The Income Tax Act, 1961 specifies that any lease transaction for not less than 12 years or any sale transaction, above a prescribed transaction value limit tax, has to undergo a clearance process from the appellate body known as the Income Tax Appropriate Authority, constituted under the Income Tax Act. A joint application by the parties involved in the transaction is submitted along with processing fees to the Income Tax Authority, which takes upto a maximum of three months to grant the clearance, without which the sale transaction is not complete. This procedure is popularly known as the 37-(I) clearance, which is the application form number used for this purpose.
