Worked Example: A single filer earns $70,000 gross income with a $14,600 standard deduction. Taxable income is $70,000 - $14,600 = $55,400. Then, apply 2026 tax brackets: $11,600 at 10% ($1,160), then ($47,150 - $11,600) = $35,550 at 12% ($4,266), then ($55,400 - $47,150) = $8,250 at 22% ($1,815). Total estimated tax is $1,160 + $4,266 + $1,815 = $7,241.
