Tax engines
TaxScout is integration-first. The objective is a reliable handoff into the professional tax software you already license — not a replacement for it, and not an independent filing engine.
TaxScout e-files supported federal and state returns through IRS MeF under your firm's EFIN — or hands approved data to the professional tax software your firm already uses. E-file coverage is published per return type, and nothing is transmitted before the reviewer approves and the 8879 is signed.

The first adapter is selected by real design-partner demand and access to a licensed validation environment. So we ask every firm the same question:
