What Is a 409A Valuation?
A 409A valuation is an independent appraisal of a private company’s common stock fair market value, conducted under IRC Section 409A to price option grants. Under Treasury Reg 1.409A-1(b)(5)(iv)(B), that appraisal is presumed reasonable for up to 12 months, unless a material event ends the presumption sooner. It exists to keep employee stock options outside the deferred-compensation penalty regime.
IRC Section 409A was enacted in 2004 under the American Jobs Creation Act to police nonqualified deferred compensation, and the statute itself sits at 26 U.S.C. Section 409A. A discounted option, one granted with a strike price below fair market value, gets treated as deferred compensation and pulled into the penalty rules. The final regulations put it the other way around: nondiscounted options with no additional deferral feature are excluded from Section 409A entirely. The valuation is what makes the option nondiscounted.
Grant at or above a defensible value and the option sits clean. Grant below it and the spread becomes taxable.
The valuation protects the option holder, not the company. That framing matters when you decide how often to refresh.
Key elements of a 409A engagement:
- Independent appraiser. A qualified valuation professional, not an internal estimate.
- Written report. A dated, defensible document you can hand to an auditor.
- Refresh cadence. Good for 12 months, or until a material event lands first.
- Safe harbor path. The method that shifts the burden of proof to the IRS.
- ASC 718 downstream. The same common stock value feeds your stock-comp expense.
Unlike a fundraising valuation, which prices preferred stock at a negotiated round, a 409A values the common stock for option-grant purposes. The two numbers are related, because the round is evidence the appraiser must use, but they are never the same number. For the full primer on scope and process, see the essential guide to 409A valuations.
Who Needs a 409A
Any private company granting employee stock options needs a 409A valuation before those options are priced. The moment you decide to hand out equity, you need a defensible strike price under IRC Section 409A.
That covers more companies than founders expect. A Delaware C-Corp issuing ISOs needs one. So does a bootstrapped company granting NSOs. The obligation attaches to the grant, not to your funding path, so you can need a 409A without ever raising a dollar of venture capital. The same logic reaches sweat equity arrangements that settle in options rather than cash.
Common moments that create the need:
- First option pool. The day you grant to early hires.
- Post-funding round. A priced round resets the value and the clock.
- M&A discussion. A live acquisition conversation is material information.
- IPO preparation. Pre-IPO option pricing draws heavy scrutiny.
The penalty for granting on an unreliable valuation falls on your team, not the company. Under 26 U.S.C. 409A(a)(1)(A), a failed grant means the deferred amount is includible in gross income once it’s no longer subject to a substantial risk of forfeiture, which for an option means as it vests, whether or not it’s exercised. Under 26 U.S.C. 409A(a)(1)(B), the tax is increased by interest at the underpayment rate plus 1 percentage point, plus an additional tax equal to 20 percent of the amount included. California layers on its own 5 percent additional tax for taxable years beginning on or after January 1, 2013, so a California employee faces a combined 25 percent. The employee pays, even though the company set the price.
The company isn’t untouched. It carries withholding and reporting exposure, plus the cost of telling employees their equity has become a tax problem. But the additional tax and interest land on the individual’s return.
The one time you don’t face immediate refresh pressure is when you aren’t granting. No new options, no urgent clock. The obligation ties to the next grant, which is exactly why timing it against your funding events matters. If you’re also weighing early-exercise and tax timing, the 83(b) election sits right next to this decision.
The Safe Harbor Framework
The safe harbor is a rebuttable presumption of reasonableness under Treasury Reg 1.409A-1(b)(5)(iv)(B), and it shifts the burden of proof to the IRS. That presumption only falls if the IRS shows the method or its application was grossly unreasonable.
The Cornell LII text of Treasury Reg 1.409A-1 lays out three qualifying paths:
- Independent appraisal method. An appraisal by a qualified independent appraiser, dated no more than 12 months before the grant, absent intervening material developments. The standard path for VC-backed and growth-stage companies.
- Illiquid startup formula method. A non-lapse restriction formula applied consistently to all transfers of that stock class. Rarely used in practice.
- Qualified individual method. A reasonable, good-faith written valuation for a company under 10 years old with no publicly traded stock. The method is unavailable when a change in control is reasonably anticipated within 90 days, or an IPO within 180 days, of the valuation date.
The qualified individual under path three must have significant valuation experience, which the preamble to T.D. 9321 in Internal Revenue Bulletin 2007-19 reads as generally five years. That bar is why most funded companies default to an independent appraiser instead.
