Angel investors and founders often overlook one of the biggest tax breaks for startups. Section 1202 lets you exclude some or all of your gain when you sell qualified small business stock (QSBS). People sometimes call it an angel investor tax credit, but it is actually an exclusion from income. For a successful exit, the amount of gain it can exclude can be large.
Section 1202 basics for angel investors
- You may exclude up to 100% of your gain on QSBS held long enough.
- The exclusion for each company is the greater of a dollar cap or 10 times your basis. The cap is $10 million for stock issued before July 5, 2025, and $15 million for stock issued after July 4, 2025.
- For stock acquired after September 27, 2010, the excluded gain isn’t subject to the alternative minimum tax.
- Founders, employees, angel investors and many fund investors can all qualify.
Is there an angel investor tax credit?
Not at the federal level. The federal tax code doesn’t have a general tax credit for angel investors. The main federal tax break for angel investors in startups is the Section 1202 exclusion described on this page. It works differently from a credit: instead of reducing your tax dollar for dollar, it removes qualifying gain from your taxable income when you sell.
Some states have offered their own angel investor tax credits for investments in qualifying in-state companies, usually with an application, annual caps and approval by a state agency. California does not follow the federal Section 1202 exclusion, so California residents generally pay state tax on the full gain. If you invest through another state’s program, check that state’s tax agency for current rules.
Example for founders
A company sells for $50 million. The founder owns 20%, so she receives $10 million. Her basis is close to zero, so her gain is about $10 million. If her stock qualifies as QSBS, she can exclude the entire gain from federal income tax.
Example for angel investors
Another company sells for $500 million. An angel investor put in $100,000 early and now owns 2.5%. So he receives $12.5 million, and his gain is $12.4 million.
Ten times his $100,000 basis is only $1 million. So the $10 million cap applies instead. As a result, he can exclude $10 million and pays tax on the remaining $2.4 million, assuming the stock was issued before July 5, 2025.
Key Section 1202 requirements
- Holding period. Hold the stock more than five years. For stock issued after July 4, 2025, a partial exclusion starts after three years.
- C corporation. The company must be a domestic C corporation, and you must buy the stock directly from it.
- Size limit. The company’s gross assets can’t exceed $50 million before and right after the investment. For stock issued after July 4, 2025, the limit is $75 million.
- Qualified business. Many fields don’t qualify. For example, these include most professional services, finance, farming, mining, hospitality and real estate.
- Non-corporate owner. Corporations that invest don’t get the exclusion.
For the full rules, read our guide to QSBS and Section 1202 or the text of Section 1202. Also note that California does not follow the federal exclusion.
What this means for angel investors and founders
Section 1202 is a strong reason to consider a C corporation over an LLC for a high-growth startup. If you are a founder, check whether your company’s stock qualifies. If you are an angel investor, ask each startup whether it tracks its QSBS status.
Angel investor tax FAQs
Is there a federal angel investor tax credit?
No. The federal tax code doesn’t have a general tax credit for angel investors. The main federal break for startup investors is the Section 1202 exclusion for qualified small business stock, which removes qualifying gain from taxable income when you sell.
Does California allow the Section 1202 exclusion?
No. California does not conform to the federal qualified small business stock gain exclusion, so California residents generally report the full gain on their state return.
How much gain can Section 1202 exclude?
For each company, the exclusion is generally limited to the greater of a dollar cap or 10 times your basis in the stock. The cap is $10 million for stock issued before July 5, 2025, and $15 million for stock issued after July 4, 2025.
