How Traditional 401(k) Reduces Your Taxes
1. Pre-Tax Contributions
Traditional 401(k) contributions are made before taxes. This reduces your taxable income dollar-for-dollar. If you earn $75,000 and contribute $10,000, your taxable income becomes $65,000.
2. Immediate Tax Savings
You save taxes at your marginal tax rate. In the 24% bracket, every $1,000 contributed saves you $240 in federal taxes immediately.
3. Tax-Deferred Growth
Your contributions grow tax-free until withdrawal. No taxes on dividends, interest, or capital gains inside the account.
4. Pay Taxes Later (Potentially Lower Rate)
You pay taxes when you withdraw in retirement. Many people are in a lower tax bracket in retirement, saving even more.
