Deregistering as self-employed (baja de autónomo) in Spain: RETA + Hacienda
Stopping your activity? Closing self-employed status (autónomo), like opening it, is TWO bajas: the baja en RETA (Social Security) and the baja censal at Hacienda (modelo 036/037). You must do both, or the cuota or tax obligations keep piling up. There is no formal “pause” — you file a baja and re-register (alta) when you resume. Below: the steps, the deadlines (baja RETA within 3 days), the final quarter of taxes, your right to cese de actividad and how not to end up with a debt.
What a baja is and why there are two
A baja is deregistering as a self-employed worker (autónomo). As with opening, there are TWO of them.
Baja en RETA (Social Security): ends the self-employed scheme and the monthly cuota. Usually via Import@ss or modelo TA.0521.
Baja censal at Hacienda: modelo 036/037 (declaración censal de baja) — you close the activity (epígrafe) and its IVA/IRPF obligations.
You must do BOTH. A baja en RETA without the censal (or vice versa) leaves obligations hanging.
Who needs a baja
- Any self-employed worker who stops their activity — for good or for a while.
- There is no standing “pause”: you file a baja and re-register (alta) when you resume (several alta/baja a year are allowed).
- If you had staff, their contracts and your cuenta de cotización are closed separately.
- If you also have a salaried job (pluriactividad), the self-employed baja does not affect the employee scheme.

What you are entitled to
- To stop paying the RETA cuota from the baja date (filed on time, you pay only for the days you were registered that month).
- The right to cese de actividad (the self-employed benefit) if you meet the conditions — see the dedicated guide.
- The right to re-register (alta) later; your contribution history is kept.
- The right to challenge a wrong debt/recargo and request an aplazamiento (instalments).
Baja deadlines
- Baja en RETA: notify within 3 calendar days of ceasing the activity.
- If you file the RETA baja on time, the cuota is charged only for the days you were registered (the reform pro-rates the alta/baja months).
- Baja censal (036/037): filed when you cease; then the final quarterly returns for the period worked.
- Cese de actividad (if you qualify): you can claim it until the last day of the month after the activity stopped; late filing reduces the benefit period.
What to prepare
- NIE and a certificado digital or Cl@ve — for Import@ss and the AEAT Sede.
- The actual date you ceased the activity.
- The activity (epígrafe IAE) you are closing.
- Documents for cese de actividad if you will claim it (cause of cessation, contributions).
How to close, step by step
- File the baja en RETA through Import@ss (or modelo TA.0521) within 3 days of ceasing.
- File the baja censal at Hacienda: modelo 036/037, marking the end of the activity (epígrafe).
- File the final quarterly returns required for your regime (for example 303/130/131 if applicable) for the period worked — including “zero” returns when they are mandatory.
- If you have grounds, claim cese de actividad (the self-employed benefit).
- Save the justificantes for both bajas and the returns — that is your proof of closure.
Common mistakes
- Doing only the baja en RETA and forgetting the baja censal (or vice versa) → hanging obligations and penalties.
- Missing the 3-day RETA window → extra cuota.
- Not filing the final quarterly forms that apply to your regime (for example 303/130/131).
- Not claiming cese de actividad when you are entitled to it.
- Just stopping payments without filing the baja → a Social Security debt and an embargo.
Debts and how to react
- If you don’t file the baja and stop paying, the cuota, recargo and Social Security debt build up.
- A Hacienda debt (unfiled returns) also grows with penalties — close the censal and file the final modelos.
- You can request an aplazamiento/fraccionamiento of the debt — check the conditions.
- Sometimes there are grounds to challenge an assessment or the baja date — gather your justificantes and notices.

Frequently asked questions
Can I “pause” self-employed status for a while?
There is no formal pause: you file a baja and re-register (alta) when you resume. Several alta/baja a year are allowed.
How many bajas do I need?
Two: the baja en RETA (Social Security) and the baja censal at Hacienda (modelo 036/037). Both are required.
Will I pay the cuota for the whole baja month?
Filed on time (3 days), the cuota is usually charged only for the days you were registered that month.
Is there a benefit when I close?
Possibly — cese de actividad, if you meet the conditions (contributions, cause, record). See the dedicated guide.
Do I still file taxes after the baja?
Yes, if your regime still requires quarterly forms (for example 303/130/131 when applicable), file them for the period worked; annual returns stay on their normal deadline.
What if I just stop paying?
Without a baja the cuota and a Social Security debt build up, up to an embargo. File the baja.
Can I re-register later?
Yes, you file alta again; your contribution history is kept. The right to the tarifa plana depends on the time since your last baja.
