Setting Up a Spanish SL Company to Buy Property: Is It Worth It?

What Is a Spanish SL?

An SL (Sociedad Limitada) is the Spanish equivalent of a UK limited company. It is the most common corporate structure in Spain, used by businesses of all sizes. The "Limitada" refers to limited liability — the shareholders' personal assets are protected from the company's debts, just as with a UK Ltd.

Some UK property investors choose to purchase Spanish property through an SL rather than in their personal names. The idea is to take advantage of corporate tax rates, deductible expenses, and inheritance benefits. But whether it is genuinely beneficial depends entirely on your individual circumstances.

Key Features of an SL

• Minimum share capital: €3,000 (must be fully paid up at incorporation)
• Shareholders: One or more (can be individuals or other companies). A single-shareholder SL is called an SLU (Sociedad Limitada Unipersonal).
• Director (Administrador): At least one director, who can also be a shareholder. Directors have personal liability for tax debts and certain other obligations.
• Corporate tax rate: 25% on profits (15% for the first two years for new companies with qualifying activity). Since 2023, small companies with turnover under €1 million pay a reduced rate of 23%.
• Annual accounts: Must be filed with the Registro Mercantil (Companies Registry) annually
• Audit: Not required unless the company exceeds certain size thresholds (total assets over €2.85 million, turnover over €5.7 million, or more than 50 employees)

Setup Costs

Incorporating a Spanish SL involves the following costs:

• Notary fees: €400-€800 for the deed of incorporation (escritura de constitución)
• Companies Registry fee: €100-€200 for registration with the Registro Mercantil
• Company name reservation: €15-€20 from the Registro Mercantil Central
• Legal/advisory fees: €1,500-€3,000 for a lawyer to draft the articles of association, handle the incorporation, and set up the company
• Minimum share capital: €3,000 (deposited in a Spanish bank account)
• Digital certificate: €20-€50 for the company's electronic certificate
• CIF registration: Free (the CIF is the company's tax identification number, obtained from the Agencia Tributaria)

Total setup cost: approximately €3,000-€5,000 all-in, plus the €3,000 share capital.

Annual Running Costs

A Spanish SL has ongoing costs that a personal property owner does not:

• Accountant (asesoría contable): A company must keep proper accounting records and file quarterly VAT returns (if applicable), quarterly corporate tax instalments, and annual corporate tax returns. A typical accountant charges €150-€300 per month (€1,800-€3,600 per year) for a small property-holding SL.
• Annual accounts filing: The accountant will prepare the annual accounts (balance sheet, profit and loss, notes) and file them with the Registro Mercantil. This is usually included in the monthly fee.
• Corporate tax return (Modelo 200): Filed annually, usually included in accountancy fees.
• Companies Registry annual fee: Not applicable in Spain (unlike the UK's Companies House fee).
• Bank charges: Spanish banks charge corporate accounts more than personal accounts. Expect €100-€200 per year in bank fees.
• Legal compliance: Annual shareholders' meeting minutes, updated beneficial ownership registers, and other formalities. Your accountant or lawyer handles these for €200-€500 per year.

Total annual running cost: approximately €2,500-€4,500 per year, before considering property-related costs. This is the overhead you pay simply for having the company structure, regardless of whether the property makes any income.

Tax Advantages for Rental Properties

The main tax advantage of holding rental property in an SL is the ability to deduct a wider range of expenses and to benefit from the lower corporate tax rate on retained profits.

Corporate Tax Rate vs Personal Income Tax

An SL pays corporate tax at 25% (or 23% for small companies) on its net rental profits. Compare this to personal tax rates:

• Non-resident personal rate: 24% on gross income (no deductions for non-EU residents) or 19% on net income (for EU/EEA residents)
• Spanish resident personal rate: up to 47% on higher income bands

For a Spanish tax resident with significant rental income, the corporate rate of 25% is substantially lower than the personal rate of 37-47% that would apply to higher income bands.

Deductible Expenses in an SL

An SL can deduct all expenses genuinely incurred in generating rental income:

• Mortgage interest: Fully deductible against rental income
• Depreciation: 3% of the construction value per year (excluding land value). On a property worth €300,000 with a land value of €100,000, that's €200,000 × 3% = €6,000 per year in tax-free depreciation
• Repairs and maintenance: All costs of maintaining the property
• IBI (council tax): Fully deductible
• Community fees: Fully deductible
• Insurance: Fully deductible
• Management fees: Property management, key holding, cleaning
• Professional fees: Accountant, lawyer, gestoría
• Travel expenses: Reasonable travel costs for property inspections (limited and subject to scrutiny)
• Furniture and equipment: Depreciated over their useful life

Retaining Profits vs Distributing Dividends

An important consideration is what happens when you take money out of the company. While profits retained in the company are taxed at 25%, when you distribute dividends to yourself as a shareholder, those dividends are taxed again — as personal savings income at 19%-28% if you are a Spanish resident, or subject to withholding tax if you are a non-resident.

