Cost-Benefit Analysis of Tax Expenditures and other Revenue Measures

Workshop: April 16 – 18, 2018ILjubljana, SloveniaIApplication deadline: March 23, 2018ITax Policy and Administration

We will discuss how assessment of the tax incentives and other tax expenditures in the region based on their economic usefulness in increasing social welfare would support efforts in reforming the tax system and improving tax revenues. Many countries are in need of rationalizing their system of tax incentives and scaling back other tax expenditures, but lack the analytical and other tools. The workshop on tax expenditure assessment will follow up the 2017 workshop on revenue forecasting and tax policy analysis.

Tax expenditures (TEs) are used by governments around the world to promote public policy objectives and they are designed to promote economic growth and support income maintenance. TEs are offered in many shapes across the entire tax system. They provide subsidies through reduced tax rates, tax exemptions, exclusions, deductions and tax credits. Tax expenditures in the form of tax incentives are extensive and increasing in the region. Cost effectiveness of revenues forgone is measured in terms of economic benefits relative to the indirect subsidy provided by the tax system. The cost-benefit analysis would allow for comparison of the opportunity cost of forgoing tax revenues which could be directed towards alternative uses of public funds beneficial to the society. 

How will you benefit

By the end of the workshop you will be able to:

  • Understand the role of a benchmark for each type of tax. Once the benchmark tax system is determined and tax expenditures in terms of revenues forgone are estimated, their economic usefulness can be determined using a CBA framework
  • Discuss the analytical structure in place to enable an assessment of the economic benefits of such concessions
  • Evaluate the effects of tax-benefit policy reforms and other changes on poverty, inequality, incentives and government budgets by calculating the effects of actual policies
  • Use such analysis to facilitate the preparation of periodic TE budget

What will you learn

By completing the learning initiative you will improve your capacities in the following areas:

  • Advantages and potential adverse effects of TEs
  • Reporting, measurement and review of TEs
  • Integration into the budget process
  • Estimates of tax revenues forgone, and their effect on effective tax rates by type of taxpayers, sector and size of income can be best established using microsimulation models.
  • EUROMOD, a tax-benefit microsimulation model for EU that enables researchers and policy analysts to calculate, in a comparable manner, the effects of taxes and benefits on household incomes and work incentives 

Participants will be actively engaged in discussions and group exercises, and encouraged to share their experiences and country practices. 

Who should attend

The workshop is designed for the officials in ministries of finance and tax administrations who are involved in tax expenditure analysis.

No fee will be charged for officials working in the public sector. Travel and accommodation costs for up to two participants from Armenia, Bosnia and Herzegovina, Bulgaria, Croatia, Georgia, Macedonia, Moldova, Mongolia, Montenegro, Romania and Ukraine will be covered by the Ministry of Finance of the Netherlands. Applications of additional self-funded candidates from the SEE region (and beyond) will be considered, as far as space permits. Meals and refreshments will be provided during the event.
