Form 145 Part B applies to a specific situation: the foreign remittance is taxable, the payment or aggregate exceeds ₹5 lakh during the tax year, and the taxpayer has obtained the required certificate or order from the Assessing Officer.

When Does Part B Apply?

Rule 220 provides for Part B where:

  • The payment is chargeable under the Act;
  • The payment or aggregate exceeds ₹5 lakh during the tax year; and
  • A certificate or order has been obtained from the Assessing Officer under the relevant provision.

What Is the Role of the AO Certificate?

The Assessing Officer's certificate/order determines the applicable withholding position in the circumstances covered by the relevant provision.

Once the required certificate/order is available, the taxpayer can furnish the corresponding information through Part B.

Example

An Indian company has to make a foreign payment of ₹12 lakh.

The transaction is taxable and exceeds the ₹5 lakh threshold.

The company obtains the applicable AO certificate/order.

The filing route is then:

AO certificate/order → Form 145 Part B → Submission → Remittance process

Do You Need Form 146?

No.

This is one of the important changes under the new rules.

Where Part B has been furnished, the taxpayer does not also have to furnish Part C or obtain Form 146.

Why Is This Important?

It avoids duplicate certification.

A taxpayer should therefore not assume that every taxable foreign remittance above ₹5 lakh automatically requires a CA certificate.

There are separate routes under the rules.

Final Takeaway

Think of Part B as the Assessing Officer certificate route for qualifying taxable remittances above ₹5 lakh.

Above ₹5 lakh + AO certificate/order = Part B

And if Part B is used, Form 146 is not additionally required
