Spanish SL Architecture
From the Choice of Vehicle to the First Annual Close
Spanish SL Architecture is a 492-page decision file for founders who are considering a Spanish limited company (sociedad limitada). It explains what limited liability does and does not protect, where an SL beats sole trading (the autónomo) and why the answer depends on how much profit leaves the company, and how a company that holds assets rather than trades can destroy wealth-tax and succession reliefs (the patrimonial trap, article 5.2 LIS). It covers constitution (name, capital, object, statutes, notary, registry, bank and beneficial-ownership register), the corporate tax rates, salary versus dividend, the founder's social-security classification, VAT and invoicing, books and accounts, related parties, the foreign-asset returns including the crypto return (Modelo 721), trusts, holdings and anti-abuse rules, exit, succession, and the running company (first employee, funding, foreign clients, tax inspections). Appendices provide a six-gate constitution sheet, an annotated statutes model, minutes, an asset register, a comparator, a calendar and letters, all in Spanish drafting models whose professional review is pending. Law is read as of 13 November 2026 and every claim carries an A, B or C grade. It is educational material, not legal, tax or investment advice.

Why this manual exists
“An SL saves tax once you earn more than sixty thousand.” “Put the property in a company; the rate is lower.” “A Spanish company makes it simpler.” Each sentence is repeated daily by agents, forums and some advisers. Each leaves out the variable that decides the answer, and the founder finds out which one at the first annual return, the first wealth-tax filing or the first death in the family, long after the deed that cannot be cheaply undone.
Spanish SL Architecture is a 492-page decision file for the founder who has not yet signed. It starts before the choice of vehicle, with what limited liability does and does not protect, and ends after the first annual close. Its method is gates, not opinions: every answer carries a document and a date, and the six-gate constitution sheet in Appendix A turns the whole manual into a deed you can hold against a later adviser who proposes something else.
What it settles
- Whether the SL is the right vehicle. The shield is real and narrow. Three exposures reach the founder personally, each a decision rather than an accident, and a regulated profession or a foreign operator may need a different vehicle altogether.
- Whether the company beats sole trading for you. Not a rate against a rate, but two layers against one, decided by how much profit leaves each year. The manual shows the two errors that make the standard comparison useless, and gives you a comparator for your own numbers.
- What the wrapper destroys. For the property owner, the family and the investor, the classification as trading or patrimonial decides more than the rate. Chapter 3 is the one that most often reverses the decision.
- What the deed fixes. Name, capital, object and the statutes’ remuneration, transmission and exclusion clauses, drafted once and amended at cost, then the execution sequence through notary, registry, bank and the beneficial-ownership register.
- What you really pay. Four corporate rates and the reserve that reduces the base first, the order in which profit may leave, and the founder’s own contribution classification, including the 2026 change to the minimum base for a controlling shareholder that last year’s models miss.
- What crosses the border. Why a Spanish company does not make a non-resident Spanish, the foreign-asset returns and the crypto return, trusts and foundations, and the VAT, withholding and residence questions of selling to foreign clients.
- How the running company behaves. VAT and invoicing, books and annual accounts, related parties, the first employee, funding by capital or loan, tax inspections, and four ways to exit with what survives each.
Rates and thresholds as formulas
Every rate, threshold and deadline is printed with the norm behind it, the date it was read and a status, so a founder whose filing falls after the edition date recomputes from the source in force rather than from a number printed here. Chapter 21 is the register and the watch that keeps it current.
Dated and graded
Spanish company and tax rules sit on several statutes and administrative practice that moves. So every legal or numerical claim carries an evidence grade: A for a primary source, B for a corroborated secondary source, C for a working reading. Where the edition could not close a claim at the primary source, a gap callout says what to read to close it, and Appendix K logs what Revision 2 verified and corrected. Law is read as of 13 November 2026.
Tools you can use on Monday
Appendix A is the six-gate constitution sheet. Appendix B is an annotated model of the statutes, with a note on each article about what it decides later and what you lose if it is drafted the other way. Appendix C compares the vehicles on one grid. Appendices D and E give you corporate minutes and an asset register with the accounts pack. Appendix F is the SL-or-autónomo comparator, Appendix G a foreign-assets worksheet, Appendix H the fiscal calendar, Appendix I requests and compliance packs, and Appendix L the first twelve months with the signing-day pack.
An honest note on the instruments
The statutes, minutes, letters and packs in Appendices B to J are drafting models in Spanish, and at this edition their review by an abogado colegiado and a gestor is pending. Each carries a notice saying so, and the manual states that the edition is priced accordingly. They are for you to read before the notary and for your lawyer to adapt. They are not documents to sign.
Built for founders who move capital
If your wealth is in digital or other assets, the structure you choose before the deed matters more than the rate you are quoted after it. This manual keeps the order right: decide the vehicle, test the classification, fix the statutes, then compute the tax. It is the corporate layer of the series, and it takes the outputs of the residence and special-regime analyses (the Post-Golden Visa Playbook and the Beckham Law Codex) as inputs without making you pay twice for the same explanation.
