payment of all taxes, interest and penalties related to any assessment by a taxing authority as contemplated by Section 16.6 to the extent that Supplier fails to accurately and timely invoice Bank of America for such taxes and remit such taxes directly to the applicable taxing authority. In the event that a taxing authority performs a sample and projection audit on Bank of America, then Supplier shall be responsible for the payment of all projected tax amounts including all interest and penalties on any projected taxes assessed resulting from taxing errors identified by such taxing authority on Supplier's Invoices, provided however, that Supplier shall receive timely notice that such invoice is included In a tax authority's audit and Supplier has the right to produce documentation to support that the tax was satisfied. In the event Supplier voluntarily registers to collect sales tax at some future date, and wishes to remit historical taxes Supplier deems due, Bank of America will only be responsible for the taxes due for the time period that Bank of America is statutorily obligated to the tax authorities in each state. 16.9 Supplier shall fully cooperate with Bank of America's efforts to identify taxable and nontaxable portions of amounts payable pursuant to this Agreement (including segregation of such portions on invoices) and to obtain refunds of taxes paid, where appropriate. Bank of America may furnish Supplier with certificates or other evidence supporting applicable exemptions from sales, use or excise taxation. If Bank of America pays or reimburses Supplier under this Section, Supplier hereby assigns and transfers to Bank of America all of its right, title and interest in and to any refund for taxes paid. Any claim for refund of taxes against the assessing authority may be made in the name of Bank of America or Supplier,
