There are a ton of people here telling you their accountants telling you otherwise, mine included.

I think it would be much more helpful if you tried avoiding stating this as objective truth, and state more like your non-accountant opinion is that's how it works.

It essentially is, sorry. Having to amortize your R&D credits across five years is deadly to cash flow. The only EU country with a law like this is Belgium.

That also is an issue. US tax law is so damn complicated people spend time on understanding taxes instead of science.

Even the people who professionally do taxes (Accountants) can barely understand it and are debating it. It's utter insanity

You said elsewhere that you're not an accountant. What are your qualifications?

Just another misinformed internet commenter. You are free to draw your own conclusions.
