How long do i have to return the wrongful receipt without being the surcharge applied?

When perceived unduly benefit or unemployment allowance, the public employment service Estatal (SEPE) i shall be within ten days to claim what it considers appropriate.

That period has elapsed, a decision noting whether unduly received a benefit or allowances by unemployment and its size.

The deadline for the return of that amount is 30 days of notification of the resolution of the wrongful receipt.

You must perform the entry into the SEPE told at the same notification.
