But! You get to pay taxes as if you made 800k in profit. So lucky you, you have zero dollars and now you get to pay 240,000 in tax (800k * 30%) to the government.
You're now 240k in the hole. Game over, no year two, three, or four.
This doesn't affect venture funded companies as badly because they have millions in funding and they can ride out the amortization. It does, however, affect bootstrappers trying to start a thing. Perhaps you could call them small, indie hackers?
If anything, HN should not be cheering this law as it doesn't affect large incumbents and those with millions in VC funding, but crushes the little guys.
