Pluriempleo & Pluriactividad in Spain: Guide for Expats

🇪🇸 Read the original in Spanish

In the dynamic Spanish labour market, it is increasingly common for people to combine different sources of income to achieve financial stability, develop new skills, or start their own business project without giving up the security of a monthly payroll. However, combining several professional activities generates a sea of legal and tax doubts that are crucial to clear up in order to avoid penalties from the Inspección de Trabajo (Labour Inspectorate) or surcharges from the Seguridad Social (Social Security). Concepts such as social security contributions, working hour limits, compatibility of benefits, and tax obligations vary drastically depending on the nature of the activities carried out. In this detailed guide, we thoroughly analyse the difference between pluriempleo (multiple employment) and pluriactividad (multiple activities) under the framework of Spanish legislation so that you can make informed decisions with complete legal certainty.

¿Qué es el pluriempleo y qué es la pluriactividad? Diferencias clave

Although in everyday language they are often used as synonyms, Labour and Social Security Law in Spain clearly distinguish both concepts based on the contribution regimes involved.

El Pluriempleo: Two or more employment contracts

Pluriempleo occurs when a worker provides services for two or more different employers and, therefore, simultaneously within the same Social Security regime. In the vast majority of cases, this regime is the Régimen General de la Seguridad Social (General Social Security Regime for employees, whether full-time, part-time, or permanent-seasonal contracts).

The regulatory framework of reference for pluriempleo is found in the Real Decreto Legislativo 8/2015, de 30 de octubre, por el que se aprueba el texto refundido de la Ley General de la Seguridad Social (LGSS) (General Social Security Act), as well as in the Real Decreto Legislativo 2/2015, de 23 de octubre, por el que se aprueba el texto refundido de la Ley del Estatuto de los Trabajadores (ET) (Workers' Statute).

La Pluriactividad: Simultaneous employment and self-employment

Pluriactividad, on the contrary, occurs when a worker simultaneously carries out activities that require them to contribute to two or more different Social Security regimes. The most common case is that of a professional who works as an employee for a company (contributing to the Régimen General) and, at the same time, carries out an economic activity on their own account as a self-employed person (which obliges them to contribute to the Régimen Especial de Trabajadores Autónomos, RETA - Special Regime for Self-Employed Workers).

El marco legal del pluriempleo: Límites, jornada y cotización

One of the most frequent questions from workers in a situation of pluriempleo is whether there is a limit on the daily or weekly hours they can work across all their jobs.

Límites de jornada en el pluriempleo (Working hour limits)

Article 34 of the Estatuto de los Trabajadores establishes that the maximum duration of the ordinary working day is 40 hours per week on average in annual calculation. However, this 40-hour limit applies to each employment contract individually, not to the worker cumulatively.

This means that, legally, a worker can sign a 40-hour weekly contract with Company A and another 15-hour weekly contract with Company B, totalling 55 hours per week. Nevertheless, the following occupational health and safety limits set out in the Estatuto de los Trabajadores must be scrupulously respected:

• Daily rest: There must be a minimum of 12 hours of rest between the end of one working day and the start of the next (Art. 34.3 ET).
• Weekly rest: A minimum weekly rest of one and a half days uninterrupted (Art. 37.1 ET).

El deber de buena fe y la no concurrencia desleal (Duty of good faith and non-competition)

Although pluriempleo is fully legal and constitutional, Article 21 of the Estatuto de los Trabajadores regulates the non-competition agreement and exclusive dedication. A worker cannot engage in unfair competition against their company. If you work as a software developer for a technology consultancy, you cannot work in the afternoons for another directly competing consultancy, unless you have the express consent of the first one.

If there is a pacto de exclusividad (exclusivity agreement, through which the worker receives express financial compensation), pluriempleo will be totally prohibited with any other company, whether or not it is in the same sector.

La cotización en el pluriempleo y el tope máximo (Contributions and maximum caps)

In a situation of pluriempleo, companies must make social security contributions for the worker in proportion to the hours worked in each of them. The sum of the bases de cotización (contribution bases) of all contracts cannot exceed the maximum contribution cap established annually by the Presupuestos Generales del Estado (State Budget).

For the year 2024, the maximum Social Security contribution cap is set at €4,720.50 per month. If the sum of the contribution bases of your various contracts exceeds this limit, a distribution of caps (known as "distribución de bases de cotización por pluriempleo") must be carried out so that none of the companies over-contribute, prorating the contribution bases proportionally to the salary received in each.

