Why reinvesting in inventory doesn't reduce your tax the way you think

Buying more inventory reduces your future taxable income — but only when you sell it. Under the cash method of accounting, COGS is deducted in the year items are sold, not when purchased. Items still in your garage are an asset, not a deduction yet.