The 409A 12 month rule lives inside that first path. Two clocks run at once. One is the calendar, 12 months from the valuation date stated in the report, not from the date the report was delivered. The other is materiality, which can stop the clock on any day. The regulation treats a valuation as unreasonable if it fails to reflect information available after the calculation date that may materially affect value, or if its valuation date is more than 12 months before the date it’s being used.
The same paragraph lists the factors a reasonable method weighs: tangible and intangible assets, the present value of anticipated cash flows, the market value of comparable entities, recent arm’s length transactions in the stock, control premiums, and discounts for lack of marketability. A priced round is a recent arm’s length transaction. That’s why it triggers a refresh even though the text never says “funding round.”
One point of precision the equity platforms tend to blur. Treasury Reg 1.409A-1 contains no post-event refresh deadline. The 90-day window you’ll see quoted is an industry planning convention and a sensible board calendar, not a legal requirement. The binding constraint is simpler and stricter: no grant can rely on the stale report once the event has occurred. For the path-by-path detail, see 409A safe harbor explained, and for a plain-language walkthrough of what voids the presumption, the eight essentials of 409A valuations.
The Valuation Methodology
A 409A valuation blends three standard approaches, income, market, and asset, then allocates enterprise value across your capital structure. The allocation step is where common stock gets its defensible number under IRC Section 409A.
The three approaches:
- Income approach. Discounted cash flow based on projected performance.
- Market approach. Guideline public companies, precedent transactions, or a backsolve to the latest preferred round.
- Asset approach. Net asset value, rarely used for a going concern.
Once enterprise value is set, the appraiser allocates it using a model from the AICPA’s Valuation of Privately-Held-Company Equity Securities Issued as Compensation, often called the Cheap Stock Guide. Three allocation methods dominate:
- Option Pricing Method (OPM). Treats each equity class as a call option on total value. Common for early and mid-stage companies with no clear exit timeline.
- Probability-Weighted Expected Return Method (PWERM). Models discrete exit scenarios, weighted by probability. Common closer to a liquidity event.
- Hybrid Method. Uses PWERM for near-term exits and OPM for the rest.
Allocation matters because your preferred stock carries liquidation preferences the common stock doesn’t. The model splits total value so the common gets its own, lower per-share figure, the number your strike price relies on. A material event can also move you between methods. As a company nears an IPO or signs an LOI, the appraiser often shifts from OPM to hybrid, because a near-term exit becomes a concrete, high-probability scenario worth modeling directly. After a priced round, the standard move is an OPM backsolve calibrated to the new preferred price, which is one reason a post-round refresh runs faster than a first valuation.
The guide itself is changing. As of September 2026, the AICPA has a working draft of the updated guide out for comment, released December 21, 2025, with comments due June 1, 2026. It’s the first full revision since 2013. The draft adds guidance on secondary transactions and repurchases, including whether those trades carry a compensatory element, and aligns the guide more closely with ASC 820 and ASC 718. Appraisers and auditors are already applying that thinking, which raises the bar for treating a tender or secondary as immaterial.
For the full method-by-method breakdown, see 409A valuation methodology explained. For context on the class being valued, this guide to how common stock gets valued covers the basics.
What Drives 409A Cost
A 409A’s cost scales with capital-structure complexity, the number of preferred classes, data readiness, and how fast you need the report. A clean single-class cap table appraises faster than a stack of preferred rounds, SAFEs, and warrants.
What moves the price and timeline:
- Complexity. More preferred classes and instruments mean more allocation work.
- Stage. A pre-revenue company and a company approaching an IPO get different treatment.
- Scenario count. Modeling multiple exit paths in PWERM adds analyst hours.
- Data readiness. Missing financials are the most common cause of delay.
- Audit exposure. A valuation headed into a financial-statement audit gets extra documentation.
- Turnaround speed. A rush request costs more than a planned refresh.
A refresh after a clean priced round is usually the cheapest and fastest report a company will buy. The appraiser already has your model built, the round supplies fresh arm’s length evidence, and the OPM backsolve to the new preferred price replaces most of the enterprise-value work. A pre-IPO quarterly report with a hybrid model and auditor review sits at the other end of the range. For dated benchmarks by provider type, see 409A valuation cost in 2026.
There’s a timing cost too, separate from the invoice. A standard engagement typically runs about two to three weeks from kickoff to final report, and a complex cap table can take four. So a grant scheduled for the week after a round closes needs its refresh started before the round closes. Treat the valuation as a line item on your financing checklist, not an afterthought once the wire lands. For the inputs that shape a quote, see what to share for 409A pricing.
When to Refresh
A 409A refresh after funding round is mandatory before your next grant, because a priced round is the clearest material event. The 12-month clock only carries you when nothing material has happened first.
