Autónomo vs SL in Spain: Freelancer Guide (2026)

Updated: 8 October 2026

Comparing autónomo vs SL in Spain involves more than comparing tax percentages. Your choice affects who signs contracts, how you receive income, your administrative costs and the responsibilities you assume.

For foreign freelancers, it must also fit the immigration permission under which they work.

This guide explains both structures, the relevant 2026 tax rules and the questions to answer before registering a business or changing an existing one.

What Does Working as Autónomo Mean?

An autónomo operating as a sole trader carries out business or professional activity personally. Contracts and invoices are issued in the individual’s name, and the person assumes the obligations arising from that activity.

This can suit consultants, developers, designers, translators and other independent professionals who want to start without incorporating a company.

There is no minimum share capital for this structure.

An autónomo can hire employees. Having staff does not automatically require an SL, although employer obligations must be fulfilled.

What Is an SL Company?

An SL — Sociedad Limitada — is a Spanish limited liability company with its own legal identity. The company enters contracts, invoices clients and holds its business assets.

An SL can have one shareholder. This is commonly called a Sociedad Limitada Unipersonal, or SLU.

A company can help organise shared ownership, investment and business operations. It also brings corporate formalities and ongoing administration.

For Social Security purposes, these choices can overlap: someone who works in their own SL may still need registration as an autónomo societario.

Autónomo vs SL: Main Differences

The following personal tax discussion assumes ordinary Spanish tax residence. Special incoming-worker regimes, non-resident situations and the Basque or Navarra tax systems require separate assessment.

Can You Set Up an SL with €1?

Spanish company law permits an SL with share capital starting at €1. However, this does not mean the entire business can be established and operated for €1.

While share capital remains below €3,000, additional rules apply:

• At least 20% of profits must go to the legal reserve until that reserve together with share capital reaches €3,000.
• If the company is liquidated with insufficient assets to meet its obligations, shareholders are jointly liable for the difference between €3,000 and the subscribed capital.

You must also budget for incorporation, administration and the resources needed to operate.

Share capital belongs to the company. It is separate from professional fees and registration expenses.

How Are Autónomo and SL Profits Taxed?

Autónomo: Personal Income Tax

Under ordinary IRPF rules, income from the activity contributes to your personal income tax calculation.

For activities using direct estimation, the starting point is generally business income less properly supported deductible expenses, with the applicable adjustments.

IRPF is progressive. Your final liability depends on your overall income, circumstances and the relevant state and regional rules.

A marginal tax rate should therefore not be treated as the percentage payable on every euro of business profit.

SL: Corporate Income Tax in 2026

The general Corporate Income Tax rate is 25%, but qualifying companies can use other rates.

The following table concerns tax periods beginning in 2026 under Spain’s common-territory regime:

The €50,000 band is proportionately reduced for tax periods shorter than a year. Turnover calculations, company groups and exclusions must also be checked.

Taxable profit and turnover are different figures. The turnover threshold determines eligibility; the relevant percentage applies to the taxable base.

The 15% new-company rate is conditional. Moving an existing freelance activity into a newly incorporated SL can fall outside the new-activity requirements.

Company Tax Is Only Part of the Comparison

Money belonging to an SL is not automatically the shareholder’s personal spending money.

Payments to you may take the form of salary, professional remuneration or dividends, depending on the arrangement. Each requires the correct treatment and supporting formalities.

Dividends generally distribute after-tax profits and have personal tax consequences.

A useful comparison therefore considers:

• Company and personal taxes.
• Social Security contributions.
• Accounting and administration.
• How much money you need personally.
• How much the business will retain for investment.

A lower company tax percentage alone does not establish that an SL produces a better overall result.

Will an SL Remove Your Autónomo Contributions?

The Social Security classification must be assessed separately from the company’s tax position.

Someone who regularly works in or manages a company and has effective control may belong in RETA as an autónomo societario. Control can depend on ownership, management functions and relevant family holdings.

Other working shareholders or directors may fall under different classifications.

