Lease rent TDS exemption for aircraft leasing units in IFSC applies subject to prescribed declaration and limited tax years. No deduction of tax is required on lease rent or supplemental lease rent paid to a unit located in an International Financial Services Centre for lease of an aircraft, subject to the unit furnishing the prescribed statement-cum-declaration. The lessee may stop deducting tax only after receiving the declaration and must report the exempted payments in the prescribed tax deduction statement. The relaxation applies only for the twenty consecutive tax years declared for the deduction under section 147, and tax remains deductible for any other year.
