Employee job and self-employment at the same time (pluriactividad, autónomo) in Spain
Have a salaried job and want to run something on the side? That is dual salaried work and self-employment (pluriactividad) — contributing to two Social Security schemes at once: the Régimen General (through your employer) and the RETA (as self-employed, autónomo). It is legal, but you still pay the self-employed contribution (cuota de autónomo). The upside: because you double-contribute, you may reclaim part of the cuota (devolución por exceso de cotización). The initial reduced cuota (tarifa plana/cuota reducida) follows the general new-autónomo rules, not a separate pluriactividad reduction. Below: how it works, what is cheaper, how to claim the refund and which taxes apply.
What dual activity is
Dual activity is working in TWO Social Security schemes at once: the Régimen General (salaried, contributions paid by your employer) and the RETA (self-employed, you pay the cuota).

It is not the same as pluriempleo (two salaried jobs in the same scheme).
You contribute in both schemes — having a salaried job does NOT exempt you from 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 migrant case: a main job plus a side activity on your own (delivery, freelancing, a small business).
- Non-EU nationals: registering as self-employed (autónomo) still needs a status with the right to cuenta propia — a salaried contract does not replace it.
- Combining affects your pension calculation and a possible refund of 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 a wrong charge and request an aplazamiento on a debt.
Deadlines
- Alta in the RETA — before you start the self-employed activity (the salaried job runs in parallel).
- 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.
- Autónomo tax forms (for example 303 and/or 130, when applicable) — usually quarterly, on the income from your own activity.
What to prepare
- Your informe de vida laboral — it shows the alta in both schemes.
- Your contribution bases: the salaried one (from your nómina) and the RETA one.
- NIE and a certificado digital/Cl@ve — for Import@ss.
- For non-EU nationals — the document proving the right to cuenta propia.
How to set it up
- Keep your salaried job (the alta in the Régimen General runs through your employer).
- Register as self-employed in the RETA (Import@ss), stating the start of the activity.
- At registration, request the general reduced cuota if you qualify; the excess-contribution refund is checked separately after regularisation.
- Check/claim the exceso de cotización refund (often de oficio, but worth confirming).
- 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 the salaried job exempts you from the self-employed contribution (cuota de autónomo) — it doesn’t, you pay both schemes.
- Not claiming/checking the exceso de cotización refund — you lose money.
- Confusing the reduced cuota/tarifa plana with the excess-contribution refund — they are different mechanisms.
- Not declaring your self-employed income through the forms that apply — it is separate from the nómina.
- Non-EU: starting cuenta propia without a status that grants the right to self-employment.
Debts and disputed charges
- Not paying the RETA cuota triggers a recargo and a Social Security debt — the salaried job does not shield you.
- If the exceso refund did not arrive, file a claim with your vida laboral and bases.
- For a dispute over the amount/right, gather documents and file a justification; for a debt, request an aplazamiento.
- Keep the justificantes of the alta and your nóminas.

Frequently asked questions
Do I pay the self-employed contribution if I have a job?
Yes. Dual activity means contributing in both schemes; a salaried job does not exempt you from the RETA cuota.
Can I get part of the contributions back?
Yes — the devolución por exceso de cotización, if your common-contingency contributions exceed the annual threshold set for that year. It is often processed automatically.
Tarifa plana or the excess refund?
They are not the same. The reduced cuota is requested at alta if you qualify; the devolución por exceso is calculated later if common-contingency contributions exceed the annual threshold.
Will I have healthcare twice?
You already have healthcare through the salaried job; self-employment mainly adds to your pension.
Do I file taxes separately?
Yes, your self-employed income is declared through the applicable forms (for example 303 and/or 130) and the Renta, separately from the nómina withholdings.
Can a non-EU national combine?
You need a status that grants the right to cuenta propia. A salaried contract alone does not grant the right to self-employment.
Does it affect my pension?
Yes, contributions in both schemes count; the recalculation rules depend on your record in each.
