Taxation and development – consider ways in which
taxation influences the development path of countries:
• Economic activity (level and allocation of investment)
• Financing of key public expenditures (economic, social)
• Accountability of government
• Voluntary compliance of taxpayers
• Market participation (above-ground economy)
Efforts to improve voluntary compliance of individuals
Approaches to curb aggressive corporate tax planning (tax
compliance by banks)
Taxation and development (key linkages):
- level of economic activity, investment
 Taxation (policy, administration, compliance) plays a fundamental
role in shaping economic and social development –
consider various influences (1-5):
1. Tax policy (selection of taxes, tax mix, tax rates and base),
tax administration, and tax compliance can positively or
negatively influence economic activity (income/GDP).
 Some tax systems are less distorting (more efficient) to the
level and allocation of capital:
• Stability, transparency, predictability
• Tax mix (consumption tax, residential property tax vs. income tax)
• Tax design (low rate, broad base, limited use of incentives)
• Factors influencing tax compliance
3
Taxation and development:
-- tax revenues to fund public expenditures
2. Taxation establishes amount of tax revenue to be raised
to fund public expenditure on key programmes important
to attracting investment and social policy:
•
•
Infrastructure, education, health care, property rights
Unemployment, social welfare, housing
 Note: tax incentives for investment given on discretionary
basis, other incentives found to be inefficient and favouring
high net worth individuals -- can be detrimental to
economic development by:
• Misallocating resources
• Eroding tax revenues
• Discouraging voluntary tax compliance
4
Taxation and development:
-- accountability of government
3. Taxation influences the level of accountability of
government over use of public funds (efficient/equitable?)
-- accountability influences:
• Taxpayer compliance
• Business participation in the market (above-ground) economy.
 Some tax systems exhibit high degree of accountability:
• Broad taxpayer base (e.g. consumption tax) – diverse vested
interests, broad-based social contract, pressure on government to
act in interest of citizens collectively
 Some tax systems exhibit low degree of accountability:
• Narrow taxpayer base (e.g. heavy reliance on resource taxation) –
can inhibit transparency, invite corruption, misuse of public funds
5
Taxation and development:
-- fairness/efficiency encouraging compliance
4. Features of tax system (tax mix, design, administration)
influence degree of willingness of individuals and
business to voluntarily comply with a tax system
 Relevant tax-related factors influencing tax compliance:
• Fairness in taxation (sharing of tax burden)
• Tax compliance costs (policy and administration; provisions
recognizing high costs for small firms; use of ICT)
• Government accountability
 Fairness in taxation – where tax system reduces income
inequality, contributes to perception of fairness in sharing
of tax burden, strengthen voluntary compliance
6
Taxation and development:
-- fairness/efficiency encouraging
participation in above-ground economy
5. Features of tax system (tax mix, design, administration)
influence business incentives to operate in above-ground
market economy or shadow-economy
 Relevant tax-related factors:
• Fairness in taxation (sharing of tax burden)
• Tax compliance costs
• Government accountability
 Increased business opportunities (e.g. foreign markets),
business growth where tax system encourages
participation in above-ground economy

Focus of recent OECD work

Recent OECD work elaborates ways in which tax can help
underpin social cohesion and thereby foster economic
development:
• Broad-based taxation to increase government accountability
• Design of tax systems to achieve fairer sharing of the tax burden
(tax mix, tax rates, base provisions)
•
•
•
Progressive PIT rate schedules, basic allowances, provision benefiting
primarily low-income households (e.g. in-work tax credits)
Limited use of personal tax reliefs/incentives benefiting primarily highincome households (e.g. savings incentives)
Taxation of corporate profits (domestic and foreign)
• Measures to ensure tax compliance, steps to contain aggressive tax
planning by high net worth individuals and corporations
8
Encouraging voluntary compliance
of high net worth individuals

In recent years, greater transparency and exchange of
information to counter offshore tax evasion.
Request by G20 leaders – Global Forum on Transparency
and Exchange of Information – reorganized to provide
robust peer review on effective implementation of
standards (start March 2010)
Increased steps being taken by governments to facilitate
voluntary disclosures by taxpayers with undisclosed
income and/or assets.
Offshore Voluntary Disclosure (OECD, 2010) sets out a
framework for successful offshore voluntary compliance
programmes for governments to consider.
Curbing aggressive
tax planning by corporations


Offshore risks include use of no/nominal tax jurisdictions by
closely-held businesses and multinationals to avoid
reporting of taxable income:
• Offshore financing structures
• Offshore holding companies for intellectual assets.
Key challenge of government – addressing aggressive tax
planning by banks, both on their own account and for their
clients:
• Direct revenue losses from leaving unchecked aggressive planning
• Indirect revenue loss where perceptions of unfair sharing of the tax
burden discourage voluntary compliance of other taxpayers
