The Zona Especial Canaria (ZEC) offers the lowest Corporate Income Tax rate of any fully EU-compliant regime in the European Union: **4%** on the taxable base generated in the Canary Islands. The registration window closes on **31 December 2026**, with no possibility of extension. After that date, companies that are not already registered will have permanently missed the opportunity — and the complete process from first enquiry to effective registration takes between four and six months.
This guide analyses in detail what the ZEC is, who can join, how the reduced rate works, what the employment obligations are, the stages of the registration process, and why the ZEC outperforms other European regimes in terms of effective tax advantage.
Legal Framework: Law 19/1994 and European State Aid
The ZEC was created by Law 19/1994 of 6 July, on the modification of the Economic and Tax Regime of the Canary Islands (REF). Its European legal basis rests on Article 349 of the Treaty on the Functioning of the European Union (TFEU), which recognises the special status of outermost regions and allows the EU to authorise differentiated aid regimes to compensate for their structural disadvantages.
The European Commission originally authorised the ZEC regime through Decision C(2000)1840 as State aid compatible with the internal market. Successive renewals have maintained continuous legal coverage. The current authorisation covers the registration of new entities until 31 December 2026 and the activity of already-registered entities until 31 December 2027.
The key implementing regulation is Royal Decree 12/2006 of 13 January, approving the Regulations of the ZEC Consortium. This text governs the managing body, the application procedure, annual verification requirements, and the grounds for removal from the register. The substantive Corporate Income Tax rules for ZEC entities are set out in Articles 28 to 50 of Law 19/1994, as amended by successive Budget Laws and now integrated into Law 27/2014 on Corporate Income Tax.
The 4% Rate: How It Works in Practice
The 4% reduced rate does not replace the standard IS rate on the entity’s entire taxable base. It operates on a special ZEC taxable base (ZEC-TB) that must be calculated separately and is subject to several caps:
The ZEC Special Taxable Base
The ZEC-TB covers only income from operations physically carried out in the Canary Islands with clients not themselves registered in the ZEC. Excluded from the ZEC-TB are:
- Revenue generated outside the islands (sales to mainland clients through genuine mainland operations)
- Transactions between ZEC-registered entities (which are taxed at the standard rate)
- Financial income not inherent to the authorised activity
A ZEC entity must maintain analytical accounting that allows it to segment its activity and demonstrate what percentage of its income falls within the ZEC scope. This is one of the highest-risk areas in AEAT inspections of ZEC entities.
Quantitative Caps by Employment Level (Article 43 of Law 19/1994)
The maximum amount of ZEC-TB subject to the 4% rate depends on the number of employees maintained in the Canary Islands:
| Employees in Canary Islands | Maximum base taxed at 4% |
|---|---|
| 5 – 8 | €1,800,000 |
| 9 – 11 | €2,500,000 |
| 12 – 14 | €3,100,000 |
| 15 – 17 | €3,600,000 |
| 18 – 20 | €4,200,000 |
| 21 – 24 | €4,900,000 |
| 25 – 29 | €5,400,000 |
| 30+ | €5,400,000 + €485,000 per additional employee |
The ZEC-TB exceeding the cap is taxed at the standard 25% rate (or at 15% for new companies in their first two profitable years). All other income of the entity outside the ZEC-TB is also taxed at the general rate.
Tax Saving: A Worked Example
A software company headquartered in Las Palmas, with 7 employees and €2 million of annual profit attributable to ZEC activity:
- With ZEC: €1,800,000 × 4% = €72,000 + €200,000 × 25% = €50,000 → total tax: €122,000
- Without ZEC (standard rate): €2,000,000 × 25% = total tax: €500,000
- Annual saving: €378,000
Compatibility with Other REF Incentives
The ZEC does not operate in isolation. The Canary Islands Economic and Tax Regime offers a set of stackable incentives that significantly increase the total advantage:
Canary Islands Investment Reserve (RIC). Allows deducting up to 90% of undistributed profits earmarked for investments in the archipelago within a four-year window. The ZEC + RIC combination can reduce the base subject to the 4% rate to near zero for companies with high reinvestment capacity.
Canary Islands Investment Deduction. Investments in new fixed assets generate a Corporate Income Tax deduction of up to 25% (versus the standard 10%), capped at 50% of the adjusted gross tax liability. This deduction is compatible with the 4% rate.
IGIC. The Canary Islands General Indirect Tax — the local equivalent of VAT, with a standard rate of 7% — does not apply to exports or intra-EU transactions. ZEC entities that invoice primarily to clients outside the Canary Islands benefit from a substantially lighter indirect tax environment.
