A: Sprintax Calculus is backed by a combination of tax experts and developers that are dedicated to the review and release of new tax updates and implementation of any changes that may occur annually or occasionally.
Our team has been receiving IRS and industry updates for more than twenty years, and updating our services and product output as a result. As such, the software meets all foreign national tax law standards in the U.S. and will provide accurate information and updates on tax treaties and other tax updates relevant to foreign nationals.
Tax treaty eligibility and denials are coded into Calculus with results depending on the combination of residency status, income type, cumulative income level, length of time in the US as well as expected duration in the US, visa type and many more details. The specific details of each of the tax treaty conventions between the US and third countries, are all coded into Calculus.
