Common Mistakes to Avoid
⚠️
All income taxed at marginal rate
Tax brackets are marginal — only income within each range is taxed at that rate.
⚠️
Gross vs taxable income
This needs taxable income (gross minus standard deduction). Single standard deduction: $14,600 in 2024.
⚠️
Forgetting state and FICA
Add state tax (0–13%) and FICA (7.65%) for the full picture.
