Your CFO hands the board a stock option grant at a $1 strike. Six months later, your tax advisor says the 409A that supported it was already stale when you issued the grants. Now every grantee faces a 20% federal penalty plus interest on the spread, and you are rebuilding a compensation plan mid-quarter.
This is the real risk behind 409A valuations. Get the process right and nobody notices it happened. Miss a trigger, use the wrong provider, or let the report expire, and the consequences fall on your employees, not a corporate account.
A 409A valuation is an independent appraisal of a private company’s common stock that sets the strike price for employee stock options and satisfies IRS Section 409A safe harbor. Without one, the IRS assumes your valuation is wrong and penalties land on the option holders.
This guide covers what a 409A is, the four events that require a fresh one, real 2026 price ranges, and whether the bundled Carta or Pulley version is good enough for your stage.
What Is a 409A Valuation?
A 409A valuation is an independent appraisal of a private company’s common stock performed by a qualified third party, used to set the fair market value (FMV) of shares for employee stock option pricing. The valuation must follow IRS Section 409A rules to qualify for safe harbor treatment, which shifts the burden of proof to the IRS if the valuation is ever challenged.
In practice, a 409A produces a per-share FMV that becomes the minimum strike price for any common stock option grants issued in the following 12 months (or until a material event occurs, whichever comes first).

Why You Need One: Safe Harbor and the 20% Penalty
The penalty structure is what makes 409A serious. If the IRS determines that options were granted below FMV without a qualifying valuation, the grant is treated as deferred compensation that fails Section 409A rules. The option holder owes:
- Ordinary income tax on the spread at vesting (not exercise)
- A 20% additional federal penalty on that spread
- Interest on the tax that should have been paid
- Potential state-level penalties (California adds another 5%)
The penalty falls on the employee, not the company, which is the part most founders underestimate. Your engineers and early hires bear the cost of your board’s valuation decisions.
The safe harbor under Section 409A exists to remove this risk. There are three ways to establish it:
- Independent appraisal method. A qualified independent appraiser conducts a valuation that meets IRS standards. This is the 409A valuation most startups use.
- Illiquid startup presumption. Applies to companies under 10 years old with no expectation of a near-term liquidity event. Requires a valuation by someone with at least five years of relevant experience, updated for material events.
- Formula method. Rarely used at venture-backed startups. Requires a formula applied consistently to all transfers of the company’s stock.
The independent appraisal method is the standard for any VC-backed company because it shifts the burden of proof to the IRS. Without it, the burden is on you to prove the valuation was reasonable, and “reasonable” is a losing argument against a trained agent with hindsight.
The Four Triggers That Require a Fresh 409A
Most founders know the “12-month rule” and stop there. There are four triggers, and the 12-month clock is just one of them.
1. The 12-Month Clock
Every 409A valuation is valid for 12 months or until a material event occurs, whichever comes first. Plan to run a fresh report every 10-11 months to avoid cutting it close on a grant date.
2. A Priced Funding Round
Any priced round (Seed, Series A, B, C, and beyond) is a material event that invalidates the prior 409A immediately. Close a round on Tuesday and issue grants on Wednesday at the old strike price, and you just issued below-FMV options to every grantee.
3. A Material Event
Broader than a funding round. The IRS considers any of these material:
- A significant acquisition or divestiture
- A major contract win or loss that changes the growth profile
- Secondary transactions at prices meaningfully different from the last 409A
- A change in business model or strategic direction
- An unsolicited acquisition offer that the board evaluates
4. Secondary Transactions
If insiders, founders, or employees sell common stock at a price different from the last 409A FMV, the IRS expects the 409A to be updated to reflect that market signal. This trips up more companies than any other trigger because secondaries often happen without a formal process.
| Event | Requires Fresh 409A? | Notes |
|---|---|---|
| 12 months since last report | Yes | Hard rule |
| Priced funding round closed | Yes | Immediate |
| SAFE or convertible note closed | Usually no | Not priced equity |
| Secondary sale at new price | Yes | Most missed trigger |
| Acquisition offer received | Maybe | Board judgment |
| Material contract win/loss | Yes if material | Document reasoning |
| Internal reorg or spinout | Yes | Changes capital structure |
409A Valuation Cost in 2026: Real Price Ranges
Pricing has stratified significantly since 2020. The market now splits into three tiers.
Bundled with equity management software (Carta, Pulley, Cake): Typically ranging from free to around $3,000 per report, depending on the plan tier. Often included with higher-tier cap-table subscriptions. Turnaround of 2-3 weeks. Best for Seed and early Series A companies with standard capital structures.
Mid-market standalone firms: Approximately $3,000-$7,500 per report. Independent valuation firms that do 409As alongside other valuation work. Better at complex cap tables, secondaries, and companies approaching IPO or acquisition. Turnaround of 2-4 weeks.
Top-tier boutique and Big 4: Roughly $7,500-$25,000+ per report. Used by late-stage companies, pre-IPO, and businesses with audit exposure that need a defendable valuation opinion. Turnaround varies by complexity.
| Company Stage | Cap Table Complexity | Typical Price Range | Best Fit |
|---|---|---|---|
| Pre-seed / Seed | Simple (founders + SAFEs) | $0-$2,500 | Bundled provider |
| Series A | Priced preferred, standard terms | $2,500-$5,000 | Bundled or mid-market |
| Series B | Multiple preferred classes, early secondaries | $4,000-$8,000 | Mid-market standalone |
| Series C+ | Complex cap table, secondaries, potential audit | $7,000-$15,000 | Standalone or boutique |
| Pre-IPO / Late stage | Full audit exposure, strategic events | $12,000-$25,000+ | Boutique or Big 4 |
What drives cost up within a tier: multiple preferred share classes, participating preferred or other non-standard liquidation preferences, significant secondary activity, complex option pool mechanics, international subsidiaries, and recent M&A activity.
