📚 Understanding Pre-Tax Deductions
Pre-tax deductions are taken from your gross pay before federal, state, and Social Security taxes are calculated. This lowers your taxable income, which can result in paying less in taxes overall. Common examples include contributions to traditional 401(k)s, health insurance premiums, and Flexible Spending Accounts (FSAs).

💰 Reduces Taxable Income: Lowering your taxable income means you pay less in taxes.
 🩺 Health Insurance Premiums: Many employer-sponsored health plans offer pre-tax deductions.
 👴 Retirement Savings: Contributions to traditional 401(k)s and similar retirement accounts are typically pre-tax.

🧾 Understanding Post-Tax Deductions
Post-tax deductions are taken from your net pay, after all applicable taxes have been withheld. These deductions do not reduce your taxable income. Common examples include Roth 401(k) contributions, charitable donations made through payroll deductions, and union dues.

📈 No Impact on Current Taxable Income: Post-tax deductions don't lower your current tax bill.
 ☀️ Roth 401(k) Contributions: While not tax-deductible now, qualified withdrawals in retirement are tax-free.
 🤝 Charitable Donations: Some employers offer the option to donate to charities through payroll deductions after taxes.
