Starting Jan. 1, 2012, Form 1099s will become a means of reporting to the Internal Revenue Service the purchases of all goods and services by small businesses and self-employed people that exceed $600 during a calendar year. Precious metals such as coins and bullion fall into this category and coin dealers have been among those most rankled by the change.

This provision, intended to mine what the IRS deems a vast reservoir of uncollected income tax, was included in the health care legislation ostensibly as a way to pay for it. The tax code tweak is expected to raise $17 billion over the next 10 years, according to the Joint Committee on Taxation.

Taking an early and vociferous role in opposing the measure is the precious metal and coin industry, according to Diane Piret, industry affairs director for the Industry Council for Tangible Assets. The ICTA, based in Severna Park, Md., is a trade association representing an estimated 5,000 coin and bullion dealers in the United States.

"Coin dealers not only buy for their inventory from other dealers, but also with great frequency from the public," Piret said. "Most other types of businesses will have a limited number of suppliers from which they buy their goods and products for resale."

So every time a member of the public sells more than $600 worth of gold to a dealer, Piret said, the transaction will have to be reported to the government by the buyer.

Pat Heller, who owns Liberty Coin Service in Lansing, Mich., deals with around 1,000 customers every week. Many are individuals looking to protect wealth in an uncertain economy, he said, while others are dealers like him.

With spot market prices for gold at nearly $1,200 an ounce, Heller estimates that he'll be filling out between 10,000 and 20,000 tax forms per year after the new law takes effect.

"I'll have to hire two full-time people just to track all this stuff, which cuts into my profitability," he said.

An issue that combines gold coins, the Obama health care law and the IRS is bound to stir passions. Indeed, trading in gold coins and bars has surged since the financial crisis unfolded and Obama took office, metal dealers said.

The buying of actual gold, as opposed to futures or options tied to the price of gold, has been a particularly popular trend among Tea Party supporters and others who are fearful of Obama's economic policies, gold industry members such as Heller and Piret said
