Section 1244 Small Business Stock Loss 2026: The $50,000 and $100,000 Ordinary Loss Rules

Can a failed startup investment really become an ordinary loss?

Yes, if the stock qualifies under Section 1244 of the Internal Revenue Code, and for many first-time angels and founders it does without anyone noticing. A qualifying loss is deductible as an ordinary loss up to $50,000 a year, or $100,000 on a joint return. Anything beyond that falls back into capital loss treatment.

That difference is bigger than it sounds. A capital loss first offsets capital gains, then only $3,000 a year of other income. Someone who put $80,000 into a friend’s company and lost it all could spend decades dribbling that loss out. Under Section 1244 most of it hits your wages or business income in a single year.

My read is that Section 1244 is the most underused provision in small-business tax. It needs no election and no IRS filing in advance. It either applies when you lose the money or it does not, which is exactly why you should check the facts when you invest, not at the moment the company folds.

This guide covers the loss side only. If your question is about excluding gain from a successful exit, that is a different set of rules, and I compare the two further down.

What are the dollar limits, and what happens to the rest?

Two numbers matter. They have been the same for a long time, and they apply per year, not per investment.

Filing status	Annual ordinary loss cap	Excess over the cap
Single, head of household, married filing separately	$50,000	Capital loss
Married filing jointly	$100,000	Capital loss

Three details trip people up.

First, the joint-return cap is $100,000 even if only one spouse held the shares. Second, the cap is per year, so a large loss can be spread by timing: a sale in one year and worthlessness of another block in a different year each get their own ceiling. Third, the excess is not lost. It becomes a capital loss that offsets capital gains and then up to $3,000 of ordinary income per year, with the remainder carried forward.

Here is the arithmetic for a single filer who invested $120,000 and lost all of it:

Piece	Amount	Treatment
Total loss	$120,000
Section 1244 ordinary loss	$50,000	Offsets wages, business income
Remaining capital loss	$70,000	Offsets gains, then $3,000 a year, carryforward

The ordinary piece can also contribute to a net operating loss in a year when your other income is low, which is a real benefit for someone who left a salary to build the company. Whether and how that works depends on the rest of your return, so run the numbers with a CPA.

Which stock and which companies qualify?

Section 1244 has a handful of tests. Fail any one and you are back to plain capital loss treatment.

Test	What the rule requires
Issuer	A domestic corporation, C or S, at the time of issuance
Capital limit	The corporation’s total received for stock, contributed capital and paid-in surplus was $1,000,000 or less when the stock was issued
Consideration	Stock was issued for money or other property, not for services and not for other stock or securities
Holder	The original individual (or a partnership) that received the shares directly from the company
Gross receipts	For the five tax years before the loss (or the company’s life, if shorter), more than half of gross receipts came from active business rather than royalties, rents, dividends, interest, annuities, or stock and securities gains

A few practical notes on those tests.

The $1,000,000 ceiling is measured when your shares were issued, and property counts at its adjusted basis reduced by liabilities. It is not a valuation cap. If a company raises a seed round under the line and a Series A well above it, the earlier shares can qualify while the later ones may not. Where a single offering would cross the line, the corporation generally has to designate which shares are meant to qualify, so ask for that statement in writing.

The gross receipts test is usually where otherwise clean companies get tripped, mostly holding companies and real estate vehicles. A software startup with customer revenue passes easily. A company that mainly collects rent and interest will not. The test is also relaxed for companies that had operating losses over the period, which describes most failing startups, but do not assume it. Have your CPA confirm it against the company’s returns.

Common or preferred stock both work. Convertible notes and SAFEs do not, because they are not stock. If you lent money or signed a SAFE, any loss runs through the debt or capital rules instead. Whether your dollars sit in debt or equity changes the tax result before anything goes wrong, and it is worth thinking about before you fund a deal with a home equity line. If that is on the table, compare it against current mortgage and refinance rates first.

Who can claim it, and who cannot?

Only the original holder. That is the rule that surprises the most people.

Founders who paid cash or contributed property for their shares qualify. Angels who wrote a check to the company at a funding round qualify. Friends-and-family investors who subscribed directly qualify. A partnership that originally held the shares can pass the treatment to partners who were partners when the stock was issued.

These holders do not qualify: someone who bought shares from a founder or another investor, a person who inherited or was gifted the stock, a corporation, a trust, and an estate. A fund structured as an LLC taxed as a partnership can be a qualifying partnership holder, but the fund’s investors are a case for a professional, not a blog post.

One more founder trap: shares granted for services. If you got your 40 percent for building the product and put in no cash or property, those shares are not Section 1244 stock. If you also paid in $25,000, the portion tied to that payment can qualify. Document which dollars bought which shares.

What counts as a loss, and when do I claim it?

Section 1244 applies to a loss from a sale or exchange, or from the stock becoming worthless. It does not cover paper declines. You need a realized event.

Worthlessness is a facts-and-circumstances call. The company has to be out of business with no realistic prospect of recovery: assets liquidated, nothing left for shareholders, no plan to continue. A bad quarter or a down round is not worthlessness. Stock cannot be partially worthless for this purpose. It is all or nothing, and the loss is treated as occurring on the last day of the tax year in which the stock became worthless.

