Contentious areas include:

  • Tax audits and investigations (domestic and cross-border)
  • Pre-litigation strategy
  • Settlement negotiations with tax authorities 
  • Tax appeals and judicial reviews
  • Tax Treaty disputes and tax-related disputes under Bilateral Investment Treaties
  • Mediation and arbitration of tax disputes
  • Risk assessment and implementation of strategic measures
  • Corporate offences and criminal issues relating to tax evasion
  • Voluntary disclosure procedures
