bypass tax calculation in R12 similar to 11i

Example of data from the Legacy system:

line type ITEM             $100.00

Line Type TAX             $13.00

Tax rate US-ZERORATE (with rate defined in eBtax as zero%)

When I import above data I get the error indicating that the tax calculated by eBtax ($100 * zero=zero) is not equal to the Tax amount in the file ($13.00). I get the following error

ZX_IMP_TAX_RATE_AMT_MISPATCH                                     taxable basis for the imported tax
                                                                                                  line because the tax rate is 0 but
                                                                                                  the tax amount is not 0. Please
                                                                                                  change either the tax rate or the
                                                                                                  tax amount.

I have no issue in 11i as there is no such validation as in R12. I want to know how to bypass ebtax calculation for the imported invoices so that my tax remains what was passed ($13.00) by the Legacy system.
