The Stockyards of Fort Worth, TX, June, 2026 — Halcyon®, a financial services innovation company that transforms how lenders verify income, authenticate identity, and manage compliance, today highlighted an update to Fannie Mae’s Selling Guide formally documenting Form 8821 as an accepted alternative to traditional Form 4506-C processes for verifying borrower income (Selling Guide Announcement SEL-2026-06, June 3, 2026).
For lenders using TrueTax™, Halcyon’s IRS-direct income verification product, this update changes nothing about how their files are built; it documents what TrueTax has always relied on. TrueTax verifies income directly from the IRS using the Form 8821 authorization process, the same authorization the Selling Guide now formally documents as an accepted alternative to Form 4506-C for income verification. The update gives lenders using TrueTax documented confidence in a process they have relied on all along.
“This is validation, not a new requirement,” said Kirk Donaldson, CEO of Halcyon. “Lenders using TrueTax have been operating on the Form 8821 standard because it is simply the better way to verify income: IRS-direct, instant, and accurate. Fannie Mae putting that in writing removes any remaining hesitation for lenders considering the move beyond legacy transcript ordering.”
TrueTax replaces traditional 4506-C processes with IRS-direct verification and instant, multi-year access to taxpayer data. Because TrueTax’s flexible ordering requirements eliminate the restrictive conditions that cause legacy rejections, lenders see near-zero error and rejection rates (Halcyon internal data), compared to the 10-25% error and rejection rates common with conventional 4506-C processing (Halcyon internal data). Where legacy methods provide a single point-in-time snapshot and require waiting days for results, TrueTax provides ongoing, repeatable access throughout the loan lifecycle, instantly.
For mortgage lenders, the Fannie Mae update is an opportunity to formalize a workflow that already reduces rejections, shortens closing timelines, and expands confidence in underwriting self-employed and complex-income borrowers. Lenders not yet using TrueTax can move beyond legacy transcript ordering and adopt the same Form 8821-based approach Fannie Mae now documents as standard practice.