Las Palmas Free Zone. Companies engaged in warehousing and distribution activities can combine the ZEC tax benefits with the free zone customs regime, deferring or exempting import duties on goods destined for re-export.
Eligible Activities: What Can Register?
Law 19/1994 sets out a closed list of authorised activities for the ZEC. The main eligible categories are:
- Manufacturing industry (excluding activities serving the local Canary Islands consumer market)
- Technology and IT: software development, applications, cybersecurity, cloud services, telecommunications
- Research, Development and Innovation (R&D&I)
- Business services: consulting, engineering, financial advisory, legal services
- Digital content and advertising
- International trade and logistics: distribution and warehousing for export
- Maritime transport and auxiliary port activities
- Environmental activities linked to waste management or renewable energy
Excluded from the regime:
- Regulated financial activities (banking, insurance, investment funds)
- Real estate and residential construction for local sale
- Retail to the final Canary Islands consumer
- Energy production and distribution for the domestic Canary Islands market
For borderline cases, the ZEC Consortium issues non-binding preliminary opinions on eligibility before the formal application.
Registration Requirements: The Actual Standard
1. Registered Office and Effective Management in the Canary Islands
The entity must have its tax and registered domicile within the ZEC geographic scope (the Canary Islands archipelago) and the effective management and control of the business must be exercised from the islands. The AEAT is particularly vigilant about substantive compliance with this requirement: it is not sufficient to register a company in Las Palmas if actual management operates from Madrid or Barcelona.
In practice, this requires at least one director with executive functions to reside in the Canary Islands, and the governance bodies to hold their ordinary meetings in the archipelago. When a ZEC subsidiary of a mainland parent is created, the formal management independence between the two entities must be genuine and documentable.
2. Minimum Employment: 5 on Major Islands, 3 on Minor Islands
The employment minimum is the most closely scrutinised requirement in registration and ongoing monitoring proceedings. The exact conditions are:
- At least 5 employees if the entity is based in Gran Canaria or Tenerife
- At least 3 employees for Lanzarote, Fuerteventura, La Palma, La Gomera or El Hierro
- Contracts must be employment (labour) contracts, full-time
- Employees must reside and work physically in the Canary Islands, not remotely from the mainland
- The minimum must be reached within the first year of activity and maintained throughout the regime
A resident director can count as one of the required employees if there is a formal employment relationship and they meet the residence and dedication requirements.
3. Minimum Fixed Asset Investment in the Canary Islands
- €100,000 in fixed assets located in the Canary Islands for entities on Gran Canaria or Tenerife
- €50,000 for entities on the minor islands
This investment can take the form of equipment, installations, office furniture, computer hardware, or real estate. Purely financial assets and mere capital contributions without corresponding tangible assets located in the archipelago are not accepted.
4. Real Economic Activity: Substance Requirement
Article 44 of Law 19/1994 requires that the operations generating the ZEC-TB be carried out physically in the Canary Islands. This implies a genuine economic substance requirement: the entity must have its own human and material resources to carry out the activity on the islands, and cannot simply invoice from a Canarian letterbox operations that are actually conducted elsewhere.
The AEAT has significantly intensified controls on this requirement in recent years, particularly for digital services companies that attempt to domicile in the Canary Islands without effectively transferring part of their production or service delivery team to the islands.
The Registration Process: Phases and Real Timelines
Registration with the ZEC Official Entity Register involves a formal procedure before two separate bodies — the ZEC Consortium and the AEAT — with a total timeline of four to six months under normal conditions.
Phase 1: Prior Report from the ZEC Consortium (4–8 weeks)
A descriptive memorandum is submitted to the ZEC Consortium (Las Palmas de Gran Canaria) containing:
- Detailed description of the planned activity and products or services to be commercialised
- Business plan with three-year financial projections
- Fixed asset investment plan in the Canary Islands
- Employment plan: number of positions, profiles, hiring timeline
- Corporate documentation (articles of incorporation or adaptation, tax ID)
- Identification of directors and evidence of their Canary Islands residence
The Consortium issues a mandatory opinion on the activity’s eligibility. This opinion does not bind the AEAT, but is a prerequisite for the formal application. The timeline is four to eight weeks, though it can extend during periods of high demand (typically the second half of the deadline year).
