Tax optimization strategy is the legal art of structuring business and personal finances to minimize tax liability within the law. It includes choosing the right business entity (C-Corp, S-Corp, LLC, Solo), timing income and deductions, selecting favorable jurisdictions, and leveraging tax-advantaged accounts and investments. Tax optimization is not tax evasion (illegal) but legitimate use of tax code provisions to reduce burden. It's practiced by entrepreneurs, corporate CFOs, and financial advisors to increase take-home income and business profitability.
