Spanish SL or autónomo: a decision worksheet for 2026
Compare a Spanish SL with autónomo status using a practical worksheet, 2026 corporate tax examples and the distinction between retained and withdrawn profit.
TL;DR: There is no annual profit threshold that makes a Spanish SL preferable for everyone. Compare personal spending money, business funding and the costs of each structure. The examples calculate corporate tax for an eligible Spanish microenterprise, not your total tax saving.
Key takeaways
- This comparison concerns Spain’s SL and autónomo structures; the language of this page does not change its jurisdiction.
- Not every Spanish SL pays 25% corporate tax in 2026. Eligibility and the tax period matter.
- Retained profit belongs to the company. Distributing a dividend requires a legal distribution check and a separate personal tax calculation.

An SL can be a sensible business structure without reducing your tax bill. It can also add costs without improving your position. Start with two complete budgets: what remains available to you personally and what stays in the business after taxes, social contributions and the costs of each option.
This worksheet concerns Spain’s common tax regime, with sources checked on 17 September 2026. SL means the Spanish Sociedad Limitada; autónomo means an individual carrying on a business in Spain. It does not compare UK limited companies or other countries’ legal forms. Regional foral regimes, territorial incentives, non-resident situations and special regimes require a separate assessment. Use the worksheet to prepare a discussion with your adviser, not as an individual tax return calculation.
To prepare the comparison, use the cash-flow guide to separate receipts and payments, and the Modelo 200 guide to organise the company’s tax documents.
Assemble comparable inputs
Use the same twelve-month period for both options. Keep revenue excluding VAT, accounting profit and cash balance separate. An unpaid invoice can contribute to accounting profit without providing cash.
| Input | What to record |
|---|---|
| Business | Revenue, expenses, depreciation, investment and unpaid customer invoices |
| Personal needs | Monthly net spending, other income, residence and family circumstances |
| Structure | One-off formation costs separately from recurring accounting, insurance and administration |
| Remuneration | The owner’s duties, supportable pay and contributions payable by owner and company, counted once |
| Reinvestment | Planned purchases, hiring and cash reserves, with amounts and dates |
Obtain actual quotes for both structures. Check whether they include payroll, annual accounts and related-party work. Investment is not necessarily an immediately deductible expense; share capital is not an incorporation fee.
Use the applicable tax rules
An autónomo using direct assessment includes business income in the general income-tax calculation. Other income, allowances and the autonomous community can change the result. A marginal rate is not the average rate on the entire profit. See the Spanish Personal Income Tax Law.
For corporate tax periods starting in 2026, the following references are conditional, not rates you may freely choose:
| Situation | 2026 reference |
|---|---|
| General rate | 25% |
| Eligible microenterprise with previous-period net turnover below €1 million | 19% on the first €50,000 of taxable profit; 21% on the remainder |
| Eligible small entity under Article 101, without another applicable rate | 23% |
| Qualifying newly created entity under Article 29.1 | 15% in the first period with a positive tax base and the following period |
The AEAT table and transitional provision 44 set out the transition. Eligibility exclusions, turnover rules and shorter-period adjustments apply. Passive asset-holding entities cannot assume they qualify for these reduced rates.
Incorporating an existing activity does not automatically unlock 15%. Article 29.1 excludes, among other cases, an activity carried on in the preceding year by an individual who will own more than 50% of the new company. The “following period” is not necessarily the next profitable period.
A reproducible example with a defined boundary
Assume an eligible microenterprise with a twelve-month tax period starting in 2026, no special rate, tax credits or loss offsets. Accounting profit equals the tax base after all expenses, including properly assessed owner remuneration and applicable social contributions. These are hypothetical inputs, not a customer case.
For €80,000, corporate tax is 50,000 × 19% + 30,000 × 21% = €15,800, leaving €64,200 after that tax.
| Hypothetical tax base | Corporate tax | Profit after corporate tax |
|---|---|---|
| €50,000 | €9,500 | €40,500 |
| €80,000 | €15,800 | €64,200 |
| €110,000 | €22,100 | €87,900 |
This does not establish a saving over autónomo status: personal taxes and the full costs of both options still need calculating. Accounting profit also does not guarantee available cash.
Retain the result: the €64,200 remains company equity. It is not €64,200 in your personal account or a promise of tax-free withdrawal later.
Propose a €20,000 gross dividend: assuming distributable profits, the required reserves and approvals, and sufficient liquidity, this reduces the retained amount to €44,200. The shareholder must calculate personal income tax on the dividend alongside other savings income. Gross is not net. The AEAT dividend guidance explains the classification.
Pay for work or management is a separate matter. Its classification, documentation and deductibility need checking; relevant related-party transactions must use market value. Do not treat an arbitrary withdrawal as a deductible salary.
Budget for obligations and risk
Limited liability is not an absolute shield. Review personal guarantees, directors’ duties, insurance and contractual limits. A company does not guarantee funding or customer acceptance; ask for the actual requirements.
An SL’s minimum share capital is €1. Below €3,000, additional reserve and liquidation-liability rules apply under Article 4 of the Companies Act. This is separate from formation expenses and operating cash. Allow for bookkeeping, statutory books and annual accounts.
An SL does not automatically eliminate social contributions. Duties and effective control affect the owner’s social-security classification under Article 305. Do not assume a fixed contribution for every director or describe contributions as an income tax.
Leave with two budgets, not a magic threshold
Ask your adviser to show personal net money, company equity and liquidity, contributions, taxes and additional costs separately under each structure. Repeat for lower sales and a reinvestment year; future periods need their own applicable rates. Write down the commercial reason to change and a review date. Needing most profits for living expenses is a different situation from funding expansion or introducing a co-owner.

FAQ
Is there a universal profit threshold for moving to an SL?
No. Compare personal withdrawals, retained profit, taxes, contributions and costs using the same business assumptions.
Does incorporating automatically qualify for 15% tax?
No. Article 29.1 contains conditions and exclusions, including certain previously operated activities. The relief does not necessarily cover two profitable periods.
Does this worksheet calculate my total tax saving?
No. Its numerical example only calculates corporate tax for an eligible microenterprise in Spain in 2026. Personal tax, contributions, costs and liquidity need individual assessment.