For ordinary self-employed contributions, the system uses annual net returns and provisional contribution bases, followed by regularisation where applicable. Company-related categories can also have specific minimum-base rules.

Use the current Social Security guide to check your position before estimating monthly costs.

Liability and Ongoing Costs

A sole trader generally assumes business obligations personally. In an SL, shareholders generally do not answer personally for company debts merely because they hold shares.

That protection has limits. Personal guarantees and breaches of directors’ duties can create personal exposure.

Consider the contracts you will sign, the risks of your activity and any appropriate insurance alongside the choice of structure.

An SL also requires corporate bookkeeping, statutory records, annual accounts and relevant tax filings. Obtain a quote covering the services your business actually needs.

Compare the total annual cost of both options, including payroll or licensing where applicable, rather than focusing only on incorporation costs.

How Do You Register Each Structure?

Starting as Autónomo

A practical preparation sequence is:

1. Confirm that you may carry out the intended activity.
2. Identify the activity and relevant tax obligations.
3. Complete the required tax census registration.
4. Arrange Social Security registration where applicable.
5. Prepare invoicing, record keeping and any necessary licences.

The current tax census form is Modelo 036. Modelo 037 was abolished from 3 February 2025.

Tax census registration must be completed before beginning the relevant activity. Where RETA applies, arrange registration by the required start date.

Starting an SL

Prepare the ownership, management, company name, business purpose and capital arrangements.

Incorporation involves a public deed and Commercial Registry registration, together with identification and tax formalities. Assess the Social Security position of everyone who will work in the company.

The government’s CIRCE/PAE system can coordinate many incorporation and startup procedures. Check which additional steps remain necessary for your activity.

Immigration Considerations for Foreign Freelancers

Before deciding who will invoice your clients, check whether your immigration position permits the work you plan to perform.

An NIE, company incorporation or Social Security registration does not itself grant a residence or work authorisation.

Different rules apply to EU citizens and non-EU nationals. Our guide to EU vs. non-EU immigration to Spain explains the relevant frameworks.

Digital Nomad Visa Holders

International teleworking rules distinguish employment from professional activity:

• Employees covered by this route work for companies established outside Spain.
• Professional activity may include work for a Spanish company, provided it does not exceed 20% of the total professional activity.

Consequently, introducing a Spanish SL into your work arrangements needs an immigration review. Having overseas clients alone does not establish that every proposed structure fits the teleworking route.

Check who contracts with whom, what work you personally perform and how the arrangement affects your existing authorisation.

Read our Digital Nomad Visa Spain guide for the route’s requirements.

Special tax regimes for people moving to Spain also have their own eligibility rules. A residence permit and a tax election are separate matters.

Which Structure Should You Choose?

Autónomo can be a practical starting point when you provide services personally, want simpler administration and do not need shareholders.

An SL deserves closer consideration when you want shared ownership, a separate business entity, investment or a structure suited to your contractual risks and operations.

Answer these questions before deciding:

1. What will you earn after expenses? Use a realistic profit forecast alongside turnover.
2. How much will you withdraw? Distinguish personal living costs from money retained by the business.
3. What responsibilities will you assume? Review contracts, guarantees and operational risks.
4. Does it fit your residence permission? Check this before changing how the activity is organised.
5. What will administration cost? Compare both structures using the same assumptions.

These answers are more useful than a universal recommendation based on a single income figure.

Frequently Asked Questions

At What Income Must I Switch to an SL?

There is no universal income threshold requiring every freelancer to incorporate.

An appropriate decision depends on profitability, personal withdrawals, liability, administration and immigration circumstances.

Can I Start as Autónomo and Establish an SL Later?

Yes, but plan the change.

Review how contracts, invoicing, assets, tax registrations and Social Security arrangements will move to the company. Check any immigration implications before implementation.

Do not assume that transferring an existing activity automatically qualifies the company for the 15% tax rate.

Does a Foreign Company Replace Spanish Registration?

A foreign company does not automatically settle the Spanish obligations of someone living and working in Spain.

The assessment depends on the actual work, tax residence, company arrangements and applicable Social Security rules.
