Understanding Tax Calculations
Your effective tax rate is the percentage of your total income paid in taxes. It's typically lower than your marginal rate because of progressive tax brackets.
Your marginal tax rate is the rate you pay on your last dollar of income. This is the rate that applies to additional income you might earn.
Deductions reduce your taxable income. You can choose between the standard deduction or itemizing deductions if they exceed the standard amount.
Tax Planning Tips
Maximize deductions by tracking charitable donations, mortgage interest, and state/local taxes paid.
Contribute to retirement accounts like 401(k) or IRA to reduce current year taxable income.
Adjust your withholding to avoid large refunds or tax bills. Aim to break even for optimal cash flow.
