Spanish limited company (SL) 2026: costs, advantages and US LLC comparison

3. Setting up a Spanish SL costs 600 to 1,500 euros, requires share capital from 1 euro and brings mandatory commercial bookkeeping. We cover when it pays off, when it does not and why for international digital profiles a US LLC is often a better fit.

Setting up a Spanish limited company (SL) is still the natural step when an autonomo grows and starts to feel the personal regime is too tight. But the SL is not always the best answer: it carries fixed costs, commercial bookkeeping, annual accounts filing and, above all, double taxation when you want to take profits out. Currently there are very serious alternatives, especially the US LLC for 100% international digital profiles. This guide lays out the SL's real costs, its honest advantages, its limits and when to compare it with other structures before deciding.

Real cost of forming an SL

The minimum cost of forming a Spanish SL currently is around 600 euros via an integrated service (notary, mercantile registry, initial advisory, tax and Social Security registration). With traditional notary and external advisory, the cost rises to 1,000-1,500 euros. Share capital: from 1 euro after the Crea y Crece reform, although banks typically require larger actual paid-in capital to open an operating account. Lead time: the express CIRCE route lets you have the SL operating in 24-72 hours; via traditional notary, a week. Reserving the name at the Central Mercantile Registry before any step is advisable.

Recurring costs of maintaining an SL

An SL carries fixed annual costs that a self-employed worker does not: specialised advisory (1,500-3,000 euros per year for full mercantile accounting), filing of accounts at the Mercantile Registry (50-200 euros), fees, extra forms (Form 200, Form 232 for related-party transactions, Form 184 informative in civil partnerships). If the director is a shareholder and works in the company, they must register as a corporate self-employed (monthly quota from 380 euros). All in, the realistic minimum cost of maintaining a small SL approaches 6,000-9,000 euros annually, pre-tax.

Real advantages: protection, taxation and professionalism

The SL brings three measurable advantages. First: it caps liability at the capital contributed, protecting your personal estate in case of bankruptcy or lawsuit (with caveats, because there are veil-piercing scenarios). Second: it pays Corporate Tax at the new reduced rates from Law 7/2024 — microenterprises (turnover < €1,000,000) pay 19% on the first €50,000 and 21% on the rest in 2026; small companies (€1-10M) pay 23%; general rate 25%; vs. 19-47% IRPF; especially useful when your annual base comfortably exceeds 60,000 euros and you reinvest part. Third: the image with large clients, banks, investors and public administrations is clearly superior, with access to contracts some large corporates reserve for companies.

Double taxation: the drawback few mention

The SL's main tax problem is that it pays twice: the company pays 25% on profit and, when that profit is distributed as a dividend to the shareholder, it is reported on personal IRPF as savings income (19-28% by amount). The combined rate can exceed 40-45% of gross profit. There are tools to soften it: director's compensation (deductible for the company and taxed on IRPF), annuities, employer pension plans, retaining profit (without distribution) for reinvestment. The reality is that taking money out of an SL is always more expensive than collecting it as an autonomo.

When the SL really pays off

The SL pays off when several conditions hold simultaneously: stable annual turnover above 80,000-100,000 euros, several shareholders, need to retain profits for reinvestment, exposure to asset risks (rentals, physical products, high professional liability) and clients that prefer to contract with companies. For solo digital autonomos invoicing 50,000-80,000 euros and consuming almost all earnings, it usually does not pay off: tax savings from 25% evaporate when you add recurring costs and double taxation. The tax calculator helps you see it with your own numbers.

SL vs US LLC: when each fits

For 100% digital profiles with mostly non-Spanish clients, a well-managed US LLC usually wins: much lower annual cost (1,500-2,500 euros vs. the SL's 6,000-9,000), 0% federal in the US for non-residents, and taxation only in residence by income attribution, with no double corporate taxation. The SL still wins if your business is physically Spanish, with local clients or the need to hire employees in Spain. The difference between LLC and Corporation also matters depending on your plan.

The legal regime is in Spain's Capital Companies Act and the tax regime in Law 27/2014 on Corporate Tax. If you are considering an SL, compute the total combined cost over three years before forming.

