83(b) Election Step-by-Step Filing Guide: How to File in 30 Days

Why This 30-Day Deadline Could Save You $50,000 (Or Cost You If You Miss It)

Sarah joined a startup in January and received 40,000 shares of restricted stock worth $0.10 per share. That's $4,000 total. She had a choice to make within 30 days, and that choice would determine whether she paid $3,000 in taxes or $148,000.

Here's what happened in each scenario:

Path 1: Sarah files an 83(b) election within 30 days

• She pays tax on $4,000 (the current value) = roughly $1,200 in taxes
• Four years later when her shares vest, they're worth $10 each ($400,000 total)
• She pays zero additional ordinary income tax at vesting
• When she eventually sells, she only pays capital gains tax on the profit
• Total ordinary income tax: $1,200

Path 2: Sarah misses the 30-day deadline

• She pays nothing upfront
• Four years later when her shares vest at $10 each
• The IRS treats $400,000 as ordinary income (taxed like her salary)
• She owes roughly $148,000 in taxes at the 37% rate
• Total ordinary income tax: $148,000

Think of the 83(b) election like locking in concert ticket prices. File within 30 days and you pay tax based on today's low price. Miss the deadline and you pay tax based on whatever the price is when your shares vest, which could be 100x higher.

The 30-day deadline isn't flexible. There are no extensions. The IRS doesn't care if you were busy or didn't know. Miss it by one day and you've lost the opportunity forever.

Let's make sure you know exactly how to file correctly.

What Is an 83(b) Election? (The 2-Minute Explanation)

An 83(b) election is a form you file with the IRS that says "I want to pay taxes on my restricted stock right now, based on today's value, instead of waiting until it vests."

Think of it like buying a house you can't sell for 4 years. You can choose to pay property taxes based on what the house is worth today, or wait and pay taxes based on what it's worth in 4 years when you can finally sell it. If the neighborhood booms and your house doubles in value, you'll wish you'd locked in the lower tax bill early.

Here's Why the IRS Allows This

The government gets tax money sooner. You get potential savings if your stock value grows. It's a trade-off both sides accept.

The Basic Math (This Is Where It Gets Real)

You receive $10,000 worth of restricted stock today. It vests over 4 years. You're in the 37% tax bracket.

Without an 83(b) election: You pay nothing today. But when the stock vests and is worth $100,000, you owe taxes on $100,000. That's roughly $37,000 in taxes.

With an 83(b) election: You pay tax on $10,000 today. That's roughly $3,700 in taxes. When it vests at $100,000, you owe nothing more (until you sell).

Your savings: $33,300.

The Catch (There's Always a Catch)

If the stock becomes worthless or you leave before it vests, you already paid that $3,700. The IRS doesn't give refunds on 83(b) elections. This choice is permanent and irrevocable.

What Type of Stock Does This Apply To?

This only works with restricted stock (actual shares you receive but can't sell yet). It does not apply to RSUs, ISOs, or NSOs. Those follow different tax rules.

Now that you understand what an 83(b) election is, let's figure out if you actually need to file one.

Do You Actually Need to File? (Quick Eligibility Check)

Before you spend time filing an 83(b) election, let's figure out if you even need one. Think of it like a library card: you only apply if you actually want to check out books. Similarly, you only file an 83(b) if you have the specific type of equity that qualifies.

The Simple 3-Question Test

Answer these three questions:

1. Did you receive restricted stock (actual shares, not RSUs)? If no, stop here. You can't file an 83(b).
2. Is it subject to vesting? (Will you lose it if you leave before a certain date?) If no, you don't need an 83(b).
3. Did you pay less than what it's worth today? If no, there's no tax benefit to filing.

If you answered yes to all three, keep reading. You likely need to file.

What Types of Equity Qualify?

Here's the breakdown:

The key requirement: Your stock must have a "substantial risk of forfeiture." In plain English, this means you'll lose it if you leave the company before it vests. That's what makes the 83(b) election necessary.

