Best 409A Valuation Providers 2026 [Price Compared]

You need a 409A valuation. The price range runs from $499 to $15,000. Which providers and services are the best fit for your startup? The answer depends heavily on your funding stage, capital structure complexity, and whether you anticipate a Big 4 audit in the near future.

If you are new to 409A requirements, start with our complete guide to 409A valuations for startups.

This guide evaluates the top firms across five criteria: price transparency, AICPA compliance quality, turnaround time, audit support, and stage fit. We reviewed publicly available pricing, analyzed compliance documentation standards, and assessed audit defensibility for each provider category. Whether you are comparing providers by cost or simply trying to avoid overpaying, this breakdown gives you a clear decision framework.

How We Evaluated 409A Valuation Providers

Selecting the right provider is not simply a matter of finding the lowest price. A 409A that fails an IRS audit or lacks a qualified appraiser signature exposes your company and your option holders to serious tax consequences under IRC Section 409A. With that regulatory reality as the baseline, we evaluated each provider across five criteria.

1. Price Transparency

Does the provider publish starting prices clearly? Hidden fees, bundled equity management subscriptions, and per-revision charges inflate the true cost of many services.

2. Compliance Quality

Is the valuation signed by a qualified appraiser as defined under Treasury Regulation Section 1.409A-1(b)(5)(iv)? Does the report follow the AICPA Statement on Standards for Valuation Services No. 1 (SSVS 1)? Note: AICPA compliance (adherence to professional valuation standards) and IRS safe harbor (the presumption of reasonableness under Section 409A) are related but distinct standards. A valuation can be AICPA compliant without automatically qualifying for safe harbor if other requirements — such as the qualified appraiser requirement — are not met. Both are non-negotiable.

3. Turnaround Time

Option grants cannot be issued below fair market value. When you need a 409A to make a hire or close a grant cycle, turnaround time has direct operational consequences.

4. Audit Support

If the IRS or your financial auditors question the valuation, will the provider defend it? Some affordable 409A valuation services include this as standard; others charge separately.

5. Stage Fit

A pre-IPO company has fundamentally different valuation complexity than a pre-seed startup. We evaluated whether each provider category is appropriately matched to the capital structure and regulatory scrutiny typical of each funding stage.

Top 409A Valuation Providers Compared by Price [2026]

The table below represents the best available public pricing data as of February 2026.

How to read this table: "Starting price" reflects the entry-level cost for a straightforward early-stage startup. Companies with complex capital structures will pay more at every provider. "Safe harbor eligible" means the report is prepared by a qualified appraiser using AICPA compliant methodology, which qualifies for the IRS safe harbor presumption of reasonableness under Section 409A. Audit support reflects whether the provider will respond to auditor or IRS inquiries at no additional cost.

Best 409A Valuation Firms for Seed-Stage Startups

Best 409A Valuation for Early-Stage Startups

For founders asking which firms are best for seed-stage companies, the answer is straightforward: you almost certainly do not need to spend more than $499 to $1,500.

Seed-stage companies typically have simple capital structures — common stock, perhaps a SAFE or convertible note, no preferred series with complex liquidation preferences. The OPM backsolve methodology is well-established for this stage, and the analytical complexity is low. The AICPA standards applied to a seed-stage company are the same standards applied at any stage; the complexity of inputs simply differs.

Recommended providers for seed stage:

409A Valuation (409a-valuation.com) — At $499, this is the strongest option available. Full AICPA compliance, qualified appraiser signatory, IRS safe harbor eligibility, and a 2-5 business day turnaround.

Scalar — A reasonable mid-tier choice at roughly $1,500-$2,500. Scalar has built a strong reputation among venture-backed startups with solid compliance documentation.

Kruze Consulting — At $2,000, Kruze makes sense if you are already using their accounting services and want a bundled relationship.

Best 409A Valuation Options from Seed to Pre-IPO

The best options from seed to pre-IPO differ meaningfully by stage. As capital structure complexity grows, the appropriate provider type shifts.

What genuinely changes at Series C and beyond is the audit environment — financial statement auditors scrutinize 409A valuations more carefully, and the cost of a challenged valuation increases substantially. That is when the premium for a boutique or Big 4 engagement begins to pay for itself.

