look up any word, like bukkake:
 
1.
additional charges paid for goods or services purchased by a white person at a minority-run place of business

exact amounts and percentages are at the discretion of the seller, but are often small enough that the buyer doesn't realize the addition until after the transaction has been completed
on my way back from the seven eleven on MLK blvd, i realized my pack of smokes and case of bud cost more than it did from the one i usually go to on first st. must have been my white tax.
