IRS gets real-time tax preparer credential check to block fraud

What it does

This bill requires the IRS to create a real-time validation system for EFINs (Electronic Filing Identification Numbers)—the credentials that tax preparers and software use to file returns electronically on behalf of taxpayers. Before any return can be filed electronically, the IRS must confirm that the EFIN is active and the person using it is authorized to do so. The bill mandates the IRS build this system within 24 months and report back to Congress on how it works.

Why we flagged it

The bill's core mechanism is a mandatory real-time validation system for tax preparer credentials, designed to prevent unauthorized or fraudulent electronic filing. This is a straightforward security and authentication measure with no hidden agenda or private carve-out.

What the text implies

• The IRS must build and maintain a real-time lookup system that tax software vendors will query millions of times per year, creating operational and cybersecurity burden on the agency.
• Tax preparation software companies will be required to integrate with this new IRS system, imposing compliance costs on the industry—though the bill does not explicitly fund or reimburse them.
• The bill requires the IRS to establish 'administrative, technical, and physical safeguards' to prevent EFIN enumeration or bulk verification, suggesting awareness of potential abuse if the system is compromised.
• Real-time validation may introduce latency or availability risks during peak filing season; the bill requires contingency procedures but does not specify what happens if the system fails.

This protects ordinary people from identity theft, refund fraud, and unauthorized tax filings—a direct public safety gain with no offsetting cost to citizens' rights or remedies.

Who stands to gain

• Tax preparation software vendors (compliance and integration costs offset by reduced fraud liability
• Identity theft protection services (potential downstream demand if fraud prevention messaging increa
