Register a Company in Madrid: The Honest 2026 Guide

If you want to register a company in Madrid, you have picked the city where Spain actually does business, but almost nobody explains the process in plain English before you are sitting in front of a notary. Madrid is Spain’s capital and its financial centre, so the bilingual lawyers, gestores, accountants and banks who already understand foreign founders are what makes the paperwork survivable. This guide covers the Registro Mercantil process, the 2026 corporate tax rates, what a notary and gestor actually do, realistic costs and timelines, and the VAT and Social Security registrations that trip people up. This is general information, not legal or tax advice, so confirm your own situation with a licensed professional before you sign anything.

Why Founders Register a Company in Madrid

Most international founders who register a company in Madrid do it for critical mass. Madrid hosts Spain’s stock exchange, the head offices of most major banks, and the Registro Mercantil Central, the national body that manages company names for the whole country. That means the professional services you need, notaries used to foreign paperwork, English-speaking gestores, and bank branches used to non-resident directors, already exist here at scale.

You can incorporate anywhere in Spain and run the business from Madrid, or the reverse. But if you plan real substance, an office, staff and genuine local management, Madrid is usually where that ecosystem already sits.

The Registro Mercantil Process, Step by Step

Spain forms companies through a national system, but your deed is registered provincially at the Registro Mercantil de Madrid. Most founders who register a company in Madrid choose a Sociedad Limitada (SL), the local equivalent of an Ltd.

1. Reserve the name. Request a certificación negativa de denominación social from the Registro Mercantil Central, with two or three backup names. The reservation is valid for a limited period, so move quickly once it is issued.
2. Get a NIE if you are a foreign founder. Any non-Spanish shareholder or director needs a Número de Identificación de Extranjero before a notary will sign anything. Start this early through a Spanish consulate abroad or an immigration office, since it is often the slowest step.
3. Deposit the capital. Under the traditional route, your bank certifies the capital is deposited. Since the 2022 Ley Crea y Crece reform, an SL can technically be formed with 1 euro, though most founders deposit a working amount.
4. Sign the escritura pública. A Spanish notary drafts and signs the public deed with the founders, covering bylaws, directors, registered office and shareholding.
5. Register at the Registro Mercantil de Madrid. Your gestor requests a provisional NIF from the Agencia Tributaria via Modelo 036, then files the deed for inscription at Príncipe de Vergara 72, 28006 Madrid, phone 91 576 01 17.

Founders using standard, ministry-approved bylaws with capital under 3,100 euros can file through CIRCE instead, a single Documento Único Electrónico that reaches the notary, the tax office, the registry and Social Security in one pass. Gestorías report a straightforward CIRCE filing can be signed and registered within a few business days, while a bespoke deed through the ordinary route more often takes one to three weeks. Confirm current timing with your notary or gestor before committing to a date.

2026 Corporate Tax: The 25% Rate and the New-Company Discount

The number every founder needs before they register a company in Madrid: the general corporate tax rate for 2026 is 25%. That is what an established, profitable SL pays.

The useful exception is for newly created companies. An “entidad de nueva creación” pays a reduced 15% in its first tax period with a positive taxable base and in the following period, provided it is not part of a corporate group and does not simply continue a pre-existing activity under a new name. Company formation itself, plus capital increases and partner contributions, is exempt from Transfer Tax and Stamped Legal Documents duty (ITP/AJD), so incorporating carries no separate tax bill. Get proper advice from a Spanish tax adviser before you file anything.

Costs and Timelines to Register a Company in Madrid

Official fees and professional fees get confused constantly when you register a company in Madrid. With standard bylaws and capital of 3,100 euros or less through CIRCE, the notary’s fee is fixed at 60 euros and the Registro Mercantil de Madrid charges 40 euros, both set by official tariff. Outside that scheme, the standard telematic notary fee is around 150 euros plus 100 euros for the registrar.

Professional fees are the real spend. A gestor who manages the whole process, name reservation, NIE help, drafting and registration, typically charges a few hundred to around a thousand euros, plus ongoing monthly accounting once you trade. Budget separately for a corporate bank account, often the slowest step since Spanish banks apply strict source-of-funds checks.

VAT and Social Security After Incorporation

Incorporation is only half the job. Before your first invoice, file Modelo 036 with the Agencia Tributaria to register your activity and get your definitive NIF. Spain has no minimum turnover threshold for VAT, so you register for IVA in that same filing, from your first sale. The standard VAT rate is 21%.

If the company employs anyone, including an active director, register as an employer with the Tesorería General de la Seguridad Social for a Código de Cuenta de Cotización, then affiliate each worker through Sistema RED before they start. A director who actively works in the company usually registers under the self-employed regime (RETA) instead of as a standard employee, at a monthly quota that depends on real net income, so check current bands on sede.seg-social.gob.es rather than an old figure.

Many founders who register a company in Madrid keep day-to-day payments on a multi-currency account such as wise.com or revolut.com alongside their Spanish business bank account, since both simplify cross-border invoicing while you build a local banking relationship. If dealing with a notary in Spanish feels daunting, a few sessions on italki.com before appointments genuinely help, and if you are relocating to run the company yourself, sort your own health cover early through a provider such as ektatraveling.com rather than leaving it until you are already busy trading.

Frequently Asked Questions

How long does it take to register a company in Madrid?

Using standard bylaws through CIRCE, a straightforward incorporation can often be signed and registered within a few business days. A bespoke deed through the traditional route more commonly takes one to three weeks once the registry queue is factored in, so confirm current timing with your notary or gestor.

What is the corporate tax rate in Spain in 2026?

The general rate is 25%. Newly created companies pay a reduced 15% in their first profitable tax period and the following one, provided they meet the conditions for an entidad de nueva creación.

Do I need a notary to register a company in Madrid?

Yes. A Spanish notary must draft and sign the escritura pública, so this step is not optional. Most founders also use a gestor to handle the name reservation, NIE help and registry filing around that appointment.

How much capital do I need to register a company in Madrid?

Since the 2022 Ley Crea y Crece reform, an SL can technically be formed with as little as 1 euro. Below the traditional 3,000-euro threshold, the company must allocate 20% of annual profits to a legal reserve until capital plus reserve reach 3,000 euros, so most founders still deposit a meaningful working amount.

When do I need to register for VAT after I register a company in Madrid?

Spain has no turnover threshold before VAT registration. You register for IVA as part of the same Modelo 036 filing you submit before issuing your first invoice, and the standard VAT rate is 21%.
