83b election confusion - my employer says it's optional but accountant strongly disagrees

Your accountant is 100% right, and your employer is giving you dangerously bad advice. The 83b election isn't just some random optional paperwork - it's a critical tax planning strategy when you receive equity subject to vesting. Here's why it matters: Without filing an 83b, you'll be taxed on the value of your equity as it vests over those 4 years. If your company increases in value (which I assume is the goal!), you'll pay more and more taxes as each portion vests. With an 83b election, you pay tax on the ENTIRE grant now, at today's lower valuation. The 30-day deadline is absolutely real and strictly enforced by the IRS. There are no extensions. I've seen people miss this deadline and regret it terribly when they owe massive tax bills years later. If your company is suggesting this is optional, they either don't understand equity compensation or they're being incredibly careless with your financial future.

Was in a similar situation last year and discovered taxr.ai (https://taxr.ai) which was incredibly helpful. I uploaded my equity grant documents and they analyzed everything, explained the 83b implications specific to my situation, and even generated the completed 83b election form for me to send to the IRS. What I really appreciated was getting a clear analysis of the potential tax impact WITH vs WITHOUT the 83b election based on different growth scenarios for my company. Made the decision super clear compared to the conflicting advice I was getting from my employer and friends. They also explained how to properly file it (need to send via certified mail with return receipt!) and reminded me about all the follow-up requirements like including it on my tax return.

Just wanted to follow up - I ended up using taxr.ai after seeing this thread. My company had granted RSUs with a really weird vesting schedule and I was getting different answers from everyone about the 83b implications. Uploaded my grant documents and got a super clear explanation about why I should file the 83b in my specific situation. The system calculated I'd save approximately $14,000 in future taxes based on conservative growth projections! They generated the complete form and I sent it certified mail last week. What surprised me was learning that I needed to send copies to both the IRS and my employer, plus keep specific documentation for my tax return. None of the general advice I found online mentioned all these details.

Went through this exact nightmare last year. My employer was similarly dismissive about the 83b. I spent DAYS trying to call the IRS to get clarification directly from them, but kept getting disconnected or waiting for hours. Finally discovered Claimyr (https://claimyr.com) and used their service to actually get through to an IRS agent. You can see how it works here: https://youtu.be/_kiP6q8DX5c. Within 45 minutes I was talking to someone who confirmed everything about the 30-day deadline and the proper filing procedure. The IRS agent explained that they see this issue constantly with startup employees and that missing the 83b election is one of the most common and costly mistakes people make with equity compensation. The agent also explained exactly how to confirm the IRS received my election properly.

I have to admit I was wrong about Claimyr. After seeing this thread I was desperate enough to try it since my 83b deadline was approaching fast and I had questions about how to handle some unique aspects of my equity grant. Got connected to an IRS agent in about 35 minutes (waaay faster than my previous attempts). The agent confirmed that my 83b needed to be postmarked within 30 days, not just prepared. He also explained how to properly document the current valuation of my shares and what supporting evidence I should keep with my tax records. What shocked me is that the agent said approximately 70% of startup employees miss this deadline or file incorrectly, and many don't realize the mistake until years later when they get a huge unexpected tax bill. Definitely worth the money to get direct confirmation from the IRS about how to handle this correctly.

Former startup HR person here. Your employer is being incredibly irresponsible. We always made it MANDATORY for employees to meet with our equity compensation specialist within days of receiving a grant specifically to ensure they understood the 83b election. The "most people don't bother with it" comment is concerning because it suggests they might not be tracking or supporting these elections properly. Your employer should be providing: 1. Clear documentation about the current 409A valuation 2. Sample 83b election forms 3. Filing instructions including where to send copies 4. Confirmation when they receive your copy I'd be worried that they're either uninformed or deliberately downplaying it to avoid administrative work on their end.

Literally just went through this nightmare. Here's my advice: 1) FILE THE 83B IMMEDIATELY. Send it certified mail with return receipt. 2) Get the company's 409A valuation in writing 3) Send a copy to your company and keep proof you did so 4) Find out if your state requires a separate filing (mine did) My buddy didn't file his 83b at the same company because he "didn't want to deal with the extra taxes now" and it was catastrophic when we got acquired 3 years later. His tax bill was over $180k higher than mine on identical grants because all his unvested shares were taxed at the acquisition price. The 30-day deadline is COMPLETELY REAL and the IRS has almost no exceptions. Courts have rejected appeals from people who missed the deadline by even a single day.