Bundled vs. Independent: When Each Option Wins
Carta and Pulley built 409A into their cap-table platforms because it is a natural extension of the data they already hold. For most early-stage companies, the bundled product is fine. For some, it is not.
Bundled works when:
- Your cap table is standard (founders, employees, a handful of preferred classes from priced rounds)
- You have no secondaries, no unusual structures, no complex waterfall
- You are pre-audit, no public filings, no Big 4 audit requirement
- You are Seed or Series A
- You trust the platform’s methodology and want speed
Standalone is worth the premium when:
- You have complex preferred stock with participating or stacked liquidation preferences
- Secondary transactions have happened at material prices
- You are approaching audit scope, either for a future IPO or a Big 4 audit engagement
- You anticipate an acquisition where the 409A will be scrutinized in diligence
- You have had valuation disputes in the past or expect IRS attention
- You want an appraiser willing to defend the report under examination
The single most important factor is audit exposure. Big 4 auditors will review the methodology of any 409A underlying option expense (ASC 718). Bundled reports get rejected or force-adjusted more often than standalone reports at companies with serious audit requirements. Not because bundled is wrong, because standalone firms produce more defensible workpapers.
A useful middle path: use bundled from Seed through early Series A to save money, then transition to a standalone firm at Series B or the first sign of audit exposure. A fractional CFO can run the provider selection process and manage the transition cleanly.
The 409A Process: Timeline and What Providers Need
A standard 409A takes 10-20 business days from kickoff to final report. The timeline breaks down roughly as follows:
Days 1-3: Kickoff and data request. Provider sends a request list. You assemble documents.
Days 4-10: Data review and analysis. Provider models the waterfall, selects valuation methodologies (usually Option Pricing Method, Probability-Weighted Expected Return Method, or a hybrid), and calculates FMV.
Days 11-15: Draft report and review. Provider delivers a draft. Your CFO or outside advisor reviews assumptions. Questions and adjustments.
Days 16-20: Final report delivered.
What the provider will ask for:
- Current cap table (with all convertible instruments)
- Most recent financial statements and trailing 12 months
- Operating forecast or financial model (next 12-36 months)
- Term sheets and financing documents for all priced rounds
- Most recent board deck
- Any secondary transaction records
- Recent 409A report if this is a refresh
The data request is the bottleneck. Companies that cannot produce clean financials and a current forecast add a week to the process while their team scrambles. This is why outsourced accounting with consistent monthly close often pays for itself at 409A time alone.
After Your 409A: Grant Pricing and Refresh Cycles
The report lands. Your common stock FMV is set. Here is what happens next.
Grant pricing. All option grants issued after the valuation date must carry a strike price at or above the new FMV. Grants in flight that were approved before the 409A but not yet issued need to reprice to the new FMV.
Refresh planning. Calendar the next 409A for month 10 or 11. Do not let it roll to month 12. Grants issued in the gap between expiration and a new report carry risk.
Event watching. Assign someone (usually the CFO or head of finance) to flag material events as they occur. The cost of a mid-cycle refresh is always lower than the cost of a missed trigger.
Documentation. Keep the full report, the engagement letter, and the appraiser’s credentials. If the IRS ever challenges, this paperwork is what establishes safe harbor.
Frequently Asked Questions
How often do you need a 409A valuation?
At minimum every 12 months, or sooner if a material event occurs. Material events include priced funding rounds, secondary transactions, acquisitions, and significant business changes. Most venture-backed startups end up running a new 409A every 8-11 months because events trigger refreshes before the full year is up.
Can you do a 409A valuation yourself?
Technically yes, under the “illiquid startup presumption,” but it does not provide true safe harbor protection. The appraisal must be performed by someone with at least five years of relevant valuation experience. Most founders and CFOs do not meet that bar, which is why independent third-party valuations are the standard at any VC-backed company.
Does a SAFE or convertible note trigger a 409A?
Typically no. SAFEs and convertible notes are not priced equity rounds, so they do not reset the 409A clock. The next priced round that converts them does. Some providers will factor in recent SAFE activity as evidence of enterprise value, but the instrument itself is not a trigger.
What happens if your 409A expires?
Any stock options granted during the expired period are at risk of failing Section 409A safe harbor. The fix is to run a fresh 409A immediately and either reprice the affected grants to the new FMV or replace them. The IRS Section 409A correction program (Notice 2008-113) covers some scenarios, but not all. Better to not let it expire.
How does a 409A differ from a business valuation?
A 409A is specifically an appraisal of common stock FMV for IRS compliance purposes. A business valuation (for M&A, estate planning, or dispute resolution) values the whole enterprise and uses different standards. They often rely on overlapping methodologies but serve different audiences and obligations.
The Takeaway
A 409A valuation is tax infrastructure, not a nice-to-have. The 20% penalty falls on your employees, which is why getting it right matters more than it seems. The 12-month clock is only one of four triggers, and priced rounds reset it instantly. Bundled Carta or Pulley 409As work fine for most Seed and Series A companies with clean cap tables. Standalone firms earn their premium when audit exposure, complex capital structure, or secondary transactions enter the picture.
