These areas of taxation naturally intersect with knowledge in HR policies, tax equalisation, assignment planning, social security and payroll compliance.

The focus on US compliance extends to assisting clients who need to catch up with their US tax reporting obligations through the IRS Streamlined or Offshore Voluntary Disclosure Program (OVDP). This in turn can create opportunities for planning including considerations for US expatriation. Dawn has helped many clients bring their US tax matters up to date and has significant experience in this area.
