By that size they should really have it figured out.
I kinda expect things to not be completely perfect, because there are 400 something paychecks going through one person. But it's way more screwed than it should be. It took 8 months to figure out how to get my bonus checks withheld correctly for taxes. Kept running it through the monthly or quarterly table, but since the checks were smaller than my normal biweekly check, hardly anything was coming out, while the withholding on my regular checks were somewhat engineered on the assumption that the bonus checks would be withheld at the federal guideline of 22% and the top state tax bracket. I ended up having to pay in like $4k, but fortunately I was expecting it so I was squirrelling away the money they weren't withholding. The only way they got it figured was to use the accounts payable system instead of payroll, but that means it has to be a paper check instead of direct deposit. They mail it to me monthly, but last month I was in town so I picked it up. It only had one signature on it and none of the people who could provide the second signature were in the office, so I had to give it back.
