Key Highlights from FY 2021 IRS IT Report
The FY 2021 report showcases impressive metrics and initiatives that demonstrate the IRS’s commitment to innovation and efficiency. Here’s a breakdown of the major goals and achievements:
Goal 1: Enhancing Customer Experience
The IRS processed 135.773 million individual tax returns, a 13.4% increase from the previous year, issuing $270.345 billion in refunds. Notable successes include the launch of the Tax Pro Account, expansions to the IRS Online Account (OLA) with features like balance details and digital notices, and the introduction of customer callback options for 16 toll-free lines, saving taxpayers 2.2 million hours. Tools like the “Get My Payment” app and Child Tax Credit Update Portal (CTCUP) supported the distribution of $46 billion in Child Tax Credit payments to families of 60 million children.
Goal 2: Advancing Applications and Services
Progress in modernizing core systems included migrating to a cloud-based Enterprise Case Management (ECM) platform for four programs and completing 70% of legacy code conversion in the Customer Account Data Engine 2 (CADE 2) program. This effort aims to retire the outdated Individual Master File (IMF) system. Additionally, the IRS launched a near real-time information returns data ingestion database and defined API standards for secure data access.
Goal 3: Leveraging Data and Analytics
The Return Review Program (RRP) detected $13 billion in pre-refund fraud, yielding a remarkable ROI of $139:$1. Enhancements included integrating external threat intelligence and behavioral analytics to combat insider threats, as well as end-to-end monitoring for six online tools.
Goal 4: Building Platforms and Infrastructure
The IRS expanded cloud adoption, with 64 systems using cloud services and the first IRS-built app migrated to the cloud. Aged hardware was reduced from 16% to 9.5%, and the Managed Infrastructure Data Service (MIDS) was adopted for scalable storage and computing.
Goal 5: Strengthening Cybersecurity
In a digital age fraught with threats, the IRS mitigated 1.4 billion unauthorized access attempts and blocked 140 million malicious emails annually. Key accomplishments include expanding Data at Rest Encryption (DARE), automating code reviews (85% faster), and securing five High Value Assets (HVAs) through network segmentation. Identity verification was modernized using ID.me for CTCUP.
Goal 6: Empowering the Workforce
To support a hybrid workplace, the IRS enhanced infrastructure for telework and opened a new call center in Puerto Rico. Over 2,000 employees received training in knowledge management, and six specialists were hired in emerging tech and cybersecurity.
Goal 7: Improving Technology Management
Eight new robotic process automations (RPAs) were developed, reducing compliance check times from 1 hour to 9 minutes and saving $7.5 million annually in nonfiler processing. The 2022 Target Enterprise Architecture was updated, and TFA provisions were implemented, including the appointment of a permanent CIO.
Goal 8: Fostering Innovation
Innovative tools like the Documentation Upload Tool were launched in just 20 days, enabling digital submissions and reducing paper backlogs. The first IRS Hackathon engaged 150 participants, producing prototypes for digitalization. Awards recognized excellence in RPA/AI and taxpayer service.
IRS IT Modernization Efforts and Initiatives
The report emphasizes the IRS’s multi-phase strategy for Information Returns (IR) modernization, aiming to e-file Forms 1099 by 2023. CADE 2 advancements have enabled faster responses to legislation, while cloud migrations and CI/CD pipelines have accelerated app deliveries. These efforts are part of a broader push toward a paperless, AI-driven tax administration system.
Cybersecurity and Data Analytics in Focus
Cybersecurity remains a cornerstone, with automated FISMA assessments and Zero Trust principles guiding future protections. Data analytics have been bolstered through real-time threat detection and expanded fraud models, ensuring the integrity of tax processes.
Looking Ahead: Future of IRS IT
The IRS plans to release Modernization Business Plan 2.0, expanding programs with American Rescue Plan funding. Focus areas include hybrid/multi-cloud ecosystems, AI/ML for anomaly detection, and a SaaS IT platform by FY 2023. These initiatives aim to achieve fully digital operations and enhanced taxpayer experiences.
