the Agencia Tributaria will want to see.

Supporting file

Address and activity evidenceProof of a registered office or physical address in Spain and, in some cases, evidence of economic activity.

Target: within 3 months

Permanent NIF confirmedThe Agencia Tributaria reviews the file and confirms the NIF. Most companies should aim to close this within the first three months of incorporation.

Why Spanish banks reject foreign-owned companies ↗

Why this matters in practice.

The distinction between provisional and permanent NIF becomes relevant in three specific situations.

BankingSome banks flag companies on a provisional NIF during onboarding and ask for confirmation of permanent status before activating the account — delaying access if the conversion was never started.

VAT and invoicingCertain VAT procedures and intra-community registrations, including the ROI, require a confirmed NIF. Companies invoicing EU clients from day one should prioritise it.

Compliance profileSitting on provisional status for an extended period without follow-up creates an unclear tax profile that complicates later filings, audits and structural changes.

Tax and compliance setup in Spain ↗

Tax registration as a structured process.

The NIF confirmation is one element of a broader tax activation that every Spanish company should complete systematically after incorporation:

Modelo 036 finalised — activity codes, address and obligations correctly declared.
VAT registration where applicable, including ROI for intra-community trade.
Social Security setup for the director, according to the applicable regime.
Digital certificate activated, so the company can file and receive notifications electronically.

The takeaway

Handled as a coordinated sequence, this is quick. Left incomplete, each item becomes an obstacle.

None of these steps is difficult on its own. The failure mode is treating them as disconnected errands spread across months — by which point a bank, a client or a filing deadline has already run into the gap.
