409A Valuation for an LLC or S-Corp: When You Actually Need One

Does an LLC Need a 409A Valuation?

A 409A valuation for an LLC isn’t automatically required, because Section 409A reaches the award you granted, not the entity wrapper around it. Nothing in the rule turns on entity form, so an LLC or an S-corp can sit squarely inside Section 409A. What an LLC doesn’t get is the stock-valuation safe harbor people mean when they say “409A valuation.”

So the useful question isn’t which entity you are.

It’s which award you signed.

The textual chain almost nobody walks runs in four steps.

1. The definition has no entity limit. Treas. Reg. 1.409A-1(a)(1) defines a nonqualified deferred compensation plan as “any plan … that provides for the deferral of compensation.” No corporation appears in that sentence.
2. The exception is corporate-only. The stock-rights exception works only on “service recipient stock,” which 1.409A-1(b)(5)(iii)(A) defines as common stock of “a corporation that is an eligible issuer of service recipient stock.” An LLC unit isn’t stock of a corporation, so the presumption framework at (b)(5)(iv)(B) never reaches it literally.
3. There’s a door for everyone else. Subdivision (b)(5)(iii)(D), titled “Other entities,” lets a non-corporate interest count as service recipient stock “to the extent designated by the Commissioner in revenue procedures, notices, or other guidance published in the Internal Revenue Bulletin.”
4. The Commissioner walked through it. Notice 2005-1, Q&A-7 is that guidance, and the T.D. 9321 preamble confirms the final regulations “do not address such arrangements.”

A pass-through therefore uses the stock principles by analogy, not by text. Our essential guide to 409A valuations and our explainer on the IRS rules behind 409A cover the corporate baseline those rules were written for.

The familiar 12-month figure isn’t a general rule either. It’s a condition inside one safe harbor, 1.409A-1(b)(5)(iv)(B)(2)(i), which wants the appraisal dated “no more than 12 months before” the grant. For a pass-through that’s a sensible operating cadence rather than a deadline, plus a refresh on anything that moves value, as our guide to 409A refresh triggers lays out.

Which Pass-Through Awards Section 409A Reaches

Section 409A reaches options, appreciation rights, phantom units, and restricted units in a pass-through on the same terms it reaches them in a corporation. Capital interests and qualifying profits interests sit outside it, for different reasons. Go award by award, because scope settles at the award level.

Options and appreciation rights on units or S-corp stock

Both are in scope, and both are exempt only if they’re priced right. Treas. Reg. 1.409A-1(b)(5)(i)(A)(1) exempts an option only where the exercise price “may never be less than the fair market value” of the underlying stock on the grant date, with a fixed share count. The appreciation-right exception at (b)(5)(i)(B)(1) caps the payout at the excess of fair market value at exercise over an amount specified on or before the grant date. Set the strike or base amount below grant-date value and the exception evaporates. What follows is income inclusion, an additional 20 percent tax under IRC 409A(a)(1)(B)(i)(II), and premium interest at the underpayment rate plus one percentage point. For an option on LLC units, that exception arrives through the Notice 2005-1 bridge rather than the literal text. Our 409A safe harbor explainer covers the corporate version.

Phantom units, capital interests, and restricted units

Phantom units are in scope by design. A phantom unit is an unfunded promise to pay cash measured by unit value later, the textbook shape of a legally binding right to compensation payable in a future year. The usual escape is the short-term deferral rule at Treas. Reg. 1.409A-1(b)(4), which requires payment by the 15th day of the third month after the year the substantial risk of forfeiture lapses. Most plans pay on a sale or a fixed date years out, so they don’t qualify and have to comply instead. Design sits in our phantom stock post, not here.

Capital interests are a different animal. One gives the holder a share of liquidation proceeds on a hypothetical sale and liquidation at fair market value, so granting it for services is a property transfer under IRC 83(a), and Treas. Reg. 1.721-1(b)(1) treats that value as income to the partner under section 61. A valuation requirement, not a 409A problem. Restricted units that vest into real equity run the same section 83 track, with the 83(b) election available, which our 83(b) election post already covers.

The entity you chose didn’t decide any of this. The award you signed did.

