You angel-invested $50,000 in a friend's startup in 2019. The company spent five years trying to find product-market fit, raised a small seed round, burned through it, and officially shut down last year. The shares you own are worth zero. You'd love to claim the $50,000 as a capital loss — but there's no 1099-B because there was no broker involved. How do you actually report a worthless security on your return?
Failed angel investments, defunct startups, and worthless private company stock are surprisingly common, and the IRS has a specific rule for reporting them. The mechanics are just unfamiliar because there's no broker-generated paperwork guiding you. Here's the complete process.
The Worthless Securities Rule — IRC §165(g)
Section 165(g) of the Internal Revenue Code allows a capital loss deduction when a security becomes completely worthless during the tax year. The rule applies to:
- Stocks (public or private)
- Bonds and debt instruments
- Options and warrants
- Rights and other securities
The key word is completely. A stock that dropped 95% in value isn't worthless under this rule — you'd have to sell to claim the loss. The 165(g) treatment only applies when the security has zero value and zero reasonable prospect of recovery.
What "Worthless" Actually Means
The IRS uses a high bar for "worthless." It means:
- The company has ceased operations or been officially dissolved
- The stock has no market value and no prospect of future recovery
- Any recovery by shareholders (through liquidation, bankruptcy, or other proceedings) is zero or economically negligible
A stock that's been delisted but is still trading OTC for pennies isn't worthless. A company in Chapter 11 reorganization that might emerge isn't worthless. A company whose CEO has moved on but hasn't officially dissolved the entity isn't worthless.
What usually qualifies:
- Company filed Chapter 7 bankruptcy and was liquidated
- State dissolved the corporation for failure to file annual reports and the business has ceased
- Company shut down with no assets remaining after creditor claims
- Private company's founder officially announced it's winding down and returning remaining cash (if any) to preferred shareholders, leaving common shares with zero recovery
What does NOT qualify:
- Stock down 99% but still trading
- Company in active bankruptcy proceedings (wait for resolution)
- Shares you believe are worthless but the company is still operating
- Stock you simply can't sell because it's illiquid
When the Loss Is Realized
The worthless security rule requires you to claim the loss in the year the security became worthless — not the year you discovered it or the year you "gave up" on it. The IRS treats the security as having been sold for $0 on the last day of the tax year in which it became worthless.
Practical implication: if a company officially dissolved in July 2024 but you didn't find out until March 2026, you can't claim the loss on your 2025 return. You'd need to file an amended 2024 return to claim it in the correct year.
This creates a three-year lookback problem. If you discover the worthlessness years after it happened, you have up to 7 years to file an amended return specifically for worthless securities (the IRS extended the usual 3-year amendment window for this case under IRC §6511(d)). But you still need to claim the loss in the right year.
Reporting on Form 8949 Without a 1099-B
Since there's no 1099-B, the sale lands in Form 8949 Box C (short-term) or Box F (long-term) — the boxes for "transactions not reported to you on Form 1099-B." Use Box F unless you acquired the shares less than a year before they became worthless, which is unusual for private investments.
The entry:
- (a) Description of property: "XYZ Corporation common stock — worthless"
- (b) Date acquired: the date you originally bought or received the shares
- (c) Date sold or disposed of: December 31 of the year the security became worthless
- (d) Proceeds: $0
- (e) Cost or other basis: your original investment amount
- (f) Code: leave blank (no adjustment needed — the $0 proceeds is the correct number)
- (g) Adjustment: blank
- (h) Gain or loss: −$50,000 (or whatever your basis was)
In TurboTax, navigate to the 1099-B section, choose "Add investment" → "Other" or "I didn't receive a 1099-B", and enter the worthless stock transaction manually with the fields above.
Section 1244 Small Business Stock — Ordinary Loss Treatment
One major advantage for angel investors who lost money on early-stage startups: Section 1244 lets you treat some or all of the loss as an ordinary loss rather than a capital loss, up to $50,000 per year ($100,000 married filing jointly).
