A computer-implemented method of determining taxable basis amounts for a plurality of applicable taxes for a transaction line having a line amount includes steps of providing and evaluating a plurality of taxable basis formulae, one taxable basis formula for each of the plurality of applicable taxes that includes at least one of inclusive and exclusive taxes. Each of the list of applicable taxes may be compounded with one or more of applicable taxes, may be a surcharge of one or more of applicable taxes, may be neither compounded nor surcharged; and may be affected by a base rate modifier and/or additional charges or discounts allocated to the transaction line. The plurality of taxable basis formulae may be configured to derive an adjusted line amount such that the sum of the adjusted line amount and tax amounts of the inclusive taxes equals the line amount of the transaction. The plurality of taxable basis formulae may be stored in a database. One of the stored taxable basis formulae may then be selected and applied to a line amount of the transaction to compute the taxable basis of transaction, which may then be stored in the database. |
