  • IRS Audit Notices SMore taxpayers are getting IRS notices this tax season than any recent year. By mid-March 2026, the IRS had already sent over 830,000 CP53E notices alone, and that's just one type. The reasons? New laws, staffing shortages, and AI-powered enforcement. Why the Notice Surge Three big factors are driving the jump in IRS letters: Executive Order 14247 stopped paper checks for federal payments (including tax refunds) as of September 30, 2025. If you filed your return without valid bank account info, you got a CP53E notice and your refund was frozen. You have 30 days to fix it via your IRS Online Account. The One Big Beautiful Bill Act (OBBBA) changed tax rules across the board - new deductions for overtime pay, tips, car loan interest, plus income-based phaseouts and new charitable contribution rules. The complexity means more taxpayers are filing incorrectly, which triggers automated notices. IRS staffing shortages are creating bottlenecks. Remaining staff are overloaded, and the agency is leaning harder on automated notices to prevent the statutory time limit for assessments from expiring. You're not getting flagged because you did something wrong - the IRS just doesn't have enough people to handle normal operations. AI Is Watching The IRS uses a Discriminant Function System (DIF) that scores every return against statistical norms for your income level and occupation. Returns that deviate too far get flagged. New in 2026: AI-powered cross-checks with third-party data (banks, payment platforms, payroll systems) and greater visibility into cryptocurrency and gig work. The 1099-NEC and 1099-MISC reporting thresholds jumped from $600 to $2,000 for 2026, but don't assume unreported income under that amount flies under the radar. Top Audit Triggers High income (over $400K) gets extra scrutiny, especially from self-employment, capital gains, or crypto. Excessive deductions relative to your income bracket raise red flags - a $75K earner claiming $30K in char
