The Indian budget process involves 4 main stages:
1) Estimates of expenditures and revenues are prepared by various ministries and consolidated.
2) An initial deficit estimate is calculated by matching revenues and expenditures.
3) The deficit is narrowed through tax adjustments or expenditure cuts, mainly to plan expenditures.
4) The budget is presented to Parliament in February and takes effect in April, after parliamentary approval of appropriation and finance bills.
