Rep Office vs Branch vs Subsidiary in Spain 2026: Key Differences
Compare Representative Office, Branch (Sucursal), and Subsidiary (S.L.) in Spain. Liability, tax, costs, and how to choose the right structure in 2026.
Key Facts at a Glance
| Structure | Legal Personality | Can Invoice/Sell? | Parent Liability | Best For |
|---|---|---|---|---|
| Rep Office | No | No | Full (mitigated by inactivity) | Market exploration |
| Branch (Sucursal) | No | Yes | Unlimited | Multinationals with centralized control |
| Subsidiary (S.L.) | Yes | Yes | Limited to contributed capital | SMEs and growing businesses |
Preliminary Clarification
**"Branch" and "Sucursal" are exactly the same thing.** "Branch" is the English word for the Spanish "Sucursal." The legal framework, tax obligations, and risk level are identical.
Option 1: Representative Office (Oficina de Representacion)
The lightest corporate structure a foreign company can establish in Spain. No independent legal personality and no governing body.
Fundamental Limitation
A Rep Office **cannot engage in any economic or commercial activity**:
- Cannot sell goods
- Cannot invoice for services rendered to Spanish clients
- Cannot execute commercial contracts on behalf of the company
Permitted Activities
Limited exclusively to auxiliary or preparatory functions:
- Market research
- Information gathering
- Coordination activities
- Marketing campaigns
- Preliminary assessments ahead of investment
Tax Treatment
| Aspect | Detail |
|---|---|
| Corporate Income Tax | Generally not subject (no revenue in Spain) |
| Commercial Registry | Not required to register |
| Tax ID (NIF) | Must obtain one (begins with letter "N") |
| Employees in Spain | Full employment and Social Security obligations apply |
| Tax filings if employees | Form 111 (quarterly) and Form 190 (annually) for income tax withholdings |
Risk: Reclassification
If activities exceed auxiliary functions and resemble core business activity, the Spanish Tax Agency may reclassify the structure as a **permanent establishment**, triggering full tax obligations (Corporate Income Tax, VAT, all associated filings), potentially with penalties and back-assessments for prior undeclared fiscal years.
Option 2: Branch (Sucursal) — Operating Without Incorporating
A permanent establishment of your foreign company on Spanish soil. Has managerial autonomy and a permanent representative, but **no independent legal personality**. It is the same foreign entity operating directly in Spain.
Key Difference from Rep Office
A Branch is **fully authorized to engage in commercial activity**: sell products, issue invoices, execute commercial contracts, operate without restriction.
Critical Issue: Unlimited Liability
Because a Branch is not a separate legal entity, **there is no limitation of liability**. If the Branch incurs debt, faces a lawsuit, or encounters any legal contingency, the parent company abroad is **liable with the entirety of its assets**. The risk passes through directly with no corporate shield.
Tax and Regulatory Obligations
| Aspect | Detail |
|---|---|
| Accounting | Must maintain its own set of accounts |
| Annual statements | Must file with Commercial Registry |
| Taxation | Taxed on profits generated in Spain; regime depends on applicable DTT |
| Registration | Must register with Commercial Registry via public deed (notary) |
| Documentation | All parent company documents must be apostilled and officially translated |
Option 3: Subsidiary (S.L.) — Recommended
Creating a new Spanish company, typically a **Sociedad Limitada (S.L.)** (limited liability company), in which the shareholder is your foreign company.
Principal Advantage: Asset Protection
A Subsidiary has **independent legal personality** — a distinct legal entity entirely separate from the parent company. It functions as a corporate firewall:
- If the subsidiary becomes insolvent, faces litigation, or accumulates liabilities, exposure is limited to share capital contributed in Spain
- Parent company remains protected (absent fraud or court-ordered piercing of corporate veil)
Additional Advantages
| Advantage | Detail |
|---|---|
| Banking | Spanish banks place considerably greater trust in an S.L.; easier account opening and financing |
| Commercial credibility | Local suppliers/clients perceive S.L. as more reliable; stronger position for public procurement |
| Operational autonomy | May define own corporate purpose (even different from parent), maintain own governance, make decisions independently |
Tax Treatment
| Tax | Rate/Detail |
|---|---|
| Corporate Income Tax | 25% standard rate |
| New entities (first 2 years with positive income) | 15% |
| VAT | Standard rates apply |
| Withholding taxes | Applicable |
| Parent company taxation | Only on dividends received; may benefit from DTTs and EU Parent-Subsidiary Directive |

How to Choose
Choose a Rep Office if:
- Only intend to explore the Spanish market without selling or invoicing
- Need minimal presence for feasibility studies, coordination, or marketing ahead of investment
- Lightest and most cost-effective option, but most restrictive
Choose a Branch if:
- Large multinational requiring fully centralized control from foreign headquarters
- Prepared to expose entire parent company net worth to Spanish operational risks
- Warranted under very specific tax circumstances or when corporate structure demands it
- NOT appropriate for majority of companies
Choose a Subsidiary (S.L.) if:
- SME, growing enterprise, or any business wanting to operate while safeguarding assets
- Full operational capacity with limited liability needed
- Superior banking access and commercial credibility required
- Clear, predictable tax framework desired
- **Recommended structure in the vast majority of cases**