Phase 2: Incorporation or Adaptation of the Company (2–6 weeks)
For new companies, a Spanish SA or SL must be incorporated with a Canary Islands registered address before a Canarian notary. For an existing mainland company, the options are:
- Incorporating a Canarian subsidiary (newly formed SL, 100% owned): the cleanest option in terms of asset separation and economic substance
- Transferring the registered office of the existing company to the Canary Islands: viable but requires a shareholders’ resolution and rigorous substance compliance from day one
- Converting a Canary Islands branch or permanent establishment into an independent entity: less common and more fiscally complex
In all cases involving a group, it is essential to document intra-group relationships and verify that transfer prices comply with the arm’s length principle (Art. 18 Corporate Income Tax Law), as the rate differential between a ZEC entity (4%) and a mainland parent (25%) creates profit-shifting incentives that the AEAT will monitor closely.
Phase 3: Formal Application to AEAT Canary Islands Office (up to 3 months)
The registration application is submitted to the Special Delegation of the AEAT in the Canary Islands accompanied by:
- ZEC Consortium report
- Incorporation or adaptation deed
- Employee residence certificates (or signed employment contracts)
- Documentary evidence of fixed asset investment (made or committed)
- Evidence of directors’ actual residence in the Canary Islands
The AEAT has three months to resolve. Administrative silence has a rejection effect, requiring an administrative appeal if the deadline passes without an express decision.
Phase 4: Start of Activity and Operational Registration
Once registration is granted, the entity must:
- Start its activity in the year following registration
- Meet the employment and investment requirements before the end of the first operating year
- Notify the AEAT of any material change (change of activity, reduction in employment, asset disposal)
Failure to meet the employment or investment requirements in the first year results in automatic removal from the register and regularisation of the Corporate Income Tax applied at the reduced rate.
International Comparison: ZEC vs. Madeira vs. Ireland vs. Malta
The ZEC does not operate in a competitive vacuum. Several European regimes compete to attract international investment with reduced corporate tax rates. This is the updated 2026 comparison:
| Parameter | ZEC (Spain) | Madeira (Portugal) | Ireland | Malta |
|---|---|---|---|---|
| Effective CIT rate | 4% | 5% | 12.5% | ~5% (via 6/7 refund) |
| Geographic base | Canary Islands operations | Madeira/Azores operations | Full CIT | Full CIT |
| Minimum employment | 5 (major islands) / 3 (minor) | 1–5 (variable) | None (general) | None formally |
| Minimum investment | €100,000 / €50,000 | €75,000 | None | None |
| Cap on reduced-rate base | Yes (scales with employment) | Yes (€2.73M per employee) | No | No |
| Pillar Two impact | Affected if group >€750M revenue | Affected | No (already ≥15%) | Affected |
| Tax treaty network | 100+ (Spanish network) | ~80 (Portuguese network) | 75+ | ~75 |
| EU blacklist risk | Low (notified regime) | Low | Low | Low |
| EU Commission scrutiny | Moderate | Moderate | High (OECD disputes) | Increasing |
ZEC competitive advantages over the alternatives:
The ZEC has the lowest effective rate (4%) of any regime in EU territory when the taxable base does not exceed the per-employee caps. Unlike Malta, it introduces no operational complexity or offshore structures. Unlike Ireland, the tax advantage is far greater for mid-size companies. Spain’s tax treaty network is broader than Portugal’s, simplifying dividend repatriation and the elimination of withholding taxes at source.
Limitation for large multinational groups:
Groups with consolidated revenues above €750 million are subject to the Pillar Two Global Minimum Tax (Law 7/2024, in force from 2024), which imposes a 15% global minimum effective rate. For these groups, the gap between the ZEC’s 4% and Pillar Two’s 15% floor is collected at the parent company level. The cost-benefit analysis remains favourable in most cases — the ZEC generates savings on the Spanish source tax that are only partially offset by the Pillar Two top-up — but requires group-specific modelling.
For companies below the Pillar Two threshold — the vast majority of SMEs and mid-size international businesses — the ZEC retains its full advantage.
BMC’s Advantage: Las Palmas Base
BMC has a tax and corporate team with an operational base in Las Palmas de Gran Canaria, which enables us to guide clients through the entire ZEC registration process with the local knowledge that this type of operation requires:
- Managing the relationship with the ZEC Consortium and preparing the descriptive memorandum
- Incorporating the ZEC entity before a notary in Gran Canaria
- Filing with the AEAT Canary Islands and tracking the application through to resolution
- Designing the transfer pricing structure between the ZEC entity and group companies
- Annual tax compliance to meet the ongoing employment, investment and substance requirements
- Modelling the combined tax saving from ZEC + RIC + investment deductions
The December 2026 deadline leaves limited time. The full process takes between four and six months; companies that wait until the second half of 2026 face a real risk of not completing the procedure in time.
