Indian Revenue Service officials of the Income Tax department will donate their one day's earnings to relief fund for the Uttarakhand rain and flash floods affected people.

The I-T officials have been asked to send their contributions to a designated bank account in the national capital which will later be sent to the Prime Minister's relief fund, a senior official said.

The IRS cadre of the I-T department has more than 4,000 members and officials across the country.
