Businesses handling a large number of foreign remittances often ask the same question: Do we really have to prepare every Form 145 and Form 146 separately?

For high-volume compliance work, the bulk workflow can make the process considerably more manageable.

The exact steps depend on the form and the filing mode available on the Income Tax e-Filing Portal, but the overall process can be understood in a few stages.

1. Prepare the Transaction Information

First, collect the information required for each transaction.

This may include:

  • Remitter details
  • Remittee details
  • Payment information
  • Tax details
  • TDS information
  • DTAA information
  • RBI Purpose Code
  • Supporting documentation

The data should be checked before it is converted into the required filing format.

2. Complete the Tax Review

Bulk filing does not mean skipping the tax review.

Before generating the forms, determine:

  • Whether the payment is taxable
  • Applicable TDS treatment
  • Whether DTAA relief is being claimed
  • Whether supporting documents are available
  • Whether Form 146 is required

This step is particularly important when a large batch contains different types of payments.

3. Generate the Forms

Once the information has been reviewed, the Form 145 and Form 146 data can be prepared in bulk.

145146.com provides technology for bulk preparation and generation of both forms, reducing the need for repetitive individual data entry.

4. Download the Required Files

The prepared files can then be downloaded and taken through the applicable filing workflow on the Income Tax e-Filing Portal.

This creates a simple separation between:

Preparation → Download → Government Portal Upload

5. Upload Through the Applicable Portal Workflow

The authorised user can log in to the Income Tax e-Filing Portal and follow the applicable form-filing and upload process.

The portal processes the submitted data and provides the relevant filing status or acknowledgement information.

6. Check the Results

After upload, don't assume that every record has been accepted.

For a large batch, check:

  • Successful records
  • Failed records
  • Validation errors
  • Acknowledgement details
  • Records requiring correction

Failed records should be reviewed and corrected before they are resubmitted.

Why Use a Dedicated Bulk Workflow?

Imagine preparing 500 forms manually.

Even if each form takes only a few minutes, the total effort can become substantial.

A structured bulk process reduces repetitive data entry and gives the team a better way to manage the entire batch.

One Solution From Start to Finish

145146.com combines technology with tax assistance.

The service can support the workflow from tax review and data preparation to Form 145/Form 146 generation, downloading and bulk uploading, giving businesses and CA firms one place to manage the process.

Conclusion

Bulk filing is not simply about uploading a large file. The quality of the underlying data and tax review matters just as much.

A reliable process should therefore look like:

Tax Assessment → Data Preparation → Form Generation → Validation → Download → Government Portal Upload → Status Review

That is the approach businesses should follow when handling Form 145 and Form 146 at scale.
