What Is an FMV Account? IRA Valuation, Reporting, and Penalties

An FMV account is a retirement account—almost always a self-directed IRA or a self-directed solo 401(k)—that holds assets without an automatic market price, so the account holder has to independently determine and report what those assets are worth at the end of each year. The custodian then reports that December 31 fair market value to the IRS on Form 5498, and the number drives everything downstream: required minimum distributions, the tax on a Roth conversion, and the paper trail the IRS uses to check your account against your tax return.¹

What Fair Market Value Means Here

Fair market value is the price a property would sell for on the open market between a willing buyer and a willing seller, with neither side under pressure to close and both having reasonable knowledge of the relevant facts.² The IRS treats an actual sale as a good indicator of value when it happens close to the valuation date, in an open market, and at arm’s length.

The definition excludes sentimental worth, fire-sale prices, and optimistic internal projections. For a brokerage account full of publicly traded stocks, the closing price on the valuation date satisfies the definition automatically and no one thinks twice about it. The whole concept of an “FMV account” exists because some retirement accounts hold assets that don’t trade on an exchange, and someone has to prove what those assets are worth.

Which Accounts and Assets Are Involved

Every IRA has to report a year-end value. In a conventional account holding only listed securities, the custodian pulls closing prices and files the numbers without your involvement. The accounts people call FMV accounts are the ones where that automated step breaks down: self-directed IRAs and self-directed solo 401(k) plans holding alternative investments. The custodian has no ticker symbol to look up, so the account holder is responsible for furnishing a defensible valuation each year.

The IRS tracks these alternative holdings through Form 5498’s box 15b, which uses category codes to flag the asset type:³

Code A — stock in a corporation not traded on an established market
Code B — short- or long-term debt not traded on an established market
Code C — ownership interest in an LLC or similar entity
Code D — real estate
Code E — partnership or trust interests not traded on an exchange
Code F — option contracts or similar products not on an established exchange
Code G — other assets without a readily available fair market value
Code H — more than two of the above asset types in one account

Precious metals also appear in FMV accounts, with an extra rule attached. The IRS generally treats metals and gems inside an IRA as collectibles, which triggers an immediate deemed distribution equal to the purchase cost. The exception covers certain U.S. Mint gold, silver, and platinum coins, and bullion that meets the minimum fineness standards for regulated futures contracts, but only if the bullion stays in the physical possession of the IRA trustee.⁴ Qualifying metals still need an annual FMV, typically based on the year-end spot price from a recognized commodities exchange.

How the Value Gets Reported

Form 5498 is the information return custodians file for every IRA they maintain. Box 5 shows the fair market value of all investments as of December 31.¹ When alternative assets are involved, box 15a breaks out their FMV and box 15b identifies the asset type using the codes above.

For the 2025 tax year, the custodian must send you a statement showing the December 31, 2025, value by February 2, 2026. The completed Form 5498 goes to the IRS by June 1, 2026.⁵ The February statement is the one you use for calculating a required minimum distribution early in the year, so your supporting documentation has to be in the custodian’s hands well before that.

The custodian files the form, but the custodian relies on you for the underlying valuation evidence on alternative assets. If your documentation is incomplete, the custodian can reject it and report the account with a zero or a prior-year figure, neither of which will hold up if the IRS cross-references your distributions against the balance on file.

Valuing Each Type of Asset

The right method depends on what the account holds.

Real Estate

The IRS recognizes three standard approaches for real property: a sales comparison method (analyzing recent sales of similar properties and adjusting for location, condition, and date), an income approach (capitalizing rental income), and a replacement-cost-less-depreciation approach.⁶ A formal appraisal from a qualified appraiser is required when you take an in-kind distribution of the property, convert a traditional IRA holding real estate to a Roth, or calculate a required minimum distribution. In years when none of those apply, some custodians accept a comparative market analysis or a property tax assessment, though a full appraisal is always the safer option.

Private Business Interests and LLCs

Valuing an ownership stake in a private company or LLC takes documentation from the entity itself: a current financial statement from the investment provider and signoff from a non-disqualified independent party such as a managing partner, CPA, or certified appraiser. If the entity holds multiple underlying assets—an LLC that owns both a bank account and rental property, for instance—you generally need supporting documentation for each one. A final Schedule K-1 only works if the business is dissolving. For private stock, recent arm’s-length purchase offers or a formula written into the shareholder agreement can serve as evidence.

Precious Metals

Qualifying gold, silver, platinum, and palladium bullion held by the IRA trustee can be valued using the December 31 spot price from a major commodities exchange. The custodian or depository usually provides a year-end statement showing the metal type, weight, and market value.

