The Los Gatos, California-based company has previously used India as a testing ground for new features, launching a mobile-only monthly plan starting at 199 rupees ($2.79) this year.
Including the mobile plan, the company currently offers four plans in India, with its premium plan costing 799 rupees per month.
"We believe that our members may value the flexibility that comes from being able to pay for a few months at once. As always, this is a test and we will only introduce it more broadly if people find it useful," a spokeswoman for Netflix India said in an email, but declined to give further details.
The U.S. video streaming company is spending $15 billion on content as it battles Amazon.com Inc's Prime Video service, Hulu, and Disney's newly launched streaming service for subscribers.
Netflix Chief Executive Officer Reed Hastings said last week the company was spending about $420 million on content for India, where it has already launched original series such as gangster drama "Sacred Games" and police procedural "Delhi Crime".
Speaking at a media conference in New Delhi, Hastings also said the company's first animated series from India, "Mighty Little Bheem", had been watched by 27 million households worldwide, in a sign of the country's importance to Netflix's plans for global expansion.
