There are 3 ways tax document issuers can participate in the FDX Tax Ecosystem: (1) API, (2) File Export, and (3) QR Codes
Issuers of annual tax documents (e.g. 1099, K-1, W-2) can make tax preparation simpler for
document recipients by offering download in both human and computer readable formats.
If your bank, brokerage firm, or other institution is planning on migrating from
OFX to FDX, there are tools to make the task simpler.
