Reclamación de deuda de la Seguridad Social: unpaid quotas, formally demanded

This is a formal demand for unpaid social-security contributions — typically an autónomo's monthly quota that a direct debit failed to collect, or an employer's unpaid cotizaciones. It states the principal plus the legal surcharge and opens a fixed payment window.

How serious: needs actionAlso called: reclamación de deuda TGSS, deuda con la Seguridad Social, reclamación de cuotas

The reclamación lists the periods owed, the principal, and the recargo applied. It is the step before the TGSS's own providencia de apremio — the enforcement order.

Unlike tax debts, the surcharge escalation here is steep: up to 35% once the reclamación's window closes.

A very common origin is mundane: a failed direct debit, a wrong bank account, or missed alta/baja dates in the autónomo registration. The debt is real even when the cause was a banking detail.

Who sends it

The Tesorería General de la Seguridad Social (TGSS) — the treasury of Spain's social-security system, which collects the monthly contributions (cuotas) of employers and the self-employed (autónomos).

Letterhead of the Tesorería General de la Seguridad Social (Ministerio de Inclusión, Seguridad Social y Migraciones); the title 'RECLAMACIÓN DE DEUDA'. It lists the régimen (for example RETA for autónomos), the periods owed, the principal, the recargo percentage, and the payment deadline. It is usually delivered electronically (SEDESS/DEHú), since autónomos and companies are obliged to the electronic channel.

The deadline

LGSS art. 33.3: notified between the 1st and 15th of a month → pay until the 5th of the following month; notified between the 16th and month-end → until the 20th of the following month

LGSS art. 33.3, counted from the date of notification: notified between the 1st and 15th of a month, payment is due by the 5th of the following month; notified between the 16th and month-end, by the 20th of the following month.

If you do nothing

If the reclamación's window passes without payment, the recargo jumps to 35% of the debt (LGSS art. 30.1.b.2º — for quotas the TGSS had to liquidate itself; 20% applies if payment arrives before the window closes) and, once the reclamación is final, the TGSS issues a providencia de apremio to seize assets (LGSS art. 38.1). Interest also becomes payable.

How it escalates

  1. 01The recargo escalates per LGSS art. 30: 10%/20% for declared-but-unpaid quotas; 20% rising to 35% for reclaimed debts once the reclamación window closes.
  2. 02A providencia de apremio is issued (LGSS art. 38.1) with a 15-day final warning before embargo.
  3. 03Embargo of bank accounts, income and property by the Unidad de Recaudación Ejecutiva (LGSS art. 38.5).
  4. 04For autónomos, sustained non-payment can also affect benefit entitlements that require being up to date with contributions (estar al corriente).

Your options, procedurally

  • Payment can be made within the art. 33.3 window through the electronic payment services of the Seguridad Social sede, including card payment.
  • A recurso de alzada can be filed within one month (Ley 39/2015 art. 122.1); under LGSS art. 33.5 the alzada suspends collection only if the debt is guaranteed with aval or its amount is deposited — and if the alzada is rejected, there are 15 days from notification of the rejection to pay before apremio.
  • An aplazamiento of the social-security debt can be requested (possible for most quotas; it prevents apremio while in force).
  • The underlying cause can be checked and fixed in the SEDESS portal — a failed direct debit, a wrong bank account, missed alta/baja dates.

Common questions

How much does the surcharge add?

It escalates under LGSS art. 30: 20% applies if payment arrives before the reclamación's window closes, and it jumps to 35% for reclaimed debts once that window passes. Interest also becomes payable.

Does appealing pause the collection?

Only conditionally: under LGSS art. 33.5, a recurso de alzada suspends collection only if the debt is guaranteed with aval or deposited. If the alzada is rejected, there are 15 days from notification of the rejection to pay before apremio.

The direct debit simply failed — is the debt still real?

Yes. The demand stands regardless of the cause, and the underlying issue (failed domiciliación, wrong account, alta/baja dates) can be checked and fixed in the SEDESS portal.
