Let's say my business is growing, and each month, after bills are paid, I have leftover positive money (profit), if I buy more equipment in the following month, those are expenses and the profit is now used up for the business, and lets say I do this throughout the whole year (and I don't take any of the profits for myself, for example if I can pay my living expenses through other means), then I won't have much net profit by the end of the year, only more equipment, would I not even owe any taxes (because there is no net profit to show for in the year other than new equipment) ?
