US nonresidents struggle to correctly report investment income on tax returns due to complex, unclear IRS requirements

US nonresidents holding US stocks face confusion and anxiety about properly reporting dividend income on their tax returns, as IRS rules differ significantly from resident requirements and are poorly documented. They lack clear guidance on which forms to file, tax treaty implications, and withholding obligations, forcing them to either hire expensive tax professionals or risk penalties and audits. Current solutions (IRS website, generic tax software) don't address the specific nonresident scenario, leaving this population underserved and stressed.