Ordinary losses are far more valuable than capital losses because they:
- Offset ordinary income (wages, self-employment, etc.) at your full marginal tax rate
- Don't get capped at $3,000 per year the way net capital losses do
- Can reduce your taxable income dollar-for-dollar this year
To qualify under Section 1244:
- The stock must be common stock in a domestic corporation
- The corporation must have been a "small business corporation" at the time the stock was issued (total capital contributions of $1 million or less)
- The corporation must have derived more than 50% of its gross receipts from active business (not passive investments) during its most recent 5 years
- The stock must have been issued to you directly from the company (not purchased on a secondary market)
- You must be an original holder of the stock (not someone who bought it from the original investor)
Most angel investments in early-stage startups qualify under Section 1244 if they were structured as common stock. Preferred stock (which is common in priced seed and Series A rounds) does not qualify — Section 1244 is common stock only. SAFEs and convertible notes don't qualify either until they convert.
How to claim it: report the loss on Form 4797 (Sales of Business Property) instead of Form 8949, with a note that it's a Section 1244 ordinary loss. TurboTax's business loss interview flow handles this if you select "Section 1244 small business stock" during the walkthrough.
The Section 1244 election can turn a $50,000 capital loss (worth ~$7,500 in tax savings over 17 years at the $3,000 annual cap) into a $50,000 ordinary loss (worth $11,000-$18,500 in tax savings this year depending on your bracket). It's a meaningful difference.
Documentation to Keep
For worthless security claims, the IRS wants evidence. Keep:
- The original investment documentation — signed stock purchase agreement, cancelled check or wire confirmation, board consent granting the shares
- Evidence the company is defunct — Secretary of State dissolution filing, bankruptcy court records, a letter from the founder confirming the company shut down and common shareholders received nothing, news articles about the closure
- Cap table confirmation — a final cap table showing your shares existed and were canceled with no distribution
- Communications from the company — the final "we're shutting down" email, liquidation notice, or dissolution announcement
Assemble all of this into a folder and keep it for at least 7 years after filing. You won't attach it to your return, but you'll need it immediately if the IRS questions the loss.
FAQ
Can I claim the loss if the company is still technically a legal entity but has ceased operations?
Risky. The IRS standard is "no reasonable prospect of recovery." If the legal entity exists but there's no operating business, no assets, and no prospect of a liquidation distribution, you can claim the loss — but document why carefully. Board minutes or a letter from the founder confirming there's no path to recovery helps.
What if the company was acquired for less than I paid?
That's not a worthless security — it's a sale at a loss. Report it as a regular Form 8949 transaction with proceeds equal to what you received from the acquisition.
What about a failed SAFE or convertible note?
SAFEs and convertible notes don't qualify for Section 1244 until they convert to stock. If the company shut down before conversion, you have a debt loss (for notes) or a capital loss on the SAFE contract. Debt losses from worthless notes go on Form 8949 similar to worthless stock but are treated as nonbusiness bad debts (always short-term capital loss, regardless of holding period).
Can I use the loss to offset other capital gains?
Yes (as a capital loss). Worthless stock losses flow through Schedule D like any other capital loss — they offset capital gains first, then up to $3,000 of ordinary income, with the remainder carrying forward to future years indefinitely.
Does the founder need to confirm in writing that the company shut down?
Not required, but it's strong audit evidence. A two-sentence email from the founder saying "ABC Corp ceased operations on X date and has no assets remaining" is sufficient.
What if I'm not sure what year the company became worthless?
If it's ambiguous, most tax professionals recommend claiming the loss in the most recent year you can defend. The IRS is more concerned about double-claiming than about timing disputes, so picking a defensible year is usually fine. If you pick wrong, you have up to 7 years to amend.
Bottom Line
Worthless stock from a failed private company is deductible as a capital loss under IRC §165(g), reported on Form 8949 Box C or Box F with $0 proceeds and your original cost basis. For qualifying early-stage common stock, Section 1244 can upgrade the loss to ordinary treatment worth significantly more in immediate tax savings — worth the extra paperwork if you qualify.
The key is documentation: proof the company is defunct, proof of your original investment, and a defensible year in which the worthlessness occurred. The IRS accepts these claims routinely when the paperwork is in order; they reject them when the taxpayer can't prove the security is genuinely worthless.