Profits Interests and the Rev. Proc. 93-27 Path

A properly structured profits interest is generally outside Section 409A, and it still needs a dated valuation. Those two statements aren’t in tension, and the gap between them is the most expensive misunderstanding in pass-through equity.

Rev. Proc. 93-27 section 2.01 defines a capital interest by a hypothetical liquidation test, section 2.02 defines a profits interest as “a partnership interest other than a capital interest,” and section 3 keeps receipt for services from being a taxable event. Section 4.02 carves out three situations, including a disposition within two years of receipt. Rev. Proc. 2001-43 section 4 extends the grant-date test to unvested interests. Both remain operative. Notice 2005-43 proposed a replacement built on a liquidation-value election and said the two would be obsoleted once it was finalized, and it never was, so nothing was superseded.

Q&A-7 is where 409A stops, and it stops conditionally. It shelters a profits interest only if the interest is “properly treated under applicable guidance as not resulting in inclusion of income by the service provider at the time of issuance.”

Read the conditional. The 409A exemption is bootstrapped onto the Rev. Proc. 93-27 conclusion. Set the hurdle below grant-date value and you don’t have a profits interest, you have a partial capital interest, taxable on receipt, and the Q&A-7 shelter never attaches.

That’s why profits interest valuation matters even though no Code section demands one. The valuation establishes the baseline, proving the hurdle equaled grant-date value so the award would produce nothing on a hypothetical liquidation the day after grant. In ES NPA Holding, LLC v. Commissioner, T.C. Memo. 2023-55, the Tax Court ran exactly that liquidation and found the recipient would have received nothing, against an IRS position that the figure was $12 million. The valuation was the whole case.

Two scope notes worth keeping straight.

• Section 1061 generally doesn’t reach this audience. The three-year holding rule applies to an applicable partnership interest, and IRC 1061(c)(2) limits an applicable trade or business to activity that raises or returns capital and also invests in, disposes of, or develops specified assets. An operating pass-through doing neither sits outside it, and the July 2025 reconciliation act didn’t change that test.
• GAAP doesn’t agree the award is worth zero. Tax liquidation value at grant is zero. Grant-date fair value for financial reporting isn’t. ASU 2024-01 added an illustrative example with four fact patterns for applying the ASC 718-10-15-3 scope test to profits interests, and its private-company effective date is annual periods beginning after December 15, 2025. That’s live for calendar-2026 statements.

One analysis, two numbers, and both have to reconcile. Indinero’s CPA team keeps that on one file rather than two, so the figure in the appraisal is the figure in the award schedule your auditor tests. More in our posts on ASC 718 stock comp and audit preparation.

What Gets Valued When There Is No Common Stock

With no common stock to appraise, the deliverable is a per-unit value for a named class under the operating agreement’s actual distribution waterfall. LLC equity compensation valuation starts there, not with a cap table. The work has one more layer than a corporate 409A and one fewer shortcut.

1. Enterprise value. Income approach, market approach, or both, weighted. A profitable pass-through has the advantage here. There’s EBITDA, there’s history, and a discounted cash flow has something real to discount.
2. The waterfall. Allocate equity value in the order the operating agreement actually distributes cash. Preferred units and their liquidation preferences, preferred returns, catch-ups, common units, then profits interest units above their thresholds. Our guide to preferred shares covers the preference mechanics.
3. The allocation model. A profits interest and a unit appreciation right are both economically calls on value above a strike, so the option-based toolkit in the AICPA’s valuation guide for equity securities issued as compensation applies. OPM, PWERM, the current value method, and hybrids, with a simulation where one closed-form run can’t carry the threshold. Our 409A methodology breakdown goes model by model.
4. A discount for lack of marketability, sized to stage, volatility, and expected time to a liquidity event.

A real LLC has done this on the record. Zentalis Pharmaceuticals, LLC, a Delaware limited liability company, explained its own unit valuations to the SEC in a March 2020 comment-letter response. It used the option pricing method, the probability-weighted expected return method, and a hybrid of the two, allocating value to the common units while accounting for “liquidation preferences of the holders of the Company’s preferred units.” Disclosed marketability discounts were 25 percent at the December 2018 valuation, 30 percent for the stay-private scenario and 17 percent for the IPO scenario in September 2019, and 29 percent and 14 percent respectively in December 2019. Per-unit fair values ran from $1.88 in January 2019 to $3.06 by December 2019, and the filing names the AICPA guide as its methodology source.

