Spanish subsidiary formation for foreign company

The Challenge

A US-based management consulting firm specialising in digital transformation had won a major contract with a European multinational that required operational presence in Spain. The deadline to be operational was 30 days — an extremely aggressive timeline considering that the standard incorporation of a company in Spain can take between 6 and 8 weeks for notarial and registry procedures alone.

Beyond corporate formation, the firm needed to open operational bank accounts, obtain the definitive tax identification number, register with Social Security, formalise 12 employment contracts compliant with Spanish labour law, lease and fit out offices in Madrid, and comply with all applicable tax and data protection obligations. The firm had no prior knowledge of the Spanish regulatory environment, no existing relationships with Spanish notaries, banks, or public administrations, and no Spanish-speaking staff. The 30-day constraint was not negotiable: the client contract contained a penalty clause tied to the start date.

Our Approach

The first decision was organisational: rather than working sequentially, we designed four parallel workstreams from day one, each led by a specialist team and reporting to a single project coordinator who held a daily standup with the US firm’s Managing Partner. This structure meant that while the legal team was filing with the notary, the tax team was already processing registrations, the labour team was drafting contracts, and the office search was underway simultaneously.

Legal workstream: entity formation. We used the express limited company (sociedad limitada exprés) procedure under Royal Decree-Law 13/2010, which allows incorporation using standard articles of association approved by the Consejo General del Notariado. By adopting the standard articles without modifications, we avoided the custom drafting review period and reduced notarial processing time. Share capital was set at the statutory minimum to avoid delays from capital verification requirements. The commercial registry inscription, which is the step that most commonly adds two to three weeks in standard incorporations, was expedited through direct liaison with the Madrid registry. The company received its provisional tax identification number on day two and its definitive NIF on day nine.

Tax workstream: registrations and compliance setup. While the legal team handled incorporation, our tax team simultaneously filed the census declaration (Modelo 036), obtained the VAT registration number, and set up the electronic notifications mailbox with the Spanish Tax Agency. We configured the company’s accounting system in compliance with the Spanish General Chart of Accounts (Plan General Contable) and established the quarterly VAT reporting calendar and the corporate income tax provision schedule. A Transfer of Assets and Economic Activities notification to the Madrid regional government was filed on day fourteen.

Labour workstream: employment contracts and Social Security. The firm’s twelve planned hires included senior consultants, project managers, and two operations roles. We identified that the applicable collective bargaining agreement was the national consulting sector agreement (Convenio Colectivo Estatal de Empresas Consultoras). We prepared twelve bespoke employment contracts, including two executives with enhanced termination provisions and non-compete clauses. All twelve employees were registered with Social Security by day twenty-two. We also configured the payroll processing system, set up the company’s SILTRA connection for monthly Social Security filings, and calculated the first month’s payroll provisions.

Business services workstream: office and data protection. In parallel with the regulatory workstreams, we coordinated the search and signing of a two-year office lease in the Paseo de la Castellana business district, utility connections, and basic fit-out. We also implemented a GDPR-compliant data protection policy adapted to the firm’s service model, prepared the records of processing activities required under Article 30 of the GDPR, and configured a cookie consent framework for the Spanish microsite.

Results

The Spanish subsidiary became fully operational in exactly 30 calendar days, with all 12 employees registered, three active bank accounts across two financial institutions, and zero regulatory incidents during the first six months of operation. The client contract commenced on schedule, avoiding the penalty clause and generating first-month revenues that covered the full cost of the establishment exercise.

The documentation and process playbook developed during this engagement — incorporating checklists, template contracts calibrated to the consulting sector agreement, standard GDPR policies, and a step-by-step registry and Social Security guide — was subsequently used by the US firm to replicate the model in two additional European markets, with BMC providing remote guidance for each.
