This workshop discussed how to perform effective and reliable public revenue forecasting analysis, and analyze the impact of tax policies on the economy with the ultimate objective to ensure a healthy fiscal situation.

What did participants learn?

The workshop helped participants better understand the:

  • data requirements and various approaches used to forecast the revenues from different types of taxes and to assess the impact of policy changes
  • different perspectives of institutions involved in revenue forecasting and tax policy analysis
  • importance of timely and effective coordination for developing uniform views on the macroeconomic outlook triggering the revenue forecast, and assessing the revenue foregone through tax expenditures
  • nature and source of underlying macroeconomic assumptions, and scope for discretionary adjustments of forecasts
