Discount for Lack of Control: Why Your 409A Skips It and Your Gift Tax Return Can't
The discount for lack of control cuts minority stakes by double digits but rarely appears in a 409A. Why that's correct, and where it decides your tax bill.

# Discount for Lack of Control: Why Your 409A Skips It and Your Gift Tax Return Can't
Two valuations of the same company, a few months apart, can arrive with different discount sections and both be right. Say the first is a 409A supporting option grants and the second supports a gift of shares into a trust. The 409A applies one discount at the end. The gift tax valuation applies two, and the extra one takes another 15% or 20% off a number that already sits well below your last round price.
The instinct is to assume one of the appraisers overreached. Usually neither did. What separates the reports is the discount for lack of control, and whether the valuation had already accounted for control long before the report reached the word "discount."
That distinction moves real money on gift tax returns, buy-sell payouts, and ESOP transactions. It also explains the line item founders keep hunting for in their 409A and never finding.
What lack of control actually costs
Control of a company is worth something specific, and you can list what it buys. Whoever controls a private business sets officer compensation, decides whether to pay a dividend, picks the auditor, approves a sale, changes the strategy, and chooses the moment to look for a buyer. A shareholder who owns 15% of the same company gets none of that. They own a claim on cash flows that somebody else decides how to generate and when to distribute.
No rational buyer pays the same price for the second position. The discount for lack of control, shortened to DLOC and also called a minority interest discount, is the appraiser's estimate of how much less.
The size depends on what the minority holder can and can't do, which is a facts question rather than a table lookup. A 49% block with a board seat, veto rights over a sale, and a contractual right to financial statements is a very different asset from 2% of the same company with no information rights at all. State law matters too, along with the operating agreement and whether the controlling holder has a history of paying distributions or a history of paying themselves instead.
The rules name it out loud
Founders sometimes assume control discounts are an aggressive tax idea that appraisers bolt on to get a number down. The opposite is true. The government put them in the guidance.
The 409A regulations tell you to determine the fair market value of stock that isn't publicly traded by a reasonable application of a reasonable valuation method, then list the factors that method should weigh. Along with the value of tangible and intangible assets, the present value of anticipated future cash flows, and the market value of similar companies, [Treas. Reg. 1.409A-1(b)(5)(iv)(B)(1)](https://www.law.cornell.edu/cfr/text/26/1.409A-1) names "control premiums or discounts for lack of marketability" as factors to consider. The IRS wrote control into the same sentence as marketability in the rule that governs your strike price.
Go back further and it's already there. Rev. Rul. 59-60, 1959-1 C.B. 237 is still the foundation for valuing closely held stock, and the [IRS's own job aid for its valuation analysts](https://www.irs.gov/pub/irs-lbi/S%20Corporation%20Valuation%20Job%20Aid%20for%20IRS%20Valuation%20Professionals.pdf) reproduces its eight factors, the seventh being "sales of stock and the size of the block of stock to be valued." Block size is a valuation factor because a block that carries control is a different asset than one that doesn't.
Two discounts, two different problems
Lack of control and lack of marketability get blurred together constantly, including in reports that should know better. They answer different questions.
Lack of control asks what you can make the company do. Lack of marketability asks how fast you can get out. A 100% owner of a private business has complete control and still can't sell by Friday, so a controlling interest can carry a marketability discount with no control discount at all. A shareholder with 5% of a New York Stock Exchange company has no control whatsoever and can sell in seconds, so that position gets neither. The Tax Court drew this line decades ago in Estate of Andrews v. Commissioner, 79 T.C. 938 (1982), treating the minority discount and the marketability discount as separate adjustments measuring separate things.
Order matters, and it isn't a stylistic choice. The [IRS DLOM job aid](https://www.irs.gov/pub/irs-lbi/dlom.pdf) is direct about it: "DLOM is applied after the minority interest discount or control premium where such is appropriate to a valuation problem. DLOM should be determined on its own factors and not combined with other discounts."
Applied in sequence, the discounts multiply rather than add, and the difference is not trivial. Say a discounted cash flow analysis supports a control-basis equity value of $20 million for a distribution business, and the owner gifts a 20% block.
- Pro rata share of control value: $4,000,000
- Less a 15% discount for lack of control: $3,400,000
- Less a 25% discount for lack of marketability, applied to that result: $2,550,000
The combined haircut is 36.25%, not the 40% you get by adding 15 and 25. On a $4 million starting point that gap is $150,000 of taxable gift value, which is why the job aid's instruction not to combine discounts matters as much as the percentages themselves.
Why your 409A report doesn't show one
Here's the part that confuses founders looking for a DLOC line in their 409A. In most startup 409As, the control discount is already baked in before the discount section starts, so applying another one would double count.
Look at how the number gets built. A typical post-financing 409A uses an option pricing model backsolve: the appraiser takes the price your investors just paid for preferred stock, then solves for the total equity value that makes the model produce exactly that price. Our post on [OPM, PWERM, and the backsolve](https://www.409.ai/articles/409a-allocation-methods-opm-pwerm-backsolve) walks through the mechanics.
