On December 17, 2021, we notified the Commissioner, Wage and Investment Division, of our concern that the resources assigned to the RAIVS unit were not commensurate between the Kansas City and Ogden Tax Processing Centers. In our discussions, IRS management advised that taxpayer tax transcript requests had been previously transshipped from the Kansas City Tax Processing Center to the Austin Tax Processing Center with the last transshipment of work occurring in October 2021. On January 11, 2022, we notified the Director, Submission Processing, Wage and Investment Division, of the same concern noting that during our December 2021 walkthroughs, Kansas City management stated they have 70 full-time employees in the RAIVS/Income Verification Express Service’s unit. Whereas, Ogden management stated they have 183 full-time employees. As of December 10, 2021, the Kansas City RAIVS unit had over 751,000 unprocessed requests compared to a little more than 145,000 unprocessed requests in the Ogden RAIVS unit. We recommended that the IRS evaluate alternatives to address the volume of RAIVS inventory at the Kansas City Tax Processing Center. This should include an evaluation of the capacity to reallocate staffing at the Kansas City Tax Processing Center to assist the RAIVS unit, and/or realignment of work among the various Tax Processing Centers, i.e., transship inventory from Kansas City to Ogden.
