409A valuations explained: what they cost, when you need one, and what happens if you skip it

A 409A valuation is an independent appraisal of your startup’s common stock fair market value. If you want to grant stock options with safe harbor protection from the IRS, you need one before you issue the first grant.

Most founders hear about 409A valuations for the first time when their lawyer mentions it in passing, or when a new hire asks what the strike price on their options will be. By then you’re already behind. The valuation needs to happen before you grant the first option, not after.

This post covers everything you need to know: what a 409A actually is, who needs one, what it costs, how the process works, and what happens if you decide to skip it.

Why 409A valuations exist

Section 409A of the Internal Revenue Code was enacted in 2004 as part of the American Jobs Creation Act, taking effect on January 1, 2005. It was a direct response to the deferred compensation abuses exposed at Enron, WorldCom, and Tyco, where executives accelerated payouts of deferred compensation while their companies were collapsing. Congress responded by creating strict rules around all deferred compensation, including stock options.

The core rule is simple: if you grant someone a stock option, the exercise price must be at or above the fair market value of the stock on the grant date. If you set it lower (intentionally or not), the option holder faces immediate income inclusion when the option vests, plus a 20% additional tax and an interest penalty on top of regular income tax. The tax liability falls on the employee, but in practice, affected employees frequently sue the company to recover those penalties, making it a de facto company problem too.

To prove that your exercise price was set correctly, you need an independent valuation. That’s the 409A.

Who actually needs a 409A

Not every startup needs one immediately. Here’s the breakdown.

You need a 409A if:

• You’re a C-corp that’s ready to grant stock options to employees, advisors, or contractors
• You’re issuing incentive stock options (ISOs) or non-qualified stock options (NQSOs)
• Your company has been operating long enough to have some value beyond par

You don’t need a 409A if:

• You just incorporated and are issuing founder shares at par value ($0.001/share) at or near incorporation — that’s restricted stock priced at FMV, not options
• You’re an LLC using profit interests or dynamic equity instead of stock options
• You’ve only issued SAFE notes or convertible notes (these aren’t options)
• You haven’t granted any options yet and don’t plan to soon
• You’re issuing restricted stock (not options) at the current FMV

A common point of confusion: incorporating as a C-corp doesn’t trigger a 409A requirement. Founders typically receive restricted stock at incorporation, priced at fractions of a penny. That’s not an option grant. The 409A becomes necessary later, when you want to grant options to your first hire or advisor and need to establish what the stock is actually worth.

Situation	409A needed?
Just incorporated, issuing founder shares at par value	No
C-corp granting ISOs to first employee	Yes
LLC tracking contributions with dynamic equity	No
Raised a SAFE, no options granted	No
Giving advisor 0.5% via stock options	Yes
Issuing restricted stock at FMV to co-founder	No
Planning to grant options in 3 months	Yes (get it done before the grant)

If you’re using a contribution-based equity model in the early days, you can avoid the 409A question entirely until you’re ready to formalize your cap table. Dynamic equity tracks ownership through contributions rather than stock grants, so there’s no option pricing involved.

When to get a 409A

Timing matters. A 409A valuation is valid for 12 months, or until a “material event” changes your company’s value significantly. Here are the triggers.

Before your first option grant

This is the most common trigger. You’ve hired someone, promised them options, and now you need to price those options. The 409A must be completed and documented before the board approves the grant. Retroactively setting a grant date to lock in a lower price is exactly the kind of abuse that led to Section 409A in the first place.

After a priced funding round

If you raise a Series A at a $10M valuation, your previous 409A (which might have valued common stock at $0.50/share) is stale. The material event invalidates it. You need a new one before granting any more options.

After significant business milestones

Material events go both directions. Positive ones include launching a product, hitting meaningful revenue, signing a major partnership, or receiving an acquisition offer. Negative ones count too: a down round, major layoffs, losing a key customer, or a significant pivot. Any of these can invalidate your current 409A. If you’re unsure whether something counts, ask your attorney or your 409A provider.

