Qualified Small Business Stock can be one of the most impactful tax planning opportunities available to founders and early employees. When it works as intended, it can exclude up to $10 million or 10 times your basis of capital gains at exit! That’s one of the most lucrative tax breaks available.
There’s even more good news for founders who are married and live in a community property state. In the right circumstances, community property rules can effectively double the QSBS exclusions in community property states available to a household. Read on, we’ll tell you how this works, starting with how marital assets are defined.
Understanding Marital Assets
Marital assets are generally assets acquired during a marriage. While that sounds straightforward, the application is often broader than people assume.
Assets acquired before marriage are typically considered separate property and remain owned by the individual spouse. For example, a home that was purchased and paid off before marriage is usually not treated as a marital asset. However, timing alone does not always settle the issue.
An account opened before marriage does not automatically remain separate forever. Contributions made during the marriage, income earned during the marriage, or changes in how an asset is used can cause part or all of it to be treated as marital property. This distinction matters for investment accounts, retirement plans, and equity compensation.
Marital assets can include homes, investment properties, vehicles, bank accounts, retirement accounts, securities, and private company stock. For the purposes of this discussion, we are assuming there are no prenuptial or postnuptial agreements in place. Those agreements can override default state rules and should always be reviewed separately.
What Makes a Community Property State Different
Community property states apply a specific framework to marital assets. In these states, assets acquired during the marriage are generally considered jointly owned by both spouses, regardless of whose name appears on the title or account.
This concept goes further than ownership labels. Earnings during the marriage are typically treated as half earned by each spouse, even if only one spouse is employed. Debts follow the same logic. The result is a system that assumes equal ownership and equal responsibility.
Community property states include Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, Wisconsin, Alaska, Tennessee, South Dakota, and Puerto Rico.
In contrast, most other states follow common law property rules. In those states, ownership is usually determined by title. Assets belong to the spouse whose name is on the account, and marital property is divided based on equitable principles rather than an automatic 50-50 split.
These differences are well known in divorce planning, but they are just as relevant for tax planning during life.
How Community Property Interacts With QSBS
This is where community property rules intersect with Qualified Small Business Stock in a meaningful way.
Consider a founder who receives 400,000 shares in their company. All shares qualify for QSBS, and the cost basis per share is negligible. At the time the shares are issued, the founder is married and living in California. The company is also formed in California.
Five years later, the company is acquired, and the total proceeds from the sale are $55 million. The shares are still titled solely in the founder’s name.
At first glance, it may appear that all of the gain belongs to the founder alone, resulting in a single $10 million QSBS exclusion. That assumption is common, but in a community property state, there’s more that can be done.
Because the shares were acquired during the marriage, community property rules generally treat half of those shares as belonging to the other spouse. Even though the stock certificates are in one name, ownership is split evenly under state law.
That split matters for QSBS. Each spouse is treated as owning their respective shares, which means each spouse may be eligible for their own QSBS exclusion. In this example, the household can potentially exclude up to $20 million of gain rather than $10 million.
Why This Works Under Current Law
The QSBS exclusion is governed by Section 1202 of the Internal Revenue Code. The statute includes rules for married taxpayers, joint returns, and separate returns, but it does not carve out special treatment for community property states.
Despite opportunities to revise this language, the rules have remained unchanged. As a result, community property ownership is respected when applying the QSBS exclusion, even when shares are titled in only one spouse’s name.
In practice, this position is supported by careful analysis and, in many cases, formal opinions from tax professionals. The key is that ownership is determined under state law first, and federal tax treatment follows from that ownership.
Why Timing and Facts Matter
While the opportunity can be significant, it is highly dependent on facts and timing.
Were you married at the time the shares were issued?
Were you living in a community property state at that time?
Where do you live now, and where was the company formed?
Has anything changed that could affect how ownership is characterized?
Founders often assume that moving states later invalidates this planning. That is not always true. For example, someone who founded a company while married in California and later moved to Texas may still remain within a community property framework, since Texas also follows community property rules.
These nuances are easy to miss, especially when the focus is on building the company rather than planning for a future exit.
At KB Financial Advisors, we keep an eye on these nuances for our clients and we ensure the documentation lines up so that they are well-positioned to get their full QSBS exclusion.
Understand How QSBS Applies To You
QSBS planning is not just about meeting holding periods or confirming eligibility at the company level. In community property states, what appears to be a $10 million exclusion on the surface may actually be $20 million when ownership is properly understood. That difference is worth the time it takes to evaluate correctly.
At KB Financial Advisors, this type of analysis is a core part of our work with founders and tech professionals. We help clients understand how equity, marital status, residency, and timing all interact long before a liquidity event occurs.
If you are approaching an exit or want to understand how QSBS applies to your situation, a short consultation can make a meaningful difference.
Until next time!
