Autónomo vs SL in Spain is the question every foreign freelancer and small business owner eventually has to answer: stay registered as self-employed, or set up a Sociedad Limitada (SL)? The honest answer is that it depends on how much you earn, how much liability you're willing to carry personally, and — as of 2026 — on a Social Security change that has quietly made the SL route more expensive for many small companies than most people realise.
This guide compares what each structure actually costs in 2026: income tax, Social Security contributions, incorporation costs and ongoing admin, so you can work out which one fits your numbers rather than a generic rule of thumb.
The two structures differ in two fundamental ways, and almost everything else follows from them:
That second point is the one most people underestimate: an SL isn't automatically cheaper just because corporate tax rates look lower than the top IRPF brackets. What matters is the combined tax once the money actually reaches you.
Autónomos pay IRPF on net profit under Spain's progressive scale (state plus regional — Andalucía's combined top rate reaches 47% on income above €300,000):
On top of IRPF, autónomos pay a monthly Social Security contribution (cuota de autónomos) based on your real net income, across 15 brackets. For 2026 the table is frozen at 2025 levels (only the MEI generational-equity component ticks up slightly, to 0.9%), so a self-employed person earning around €2,500/month net pays roughly €427–€869/month depending on the base chosen within that bracket, up to a maximum of €1,606/month at the top end. You can change your contribution base up to six times a year to match your real earnings. The cuota is deductible against your IRPF, which softens the impact somewhat.
An SL pays Impuesto de Sociedades on its profit before anything reaches you personally. For tax periods starting in 2026, the rates are:
That's only half the picture. If you're the administrator and you take a salary, it's taxed under the same IRPF scale as an autónomo — and you'll almost certainly need to register as an "autónomo societario" (a self-employed company administrator), which since January 2026 carries a significantly higher minimum Social Security base: €1,424.40/month, up from around €1,000 in 2025. That pushes the minimum monthly cuota to roughly €448, about €134 more than in 2025, even if your company is barely turning a profit yet. If instead you take money out as dividends, it's taxed separately under the savings scale (19% to 30% depending on the amount) rather than added to your salary income — which is where an SL can genuinely reduce the tax bill for higher earners, but only once you account for both layers of tax together.
Becoming an autónomo is largely a same-day administrative registration (alta) with the Agencia Tributaria and Social Security — no notary, no minimum capital, no company accounts.
An SL requires a minimum share capital of €3,000, fully paid up at incorporation, plus notary and Commercial Registry fees, a company name search, and — usually — a few weeks from start to finish. Since 2022, it's technically possible to incorporate an SL with as little as €1, but the law requires setting aside 20% of annual profits into a legal reserve (double the standard 10%) until the company reaches €3,000 in capital, and the partners remain personally liable for the shortfall if the company winds up before hitting that threshold. Our company formation service handles this end-to-end, including choosing the right structure before you commit to either route.
Ongoing, an SL also means: mandatory double-entry bookkeeping (autónomos can often use a simpler cash-basis system), annual accounts filed at the Commercial Registry, corporate tax returns regardless of profit, and formal administrator duties. That's a real, recurring cost in accountancy fees that a straightforward autónomo setup doesn't carry.
As a rough guide, an SL tends to make financial sense once net profit is consistently well above the point where your marginal IRPF rate (37-45%) clearly exceeds the combined cost of corporate tax plus what you actually withdraw. In practice, that's usually somewhere in the €40,000–€60,000+ net profit range, and more clearly so if you plan to reinvest profit in the business rather than take it all out personally — since undistributed profit is only taxed once, at the corporate rate. Businesses that carry real liability risk (client contracts, staff, physical premises) often incorporate earlier than the tax numbers alone would suggest, purely for the liability protection.
Below that range, or in your first year or two while income is still unpredictable, the numbers usually favour staying autónomo: no incorporation cost, no minimum capital tied up, simpler bookkeeping, and — importantly — you avoid the sharp jump in the 2026 autónomo societario minimum contribution before your company can comfortably absorb it. It's also easier to wind down if things don't work out; closing an SL is slower and more paperwork-heavy than deregistering as autónomo.
When comparing autónomo vs SL in Spain, the most common miscalculation isn't in the corporate tax rate — it's forgetting the second layer of tax entirely. Business owners compare 19-25% corporate tax against 37-47% IRPF and assume the SL wins outright, without factoring in that most of that profit still needs to reach them personally at some point, either as a taxed salary (plus the new, higher autónomo societario cuota) or as taxed dividends. Run both scenarios on your actual expected income before incorporating — not just on the headline rates.
Can I switch from autónomo to an SL later without losing anything?
Yes. Many freelancers start as autónomos and incorporate once income grows past the break-even point. You can also contribute an existing sole-trader business into a newly formed SL, though it's worth getting the structure and timing reviewed first.
Do I still pay autónomo Social Security if I set up an SL?
If you're the administrator and hold a significant stake, yes — you'll typically register as an "autónomo societario," which in 2026 carries a minimum monthly base of €1,424.40, higher than a regular autónomo's minimum.
Is VAT (IVA) different between an autónomo and an SL?
No. VAT obligations (21% general rate, with 10% and 4% reduced rates for specific goods and services) apply the same way regardless of legal structure.
Does an SL actually protect my personal assets?
In principle, yes — liability is limited to the company's assets. In practice, banks often ask company administrators for personal guarantees on loans, and directors can still be personally liable for negligent management or mixing personal and company funds.
Autónomo vs SL in Spain ultimately comes down to your real numbers, not a general rule — and getting it wrong is expensive to unwind later. Our Tax and Accounting Law service can model both scenarios against your actual income and run the numbers before you commit, and our company formation service handles the incorporation itself if an SL turns out to be the right call.