El marco legal de la pluriactividad: Cotización doble y bonificaciones

In pluriactividad, being registered in both the Régimen General and the RETA, the worker faces a double contribution obligation. Fortunately, Spanish legislation provides mechanisms to alleviate this burden and avoid over-contribution.

Bonificaciones en la cuota de autónomos por pluriactividad (Autónomo fee discounts)

To encourage entrepreneurship among those who already have an employment contract, the Social Security offers very attractive reductions on the RETA fee. According to current regulations, if you register for the first time in the RETA while in a situation of pluriactividad, you can opt for the following reductions on the minimum contribution base:

1. If the employment contract is full-time:

• During the first 18 months: 50% reduction of the minimum contribution base.
• During the following 18 months: 25% reduction of the minimum contribution base.

1. If the employment contract is part-time (greater than 50% of an ordinary working day):

• During the first 18 months: 25% reduction of the minimum contribution base.
• During the following 18 months: 15% reduction of the minimum contribution base.

Important note: These discounts are incompatible with the famous Tarifa Plana (Flat Rate) for new self-employed workers. The worker must do the math and choose the option that is economically most advantageous for them.

Devolución de oficio por exceso de cotización en pluriactividad (Automatic refunds for over-contribution)

If you decide not to take advantage of the previous discounts or if your contribution bases are high, it is very likely that the sum of your contributions to the Régimen General (employer and employee contributions) and the RETA will exceed the limit established by law.

For the 2024 financial year, the Ley General de la Seguridad Social establishes that workers in pluriactividad whose contribution amounts for common contingencies (combining Régimen General and RETA) exceed €16,037.80 per year, will have the right to a refund of 50% of the excess over that amount.

The best part of the current regulation is that this refund is made automatically (de oficio) by the Tesorería General de la Seguridad Social (TGSS - Social Security General Treasury) before 1 May of the following financial year, without the worker needing to submit a formal application.

Ejemplos prácticos con cifras reales

To better understand how these mechanisms work, we analyse two common scenarios.

Ejemplo 1: Pluriempleo (Carlos)

Carlos works as a graphic designer for Company A with a 30-hour weekly contract and a contribution base of €1,800. To supplement his income, he accepts a weekend job at Company B for 10 hours per week, with a contribution base of €600.

• Working hours situation: Carlos works 40 hours per week in total. He perfectly complies with the Estatuto de los Trabajadores as he does not exceed the maximum working hours per contract and respects the daily rest periods.
• Contribution situation: Both companies contribute for him. His total accumulated contribution base is €2,400 (€1,800 + €600). Since this sum does not exceed the maximum cap of €4,720.50, no base distribution procedure is necessary.

Ejemplo 2: Pluriactividad (Sofía)

Sofía works full-time as a chemical engineer for a multinational company (Régimen General), with a monthly contribution base of €3,200. In addition, she decides to open an online consultancy on weekends and registers in the RETA. During the year 2024, Sofía contributes to the RETA based on the minimum chosen base, paying a monthly autónomo fee.

• At the end of the year, the sum of the contributions for common contingencies made by her company and herself in the RETA amounts to €18,200.
• As this figure exceeds the legal limit of €16,037.80, Sofía is entitled to a refund for excess contributions.
• Calculation of the refund:
• Excess: €18,200 - €16,037.80 = €2,162.20.
• Amount to be refunded (50% of the excess): €1,081.10.
• The Social Security will automatically deposit €1,081.10 into her bank account during the spring of the following year.

Trámites prácticos paso a paso

If you are going to start a situation of pluriempleo or pluriactividad, these are the administrative steps you must follow:

En caso de Pluriempleo:

1. Communication to the companies: Although it is not always mandatory by collective agreement, it is highly recommended to inform your employers. If the sum of your salaries is going to exceed the contribution cap, you must formally request the distribution of contribution caps from the Tesorería General de la Seguridad Social.
2. Adjustment of IRPF (Income Tax): Go to the human resources department of each company and submit a new Modelo 145 (Communication of data to the payer). Request that they voluntarily increase your IRPF withholding rate. If you do not do this, each company will withhold the minimum corresponding to your individual salary, and when you file your Declaración de la Renta (Tax Return) you will have to pay a high amount due to having multiple payers.

