Interest under section 75: higher rate for tax collected but unpaid, lower rate for other delayed payments. Prescribes rates of simple interest for delayed payment of service tax under section 75 of the Finance Act, 1994, superseding the 2014 notification. It distinguishes between amounts collected as service tax but not paid by the due date and other delayed payments, fixing a higher simple interest rate for the collected-but-unpaid situation and a lower rate for other delays. The notification becomes effective upon assent to the Finance Bill, 2016, and applies prospectively except as to past actions.
