Shoppers buying groceries beginning Monday can expect a slightly lower sales tax, but they shouldn't expect all the food and drinks they buy to be taxed at the same rate.

That's because when lawmakers agreed to cut the state's portion of the sales tax on unprepared food from 4.75 percent to 2.75 percent, they also had to define what unprepared food meant. That resulted in some seemingly odd distinctions.

A soft drink in a bottle is taxed at the new, lower rate. A soft drink from a fountain machine doesn't get the discount.

The difference? The fountain machine soda is served with "utensils" — a cup, lid and straw.

The same goes for deli items such as sandwiches and salads. If it comes with a fork, expect to pay the higher sales tax.

"It seems stupid. It seems kind of random, but it's not like it makes that much of a difference, really. I probably won't even notice it," said Emily Martinez, 19, who was going grocery shopping at a downtown Albertsons.

And while hot dogs and sandwiches sold at convenience stores will be taxed at the higher rate, bargain hunters can save a few cents by buying the ingredients and making sandwiches themselves.

Sometimes, a napkin makes the difference in price. Bagels and doughnuts sold with a napkin don't get the discount, but those in a box do.

Even vending machines aren't uniform in their tax rules.

A bag of chips, chewing gum and soda will be taxed at the lower rate. A premixed cup of hot chocolate, sandwich or a slice of pizza are taxed at the full rate.

That's because each of those have more than one ingredient.

For people like Derrick Jones, who is unemployed, taxing any food is maddening.

"Why are they going to tax me? I can't afford it. They're crooks. That's what they is — crooks," Jones said while waiting for a bus.

In 2006, Gov. Jon Huntsman Jr. sought to completely remove the state's portion of the sales tax on food. He had the support of the House, but Senate leaders considered it bad tax policy. So they compromised on reducing the rate.

In 2007, Huntsman isn't planning on touching the sales tax on food, instead focusing on reducing income taxes. But House Speaker Greg Curtis, R-Sandy, has said he'd like to see the tax removed. Once again, Senate leadership has said it's opposed to the measure.

Rep. Craig Frank, R-Pleasant Grove, said while House Republicans haven't decided how they would allocate $300 million in tax cuts they're proposing, it's likely removing the sales tax on food will be part of the mix.

One obstacle — reprogramming grocery stores' computers to identify items that should be taxed differently — is already taken care of, he said.
