If you're looking for the official platform to submit bulk Form 145 declarations, you should use the Income Tax Department's e-Filing Portal. It is the only government-authorised portal for filing Form 145 electronically under the Income-tax Act, 2025. The portal supports both online filing and bulk uploads through the Common Offline Utility.

What Can You Do on the Portal?

The portal allows taxpayers to:

  • File Form 145 online.
  • Upload bulk Form 145 files prepared through the Offline Utility.
  • File Form 146 (for Chartered Accountants).
  • View filed forms.
  • Download acknowledgements.
  • Check filing status.

How to Access Bulk Filing

After logging in:

1. Go to e-File.

2. Select Income Tax Forms.

3. Click File Income Tax Forms.

4. Choose Forms as per Income Tax Act, 2025.

5. Select Form 145.

6. Choose Offline/Bulk as the filing mode.

7. Upload the file generated from the Common Offline Utility.

8. Complete e-verification.

Preparing Bulk Data

The government portal accepts upload files generated through its official Offline Utility. Many businesses first prepare and validate their data using automation platforms such as 145146.com, then upload the final file through the Income Tax Department's portal.

Conclusion

The Income Tax Department's e-Filing Portal is the official destination for submitting bulk Form 145 declarations. While specialised software can simplify preparation and validation, the statutory filing must always be completed through the government portal.
