Taxable non-cash DBA do not withhold Fed, State and local

Hello,

We have a non-cash taxable benefit DBA setup for personal use of company car.  It gets processed quarterly on a regular paycycle as a OTO.

We want to not withhold Federal or State taxes (only Social Security and Medicare).  First we thought it was the PDBA Setup-Tax Exemption screen and but learned that makes it excludable wages  and would not report on their W2.

So is there a way to keep it in gross wages, but not withhold Fed, State and Local?  Processing it with the regular payroll, as we do need to withhold the SS/Medi.

Thanks

Kimberly
