<h1>Tax deduction relief for non-resident branch operations through a unified Form No. 126 compliance framework.</h1> Form No. 126 is a unified self-declaration and treaty-benefit request for specified non-residents carrying on business or profession in India through a branch to obtain a certificate for receipt of certain sums without deduction of tax at source. Banking companies and insurers, and other eligible non-resident persons, must satisfy the conditions in Rule 209, including tax compliance, branch-based receipt on own account, and, for non-banking applicants, continuous business in India for five years and prescribed fixed assets. The application is filed electronically, processed by the Assessing Officer, and the certificate remains valid for the relevant tax year unless cancelled earlier.
