Understanding the Concept
Tax optimization involves strategically using pre-tax contributions (401k, HSA, FSA), deductions, and credits to reduce your taxable income. Small adjustments to withholding can result in thousands saved annually.

- •Max HSA contributions ($4,150 single, $8,300 family) for triple tax advantage
- •Review W-4 withholdings annually to avoid large refunds or bills
- •Consider itemizing if deductions exceed standard deduction
- •Front-load retirement contributions if you expect a raise mid-year
- •Donate appreciated stock instead of cash for better tax treatment
