In India, there are several ways to pay income tax and file an income tax return:

• Online through the Income Tax Department’s e-filing portal: This is the most convenient and secure way to file an income tax return and make tax payments. Taxpayers can register on the e-filing portal, upload their tax returns, and make payments online using a credit/debit card or net banking.
• Through an authorized bank: Taxpayers can visit a designated bank branch and make a tax payment using a challan. The bank will issue a receipt that serves as proof of payment.
• By mail: Taxpayers can send a demand draft or cheque, along with a completed tax return form, to the relevant Income Tax office.
• In-person: Taxpayers can visit their local Income Tax office and make a tax payment in person.

It’s important to note that taxpayers must file their income tax returns by the due date, which is usually July 31 of each year. Late filing of returns may result in penalties and interest charges.
