Every dollar you put into a 401(k) reduces your taxable income โ which means you pay less in federal and state taxes right now, not just at retirement.
If your employer offers health insurance, paying your premium through payroll deductions is pre-tax โ meaning you avoid federal, state, and FICA taxes on that money.
An HSA (Health Savings Account) is triple tax-advantaged: contributions are pre-tax, growth is tax-free, and withdrawals for medical costs are tax-free. An FSA works similarly but the funds don't roll over.
The W-4 tells your employer how much tax to withhold. If you claim too many allowances, you'll owe in April. Too few, and you overpay all year (giving the government a free loan).
Once you know your take-home pay, try this classic budgeting framework to make every dollar count:
The 2024 standard deduction is $14,600 for single filers. If your total income for the year is under that, you owe zero federal income tax and will get a full refund of any withholding!
Compound interest means your money earns returns on its returns. Starting at 18 vs 28 can literally double your retirement savings with the same monthly contribution.