Comparative table SL vs US LLC vs autónomo

Practical cases: when SL vs LLC pays off

Case 1. Digital advisor, 70,000€/year, single US client. Better LLC: 0% federal, IRPF in Spain on net profit. SL loses here due to high fixed costs (6,000-9,000€) and double taxation.

Case 2. Marketing agency 4 partners, 250,000€/year, Barcelona office, 3 employees. Better SL: needs corporate entity for Spanish corporate clients, ability to retain profits at 23% IS, hire payroll with SS contributions, balanced partner distribution. LLC doesn't fit due to operational barrier with local clients.

Case 3. Physical e-commerce Spain, 150,000€/year. Better SL: stock, warehouse, returns, intra-community VAT, courier contracts. LLC complicates physical goods logistics and accounting.

Case 4. Crypto trader, 50-200k€/year, lives between Spain and Andorra. Better LLC for asset protection + residency decision flexibility: with LLC keeps flexibility and, if decides Andorra/Portugal residence, operates LLC from new regime without restructuring.

Hidden SL costs few calculate

For an autónomo invoicing 60,000€/year, the SL switch frequently reduces net income for 2-3 years until billing exceeds 100,000€/year.

Frequently asked questions

Is SL minimum capital really 1€ or still 3,000€? The Business Creation and Growth Act (July 2022) allows SL formation with 1€ minimum capital. BUT during the first years: partners are personally liable up to 3,000€ if the SL doesn't reach 3,000€ in equity. And many banks still require effective 3,000€ capital to open accounts. In practice, contributing 3,000€ remains advisable.

Do I pay double if I take dividends? Yes. The SL pays 23-25% (IS), and when collecting dividends you pay again on personal IRPF savings base (19-28% by bracket). Combined effective: 38-46% by situation. So taking dividends from a small SL is usually inefficient vs autónomo IRPF.

Can I move from autónomo to SL without closing? Yes, but with transition costs: contribution of activity as business branch (non-monetary contribution requiring independent expert report, additional notary fees, goodwill valuation). Typical transition cost: 2,000-4,000€, recovered only if SL lasts years.

Can I have an SL AND an LLC? Yes, structures are compatible. Common pattern: SL for local Spain operation, LLC for US/EU B2B clients. Watch transfers between them: may constitute related-party transactions with documentary obligations (Form 232).

When to close an SL that no longer works? As soon as possible, because an inactive SL still costs ~6,000€/year in maintenance. If 6+ months without activity, calculate closure cost vs keeping it "just in case". Closure takes 6-12 months and ~600-1,500€.

How we close this with the Exentax method

What we see every week in the files that reach us is the same pattern: the question stays as loose ideas, the decision gets postponed and, by the time the tax year closes, people pay more than needed or take on risks that do not pay off. The problem is rarely the rule itself; it is the lack of a written plan with real numbers, owned by someone who understands the case end to end.

What people get wrong

Copying structures seen on social media without modelling their own case against real income, residency and client mix.
Mixing personal money with business cash flow and losing the documentary trail any audit will ask for.
Leaving execution to generic accountants who only file forms, without thinking through the annual strategy or the total cost.

What actually works

Modelling the situation in the Exentax calculator before moving a single piece, to see the total annual cost and not just today's bill.
Separating personal and business flows from day one, with distinct accounts and a living checklist of evidence.
Working with an advisor who sees the pieces together: structure, banking, compliance and residency, not each one in isolation.
Reviewing the whole setup once a year (residency, structure, real activity, banking) instead of waiting for the Tax Inspection to do that review for you with penalties on top.

What if HMRC, the IRS or my local tax authority asks about my LLC?

It's the question every client raises in the first consultation, and the short answer is: your LLC isn't opaque, and a properly declared structure closes any inquiry in standard forms. Your tax authority can request the state Certificate of Formation (Wyoming, Delaware or New Mexico), the EIN issued by the IRS, the signed Operating Agreement, the Mercury or Wise statements for the year, the Form 5472 plus pro-forma 1120 you filed, and the bookkeeping that reconciles income, expenses and movements. If all of that exists and is delivered in order, the inquiry doesn't escalate.

