This estimator is for educational purposes only and does not constitute tax advice. Federal figures use 2026 brackets and rates per IRS Rev. Proc. 2025-32 and the One Big Beautiful Bill Act (OBBBA). QBI thresholds per Section 4.26 of Rev. Proc. 2025-32. California figures use the 2025 FTB tax rate schedules (Schedule X/Y), which are the operative rates for 2026 estimated tax per the FTB 2026 Form 540-ES instructions, and standard deductions of $5,706 single/MFS and $11,412 MFJ/HOH as published by the FTB. Nevada and other no-tax states reflect $0 state income tax. SSTB phase-out is simplified — non-SSTB W-2 wage/property limitations are not calculated. Actual tax liability may differ.
