Businesses making multiple payments to non-residents can save considerable time by using the bulk upload feature available for Form 145. Before uploading multiple forms, however, certain prerequisites should be completed to ensure successful processing.

Who Can Use Bulk Upload?

Bulk upload is generally suitable for:

  • Companies making frequent foreign remittances
  • Banks and financial institutions
  • Chartered Accountant firms
  • Shared Service Centres (SSCs)
  • Large corporates processing overseas payments

Prerequisites Before Bulk Upload

Before preparing your upload file, make sure you have:

  • A registered account on the Income Tax Department's e-Filing Portal.
  • Valid PAN or TAN credentials.
  • Complete remitter and remittee information.
  • Correct RBI Purpose Codes.
  • Applicable TDS calculations.
  • DTAA documentation (where treaty benefits are claimed).
  • Tax Residency Certificate (TRC), where applicable.
  • Form 41 (Earlier Form 10F), where required.
  • Form 146 acknowledgement number for Part C filings.

Technical Requirements

The Income Tax Department provides a Common Offline Utility for Form 145 and Form 146 under the Income-tax Act, 2025. The utility allows taxpayers to prepare data offline and generate files for upload through the e-Filing Portal.

Recommended Workflow

  • A typical bulk filing process is:
  • Collect remittance data.
  • Verify taxability.
  • Review TDS and DTAA.
  • Prepare data using the Offline Utility or specialised software.
  • Validate all mandatory fields.
  • Generate the upload file.
  • Upload through the Income Tax e-Filing Portal.
  • Complete e-verification.

Can Software Help?

Yes. Businesses handling hundreds or thousands of transactions often use platforms such as 145146.com to automate data validation, bulk preparation and workflow management before uploading the final files to the government portal.

Conclusion

Meeting the technical and compliance requirements before bulk uploading Form 145 reduces validation errors and improves processing efficiency. Preparing complete and accurate data is the key to a successful bulk filing.