Real Examples: Who Files and Who Doesn't

Marcus (Startup Founder) - NEEDS to file: Marcus co-founded a startup and received 1,000,000 shares that vest over 4 years. He paid $0.001 per share ($1,000 total), but they're currently worth $0.10 per share ($100,000 fair market value). If he doesn't file an 83(b), he'll owe taxes on $25,000 each year as shares vest. With an 83(b) election, he pays taxes on $99,000 ($100,000 - $1,000) today, which could save him tens of thousands later.

Jessica (Public Company Employee) - CANNOT file: Jessica works at Google and received 100 RSUs worth $15,000. She wants to file an 83(b) to lock in today's value. Unfortunately, RSUs don't qualify. She doesn't actually own stock until the RSUs vest, so there's nothing to file an election on.

Common Scenarios Where You DO Need This

You're most likely to need an 83(b) if you're:

• A startup founder with stock subject to vesting
• An early employee (first 10-20 people) who bought restricted stock
• An executive who negotiated a restricted stock package
• Someone who early exercised stock options before they vested

If you're a regular employee at a public company getting RSUs as part of your compensation package, you cannot file an 83(b). Those are different animals entirely.

Now that you know whether you need to file, let's gather everything you'll need to complete the process.

Before You Start: What You Need to Gather (5-Minute Prep)

Think of filing your 83(b) election like packing for a trip. You want everything in one place before you start, so you're not scrambling to find your passport while the taxi's waiting.

Here's your complete checklist. Grab these now, and filling out the form will take 10 minutes instead of an hour.

Your Personal Information

☐ Full legal name (as it appears on your tax return) ☐ Home address (where you lived when you got the stock) ☐ Social Security Number (from your W-2 or tax return)

Your Company's Information

☐ Company's full legal name (check your grant agreement, it might be "Acme Corporation" not just "Acme") ☐ Company's EIN (Employer Identification Number, like a Social Security Number for businesses)

Where to find the EIN: Email your HR or finance team. Say "I need the company EIN for my 83(b) election." They'll know what you mean. It's a 9-digit number like 12-3456789.

Your Stock Details

☐ Grant date (the day you actually got the stock, not the day you signed your offer letter) ☐ Number of shares (like 50,000 shares) ☐ Type of stock (usually "restricted common stock") ☐ Vesting schedule (like "4 years, 25% each year")

Where to find this: Log into your company's equity portal (Carta, Shareworks, E*TRADE, etc.). Look for "Grant Details" or "Equity Summary." You can also find it in your grant agreement.

The Money Details

☐ What you paid per share (your "purchase price," often $0.01 or $0.10) ☐ Total amount you paid (shares × price per share) ☐ Fair Market Value (FMV) per share on grant date

Critical note about FMV: You MUST get this from your company. Don't guess. Email HR or finance and say: "I need the 409A valuation price per share as of [your grant date] for my 83(b) election." They're required to provide this. It comes from a formal valuation report.

Your Grant Agreement Document

☐ The actual grant agreement (keep this open for reference)

Where to find it: Check your email for "stock grant" or "equity award." It's also usually in your equity portal under "Documents." You signed this when you got your stock, either electronically or on paper.

Real Example: David's 5-Minute Prep

David got his stock grant on January 15, 2024. Here's what he gathered:

Personal info: Already knew his name, address, and SSN.

Company info: Found the company's legal name on his grant agreement: "Rocket Labs, Inc." Emailed HR for the EIN, got it in 2 hours: 94-1234567.

Stock details: Logged into Carta and found:

• Grant date: January 15, 2024
• 50,000 shares of restricted common stock
• 4-year vesting, 25% per year
• He paid $0.01/share = $500 total

FMV: Emailed finance: "Need the 409A FMV per share for January 15, 2024." They replied: $0.25/share (from the company's December 2023 409A valuation).

Total prep time: 5 minutes of looking things up, plus waiting for two emails.

Now David has everything. He won't need to stop halfway through the form to hunt for information.

---

Once you've gathered everything on this checklist, you're ready to fill out the actual form. The next section walks you through it line by line, so you'll know exactly what to write in each box.