Annually (at minimum)

Even without a material event, the 12-month clock expires. If you’re granting options regularly, plan to update your 409A annually. Most companies time it to coincide with their board meeting cycle or fiscal year.

Before an exit or IPO

Acquirers and IPO underwriters will scrutinize your option pricing history. Missing or stale 409A valuations create problems during due diligence. Better to stay current than to scramble later.

What a 409A costs

Pricing varies widely depending on your company’s stage and complexity.

Provider type	Typical cost	Turnaround	Best for
Automated platforms (Carta, Pulley, and similar)	$1,500 - $4,000	1-2 weeks	Pre-revenue to early revenue startups
Boutique valuation firms	$3,000 - $7,000	2-4 weeks	Post-revenue, complex cap tables
Big 4 / large firms	$5,000 - $15,000+	4-8 weeks	Late-stage, pre-IPO companies

When cheap is fine

If you’re a pre-revenue startup with a simple cap table, minimal assets, and no revenue, an automated 409A from Carta or a similar platform works perfectly. The IRS cares that you got an independent valuation, not that you paid top dollar for it. At this stage, your common stock is almost certainly worth close to zero, and the methodology to prove that is straightforward.

When you need a real firm

Once you have meaningful revenue, complex financing (multiple SAFE notes, convertible notes, preferred rounds), or unusual assets (patents, real estate, crypto), the automated platforms may not capture your situation accurately. A boutique firm can apply more nuanced methodologies and defend the valuation if challenged.

What drives the price up

• Multiple classes of stock
• Complex cap tables with numerous investors
• Revenue that requires a discounted cash flow analysis
• International operations or IP
• Rushed timelines (expedite fees are real)

The cheapest 409A is the one you plan for in advance. Rush fees can double the cost.

How the process works

A 409A valuation isn’t a mystery. Here’s what happens step by step.

What you provide

Your 409A provider will ask for:

• Articles of incorporation and any amendments (the valuation firm needs to understand the rights and preferences of each share class)
• Cap table (all share classes, warrants, options outstanding)
• Financial statements (even if they’re just a P&L showing losses)
• Projections or business plan (if you have them)
• Details on recent funding rounds or SAFE notes
• Information about your market, competitors, and business model
• Any offers, LOIs, or acquisition interest

What the valuation firm does

They apply one or more accepted methodologies:

Market approach — Compares your company to similar public companies or recent private transactions. Most common for early-stage startups.

Income approach — Projects future cash flows and discounts them to present value. Used when you have revenue and can make reasonable projections.

Asset approach — Values the company based on its net assets. Rarely used for tech startups but relevant for asset-heavy businesses.

After calculating enterprise value, they apply a discount for lack of marketability (DLOM) since your shares can’t be freely traded on an exchange. DLOMs typically range from 15-40%, with most early-stage companies falling in the 25-35% range. Later-stage companies approaching an IPO may see DLOMs as low as 10-15%.

They also allocate value between preferred and common stock using an option pricing model (OPM) or probability-weighted expected return method (PWERM). This is why common stock is almost always worth significantly less than the preferred stock price from your last round.

What you get back

A 409A valuation is not an IRS form. There’s no government template you fill out and submit. What you receive is a valuation report — a formal document produced by your provider, typically 15-40 pages long. You don’t file it with the IRS. You keep it on record and produce it if you’re ever audited.

A typical 409A report includes:

• Executive summary with the concluded fair market value per share
• Company overview — your business, stage, market, and competitive position
• Financial analysis — review of your financials, projections, and key assumptions
• Methodology section — which valuation approaches were used and why
• Comparable company analysis — the public companies or private transactions used as benchmarks
• Equity allocation model — how value was split between preferred and common stock (OPM or PWERM)
• Discount for lack of marketability — the DLOM percentage applied and the rationale
• Conclusion — the final FMV per share of common stock, effective as of a specific date

For automated platforms like Carta or Pulley, the report is generated through their software and delivered as a PDF. For boutique or large firms, it’s a more bespoke document with narrative analysis. Either way, the deliverable is the same: a defensible report that documents the fair market value of your common stock on a specific date.