The timing matters because the IRS allows a longer window to correct a worthless-securities claim, seven years rather than the usual three for amending a return. I would still not rely on that. Claim the loss in the right year if you can show the event. A sale to an unrelated buyer, even at a nominal price, is cleaner evidence than arguing about when a company effectively died, but a sale to a related party for a token amount invites scrutiny. Get advice before you do it.

If you are deciding between taking a loss now and holding for a recovery, that is a portfolio question as much as a tax one. For public stock the interplay with wash-sale rules and harvesting is in my tax-loss harvesting guide, and the same capital loss mechanics apply to whatever part of your startup loss exceeds the cap.

How do I report a Section 1244 loss on my return?

The mechanics are not exotic.

1. Confirm the stock qualifies and compute your basis. If you contributed property rather than cash, basis for this purpose is limited to the lesser of your adjusted basis or fair market value at contribution.
2. Report the ordinary portion on Form 4797, Part II, as an ordinary loss, with a clear description identifying it as Section 1244 stock.
3. Report any amount above $50,000 or $100,000 as a capital loss on Form 8949 and Schedule D.
4. Attach whatever statement the current instructions call for, and keep your own supporting file.

Read the current-year form instructions before filing, because form layouts move and my description of the line may not match the version in front of you. If you have a business-loss or NOL consequence downstream, your preparer will carry it through. Settlements and one-off payments get their own treatment, which is why my piece on how the IRS treats lawsuit settlements is a useful reminder that character of income and loss, ordinary or capital, drives everything.

What records should I keep?

Treat this like an audit you expect to have.

Document	Why it matters
Subscription or stock purchase agreement	Shows you bought from the company, for what, and when
Proof of payment (wire, check, bank statement)	Proves money or property actually went in
Stock certificate or cap table extract	Identifies original issuance and share count
Corporate statement on capitalization	Supports the $1,000,000 test at issuance
Company financials or returns for the testing period	Supports the active-business gross receipts test
Evidence of worthlessness or sale	Dissolution papers, bankruptcy filings, sale contract

Ask the company for a capitalization statement at the time you invest, not five years later when the founder has stopped answering email. Companies that fail rarely keep tidy books for their former shareholders.

What is the most common mistake?

Here is a realistic one. A married couple files jointly. One spouse invested $140,000 in a friend’s software company through a SAFE in 2022. It converted to preferred stock in a later round and the company shut down in 2026. They claimed a $100,000 ordinary loss and a $40,000 capital loss.

Two things were wrong. The money went in on a SAFE, so the shares were issued on conversion, and whether the conversion shares count as issued for the original money is a real question that needs a close read of the documents. Second, the company’s last round pushed total capital past $1,000,000, and no one asked for a designation of which shares were meant to qualify. A CPA reviewing the file would likely have limited the ordinary treatment to the qualifying shares.

Item	What they claimed	Risk
Ordinary loss	$100,000	Part may not qualify
Capital loss	$40,000	Understated if ordinary is cut back
Records	A bank statement only	No capitalization statement

The lesson is not that Section 1244 is fragile. It is that the facts you need are cheap to gather at the start and expensive to reconstruct at the end.

Another frequent error runs in the other direction: people with a perfectly good Section 1244 loss report it as a plain capital loss because the broker’s 1099-style paperwork did not flag it. There is no 1099 for private stock. Only you can claim it.

How does Section 1244 differ from QSBS rules under Sections 1202 and 1045?

They sit on opposite sides of the outcome. Section 1244 is the downside protection. Sections 1202 and 1045 are about the upside.

Feature	Section 1244	Section 1202	Section 1045
What it addresses	Losses	Gain exclusion	Gain rollover
Effect	Ordinary loss up to the annual cap	Excludes some or all gain if conditions are met	Defers gain by reinvesting in other QSBS
Company type	C or S corporation	C corporation only	C corporation only
Size test	$1,000,000 total capital received for stock	A gross assets ceiling, which Congress raised for stock issued after mid-2025	Same QSBS definition
Holding period	None	Multi-year, with a tiered schedule for newer stock	Held more than six months, reinvest within 60 days

The numbers under Section 1202 changed with the 2025 tax legislation, so if gain is your question, check the current limits and the issue date of your shares before relying on anything above. The point for this article is that the regimes are independent. The same founder stock can pass Section 1244 for a loss and Section 1202 for a gain. Which one you eventually use depends on how the company ends, not on a choice you make at purchase.

If you eventually sell winners, the routine capital gains rules apply to everything outside those provisions, and my capital gains tax guide is the place to start.

Should I fund a startup around Section 1244?

No. Treat it as a backstop, not a reason to invest. A $50,000 ordinary deduction at, say, a 24 percent bracket is real money, but it is not a refund of the $50,000 you lost. You still lose most of it. I have seen investors talk themselves into a deal because the tax treatment made the downside feel cushioned. It does not.

What I do recommend is a short checklist before wiring money. Is the issuer a domestic corporation? Are you getting stock directly from it? Is it for cash or property? Does the company’s total capital look like it will stay under $1,000,000 for this round? Can you get a one-page capitalization statement? Five minutes of questions now saves a CPA bill later. And if the real risk to the company is something like a cyber incident, a lawsuit or an AI product liability claim, assume the failure scenario is not hypothetical when you size the check.

Your CPA or tax attorney should confirm all of this against your actual facts. This area has several tests that interact, and the answer for your shares depends on documents I have not seen.