Step 1: Fill Out the 83(b) Election Form (Line-by-Line Instructions)

Think of the 83(b) form like filling out a job application. Each line asks for specific information, and we'll walk through it together. The form is only one page, and most of it is just copying numbers from your stock grant paperwork.

You can download the blank form by searching "IRS 83(b) election form" or asking your company's equity team. It's not an official IRS form with a number (like a W-2), so any version that includes the required information works. It's not an official IRS form with a number (like a W-2), so any version that includes the required information works.

The Header Section: Your Basic Info

What they want: Your name, address, and Social Security Number.

What to write: Use your full legal name exactly as it appears on your tax return. Include your current mailing address and SSN.

Example: Sarah Chen, 123 Main Street, San Francisco, CA 94102, SSN: 123-45-6789

Section 1: Description of Property

What they want: What kind of stock you're getting.

What to write: "[Number] shares of [Company Name] common stock"

Example: "40,000 shares of TechStartup Inc. common stock"

This is the total number of shares you were granted, not just the vested amount. Find this number on your stock grant agreement.

Section 2: Date Property Transferred

What they want: When you got the stock.

What to write: The grant date from your paperwork.

Example: January 15, 2024

This is not your hire date or the date you signed paperwork. It's the official date the company granted you the shares.

Section 3: Taxable Year

What they want: What tax year this applies to.

What to write: The year from Section 2.

Example: 2024

Section 4: Nature of Restrictions

What they want: Your vesting schedule in plain English.

What to write: "Shares vest over [time period] with [schedule details]"

Example: "Shares vest over 4 years: 25% after 1 year, then monthly over the remaining 36 months"

Copy this language from your grant agreement. Don't overthink it. The IRS just wants to know the shares don't fully belong to you yet.

Section 5: Fair Market Value

What they want: Total value of all shares at today's price.

What to write: Price per share × total shares = total FMV

Example: $0.10 per share × 40,000 shares = $4,000

Your company tells you the FMV (also called "409A valuation"). It's usually in your grant paperwork or available from HR.

Section 6: Amount Paid

What they want: What you actually paid for the shares.

What to write: Your exercise price × total shares = total paid

Example: $0.01 per share × 40,000 shares = $400

For restricted stock, this is often a very small number or even zero. That's normal.

Section 7: The Math (Amount Included in Income)

What they want: Section 5 minus Section 6.

What to write: FMV - Amount Paid = Taxable Amount

Example: $4,000 - $400 = $3,600

This $3,600 is the amount Sarah will pay ordinary income tax on right now. It's like getting a $3,600 bonus. She'll owe roughly $1,000-$1,400 in taxes depending on her tax bracket.

Sign and Date

Sign your legal name and write today's date. That's it.

Important: Don't leave any section blank. If something doesn't apply, write "N/A" or "None." The IRS can reject incomplete forms.

Now that your form is filled out, you need to make copies before mailing anything. That's our next step.

Step 2: Make Copies and Prepare Your Filing Package (The 3-Copy Rule)

Think of this like sending wedding invitations. The venue needs one, the caterer needs one, and you keep one for your records. Everyone gets their own copy.

You need three identical copies of your signed 83(b) form. Here's exactly what to do with each one:

Copy 1: IRS

• This goes in the mail with certified tracking (we'll cover exactly how in the next section)
• Must arrive within 30 days of your grant date

Copy 2: Your Company

• Usually goes to HR, finance, or your stock plan administrator
• Send via email with a simple note: "Please find my 83(b) election attached"
• Some companies have a specific process, so ask if you're unsure

Copy 3: Your Personal Records

• This stays with you forever
• File it with your important tax documents
• You'll need it when you sell your shares years from now

Critical step: Sign all three copies in blue or black ink. Yes, even the copy for your records. Your signature proves these are original documents, not later photocopies.

Pro tip: Before you mail or send anything, scan all three signed copies and save the PDFs. Name the file "83b_Election_[YourName]_[Date].pdf" so you can find it easily. Email it to yourself too. Digital backups have saved people thousands when paper copies go missing.