Start with the default. Under Treasury Reg 1.409A-1, a qualifying appraisal is presumed reasonable for up to 12 months from its valuation date. So how often do you need 409A coverage refreshed? At minimum every 12 months, sooner on any material event, and quarterly or monthly in the 12 to 18 months before an IPO. The pre-IPO tightening isn’t a preference. SEC staff review pre-IPO grant prices under Financial Reporting Manual Section 9520 and may ask a company to explain unusually steep increases in the fair value of the underlying shares leading up to the offering. The 12-month renewal is the floor, not the answer.
A 409A material event is any development a reasonable buyer or seller would price into the stock. The regulation uses a materiality standard, not a closed checklist. In practice, these 409A refresh triggers reset the clock:
- Priced funding round. A new preferred class at a negotiated price is direct market evidence of value. Close a priced Series Seed, A, or later round and the pre-round 409A is stale for grant purposes.
- Secondary sale or tender offer. A company-sponsored tender puts a real transaction price on the common stock, and usually pushes fair market value up.
- M&A discussion or LOI. A signed letter of intent or an active acquisition negotiation is material information about value, and it also removes the qualified-individual safe harbor path.
- Major business-model change. A pivot, a new revenue line, or a doubling of ARR changes the story enough to matter.
- Material change in financial condition. A large swing in revenue or burn, the loss of an anchor customer, or a major financing shift all qualify at meaningful magnitude.
- IPO preparation. A credible near-term IPO compresses the marketability discount and invites auditor and SEC scrutiny of pre-IPO option pricing.
Refresh decision table
| Event | Refresh required before the next grant? | Why |
|---|---|---|
| Priced equity round | Yes, always | A negotiated preferred price is a recent arm’s length transaction the old report can’t reflect. |
| Single SAFE or convertible note | Usually no, on its own | Not a priced round. It changes dilution, not the common price. Disclose it and model it. |
| Accumulated SAFE stack near a priced round | Often yes | A large stack is a material change in financial condition, and conversion is near certain. |
| Company-sponsored tender offer | Yes | It creates a documented common-stock price. The AICPA draft adds guidance on secondaries and repurchases. |
| Secondary sale by a single holder | Depends on size and arm’s length character | A material arm’s length trade must be reconciled to the model. A small or related-party trade may be weighted lightly. |
| Signed LOI or active M&A talks | Yes | A credible exit shifts the method toward PWERM and removes the start-up method within 90 days of a change in control. |
| Major pivot or new revenue line | Yes, if it changes the forecast | Anticipated cash flows are a listed factor. A new forecast is new information. |
| Large revenue or burn swing | Yes, if it departs materially from prior projections | The prior report is only reasonable if it reflects current financial condition. |
| Anchor customer loss or win | Yes, if material to revenue | Concentration changes cash-flow expectations and risk. A contract above roughly a quarter of trailing revenue is presumptively material. |
| IPO preparation | Yes, and move to quarterly | SEC staff compare grant prices to the offering range. The start-up method is unavailable within 180 days of an IPO. |
| 12 months elapsed, no event | Yes | The valuation date is more than 12 months before the date of use. |
| Down round | Yes | A lower preferred price is new arm’s length evidence. Don’t reprice on the old report. |
Every “yes” row shares one logic: the prior report no longer reflects information a reasonable appraiser would have to use. The safest reading of a borderline event is to ask the appraiser in writing and keep the answer in the board file.
Here’s the failure that repeats. A company closes a priced Series A on Monday. The following week it grants 50 new option packets at the strike price from the pre-round 409A, which is now stale because the round was a material event. All 50 grants were priced off a valuation the IRS won’t respect, and all 50 sit exposed to the Section 409A penalty. The equity you meant as a reward becomes a tax bill your team never created. Refresh before, not after.
The sequence that works. The term sheet signs around day minus 21, and finance kicks off the refresh the same day with the term sheet, a pro forma cap table showing SAFE conversions, current financials, and the updated forecast. Between day minus 14 and day minus 7, the appraiser builds the model and runs the OPM backsolve to the Series A price, leaving the valuation date open. On day 0 the round closes and the final cap table goes to the appraiser that afternoon. By day 5 the report is final, dated on or after the close. On day 7 the board approves the grant batch at the new fair market value, with every grant inside the safe harbor.
