You have 30 days to make an 83(b) election, and no one at the IRS has discretion to extend it. If the window closed, there is no late-filing fix. But the analysis does not end there. Before accepting the tax consequences of a missed election, two questions are worth asking. Did the election window ever actually open? And can the award be restructured now to reach a similar result going forward? This guide walks through both.
What an 83(b) Election Does
When you receive stock or other property for services and that property is subject to vesting, I.R.C. section 83, Property Transferred in Connection with Performance of Services controls when you pay tax. The default rule under section 83(a) taxes you as the property vests, on the excess of its fair market value on each vesting date over anything you paid for it. If the value climbs between grant and vesting, so does your ordinary income.
An election under section 83(b) flips the timing. You elect to include the property's value in gross income at transfer, when the value is often low, rather than at vesting. If you later sell the stock as a capital asset, post-transfer appreciation is then generally taxed as capital gain rather than as compensation. The election also starts your capital gains holding period at transfer. For founders and early employees, the difference can be enormous.
The 30-Day Deadline Is Nearly Absolute
The election must be filed no later than 30 days after the date the property is transferred. Treas. Reg. section 1.83-2, Election to Include in Gross Income in Year of Transfer is explicit on this point.
Two narrow mechanical rules soften the edge, and neither involves IRS discretion. If the thirtieth day falls on a Saturday, Sunday, or legal holiday, I.R.C. section 7503 treats a filing on the next business day as timely. And when the IRS postpones deadlines for a federally declared disaster or for combat zone service, the 83(b) election is among the time-sensitive acts that can be postponed under I.R.C. section 7508A. Rev. Proc. 2018-58, 2018-50 I.R.B. 990, lists it expressly. Outside those situations, the deadline is what it is.
Some tax elections can be rescued after a missed deadline through the relief procedures in Treas. Reg. sections 301.9100-1 and 301.9100-3, commonly called 9100 relief. The 83(b) election is not one of them. The 30-day deadline appears in the statute itself, and 9100 relief does not extend statutory deadlines. The IRS has never provided a discretionary mechanism for late 83(b) elections. If the window closed, it closed.
Revocation Is Just as Narrow
The rigidity runs in both directions. A timely 83(b) election generally cannot be undone either. Under Rev. Proc. 2006-31, 2006-2 C.B. 32, the IRS will consent to revocation only where the person who made the election was under a mistake of fact as to the underlying transaction, and only if the revocation request is filed within 60 days of discovering the mistake. A mistake about the property's value or about the tax consequences of the election does not qualify.
The Better Question: Did the Window Ever Open?
An 83(b) election is relevant only when two things are true. Property must actually be transferred in connection with the performance of services, and the property must be substantially nonvested, meaning subject to a substantial risk of forfeiture and nontransferable. Treas. Reg. section 1.83-3, Meaning and Use of Certain Terms defines both concepts. If no transfer occurred, there was nothing to elect on. If the property was already vested when transferred, section 83(a) generally taxed it at transfer and no election was needed. Either way, the 30-day window never opened, and there was nothing to miss.
No Transfer Ever Occurred
A transfer occurs when the service provider acquires beneficial ownership of the property. The inquiry is substantive, not formal. If the purported issuance never actually conferred beneficial ownership, for example because the company had no shares available to issue, then the 83(b) period may never have begun. The reverse is also true. A missing certificate or defective paperwork does not by itself defeat a transfer that occurred in substance. In P.L.R. 200820010 (May 16, 2008), the company lacked available shares to issue under a restricted stock agreement. The IRS ruled that the 83(b) election was void ab initio because no transfer had occurred to open the election window at all.
The Property Was Already Vested
The election also has no role if the property was not subject to a substantial risk of forfeiture when transferred. In P.L.R. 200832019 (Aug. 8, 2008), the IRS ruled that an 83(b) election was ineffective because the stock was not subject to a substantial risk of forfeiture at transfer. The stock was simply taxable under section 83(a) at the time of transfer. Note what that means in practice. Taxation at transfer, at transfer-date value, is exactly the result an 83(b) election would have produced. If your shares were fully vested when you received them, the missed election likely cost you nothing.
What to Review
Whether the window ever opened is a factual question. The documents that answer it include the board consent authorizing the issuance, the stock purchase or restricted stock agreement, the company's capitalization records showing the shares were actually issued, and the vesting and repurchase terms in effect on the transfer date. If the record shows no completed transfer, or shows fully vested shares, the analysis changes entirely.