Example: Maria fills out her 83(b) form on January 20th (5 days after her grant date). She makes 3 copies, signs all of them, and scans them to her computer. She puts Copy 1 in an envelope for the IRS, emails Copy 2 to her company's HR with a note saying "Please find my 83(b) election attached," and puts Copy 3 in her "Important Tax Documents" folder at home.

Now you're ready to mail Copy 1 to the IRS. This next step is where most mistakes happen, so pay close attention.

Step 3: Mail to the IRS the Right Way (Certified Mail Is Non-Negotiable)

You wouldn't mail a signed contract to buy a house with a regular stamp and hope it arrives. Your 83(b) election deserves the same level of care. This is where many people mess up, not because the process is hard, but because they cut corners on proof.

Why certified mail matters: When the IRS says they never received your form (and yes, this happens), certified mail with return receipt is your only defense. That little green card that comes back with a signature is worth its weight in gold. Without it, you have no proof, and the IRS won't accept "but I mailed it" as evidence.

Find Your IRS Service Center Address

The IRS address you use depends on where you live. You can't just mail it to "IRS Headquarters" and hope for the best.

IRS Service Center Addresses for 83(b) Elections:

• If you live in: Connecticut, Delaware, District of Columbia, Georgia, Illinois, Indiana, Kentucky, Maine, Maryland, Massachusetts, Michigan, New Hampshire, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Rhode Island, South Carolina, Tennessee, Vermont, Virginia, West Virginia, Wisconsin

• Mail to: Internal Revenue Service, Stop 824G, 7940 Kentucky Drive, Florence, KY 41042

• If you live in: Alabama, Alaska, Arizona, Arkansas, California, Colorado, Florida, Hawaii, Idaho, Iowa, Kansas, Louisiana, Minnesota, Mississippi, Missouri, Montana, Nebraska, Nevada, New Mexico, North Dakota, Oklahoma, Oregon, South Dakota, Texas, Utah, Washington, Wyoming

• Mail to: Internal Revenue Service, Stop 824G, 7940 Kentucky Drive, Florence, KY 41042

Note: As of 2024, most 83(b) elections go to the Florence, KY center. Check IRS.gov for the most current address, as these occasionally change.

The Step-by-Step Mailing Process

Step 1: Prepare your envelope

• Use a standard business envelope
• Write "Section 83(b) Election" on the outside (this helps IRS routing)
• Address it to the IRS service center for your region
• Include your return address

Step 2: Go to the post office (don't use the drop box)

• Bring your sealed envelope
• Ask for "Certified Mail with Return Receipt Requested"
• The clerk will give you a green card (PS Form 3811) to fill out
• Write your address as the return address on the green card

Step 3: Pay and get your receipts

• Cost: approximately $8 to $10 total
• You'll get a receipt with a tracking number starting with "PS 7000..."
• Keep this receipt in a safe place

Step 4: Track and save proof

• Track your letter at usps.com using your tracking number
• In 1 to 3 weeks, the green return receipt card comes back to you
• This card has the IRS signature and delivery date
• Keep this card forever (seriously, staple it to your tax records)

Real Example: Jake's Filing

Jake's grant date was February 1st. On February 15th (14 days later, well within the 30-day window), he goes to his local post office.

He brings an envelope addressed to:

Internal Revenue Service
Stop 824G
7940 Kentucky Drive
Florence, KY 41042

ATTN: Section 83(b) Election

He asks the postal clerk for Certified Mail with Return Receipt Requested. He pays $9.50 and gets:

• A receipt with tracking number PS 7000 0000 0000 0000 0000
• A green return receipt card to fill out

Two weeks later, the green card arrives in his mailbox with an IRS employee's signature and the date "February 17, 2024." This proves the IRS received his election on day 16 after his grant date. He staples this card to his copy of the 83(b) form and files it with his important tax documents.

Alternative: Private Delivery Services

You can also use FedEx, UPS, or DHL, but only specific services qualify:

• FedEx Priority Overnight, Standard Overnight, or 2Day
• UPS Next Day Air, Next Day Air Saver, 2nd Day Air, or 2nd Day Air A.M.
• DHL Express 9:00, 10:30, 12:00, or Worldwide Express

These services automatically include tracking, which serves as your proof of delivery. Cost: $25 to $50, depending on the service.