409A Valuation Provider Reviews: 2026 Deep Dives

409A Valuation (409a-valuation.com) — Review

Pricing: From $499

Turnaround: 2-5 business days

Best for: Pre-seed through Series B

IRS Safe Harbor: Yes

409a-valuation.com is an AI-powered valuation platform that delivers AICPA compliant 409A reports signed by a qualified appraiser. The platform uses automated data collection and expert review to achieve a starting price of $499 — the lowest price currently available from a provider that delivers all required safe harbor elements.

What you get: A full valuation report prepared under AICPA SSVS 1 standards, signed by a qualified appraiser, IRS safe harbor eligible, with documentation suitable for financial statement audit support. The report includes market approach analysis, income approach consideration, and OPM or PWERM allocation as appropriate.

Who it is best for: Early-stage startups from pre-seed through Series B, including companies with convertible instruments requiring complex OPM allocations. Particularly well-suited for companies that need fast turnaround to close a grant cycle.

Key limitation: Not recommended for pre-IPO companies facing Big 4 audit requirements or M&A transactions where counterparty advisors will scrutinize valuation history.

Overall: 5/5 for early-stage startups through Series B. Not the right choice for pre-IPO.

Carta 409A Review

Pricing: ~$2,000-$3,000 for early-stage; higher for complex structures

Turnaround: 2-3 weeks

Best for: Companies already using Carta for cap table management

IRS Safe Harbor: Yes

Carta 409A is among the most recognized names in startup valuation, largely because of Carta's dominant position in equity management software. Their valuation services benefit from tight integration with cap table data — if your company already manages equity on Carta, the data transfer process is seamless.

What you get: An AICPA compliant report prepared by Carta's internal valuation team, IRS safe harbor eligible, with audit support through Carta's platform.

Who it is best for: Companies already paying for Carta's equity management platform. For Series A and above companies embedded in the Carta ecosystem, this is a reasonable choice.

Key limitation: Approximately four times more expensive than AI-powered alternatives for an equivalent compliance outcome at seed and Series A. The 2-3 week turnaround is also meaningfully slower.

Overall: 3/5 for cost-conscious startups. If you are not already on Carta's platform, the premium is difficult to justify.

Kruze Consulting 409A Review

Pricing: ~$2,000 (seed) to $3,500 (Series C)

Turnaround: 1-2 weeks

Best for: Startups wanting bundled accounting and valuation

IRS Safe Harbor: Yes

Kruze Consulting has established a strong reputation as a full-service accounting and financial advisory firm focused on venture-backed startups. Their 409A valuations are offered as part of a broader accounting relationship, creating genuine efficiency for companies that use Kruze for CFO services, bookkeeping, or tax preparation.

What you get: AICPA compliant valuation with a qualified appraiser signatory. Kruze has deep experience with venture-backed capital structures and maintains solid audit defensibility across Series A through Series C.

Who it is best for: Startups already engaged with Kruze for accounting services, where financial data flows efficiently into the valuation process.

Key limitation: At $2,000 for seed-stage, four times more expensive than AI-powered alternatives for equivalent compliance quality.

Overall: 4/5 for existing Kruze clients. 3/5 if evaluating independently.

Andersen 409A Review

Pricing: ~$3,000-$7,000 depending on stage and complexity

Turnaround: 2-4 weeks

Best for: Series B through pre-IPO, mid-market complexity

IRS Safe Harbor: Yes

Andersen (formerly WTAS) is a global professional services firm with substantial valuation practice depth, positioned between boutique specialists and Big 4 firms — capable of handling significant capital structure complexity while being more accessible than the Big 4.

What you get: Full AICPA compliant valuation prepared by experienced credentialed professionals (CVA, ASA, ABV, or equivalent credential with demonstrated business valuation experience), with robust documentation suitable for complex financial statement audits.

Who it is best for: Companies at Series B or later anticipating heightened auditor scrutiny, exploring M&A, or with complex capital structures. Pre-IPO companies sometimes use Andersen as a cost-effective alternative to Big 4.

Key limitation: Not competitive for early-stage startups where compliance requirements are identical but complexity is far lower.