What tax authorities do pursue, and rightly, is sham ownership (nominees, paper residency) and undeclared foreign accounts. A well-structured LLC is the opposite: you appear as beneficial owner in the BOI Report when applicable (verifiable at fincen.gov/boi), you sign the bank accounts and you declare the income where you actually live. The structure is registered with the state Secretary of State, with the IRS and, when European banks are involved, inside the CRS perimeter of the OECD standard.

The mistake that really sinks an inquiry isn't having an LLC; it's not attributing the income correctly in your domestic return, not declaring foreign accounts when the year-end balance exceeds the local threshold (€50,000 in Spain via Modelo 720; the equivalent FBAR / Form 8938 in the US for residents; T1135 in Canada), and not documenting related-party transactions between the member and the LLC. Those three fronts are worth closing before any request arrives, not after.

## What an LLC does NOT do

- It does not exempt you from tax in your country of residence. If you live in Spain, France, Germany or Portugal, you are taxed there on worldwide income. The LLC organises your US side (zero federal tax for non-resident SMLLC pass-through, absent Effectively Connected Income); it does not switch off your domestic taxation. The income tax is computed on the attributed profit, not on the dividends actually paid.

- It is not an offshore vehicle or a BEPS scheme. It is a US entity recognised by the IRS, registered in a specific state with physical address, registered agent and annual informational filings. Classic offshore jurisdictions (BVI, Belize, Seychelles) leave no public trace; an LLC leaves a trace in five different places.

- It does not protect you if you commingle funds. The pierce the corporate veil doctrine kicks in as soon as a judge sees the LLC and the member behaving as the same wallet: mixed accounts, personal expenses paid from the LLC, no signed Operating Agreement, no bookkeeping. Three suspicious transactions are enough.

- It does not save you social security contributions at home. If you are self-employed in Spain, France or Germany, your monthly social contribution remains identical. The LLC handles the trading side with international clients; your personal contribution is independent.

- It does not exempt you from declaring foreign accounts. Spain residents file Modelo 720 / 721; UK residents, the SA106; Portugal residents, the Anexo J of Modelo 3 IRS; Germany residents, the Anlage AUS. Those obligations belong to the individual, not to the LLC.

At Exentax we cover those five fronts every year alongside the US federal calendar (Form 5472, pro-forma 1120, FBAR, state Annual Report and BOI Report when applicable). The goal is that no inquiry finds a loose end and that the structure withstands a 5-to-7-year retroactive review.

How the real cost of an SL stacks up over the first three years

A defensible cost view of an SL needs to look beyond the day-one notary fee. In year one, the freelancer absorbs the formation cost (notary, registry, initial capital), the bookkeeping and corporate-tax preparation work, the autónomo societario contribution if the freelancer is also a director, the periodic VAT and corporate tax filings, and the legal-deposit obligations. In year two, the formation cost disappears but the recurring obligations stabilise; the corporate tax filing introduces its own complexity in profit allocation, dividend planning and reserves. In year three, an SL with sufficient profit and structured dividends produces a clear separation between operational profit and personal income, which is a real advantage for project planning, but the combined cost of the corporate-tax layer plus the personal IRPF on dividends usually exceeds what an autónomo would pay below a clear breakeven of net activity. We typically estimate that breakeven on real annual net basis only around well-established mid-six-figure income with stable Spanish billing; below that threshold, the SL is more comfortable for the institutional posture than efficient on the tax bill.

Three operational comparisons we walk clients through

The first comparison is invoice receipt: an SL issues invoices in its own corporate name and receives funds in a corporate Spanish bank account, which is comfortable for Spanish public-sector clients and for some institutional buyers; an autónomo invoices in personal name into a personal account; a US LLC invoices in its own name into a Mercury, Wise, Stripe or Relay account, which is comfortable for international clients and not always recognised by Spanish public-sector buyers. The second comparison is profit extraction: SL profits move to the owner via salary (subject to IRPF in the general base plus social contributions) or dividends (subject to IRPF in the savings base, after corporate tax already paid); autónomo profit equals personal income directly; LLC profit flows to the owner pass-through into IRPF in the corresponding category. The third comparison is reporting load: SL carries a corporate tax return, accounting deposit and quarterly VAT; autónomo carries quarterly VAT and Form 130 plus annual IRPF; LLC carries Form 5472, bookkeeping, annual state filings and the integration with the owner's IRPF. Each structure is heavier than the lighter ones; the question is which weight matches the activity, not which is "best".

