IRS Publication 2104-B – In the complex world of U.S. taxation, IRS Publication 2104-B stands out as a critical resource for understanding taxpayer challenges and IRS operational hurdles. This document, part of the National Taxpayer Advocate Annual Report to Congress, focuses on in-depth research studies that highlight systemic issues affecting millions of Americans. Released in 2023 (with a revision date of January 2024), it delves into topics like IRS online account limitations, improper tax credit bans, and identity verification failures leading to frozen refunds. Whether you’re a taxpayer seeking better digital services or a professional navigating credit claims, this guide breaks down the key findings, recommendations, and data to help you stay informed.
What Is IRS Publication 2104-B?
IRS Publication 2104-B, titled “National Taxpayer Advocate Annual Report to Congress: Research Reports,” is a specialized volume within the broader Annual Report series. Produced by the Taxpayer Advocate Service (TAS), an independent organization within the IRS, it presents empirical research on pressing taxpayer issues. The 2023 edition emphasizes three main studies, drawing from interviews, case reviews, and comparative analyses of domestic and international tax systems.
The report underscores the TAS’s role in advocating for taxpayer rights, including the right to quality service, privacy, and a fair tax system. With IRS handling over 93 million phone calls and only 11% of filers using online accounts in FY 2023, it calls for modernization to reduce burdens and improve efficiency. This publication is essential reading for anyone interested in IRS reforms, tax policy, or common pitfalls in filing.
Research Study 1: Taxpayer Opinions on IRS Online Accounts and Global Comparisons
One of the core focuses of IRS Publication 2104-B is enhancing digital access to tax services. This study explores U.S. taxpayers’ preferences for IRS individual online accounts while reviewing features offered to businesses and tax professionals by state and foreign tax authorities.
Objectives and Methodology
The objective was to identify desired features, security concerns, and gaps in current IRS offerings. Researchers conducted 48 in-depth interviews with diverse taxpayers (including those with low tech familiarity) from August to November 2023. Additionally, they reviewed websites from 48 U.S. states, the District of Columbia, Puerto Rico, and three countries (Canada, Australia, UK), assessing account creation, filing, payments, and more.
Key Findings
Taxpayers appreciate online accounts for convenience but express concerns over security and privacy. Only 16.8 million unique users accessed IRS accounts in FY 2023, representing about 11% of 160 million filers. Compared to states (94% offering business accounts) and foreign systems, the IRS lags in features like interactive tools, mobile apps, and third-party access. For instance, 46% of states allow online filing for businesses, while the IRS limits accounts for sole proprietors.
Notable data includes:
- 64.4 million IRS account sessions in FY 2023.
- 86% of taxpayers want email contact options, per the 2022 Comprehensive Taxpayer Attitude Survey.
- Tables like Figure 2.1.3 show authentication methods, with 94% of states using ID info.
Recommendations
To address these gaps, the report suggests adding tutorial videos, live chat, personalized tax planning tools, and red-flag notifications. These changes could reduce IRS call volumes (93 million in FY 2023) and align with global e-administration trends.
Research Study 2: Two-Year Bans on Earned Income Tax Credit (EITC), Additional Child Tax Credit (ACTC), and American Opportunity Tax Credit (AOTC)
Tax credit bans can devastate low-income families, and this study in IRS Publication 2104-B examines the IRS’s compliance with procedures for imposing two-year bans due to reckless or intentional disregard.
Objectives and Methodology
Aimed at evaluating procedural adherence and taxpayer impacts, the study reviewed a random sample of 352 cases from 3,153 bans imposed in FY 2022 and early FY 2023. Data included managerial approvals, explanations on Forms 886-A, and prior disallowances, with a 95% confidence level.
Key Findings
Bans surged 47% in FY 2023, with ACTC bans up 805% to 2,481. Median AGI for affected taxpayers was $18,501, and the median banned EITC was $3,619. Alarmingly, 76% of cases lacked required managerial approval, and 81% of Forms 886-A were inadequate. In 30% of cases, no ban was imposed despite prior same-reason disallowances, showing inconsistencies.
Key statistics:
- 46% of cases had no taxpayer response or undeliverable mail.
- Figure 2.2.1 compares bans: EITC down 11%, ACTC up dramatically.
- 54% of notices provided insufficient explanations.
Recommendations
Reforms include requiring same-reason prior audits (limited to under three years old), better explanations, and managerial reviews to prevent arbitrary bans and protect vulnerable taxpayers.
Research Study 3: Potentially Legitimate Taxpayers Denied 2020 Refunds Due to Identity Verification Failures
Identity theft remains a top concern, and this study addresses taxpayers who lost TY 2020 refunds after failing to respond to IRS verification letters.
Objectives and Methodology
The goal was to assess response rates to TAS outreach and the effectiveness of single-letter notifications. TAS mailed letters to a stratified sample of ~4,000 from ~88,000 potentially legitimate taxpayers, tracking authentication and refund issuance.
Key Findings
Over 3.7 million TY 2020 returns were flagged for identity theft, with >60% false positives. Average authentication time was 20 months for 19,261 cases reversed post-archive. Median refund was $1,915, with many claiming EITC. Low service levels on the Taxpayer Protection Program (TPP) line (31% in FY 2023) exacerbated delays.
Data highlights:
- Frozen refunds totaled >$500 million (median ~$1,800).
- Figure 2.3.1 details post-archive cases.
Recommendations
Implied actions include sending multiple notices, improving filters, and enhancing service to ensure legitimate refunds are released promptly.
