Functioning as an in-house tax executive, Caius Tax Management Solutions is embedded in your team to closely manage your tax affairs. We’ll share responsibility working side-by-side with your finance or tax team, building trust and consistent results every step of the way.


A combination of in-sourcing and outsourcing offers the best of both worlds

For many larger organisations, the sheer complexity of tax structure makes it difficult to manage internally. By working within your team, Caius provides more than just borrowed staff—we become a consistent, on-call presence to bolster your team’s expertise.


Whenever needed, tap into Caius’ tax mastery to perform recurring tax functions:


  • Annual and interim period provision support (preparation or review)

  • Financial reporting and disclosure requirements

  • Valuation allowance and deferred tax assessments

  • Accounting for uncertain tax position assessments (ASC 740-10 and IFRIC 23)

  • Internal controls and supporting documentation



  • Multiple country income-tax filings

  • Withholding compliance

  • Estimated tax calculations and cash management analysis

  • Management of tax audits

  • Provision-to-return analysis

Familiarity breeds innovation
