Tax planning involves legally arranging one's financial affairs to minimize tax liability, while complying with all applicable tax laws. Tax avoidance uses artificial or dubious methods to reduce taxes in a manner that defeats the intent of tax statutes. Tax evasion illegally avoids taxes through actions like knowingly making untrue statements or omitting required information. The line between tax planning and avoidance is thin, with avoidance including an element of mala fide intent or use of "colorable devices" to circumvent the spirit of tax laws.
