What this document is
TA.2/T (“Solicitud de alta, baja o variación de datos del trabajador/a por cuenta ajena — a instancia del trabajador/a”) is an official form of Spain’s General Social Security Treasury (TGSS). With it an employee reports that they started work (alta), stopped working (baja) or that their data changed, when the employer was obliged to report it and did not. The same form is used to cancel a wrong alta or baja.
Normally the employer reports this — on form TA.2/S or online. TA.2/T is for when the employer did not: the employee may request the alta or baja directly (Real Decreto 84/1996, art. 29.1.2º). An alta the employer failed to request on time can be requested at any time after the failure is noticed, and TGSS informs the Labour Inspectorate of such requests (art. 32.3.1º).
Who files it and where
- the employee files it (or their legal representative, who then signs);
- it is addressed to a TGSS Provincial Directorate or Administración, named at the bottom of page 1;
- the form is printed, signed and handed in at TGSS or through any official registry;
- you may enclose documents proving the job — the form has three lines for them.
What the form asks
- the worker: surnames and name, Social Security number (NSS), date of birth, identity document, address in separate boxes, e-mail and mobile;
- what you ask for — alta, baja, data change or cancellation of a wrong alta/baja, the date and a detailed reason;
- what you know about the employer: name, scheme, contribution account code (CCC), last known address;
- for alta or a change — employment data: contract type, contribution group or job category, job description, part-time hours, replacement.
What to bring
- identity document (DNI, foreigner card with NIE; passport only for EU, EEA and Swiss citizens and only for alta);
- proof of the job: employment contract, payslips (nóminas), messages or a letter from the employer;
- proof of representation, if a legal representative files it.
Check the exact list for your case with TGSS. If something is missing, TGSS asks you to complete the application within 10 days (the “Subsanación” block on page 3).
How to fill it in with FoxDocs
Tell the chat where and since when you work and what the employer failed to do. FoxDocs asks only what is needed, words the reason in Spanish, splits the date and address into boxes and repeats the NSS, CCC, request type and date on the receipt on page 3. Section 4 is asked only for alta or a data change. Values are printed in capitals, as the form’s instructions require.