The sequence that fails. On day 0 the round closes and nobody has called the appraiser. On day 1 finance requests a refresh and data gathering starts. On day 7 the board grants 50 options at the pre-round strike because the offer letters promised it. Between day 15 and day 21 the new report arrives with a higher common value, and the day-7 grants are now documented as below fair market value. The fix is a cancel-and-regrant or a repricing, with ASC 718 modification accounting and a hard conversation with 50 employees. If the refresh started late, the acceptable fallback is to defer the batch to day 21 or later. Offer letters should promise a share count, never a strike price, so a deferral costs nothing.
SAFEs and convertible notes carry a nuance worth stating plainly. A SAFE or note round in isolation usually does not force a refresh, because it isn’t a priced round and creates no new preferred class at a set per-share price. A valuation cap is a ceiling for conversion, not a valuation of the company. Three conditions push the answer from usually no to yes: the stack is large relative to the enterprise value in the last report, the caps imply a value far above it, or a priced round is imminent so conversion is near certain. Every outstanding SAFE and note must still be disclosed to the appraiser and modeled, and the priced round that converts them is always a trigger.
A down round is still a priced round, and still a trigger. A lower preferred price is new arm’s length evidence in the same way a higher one is. The refreshed 409A will usually come in lower, which is a reason to refresh promptly, not a reason to delay, since grants made on the stale number are struck above what the company now supports. If you plan to reprice underwater options, the new exercise price must be at least the fair market value on the repricing date, which requires a current report. Serial repricings invite the argument that the option carried an adjustable exercise price from the start, a Section 409A problem and an ASC 718 modification problem at once.
This is where cadence stops being a calendar problem. With indinero, 409A refresh cadence is coordinated with your funding calendar, proactive not reactive. The same team that sees the round coming already owns the refresh, so the valuation is ready before the grant. For the phase-by-phase view, see the 409A engagement timeline, and for how a valuation fits the broader raise, the financial professionals you need when fundraising.
The 409A and ASC 718 Connection
Your 409A common stock value feeds FASB ASC 718, the standard that measures stock-comp expense at grant-date fair value. A refresh protects option holders from tax penalties and keeps your financial statements honest at the same time.
The two rules are distinct but linked. A 409A is an IRS safe harbor for the option holder. FASB ASC 718, Compensation, Stock Compensation is a financial-reporting requirement for the company. The bridge is the price input. The common stock fair value from your 409A becomes the underlying-price input in the Black-Scholes-Merton model used to compute grant-date fair value, which you then expense over the vesting period. It’s usually the exercise price too. The model also needs expected volatility, expected term, a risk-free rate, dividend yield, and the vesting schedule, but the common stock value is the input a stale 409A gets wrong, and it gets two inputs wrong at once.
A stale 409A doesn’t just create tax exposure. It corrupts the compensation expense that flows through your income statement, hits EBITDA and net loss, and shows up in board reporting, lender covenants, and audit.
Nothing in the 2025 standard-setting cycle changes that. FASB issued ASU 2025-04 in May 2025 to clarify share-based consideration payable to a customer. It’s effective for annual periods beginning after December 15, 2026, with early adoption permitted, and it can’t be applied by analogy to awards granted to employees. Grant-date fair value measurement of employee options under ASC 718 is unchanged, and the 409A common value remains the underlying-price input.
Two points deserve a Controller’s attention this year. A tender offer above the 409A price can carry a compensatory element for the selling employees, which is ASC 718 expense, not just a higher value for future grants. And a repricing after a down round is a modification under ASC 718, with the incremental fair value on the modification date booked as additional expense. Both are reasons the appraiser and the controller need the same calendar.
For a Controller running an ongoing option program, 409A cadence and ASC 718 expense recognition are the same operational rhythm. Indinero’s CPA team handles both the valuation and the stock-comp calculation, so your expense, board numbers, and tax position stay consistent. The ASC 718 stock comp explained chapter covers the expense mechanics in full, and if you’re new to the underlying concept, start with how equity is accounted for.
How Indinero Approaches 409A
With indinero, 409A runs inside a year-round finance engagement, so refresh cadence tracks your funding calendar instead of a renewal reminder. The valuation isn’t a once-a-year transaction you buy and forget. It’s one deliverable inside an ongoing relationship.
Because indinero runs your bookkeeping, accounting, tax, and fractional CFO work under one monthly engagement, the same team that sees the priced round coming also owns the 409A refresh, the ASC 718 expense recognition, and the option-grant tax timing. The refresh is kicked off at term sheet, not at close, and the board’s next grant batch is scheduled after the report date rather than before it. One engagement, one calendar, no handoff between a valuation vendor and your accountant. Software-led 409A providers like Carta and Pulley treat the appraisal as a standalone product priced round by round.
