25M+ multi-state filers annually (remote workers, students, movers, equity recipients)
The Problem

Workers who earn income across multiple states — remote employees, interns, students on visas, RSU recipients, and frequent movers — struggle to determine which states have taxing jurisdiction over their income. Existing tax software like TurboTax and Sprintax produce confusing or incorrect multi-state allocations, leaving users unsure whether they're over-filing, under-filing, or misallocating income between states.

Potential Solution

A guided SaaS tool that maps a user's physical location history and income events throughout the year to each state's specific sourcing rules, residency tests, and reciprocity agreements. The tool generates a clear state-by-state breakdown of filing obligations, allocates income correctly across returns (including edge cases like RSUs, stock options, gambling winnings, and employer errors), and either produces ready-to-file returns or integrates with existing filing platforms to correct allocations.

Why Now?

Remote work, cross-state internships, and equity compensation have dramatically increased the number of individuals with multi-state tax exposure, while IRS and state enforcement of nonresident obligations is intensifying. The existing tax software market has not kept pace with these complex sourcing scenarios, creating a clear gap exploited by costly errors and audit risk.
