Worked Example — $100,000 Self-Employed Electrician (single filer)
SE Tax: $100,000 × 0.9235 × 15.3% = $14,130
Federal Income Tax: ≈ $12,000
Federal Total: $14,130 + $12,000 = $26,130
Federal Quarterly: $26,130 ÷ 4 ≈ $6,533
+ State estimate (varies, ex. ~$4,000): adds ~$1,000/qtr
All-in with state: ~$30,130 → ~$7,533 per quarter
