How Do I Verify Bulk Form 145 Submission for Accuracy Before Filing?

When preparing Form 145 in bulk, even a small error can result in rejected filings, incorrect TDS deductions, delays in foreign remittances or additional compliance work. That's why verifying your data before filing is just as important as preparing the forms.

Whether you're a Chartered Accountant, finance professional or corporate tax team, following a structured review process can help ensure that your bulk Form 145 submission is accurate and complete.

Why Verification Is Important

Bulk filings often contain hundreds or thousands of transactions. A single incorrect field—such as an invalid PAN, wrong RBI Purpose Code or incorrect TDS rate—can affect one or more records in the upload.

Performing a final verification helps:

Reduce validation failures.
Minimise manual corrections.
Improve filing accuracy.
Avoid delays in foreign remittances.
Ensure supporting documents match the information reported.

Step 1: Verify the Remitter Details

Start by checking the details of the person or entity making the remittance.

Confirm that:

PAN is correct.
Name matches the PAN records.
Address and contact information are updated.
The correct financial year and tax year have been selected.

Errors in the remitter's details can lead to processing issues.

Step 2: Review the Remittee Information

Check the recipient's details carefully.

Verify:

Name of the non-resident.
Country of residence.
Tax Identification Number (where applicable).
Address.
Bank details, if required.

These details should match the supporting agreements and invoices.

Step 3: Confirm the Nature of Payment

Ensure that every transaction has been classified correctly.

Common payment categories include:

Royalty
Interest
Dividend
Technical services
Consultancy
Commission
Import of services
Foreign vendor payments

An incorrect classification may affect both TDS and the applicable reporting requirements.

Step 4: Review TDS Calculations

Before filing, verify that:

The correct tax provisions have been applied.
DTAA benefits have been considered, where eligible.
The withholding tax rate is accurate.
Grossing-up has been performed where required.
The tax amount has been calculated correctly.

This is one of the most critical areas of Form 145 compliance.

Step 5: Check DTAA Documentation

If treaty benefits are being claimed, confirm that all required documents are available.

These may include:

Tax Residency Certificate (TRC).
Form 41, where applicable.
Supporting declarations.
Any additional documents required to substantiate treaty eligibility.

Missing documentation can affect the application of a reduced tax rate.

Step 6: Verify RBI Purpose Codes

Each foreign remittance should be mapped to the correct RBI Purpose Code.

Check that:

The selected code matches the actual nature of the payment.
The invoice description and purpose code are consistent.
Internal payment records align with the selected code.

Incorrect purpose codes can lead to queries from the Authorised Dealer (AD) Bank.

Step 7: Validate Form 146 References

Where Part C of Form 145 applies, verify that:

Form 146 has been filed successfully.
The correct acknowledgement number has been entered.
The remittance details in Form 145 match those reported in Form 146.

Any mismatch between the two forms should be resolved before filing.

Step 8: Remove Duplicate or Incomplete Records

Before generating the filing data:

Remove duplicate transactions.
Complete any missing mandatory fields.
Review unusually high or low remittance values.
Ensure there are no blank records or formatting errors.

This helps reduce the likelihood of validation failures during upload.

Step 9: Use Automated Validation Tools

Manual review is effective for a small number of forms, but it becomes challenging when processing large volumes.

Many organisations use specialised software such as 145146.com to automate pre-filing verification.

These platforms can assist with:

Bulk Excel validation.
Mandatory field checks.
Duplicate detection.
Data consistency reviews.
Bulk JSON generation.
Workflow-based approvals before submission.

Automation reduces manual effort and helps identify issues before the files are uploaded to the Income Tax e-Filing Portal.

Practical Example

A multinational company is preparing 850 Form 145 filings for foreign service providers.

Before submission, the tax team performs a structured review and discovers:

12 transactions with incorrect RBI Purpose Codes.
8 remittances missing TRCs.
5 duplicate vendor records.
3 transactions where the TDS rate was incorrectly applied.

After correcting these issues, the company generates the final filing files and completes the submission with significantly fewer validation errors.

Pre-Filing Verification Checklist

Before filing bulk Form 145, ensure that you have verified:

✔ Remitter details.

✔ Nature of payment.

✔ TDS calculations.

✔ DTAA eligibility.

✔ TRC and Form 41 documentation.

✔ RBI Purpose Codes.

✔ Form 146 acknowledgement (where applicable).

Conclusion

Accurate data is the foundation of successful bulk Form 145 filing. By following a structured verification process and using automated validation tools where appropriate, businesses can reduce errors, improve compliance and minimise delays in foreign remittances. Investing time in pre-filing verification is often far more efficient than correcting mistakes after submission.
