How it runs
One system of record across all four stages.
Taxbit is tax compliance infrastructure: it collects customer tax details, verifies them, works out who is reportable, and files the reports you owe.
01 Onboard
Collect the documentation and the data.
Data arrives by API, SDK, or file. Tax forms are collected in your product at account opening, and withholding is set at the same time.
02 Verify
Confirm it before it becomes a filing.
US TINs are matched with the IRS in real time. Foreign tax IDs and VAT numbers are checked by format. Anything that doesn't match is flagged immediately.
What Plugs In
Real-time TIN matching03 Determine
Work out who is reportable and on what basis.
Tax lots, cost basis, and income classification all build on onboarding data. Each account gets its form and jurisdiction, with the reason why.
04 Report
File it, deliver it, and handle what comes back.
Forms are filed in each authority's format and delivered to your customers. Corrections and notices are handled in the same system.
