Understanding Your Tax Burden

Most Americans significantly overestimate their federal tax rate because they confuse their marginal rate (the rate on their top dollar of income) with their effective rate (the average rate on all income). In the U.S. progressive tax system, only the income above each bracket threshold is taxed at the higher rate — not all your income. A $75,000 single filer in the 22% bracket typically has an effective rate closer to 14–15%.

The most effective legal strategy for reducing your tax bill is maximizing pre-tax retirement contributions. Every dollar contributed to a traditional 401(k) or IRA reduces your federal taxable income by exactly that amount, saving you your marginal tax rate on each dollar. At a 22% marginal rate, a $10,000 401(k) contribution saves $2,200 in federal taxes — an immediate return before any investment growth.
