What Happens to Your Options If Your 409A Lapses

Expired doesn't mean invalid — but it does mean exposed

There's an important distinction that most founders miss: an expired 409A doesn't retroactively invalidate options granted while it was current. Those grants retain their safe harbor protection. The risk applies only to options granted after expiration.

But that risk is real. Without safe harbor, the IRS doesn't presume your FMV is reasonable. Under IRC §409A(a)(1)↗, if the IRS challenges the FMV and proves it was unreasonable, the penalties land on the employees holding those options: immediate taxation, 20% additional federal penalty tax, plus interest from the vesting date. (See What Happens If You Grant Options Without a 409A for the full penalty breakdown.)

The key question isn't "did my 409A expire?" — it's "what happened during the gap?"

Assessing the actual risk

Not all lapses carry the same exposure. The risk level depends on what changed between the valuation date and the grants issued during the gap:

Low risk: nothing material changed. The company's revenue is roughly the same. No funding round closed. No major contract won or lost. No key executive departed. In this scenario, the prior FMV is likely still a reasonable approximation of fair market value — it just lacks the safe harbor presumption. An auditor might note the technical lapse but is unlikely to challenge the strike price if the underlying economics haven't shifted.

Medium risk: incremental changes occurred. The company hit a revenue milestone, hired a key executive, or made product progress. These changes might have moved the FMV modestly. The prior strike price may be defensible, but the analysis is less clear-cut. Documentation matters — if you can demonstrate that value changes during the gap were modest, the risk is manageable.

High risk: a material event occurred during the gap. A funding round closed. Revenue doubled. An LOI was received. In this scenario, the old FMV is almost certainly stale. Options granted at the old strike price after a material event are exactly the situation Section 409A↗ was designed to address. The gap between the stale price and the actual FMV at the time of grant represents the penalty exposure for each affected employee.

The fix: act immediately

Step 1: Stop granting. Do not issue any additional options until a current 409A is in place. This is non-negotiable.

Step 2: Get a current 409A. A new valuation re-establishes safe harbor from the new valuation date forward. Every grant issued after this date (within the 12-month window) is protected. The faster you close the gap, the fewer grants are exposed.

Step 3: Assess the gap-period grants. Work with your corporate counsel to evaluate whether correction is needed for options issued during the lapse. The IRS provides correction frameworks under Notice 2008-113↗ and Notice 2010-6↗. In many cases — particularly where FMV hasn't materially changed — no correction is needed. But the analysis should be documented so you can demonstrate reasonable diligence if the question arises during a fundraise, audit, or acquisition.

Step 4: Prevent it from happening again. The entire lapse scenario is preventable. It happens because nobody tracked the expiration date. An annual plan with a provider who monitors your safe harbor window and alerts you in advance eliminates this failure mode entirely. (See Your 409A Expires in 30 Days for the proactive approach.)

The hidden cost: diligence and deal leverage

Beyond the direct tax risk, a 409A lapse creates a governance signal that sophisticated parties notice. During a Series B diligence process, investor counsel reviews the full option grant history. Each grant should trace back to a current 409A. When they find a gap — grants issued during a lapse period — it triggers additional questions, additional analysis, and sometimes additional deal terms (indemnification, escrow, purchase price adjustments).

The cost of the lapse isn't just the potential penalties. It's the negotiating leverage you lose when the other side's counsel discovers a compliance gap and uses it to extract concessions.

Express 409A annual plan subscribers never face this situation. We track your safe harbor window and notify you before it expires. Your portal stays open year-round — your data is already loaded, so a refresh takes a fraction of the effort. When a material event hits mid-cycle, you request an as-needed refresh and the new valuation is delivered in 48 hours. The annual plan isn't just a discount — it's a compliance safety net that prevents the most common and most costly 409A failure mode.
