Module G: Interactive FAQ – Your Tax Questions Answered
How does the Tax Calculator 201 handle self-employment taxes differently?
The calculator automatically applies the 15.3% self-employment tax (12.4% Social Security + 2.9% Medicare) to 92.35% of your net earnings. For incomes above $200,000, it adds the 0.9% Additional Medicare Tax. The system then allows you to deduct 50% of your self-employment tax from your income tax calculation.
What’s the difference between tax credits and tax deductions?
Tax Deductions reduce your taxable income (e.g., $1,000 deduction saves $220 if you’re in 22% bracket). Tax Credits directly reduce your tax bill dollar-for-dollar (e.g., $1,000 credit saves $1,000). The calculator automatically applies 47 different credits including EITC, Child Tax Credit, and Education Credits.
How does the calculator determine my filing status impact?
Your filing status affects:
- Standard deduction amounts (e.g., $29,200 joint vs $14,600 single)
- Tax bracket thresholds (joint filers get wider brackets)
- Eligibility for certain credits (e.g., EITC has different income limits)
- Capital gains tax rates (joint filers get higher 0% bracket)
The calculator runs parallel calculations for all statuses to identify the most advantageous option.
What income sources should I include in the calculator?
Include all taxable income:
- W-2 wages and salaries
- 1099-NEC freelance income
- Business income (Schedule C)
- Unemployment compensation
- Taxable interest and dividends
- Capital gains from investments
- Rental income (after expenses)
- Alimony received (for divorces finalized before 2019)
Exclude: Gifts, inheritances, life insurance proceeds, and municipal bond interest.
How does the calculator handle multi-state income?
For multi-state filers, the calculator:
- Allocates income based on state-specific rules
- Applies reciprocal agreements between states
- Calculates credits for taxes paid to other states
- Handles part-year residency scenarios
Note: For complex multi-state situations, consult a tax professional as state rules vary significantly.
