What is a Tax Residency Certificate (TRC)?

I have filled out an application to get a Tax Residency certificate, for which I have submitted my filled application to the resident country's tax authority office, and attached and provided all the supporting documents like a copy of a passport, copy of proof of address, and tax returns, then after the successful verification of all the documents, the Tax Authority issues me my Tax residency certificate with all the information in it, such as, name, residency period, tax identification number, and nationality.

A tax residency certificate has several benefits, which are: 

• It helps you to avoid double taxation with the help of DTAA. The TRC, NRIs, can get tax benefits under the DTAA between the residence country and India. It ensures that they are not taxed twice on the same income. 
• A Tax residency certificate helps in reducing tax liabilities in the country of residence and India. TRC helps the NRI to lower tax burdens on the income they are generating in India. 
• A TRC allows eligibility to get the lower tax rates, interest, dividends, and capital gains from under tax treaties.  
• TRC helps the NRI to file an IT return easily and get the tax exemptions on the income that they generate from outside India.
