Tried to "cheer" your response and couldn't... kept getting an "authentication failed" message... IMAGINE THAT!! 

Is this a possible workaround? Setup another deduction, name it Simple Roth, select "Simple IRA" as tax tracking type, but then uncheck all the taxes that get affected. Both Simple and Simple Roth report to box 12 on the W2 as code S. The only question then seems to be would it still reduce wages in box 1, even though you uncheck not to affect any taxes?

Thanks for joining this thread, jeremy77.
 

To properly identify if your proposed workaround works for your business, I'd recommend working with a tax professional.
