This article is valuation commentary. It is not legal, tax, accounting, or investment advice. Specific engagements depend on facts and applicable professional standards.
When you need one
The practical trigger is simpler than the regulation makes it sound. You need a 409A before the first option grant, because the whole point of the valuation is to support an exercise price at or above fair market value on the grant date. If your company hasn’t granted options yet, you may not need one immediately. Once you’re going to price option grants, the strike price is also a tax-compliance line, and the regulation is explicit about how that line is supposed to be drawn.
Section 409A failures have real consequences. If an option’s exercise price is below fair market value on the grant date, the option generally becomes deferred compensation, and the consequences fall on the option recipient: current income inclusion, a 20% additional tax, and premium interest. That’s the cost of getting the FMV wrong without a defensible valuation behind it.
What safe harbor actually means
Safe harbor means the valuation is presumed reasonable unless the IRS can show it was grossly unreasonable, not that it is immune from challenge. The final regulations recognize three presumed-reasonable paths:
- Independent appraisal performed within 12 months of the relevant transaction. The most common path for venture-backed startups.
- A qualifying formula method applied consistently for relevant company purposes. Useful for some closely held situations; rarely the right answer for venture-backed companies.
- Written-report valuation of illiquid stock of a start-up corporation, performed reasonably, in good faith, and by a qualified person.
The illiquid-startup presumption has conditions that matter. It does not apply if the company reasonably anticipates a change in control within 90 days or a public offering within 180 days. It also requires a person the corporation reasonably determines is qualified, generally meaning at least five years of relevant valuation, appraisal, financial accounting, investment banking, private equity, secured lending, or comparable experience. The cheap-and-fast version of a 409A stops working as the company matures, which is when the stakes get higher.
What to prepare
The smoother the document package, the smoother the valuation. Most 409A engagements need the following inputs before the analyst can begin substantive work:
- Cap table with all share classes, options, warrants, SAFEs, and convertible notes outstanding
- Three to five years of financial statements, plus year-to-date for the current period
- Forward projections, ideally with explicit assumptions and downside cases
- Fundraising documents for each round: term sheet, certificate of incorporation amendments, stock purchase agreements
- Corporate charter and bylaws, plus any amended-and-restated versions following financings
- Stock option plan document and any sub-plans
- Recent common-stock transactions: tenders, secondaries, repurchases, transfers
- Board materials relevant to the valuation date: minutes, consents, strategic plan presentations
- Debt summary: term loans, convertible notes, revenue-based financing, ABL lines
Why a 409A differs from your fundraising valuation
This is where founders most often get surprised. A fundraising round prices preferred stock; a 409A values common stock. Those are different securities with different rights. Preferred typically carries liquidation preferences, anti-dilution protection, dividends, protective provisions, and seniority in liquidation. Common stock has none of those.
The valuation work usually starts with enterprise value and then allocates that value across the capital structure based on each class’s rights. The same company can support a $100M post-money preferred price and a $25M-equivalent fair market value for common on the same date. There is no contradiction in that. The rights stack is doing what it was negotiated to do.
A recent priced round is still relevant evidence. The regulation specifically lists arm’s-length transactions and similar-company market evidence among the factors a reasonable method should consider. But the round is an input, not an answer. Backsolve methods that work the financing back into a common-stock conclusion need to handle the specific rights of the security that just transacted, not assume them away.
What it costs and what drives the price
There’s no authoritative published fee schedule. Current market pricing runs from roughly $1,000 for entry-level early-stage engagements to $25,000+ for late-stage companies with audit-sensitive timelines and complex capital structures. Cost moves with the same factors across virtually every reputable provider:
- Company stage and complexity: a single-class pre-revenue startup costs less than a Series E with multiple preferred classes
- Capital structure: SAFEs, convertibles, warrants, multiple preferred classes, ratchets, and earnouts each add work
- Recent secondary or tender activity: requires calibration analysis under current AICPA guidance
- Audit-support requirements: clean documentation for auditor review takes more time than a simple board-package report
- Turnaround: standard is one to three weeks; rush work commands a premium
- Pre-IPO sensitivity: SEC review of cheap-stock issues raises the documentation bar substantially
When a low-cost provider is enough, and when it isn’t
- Pre-revenue or early stage with a single preferred class
- No recent secondary activity or tender offers
- Cap table is straightforward, no SAFEs or convertibles outstanding
- No looming audit, sale, or IPO review
- Limited financing history and standard rights
- Multiple preferred classes with non-standard rights
- Recent secondary, tender, or repurchase activity
- SAFEs, convertibles, warrants, or significant outstanding options
- Audit support required for ASC 718 grants
- Pre-IPO planning or cheap-stock sensitivity
- Real property, equipment, or operating-business value embedded in the entity
If a provider’s core selling point is that they can get common stock down to a fixed percentage of the last preferred round, treat that as a red flag. The regulation requires a reasonable application of a reasonable valuation method, and a rule of thumb is neither.
