Sales Tax on Gold and Silver in Iowa

Iowa does not charge sales tax on the sale of coins, currency or bullion. The exemption is written into Iowa Code 423.3(91), so the sales price of qualifying metal is not taxed at the point of sale.

What qualifies for the exemption

The statute covers three categories:

• Bullion — bars, ingots or commemorative medallions of gold, silver, platinum, palladium, or a combination of these metals, where the value depends on the metal’s content rather than its form.
• Coins — a coin made of gold, silver, another metal, or paper that is or has been used as legal tender.
• Currency — paper or metal money that is or has been used as legal tender.

Because the definition turns on metal content and legal-tender status, the exemption is not limited to a particular weight, fineness or brand. Iowa’s statute sets no dollar threshold and no purity percentage.

What the rule does not address

The statute does not set a minimum purchase amount, so a single small coin and a large bar are treated the same way under the exemption. It also does not describe a separate test for jewelry or for fabricated items whose value comes from craftsmanship rather than metal content; the definition of bullion is tied to value based on content, not form. Iowa’s statute likewise does not state a rule for local sales taxes on these sales.

The official source

The controlling text is Iowa Code 423.3(91). The exemption reads: “The sales price from the sale of coins, currency, or bullion.” The same section defines bullion as “bars, ingots, or commemorative medallions of gold, silver, platinum, palladium, or a combination of these where the value of the metal depends on its content and not the form.”

This rule was checked in October 2026. Tax law changes with new legislation, so confirm the current text with the Iowa Department of Revenue or the Legislature before a large purchase. For how precious metals are treated at the federal level, see sales tax on gold.

What buyers commonly get wrong

A frequent mistake is assuming the exemption applies only above a certain purchase size. Iowa’s statute contains no dollar threshold, so size is not the test.

Another is treating the exemption as limited to gold and silver. The definition of bullion also names platinum and palladium, and it covers combinations of those metals.

A third is assuming a purity or fineness standard must be met. The statute states no purity percentage; the question is whether the value depends on metal content rather than form.

A fourth is reading the exemption as covering every object made of precious metal. The definition is built around bullion, coins and currency, and it does not set out a separate rule for jewelry or other fabricated pieces.

Finally, buyers sometimes assume the exemption settles every tax question about a purchase. It does not address local sales taxes, and it says nothing about income tax, capital gains or reporting obligations that may apply later.

Rules of this kind can change when the legislature acts, and the treatment of a specific item can depend on details the statute does not spell out. A tax professional or your own preparer can review your particular situation.