What NOT to Do

Don't email or fax. The IRS doesn't accept 83(b) elections electronically. There's no online portal, no email address, no fax number. Mail only.

Don't hand-deliver to your local IRS office. They can't accept it there. It must go through the service center.

Don't use regular mail without tracking. You're gambling your tax savings on the postal service with zero proof of delivery.

The Postmark Is What Counts

Remember, the IRS cares about the postmark date, not when they actually receive it. If your grant date was February 1st, your envelope must be postmarked by March 2nd (day 30). If the post office stamps it March 2nd but the IRS doesn't open it until March 10th, you're fine.

This is why going to the post office counter matters. The clerk stamps it right in front of you. If you drop it in a mailbox, you're trusting that it gets picked up and postmarked the same day.

---

Once the IRS has your election, you're not done yet. Your company needs a copy too, and there's a specific way to submit it to them.

Step 4: Submit a Copy to Your Company (And Why They Need It)

Think of this like notifying your landlord when you move out. They need to know so they can update their records and handle their paperwork correctly. Same deal here.

You must send a copy of your signed 83(b) election to your company within the same 30-day window. This is a legal requirement, not a courtesy.

Who to Send It To

Most companies want you to send it to one of these:

• HR department (most common)
• Finance or accounting team
• Stock plan administrator (if your company has one)

Check your stock grant paperwork or employee portal. It usually says where to send tax forms. If you're not sure, start with HR.

How to Deliver It

You have three options:

1. Email (easiest): Send a PDF of your signed form
2. Company equity portal: Some companies have an upload feature
3. Hard copy: Hand deliver or mail to your HR office

Email works 95% of the time. Keep it simple.

Copy This Email Template

Subject: 83(b) Election for Restricted Stock Grant

Hi [HR contact name],

I've filed an 83(b) election for the restricted stock granted to me on [grant date]. Please find a signed copy attached for the company's records.

Let me know if you need anything else.

Thanks,
[Your name]

Example: Carlos sends this email to [email protected] on January 10, the same day he mails his form to the IRS. He attaches the PDF of his signed 83(b) election. HR replies within two days confirming they received it.

Why Your Company Needs This

Your company uses your 83(b) election for two things:

1. Tax withholding: They need to withhold income tax on the value you claimed (usually $0 or very low)
2. W-2 reporting: They report this income on your W-2 at tax time

Without your 83(b) copy, they'll report income incorrectly when your stock vests. That creates a tax mess you'll have to untangle later.

Get Confirmation

Always get proof they received it. Save the email reply or take a screenshot of any confirmation number. This protects you if there's ever a question about whether you filed properly.

If you don't hear back within a week, follow up. A quick "Hey, just checking you got my 83(b) election?" works fine.

Now that the IRS and your company both have copies, you have one final step to complete at tax time.

Step 5: File With Your Tax Return (The Often-Forgotten Final Step)

You mailed your 83(b) election to the IRS. You gave a copy to your company. You're done, right?

Not quite. There's one more step that trips up almost everyone.

Think of it like submitting a doctor's note with an insurance claim. The main claim goes to the insurance company right away. But when you file your annual paperwork, you need to attach that doctor's note again as backup. Same deal with your 83(b) election.

You Need to Attach It to Your Tax Return

When you file your tax return for the year you received the stock, you must attach a copy of your 83(b) election form.

Here's how the timing works:

• Stock granted in January 2024? Attach the 83(b) to your 2024 tax return (filed in April 2025).
• Stock granted in December 2024? Still attach it to your 2024 return.
• Filed an extension until October? Attach it then.

This is in addition to the copy you already mailed to the IRS within 30 days. You're not replacing that step. You're adding this one.

Where Exactly to Attach It

If you're filing on paper: Staple a copy of your 83(b) election to the back of your Form 1040.

If you're filing electronically: Most tax software lets you upload PDFs as attachments. If your software doesn't allow attachments, mail a paper copy to the IRS separately with a note: "83(b) election for 2024 tax return, filed electronically on [date]."

