No it has not been resolved.

I have been telling employees up front that federal taxes will not be withheld under this new form.

They should go to irs.gov and use the calculator.  Also contact the IRS to verify the information.

I find that the calculator is not giving correct information either, but at least in the end when an employee complains about no federal tax withholding, I can say I only entered the information the IRS gave you, take it up with them.

Amounts are taken out on larger wages, as i entered different numbers to test quickbooks, 

but not on my minimum wage employees.