Restructuring After a Missed Window
If the window did open and did close, the election itself cannot be salvaged. But the parties are not powerless. Practitioners sometimes use the label "synthetic 83(b)" for a family of restructuring strategies that aim to replicate the election's economics prospectively. The common approaches include accelerating vesting so the shares become taxable now at current value, amending the award to make the shares transferable, and adjusting the company's repurchase right from cost to fair market value. The last of these has direct support in the regulations, which provide that property is not subject to a substantial risk of forfeiture to the extent the employer must pay fair market value on its return. The transferability route needs more care. Transferability is itself a defined concept under Treas. Reg. section 1.83-3(d), and shares are transferable only if the transferee's rights are free of the forfeiture condition, so a nominal right to transfer may accomplish nothing.
Some parties also consider canceling the existing award and making a genuinely new grant at current fair market value. If the regrant is respected as a new transfer for tax purposes, it carries its own 30-day election period. Whether it will be respected as a new transfer, rather than treated as a continuation of the old arrangement, is a fact-intensive question that deserves careful analysis before anyone relies on it.
These strategies deserve real caution. None of them is blessed by IRS guidance as a fix for a missed election. Each fixes ordinary income at today's value, which may already be substantial. The changes can weaken the retention incentives that vesting exists to create, and investors may object for that reason. Any restructuring also needs a defensible current fair market value, often informed by the company's most recent valuation under I.R.C. section 409A, along with attention to the award documents and applicable corporate law requirements. This is planning to undertake with counsel, not a form to file.
One note on terminology. "Synthetic 83(b)" is not a term of art, and in the partnership context it often means something different. A qualifying profits interest granted for services replicates the 83(b) result automatically. Under Rev. Proc. 93-27, 1993-2 C.B. 343, as clarified by Rev. Proc. 2001-43, 2001-2 C.B. 191, the grant is not taxable and no election is required, though many advisors file a protective election anyway. If your equity sits in an LLC taxed as a partnership, that framework governs, not the corporate rules above.
The Bottom Line
There is no discretionary late relief for a missed 83(b) election, and no 9100 rescue. Revocation of a timely election is available only for a narrow mistake of fact, on a 60-day clock. The productive work after a missed deadline is factual and structural. First determine whether a completed transfer of substantially nonvested property ever occurred. If it did not, the election window never opened and the missed deadline is a non-event. If it did, restructuring may still fix the go-forward tax result, at a price that needs careful measurement.
Frequently Asked Questions
How long do I have to make an 83(b) election?
Thirty days from the date the property is transferred. The deadline comes from the statute itself, and the IRS has no discretion to extend it.
Can the IRS grant relief for a late 83(b) election?
Not as a discretionary matter. The 9100 relief procedures that rescue some late regulatory elections are not available for the 83(b) election. The only softening rules are mechanical. I.R.C. section 7503 treats a filing as timely when the deadline falls on a weekend or legal holiday, and deadlines postponed for federally declared disasters or combat zone service under I.R.C. section 7508A can include the 83(b) election.
Can I revoke an 83(b) election I already filed?
Only with the consent of the IRS, and consent is granted only for a mistake of fact as to the underlying transaction. The request must be made within 60 days of discovering the mistake. Mistakes about value or tax consequences do not qualify.
What if my company never actually issued the shares?
Then no transfer occurred, section 83 was never implicated, and the election window never opened. The IRS reached this conclusion in P.L.R. 200820010, ruling the attempted election void ab initio. There was nothing to elect and nothing to miss.
What if my shares were fully vested when I received them?
Then no election was needed. Property that is not subject to a substantial risk of forfeiture is taxed under section 83(a) at transfer, which is the same timing an 83(b) election would have produced. The IRS confirmed this analysis in P.L.R. 200832019.
Is there a way to fix the tax result going forward?
Sometimes. Restructuring strategies such as vesting acceleration, transferability amendments, repurchase price adjustments, or a cancel-and-regrant can fix ordinary income at current value and convert future appreciation to capital gain. Each carries tax, valuation, and corporate governance risks and requires professional guidance.
How do I make a valid 83(b) election next time?
File within 30 days of the transfer. The IRS now provides Form 15620, Section 83(b) Election for this purpose, and keep proof of timely filing. Identify and calendar the transfer date immediately. The 30-day period runs from the transfer of the property, not necessarily from the date the documents were signed.