Don't Forget to Report the Income

Your 83(b) election created taxable income. You need to report that amount on your tax return.

Look at Section 7 of your 83(b) form. That's the number you need (fair market value minus what you paid).

Real example: Alicia filed her 83(b) election in January 2024 for startup stock. She paid $1,000 for shares worth $6,000. Her 83(b) form showed $5,000 of income in Section 7.

In April 2025, when she files her 2024 tax return, she:

1. Reports $5,000 as "other income" on her Form 1040
2. Attaches a copy of her 83(b) election form
3. Pays tax on that $5,000 (about $1,850 in her 24% tax bracket)

She uses TurboTax and uploads the 83(b) PDF as an attachment when prompted for supporting documents.

What If You Forget This Step?

The IRS won't reject your 83(b) election if you forget to attach it to your tax return. Your original mailed copy (from Step 3) is what counts for the 30-day deadline.

But the IRS wants to see it with your return. If you forget, you might get questions later when you sell the stock and report capital gains.

Bottom line: Just attach it. It takes 30 seconds and saves potential headaches.

Quick Note on Tax Software

Most tax software has a section for "restricted stock" or "other income from equity compensation." Follow those prompts and enter your $5,000 (or whatever your number is).

The software will ask if you made an 83(b) election. Say yes. Then upload your form as a PDF attachment.

If you're working with a tax preparer, just hand them your 83(b) copy. They'll know what to do.

---

Now that you know all five filing steps, let's talk about the worst-case scenario: what happens if you miss that 30-day deadline?

What Happens If You Miss the 30-Day Deadline? (And Can You Fix It?)

Missing the 83(b) deadline is like missing your flight after the gate door closes. Once it's shut, you're not getting on that plane. There's no extension, no late filing, and no exceptions (with one rare case we'll cover below).

The harsh reality: If you miss the 30-day deadline, you cannot file an 83(b) election for that stock grant. Period.

What This Means for Your Taxes

Without an 83(b) election, you'll pay ordinary income tax on the full fair market value of your shares when they vest, not when you received them.

Here's what that looks like in real numbers:

Tom's Story: Tom received 1,000 shares of restricted stock on March 1st. The stock was worth $10 per share ($10,000 total). He planned to file his 83(b) election but forgot. On March 31st (day 30), he remembered, but it was too late.

Tom's stock vests 25% per year over four years. Here's what happens:

• Year 1: 250 shares vest at $30/share = $7,500 taxable income
• Year 2: 250 shares vest at $50/share = $12,500 taxable income
• Year 3: 250 shares vest at $70/share = $17,500 taxable income
• Year 4: 250 shares vest at $100/share = $25,000 taxable income

Total tax bill: Tom pays taxes on $62,500 of income (at his ordinary income tax rate of 35%, that's $21,875 in taxes).

If he'd filed the 83(b): He would have paid tax on just $10,000 upfront ($3,500 in taxes). He missed out on $18,375 in tax savings.

The One Narrow Exception

There is exactly one way to undo an 83(b) election, but it doesn't help if you forgot to file.

You can revoke an 83(b) election within 60 days if there was a "mistake of fact." This means you genuinely misunderstood a key fact about the stock (like the number of shares or the vesting schedule). It does NOT mean "I forgot to file" or "I changed my mind."

This exception is extremely rare and requires proof. Don't count on it.

What You're NOT Losing

Missing the deadline doesn't affect your ownership of the stock. You still own the shares. They still vest on schedule. You just pay taxes differently (and usually pay more).

What to Do If You Missed It

Accept that you can't fix this particular grant. Here's what you CAN do:

1. Plan for tax payments at each vesting date Set aside money to cover the tax bill each time shares vest. Calculate roughly 40% of the vested value (federal + state + FICA taxes).

2. Consider tax-loss harvesting later If the stock drops in value after vesting, you might be able to sell some shares at a loss to offset other gains.

3. Set reminders for future grants If you receive more restricted stock in the future, set a calendar alert for day 1, day 15, and day 25 after the grant date.

