Founded in 1980, ACAUS is a non-profit organization dedicated to supporting qualified accountants from sixteen Chartered Institutes with members who reside in the U.S.

Our mission is to facilitate the professional success of our members, promote the business community’s recognition of, and respect for, these professionals. Since our founding in 1980, we have worked to achieve this by focusing on achieving increased:

  • awareness and understanding of the Chartered Accountant qualification by the business community
  • value to members and institutes by being a vibrant organization
  • participation by our eligible members in chapter activities and other offerings
  • bench strength (emerging leaders) to sustain the association over time with active volunteers
  • advocate for mutual recognition of our institute qualifications and building relationships with other U.S.-based organizations. As of February 2020, all our foundational institutes bar one have MRAs in place with AICPA/NASBA. The remaining institute – ICAEW – is in active discussion to achieve similar.

David Nickson


Commercially focused partner with over 20 years tax, financing transactional and technology experience. Chartered Accountant (Fellow, ICAEW), Chartered Tax Adviser (CIOT), Six Sigma Black Belt and IRS Enrolled Agent

I integrate technology (SAP, Microsoft, Oracle), accounting/controllership, and tax requirements to increase the efficiency and robustness of E2E business processes, with experience across multiple industry sectors and geography. The business case justification for addressing tax requirements in a holistic manner extends across the organization to include treasury (cashflow enhancement), FP&A (profitability insights), finance operations (process efficiency), internal audit (enterprise risk mitigation), supply chain/logistics, and IT strategy.

Many organizations already faced substantial challenges in the execution and tax reporting of their transactions, but following U.S. tax reform (bringing a significant increase in data granularity required to meet planning, compliance, and monitoring goals) those same organizations are actively considering their ability from both an IT systems and controllership process perspective to meet these obligations. The opportunity to address this, given that so many companies currently are replatforming their ERP systems and at the same time trying to optimize their value chain under new tariff/customs scenarios could never be more timely. I can help you navigate this landscape.