LLC units get valued with the same machinery as corporate common stock. The waterfall just does the work share classes do in a corporation.

The backsolve is the one thing you usually can’t have. The default corporate technique calibrates the model to the most recent priced round, solving for the enterprise value investors implied when they bought preferred. A pass-through that never raised one has no transaction to back into, so weight shifts onto the income and market approaches and the appraiser’s judgment carries the report.

S-Corp Equity Awards and the Single-Class Problem

The single-class-of-stock rule doesn’t prohibit S-corp employee options. Section 409A is the binding constraint, and most content on this topic has it backwards.

IRC 1361(b)(1)(D) says a small business corporation may not have more than one class of stock, and Treas. Reg. 1.1361-1(l)(1) implements that by asking whether shareholders have “identical rights to distribution and liquidation proceeds.” A call option can become a second class under (l)(4)(iii)(A) when exercise is substantially certain at a strike substantially below fair market value. But (l)(4)(iii)(B)(2) carves out service awards. An option issued to an employee or contractor for services, not excessive by reference to those services, nontransferable under Treas. Reg. 1.83-3(d), and without a readily ascertainable fair market value isn’t a second class of stock “regardless of its strike price,” and that holds while the option stays nontransferable.

So an S-corp can grant options. Four other things push S-corps toward synthetic awards.

• Section 409A applies at full strength. The subchapter S carve-out says nothing about 409A. A below-value strike blows the stock-rights exception exactly as it would at a C-corp, so the 409A valuation S-corp boards need before a grant is no different in substance from a C-corp’s.
• Exercise creates a real shareholder. That person has to be S-eligible, receives a pro-rata K-1 whether or not cash was distributed, and dilutes every distribution after that.
• Preference-flavored terms risk the election. Any arrangement giving one holder better distribution or liquidation economics runs at the identical-rights test. The downside isn’t a penalty, it’s a blown S election. Our C-corp versus S-corp comparison covers the broader tradeoffs.
• No profits interest is available. That concept lives in subchapter K, and an S-corp isn’t a partnership.

The real authority behind phantom and SAR designs is Treas. Reg. 1.1361-1(b)(4), which provides that an instrument isn’t outstanding stock if it conveys no right to vote, is “an unfunded and unsecured promise to pay money or property in the future,” is issued to an employee or contractor for services and isn’t excessive, and is issued under a plan that doesn’t tax the holder currently. Read those four against a phantom plan or a cash-settled appreciation right. They line up. No vote, no shareholder, no K-1, and the S election untouched. Plan mechanics live in our phantom stock post.

The cost of that elegance is that you’re now squarely inside 409A. Permissible payment events only, no acceleration, and a per-unit value you can defend at grant, at each measurement date, and at payout, where it lands as wages. Our equity compensation payroll guide covers withholding.

State exposure stacks on top. California conforms to the federal deferred-compensation rules and, under Cal. Rev. and Tax. Code section 17508.2, substitutes 5 percent for the federal 20 percent, so a failure costs 25 percent in additional tax before ordinary income tax and interest. That’s the argument for keeping award design and the Form 1120-S with the same team. At indinero, bookkeeping, accounting, tax, and fractional CFO advisory sit under one monthly engagement, so the grant-date number and the return that reports it come out of the same file.

What Changes If You Convert to a C-Corp

Converting to a C-corp doesn’t itself require a 409A valuation. The first post-conversion grant of a stock right does. Entity choice and the conversion steps belong to our small business entity guide. What follows is the valuation half.