What it will not do
It will not recommend a notary, gestor, lawyer, bank or formation agent. It forecasts no reform. It does not reproduce the consolidated statutes, does not sign a deed or file a return, and does not replace a Spanish corporate lawyer and a tax adviser. It improves the questions you ask and the evidence you hold when you ask them.
Inside the manual
- 1
What the SL Does and Does Not Do
Limited liability, its exceptions and the vehicles that are not this one: the three ways the shield reaches the founder personally.
- 2
SL or Autónomo: The Crossover
Two tax layers against one, and the payout policy that decides between them. Why "an SL saves tax above a certain profit" is not a computation.
- 3
The Patrimonial Trap
Article 5.2 LIS and the exemptions a holding company can destroy: wealth tax, succession relief and the rates the household was counting on.
- 4
Identity, Name, Capital, Object
Four inputs fixed at the deed and expensive to change afterwards.
- 5
The Statutes That Decide Later
Remuneration, transmission and exclusion clauses, drafted once and amended at cost.
- 6
Notary, Registry, Bank, UBO, Powers
The execution sequence, and the two clocks the founder does not control.
Show the other 22 chapters
- 7
The Rate You Actually Pay
Four corporate rates, two thresholds and the capitalisation reserve that reduces the base before any rate applies.
- 8
Salary or Dividend
One channel deductible and one not, the order in which profit may leave, and the withholding that is a prepayment, not an extra charge.
- 9
Owner Pay and Social Security
The classification that follows the shareholding, not the payroll, and the 2026 minimum-base change that most models still miss.
- 10
VAT and the Invoicing Clock
Two invoicing regimes, four dates, and one announcement that is not law.
- 11
Books, Accounts, Asset Register
Four clocks, one register, and the deposit nobody calendars.
- 12
Related Parties and the Calendar
The founder on both sides of the transaction, and who owns each deadline.
- 13
Information Is Not Taxation
Three layers, two taxpayers, and the article that decides who reports: why a Spanish company does not make a non-resident founder Spanish.
- 14
Modelo 720 and 721
Three categories of foreign assets, one crypto return and an ecosystem in transition, with the custody test and where the reporting directive stands.
- 15
Trusts, Foundations and UBO
No trust category, four asset categories, and the duty that follows ownership.
- 16
The Holding Layer and Anti-abuse
What the dividend exemption does, what it does not do, and the economic motive that must exist before you insert a holding.
- 17
The Trading Founder
Freelance, commerce and software: three activities, three decisive questions.
- 18
The Asset Holder
Property, the family holding and the non-resident: three cases, one classification.
- 19
The Adviser File
Two competences, the seam between them, and the questions that test both the lawyer and the gestor.
- 20
Exit, Capital Operations, Liquidation
Four ways out, what each costs and what survives the company, including personal guarantees and administrator exposure.
- 21
The Register and the Watch
Formula, value, norm, date and status for every parameter, and the cycle that keeps them current.
- 22
Wills, Succession and the Estate
Which law governs the estate, and who pays tax on it.
- 23
Leaving, Switching and Failing Safely
The exit file: re-routing, deregistration and what survives.
- 24
The First Employee
Payroll, contracts and the cost that arrives with the first hire, which is not the gross salary.
- 25
Funding the Company
Capital, shareholder loans and the instruments that sit between them, plus the young-company incentives the start-up law created.
- 26
The Foreign Client and the Remote Operator
VAT on cross-border services, withholding abroad and the question of whether another state also claims the company as resident.
- 27
The Inspection File
How to respond to a tax request, the clocks that run, and what the response costs or saves.
- 28
Appendices A to L
A six-gate constitution sheet, an annotated statutes model, a vehicle grid, minutes, an asset register, the SL-or-autónomo comparator, a foreign-assets worksheet, a fiscal calendar, requests and compliance packs, a glossary, the verification log and the first twelve months.
Is it for you?
Built for
- Founders and freelancers considering a Spanish SL who have been told that a company "saves tax" and want the computation before they sign the deed
- Investors and families thinking of putting property, a portfolio or a family participation inside a Spanish company and who must first test what the wrapper destroys
- Non-resident founders who own or will own a Spanish company while living elsewhere, and need to separate where the company is resident, where they are resident and which filing follows
- Remote operators selling services to foreign clients from a Spanish company: VAT, withholding and corporate residence
- Lawyers, gestores and family offices who want one ordered file of questions, thresholds and stop-signs for Spanish company clients
Not for
- Anyone looking for which notary, gestor, bank or formation agent to hire: the manual recommends none of them
- Founders whose open question is the residence route or the special regime election: the Post-Golden Visa Playbook and the Beckham Law Codex cover those, and this volume uses their outputs as inputs
- Readers who want signed, ready-to-file instruments: the Spanish statutes, minutes and letters are orientative drafting models for your lawyer to adapt, and their professional review is pending
- Regulated professions, institutional fundraising and large group structures: the manual flags where another vehicle may be required, and does not design them
- Readers who want a forecast of the next tax reform or an election outcome: the manual monitors change, it does not predict it
- Anyone expecting the manual to replace a Spanish corporate lawyer and a tax adviser
