💡 Understanding Tax Withholding

📊

Marginal vs Effective Rate

Your marginal rate is the tax on your last dollar earned. Your effective rate is total tax divided by total income.

💰

Reduce Taxable Income

Pension, retirement, and eligible deductions may reduce taxable income.

📋

Check Your Withholding

Too much withholding may create a refund, while too little may create a tax bill.
