I have linked a valuable reference took to assess US sales and use tax risk that will be helpful in understanding the differences between the “sales” and “use” components as well as the controls and systems necessary to control such risks in a Sarbanes Oxley “SOX” environment.
Most importantly, the tax function needs to be involved in monitoring contracts in which this risk may be evident, prior to execution of the document. Sometimes, the sales/use tax function may not be a tax function, albeit within finance or the controllership area. However, this area of tax is increasingly subjective, complex and requires the input of technical internal/external advisors to avoid large surprises and audit assessments across the country.
Additionally, foreign corporations may also want to review any inbound US activities, and related contracts, to assess potential US sales/use and state income tax obligations due to “nexus” within the borders of a state.
