In the mid 2000s, Indonesia’s Directorate General of Taxes (DGT) was still struggling to recover from the shock of the Asian financial crisis of the previous decade. Tax revenue had plummeted during the crisis, and the collection rate remained well below accepted standards, as well as below the standards of many peers in the region. In 2006, the directorate’s new leaders launched a nationwide overhaul, drawing lessons from a successful pilot program that had reorganized the DGT’s biggest offices and enabled large taxpayers to settle all of their tax-related affairs with a single visit to one office rather than having to go through multiple steps. Expanding that pilot to more than 300 locations across a 3,000-mile archipelago presented no small challenge. The implementers built a digital database that linked all offices to a central server in the capital of Jakarta, developed competency testing and training that bolstered the quality of staff, and created new positions to improve relationships with taxpayers. Other measures aimed to reduce corruption and tax fraud. When political and practical crosswinds frustrated the DGT’s efforts to build the workforce its leaders thought it needed, the agency turned to big-data analytics to improve compliance and broaden the tax base. By 2018, domestic revenue mobilization had plateaued, but the changes introduced had produced important improvements. The question was then what to do to broaden the base further without decreasing incentives for investment or raising administrative costs to unsustainable levels.

A complex paper-based city tax collection system made Rio de Janeiro a difficult environment for business and a source of lost revenue when Eduardo Paes became mayor in 2009. Elected on a promise to set the city’s fiscal house in order, Paes planned to implement an electronic invoicing system based on similar programs piloted in other Brazilian cities. A recent constitutional amendment required all levels of Brazil’s federal system of government to ease the burdens of the country’s tax system. Paes reasoned that the potential efficiency gain from a new system was among the few routes available for increasing revenue. His team had to overcome significant challenges to implement the new system and ensure participation by consumers in monitoring tax payments. Strong political and technical leadership, collaboration, and good design helped to successfully implement the new system, called Nota Carioca. This case study offers other governments at the national or subnational levels useful lessons in improving revenue administration and implementing reforms that feature information technology, stakeholder communication, and partnerships.