Overall: 4/5 for Series B and later. Not appropriate for seed or Series A on a price-to-value basis.

Big 4 Firms (Deloitte, EY, PwC, KPMG) — When to Use Them

Pricing: $8,000-$15,000+; can exceed $25,000 for complex pre-IPO situations

Turnaround: 4-8 weeks

Best for: Pre-IPO, M&A targets, companies with Big 4 auditors

IRS Safe Harbor: Yes

The Big 4 accounting firms represent the highest tier in terms of both price and institutional credibility. For the vast majority of startups, their services represent significant overspend. However, there are specific scenarios where a Big 4 firm is the correct choice.

What you get: A valuation prepared by a dedicated financial advisory practice with senior credentialed professionals, deep access to proprietary market databases, and full institutional backing.

When you genuinely need Big 4:

• Your financial statement auditor is a Big 4 firm and has communicated a preference for a 409A from a recognized provider
• You are filing an S-1 or preparing for an IPO within 12-18 months
• Your company is a likely M&A target and the acquirer's advisors will scrutinize your equity compensation valuation history
• You have greater than $100M in outstanding equity compensation with significant tax exposure

Key limitation: The premium is not justified by compliance quality for early-stage companies. A Big 4 firm applies the same OPM methodology and AICPA standards as an AI-powered platform — the difference is institutional credibility in high-scrutiny environments.

Overall: 5/5 for pre-IPO and Big 4 audit environments. 2/5 for seed through Series B.

What Really Matters When Comparing Providers

The cost dimension is where most founders focus — and it matters — but price should be evaluated in context.

Price vs. Value: Understanding Total Cost of Ownership

The 409A valuation cost over a startup's lifecycle adds up quickly. Most companies need annual updates, plus additional valuations triggered by new funding rounds or material events (typically 12 months maximum between valuations).

Four-year total cost of ownership comparison:

For a startup that raises a seed round, then a Series A two years later, and requires annual updates, the difference between an affordable provider and a boutique firm is approximately $10,000 over four years — with no difference in compliance outcome. That capital is better deployed in product development, hiring, or runway extension.

Compliance Is Non-Negotiable: How to Verify a Provider

Before signing with any provider, confirm:

• Report signed by a qualified appraiser under Treasury Reg. Section 1.409A-1(b)(5)(iv)
• AICPA compliant methodology under SSVS 1
• Recognized valuation method: OPM backsolve, PWERM, or hybrid
• Professional credentials: ASA, ABV, or equivalent credential with demonstrated business valuation experience (CVA is also a legitimate valuation credential)
• Audit support included in the quoted price
• Documentation suitable for financial statement audit review
• Experience with your specific capital structure (SAFEs, convertibles, complex waterfall)

The provider that meets all of these criteria at the lowest cost is the correct choice for most startups. See mistakes founders make when choosing a 409A provider for common errors in provider selection.

Turnaround Time Matters More Than You Think

Most founders underestimate how often turnaround time creates real operational pain. Your 409A has lapsed and you are closing a key hire whose offer includes options — a 4-8 week wait means delaying the grant or issuing at a stale price. Your board approved a new option pool post-Series A — a 2-3 week delay means the team waits for promised equity. A material event may require an update — getting clarity quickly protects the company.

A 2-5 business day turnaround from an AI-powered platform eliminates these scenarios. The 2-3 week turnaround typical of Carta and boutique firms is not a minor inconvenience — it is a recurring operational constraint.

Conclusion

For seed and Series A startups — the majority of companies actively managing 409A valuations — the analysis is clear. An AI-powered platform delivering full AICPA compliance and qualified appraiser sign-off at $499 is the best option available. The compliance outcome is equivalent to boutique firms charging four to six times as much, and the turnaround time is faster.

The decision to spend more is only justified when your audit environment demands it. Pre-IPO companies, M&A targets, and companies with Big 4 auditors have legitimate reasons to engage higher-cost providers. Everyone else is paying a premium for brand recognition that does not translate into better protection.

The right service for your company is the one that meets the IRS qualified appraiser requirement, follows AICPA compliant methodology, and delivers in a timeframe that supports your operational needs — at the lowest cost that satisfies those criteria.
