No Bill or amendment that imposes/varies a tax states have an interest in, redefines "agricultural income" for income-tax purposes, affects state revenue-distribution principles, or imposes a Union surcharge, can be introduced in Parliament except on the President's recommendation.
This gives the executive government (through the President's recommendation requirement) a gatekeeping check specifically over legislation that would affect how much tax revenue states actually receive - ensuring such consequential fiscal-federalism changes go through executive review before Parliament can even consider them.
A private member's Bill in Parliament proposing to change how tax revenue is shared between the Union and states cannot even be formally introduced without first getting the President's (in practice, the government's) recommendation.
