Your startup's 409A valuation determines your stock option strike price—directly affecting your potential profit. This guide explains what 409A valuations are, how they work, and why they matter for your equity value.
The Short Answer
A 409A valuation is an independent appraisal of a startup's fair market value (FMV), required by the IRS. It determines the strike price for employee stock options—the price you pay to exercise your options.
409A and Your Strike Price
Your company's 409A valuation: $8/share
Your option strike price: $8/share (must be ≥ FMV)
If company exits at $50/share: You pay $8, gain $42/share
Higher 409A valuation = higher strike price = lower potential profit. Lower 409A valuation = lower strike price = higher potential profit.
What Is a 409A Valuation?
Named after IRS Section 409A, a 409A valuation is an independent assessment of what a startup's common stock is worth. It's not the same as the valuation from venture capital funding rounds—that's for preferred stock. 409A valuations are for common stock, which is what employees receive.
Why 409A Exists
The IRS requires 409A valuations to prevent companies from issuing stock options at artificially low strike prices (which would let employees avoid taxes). Without a valid 409A valuation, option grants could be taxed as ordinary income immediately, with penalties.
How Often 409A Valuations Happen
Most startups get a 409A valuation:
- Annually — Every 12 months
- After funding rounds — When preferred stock is sold at a new price
- After major events — Mergers, acquisitions, or significant business changes
⚠️ Expiration Matters
409A valuations are valid for up to 12 months. If a company doesn't renew its 409A, it can't issue new stock options until it gets a fresh valuation.
How 409A Affects Your Stock Options
The 409A valuation directly determines your strike price. Here's the impact:
Scenario: Low 409A Valuation (Good for You)
409A valuation: $2/share
Your strike price: $2/share
Exit value: $50/share
Your gain: $48/share
On 10,000 options: $480,000 profit
Scenario: High 409A Valuation (Less Good for You)
409A valuation: $20/share
Your strike price: $20/share
Exit value: $50/share
Your gain: $30/share
On 10,000 options: $300,000 profit
The difference: $180,000 in lost profit due to a higher 409A valuation. This is why 409A timing matters for your equity.
How 409A Differs from Funding Valuations
Startups have two types of valuations that often confuse people:
| Factor | 409A Valuation | Funding Valuation |
|---|---|---|
| What's valued | Common stock (employee equity) | Preferred stock (investor equity) |
| Purpose | Set strike prices for options | Set price for investor shares |
| Who buys | Employees (via options) | Venture capitalists |
| Value level | Lower (illiquid, no preferences) | Higher (liquidation preferences) |
| Validity | 12 months | Until next funding round |
| Who pays | Startup ($5K-$15K) | Investors (they pay for shares) |
The Valuation Gap
Funding valuations (preferred stock) are typically 2-5x higher than 409A valuations (common stock). This gap exists because preferred stock has liquidation preferences and other rights that common stock lacks.
Valuation Gap Example
Funding round (Series A): $40M valuation (preferred)
409A valuation: $12M valuation (common)
Gap: 3.3x difference
When 409A Matters Most
1. Early Employees (Pre-Series B)
If you join early, your strike price is set when the 409A is low. As the company grows and raises funding, the 409A increases—but your strike price stays locked in. This is the equity goldmine scenario.
Early Employee Advantage
Join date: Seed stage, 409A at $1/share
Your strike price: $1/share (locked forever)
Company grows to Series B: 409A now $10/share
New hires pay: $10/share
You keep: $9/share advantage on all your options
2. Late-Stage Employees (Series C+)
Joining later means your strike price reflects the company's accumulated growth. Your potential profit is smaller because you're paying more for your options.
Late Employee Disadvantage
Join date: Series C, 409A at $25/share
Your strike price: $25/share
Exit value: $50/share
Your gain: $25/share (versus $49/share for early hires at $1)
3. Between Funding Rounds
If you join between funding rounds, your strike price is based on the most recent 409A. If funding is imminent, the 409A might increase soon—locking in your strike price before the bump is valuable.
Can You Negotiate Strike Price?
No. Strike prices must be at or above the 409A FMV to comply with IRS rules. Companies cannot legally grant options below the 409A valuation without risking tax penalties for everyone.
⚠️ Don't Ask for Lower Strike Prices
Asking for a strike price below 409A FMV signals you don't understand how equity works. It can't be done legally. Instead, negotiate for more options (a larger percentage grant), not a lower strike price.
What You CAN Negotiate
Since strike price is fixed by 409A, negotiate these instead:
- Number of options: Ask for more options to increase your total equity percentage
- Grant timing: Ask for your grant before a funding round (if one is coming soon)
- Refresh grants: Ask for additional options if you've been there for years and the 409A has increased significantly

