Self-employed vs limited company in Spain
Choosing between autónomo and Sociedad Limitada (SL) is not simply a question of which pays less tax. It changes who signs contracts, who owns the business assets, how risk is contained, how profit reaches you and how much administration the business carries.
For a solo, low-risk activity that needs to start quickly, self-employment may be proportionate. An SL becomes more attractive when the project has partners, meaningful contractual risk, employees, retained profit or a plan to bring in investment.
The difference in one table
| Criterion | Self-employed (autónomo) | Limited company (SL) |
|---|---|---|
| Legal person | The individual carries on the activity | The company is a separate legal person |
| General liability position | Business obligations are generally personal | Shareholders generally do not answer personally for company debts merely as shareholders |
| Owners | One individual | One or more individual or legal-person shareholders |
| Formation | Census and Social Security registrations; no company incorporation | Name, capital, deed, NIF and Mercantile Registry registration |
| Direct tax | The individual's business income enters personal taxation | The company is subject to Corporation Tax; money paid to owners has its own tax treatment |
| Accounting and corporate work | Usually lighter, depending on activity and tax regime | Commercial accounting, corporate books, annual accounts and company decisions |
| Bringing in investors | No share capital to divide | Ownership represented by company participations |
| Closing or changing | Usually simpler to cease the individual activity | Formal company dissolution, liquidation or transfer may be required |
“Limited liability” is not absolute. A director can incur liability for breach of duty, a founder can give a personal guarantee, and special rules apply to capital, taxes, Social Security and wrongful conduct. The legal form reduces a category of risk; it does not make the people involved immune.
When self-employment tends to fit
Registering as autónomo may be a practical starting point when:
- you are the only owner and operator;
- initial investment and contractual exposure are modest;
- customers are buying your own professional work;
- you do not need to issue shares or retain significant profit in a separate entity;
- keeping launch and administration simple is important.
The self-employed person must register the activity with the Spanish Tax Agency before starting. Since 3 February 2025 the simplified Form 037 has been abolished; census registrations use Form 036, with assisted services available for individuals. A person who habitually carries on an economic activity on their own account and falls within the applicable rules must also register with Social Security before starting.
Model the contribution separately with the self-employed contribution calculator. A contribution estimate is not the same as the final income-tax cost.
When an SL tends to fit
An SL may be a better foundation when:
- two or more people will own the project;
- ownership percentages, voting and transfers need to be documented;
- the business signs leases, financing, supply or employment contracts with meaningful exposure;
- profits may stay in the company to fund operations;
- investors, grants or counterparties expect a company;
- the business needs continuity beyond one individual's activity.
An SL can have a single shareholder. Spanish law allows capital from €1, but until capital plus legal reserve reaches €3,000, special reserve and liquidation-liability rules apply. The legal minimum should not be confused with a sensible operating budget.

Tax: why the headline rate is not enough
An autónomo is a natural person. Net income from the activity is determined under the applicable personal-income-tax rules, and the person's full circumstances affect the result.
An SL is normally a Corporation Tax taxpayer. But company profit is not automatically the founder's spendable personal income. Salary or professional remuneration, director remuneration and dividends each have their own conditions and tax treatment. Social Security may also apply to a working shareholder or director depending on control and duties.
The correct comparison therefore asks:
- How much profit will the activity produce after deductible expenses?
- How much cash must the founder take out personally?
- Will profit remain in the business for investment?
- What remuneration is commercially and legally appropriate?
- Where is each person tax-resident?
- Which Social Security regime applies to the actual work and control relationship?
Do not choose an SL only because one Corporation Tax percentage looks lower than a marginal personal-income-tax rate. Compare the company and owner together.
Administration and recurring cost
The self-employed route normally involves invoices, tax returns, record books and Social Security obligations. The exact list depends on the activity, VAT position, customers, employees and tax regime.
An SL adds company-level obligations: commercial accounting, legalisation of books, annual accounts, shareholder and director decisions, Corporation Tax, beneficial-ownership information and electronic dealings with authorities. Professional accounting support is therefore a recurring cost, not only a formation expense.
The complete SL formation guide explains the setup process. Use the SL formation timeline to compare that process with a direct self-employed registration.
Foreign founders: add the immigration question
Neither legal form overrides immigration rules. An EU national can work as self-employed in Spain under EU free-movement rules, subject to Spanish residence and registration formalities. A non-EU national who will carry out the activity in Spain needs an immigration status that permits that work.
A non-resident can own shares in an SL without moving to Spain, but ownership alone does not grant residence or work rights. Start with Starting a business in Spain as a foreigner if the founder, shareholder or director lives abroad.
A decision checklist
Choose the structure only after writing down:
- expected revenue, costs and cash needed personally;
- the value of assets and contracts exposed to business risk;
- current and future owners;
- whether shares or external investment will be needed;
- employment and Social Security position;
- the value of limited liability after guarantees are considered;
- monthly accounting and compliance capacity;
- immigration and tax residence of each founder;
- the likely exit: cease an individual activity, sell shares or wind up a company.
Use the self-employed vs SL vs SA comparison to turn these facts into a structured comparison rather than relying on a generic turnover threshold.