What you do file with the IRS: When you actually grant ISOs, the company reports each grant on Form 3921 in the year the option is exercised. The 409A report itself stays in your records — it’s the evidence behind the numbers on that form.

For the full text of the statute, see IRC Section 409A and the related Treasury Regulations.

The safe harbor

“Safe harbor” means the IRS presumes your valuation is reasonable unless they can prove otherwise. Without it, the burden of proof flips — you have to prove your valuation was correct. There are three ways to get safe harbor protection.

1. Qualified independent appraisal (most common)

This is what most people mean when they say “get a 409A.” An independent appraiser with relevant experience performs the valuation using accepted methodologies. The valuation must be no more than 12 months old, with no material events between the valuation date and the option grant date.

2. Illiquid startup safe harbor (most relevant for early-stage)

If your company has been in business fewer than 10 years and has no publicly traded stock, you can use a valuation performed by a “qualified individual” — someone with significant knowledge and experience in valuing similar companies. This doesn’t have to be a formal independent appraiser. It could be an experienced board member, angel investor, or CFO with valuation expertise. Many very early-stage startups rely on this provision. That said, using a third-party provider is still the safer bet if you can afford it.

3. Binding formula method (rare)

A predetermined formula (like book value) applied consistently for all compensation, regulatory, and transfer purposes. Rarely used by tech startups but worth knowing exists.

What happens if you skip it

Some founders skip the 409A because it feels like an unnecessary expense when the company is clearly worth next to nothing. Here’s why that’s a bad bet.

IRS penalties (they’re severe)

If the IRS determines that options were granted below fair market value:

• Income inclusion at vesting — The discounted amount is included in the option holder’s gross income when the option vests, not when it’s exercised. This means tax liability hits before the employee sees a dime.
• 20% additional tax on the option holder, on top of regular income tax
• Premium interest penalty calculated from the date the option first vests, at the IRS underpayment rate plus one percentage point

These penalties fall on your employees, not on you directly. But that distinction is cold comfort. Employees who get hit with 409A penalties routinely sue the company to recover them, turning what the IRS considers an employee penalty into a real company liability. Try recruiting engineers when your option grants carry that kind of risk.

The company’s exposure

Beyond employee lawsuits, the company has direct obligations:

• Withholding penalties — The company is required to withhold on 409A income and additional taxes. Failure to withhold exposes the company to penalties under IRC Sections 3402 and 3403. Founders can face personal liability under Section 6672 as “responsible persons” who failed to collect and remit.
• Reporting obligations — Improperly priced options require amended W-2s and corrective filings.
• State penalties — California imposes an additional 5% state penalty plus interest. Other states have similar provisions.

Due diligence problems

When you raise your Series A or get acquired, investors and acquirers will audit your option grants. Missing 409A valuations create:

• Delays in closing (weeks or months while you get retroactive valuations)
• Indemnification demands (the acquirer wants protection against future IRS claims)
• Repricing obligations (you may need to reprice every option ever granted)
• Deal risk (some acquirers walk away from messy option histories)

Real cost of skipping

A $2,000 409A today prevents a $200,000 problem during your Series A due diligence.

The math isn’t complicated. Get the valuation.

409A and dynamic equity

If you’re using a dynamic equity model to track co-founder contributions in the early days, the 409A question is simpler than you think.

Dynamic equity doesn’t require a 409A. When you’re tracking contributions and splitting ownership proportionally using a tool like Equity Matrix, you’re not granting stock options. You’re using a framework to determine future ownership allocation based on actual contributions. No options means no 409A requirement.

One important caveat: this applies when your dynamic equity arrangement is a method for determining relative ownership, not a binding promise to deliver specific shares on a specific date. If structured as a binding deferred compensation promise, it could fall under 409A. Most dynamic equity tools (including Equity Matrix) are structured correctly, but it’s worth confirming with your attorney.

The 409A clock starts when you:

1. Convert your dynamic split to a formal cap table and grant stock options to non-founders
2. Grant your first stock option to an employee, advisor, or contractor

If you’re converting from an LLC specifically to access QSBS benefits, the 409A you get at conversion also serves as the baseline FMV for the Section 1202 basis calculation. The LLC-to-C-corp QSBS strategy explains how these pieces fit together and why getting the conversion-date valuation right matters for the exclusion ceiling.

