A new 30-day e-visa will be available to tourists arriving from more than 160 countries.
Fees will range from US $10 (£8) to $80 (£65) based on duration and also when visitors choose to visit the country.
Tourists from countries with which India already has an e-visa arrangement, which includes the UK and Ireland, will pay US $10 (£8) for a 30-day e-visa in lean season (April to June) and US $25 (£20) in peak season (July to March).
A one-year e-visa will cost US $40 (£33), rising to US $80 (£65) for a five-year e-visa.
Visitors from Japan, Singapore and Sri Lanka will benefit from reduced fees, while there will be no fee for tourists arriving from Pacific Island nations, as well as a handful of other countries including Argentina, Indonesia, South Africa and Uruguay.
Tourism minister Prahlad Patel said the move aimed to encourage more overseas tourists to visit India.
