Colorado's SB 26-134, which would have removed sales tax from interchange-fee calculations, was vetoed by Gov. Jared Polis. A similar law passed in Illinois. Had it taken effect, merchants would have paid interchange only on pre-tax transaction amounts, reducing their processing costs. Source: Digital Transactions.