• The trigger is the grant, not the conversion. No Code or regulation provision conditions a conversion on an appraisal. The need appears when the new corporation decides to issue options or other stock rights.
• The first true 409A is the first one that can use the safe harbors literally. Before conversion you were applying stock principles by analogy through Notice 2005-1, Q&A-7. After conversion there’s actual common stock of an actual corporation, so the independent-appraisal presumption at Treas. Reg. 1.409A-1(b)(5)(iv)(B)(2)(i) and the illiquid start-up presumption at (B)(2)(iii) apply on their own terms, with the burden of rebuttal sitting with the Service. That’s a real upgrade in the quality of the protection, not a format change. Our 409A engagement timeline covers the sequencing.
• Watch the predecessor-entity trap. The illiquid start-up presumption is unavailable to a corporation that “has no material trade or business that it or any predecessor to it has conducted for a period of 10 years or more.” Read the predecessor language. A profitable LLC operating for 12 years that converts in 2026 doesn’t get a fresh clock. Its history follows it, so the new corporation sits outside the start-up presumption on day one and relies on the independent appraisal route instead. Most founder-facing content misses this, because it was written for companies three years old.
• Outstanding pass-through awards have to land somewhere. Profits interests, unit appreciation rights, and phantom units don’t survive conversion unchanged. Whatever they convert into gets valued at the conversion date, and that analysis has to reconcile to the last pass-through valuation. The exchange-ratio math depends on it, which is also where your post-conversion cap table either ties out or doesn’t.

Twelve years of operating history doesn’t reset.

How Indinero Values Equity in Pass-Through Entities

Pass-through equity valuation starts with the operating agreement and the hurdle, because that’s where the award’s economics actually live. The 409A market wasn’t built for that. It was built around the Delaware C-corp that raised a priced round, and both the advisory models that hard-require that fact pattern and the platforms that attach valuation as a module to a cap-table subscription fit a profitable LLC or S-corp poorly.

Indinero serves bootstrapped, PE-backed, LLC, S-Corp, and multi-entity growth companies, not just VC-backed Delaware C-Corps. Three things follow from that.

• The waterfall gets read, not assumed. With no preferred price to backsolve from, the income and market approaches carry the report, and the operating agreement’s distribution order sets the allocation.
• One team holds the valuation and the return. The hurdle in the appraisal is the number in the K-1 footnote and the award schedule, because the people building it also file the Form 1065 or 1120-S. A 409A failure is a federal and a state exposure on the same return.
• The deliverable is a written report. It stays portable, and a valuation history bolted to a software subscription is only as durable as the subscription.

On cost, the pattern worth naming is that complex-waterfall work prices like its own engagement rather than a subscription add-on. Our 2026 look at 409A valuation cost and our 409A pricing breakdown walk through the variance.

Giving your team real upside shouldn’t mean rebuilding your company around a form that fits someone else’s cap table. It means getting the award right and documenting the value behind it.

Frequently asked questions

These are the questions owner-operators ask once the operating agreement is drafted and the grant is already on the next board agenda. Short answers first, with the regulation or revenue procedure cited wherever the answer turns on it. None of it replaces a read of your own distribution waterfall.

Is a profits interest subject to Section 409A?

A properly structured profits interest generally sits outside Section 409A, but the exemption is conditional, not automatic. Notice 2005-1, Q&A-7 shelters the interest only if it’s properly treated as not resulting in income inclusion at issuance, which bootstraps onto the Rev. Proc. 93-27 conclusion that the interest has zero value on a hypothetical liquidation at grant. No Code section demands an appraisal, and a dated valuation is what substantiates that baseline.

Can an S-corp grant stock options the way a C-corp does?

Yes, an S-corp can grant employee stock options, because Treas. Reg. 1.1361-1(l)(4)(iii)(B)(2) exempts a nontransferable service option from the second-class-of-stock test. That holds regardless of the strike price while the option stays nontransferable, so the binding constraint is Section 409A, not the single-class rule. A below-value strike blows the stock-rights exception at an S-corp exactly as it would at a C-corp, which is why indinero keeps the grant-date value and the Form 1120-S on one file.

Our LLC grants phantom units. Does that need an annual valuation?

Phantom units are nonqualified deferred compensation under Section 409A, so their value must be supportable at grant, though no statute requires an annual appraisal. A yearly cadence is a practical answer to grant timing and material events, not a deadline, since the 12-month figure lives inside a corporate safe harbor that doesn’t reach LLC units literally. Indinero values the unit class against your operating agreement’s waterfall, and the same team handles the Form 1065, so one number carries from grant through payout.
