P Chidambaram was the first finance minister to make significant tax changes in an interim budget. In his February 17, 2014 speech, Mr Chidambaram stated that the economic situation at the time demanded interventions that could not wait for a regular budget.

In the interim budget for 2009-10, the then finance minister Pranab Mukherjee announced a six-month extension to a 2 per cent interest subvention on shipment credit for employment-oriented sectors. That involved an additional financial outgo of Rs. 500 crore.