En caso de Pluriactividad:

1. Registration with Hacienda (Tax Agency): Before starting your self-employed activity, you must register in the Census of Entrepreneurs, Professionals and Retainers by submitting Modelo 036 or 037 to the Agencia Tributaria (Tax Agency), selecting the corresponding IAE (Impuesto sobre Actividades Económicas - Tax on Economic Activities) heading.
2. Registration in the RETA: Within a maximum period of 30 calendar days from the start of the activity, you must process your registration in the RETA through the "Importass" portal of the Social Security.
3. Selection of discounts: During the online registration process in the RETA, the system will automatically detect that you are registered in the Régimen General and will give you the option to choose the pluriactividad discount instead of the flat rate, if you meet the requirements.

Errores que debes evitar

• Not adjusting IRPF withholdings: Having two or more payers (whether two companies or a company and yourself as an autónomo) does not mean you will pay more taxes simply for having them, but it does mean that the monthly withholdings will have been too low. If you do not request an increase in the withholding rate on your payslips, next year's Declaración de la Renta will certainly result in an amount "to pay".
• Hiding pluriempleo if an exclusivity agreement exists: Signing an employment contract with a full dedication (exclusivity) clause and carrying out another economic activity in parallel is grounds for fair disciplinary dismissal (despido disciplinario procedente) without the right to severance pay, in accordance with Article 54 of the Estatuto de los Trabajadores.
• Forgetting compatibility limits on benefits: If you are receiving unemployment benefits (paro) or temporary disability benefits (sick leave), you cannot start a second activity without prior notification to the SEPE (State Public Employment Service) or the INSS (National Social Security Institute). Working while on sick leave is a very serious infringement that leads to the loss of the benefit and possible financial penalties.
• Not declaring self-employed income because it is "low": There is a myth that if you invoice less than the SMI (Salario Mínimo Interprofesional - Minimum Wage) it is not necessary to register in the RETA. Although Supreme Court jurisprudence has qualified the "habitual nature" of the activity, the Inspección de Trabajo and the Social Security require registration from the very first euro invoiced. Do not risk your stability to avoid registering.

Preguntas Frecuentes (FAQ)

¿Tengo derecho a dos pensiones de jubilación si estoy en pluriactividad?

Yes, it is perfectly possible to receive two retirement pensions in Spain (one from the Régimen General and another from the RETA). To do this, you must meet the age and contribution years requirements in both regimes independently (a minimum of 15 years contributed in each, of which at least 2 years must fall within the 15 years immediately prior to retirement). If you do not meet the requirements in one of the regimes, the contributions from that one will be accumulated into the other to calculate a single pension.

Si me despiden de uno de mis empleos en pluriempleo, ¿puedo cobrar el paro?

Yes, you can apply for the unemployment benefit corresponding to the job you lost, provided you meet the minimum contribution period required and the termination was not a voluntary resignation. The amount of the paro will be calculated based on the contributions of the lost job, and you can combine the receipt of the benefit with the salary of the job you keep, although the amount of the paro will be reduced proportionally to the working hours of the latter.

¿Qué pasa si me pongo de baja por enfermedad (incapacidad temporal)?

If you are in a situation of pluriempleo or pluriactividad and you suffer a common illness or an accident, the sick leave (incapacidad temporal) affects all your activities simultaneously. A doctor from the Public Health Service will issue a single sick leave note, but you must present copies of this note to each of the companies you work for or carry out the corresponding procedure as an autónomo to receive the subsidy from each of the regimes. It is not permitted to be on sick leave in one activity and continue working in the other.

¿Cómo afecta el pluriempleo a las vacaciones anuales retribuidas?

The right to paid annual leave is guaranteed by Article 38 of the Estatuto de los Trabajadores and is generated independently in each employment contract (a minimum of 30 calendar days per year worked). This means that you will have to negotiate and organize your holiday periods with each company individually. There is no legal obligation for both companies to grant you holidays on exactly the same dates, although this is usually ideal for the rest to be effective.

En resumen

• Pluriempleo involves working for two or more companies within the same regime (Régimen General), while pluriactividad means combining employment with self-employment (Régimen General and RETA).
• There is no maximum hour limit when adding up all your contracts in pluriempleo, but it is mandatory to respect the minimum rest periods of 12 hours daily and one and a half days weekly provided for in the Estatuto de los Trabajadores.
• In pluriactividad, you can benefit from discounts of up to 50% on the autónomo fee during the first 18 months or receive an automatic refund for excess contributions if you exceed €16,037.80 annually in 2024.
• You must closely monitor your IRPF withholdings and update Modelo 145 to avoid unpleasant surprises in your Tax Return due to having multiple payers.
• Transparency with your employers is key to avoid engaging in unfair competition or violating exclusivity agreements signed in your contract.
