Should you file an 83(b) election? The decision and the breakeven

Should you file an 83(b) election? If your restricted stock is worth almost nothing today, yes, in nearly every case. The hard version of this question only shows up later, when the shares already have a price and filing means writing a real check now for a bet that might not pay off.

So the honest answer is two answers, and which one you get depends entirely on what the stock is worth the day you decide.

The easy case: near-zero stock

Most early founder shares and the earliest employee restricted stock awards are granted when the company is worth almost nothing. You file the 83(b), report a trivial amount of income, and pay a tax bill that might be a few dollars. In exchange you flip all the future growth from ordinary income to capital gains and start your holding clock today.

The downside if you file and the company fails: you paid a few dollars in tax you did not get back. That is the entire risk. Set a few dollars of regret against a potential six-figure tax swing and the decision makes itself.

The hard case: the stock already has value

Now suppose the shares are worth real money at grant, maybe because you joined later or the valuation already climbed. Filing the 83(b) means paying ordinary income tax now on that value, in cash, out of pocket. If the company stumbles, you do not get that tax back. You paid real money to lock in a treatment that only pays off if the stock keeps rising.

This is where I see people file on autopilot because “everyone files the 83(b),” and it is exactly the spot where you should slow down. The election is a bet that the upside is large enough and likely enough to justify prepaying tax on today’s value. On near-zero stock that bet is free. On valued stock it is a real bet with a real cost.

The breakeven: where prepaying beats waiting

When does filing actually pay off? At almost any stock price above where you started, on cheap stock. The election is a bet with a known cost and an unknown payoff, and the breakeven is the point where prepaying tax now beats paying it later. On near-zero stock that breakeven sits so low you cross it almost immediately, which is why the math feels lopsided in the founder’s favor.

You are comparing two tax bills. The cost of filing is ordinary income tax, today, on the grant value. You know this number exactly, and on near-zero stock it is close to zero. The cost of not filing is ordinary income tax on each vesting slice, at whatever the stock is worth on each vesting date. You do not know that number, because you do not know the future price, but you know the structure: the higher the stock climbs while you vest, the bigger this bill gets.

Put as a fork between two rates: without the 83(b), the growth between grant and each vest gets taxed at your ordinary rate, which tops out at 37% for 2026 2026 on income over $640,600 single or $768,700 married filing jointly. With it, that same growth gets taxed at the lower long-term capital gains rate when you eventually sell, which for 2026 is 0%, 15%, or 20% depending on income 2026 (the 20% rate starts above $545,500 single or $613,700 married filing jointly), with the 3.8% net investment income tax on top for high earners 2026. The election wins whenever the stock rises above your grant value and the gap between the ordinary rate and the capital gains rate is worth more than the small tax you prepaid. The breakeven gets meaningful only when the grant value is already high, because then the tax you prepay is real cash and you need enough appreciation, with enough certainty, to justify it.

Show the math: the cheap grant vs the expensive one

Cheap grant. 50,000 shares at $0.01, a $500 grant value. Filing prepays tax on $500, roughly $185 at a high rate. If the stock ever reaches even $1, your position is $50,000 and the election has already converted a $49,500 gain from ordinary rates to capital rates. You cleared the breakeven the moment the stock budged off a penny. This is why the answer is “file” without much thought.

Expensive grant. Same 50,000 shares, but you joined later and the stock is already $4, a $200,000 grant value. Filing now means paying ordinary tax on $200,000 in cash this year, perhaps $74,000 at a high rate, on shares you cannot sell. For that bet to pay off, the stock has to rise enough that the capital-gains saving on the future growth beats the $74,000 you fronted, and the company has to not fail in the meantime. If it triples, the election looks smart. If it stalls or folds, you paid $74,000 for nothing. Same form, completely different decision, and the only thing that changed is the grant value.

How to actually decide

The tax you prepay turns on your own 2026 marginal bracket, not just the top rate, so size it against the rate that fits your income.

What this means for you

If your stock is worth almost nothing, file the 83(b) and move on. It is one signed letter standing between you and a future tax bill that can dwarf what the shares cost you. If the stock already carries real value, treat the election as the genuine bet it is, size the cost, and be honest about the odds before you prepay. Then go file it the right way, because the one move you cannot undo is letting the 30-day clock run out. When the stake could ever be large either way, get a fast read inside the window.