Three operating habits that make an SL light or heavy

The first habit is the use of a dedicated business bank account from day one. An SL with a clean operating account (in our practice, a Spanish corporate account works for local Spanish operations; for international flows, the Mercury, Wise, Stripe and Relay names recur) avoids the most common bookkeeping confusion: a personal expense paid from the corporate account that the bookkeeper has to reclassify and that the auditor will eventually flag. The second habit is the monthly closing rhythm. An SL closed once a month (revenue posted, expenses posted, bank reconciled, payroll closed) is light to maintain because each closing is small; an SL closed once a year is heavy to maintain because the year-end becomes a multi-week reconstruction. The third habit is the dividend planning. An SL with a clear annual dividend policy (when, how much, in what proportion to retained earnings) makes the IRPF and the corporate tax interaction predictable; an SL where dividends are decided on the spot at year-end produces last-minute IRPF surprises for the owner. None of the three habits requires advanced expertise; all three require discipline and a thirty-minute monthly review.

A documentation kit per closed quarter that pre-empts AEAT requests

For an SL, the documentation kit per closed quarter that we keep on file mirrors the one for an autónomo but with corporate flavour. First: the issued-invoice ledger with client name, NIF, date, amount and VAT detail. Second: the supplier-invoice ledger with the same fields. Third: the bank statement reconciled against the two ledgers, with any unmatched line documented in a one-line note. Fourth: the quarterly Form 303 (VAT) and Form 111 (withholdings if applicable) receipts. Fifth: the payroll for the quarter if the SL has employees, including the autónomo societario contribution if the director is also a member. Sixth: any contract or order for non-routine operations of the quarter. Seventh: a one-page closing memo summarising the quarter. The kit is small, predictable and largely automatic if the closing rhythm is monthly; it is the difference between an AEAT request answered in two days and one that opens a wider review.

A second-year reset that protects the SL from drifting

The second year of an SL is the moment to perform a quiet reset on the operating habits established in year one. We typically run this reset in January of the second calendar year, with three checks. First check: the chart of accounts is reviewed to ensure that the categories actually used during year one are clean (no orphan accounts, no duplicates), and that any new recurring expense category is added before posting the first January transaction. Second check: the bank-account reconciliation procedure is documented in a one-page note (which account, which frequency, which person, which sign-off), so that the year-two closings do not depend on the year-one improvisation. Third check: the dividend policy for year two is decided in writing in January, not in November when the corporate tax is being prepared, so that the IRPF on dividends is anticipated by the owner and not landed as a year-end surprise. The three checks take an hour and they are the difference between an SL that runs lighter every year and one that accumulates a backlog that the third year will not absorb.

How a Spanish SL and a US LLC can coexist for the same owner

In a small subset of our practice, the answer is neither SL nor LLC alone but both, with a clear allocation between them. The owner runs the Spanish-billed activity through the SL (which provides the Spanish corporate envelope, the local invoice and the local banking) and the international-billed activity through the LLC (which provides the cross-border envelope, the international invoice and the Mercury, Wise, Stripe or Relay banking). The two structures are operated separately, with two separate bookkeepings, two separate annual reports and two separate flows back to the owner's IRPF declaration. The setup is heavier than a single structure and only justifies its weight when the activity profile genuinely splits between two distinct client bases; for an owner whose activity is purely domestic or purely international, the single-structure answer remains the simpler one.

A practical note on the corporate-bank account choice from day one

The corporate bank account chosen on day one shapes most of the SL's operational comfort during the first three years. For SL with predominantly Spanish flows (Spanish clients, Spanish suppliers, Spanish payroll), a Spanish corporate bank works smoothly: domestic transfers are fast, the integration with the Spanish payment infrastructure is native, and the bank statement format is familiar to the local bookkeeper. For SL with predominantly international flows, the picture changes; the names that recur in our setups for international flows are Mercury, Wise, Stripe and Relay, with the choice depending on the specific currency mix, the payment-acceptance needs and the integration with the bookkeeping system. The clean answer is rarely a single account; it is more often a primary corporate Spanish account for local operations, paired with a secondary international account for cross-border flows, with both reflected in the same monthly closing.
