Understanding 409A Safe Harbor: What Every Founder Must Know

Stay compliant. Avoid fines. Build trust.

You need to determine the Fair Market Value (FMV) of your common shares if you offer your employees stock options. This is when IRC Section 409A comes into play. What happens if you neglect accurate valuation?

You are at risk:

Penalty for taxes at the time of vesting
A 20% IRS fine
Interest on taxes that are not paid
Audits and legal issues
Which way is the safest? An evaluation of a 409A safe harbour.

What Is A 409A Safe Harbour Valuation?

A certified appraisal of your company’s common stock that satisfies IRS requirements is a 409A Safe Harbour value.

If done correctly, it gives you a “safe harbour presumption,” which transfers the burden of evidence to the IRS if it is questioned.

This valuation protects you and your staff from potential tax problems and fines associated with stock option pricing.

Three Safe Harbour Techniques Approved by the IRS

You can use any of the following strategies to be eligible for Safe Harbour:

1. The Most Reliable Independent Third-Party Valuation

Carried out by experts such as Transaction Capital LLC
IRS-approved as the best defendable approach
It is valid for a whole year until your business experiences a significant change.

Why choose this?

It’s the safest and most popular method of cap table protection.

2. Formula-Based Valuation

Typical for businesses with set redemption formulas or LLCs
It must be used consistently in every transaction.

Warning: Only adequate if you don’t intend to raise money or change ownership.

3. The Illiquid Startup Approach

For startup businesses under ten years old
It cannot be getting ready for an acquisition or IPO.

Ideal for: New businesses with little financial history and no imminent liquidity issues.

Dangers of Ignoring 409A Compliance

Ignoring or improperly managing 409A value might result in:

Serious Tax Repercussions

When options vest but are not exercised, immediate taxation
IRS penalty of 20%
Interest that is compounded on late tax payments

Operational and Legal Risks

Lawsuits by shareholders
Disruptions to M&A deals
A decline in investor trust
Having trouble keeping elite talent

Common Mistakes That Invalidate Safe Harbor

Stay away from these typical mistakes:

Making use of out-of-date post-finance valuations
Using non-certified internal evaluations
Inconsistent documentation or projections that are out of alignment
Leaving the valuation unchanged following significant occurrences (fundraising, critical hires, etc.)
