BOISE, Idaho -

Rep. Clark Kauffman wants to take 2 percent of Idaho's total sales tax receipts -- $22 million now -- and direct it toward Idaho's estimated $262 million annual road and bridge funding shortfall.

The Filer Republican told the House Revenue and Taxation Committee Thursday the amount represents what's now generated from sales taxes on tires and automobile-related items.

Typically, Idaho doesn't dish out sales tax receipts toward roads, relying instead on registrations and fuel taxes.

But as lawmakers seek to raise roads cash without raising taxes, the sales tax has become a popular target.

Already this session, Rep. Joe Palmer of Meridian proposed a separate sales tax diversion.

Neither bill's prospects is clear, however.

That's because Gov. C.L. "Butch" Otter aims to delay highway-funding debate until after an ongoing study.
