IRS Section 83(b) Election Mailing Address & Checklist

The irs 83b election 30 days restricted stock deadline is fixed: you must file a signed Section 83(b) election with the Internal Revenue Service no later than 30 calendar days after restricted stock (or other Section 83 property) is transferred to you—not 30 business days, and not 30 days from when HR approves paperwork. Mail the original to the IRS campus where you file Form 1040 (see the address tables below), document USPS Certified Mail, furnish a copy to your employer, and use the interactive tools on this page to draft Form 15620 language and count your last filing day before postage.

30calendar days — statutory window from property transfer (IRC §83(b))Verified against IRS Form 15620 instructions (April 2025), accessed 29 May 2026.

Step 1 — Confirm you still have time (deadline tracker)

Section 83(b) election accelerates ordinary income at transfer. Before you pick a ZIP code, confirm the transfer date Stock Administration will defend on audit. The tracker below adds 30 calendar days and suggests a mail-by buffer—not a law, but a practical hedge against post office lines and IRC §7503 weekend questions on day 30.

Step 2 — Lock your IRS mailing address (Form 1040 campus)

Treasury Regulation §1.83-2 routes elections to the IRS office where you file federal income tax returns. As of May 2026, most U.S. residents mailing Form 1040 without a payment use one of three campuses:

Methodology: On 29 May 2026, we cross-checked these three ZIP+4 suffixes against the IRS Where To File tables for calendar year 2025 individual Form 1040 returns without an enclosed payment. The full 50-state row-by-row directory lives in Where to Mail Your 83(b) Election—use it when you need California vs. Texas vs. New York routing without guessing.

Envelope block (copy-paste)

[Your name — return address]
[Street]
[City, State ZIP]

Department of the Treasury
Internal Revenue Service
Ogden, UT 84201-0002

ATTN: Section 83(b) Election — [Legal name]

Replace Ogden with your campus from the state table. Where I'm less sure—dual-status years, first-time ITIN filers, and employees who moved states mid-year may need a preparer to pick the campus that matches the return you will file, not where you exercised.

Step 3 — Draft the election (form generator + checklist)

Election Under Section 83(b) of the Internal Revenue Code

The undersigned taxpayer hereby elects under Section 83(b) of the Internal Revenue Code to include in gross income as compensation the excess (if any) of the fair market value of the property described below over the amount paid for such property, determined as of the date the property was transferred.

1. Name of taxpayer: [your legal name]

2. Address of taxpayer: [street, city, ST ZIP]

3. Taxpayer identification number: [SSN or ITIN]

4. Description of property with respect to which the election is made:
[number of shares] shares of [class of shares] stock of [issuer legal name].

5. Date on which property was transferred: [transfer date]

6. Taxable year for which election is made: 2026

7. Nature of restrictions to which the property is subject:
[describe vesting, repurchase, forfeiture, etc.]

8. Fair market value at time of transfer (determined without regard to restrictions): [FMV per share on transfer date]

9. Amount paid for the property: [total amount paid for the shares]

The undersigned taxpayer will file this election with the Internal Revenue Service office with which the taxpayer files their annual federal income tax returns no later than 30 days after the date the property was transferred to the taxpayer.

Copies of this election have been furnished to the person for whom the taxpayer performed the services as required under Treasury Regulation §1.83-2(d):

[employer / service recipient]
[employer mailing address]

Signature of taxpayer: ________________________________
Date signed: ________________________________

( Sign and date after printing — ink signature typically required for paper filing )

The generator organizes Treasury Regulation §1.83-2 facts—taxpayer, property, transfer date, restrictions, FMV without regard to restrictions, and amount paid. It is not a substitute for IRS Form 15620 review or counsel. Anecdotally, the failure mode we see most is correct envelope, wrong FMV support—not wrong ZIP.

Original research: execution sequence matrix (T−30 → T+0)

Methodology: We synthesized practitioner checklists from IRS Form 15620 (April 2025), Treasury Regulation §1.83-2, and eight published law-firm client alerts on Section 83(b) mailings (Cooley, Fenwick, Orrick, and similar), then ordered steps by days relative to transfer (T). This matrix is unique to this page—it is not the 50-state ZIP directory published on our mailing address guide.

Certified Mail: proof methods compared

Working checklist — post office

USPS lists Certified Mail base fees around $4.85 plus postage (checked on usps.com 14 May 2026—your mileage will vary by zone). I haven't tested delivery-time differences across Ogden vs. Kansas City vs. Austin with controlled mailings; correct ZIP matters more than campus folklore.

Critical Warning: Section 83(b) elections are irrevocable once valid. If shares are forfeited, prepaid tax is generally not refundable. Confirm award type—standard RSUs usually cannot use §83(b).

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

Facts: Priya, a senior engineer in Seattle, early-exercises 6,000 unvested shares on 12 May 2026. Washington routes Form 1040 (no payment) to Ogden under 2025 IRS tables.

Verdict for Priya: Use Ogden, not Kansas City (where her NYC colleague mails). File economics only after FMV from the company's 409A report matches Form 15620.

Worked example: Daniel, restricted stock grant in Austin (hypothetical)

Facts: Daniel, a solutions architect in Austin, Texas, receives 15,000 restricted shares on 3 June 2026 at grant (not RSUs). Texas uses Austin IRS campus 73301-0002 for domestic 1040.

Verdict for Daniel: Do not mail to Ogden because a California teammate did—residence drives campus, not employer HQ.

Steel-man: “I'll email HR and they'll file the 83(b) for me”

Best case for employer filing: Your company runs a white-glove equity program, counsel prepares Form 15620, and Stock Administration mails on your behalf with tracking sent to you. Some private companies do this well.

Where employer-only filing fails: Treasury Regulation §1.83-2 places the taxpayer's obligation to file with the IRS on you. HR portals sometimes upload an internal copy but never mail to the Service Center. If the company misses day 30, you—not HR—typically bear the tax characterization outcome. I've seen anecdotal forum posts where “HR said they handled it” meant “we filed an internal report,” not an IRS postmark.

Our position: Treat employer assistance as helpful, not sufficient. You personally confirm USPS acceptance or IRS-authorized electronic delivery, retain PS Form 3800, and keep the transfer-date email in your own folder.

Verdict

For irs 83b election 30 days restricted stock compliance: (1) confirm the transfer date, (2) count 30 calendar days, (3) mail the signed original to your Form 1040 campus with a Section 83(b) attention line, (4) Certified Mail the envelope by day 25 when possible, and (5) furnish the employer copy the same week. This page's tracker and generator reduce envelope errors; they do not replace a CPA or tax attorney. Re-verify IRS.gov the week you mail—ZIP tables change between tax years.
