FreeTaxUSA E-filing Final Steps Workflow When navigating FreeTaxUSA's final submission flow: dismiss recurring session timeout dialogs before each click, skip optional file attachment uploads (IRS already has data from 1099s), verify prior-year AGI matches exactly, and stop at the Electronic Signature page where both filers must manually enter 5-digit PINs. The 3-step flow is (1) Order Products → (2) Review Tax Return → (3) Submit Tax Return; only the final Submit button is irreversible. ---
