Employment and self-employment at the same time (pluriactividad, autónomo) in Spain

What pluriactividad means

Pluriactividad means being registered under TWO Social Security schemes at the same time: the Régimen General for your salaried employment and RETA for your self-employed activity.

Sort out my dual-activity case

It is not the same as pluriempleo (two salaried jobs in the same scheme).

You pay contributions under both schemes — having a salaried job does NOT exempt you from paying the self-employed contribution (cuota de autónomo).

Because of the “double” contribution, the law lets you reclaim part of the RETA contributions (devolución por exceso de cotización) if your common-contingency contributions exceed a yearly threshold.

Who this applies to

• People with a salaried job (alta in the Régimen General) who also register as self-employed (autónomo, RETA).
• A common situation for migrants is having a main job alongside self-employed work such as delivery services, freelancing or running a small business.
• Non-EU citizens still need an immigration status that permits self-employment (trabajo por cuenta propia); having a salaried employment contract does not replace this requirement.
• Pluriactividad can affect both your future pension entitlement and your eligibility for a refund of excess contributions.

Your rights: refund and reductions

• Devolución por exceso de cotización: if your common-contingency contributions (General + RETA) exceed the annual threshold set by the LPGE/current budget rules for that year, Social Security refunds 50% of the excess, capped at 50% of your RETA common-contingency contributions — often automatically (de oficio).
• The initial reduced cuota (tarifa plana/cuota reducida) follows the general rules for new autónomos: request it at alta if you qualify, and check separately whether a second reduced year applies.
• Do not mix concepts: the reduced cuota is an upfront benefit; the excess-contribution refund is calculated later if your annual contributions exceed the threshold.
• You already have healthcare through the salaried job; self-employment (autónomo) mainly adds to your pension record.
• The right to challenge an incorrect charge and request an aplazamiento for an outstanding debt.

Deadlines

• Register with RETA before starting your self-employed activity while remaining in salaried employment.
• The exceso de cotización refund: Social Security often processes it automatically; the TGSS must pay it within a maximum of 4 months after the yearly regularisation, except where data is missing or special contribution rules apply.
• The RETA cuota is charged monthly — you pay it regardless of the salaried job.
• Tax returns for your self-employed activity, such as modelo 303 and/or modelo 130 where applicable, are usually filed quarterly.

What to prepare

• Your informe de vida laboral — it shows the alta in both schemes.
• Your contribution bases: the base for your salaried employment, shown on your nómina, and your RETA contribution base.
• NIE and a certificado digital/Cl@ve — for Import@ss.
• For non-EU citizens, proof that your immigration status permits self-employment (trabajo por cuenta propia).

How to set it up

• Your salaried employment remains registered under the Régimen General, with your employer handling the relevant Social Security registration.
• Register as self-employed in the RETA (Import@ss), stating the start of the activity.
• When registering, request the standard cuota reducida if you qualify. Any excess-contribution refund is calculated separately after the annual regularisation.
• After the annual regularisation, check that any exceso de cotización refund due to you has been calculated and paid correctly. It is normally processed automatically (de oficio).
• File the tax forms that apply to your activity (for example 303 and/or 130) on the income from your own activity.

Common mistakes

• Thinking that salaried employment exempts you from the self-employed contribution (cuota de autónomo) — it does not; contributions remain due under both schemes.
• Not checking the exceso de cotización refund after regularisation — an incorrect calculation or missing payment may go unnoticed.
• Confusing the reduced cuota/tarifa plana with the excess-contribution refund — they are different mechanisms.
• Not declaring your self-employed income on the relevant tax returns — it must be declared separately from your salary income.
• Non-EU citizens: starting cuenta propia without a status that grants the right to self-employment.

Debts and disputed charges

• Failure to pay your RETA contribution may result in a surcharge (recargo) and an outstanding Social Security debt; having salaried employment does not remove this obligation.
• If an expected exceso de cotización refund has not been paid, contact TGSS and provide your informe de vida laboral and the relevant contribution-base records.
• If you dispute the amount of the refund or your entitlement to it, gather the supporting documents and submit an explanation. If you have an outstanding debt, you may request an aplazamiento.
• Keep proof of your RETA registration and copies of your nóminas (payslips).
