Pinwheel Taxes API

The Pinwheel Taxes API retrieves W-2, 1099-K, 1099-MISC, and 1099-NEC documents directly from a worker's payroll provider, returning them as both PDF and structured JSON. Tax-prep software, gig platforms, and lenders use it to skip manual uploads, drive faster filing flows, power quarterly tax-estimation tools for 1099 earners, optimize W-4 withholding from historical data, and pull tax-form-based earnings totals into income and employment verification decisions.

Pinwheel Taxes API is one of 12 APIs that Pinwheel publishes on the APIs.io network.

Tagged areas include Tax, W-2, Tax Forms, and Payroll. The published artifact set on APIs.io includes API documentation.
