SL vs Autónomo: When Incorporating Actually Pays Off in Spain 2026

Most Spanish tax advisors put the threshold around €50,000-€75,000 of sustained annual net profit, not a fixed rule, but a general rule of thumb that accounts for both the corporate tax rate advantage and the extra administrative overhead an SL carries. Below that range, the RETA cuota and IRPF an autónomo pays generally comes out ahead once you factor in SL setup and ongoing accounting costs; above it, the SL's flatter corporate tax rate starts to outweigh the added overhead.

An SL pays Impuesto sobre Sociedades: 19% on the first €50,000 of profit and 21% on the rest for microenterprises billing under €1 million a year, under Ley 7/2024. Newly created companies get an even lower 15% rate for their first two profitable years. An autónomo, by contrast, pays progressive IRPF on net income (through the same bands as a salaried employee, our autónomo vs contrato indefinido comparison covers those), which climbs into higher brackets well before an SL's flatter rate would.

Formation itself runs roughly €500-600 in formalities on top of the required share capital (legally as little as €1, though most SLs are formed with around €3,000 to avoid certain legal restrictions), or €1,500-3,500 all-in through some formation services. Ongoing costs are the bigger factor: bookkeeping, annual accounts, and corporate tax filing typically add €1,000-2,000 a year more than operating as an autónomo, with some estimates for fuller accounting/payroll/compliance support running €3,000-8,000 a year.

Yes, structurally. As an autónomo, business net income is your personal income directly. Through an SL, you typically pay yourself a salary (taxed as ordinary employment income, with its own Social Security contributions) and can additionally take dividends from remaining after-tax profit (taxed separately at Spain's savings-income rates), a genuinely different mechanic from an autónomo's single income stream. This split can offer real tax planning flexibility at higher income levels, but it also means the SL's corporate tax rate isn't the only tax you're comparing, personal tax on the salary/dividend extraction matters too.

Yes, this is one of the SL's structural advantages independent of the tax comparison entirely. An SL (sociedad limitada) is a separate legal entity with limited liability, business debts and legal claims generally can't reach the owner's personal assets beyond their capital contribution. An autónomo has no such separation, personal and business liability are legally the same thing, a real risk consideration for anyone in a higher-liability line of work, separate from the pure tax-optimization question.

Yes, and it's the common path in practice. Most freelancers start as autónomo (lower setup cost, faster to begin invoicing, benefits from the tarifa plana discounted cuota in year one) and incorporate an SL once income sustainably clears the €50,000-75,000 threshold and the added administrative overhead becomes worth it. There's no requirement to incorporate from day one, and doing so prematurely, before income justifies the extra €1,000-2,000+/year in overhead, is a common and avoidable mistake.

Both autónomo and SL structures generally have the same IVA obligations for the same type of business activity, VAT registration and filing requirements attach to the business activity itself, not to whether it's structured as a sole trader or a limited company. Incorporating an SL doesn't change your IVA position on its own.
