What Is a 409A Valuation?
A 409A valuation is an independent appraisal of a private company’s common stock fair market value, set under IRC Section 409A to price option grants. 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. A discounted option, one granted with a strike price below fair market value, gets treated as deferred compensation and pulled into the penalty rules. 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. 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, and the obligation attaches to the grant, not to your funding path. You can need a 409A without ever raising a dollar of venture capital.
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 Section 409A, a failed grant triggers immediate income tax on the option spread, an additional 20 percent federal tax, and interest on the underpayment. The employee pays, even though the company set the price.
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 Regulation 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, no change of control anticipated within 90 days, and no IPO anticipated within 180 days.
The qualified individual under path three must have significant valuation experience, generally read as five or more years, which is why most funded companies default to an independent appraiser instead.
The 409A 12 month rule lives inside that first path. The presumption is good for a year, and no longer, unless material information emerges sooner. What voids the safe harbor is a material misstatement, a key omission, or a failure to refresh after a material event. For a plain-language walkthrough, see 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 and precedent transactions.
- 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, the appraiser often shifts from OPM to hybrid, because a near-term exit becomes a concrete, high-probability scenario worth modeling directly. For context on the class being valued, see this guide to how common stock gets valued.
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 triggered by a clean priced round is usually faster and cheaper than a first-time valuation. The appraiser already has your model built, and the round itself supplies fresh market evidence.
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, 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 once a year, more often when an event lands first, and on a quarterly or monthly cadence as an IPO approaches. 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.
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.
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. Two caveats: every outstanding SAFE and note must still be disclosed to the appraiser, and a large stack of SAFEs near a priced round can amount to a material change in financial condition. When those SAFEs convert at the next priced round, that round is unambiguously a trigger.
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 ASC 718, the FASB 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. The model also needs expected volatility, a risk-free rate, dividend yield, and the vesting schedule, but the common stock value is the input a stale 409A gets wrong.
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 and audit. 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. If you’re new to the underlying concept, start with how equity is accounted for.
How Indinero Approaches 409A
Indinero runs 409A 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. 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.
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.
If your next round is on the calendar, the refresh should already be in motion. See 409A valuation services for scope, or fractional CFO services for how the valuation fits your wider finance function.
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?
You need a 409A valuation at least once every 12 months, and sooner whenever a material event lands before the year is up. The 12-month presumption under Treasury Reg 1.409A-1 is the floor, not the answer. As an IPO approaches, cadence tightens to quarterly or monthly. Indinero coordinates that refresh cadence with your funding calendar inside a year-round engagement, so coverage never lapses before your next grant.
What counts as a material event that triggers a 409A refresh?
A material event is any development a reasonable buyer or seller would price into your common stock, which ends the 409A safe-harbor presumption early. Common triggers include a priced funding round, a secondary sale or tender offer, an M&A discussion or LOI, a major business-model change, and IPO preparation. The regulation uses a materiality standard, not a closed checklist. Because indinero owns your bookkeeping, tax, and CFO work under one engagement, the team spots these triggers early and starts the refresh before your next grant.
Do I need a new 409A after closing a priced funding round?
Yes, a 409A refresh after a priced funding round is mandatory before your next option grant, because the round is the clearest material event. A new preferred class at a negotiated price is direct market evidence of value, so the pre-round valuation is stale for grant purposes. Because a standard engagement runs about two to three weeks, indinero starts the refresh before the round closes, so your grants stay defensible.
What about a SAFE or convertible note round?
A SAFE or convertible note round in isolation usually does not force a 409A refresh, because it isn’t a priced round. Two caveats matter. Every outstanding SAFE and note must still be disclosed to the appraiser, and a large SAFE stack near a priced round can qualify as a material change in financial condition. When those SAFEs convert at the next priced round, that round is unambiguously a trigger. Indinero tracks your SAFE stack against the funding calendar so the refresh lands on time.
Does an M&A discussion or LOI trigger a refresh?
Yes, an M&A discussion or signed LOI triggers a 409A refresh, because active acquisition talks are material information about your company’s value. A live deal typically pushes fair market value and also removes the qualified-individual safe harbor path, since that path assumes no change of control within 90 days. Refresh before granting on a valuation that predates the conversation. Indinero coordinates the refresh so grants made during a live process stay defensible.
Can I grant new options on a stale 409A while we’re in the middle of a refresh?
No, you shouldn’t grant new options on a stale 409A once a material event has occurred, even while a refresh is underway. The safe-harbor presumption already ended, so any grant priced off the old valuation carries the same Section 409A exposure as skipping the refresh entirely. Wait for the refreshed report, then grant. Because a standard engagement runs about two to three weeks, indinero starts the refresh before the event so grants aren’t held up.
What is the consequence of granting on a stale 409A after a material event?
Granting on a stale 409A after a material event exposes every affected option to the Section 409A penalty, and the tax falls on your employees. A failed grant triggers immediate income tax on the option spread, an additional 20 percent federal tax, and interest on the underpayment. It also corrupts your ASC 718 stock-comp expense, hitting EBITDA, net loss, and audit. Indinero handles both the valuation and the ASC 718 calculation, so your tax and board numbers stay consistent.
