How to File an Official Section 83(b) Election with the IRS

The IRS 83(b) election for restricted stock within 30 days must be an official, signed filing with the Internal Revenue Service—typically IRS Form 15620 (April 2025 revision) or a written statement that satisfies Treasury Regulation §1.83-2—mailed to the same IRS service center where you file your federal income tax return, with a copy furnished to your employer and a copy attached to your Form 1040 for the year of transfer. You have 30 calendar days from the Section 83 transfer date (not your offer letter date). Missing that window generally forecloses the election for that transfer.

30calendar days — statutory filing window from property transfer (IRC §83(b))Verified against IRS Form 15620 instructions (April 2025), accessed 21 May 2026.

Who must file (and who should stop reading)

Section 83(b) election means you choose to include the bargain element in gross income at transfer instead of waiting for vesting under Section 83(a). The election is irrevocable once valid—model downside (forfeiture, company failure) before you mail.

Official filing package (what the IRS expects)

Treasury Regulation §1.83-2 and IRS Form 15620 align on the same factual disclosures. As of the April 2025 Form 15620 revision, the Service publishes a structured form; you may instead file a written statement that meets the regulation if every required fact is present.¹

Required contents (check against Form 15620 boxes)

Critical Warning: FMV must match your company’s 409A (private) or market price (public) methodology—Stock Administration and your CPA should sign off on the number before you ink the election.

Model language (Form 15620–aligned)

The IRS does not require magic words beyond electing under §83(b) and supplying the facts above. Practitioners often mirror Form 15620 so examiners see a familiar layout. Below is illustrative narrative structure—do not file without customizing numbers and names.

Where to mail (IRS service center addresses)

Form 15620 instructions (April 2025) direct you to mail the completed election to the IRS office with which the person who performs the services files a federal income tax return.³ That means your Form 1040 “Where To File” address for the active tax year—not a random “Austin TX” meme from an old blog post.

Original research: tech-employee state → IRS campus (Form 1040, no payment enclosed)

Methodology: On 21 May 2026, we pulled the IRS “Where to file paper tax returns” tables for calendar year 2025 individual Form 1040 returns without an enclosed payment, for states that dominate U.S. tech equity grants. We normalized city/ZIP to three campuses. Always re-verify before sealing the envelope—IRS tables change.

Envelope addressing tips:

Where I'm less sure—international addresses, ITIN-only filers, and military statuses sometimes route to specialized campuses; a one-line cover letter prepared by counsel beats guessing.

The 30-day deadline (official timing rules)

Use the 83(b) deadline & mailing tracker to compute last filing day and a mail-by buffer—we still recommend filing by day 25 when possible.

Certified Mail compliance (proof, not a deadline extender)

Certified Mail does not extend the 30-day substantive window—it creates third-party evidence that USPS accepted your envelope on a particular date. That matters because IRC §7502 can, in qualifying U.S. Postal Service mailings, treat a timely postmark as timely filing even if IRS processing arrives later—fact patterns get litigated; do not treat social media as authority.⁵

Post office script (copy/paste)

# At USPS counter (illustrative — confirm fees at post office, May 2026)
# 1. Place signed original election + optional cover sheet in envelope
# 2. Request "Certified Mail" + "Return Receipt" (electronic PDF if offered)
# 3. Keep PS Form 3800 receipt; photograph envelope with label visible
# 4. Export tracking PDF same day; store with duplicate signed PDF

Worked example: Priya, early exercise at Databricks (illustrative)

Facts (hypothetical, rounded): Priya is a senior software engineer in California. On 3 March 2026, she early-exercises 40,000 ISOs; the company issues 40,000 unvested common shares the same day. Stock Admin confirms Section 83 transfer date = 3 March 2026. 409A FMV = $4.10/share; exercise price = $0.42/share.

Verdict for Priya: File official Form 15620 language—do not rely on a random Notion template. If she misses 2 April 2026 postmark (with §7503 adjustment if applicable), she should assume no §83(b) for that transfer and call counsel immediately—AMT and withholding surprises compound fast after early exercise.

Steel-man: “I can DIY the official filing in an afternoon”

Best case for DIY: You have a single grant, Stock Admin already sent a company-approved 83(b) packet, FMV is trivial (nominal par value), and you are 10+ days before the deadline. Certified Mail plus Form 15620 is mechanically simple; the IRS really does process these every day.

Where DIY breaks: Multi-state moves mid-window, ITIN issuance, divorce community-property quirks, or underpayment penalties when accelerating $100k+ of phantom income. Anecdotally, the expensive mistakes we see in forums are wrong transfer dates and wrong campuses—not missing signature lines.

Our position: DIY mailing is fine for straightforward restricted stock grants if a CPA reviews FMV and restrictions first. Spend professional fees when the bargain element exceeds roughly $25,000 or when ISO/AMT interacts with early exercise—choose counsel over another hour of Reddit.

Verdict

For employees searching official filing instructions: treat Form 15620 + correct IRS campus + Certified Mail proof + employer copy as the non-negotiable bundle. File early in the window, verify addresses on IRS.gov for the active tax year, and escalate to a tax attorney when you are on day 28–30 or when accelerated income exceeds your cash on hand. Strategy without execution is worthless; execution without FMV validation is dangerous.
