The scheme of advance rulings was introduced by the Finance Act, 1993, Chapter XIX-B of the Income-tax Act, which deals with advance rulings, came into force with effect from 1-6-1993. Under the scheme, the power of giving advance rulings has been entrusted to an independent adjudicatory body. Accordingly, a high-level body headed by a retired judge of the Supreme Court has been set up. This is empowered to issue rulings, which are binding both on the Income-tax Department and the applicant. The procedure prescribed is simple, inexpensive, expeditious and authoritative.

Advance Ruling means written opinion or authoritative decision by an Authority empowered to render it with regard to the tax consequences of a transaction or proposed transaction or an assessment in regard thereto. It has been defined in section 245N(a) of the Income-tax Act, 1961 as amended from time to time. Under section 245N, a ruling can be obtained by an applicant (who may be either a non-resident or a resident having a transaction with a non-resident) in respect of any question of law or fact in relation to the tax liability of the non-resident arising out of a transaction undertaken or proposed to be undertaken.
