The biggest legal levers on a W-2 paycheck: (1) max 401(k) ($23,000 in 2026 + $7,500 catch-up at 50+) — reduces both federal and state taxable in most states; (2) HSA ($4,150 single, $8,300 family) for triple-tax-advantaged savings; (3) FSA / commuter / dependent-care benefits; (4) state-specific 529 deductions in 30+ states. At $150,000 gross, maxing 401(k) alone saves roughly $8,400 in Illinois.
