Calculation Details:

The calculator estimates taxes using 2025 U.S. federal tax rules:

• Net Earnings: \\(\text{Net Earnings} = \text{Income} – \text{Expenses}\\)
• Self-Employment Tax: \\(\text{Taxable Earnings} = \text{Net Earnings} \times 0.9235\\), then \\(\text{SE Tax} = \text{Taxable Earnings} \times 0.153\\) (12.4% Social Security up to \$176,100 + 2.9% Medicare). Additional 0.9% Medicare tax if net earnings exceed \$200,000 (single) or \$250,000 (married filing jointly).
• SE Tax Deduction: \\(\text{Deduction} = \text{SE Tax} \div 2\\)
• Adjusted Gross Income (AGI): \\(\text{AGI} = \text{Net Earnings} – \text{SE Tax Deduction}\\)
• Taxable Income: \\(\text{Taxable Income} = \text{AGI} – \text{Standard Deduction}\\) (2025: Single: \$14,600, Married Filing Jointly: \$29,200, Head of Household: \$21,900, Married Filing Separately: \$14,600)
• Federal Income Tax: Apply 2025 tax brackets (e.g., Single: 10% on \$0–\$11,600, 12% on \$11,601–\$47,150, etc.)
• Total Tax: \\(\text{Total} = \text{SE Tax} + \text{Income Tax}\\)

Note: Estimates exclude state taxes, other income, or itemized deductions. Consult a tax professional for accuracy.
