He said the collection of revenue is critical to the task of nation building.
Citing Chanakya, Kovind said a government should collect taxes like a honeybee, which collects just the right amount of nectar from flowers so that both can survive.
Kovind was addressing probationers of the 67th (2015) batch of the Indian Revenue Service (Customs and Central Excise) who called on him at the Rashtrapati Bhavan today.
He said that in a sense the young officers would drive the Goods and Services Tax, which he termed as the biggest economic reform since Independence.
"It also, unfortunately, creates avenues for fraud and money laundering. It is their job to promote economic activity and curb fraud. Both these goals are important," a statement from the Rashtrapati Bhavan quoted the President as saying.
He told the probationers that work they do has implications for India and for India's reputation in the world -- as a trusted business destination, with a fair and predictable tax regime.