How to Find Your Company's 409A Valuation
You typically won't find 409A valuations publicly. Try these approaches:
- Ask directly: “What's the current 409A valuation and strike price for my grant?”
- Check your offer letter: Strike price should be listed
- Ask your equity administrator: HR or the person managing equity (Carta, Pulley, etc.)
- Ask during interviews: “What's the current 409A valuation range?”
⚠️ Companies May Hesitate to Share 409A
Some startups view 409A valuations as confidential. However, your strike price directly affects your potential profit—you have a right to know it before accepting an offer.
409A and Taxes
The 409A valuation determines your tax situation:
For ISOs (Incentive Stock Options)
- No tax at grant: No tax when options are granted (strike equals 409A FMV)
- AMT possible at exercise: If spread between strike and FMV is large
- Capital gains at sale: If you hold 1+ year post-exercise
For NSOs (Non-Qualified Stock Options)
- No tax at grant: No tax when options are granted
- Ordinary income at exercise: Spread (current FMV - strike) is taxable
The lower your strike price (based on 409A), the larger your potential spread—and the larger your potential tax bill at exercise.

Red Flags: 409A Issues to Watch
Stale 409A Valuation
If your company hasn't updated its 409A in over 12 months, it may be issuing options illegally. Ask: “When was the last 409A valuation?”
Strike Price Below 409A FMV
If your strike price seems too low (well below market), the company might be granting options illegally. This could trigger tax penalties for you later.
Refusal to Disclose Strike Price
If the company won't tell you the strike price or 409A valuation before you accept the offer, that's a red flag. You need this information to evaluate your equity.
Massive Gap Between Funding and 409A
If funding valuation is $100M but 409A is $10M (10x gap), ask why. Gaps are normal but 10x+ is unusually large and may indicate aggressive 409A positioning.
Key Takeaways
- 409A determines strike price — Your option exercise cost is set by the 409A valuation
- Lower 409A = lower strike price = higher potential profit — Early employees benefit most
- 409A ≠ funding valuation — 409A is for common stock (employees), funding is for preferred stock (investors)
- 409A is updated annually — Strike prices increase as the company grows
- You can't negotiate strike price — It must be at or above 409A FMV. Negotiate more options instead.
- Ask for the 409A valuation — You need to know your strike price before accepting an offer
- Watch for red flags — Stale 409As, unusually low strike prices, or refusal to disclose

Frequently Asked Questions
How much does a 409A valuation cost?
Typically $5,000-$15,000, depending on company complexity and the appraisal firm. Startups pay this cost—they need valid 409A valuations to issue stock options to employees legally. The cost is considered a business expense.
What happens if a company doesn't have a 409A valuation?
They can't issue stock options to employees without risking IRS penalties. Options granted without a valid 409A may be taxed as ordinary income immediately, and the company could face fines. Most startups get annual 409A valuations specifically to issue options legally.
How often do 409A valuations change?
Every 12 months, or sooner if there's a material event like a funding round, merger, or significant change in business. Most startups update 409A valuations annually to maintain compliance and set accurate strike prices for new hires.
Does a higher funding round increase my strike price?
Only if the 409A valuation is updated after the funding. Funding rounds (preferred stock) don't directly affect 409A (common stock), but most startups do update their 409A after raising money. If you have options already granted, your strike price stays the same—only new hires get the higher strike price.
Should I exercise before a 409A valuation increases?
If you're planning to exercise anyway, doing it before a 409A increase can lock in a lower strike price for new grants (if you're getting refresh grants). For existing options, your strike price is already set—409A changes don't affect already-granted options. Exercise timing should focus on your tax situation, not 409A changes.
