§ Legislative Act Policy
Tax Enforcement Modernization
Current Status
Internal Revenue Code enforcement provisions (26 U.S.C. §§ 6201-6751). IRS Restructuring and Reform Act of 1998 established current organizational structure. Inflation Reduction Act of 2022 provided $80 billion over 10 years (subsequently reduced by Congressional rescissions).
IRS Commissioner administers enforcement. Treasury Inspector General for Tax Administration provides oversight. Taxpayer Advocate Service operates within IRS.
IRS budget approximately $12 billion annually with workforce of 80,000 (down from 117,000 in 1992)¹. Annual tax gap exceeds $600 billion (15% non-compliance rate)². Audit rates collapsed from 1.1% (2011) to 0.38% (2023)lowest in recorded history¹. Phone answer rates 29% with 28-minute average wait¹. Legacy IT systems from 1960s. Audit rate for millionaires below 1% while EITC audit rate remains elevated³.
Problem
$600+ billion annual tax gap represents revenue legally owed but not collected². Sophisticated tax avoidance faces minimal detection risk with audit rates at historic lows. IRS workforce decline means fewer agents pursuing larger economy. Technology modernization deferred for decades. Phone service virtually inaccessible for taxpayers seeking assistance.
Compliant taxpayers effectively subsidize non-compliant taxpayers. Low-income EITC claimants audited at higher rates than millionaires (enforcement inequity)³. Honest businesses compete against tax-evading competitors. Federal programs underfunded due to collection shortfall.
No sustained enforcement funding commitment. Taxpayer Advocate lacks binding authority over IRS. No independent audit selection oversight. No statutory audit equity requirements. IT modernization unfunded despite critical need.
IRS self-administers with limited external oversight. Taxpayer Advocate reports to IRS Commissioner (not independent). Audit selection algorithms lack external review. Enforcement intensity driven by budget cycles rather than compliance strategy.
Proposed Reform
Provide sustained IRS enforcement investment of $15 billion annually to close approximately 25% of tax gap, generating $150 billion in additional annual revenue5. Empower existing Taxpayer Advocate Service (TAS) with enhanced independence and binding authority. Mandate audit equity (high-income audited 10x EITC rate).
50% of enforcement funding ($7.5B) for personnel targeting taxpayers with income >$400K and business entities with gross receipts >$10M.
30% ($4.5B) for technology modernization including: replacement of all core tax processing systems operating on hardware or software more than 20 years old. Cloud-based infrastructure meeting FedRAMP High standards. Data analytics for compliance risk assessment. Electronic filing and processing systems. Secure APIs for information return submission, taxpayer account access, and third-party authorized data sharing. All systems meeting NIST Cybersecurity Framework standards.
15% ($2.25B) for taxpayer services (target: 85% answer rate, <5 minute wait). In-person assistance expansion. Online self-service portal development.
5% ($750M) for program oversight and coordination.
Mandatory audit equity ratios: audit coverage rates for taxpayers with AGI exceeding $1,000,000 must be not less than ten times the audit coverage rate for EITC claimants.
Commissioner shall publish quarterly reports on audit coverage by income decile, with separate reporting for EITC claimants.
GAO annual algorithmic audits of compliance with audit equity requirements4.
Tax Gap Closure Initiative with target of reducing gross tax gap by not less than 25%, with priorities: high-income individual non-compliance. Pass-through entity underreporting. International tax avoidance. Cryptocurrency and digital asset non-reporting. Cash-intensive business underreporting.
Annual Secretary reports to Congress on tax gap closure progress, including revenue recovered by category.
Annual Commissioner reports to Congress on technology modernization milestones.
Audit rate for EITC claimants shall not exceed 10% of audit rate for taxpayers with income exceeding $1,000,000.
Taxpayer Advocate Service (TAS) enhanced with structural independence, assuming binding authority over IRS.
TAS headed by National Taxpayer Advocate appointed by President with Senate confirmation for seven-year term, removable only for cause, operating independently of IRS Commissioner and Treasury Secretary.
TAS authorities include: issuing Binding Taxpayer Assistance Orders requiring IRS action or cessation of action causing significant hardship. Conducting binding arbitration for disputed assessments below $500,000 at taxpayer election. Reviewing and reporting annually to Congress on audit selection algorithms, enforcement equity, and systemic taxpayer rights issues. Maintaining regional offices in all 50 states.
Taxpayer Advocate Service budget independent of IRS Commissioner discretion. Functions enhanced with binding authority.
GAO annual algorithmic audits with published findings4.
Congressional reporting requirements.
What Changes
Before: IRS budget $12B with declining workforce (80,000 down from 117,000)¹. Tax gap $600B+ (15% non-compliance)². Audit rate 0.38% (historic low)¹. EITC claimants audited more than millionaires³. Taxpayer Advocate reports to IRS Commissioner. Phone answer rate 29% with 28-minute wait¹. 1960s legacy IT systems.
After: IRS budget $27B with restored enforcement capacity. Tax gap reduced 25% ($150B additional revenue)5. Audit equity mandated (high-income 10x EITC rate). Empowered TAS with binding authority. Phone answer rate 85% with <5 minute wait. Modern cloud-based IT infrastructure. GAO ITC algorithmic audits ensure fairness.

Change Log
- 2025-12-08 - Oversight Consolidation: Consolidated Independent Office of the Taxpayer Advocate (IOTA) to empowered Taxpayer Advocate Service (TAS) per oversight framework. Enhances existing TAS with structural independence (7-year term, for-cause removal, budget independence) and binding authority rather than creating new entity.
2025-12-07 - Template Standardization: Converted ROI section to required table format. Removed timeline language. Broke semicolon chains into separate sentences. Standardized spacing throughout document. Preserved all technical terms and legal citations.
2025-12-07 - Inline Citations: Added superscript citations; standardized References section.
2025-12-07 - Legislative Language Removal: Merged unique provisions into Proposed Reform; deleted Legislative Language section.
Revision (November 2025): Adjusted enforcement revenue projection from $280B (47% gap closure) to $150B (25% gap closure). Reasoning: Historical IRS enforcement initiatives achieved 10-20% gap closure; 25% represents ambitious but achievable target; conservative estimate improves credibility; 10:1 return on enforcement investment still exceptional.
Section 3: Added explicit audit equity prohibition and ratio requirement. Reasoning: Prior version set target without enforcement mechanism; explicit prohibition (EITC audit rate cannot exceed 10% of millionaire rate) creates legally binding requirement.
Section 5: Strengthened IOTA independence with binding arbitration authority for disputes below $500,000. Reasoning: Taxpayer Advocate currently advisory only; binding authority for smaller disputes provides meaningful recourse without burdening Tax Court; $500K threshold covers vast majority of individual taxpayer disputes.
Section 6: Added specific technology modernization requirements. Reasoning: Prior "modernization" language vague; specific requirements (legacy replacement, API infrastructure, FedRAMP High) create measurable milestones and accountability.
