Choose the right procedure
Use TA.4 or the online rectification service when your vida laboral contains errors or omits a period. First obtain a recent report and identify the exact discrepancy. This is a correction request; it does not automatically establish entitlement to a pension or add overseas work as Spanish employment.
What to prepare
Gather identification, NUSS, the report and evidence of the disputed dates or employer: contracts, payslips or other relevant records. Explain which entry should change and why. Keep originals and send the copies requested by the official channel.
Spanish fields explained
Datos del afiliado identifies the worker; otros números de Seguridad Social records other numbers held. Relación de empresas lists the relevant employers with province and alta/baja dates. The form allows approximate or incomplete dates where necessary; make the uncertainty clear rather than inventing dates.
How to submit
Use the official Rectificación de informe de vida laboral service with an accepted identity method. The service is for an identified natural person. Alternatively, ask a TGSS office about presenting TA.4 and supporting evidence. Follow its appointment and delivery instructions.
After submission
Save the submission receipt and respond to any request for evidence. TGSS assesses the correction; the request alone does not change the report. Obtain a fresh vida laboral afterwards and compare the affected entries with the decision.
