The 2026 QBI Minimum: CPAs Must Explain the $400 Deduction

The 2026 QBI minimum deduction change is now law. Starting this calendar year, the OBBBA guarantees every taxpayer with at least $1,000 of qualified business income a minimum $400 deduction — adjusted for inflation going forward. This is not a complex calculation, but for the solo operator filing a Schedule C or the S-corp owner watching phaseout levels, it can be the difference between owing money and walking away clean. What most CPA firms miss is that the mechanics are easy; the client trust is hard. When a business owner hears about a new deduction from TikTok before they hear it from their CPA, the firm stops being an advisor and starts being data entry. This episode explains why the $400 QBI floor is the perfect case study for a bigger problem: most firms only communicate during filing season, and that timing is now a liability. We break down what changed, who it affects, and why the CPAs who explain it first build trust that converts into year-round advisory relationships.
