Buying property through a company in Spain: when an SL pays off

If you've been in the world of property investment in Spain for a while, you've probably heard that "you have to buy through an SL" (sociedad limitada, a Spanish limited company). Online courses say it, finance YouTubers say it, and so do some advisers with an interest in selling company formations. The reality is more nuanced. The limited company is a useful tool for certain investor profiles at certain points in their career. For others, it only adds cost, complexity and obligations with no real tax benefit.

This article neither sells the SL nor rules it out. It analyses when it makes real sense and when it's an unnecessary cost that does more harm than good.

How the individual investor is taxed versus the company

To understand whether an SL pays off, you have to compare the tax burden of the two alternatives with concrete numbers. An investor who is a persona física (an individual, as opposed to a company) pays tax on income from property (rents) under IRPF (Spanish personal income tax) on a progressive scale. In 2026, the state scale ranges from 9.5% on the first €12,450 of taxable base up to 24.5% above €300,000, and each autonomous region's own scale is added to it.

In addition, if rental income exceeds certain thresholds or the taxpayer has other high income, the effective rate can be between 30% and 45%-47% for the highest incomes.

The SL pays the Impuesto sobre Sociedades (IS, Spanish corporation tax), which in 2026 has a general rate of 25%. Newly created companies that carry on an economic activity are taxed at 15% for their first two years with a positive taxable base; that rate doesn't apply to sociedades patrimoniales (property-holding companies), such as one that only lets flats without a full-time employee. This creates a tax differential that is the central argument in favour of the SL.

But there's a catch that many analyses ignore: the money the SL earns stays inside the company. If the investor wants to take it out for personal use, it has to be distributed as a dividend (with 19% withholding on the band up to €6,000, and higher scales for larger amounts) or as a salary (social security contributions plus IRPF). The real tax differential has to be calculated taking into account the full tax cycle: IS at 25% + IRPF on the dividend at 19-30% = a real effective rate of 40-48%, in many cases similar to or higher than that of an individual taxpayer in the high IRPF brackets.

When the SL does have a real tax advantage

The SL's real advantage shows up in specific situations, where it isn't a crude comparison of headline rates but the mechanics of the tax that create concrete opportunities:

• The investor who reinvests everything: If the profits aren't taken out of the company but reinvested in buying more assets, the money "saved" by not being taxed at high personal rates works faster. The SL acts as a vehicle for accumulating capital at the IS rate (25%) without immediate tax dilution. For the investor who builds wealth without needing to extract personal income, this is the most genuine advantage.
• The investor with high employment income: If the investor has a salary that already uses up the top IRPF brackets, adding rental income as an individual would tax it directly at the highest marginal rate. In the SL, that same income is taxed at 25% (or at 15% if the company is newly created and isn't a holding company). The net differential in that case can be 15-20 percentage points on the rental income.
• The investor who flips: For individuals, gains from selling property are taxed as capital gains at 19-30% depending on the amount. In the SL, those gains form part of the IS taxable base and are taxed at 25%. Where the gain is high, the effective rate can be similar, but the SL lets you offset those gains against losses from other years and deductible expenses more flexibly.
• The investor with several properties and several expenses: The SL lets you deduct expenses that for an individual are only partly deductible or are subject to limits: depreciation of the properties, repair and maintenance costs, mortgage interest, office supplies, a vehicle with justified professional use. The deductibility of expenses under IS is generally broader than under IRPF for the property investor.

When the SL doesn't pay off or actually makes things worse

This is what nobody tells you on the "set up your property holding SL" courses:

• The investor with a single flat: The SL has fixed costs that at a minimum include an annual gestoría (the agency that handles the paperwork and accounts, €1,500-3,000), corporation tax, annual accounts at the Registro Mercantil (the Companies Registry), formation costs (€600-1,200) and greater complexity in banking transactions. For a single flat let at €800/month, these fixed costs completely erode any nominal tax advantage there might be.
• The investor who needs to take out the income to live on: If you take out 100% of the profits as salary or dividends, the total tax burden (IS + distribution) is usually similar to or higher than paying tax directly as an individual. The SL only saves tax in net terms if there's money that stays inside the company.
• The investor who wants mortgage finance: Banks are more demanding when lending to companies than to individuals. They require more documentation, usually ask for a bigger deposit (60-70% LTV, loan-to-value, on company deals) and mortgage rates for an SL are usually between 0.5 and 1.5 points higher than for an individual. If you need a mortgage to buy, the SL can make you pay more for the financing than you save in tax.
• Assets contributed to the SL are taxed: If you already own properties as an individual and want to transfer them to an SL, that transfer is treated as a sale and generates a capital gain subject to IRPF. It isn't free. Many investors find this out late and at the worst possible moment.

The holding company versus the active trading company

There's a relevant concept that many advisers don't explain clearly enough: a company whose main purpose is managing its own property portfolio (with no additional commercial activity) can be considered a "sociedad patrimonial" (holding company) for tax purposes, and some IS advantages don't apply to it in the same way as to a real economic activity.

On the other hand, if the company carries on a letting activity with the necessary resources (the law requires at least one person employed full time to manage the lettings), it is considered an economic activity and qualifies for better tax treatment, including the application of specific deductions and potentially the régimen de entidades dedicadas al arrendamiento de viviendas (ERE, the special tax regime for companies that let homes), which offers a 40% rebate on the IS tax due on income from letting main residences.

The regime for home-letting entities (ERE)

This regime is relatively unknown outside professional circles, but it's very powerful for the investor with a significant stock of homes. The 40% rebate on the IS tax due on rental income means the effective rate on that income falls to 15% (25% × 60%). The requirements:

• The company's main activity must be letting homes located in Spain.
• It must have at least 8 homes let at the same time (this number can be reached gradually).
• The homes must have been kept let for at least 3 years.

For the investor who has, or aspires to have, 8 or more properties let, this regime can radically change the tax equation and make the SL by far the best option.

When to make the leap: practical signs

There's no magic number, but there are signs that it's worth seriously considering an SL:

• You have 3 or more properties let, or expect to have them in the next 2-3 years.
• Your employment income already puts you in the 40-45% IRPF bracket and you don't need the rental income for everyday personal spending.
• You systematically reinvest your rental profits to buy more assets and don't plan to take the money out for at least 5-7 years.
• Your goal is to build a property portfolio of 8 or more homes to which you want to apply the ERE regime.
• Your volume of activity justifies hiring someone, or working on it part time yourself as the company's director, which allows the SL to have a real economic activity rather than simply being a holding company.

If none of these signs applies to you, holding property as an individual is probably your best investment vehicle. At least until the volume justifies the change.
