A 409A valuation sets the strike price on every option grant you issue, and a wrong one can trigger a 20 percent IRS penalty tax on your team's equity. Before you sign with a provider, ask about audit defense, methodology, and how they handle your actual cap table, not just price and turnaround time.
Most founders shop 409A providers on speed and cost alone. That's backwards. The report only matters the day someone questions it: an auditor, a new investor's counsel, or the IRS during an option exercise. By then it's too late to find out whether the analyst who signed your report has ever seen a cap table with three stacked SAFEs on it.
Here are the questions that actually separate a defensible valuation from a template with your company's name on it.
What a bad 409A valuation provider actually costs you
A non-compliant 409A valuation can strip your options of safe harbor protection, and the burden of proof shifts to you to show the number was reasonable. If it wasn't, employees face a 20 percent federal penalty tax on top of ordinary income rates, plus state penalties on top of that.
Pricing scales with stage: seed valuations typically run $1,000 to $2,500, Series A through C run $2,500 to $5,000 or more, and late-stage companies facing IPO or audit scrutiny can pay $5,000 to $10,000-plus, per a recent comparison of major providers. A cheap valuation that can't survive a question from your Series B lead's counsel isn't actually cheap. It's a liability you priced at a discount.
Ask who signs the report, and what happens if it's challenged
Get the name and credentials of the specific analyst who will sign your report, not just the firm's brand. Look for ASA, ABV, or CVA credentials, and ask directly: if the IRS or an auditor questions this valuation in two years, will you help us defend it, or does the engagement end when the PDF lands in your inbox?
I've sat through this question with three different providers, and the pause before the answer told me more than the answer itself. Some firms have built their entire practice around a defensible audit trail, with a named senior analyst on every engagement. Whether or not you use one of them, that's the standard to hold every provider to: a named person accountable for the number, not an anonymous template.
Ask which methodology they will use, and why
Section 409A recognizes three approaches. The income approach values you on projected future earnings. The market approach compares you to similar transactions or public companies. The asset approach values you on what you own. Which one applies depends on your stage, capital structure, and how much revenue history you have.
A provider that can't explain, in plain language, why they chose one method over another for your company is giving you a number without a defense. This matters even more if you're carrying SAFEs or convertible notes without a priced round. Ask directly how they handle that structure. It's where generalist providers most often stumble, because the standard guideline transaction method doesn't map cleanly onto unconverted instruments.
The red flags that should end the call
- They won't show you a sample report. The report is the actual product. If they won't show a redacted example for a company at your stage, that's not a confidentiality policy, it's a quality problem they don't want you to see.
- No one can tell you who's responsible if the valuation is challenged. A firm that disappears after delivery is selling you a document, not a defense.
- Pricing is bundled with no line-item breakdown. You can't compare providers on cost if you can't see what triggers a revision fee or a rush charge.
- They never ask about your SAFEs, convertible notes, or option pool changes. A 409A is only as accurate as the cap table inputs behind it. A provider working from a static spreadsheet export, with no questions about what changed since your last raise, is guessing.
The 30-day move if you're about to sign
Before you sign anything, request a sample report for a company at your stage from at least two providers, and ask both the audit-defense question and the methodology question in writing. Compare the answers side by side, not the price quotes. The cheapest provider that can't answer either question clearly is the most expensive one you could hire, because the real cost only shows up the day someone asks a question the report can't answer.
If your cap table already has stacked SAFEs, run this check alongside your cap table cleanup checklist before your next round, not after your lawyer flags a problem during diligence. And if you're not sure whether you're even due for a new valuation yet, check the events that force a new 409A before you assume the annual one is enough.
Frequently asked questions
How much does a 409A valuation cost in 2026?
Seed-stage valuations typically run $1,000 to $2,500. Series A through C companies pay $2,500 to $5,000 or more. Late-stage companies facing IPO or audit scrutiny can pay $5,000 to $10,000-plus, depending on complexity and the number of share classes.
How long does a 409A valuation take?
Straightforward cases complete in three to seven business days. Complex cap tables or multiple share classes can take up to three weeks. Rush turnarounds of 24 to 48 hours are usually available for a premium of 25 to 100 percent over standard pricing.
Do I need a new 409A valuation every year?
Yes, at minimum annually, and also after material events such as a new funding round, a major acquisition, or a significant shift in your forecasts or market conditions.
Can I switch 409A providers mid-year?
Yes, but it's uncommon outside of a problem. When you switch, make sure the new provider reviews your prior reports and can align on methodology, so you aren't introducing an inconsistency an auditor would flag.
What happens if my 409A valuation is later found to be wrong?
You can lose safe harbor protection retroactively. That shifts the burden of proof to your company and exposes employees to the 20 percent penalty tax on options they already hold, on top of ordinary income tax.
Do I need to use the same provider for my cap table and my 409A valuation?
No, but keeping them disconnected creates a real risk: if your cap table data and your valuation inputs aren't synchronized, you introduce version control gaps that an auditor can use to question the whole report.
A 409A provider isn't a form you fill out once a year. It's the document that stands between your team's equity and a tax penalty, and the only time you find out if it holds up is when you can no longer fix it. Ask the audit-defense question before you sign, not after you need the answer.
