California subtracts its $5,706 standard deduction and a $153 personal exemption credit for a single filer (tax year 2025); the credit shrinks by $6 for each $2,500 of income above $252,203 (California Franchise Tax Board — 2025 Form 540 Personal Income Tax Booklet, lines 18 and 32). Form 540 line 13 is federal adjusted gross income from Form 1040 line 11b, and Schedule CA carries the deductible part of self-employment tax on line 15 (Franchise Tax Board, 2025 California 540 booklet), so the deductible half of self-employment tax comes off California income too.
