On 28 August 2026, the Puerto Rico Department of Treasury (Hacienda) published Publication 06-06, establishing the Automated Clearing House (ACH) Credit File Specifications for taxpayers and financial institutions remitting tax payments electronically. This publication serves as the authoritative technical reference for formatting ACH credit transactions directed to the Treasury’s Unified Internal Revenue System (SURI). The specifications are effective immediately and apply to all tax types processed through the SURI platform, including sales and use tax, income tax withholding, and corporate estimated payments. The move aligns with Hacienda’s ongoing digital transformation initiative to modernize tax administration, reduce paper-based processing, and accelerate revenue collection. By standardizing the ACH credit file structure, the Department aims to minimize transmission errors, ensure timely posting of payments, and enhance reconciliation capabilities for both the Treasury and taxpayers. The publication also signals a broader shift toward mandatory electronic payment channels for larger taxpayers, reducing reliance on paper checks and manual data entry.
Key Takeaways
- Standardized Record Layouts and Field Definitions: Publication 06-06 defines the mandatory record formats for ACH credit files, including header, detail, and control records. Each field is specified with precise length, data type, and validation rules, ensuring uniformity across all submitting entities. Taxpayers and payroll providers must adapt their payment generation systems to comply with these layouts to avoid rejected transmissions. The specifications cover critical data elements such as taxpayer identification number, tax type code, tax period, payment amount, and settlement date, all of which must conform to the prescribed format.
- Mandatory Tax Type and Period Identification: The specifications require explicit identification of the tax type, tax period, and taxpayer identification number within each transaction. This granularity enables the SURI system to automatically allocate payments to the correct liability, reducing manual intervention and misapplied credits. Entities must ensure their accounting software captures and maps these data points accurately. Failure to include valid tax type codes or period identifiers will result in the payment being held in suspense, potentially triggering penalties and interest for late payment.
- Testing and Certification Protocol: Hacienda mandates that all new ACH credit submitters complete a pre-production testing phase using a dedicated sandbox environment. Successful certification is required before live submissions are accepted. The publication outlines the test scenarios, expected acknowledgment files, and error code definitions, providing a clear pathway for onboarding. This protocol ensures that transmitters can validate their file generation logic and error handling before moving to production, thereby reducing the risk of systemic failures during peak filing periods.