Who Qualifies as an Appraiser

When a formal appraisal is required, the IRS doesn’t accept just anyone’s opinion. A qualified appraiser has to hold an appraisal designation from a recognized professional organization (or meet equivalent education and experience requirements), regularly perform appraisals for compensation, and demonstrate verifiable experience valuing the specific type of property involved.⁷ The appraiser also cannot have been barred from practicing before the IRS at any point in the three years before the appraisal date.

The report itself has to include a detailed description of the property, its physical condition where relevant, the valuation method used, the comparable sales or data supporting the conclusion, and the effective date of the valuation. The appraiser signs it and includes a declaration acknowledging that penalties apply for substantial or gross misstatements.⁸

What It Costs

Fees vary widely with the asset, the complexity, and the market. Residential real estate appraisals for a single-family home generally run from a few hundred dollars up to roughly $1,500, with more for multi-family properties or homes in remote areas. Commercial real estate appraisals commonly land in the low thousands, and complex properties in major metros push higher. Business valuations have the widest range: a simple single-member LLC might come in under $1,000, while a formal valuation of a closely held company with real revenue can run well into five figures.

You pay these costs personally, not through the IRA. The account generally cannot cover the appraisal without risking a prohibited transaction if the appraiser is a disqualified person. Budget for the expense annually if your SDIRA holds assets that need independent valuation each year.

Why the FMV Number Matters

The December 31 value is not a reporting formality. It feeds two calculations that determine how much tax you owe.

Required Minimum Distributions

Your RMD for a given year is calculated by dividing the prior December 31 balance by a life expectancy factor from IRS tables.⁹ If the year-end value is wrong, the RMD is wrong. RMDs currently begin at age 73, with the threshold rising to 75 for individuals born in 1960 or later.¹⁰

If you don’t withdraw the full RMD by the deadline, the IRS imposes a 25% excise tax on the shortfall. That drops to 10% if you correct the mistake within two years.¹⁰ An inflated FMV means a larger RMD than you owe and a bigger tax bill. An understated FMV means a smaller RMD, which can leave you short of the required withdrawal and exposed to the excise tax. Either direction costs you money.

Roth Conversions

When you convert traditional IRA assets to a Roth, you owe income tax on the fair market value of whatever you convert. If your SDIRA holds a rental property and you convert it to a Roth, the taxable amount is the property’s FMV at the time of conversion. Undervaluing the property creates an underpayment that can trigger accuracy-related penalties. Overvaluing it means you voluntarily pay more tax than you owe, with no practical way to recover the overpayment after the fact.

Penalties for Inaccurate Valuations

The IRS has two tiers of accuracy-related penalties for valuation errors that produce a tax underpayment. A substantial valuation misstatement, where the claimed value is 150% or more of the correct amount, carries a penalty of 20% of the resulting underpayment. A gross valuation misstatement, where the claimed value hits 200% or more of the correct amount, doubles that penalty to 40%.¹¹ The penalties only apply when the underpayment attributable to the misstatement exceeds $5,000 ($10,000 for C corporations).

The thresholds matter in practice. If your SDIRA holds a rental property actually worth $200,000 and you report it at $320,000, that 160% overstatement crosses the substantial misstatement threshold. When a Roth conversion or RMD calculation is built on the inflated number and you underpay tax as a result, the 20% penalty attaches to the underpayment. The appraiser faces exposure too: the declaration they sign warns that penalties under Section 6695A may apply for misstatements based on their work.⁸

Prohibited Transactions and Losing the Account

Valuation problems can trigger something far worse than an accuracy penalty. If the IRA owner or a disqualified person (family members, fiduciaries, entities the owner controls) engages in a prohibited transaction connected to the account, the IRA stops being an IRA as of the first day of that year. The entire balance is treated as a taxable distribution at fair market value, and if the owner is under 59½, a 10% early distribution penalty applies on top of the income tax.¹²

A prohibited transaction that isn’t corrected also triggers an excise tax of 15% of the amount involved for each year it remains outstanding. If the transaction still isn’t corrected by the end of the taxable period, an additional tax of 100% of the amount involved applies.¹³

Valuation ties in because it can be what surfaces the underlying problem. An account holder who personally uses a property held in their SDIRA, or who pays themselves for managing an IRA-owned LLC, has already committed a prohibited transaction regardless of valuation. But a suspiciously low reported FMV (suggesting the owner has been skimming rental income) or a value inconsistent with distributions taken can be what draws the IRS in. Keeping the valuation clean and independent is the first line of defense against a disqualification that can wipe out years of tax-deferred growth in a single year.

Working With the Custodian on Timing

Treat the custodian’s FMV submission deadline as a hard date. Get your appraisals and supporting documentation together in the fourth quarter so the custodian has what it needs to file accurate numbers by the February statement and the June Form 5498. Work done with time to spare almost always produces a more reliable valuation than a January scramble, and a reliable valuation is the whole point of the exercise.