4. Talk to a tax professional They can help you plan for the tax hits and explore other strategies to minimize the damage.

The Bottom Line

The 30-day deadline is absolute. Miss it, and you'll pay significantly more in taxes over time. But you still own the stock, and with proper planning, you can manage the tax bills as they come.

Now that you understand the consequences of missing the deadline, let's look at some special situations that can complicate your 83(b) election, even if you file on time.

Special Situations: What Your HR Won't Tell You About 83(b) Elections

Think of the 83(b) election like reading the fine print on a contract. The basic terms are clear, but there are important details buried in the footnotes that can seriously affect you. Your company's HR team covers the basics, but they often skip the edge cases that matter most.

Here's what they don't always explain.

The AMT Trap: Early Exercised ISOs

Scenario: Nina's $14,000 Surprise

Nina early exercises 50,000 ISOs at $0.10 per share when the fair market value is $1.10. She files her 83(b) election. The spread is $50,000 ($1.10 - $0.10 × 50,000 shares).

Good news: She owes $0 in regular income tax because ISOs get special treatment.

Bad news: She triggers $14,000 in Alternative Minimum Tax (AMT).

AMT is like a parallel tax system that catches certain tax breaks. Even though ISOs normally don't create income tax, the spread between your exercise price and the fair market value counts for AMT purposes. The rate is typically 28%, so Nina owes $14,000 ($50,000 × 28%) that April.

The Forfeiture Risk: You Can't Get Your Tax Money Back

Scenario: Alex Loses $7,400

Alex receives 10,000 shares of restricted stock worth $2 each ($20,000 total). He files an 83(b) election and pays $7,400 in taxes (37% tax bracket). The stock vests over four years.

Eighteen months later, Alex leaves for a new job. Only 2,500 shares have vested. He forfeits the other 7,500 shares.

Here's the painful part: Alex paid $7,400 in taxes on stock he'll never own. The IRS doesn't give refunds when you forfeit unvested shares. That tax money is gone forever.

This is the biggest risk of filing an 83(b) election. You're betting you'll stay long enough to vest. If you leave early, you lose both the stock and the taxes you paid.

The Capital Gains Win: Why People File Despite the Risks

Scenario: Sarah Saves $110,000

Sarah filed an 83(b) election on restricted stock worth $4,000. She paid $1,480 in taxes upfront.

Five years later, she sells the stock for $500,000.

Because of her 83(b) election, all $496,000 of appreciation is taxed as long-term capital gains at 15%. She pays $74,400 in tax.

Without the 83(b) election, the appreciation would be ordinary income at 37%. She would have paid $183,520.

The 83(b) election saved her $109,120 in taxes. This is why people take the forfeiture risk.

State Tax Complications

California recognizes 83(b) elections. Many other states do too. But some states don't follow federal tax rules exactly.

Check your state's tax agency website or ask a local tax professional. You might need to file a separate state form. Don't assume your state automatically follows the federal election.

How It Shows Up on Your W-2

The income from your 83(b) election appears on your W-2 in the year you file. Your company should withhold taxes from your paycheck to cover it.

If you paid cash for the stock at fair market value, there's no income to report. But file the 83(b) election anyway. It creates a clear record that you owe no tax on the grant.

What If the 409A Valuation Was Wrong?

Companies determine fair market value using a 409A valuation. Sometimes these are conservative (too low).

If the IRS later decides the fair market value was actually higher, you might owe additional tax. This is rare, but it happens. You can't go back and change your 83(b) election.

When You're a Founder Paying Cash

If you're a founder who paid $1.00 per share and the fair market value is $1.00, you have no spread. There's zero income to report.

File the 83(b) election anyway. It documents that you paid fair market value and starts your capital gains holding period on day one. This gives you certainty and avoids questions later.

Time Investment vs. Potential Savings

What you'll spend: 2-3 hours total over 30 days

What you could save: $10,000 to $100,000+ in taxes, depending on how much your stock grows. Example: You receive 10,000 shares at $0.10 per share. If they grow to $10 per share at vesting, filing 83(b) saves you roughly $20,000 in federal taxes alone.