The same team also owns the three things that sit next to the 409A: Section 83(b) election timing for early exercises and founder stock, modification accounting after a repricing, and the wage treatment of option-holding engineers inside the R&D tax credit. When a tender offer, a SAFE stack, or a down round changes the common value, the same people update the stock-comp schedule, the cap table, and the tax position in the same close.
Indinero also serves companies those platforms under-serve. Not just VC-backed Delaware C-Corps, but bootstrapped, PE-backed, LLC, S-Corp, and multi-entity growth companies. The firm has maintained continuous operations since 2009, serves 500+ regular customers, is SOC 2 compliant (2026), holds a 5-star Clutch rating, and prices its full-service engagement starting at $750/mo. The 409A ships as a portable written report, not a platform feature you lose when you switch cap-table tools. Your prior-year books and valuations stay with the same team, which is what auditors want to see during Series B due diligence.
A stale 409A isn’t a paperwork problem. It’s a tax bill your team didn’t create. Here’s what a different approach looks like: the refresh starts at term sheet, the grant waits for the report, and the people who close your books own both. If your next round is on the calendar, the refresh should already be in motion.

Frequently asked questions
Founders and finance leaders ask the same handful of questions about 409A refresh cadence, from priced rounds to SAFEs to stale-valuation exposure. Short, direct answers follow below.
How often do you actually need a 409A valuation?
A 409A valuation is needed every 12 months at minimum, sooner after any material event, and quarterly in the 12 to 18 months pre-IPO. Treasury Reg 1.409A-1(b)(5)(iv)(B) presumes an independent appraisal reasonable for up to 12 months from its valuation date, but a priced round, tender offer, or signed LOI ends that presumption early. The 12-month renewal is a floor, not the answer. With indinero, refresh cadence is tied to your funding calendar inside a year-round engagement, so the report is ready before the grant.
What counts as a material event that triggers a 409A refresh?
A 409A material event is any development a reasonable buyer or seller would price into your common stock, not an item on a closed checklist. Treasury Reg 1.409A-1 uses a materiality standard, and in practice the triggers are a priced round, including a down round, a company tender offer, a signed LOI, a pivot, a large revenue or burn swing, an anchor customer change, and IPO preparation. Ask the appraiser in writing on a borderline event. Indinero’s bookkeeping and CFO team already sees these events forming in your forecast.
Do I need a new 409A after closing a priced funding round?
Yes, a 409A refresh after a priced funding round is required before your next option grant, because the round is a material event. A negotiated preferred price is a recent arm’s length transaction under Treasury Reg 1.409A-1 that the pre-round report can’t reflect. A post-round refresh is an OPM backsolve to the new preferred price, about two to three weeks. Indinero kicks it off at term sheet, so the report is dated after the close and lands before the board grants.
What about a SAFE or convertible note round?
A SAFE or convertible note round on its own usually doesn’t trigger a 409A refresh, because it isn’t a priced round. A valuation cap is a conversion ceiling, not a valuation of the company. The answer flips to yes when the stack is large relative to the last report’s enterprise value, the caps imply a far higher value, or a priced round is imminent. Every SAFE and note still gets disclosed and modeled, and indinero builds that pro forma cap table into the refresh kickoff.
Does an M&A discussion or LOI trigger a refresh?
Yes, a signed LOI or active M&A negotiation is a 409A material event that requires a refresh before your next option grant. A credible exit is information about value that a reasonable appraiser must use, and it shifts the allocation method from OPM toward PWERM. Treasury Reg 1.409A-1 also removes the qualified individual safe harbor path when a change in control is reasonably anticipated within 90 days. With indinero, the same CFO team that sees the deal forming owns the refresh, so it starts when talks get serious.
Can I grant new options on a stale 409A while we’re in the middle of a refresh?
No, you can’t grant new options on a stale 409A once a material event has occurred, even while the refresh is in progress. Treasury Reg 1.409A-1 sets no 90-day refresh window, and no grant can rely on the old report after the event. Defer the batch until the new report is dated, which costs nothing if offer letters promise a share count, not a strike price. Indinero schedules the board’s grant batch after the report date, so the wait is planned, not improvised.
What is the consequence of granting on a stale 409A after a material event?
Granting on a stale 409A after a material event exposes each option holder to the Section 409A penalty, immediate income inclusion plus additional tax. Under 26 U.S.C. 409A(a)(1), the spread is includible in income as the option vests, with interest at the underpayment rate plus 1 percentage point and an additional 20 percent federal tax. California adds its own 5 percent, for a combined 25 percent. The fix is a cancel-and-regrant or repricing with ASC 718 modification accounting, which indinero’s CPA team handles alongside the refresh.
