Yes, but as income at a more reasonable tax bracket. By default this kind of windfall is taxed the same as someone who makes that much money every year for years; all those shenanigans let you get taxed as someone making a smaller income for a longer time. Plus, over that longer time you can list a lot of dual-use purchases as untaxed business expenses.
