Earlier quoted context omitted.
I'm not an accountant, but as I understand it, you don't pay taxes on profits, but on revenue. So previously, some 20% of all revenue would be owned as corporate income tax, and startups would deduct it all as they're spending much more on R&D than they owe in corporate income tax. But with this tax change, the deduction would be much lower (80% lower IIUC).
No, you pay taxes on profits. What this does is reduce your upfront deduction.
Simplified 2021 example before 174:
100k Revenue
100k Software Dev Costs
No profit or tax
Simplified 2022 example after 174: 100k Revenue
100k Software Dev Costs
90k "profit"
18.9k taxes
Above example is year one of suddenly having these taxes, because if your software costs are the same or lower over time it gets easier. It's just extremely painful for smaller and especially fast growing companies like startups without a lot of cash, especially when interest rates are so high.Accountants: If I am wrong about the above, please correct me
