Diagnostics Tool
📚 What This Guide Covers
This guide explains the function and importance of the Diagnostics tool in SureFire. Running diagnostics is a mandatory step before any return can be electronically filed.
📊 Understanding Diagnostics
Diagnostics scan your tax return for errors, inconsistencies, or missing information required by the IRS.
The Diagnostics window is a critical gatekeeper for e-filing. If any Diagnostic Errors are present, the return is considered invalid for transmission and the e-file button will remain disabled.
✅ Resolving Issues
Most Diagnostic Errors are displayed as clickable links. Clicking an error will take you directly to the specific form and field that needs attention, allowing you to quickly resolve the issue.

Once all errors have been corrected and the diagnostics report shows no remaining issues, the return will become eligible for electronic filing.
