Analysts identified the implementation of a goods and services tax (GST) and land purchase reforms as other big factors for the stock market.
The GST would for the first time transform Asia's third-largest economy into a single market, streamlining a myriad of state taxes in a bid to make it easier to do business.
The land acquisition bill would make it easier for businesses to buy land but it has met opposition from farmers.
The two reforms, if passed, would give the biggest boost to the financial services industry and be welcomed by manufacturers after industrial activity fell to a five-month low in February, the poll found.
Uncertainty over the timing of a US interest rate rise is another risk for the Sensex. The latest poll of Wall Street's primary banks forecast the Federal Reserve would tighten in September rather than June as expected earlier.
