Before you can file Form 145 for a foreign remittance, you must first register on the Income Tax Department's e-Filing Portal. Registration is a one-time process that gives you access to statutory forms, income tax services and electronic verification facilities.

Whether you're an individual, company, LLP, partnership firm or tax deductor, registration is mandatory before you can submit Form 145 online.

Who Needs to Register?

You should register on the e-Filing Portal if you are:

  • An individual making a foreign remittance.
  • A company remitting funds to a non-resident.
  • A partnership firm or LLP making overseas payments.
  • A tax deductor (TAN holder).
  • A Chartered Accountant who will file Form 146 on behalf of a client.

Only registered users can access and submit Form 145 electronically.

Documents and Information Required

Before starting the registration process, keep the following ready:

  • PAN (or TAN, where applicable).
  • Aadhaar (where applicable).
  • Mobile number.
  • Email address.
  • Business details (for non-individual entities).
  • Authorised signatory details (for companies and LLPs).

Keeping these details ready helps complete the registration without interruption.

Step 1: Visit the Income Tax e-Filing Portal

Open the official Income Tax e-Filing Portal and click Register on the home page.

Always use the official government website for registration to ensure your information is submitted securely.

Step 2: Select the Appropriate User Category

Choose the category that applies to you, such as:

  • Individual
  • Company
  • Partnership Firm
  • LLP
  • Trust
  • Tax Deductor (TAN)
  • Chartered Accountant

Selecting the correct category ensures that the appropriate registration process is followed.

Step 3: Enter Your PAN or TAN

Provide your:

  • PAN (for individuals and most business entities), or
  • TAN (for tax deductors).

The portal validates these details before allowing you to continue.

Step 4: Verify Your Contact Details

Enter your:

  • Mobile number
  • Email address

The portal sends verification codes (OTPs) to confirm your contact information.

Once verified, your contact details become part of your e-Filing profile.

Step 5: Create Your Login Credentials

Choose:

  • A secure password.
  • Security questions (if prompted).

These credentials will be used every time you log in to file Form 145, Form 146 and other income tax forms.

Step 6: Complete Your Profile

After registration, update your profile by verifying:

  • Address
  • Business details
  • Bank account (if applicable)
  • Key person information
  • Authorised signatory details

Keeping your profile updated helps prevent filing and validation issues later.

Step 7: Log In and Access Form 145

Once registration is complete:

  • Sign in using your User ID and password.
  • Navigate to:

e-File → Income Tax Forms → File Income Tax Forms

  • Select Forms as per Income Tax Act, 2025.
  • Search for Form 145.
  • Choose the applicable filing mode (Online or Offline) and begin the filing process.

Can You File Form 145 Immediately After Registration?

Yes. Once your registration is complete and your account is active, you can access Form 145 immediately, provided you have:

  • Determined the taxability of the remittance.
  • Calculated the applicable TDS.
  • Collected supporting documents such as the Tax Residency Certificate (TRC) and Form 41, where required.
  • Obtained Form 146 from your Chartered Accountant if Part C applies.

Managing Large Volumes of Form 145

The government portal is the official platform for filing Form 145. However, businesses handling hundreds or thousands of foreign remittances often prepare their data using specialised compliance platforms such as 145146.com

These platforms can help with:

  • Bulk Excel import.
  • Validation of mandatory fields.
  • Bulk JSON generation.
  • Workflow approvals.
  • Preparation of Form 145 and Form 146.

The final statutory submission is still completed through the Income Tax Department's e-Filing Portal.

Common Registration Mistakes to Avoid

Before filing Form 145, make sure you:

  • Register under the correct user category.
  • Use the correct PAN or TAN.
  • Verify your mobile number and email address.
  • Keep your profile information updated.
  • Ensure authorised signatory details are accurate for business entities.

These simple checks can help avoid login and filing issues later.

Conclusion

Registering on the Income Tax Department's e-Filing Portal is the first step towards filing Form 145 electronically. Once your account is created and verified, you can access Form 145, complete the required details and submit the form online or through the official offline utility.
