409A valuation requirements: what section 409A asks of a startup

Updated

Section 409A is not a valuation rule with a tax attached. It is a deferred compensation rule, and options priced below fair market value drag a startup into it.

Use your provider's actual quote. The $2,000 default is a round assumption inside the range of the list prices providers publish, not a market statistic.

The regulation's presumption of reasonableness only covers an appraisal dated no more than 12 months before the grant it is used for.

A financing, a major acquisition offer, resolution of material litigation, a patent grant: anything that materially affects value makes an earlier calculation unreliable.

How this calculator works
  • Why the count matters more than the price. For stock not readily tradable on an established securities market, the regulation says fair market value means "a value determined by the reasonable application of a reasonable valuation method".
  • Using a previously calculated value is not reasonable if it fails to reflect later information that may materially affect value.
  • Nor is it reasonable if "the value was calculated with respect to a date that is more than 12 months earlier than the date for which the valuation is being used" (Treas. Reg. 1.409A-1(b)(5)(iv)(B)(1)). That is where the annual refresh and the event-driven refresh both come from.
  • The independent appraisal safe harbor. The regulation presumes a valuation is reasonable where it is "determined by an independent appraisal that meets the requirements of section 401(a)(28)(C) and the regulations as of a date that is no more than 12 months before the relevant transaction to which the valuation is applied".
  • The IRS may rebut that presumption only by showing the method or its application was "grossly unreasonable" (Treas. Reg. 1.409A-1(b)(5)(iv)(B)(2)(i)).
  • Prices are market prices, not published rates. No government body sets or publishes a 409A fee. The $2,000 default is a round assumption inside the range of the list prices providers publish today, and it is not a statistic. Ask for a written quote and use that instead: the calculator is only as good as the number you put in.
  • The count is an upper bound. Adding one valuation per year and one per material event slightly over-counts, because a valuation performed after an event also restarts the 12-month window. Treat the figure as a budgeting ceiling rather than a schedule, and take the schedule from counsel.
  • Not included. Cap table software, ASC 718 stock compensation expense reporting, audit support, secondary or tender offer valuations, QSBS attestations and state filings. Several providers bundle some of these with the 409A, which is exactly why comparing headline prices between them is misleading.
  • What is at stake if it goes wrong. Where a nonqualified deferred compensation plan fails section 409A, the deferred compensation is included in gross income. The tax is increased by premium interest plus "an amount equal to 20 percent of the compensation which is required to be included in gross income" (26 U.S.C. 409A(a)(1)(B)).
  • The cost falls on the option holder, which is why underpricing a strike price is an employee problem before it is a company problem.
  • This is general information about a US federal tax rule, not tax or legal advice, and it does not address state law. Talk to your counsel and your accountant before you rely on any of it.

Why an option grant is a tax question at all

Section 409A of the Internal Revenue Code governs nonqualified deferred compensation. A stock option granted with an exercise price at or above the fair market value of the underlying stock on the grant date is outside its scope. One granted at a discount is not, and the consequences land on the person holding the option.

Where a plan fails, the statute requires the deferred compensation to be included in gross income. The tax is increased by interest at the underpayment rate plus one percentage point. It is also increased by "an amount equal to 20 percent of the compensation which is required to be included in gross income" (26 U.S.C. 409A(a)(1)(B)).

The final regulations implementing it were issued as T.D. 9321 and published in Internal Revenue Bulletin 2007-19 (IRS).

Section 409A valuation: the general standard

For service recipient stock that is not readily tradable on an established securities market, fair market value "means a value determined by the reasonable application of a reasonable valuation method". It is judged on the facts and circumstances as of the valuation date.

The regulation lists the factors (Treas. Reg. 1.409A-1(b)(5)(iv)(B)(1)):

  • tangible and intangible assets;
  • the present value of anticipated future cash flows;
  • market values of comparable companies determined through nondiscretionary objective means;
  • recent arm's length transactions in the stock;
  • other relevant factors such as control premiums or discounts for lack of marketability.

Two sentences in that paragraph do most of the practical work. A method is not reasonable if it does not consider all available information material to value.

Using a previously calculated value is not reasonable if the calculation fails to reflect information available afterwards that may materially affect value. Nor is it reasonable if the value was calculated for a date more than 12 months before the date it is being used for.

The three presumptions

Independent appraisal
A valuation of a class of stock determined by an independent appraisal meeting the requirements of section 401(a)(28)(C) and the regulations, as of a date no more than 12 months before the relevant transaction. This is the route almost every venture-backed startup takes.
Formula price
A valuation based on a formula that would be treated as fair market value under the nonlapse restriction rules of section 83, applied consistently for every transfer of that class of stock, subject to conditions.
Illiquid start-up
A valuation made reasonably and in good faith, evidenced by a written report taking the listed factors into account, for illiquid stock of a start-up corporation: no material trade or business conducted for 10 years or more, no publicly traded equity, and no put or call obligations beyond a right of first refusal. It does not apply if a change in control is reasonably anticipated within 90 days or a public offering within 180 days.

Where a presumption applies, the IRS can only rebut it "upon a showing that either the valuation method or the application of such method was grossly unreasonable". That shift in the burden is the whole commercial value of buying a 409A valuation.

What the start-up presumption asks of the appraiser

A valuation is not treated as made reasonably and in good faith unless it is performed by a person the corporation reasonably determines is qualified. That determination rests on significant knowledge, experience, education or training.

The regulation says significant experience generally means at least five years of relevant experience in:

  • business valuation or appraisal;
  • financial accounting;
  • investment banking;
  • private equity;
  • secured lending;
  • comparable experience in the line of business or industry the company operates in.

Nothing here is tax or legal advice, and the summary above compresses a long regulation. Read the section itself, and take advice on your own facts before granting options.

Questions, answered directly

Is there a Form 409A?

No. The IRS publishes no form called Form 409A. Section 409A is the Internal Revenue Code section on nonqualified deferred compensation. The "409A" a startup buys is an appraiser's valuation report of its common stock, so options can be granted at fair market value under the regulations (Treas. Reg. 1.409A-1(b)(5)(iv)). Nothing about the report is filed with the IRS.

Is a 409A valuation legally required?

No statute requires you to buy one. Section 409A bars granting stock options at a discount to fair market value. The regulation determines fair market value by the reasonable application of a reasonable valuation method. An independent appraisal buys a presumption of reasonableness; the IRS can rebut it only by showing the method or its application was grossly unreasonable.

Who pays if a 409A valuation is wrong?

Primarily the option holder. Under 26 U.S.C. 409A(a)(1)(B) the deferred compensation is included in gross income and the tax increases by premium interest plus an amount equal to 20 percent of that compensation. The company faces reporting and withholding exposure and, in practice, a very unhappy team.
