  text: This study investigates the determinants of tax complexity in Indonesia, focusing
    on the perspectives of tax officers and firms, and thus provides a case study
    relevant to developing countries. Understanding tax complexity in this context
    is crucial as developing nations frequently encounter legislative, fiscal, and
    administrative challenges that exacerbate their tax complexity. Complexity can
    hinder investment, impair tax revenue collection, and impede economic development.
    The authors adapt a global survey instrument to the Indonesian context and collect
    responses from Indonesian tax officers and firms. Transfer pricing is perceived
    as the most complex tax regulation which is consistent with cross-country studies.
    However, in contrast to the global findings, statutory tax rates and taxes on
    dividends rank second and third in Indonesia. While Indonesian tax officers emphasize
    the complexity of transfer pricing regulations, firms are more concerned about
    the complexity of tax procedures, especially tax guidance and tax audits. Furthermore,
    comparative analyses show that tax officers perceive tax regulations as being
    more complex than tax procedures. In contrast, firms perceive the opposite, particularly
    for tax audits. The findings offer a nuanced picture of tax complexity in a developing
    country and provide guidance for tax reforms in Indonesia. They also serve as
    a commencement for further analyses of developing countries.

  text: 'This study investigates whether, how, and under what conditions the expected
    positive association between cooperative compliance programs and tax compliance
    is attenuated by tax complexity. Many countries have implemented cooperative compliance
    programs to improve compliance, however, the effectiveness of these programs varies
    across countries. I expect and find that the complexity of a country''s tax system
    might impair the compliance-enhancing impact of cooperative compliance programs.
    Using cross-country data of 57 countries, I find that cooperative compliance programs
    generally promote compliance, except in countries with highly complex tax codes.
    Moreover, these programs are positively associated with tax compliance even if
    tax procedures, such as tax filing and payment or tax audits, are highly complex.
    My findings suggest that cooperative compliance programs can compensate for mistrust
    caused by complex tax procedures and enhance compliance. However, they may not
    be effective tools to enhance compliance in complex tax codes. '

  text: This study investigates the association between the political characteristics
    of countries and the complexity of the legal system. We use country-level measures
    of tax complexity, democracy indicators, and election results data and find that
    the degree of democracy is associated with higher overall complexity of tax systems.
    This association is driven by the complexity of tax regulations. Contrastingly,
    we document negative associations with the complexity of tax procedures such as
    tax filings or tax audits. Moreover, we find the association between democracy
    and tax system complexity to be inversely U-shaped, indicating strong autocracies
    and strong democracies to reduce overall tax complexity. In further analyses,
    we document that the complexity of anti-tax avoidance regulations increases with
    higher levels of democracy and demonstrate that left-wing governed countries are
    more prone to experience an increase in complexity through democracy than right-wing
    governed countries.
