Global Tax Dispute Resolution Timelines

An interactive tool covering international and national tax disputes resolution timelines across the globe

As a result of the continued growth of tax transparency and global tax co-operation, tax authorities are gaining access to taxpayer information on a previously unimaginable scale, and there has been much focus on the activities of multi-national enterprises. Consequently, we are witnessing a marked increase in the number of tax audits, investigations, and tax cases being contested, many of which are multijurisdictional. In addition, the COVID-19 pandemic and geopolitical volatility has hit economies and markets hard, and the extent and length of economic downturns are still a big unknown. Tax audits, investigations, and controversies are predicted to continue to rise in the coming years as governments may seek to rely on tax law enforcement to mitigate public budget deficits.
