QSBS Attorney in California

Published September 3, 2026  ·  6 min read

I'm Abboud Chaballout, a California-admitted attorney and the founder of Vide Law. My practice is focused on QSBS planning under Section 1202 for California founders and early employees, covering eligibility analysis, trust stacking, gift tax coordination, and the California non-conformity problem that makes state-tax jurisdiction the highest-leverage part of the work.

This page tells you what I do, when to hire me, and how to book a complimentary consultation. If you're a California founder holding QSBS or expecting to, that first call is the fastest way to know whether planning makes sense for your situation.

What I'm looking for in a founder's situation

Before I take on a QSBS engagement, I'm trying to answer five questions.

Is the stock likely to be worth more than the exclusion cap? First and foremost, I want confidence that the founder's stock will end up worth more than the per-taxpayer exclusion cap (currently $10 million for pre-OBBBA stock, or $15 million for stock issued after July 4, 2025). This is a gut-feel question, not a strict or scientific test. If the anticipated gain is well below the cap, a single founder can capture the full exclusion without stacking, trust design, or jurisdiction gymnastics, and the planning is much simpler. I ask this question first because it saves everyone time and money to know upfront whether the plan justifies the engagement.

Is the company actually QSBS-qualified? Not “we set up as a C corp” but actually qualified under the full test. Gross assets under $75 million for post-OBBBA stock or $50 million for pre-OBBBA stock, 80% of assets in active qualified trade or business, no disqualifying redemptions, no excluded industries. My first job is to confirm that assumption with primary evidence: cap table, financial history, board consents, redemption ledger. (You can start with our QSBS Eligibility Checklist to see where your company stands before we talk.)

Where in the startup journey are we? The shape of the analysis depends heavily on stage. Pre-formation is ideal for the foundational decisions: entity choice, cap table structure, and building QSBS eligibility into the company from day one. These are simplest and cheapest to get right before the company exists, so I love working with founders at this stage. Post-formation, the analysis depends on how far along the company is and what the shares are worth today. We typically use the company's most recent 409A valuation as initial guidance to gauge current share value, but for actual gifting we'll need a proper gift tax appraisal in most cases (the 409A is a starting point, not a defensible position for the IRS). Knowing what the shares are worth today lets us model how many trusts might be justified and how many shares to put in each while staying within the founder's remaining lifetime gift tax exemption. For deep trust stacking with a specific exit in mind, 18 to 36 months before likely exit is the sweet spot. Even closer to exit, there are usually still moves worth considering.

Where do the beneficiaries live? California's throwback rules mean an out-of-state trust with a California-resident beneficiary can lose its state tax benefit when distributions flow. If the founder's spouse and children live in California, that constrains the strategy differently than if the family is distributed across states.

Who else is on the team? QSBS engagements coordinate with the founder's CPA, financial advisor, gift tax appraiser, and independent trustee. Good outcomes come from good coordination, not from replacing advisors the founder already trusts.

How I approach the work

Most of what an attorney does in a QSBS engagement is document work: trust instruments, gift tax returns, board resolutions, valuation memoranda. But the value of the engagement is upstream of the documents. It's in the decisions that determine what the documents need to say: how many trusts, what type, who the beneficiaries are, where they're sited, when each is funded, and what language distinguishes them under Section 643(f).

Gift tax analysis in particular is central to the work and something I bring into the picture early. Every share transfer to a stacking trust is a taxable gift, which means it consumes some portion of the founder's lifetime gift tax exemption (currently $15M per person). Gifting too much too late, when share values have appreciated, can burn through the entire exemption on QSBS transfers alone and leave nothing for other estate planning. Gifting too little means missing exclusion buckets that could have been captured. The gift tax math constrains how many trusts are worth setting up, how many shares go into each, and when. Getting this right requires modeling the gift tax picture alongside the Section 1202 analysis, not treating it as a separate afterthought.

I take a holistic view of a founder's planning. A QSBS engagement rarely sits in isolation. It intersects with the entity structure, the cap table, the founder's broader estate plan, compensation planning for early employees, coordination with the financial advisor on liquidity timing, and the eventual reporting position the CPA will take at exit. A well-run engagement closes all six gaps at once: eligibility analysis, stacking strategy, trust formation, jurisdiction selection, gift tax coordination, and professional coordination across the advisor team. Miss one and you've usually left significant value on the table or introduced a risk that surfaces at exit.

Those decisions are the engagement. The documents just record them. When I take on a QSBS matter, most of the early hours are conversation, with the founder, with the CPA, with the financial advisor, and sometimes with the spouse or a co-founder, mapping the planning question before touching a trust template.

Why the California non-conformity matters

The final piece of context: why this practice is California-focused in the first place.

Section 1202 is a federal exclusion. A California founder who properly qualifies for the full $10 or $15 million per-taxpayer exclusion pays zero federal capital gains tax on that amount at exit. On paper it looks the same as it does for a founder in Austin or Miami.

Except California doesn't conform. The state imposes its regular capital gains tax, up to 13.3%, on the entire gain, including the amount fully excluded federally. You can model different exit sizes and stacking scenarios in the calculator. As a reference: on a $20 million exit, that's $2.66 million in California tax on gain the federal government has agreed you owe nothing on. On a $50 million exit with stacking, it's $6.65 million. The federal savings are real. The California tax bill on top of them is also real, and it scales linearly with the size of the win.

That's the reason I focus this practice where I do. In a state that conforms, QSBS is mostly a corporate and tax analysis. In California, it's that plus a trust and jurisdiction problem, and the trust and jurisdiction problem is where most of the money is either saved or lost. Getting the federal analysis right is table stakes. Getting the California overlay right is what separates a good outcome from a great one.
