SL vs Startup Law certification: it is not a different legal form — it is a certification that unlocks tax benefits on your existing SL

Comparison between a standard Spanish limited company and certification as an empresa emergente under Spain's Startup Law. 15% corporate tax, stock options, Beckham and eligibility requirements in 2026.

Standard SL (Sociedad Limitada)

Advantages

  • ✓ Proven legal structure with no restrictions: any lawful economic activity, no innovation requirement, no additional certification
  • ✓ No age or revenue limits: can operate indefinitely at any revenue level without losing its status
  • ✓ No annual certification burden: no obligation to prove innovative character to any authority each year
  • ✓ Total activity flexibility: can change sector, business model or activity without losing any benefit
  • ✓ Universal structure for any size: from a one-person micro-enterprise to a multinational group

Disadvantages

  • ✗ Corporate income tax at 25% (23% for companies billing under EUR 1M), with the 15% reduced rate applying only for the first two profitable years — no extension
  • ✗ No special stock option regime: share options are taxed as employment income at the moment of exercise, with no deferral mechanism
  • ✗ No access to the expanded Beckham Law provisions: foreign talent recruited by the company cannot benefit from the impatriate regime extension provided under the Startup Law
  • ✗ No fast-track procedures at public registries or reduced notarial and registry fees

Empresa Emergente (Law 28/2022 — Spanish Startup Law)

Advantages

  • ✓ Corporate income tax at 15% for the first four profitable years (versus 25% in general, or 15% for only two years under the standard SL regime)
  • ✓ Deferred stock option tax regime: taxation deferred until the sale of shares, with exemption of up to EUR 50,000 per employee per year (expanded from the previous EUR 12,000 ceiling)
  • ✓ Extended access to the Beckham Law: the impatriate regime can apply not only to founders who relocate to Spain but also to highly qualified workers recruited by the startup
  • ✓ Corporate income tax payment deferral without interest or guarantees for the first two years with a positive tax base
  • ✓ Reduced notarial and registry fees on incorporation: lower formation costs from day one
  • ✓ Fast-track administrative procedures: the Law establishes reduced timelines for online incorporation and a single-window access point

Disadvantages

  • ✗ Innovative character requirement: the company must develop an innovative entrepreneurship project — ENISA evaluates the innovative nature and can deny or revoke certification
  • ✗ Age limit: only companies under 5 years old qualify (7 years in biotechnology, energy, industry and other strategic sectors)
  • ✗ Revenue ceiling: the company loses its emergent status when it exceeds EUR 10 million in revenue or ceases to meet the innovation requirement
  • ✗ Mandatory annual certification: the company must demonstrate to ENISA each year that it maintains the innovative character and other requirements
  • ✗ Cannot have distributed dividends or be listed on a regulated market to access the regime

Our verdict

If your company qualifies as innovative and is under 5-7 years old, the Startup Law benefits are substantial. The 15% corporate tax rate for four years instead of two, and the stock option deferral regime up to EUR 50,000 per employee, are the two most financially significant advantages. A critical clarification: the empresa emergente is not a separate legal form — it is a certification awarded on top of an existing SL (or SA). Registering as an empresa emergente makes your SL a company with additional benefits, not something different from an SL. If your company does not qualify or has already exceeded the age or revenue thresholds, a standard SL with proper tax planning remains the optimal structure for operating in Spain.

The conceptual mistake founders make about the Startup Law

When founders ask “should I set up an empresa emergente or an SL?”, the question contains a false premise. An empresa emergente IS an SL — Law 28/2022 does not create a new legal form. It grants an innovative character certification on top of an already-incorporated company (typically an SL) that unlocks a specific set of tax benefits.

The right question is: “Should I apply for empresa emergente certification for my SL?” And the answer depends on whether you meet the requirements and whether the benefits justify the cost of certification and ongoing status maintenance.

The concrete benefits: with numbers

15% corporate tax for four years vs two

A standard SL pays corporate income tax at 15% only for the first two profitable years. From year three, the rate rises to 25%. An empresa emergente maintains 15% for four years.

For a company with EUR 200,000 in profit in years 3 and 4:

ScenarioYear 3Year 4Cumulative saving
Standard SL (25%)EUR 50,000EUR 50,000—
Empresa emergente (15%)EUR 30,000EUR 30,000EUR 40,000

A EUR 40,000 saving in corporate tax in just two additional years of reduced rate. For companies with higher profitability, the saving scales proportionally.

Stock options: the structural benefit for talent attraction

The stock option regime before the Startup Law had two critical problems: taxation occurred at the moment of exercise (when the employee had not yet sold the shares and might lack the liquidity to pay the tax), and the maximum exemption was only EUR 12,000 per year.

