According to this recent post on Fishbowl, the answer is yes:

Hey, if you’re a low man or woman on the totem pole at PwC, didn’t mind traveling to a client site during a pandemic, and if you didn’t mind working during #PwCTakesABreak or whatever the hell PwC calls its two-week time-off period before busy season kills its employees, an extra $500 or more in your pocket seems like a pretty good deal.
Based on other responses in that thread, EY didn’t offer a similar financial incentive to its audit staff. Anyone at Deloitte, KPMG, Grant Thornton, BDO, or RSM get some extra cash for risking getting Rona while doing on-site inventory counts?

The CFTC’s action against PwC probably came as a result of a shocking CME Group announcement late Wednesday: “It now appears that the firm [MF Global] made … transfers of customer segregated funds in a manner that may have been designed to avoid detection.” These transfers, CME Group said, appeared to have taken place after its audit team showed up last week at MF Global to take a look and found everything to be in order. CME Group couldn’t have been hoodwinked like that if PwC had been doing its job all along. You can’t circumvent controls unless there are none or there are holes. It was PwC’s job to review controls and the adequacy of policies and procedures to support them. [
There was no additional compensation at KPMG.
No extra pay from BDO.
Can confirm the validity of this. An email was sent to staff firmwide.
I date a staffer from PwC. She is ugly but she counted 5 inventories, I flew her to them in my G4. She bought the steaks and the wine with her $500 per payments.
No incentive at Eide Bailly.
