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.

How to Choose the Right Form
Navigating the requirements of the Tesorería General de la Seguridad Social (TGSS) is essential for any business or self-employed individual in Spain. This category focuses on the financial relationship between you and the Social Security administration, specifically regarding how monthly quotas and payments are processed.
Managing Social Security Payments
If you need to automate your monthly payments or update where your funds are being withdrawn from, you will use the primary document available in this section:
- Tesorería General de la Seguridad Social (TGSS) — Mandato / Orden de domiciliación de adeudos directos SEPA (TC 1/15-3): This is the standard document used to authorize the TGSS to charge Social Security quotas directly to your bank account. It is a critical form for maintaining compliance and avoiding late payment surcharges.
When to Use Form TC 1/15-3
You should select this form if your situation matches any of the following use cases:
- New Registrations: If you have recently registered as an "autónomo" or started a new company and need to set up your first direct debit mandate.
- Changing Bank Accounts: If you are moving your business or personal finances to a different bank and need to update your IBAN with the TGSS.
- Modifying Ownership: If the holder of the bank account where payments are debited has changed, requiring a new formal authorization.
- Cancelling a Mandate: If you need to formally notify the administration to stop a specific direct debit arrangement.
Accuracy Matters
The TC 1/15-3 requires precise financial data, including your Social Security Number (NUSS/NAF) or Contribution Account Code (CCC), as well as a valid IBAN. Errors in these fields can lead to administrative delays or missed payments.
Using Instafill.ai allows you to convert the standard PDF into a smart, interactive form. Our AI helps ensure your data is placed correctly in the required fields, making the process of formalizing your SEPA mandate faster and more reliable than manual entry.

Tips for TGSS forms
The most common error in TGSS mandates is a typo in the bank account numbers. Ensure every digit of your IBAN and the corresponding BIC/SWIFT code is accurate to prevent payment failures and potential late-payment penalties from the Social Security office.
If the person responsible for the Social Security payments is not the owner of the bank account, you must clearly identify both parties. Ensure the account holder provides explicit authorization to avoid the bank rejecting the direct debit request.
AI-powered tools like Instafill.ai can complete these TGSS forms in under 30 seconds with high accuracy. This is a significant time-saver for businesses managing multiple mandates, and you can rest assured that your sensitive financial data stays secure during the process.
Processing a new SEPA mandate or changing bank details can take time within the TGSS system. To ensure your next payment is correctly debited from the new account, submit the form well before the end of the current billing cycle.
Ensure that the Social Security Number (NAF) or Contribution Center Code (CCC) matches your official registration exactly. Any discrepancy between the identification provided on the mandate and the TGSS database will result in an automated rejection of the document.
Always keep a signed, timestamped copy of every TGSS form you submit. Having these records organized digitally allows you to quickly resolve discrepancies with your financial institution or provide proof of authorization during an audit.
