A guided tax decision tool asks users about visa status, residency tests, country of citizenship, income sources, brokerage accounts, inheritances, and asset sales, then generates a personalized filing checklist with required forms and explanations. It can also produce employer or broker-facing form recommendations, flag CPA^?-review situations, and export organized summaries for tax preparers.

Remote investing, global migration, OPT employment, and cross-border inheritances are increasingly common, while tax platforms remain poorly suited to mixed U.S. and foreign situations. Users are turning to forums because standard broker and tax software workflows do not handle edge cases clearly.
