The comunidad de bienes: setting it up, taxes and when to choose an SL

The comunidad de bienes is regulated in articles 392 and following of the Código Civil (the Spanish Civil Code): it exists when the ownership of a thing or a right belongs jointly to several people. Applied to business, it is a contract between 2 or more partners who pool assets, money or work to operate an activity, setting the percentage of each one.

It does not have its own legal personality: the partners are the ones who act and are liable. It also does not require a minimum capital, a notarial deed (unless real estate is contributed) or registration in the Registro Mercantil (the Commercial Registry). That is why it is the lightest startup formula for 2 or 3 people.

It fits particularly well for shared rentals, inheritances with real estate that are operated jointly, professional offices and small low risk businesses. If the activity involves significant debts, employees or strong investment, it is advisable to consider an SL from the beginning, as explained below.

The core of the process is the private setup contract: it identifies the partners, describes the contributions of each one (money, assets or work), sets the participation quotas, the name (usually the chosen name followed by "CB"), the address, the activity and the rules for administration, distribution and exit. A well drafted contract avoids most future conflicts between partners.

A notario (a Spanish notary public) is only needed if real estate is contributed: in that case article 1280.1 of the Código Civil requires a public deed and the contribution is registered in the Registro de la Propiedad (the Land Registry), which extends the process by several weeks. Managora prepares the contract, coordinates that notarial step when applicable and submits everything else.

Setting up a CB with business activity is subject to the corporate operations modality of the ITP and AJD tax, but exempt (article 45.I.B.11 of the consolidated text of the tax): form 600 is submitted to the tax agency of your autonomous community without paying any fee.

With the signed contract, the entity's NIF (tax identification number) is requested from the AEAT using form 036, signed by all partners. The CB is assigned a NIF starting with the letter E and the census registration of the activity is communicated on the same form. Since February 2025 form 037 no longer exists: everything is processed with form 036.

The CB does not pay Corporate Tax: it is taxed under the income attribution regime (articles 86 to 90 of the Ley del IRPF). The profit is calculated at the entity level and attributed to each partner according to their percentage; each one integrates it into their own personal income tax return (or into their Corporate Tax if the partner is a company).

The Directorate General for Taxes has confirmed in multiple binding rulings (among others, V2271-16, V4433-16 and V4149-16) that the comunidad de bienes remains under income attribution even if its activity is commercial: only civil partnerships with legal personality and commercial purpose started paying Corporate Tax (article 7 of Ley 27/2014).

For VAT the situation is reversed: the taxable person is the community itself, which submits the quarterly form 303 with its NIF. In addition, the CB submits form 184 every January, the annual informative return that communicates to Hacienda (the Spanish tax authority) how much is attributed to each partner (mandatory if it carries out economic activity or if its income exceeds €3,000 per year).

Each partner, for their part, advances the personal income tax of their percentage quarterly through form 130 for instalment payments. With a turnover of less than €1,000,000, the entity is exempt from paying the IAE tax, although the activity must be registered in the census.

Yes, every partner who works regularly, personally and directly in the activity must register as an autónomo (freelancer) in the RETA system. Registration is requested in Importass, the portal of the Seguridad Social (the Spanish social security system), before starting the activity (it can be requested up to 60 calendar days in advance). A partner who only contributes capital and does not work in the business has no obligation to pay contributions.

Since 2023, freelancers pay contributions based on real income: a base is chosen according to the expected monthly net income within the current general and reduced tables, and the Seguridad Social regularises it later with the real data provided by Hacienda. The exact fee depends on the bracket: you can calculate it in the official Importass simulator.

Anyone registering for the first time in the RETA can request the reduced start of activity fee (the so called flat rate) of €80 per month during the first 12 months, extendable for another 12 if the income remains below the minimum wage. Managora manages the registration of the entity and guides you on the registration of each partner.

It is the great downside of the CB. As the entity does not have legal personality, the partners are liable for the business debts with all their personal assets, present and future (article 1911 of the Código Civil). A default to suppliers, a penalty or a compensation can end up affecting the home or savings of each partner.

Against Hacienda the risk is even more direct: article 42.1.b) of the Ley General Tributaria declares the participants of these entities jointly and severally liable for their material tax obligations, in proportion to their participation.

That is why the CB is ideal for activities with low and controllable economic risk. If the business is going to take on debt, hire staff or sign high value contracts, the limitation of liability of an SL is worth what it costs to set it up.

There are 4 clear signs: high and sustained profits (the marginal personal income tax rate of the partners comfortably exceeds the Corporate Tax rate), growing risk that makes it advisable to separate personal and business assets, need for bank or investor financing, and entry or exit of partners, which in an SL is articulated with shares and in a CB requires tweaking the contract.

The barrier to entry to the SL is minimal today: since Ley 18/2022 it can be set up with €1 of capital, with the safeguard of allocating at least 20% of the profit to the legal reserve until capital and reserve reach €3,000. For financial years starting in 2026, an SL that invoices less than €1,000,000 is taxed at 19% for the first €50,000 of the tax base and at 21% for the rest, compared to the progressive personal income tax scale borne by the partner.

The transition from CB to SL does not force you to liquidate the business: the contribution of the activity to a newly created company can benefit from the tax neutrality regime of the Corporate Tax when there are valid economic reasons (limiting liability, professionalising management, preparing succession), as the Directorate General for Taxes has repeatedly admitted in binding rulings. Managora studies your case and can take care of both the comunidad de bienes today and the SL when the time comes.