Note that incorporating as a C-corp or converting your LLC doesn’t trigger the requirement by itself. Founders typically receive restricted stock at incorporation, not options. The 409A becomes necessary when you need to price options for someone else.

This is one of the underappreciated benefits of starting with dynamic equity. You can build your team, track everyone’s contributions fairly, and defer the cost and complexity of formal equity administration until you actually need it — usually when you hire your first non-founding employee or raise a priced round.

At that point, you’ll build a cap table based on your finalized ownership percentages and get your first 409A before issuing any options.

How to choose a 409A provider

For most early-stage startups, the decision comes down to convenience vs. cost vs. defensibility.

Factor	Automated (Carta, Pulley, etc.)	Boutique firm	Large firm
Cost	Low	Medium	High
Speed	Fast	Medium	Slow
Defensibility	Good for simple cases	Strong	Strongest
Cap table integration	Built-in	Separate	Separate
Best stage	Pre-Series A	Series A through C	Pre-IPO

Questions to ask any provider:

• Do you provide safe harbor protection?
• What’s included if I get audited? (Some providers include audit defense.)
• How quickly can you turn around an update after a material event?
• What information do you need from me, and how much hand-holding do you provide?

If you’re already using Carta or Pulley for cap table management, their built-in 409A service is the path of least resistance. One platform, one login, automatic reminders when your valuation expires.

Common mistakes founders make

Granting options before the 409A is complete. The valuation must be done first. “We’ll get it retroactively” doesn’t work and creates the exact problem 409A was designed to prevent.

Using the preferred stock price as the common stock price. Your common stock is worth significantly less than what investors paid for preferred stock. Preferred shares have liquidation preferences, anti-dilution protection, and other rights that make them more valuable. Common stock typically trades at 25-40% of the preferred price for early-stage companies.

Waiting too long after a material event. If you raised a round six months ago and haven’t updated your 409A, every option you’ve granted since then is potentially mispriced.

Choosing the cheapest provider when your situation is complex. A $1,000 automated valuation works great for a pre-revenue startup with two founders and a SAFE. It doesn’t work for a company with $3M ARR, three investor classes, and international subsidiaries.

Not keeping records. Save every 409A report, every board resolution approving option grants, and every piece of supporting documentation. You’ll need them during due diligence.

Frequently asked questions

Can I do my own 409A valuation?

It depends on your stage. If your company is less than 10 years old with no publicly traded stock, the IRS allows a “qualified individual” with significant valuation experience to perform the valuation under the illiquid startup safe harbor. This could be an experienced board member, angel investor, or CFO with relevant credentials. Your co-founder with an MBA doesn’t qualify, but a board member who has valued dozens of startups might.

For the standard safe harbor (which most companies eventually graduate to), you need a formally independent appraiser. Either way, using a third-party provider is the safest path and the easiest to defend if challenged.

How often do I need to update my 409A?

At minimum, every 12 months. More frequently if you experience a material event: a funding round, a significant revenue milestone, a pivot, an acquisition offer, or a major change in your business trajectory. Most startups that actively grant options update annually, plus after each funding round.

Does a 409A set my company’s valuation for fundraising?

No. A 409A values your common stock, which is different from (and lower than) your company’s enterprise value or the price investors pay for preferred stock. Your 409A might say common stock is worth $1/share while you raise a Series A pricing preferred stock at $5/share. These aren’t contradictory. They reflect different rights, preferences, and marketability.

What if my 409A comes back higher than expected?

This happens when companies grow faster than anticipated. A higher 409A means a higher strike price on new options, which makes them less attractive to new hires. You have a few options: grant more shares to compensate, consider restricted stock units (RSUs) instead of options (though note that RSUs have their own 409A compliance requirements — they don’t eliminate the issue), or accept that your growing valuation is a good problem to have. You cannot ignore the valuation or cherry-pick a lower number.