Now ask what that input actually is. Your Series A investor bought a non-controlling stake. They got protective provisions and a board seat, not the ability to sell the company or set your salary. The price they paid is a minority-interest price. Any equity value derived from it is a minority-basis value, and the common stock allocated out of it inherits that basis. The only thing left to adjust for is liquidity, which is why a well-built 409A ends with a [discount for lack of marketability](https://www.409.ai/articles/discount-lack-marketability-dlom-409a-valuation) and nothing else.
The same logic explains the [market approach](https://www.409.ai/articles/market-approach-409a-valuation) when it leans on guideline public companies. Public share prices are minority prices, because an investor buying 100 shares of a listed company isn't buying control either. Multiples drawn from those prices carry a minority basis with them.
Flip to the [income approach](https://www.409.ai/articles/income-approach-409a-valuation) and the basis flips too. A discounted cash flow built on management's projections values the enterprise as a whole, on the assumption that whoever holds it can execute that plan, adjust the cost structure, and redirect the cash. That is a control-basis value. An appraiser who runs a DCF and then allocates straight to a minority common block without any control adjustment has skipped a step.
So the question to ask about a report isn't "where's the control discount." It's "what basis is the value on, and does the discount section match it?"
Where the control discount does the work
Outside the 409A world, this adjustment is usually the main event.
Gift and estate tax. Transfers of minority blocks in private companies are where DLOC gets litigated hardest, because it directly reduces taxable value. The IRS conceded the central point in Rev. Rul. 93-12, 1993-1 C.B. 202, which revoked Rev. Rul. 81-253 and held that it won't automatically aggregate family members' voting power to treat a transferred minority block as part of a controlling interest. In the ruling's own facts, a sole owner gave away five separate 20% blocks to five children, and each one was valued as a minority interest even though the family collectively still owned the whole company. An IRS Chief Counsel memorandum puts the operating rule plainly: [each gift is valued separately](https://www.irs.gov/pub/irs-wd/0143004.pdf) and isn't aggregated with other gifts made at the same time. If you're [gifting startup equity against the current exemption](https://www.409.ai/articles/gifting-startup-equity-2026-estate-tax-exemption), this is the mechanism that makes the transfer efficient.
Buy-sell agreements and shareholder exits. Whether a departing minority holder gets a pro rata slice of enterprise value or a discounted minority value is a drafting question that most agreements answer badly or not at all. The gap between those two numbers is the whole fight. Related traps show up in the [treatment of company-owned life insurance after Connelly](https://www.409.ai/articles/buy-sell-agreement-valuation-connelly-life-insurance).
Owner-operated businesses. An FMV valuation of a family company for a loan, a divorce, or an ownership change almost always confronts control, and often [tax affecting](https://www.409.ai/articles/tax-affecting-pass-through-entity-s-corp-valuation) at the same time. Those two assumptions together can move a small-business number by 40% or more.
ESOPs, in reverse. Here the argument is usually about a control premium rather than a discount, since the plan may be buying a controlling block. Whether the appraisal can reflect control depends on whether the plan genuinely gets control it can use, which is one strand of the [adequate consideration standard](https://www.409.ai/articles/esop-valuation-adequate-consideration-2026) behind every annual appraisal.
How an oversized control discount gets attacked
The IRS doesn't dispute that DLOC exists. It disputes the number, and it has a favorite line of attack: find a public market where investors buy non-controlling claims on a pool of assets and see what they actually pay.
The Chief Counsel memorandum above makes the comparison explicit for entities holding liquid assets, pointing to closed-end funds, whose investors own a share of a managed pool with no say over the assets. Those funds, the memo notes, generally trade at discounts to net asset value of 4 to 12 percent, "a discount which is deemed sufficient by the public markets to reflect the disadvantages of a minority interest." That benchmark is aimed at family entities holding cash and marketable securities, not at operating companies with real business risk, and the memo separately acknowledges a marketability discount may still be owed. But it shows the shape of the argument. If your appraiser claims 35% for lack of control on a company whose assets are a brokerage account, they need a reason that survives that comparison.
The defensible reports do three things. They say what basis the value is on before discounting. They tie the discount size to the specific rights the subject block does and doesn't have, quoting the operating agreement rather than citing a range from a textbook. And they keep the two discounts separate, sized on their own evidence, applied in sequence.
What to check in your own report
Open the valuation you're holding and find the page where the appraiser goes from total equity value to the value of the specific interest. Then answer two questions. What basis did the concluded value start on, control or minority? And does every discount after that point correspond to something the value hadn't already captured?
If it's a post-financing 409A and there's no control discount, that's almost certainly correct. If it's a DCF-driven valuation of a minority block in an operating company and there's no control discount, ask why. If there is one, ask what rights the block is missing and where the percentage came from. An appraiser who can answer in terms of your cap table and your operating agreement has done the work. One who answers with a range from a study has given you a number that a reviewing agent will price-test on their own terms.
