Gavel leaning against a row of law books

ITR looks at the most important trends in tax controversy and how taxpayers can best adapt their strategies for potentially costly disputes.

Multinational companies are battling new sources of controversy from around the world, while old problems are not going away either.

Every business fears the possibility of a major court case costing its reputation and much more financially. Tax controversy is one of the hottest areas of corporate litigation since governments and tax authorities have cracked down on tax avoidance.

With exclusive insight from leading tax professionals at companies and advisory firms globally, this special report looks at how business and tax leaders can:

· Mitigate and manage tax controversy;

· Prevent and resolve disputes; and

· Review the implications of major cases

Here, we have a three-part special report written by Euan Healy, Josh White and Ralph Cunningham:

· Top tax controversy cases in 2023, so far

· The changing face of dispute strategy

· Why more tax controversy is in the offing

The first part is a feature looking at the most important tax disputes in 2023, followed by an article on dispute prevention and resolution strategies. The third part is an analysis of the driving factors of tax controversy.

This is the second in a series of ITR special reports on the most important issues in international tax. You can read the previous one here.
