The Costa Rican Ministry of Finance has announced new security requirements for the Costa Rica cryptographic key, which is used to digitally sign electronic invoices and other electronic tax documents. These measures aim to strengthen the protection of tax information and enhance the security of electronic invoicing processes.

The new requirements will take effect on August 1, 2026, and must be considered by all businesses generating new cryptographic keys for their tax operations.

What Changes for the Costa Rica Cryptographic Key in 2026?

As part of the new security policy, the PIN associated with the Costa Rica cryptographic key must meet the following requirements:

  • Be at least 14 characters long.
  • Include at least one uppercase letter.
  • Include at least one lowercase letter.
  • Include at least one number.
  • Include at least one special character.

These new requirements are designed to reduce the risk of unauthorized access and strengthen the security of the digital signature used in electronic tax documents.

What Will Happen to Existing Cryptographic Keys?

Existing cryptographic keys will remain valid until their expiration date, provided the taxpayer does not revoke them before they expire.

This means businesses will not need to replace their current keys immediately. However, all newly generated cryptographic keys must comply with the new security policy established by the Ministry of Finance.

When Will These Changes Take Effect?

All new cryptographic keys generated on or after July 27, 2026, must comply with the updated security requirements established by the Costa Rican Tax Administration.

As part of the transition period, the Ministry of Finance allowed taxpayers to generate cryptographic keys using the traditional four-digit PIN until July 26, 2026. These keys will remain valid until they expire or are revoked.

Will the Process for Obtaining a Cryptographic Key Change?

No. The process for obtaining the Costa Rica cryptographic key remains unchanged.

Businesses will continue generating their cryptographic keys through the TRIBU-CR platform, following the same process already familiar to taxpayers. The only change is the new set of security requirements for the PIN.
