The difference between a 22% and 12% marginal tax rate is $100 in taxes for every $1,000 of income shifted between them. Strategic income reduction isn't tax evasion — it's the intended design of the US tax code.
Strategy 1: Max your 401(k) contributions
In 2026, the 401(k) contribution limit is $23,500 ($31,000 if 50+). Every dollar contributed to a traditional 401(k) reduces your taxable income by exactly that amount. At a 22% marginal rate, contributing $23,500 saves $5,170 in taxes. The money isn't lost — it's working in your retirement account.
Strategy 2: HSA triple tax advantage
The HSA is the only account in the US tax code with three tax advantages simultaneously: pre-tax contributions, tax-free growth, tax-free withdrawals for medical expenses. Contribution limit in 2026: $4,300 (individual), $8,550 (family). At 22% rate, maxing individual HSA saves $946 in taxes.
Strategy 3: Traditional IRA (if deductible)
If you don't have a workplace retirement plan, or if your income is below the phase-out threshold, traditional IRA contributions are deductible. $7,000 contribution = $7,000 income reduction. At 22%, that's $1,540 in taxes.
Strategy 4: FSA for healthcare and dependent care
Healthcare FSA: $3,300 in 2026, pre-tax. Dependent care FSA: $5,000 per family. Combined: $8,300 of pre-tax dollars for healthcare and childcare. At 22% rate: $1,826 in tax savings.
Strategy 5: Self-employed deductions
If you have any self-employment income: home office deduction, vehicle business use, health insurance premiums (100% above-the-line), SEP-IRA or Solo 401(k) contributions (up to 25% of net SE income), and the QBI deduction (up to 20% of qualified business income).
Strategy 6: Tax-loss harvesting
If you have taxable investment accounts with unrealized losses: selling those positions locks in losses that offset capital gains. Up to $3,000 of net losses can also offset ordinary income annually. Remaining losses carry forward to future years indefinitely.
Strategy 7: Charitable giving optimization
Donating appreciated securities directly to charity avoids capital gains tax entirely and gets the full market value deduction. If you don't itemize, consider "bunching" — making 2 years of charitable donations in 1 year to exceed the standard deduction threshold.
| Strategy | Max annual tax reduction (22% bracket) |
|---|---|
| Max 401(k) | $5,170 |
| Max HSA (family) | $1,881 |
| Max IRA | $1,540 |
| Max FSAs (both) | $1,826 |
| Total potential | $10,417/year |
