Kinda, for Q2 and Q3 you're expected to pay the full amount for the quarter about a month or so before it ends. So it's less the accounting method kinda and more I haven't been paid for a month that I already owe taxes for.

The periods aren't quite quarterly though. "Q2" ends on 5/31 and tax due 6/15, "Q3" ends on 8/31 and tax due 9/15. IIUC.

(I'm certainly not trying to argue that doing taxes 5 times a year isn't fucking onerous, though!)
