Pros

    K1x

    Private market tax data is broken at every handoff. Fund managers produce K-1s through manual, error-prone processes that delay investors and create downstream liability. Accounting firms receive those same K-1s in volumes that extraction tools only partially handle โ€” leaving footnotes, K-3 schedules, and state allocations for senior staff to close manually. And the entire ecosystem runs on disconnected tools built for general purposes and retrofitted to tax.
