409A Valuation Compliance Guide 2025

The Complete 409A Compliance Framework

IRC Section 409A creates a comprehensive compliance framework for startup equity compensation. Understanding every element — from appraiser qualification standards to documentation retention — is essential for founders, CFOs, and legal counsel managing equity plans.

The Three Pillars of 409A Compliance

Pillar 1: Independent Qualified Appraiser

The safe harbor standard requires your 409A to be performed by a "qualified independent appraiser." Treasury Regulation §1.409A-1(b)(5)(iv)(B) defines this as someone with significant knowledge, experience, education, or training in performing valuations of similar companies or assets.

In practice, this means:

• Certified Valuation Analysts (CVA) credentialed by NACVA
• Accredited in Business Valuation (ABV) credential holders from AICPA
• CPAs with documented business valuation expertise and relevant experience
• The appraiser must be completely independent — no equity interest, employment relationship, or financial stake in the company

Company insiders (founders, CFO, board members) and investors cannot serve as the qualified appraiser, regardless of their qualifications.

Pillar 2: Appropriate Methodology

The valuation must use one or more IRS-recognised methodologies:

• Market approach: Guideline public company multiples (EV/ARR, EV/Revenue) or the backsolve method from a recent arm's-length financing
• Income approach: Discounted Cash Flow (DCF) analysis with documented assumptions
• Asset approach: Net asset value, primarily for pre-revenue or asset-heavy companies

The methodology must be appropriate for the company's stage, financial profile, and industry. Using an asset approach for a high-growth SaaS company with significant ARR, for example, would not be appropriate and could be challenged by the IRS or auditors.

Pillar 3: Written Report and Documentation

The valuation must be documented in a formal written report that includes:

• Company description and business overview as of the valuation date
• Financial data reviewed and relied upon
• Description of all methodologies applied and their respective weighting
• Comparable company or comparable transaction analysis
• Equity allocation methodology (OPM or PWERM for companies with preferred stock)
• DLOM analysis and conclusion
• Conclusion of FMV of common stock per share as of a specific valuation date
• Appraiser independence certification and credential disclosure

Maintain the following for the life of each option grant plus 7 years (to cover the IRS statute of limitations):

• Complete written 409A appraisal report
• All financial data and supporting schedules provided to the appraiser
• Cap table as of the valuation date
• Board resolution approving the FMV and authorising the option grants
• Individual option grant agreements with the strike price referencing the 409A
• Evidence of any material events considered by the appraiser