The Startup Law resolves both:

  1. Deferral until sale: the employee does not pay tax on exercise, only when they sell the shares and have the cash. This eliminates the problem of being taxed on illiquid wealth.
  2. EUR 50,000 exemption: the first EUR 50,000 of gain per employee is exempt from both income tax and social security contributions each year.
  3. Capital gains taxation: gains above EUR 50,000 are taxed at 21-26% (capital gain rate) rather than at 37-47% (employment income rate).

The requirements: what the law demands

To be recognised as an empresa emergente, the company must simultaneously meet:

  • Innovation: developing an innovative entrepreneurship project with growth potential (assessed by ENISA)
  • Age: less than 5 years since incorporation (7 years in biotechnology, energy, industry and strategic sectors)
  • Size: annual revenue under EUR 10 million
  • No dividends: no profit distribution since incorporation
  • Not listed: not trading on a regulated market
  • Domicile: registered office or permanent establishment in Spain
  • No prior activity conversion: not created through merger, split or transformation of existing companies with equivalent activity

The innovation requirement is the most subjective and the one that results in the most application rejections. ENISA expects to see a differentiated, scalable business model with significant growth potential — simply being a traditional services company that uses technology is not sufficient.

How much does certification cost?

Direct costs are limited: the ENISA application fee is approximately EUR 250-500. The real cost is the specialist advisory fee for correctly preparing the innovation memorandum (EUR 500-2,000) and the annual renewal management.

The opportunity cost of not applying when requirements are met is far higher: for a company with EUR 300,000 in annual profit in years 3 and 4, the corporate tax saving from the two additional years at 15% amounts to EUR 60,000. The advisory cost to obtain the certification is recovered in the first quarter of the first profitable tax year.

Practical scenarios

Scenario A — SaaS company, 3 years old, EUR 800K ARR, EUR 150K profit: Applies for empresa emergente status. Saves EUR 15,000 in corporate tax in year 3 vs the standard SL rate. ENISA application well-justified by scalable software product. Certification recommended.

Scenario B — Professional services firm, 4 years old, EUR 5M revenue: Traditional services without a genuinely innovative component. ENISA application likely to be rejected or not recommended. Optimise within the standard SL regime.

Scenario C — Biotech startup, 6 years old, EUR 2M in grants and revenue: Qualifies under the 7-year extended age limit for biotechnology. EUR 50,000 stock option exemption highly relevant for scientific team retention. Certification strongly recommended.

FAQ

Frequently asked questions

ENISA (Empresa Nacional de Innovacion), under the Ministry of Industry, is the competent authority for evaluating and certifying the innovative character of companies applying for empresa emergente status. The application is made through the CIRCE platform at the time of incorporation, or separately if the company already exists. ENISA assesses the innovative value proposition, the business model and the project's scalability. The evaluation process typically takes 1-3 months. Certification is revocable if the company ceases to meet the requirements.
Article 14 of Law 28/2022 establishes three improvements over the general regime for share or participation grants to employees of empresas emergentes: first, income tax exemption of up to EUR 50,000 per employee per year (versus EUR 12,000 under the general regime); second, deferral of taxation until the moment of sale of the shares — the employee does not pay tax on exercise but when they sell and have the cash; and third, on sale, the gain is taxed as a capital gain (21-26% depending on the bracket) rather than as employment income (up to 47%). For a share option with a value of EUR 100,000, the difference in tax treatment can exceed EUR 25,000. The option plan must be authorised by the shareholders' meeting and beneficiaries must be employees under a labour contract.
The company automatically loses its empresa emergente status and, with it, future Startup Law tax benefits. This does not affect corporate tax already paid at the reduced rates — it only affects future tax years. If the company loses its status at year 4 by exceeding the revenue threshold, the two remaining years of 15% corporate tax (to complete the four-year benefit period) are forfeited and the company moves to the 25% rate from that tax year. Similarly for stock options: options exercised after loss of status fall under the general regime, losing the deferral and the EUR 50,000 exemption.
Yes, provided it meets all requirements at the time of application: fewer than 5 years since incorporation (or 7 in strategic sectors), no dividend distributions since formation, not listed on a regulated market, not created through a merger or split of non-startup companies, and the controlling shareholders must not be individuals or entities with equivalent activities to the startup (to prevent the artificial conversion of existing businesses). A post-incorporation application loses benefits for tax years before certification but activates them from the tax year in which it is granted.
The impatriate regime under Article 93 of the Spanish Personal Income Tax Law (known as the Beckham Law) allows workers relocating to Spain for the first time to pay a flat 24% rate on Spanish-source income up to EUR 600,000, instead of the progressive income tax scale. The Startup Law expands this regime in two ways: first, it extends access to the regime to founding shareholders of empresas emergentes who relocate to Spain (previously only available to employees); and second, it facilitates application of the regime to family members of the holder (spouse and minor children) who relocate with them. For startups seeking to attract international talent or founded by foreigners relocating to Spain, this extension is a significant additional argument for obtaining the certification.
