Fill out TGSS forms
with AI.
TGSS forms are official documents issued by the Tesorería General de la Seguridad Social, the Spanish agency responsible for managing Social Security contributions and payments. These forms cover a range of administrative procedures related to Social Security obligations, from registering as a contributor to authorizing direct debit payments. One of the most commonly needed documents in this category is the TC 1/15-3, the SEPA direct debit mandate that allows employers, self-employed workers, and other obligated parties to set up, modify, or cancel automatic bank payments for their Social Security contributions.

About TGSS forms
Anyone required to pay Social Security contributions in Spain may need to complete a TGSS form at some point — whether they are setting up a new direct debit arrangement, updating their banking details, or canceling an existing domiciliation. Getting these forms right matters, as errors or missing information can lead to payment failures, penalties, or delays in processing by the TGSS and the associated financial institution.
Because many TGSS documents are distributed as non-interactive PDFs, filling them out accurately can be more time-consuming than it should be. Tools like Instafill.ai use AI to complete these forms in under 30 seconds, handling the required fields accurately and securely — a practical option for individuals and businesses who need to submit paperwork without the hassle.