This creates double taxation: 25% corporate tax plus 19-28% dividend tax. The combined effective rate can reach 40-46%, which may be higher than the personal rate you would have paid without the company.

The SL only provides a genuine tax saving if you retain profits within the company (for reinvestment in more property, for example) rather than distributing them. If you need the rental income for personal living expenses, the company structure may not save you tax at all.

Inheritance and Succession Benefits

This is where the SL structure can offer significant advantages, particularly for UK families concerned about Spanish inheritance tax.

The Problem with Personal Ownership

When a person dies owning Spanish property, the property is subject to Spanish inheritance tax (Impuesto sobre Sucesiones y Donaciones). The rates, allowances, and reductions vary by autonomous community, but for non-residents or residents of regions with less generous allowances, the tax bill can be substantial.

How an SL Helps

If the property is owned by an SL, and you hold shares in the SL rather than the property directly, what passes on death is the shares, not the property. This has several potential advantages:

• Shares vs property: In some cases, inheriting shares in a company may attract different (sometimes lower) tax treatment than inheriting property directly, depending on the jurisdiction of the heir and the structure of the company.
• Business property relief: If the SL qualifies as a business (empresa familiar) under Spanish law, heirs may benefit from a 95% reduction in the value of the shares for inheritance tax purposes. However, qualifying for this relief requires the company to be actively managed and not merely a passive holding company.
• Avoiding forced heirship: Shares in a company can be structured with different classes of rights (voting, dividend), potentially giving more flexibility in succession planning than direct property ownership.
• Avoiding probate in Spain: If the SL is incorporated in another jurisdiction (such as the UK or Gibraltar), the shares may not need to go through Spanish probate. However, this introduces additional complexity and may not survive scrutiny by Spanish tax authorities.

Warning: The Spanish tax authority (Hacienda) is very aware of companies set up purely to avoid inheritance tax. If the SL's only asset is a property used by the shareholders, and it has no genuine business activity, the tax authority may look through the company (levantamiento del velo — "lifting the veil") and treat the property as if it were owned personally. The company must have genuine substance to withstand scrutiny.

When It Makes Sense

An SL for property ownership typically makes financial sense when:

• Multiple investment properties: You own (or plan to own) two or more rental properties in Spain, generating significant rental income. The corporate structure allows efficient reinvestment of profits and deduction of all business expenses.
• High rental income: If your combined rental income exceeds €60,000-€80,000 per year, the 25% corporate rate saves significant tax compared to the personal rate of 37-47% on higher bands.
• Active property business: You are running a genuine rental business — managing multiple properties, reinvesting profits, growing a portfolio. This also strengthens the case for business property relief on inheritance.
• Complex inheritance planning: You have specific succession planning needs that benefit from the flexibility of a corporate structure.
• Privacy: While Spanish property registries are public, company ownership provides a degree of privacy (although beneficial ownership registers are now mandatory).

When It Doesn't Make Sense

An SL is generally not worthwhile when:

• Single holiday home: If you buy one property for personal use with occasional rental, the annual running costs of €2,500-€4,500 will outweigh any tax benefit.
• Low rental income: If your rental income is below €30,000 per year, the accountancy costs eat into any tax saving.
• Personal use property: If the property is primarily for your own use, you cannot deduct the running costs against rental income (because there is little or no rental income). The company still has the overhead costs, but no tax benefit.
• Needing to extract cash: If you need the rental income for personal expenses, the double taxation on dividends eliminates the corporate rate advantage.
• Short-term ownership: If you plan to sell within 5 years, the setup costs and annual running costs are hard to recover. Capital gains tax within the SL (25%) plus dividend tax on distributing the proceeds makes the overall tax burden higher than personal ownership.

The Bottom Line: Run the Numbers

The decision to use an SL should be based on a detailed financial analysis, not general advice. Have your asesor fiscal (tax adviser) prepare a side-by-side comparison showing total tax and costs over 10 years under both personal and corporate ownership scenarios, based on your specific numbers.

As a rough guide: if your annual rental profit (after all expenses) exceeds €40,000 and you plan to retain profits for reinvestment, the SL will likely save you money. Below that threshold, the running costs and complexity usually outweigh the benefits.

Whatever you decide, ensure you get advice from both a Spanish tax adviser and a UK tax adviser, because the interaction between Spanish corporate law, UK tax law, and the DTA creates additional considerations that a single-country adviser may miss.
