Client Background
TaxNow is an industry-leading tax compliance platform that provides automated tools for businesses managing employee, vendor, and contractor filings. As client volumes grew, the company identified a need for a secure Taxpayer Identification Number (TIN) verification system to minimize IRS penalties and improve filing accuracy.
The Problem
Businesses using TaxNow needed to verify TINs in compliance with the IRS e-Services TIN Matching Program while managing growing volumes of submissions. Manual verification caused inefficiencies and delayed filings, increasing the likelihood of mismatched records and penalties.
Key challenges included:
Integrating directly with IRS verification systems for real-time data validation.
Automating bulk verification for thousands of records simultaneously.
Securing sensitive personal and financial information under GDPR and IRS Security Six standards.
Providing error visibility, audit logging, and real-time compliance reporting.
Ensuring system scalability during peak tax seasons without compromising performance.
TaxNow required a reliable and automated TIN verification framework that would seamlessly fit within its broader tax compliance ecosystem.
