Multi-year profit/tax question
This is called "Net Operating Loss", and it is in fact applicable for individuals as well. You can, under certain circumstances, have NOL even as an individual. But it is far more common in the corporate world. What happens is that you can carry it back or forward, and get refund on taxes paid or adjust income for taxes to pay. In your example, you could carry the $75 NOL back and deduct it from the prior year earnings, reducing the taxable income from $100 to $25, getting $18.75 of the $25 paid as taxes - back. The link is for individual NOL, corporate rules are different, but the principle is the same.
