I just received a direct deposit of $675.83 from “Baker Tilly vant co entry” that I was not expecting. I am concerned this is a fraud or tax scam do you have any information about this?

It maybe a scam, see the following (you might want to talk to your bank)

What makes you think this is tax-related?

I also got money from Baker Tilly. I thought it was a fraud but after two hours of investigation understand that it was reimbursement from https://www.myflexdollars.com/.

I received an additional deposit from BT and it was accrued annual leave.
