Cap Table Administration for Startups

Your cap table organizes ownership and potential ownership. It must reconcile with the stock ledger, governing documents, approvals, and transaction records. A spreadsheet or specialist platform can maintain those records; accuracy depends on the underlying information and controls.

Every equity grant, option award, conversion, and transfer has legal consequences — for your founders, your investors, and your ability to qualify for valuable tax treatment under Section 1202. Errors made early are expensive to fix later, and some cannot be fixed at all.

At Carney Badley Spellman, Joe Wallin provides ongoing cap table counsel to early-stage startups in Washington State and across the country. This is not software support. It is legal guidance from an attorney with more than 25 years of experience in startup equity, tax law, and venture finance.

We Work With All Major Cap Table Platforms

You do not need to change your software to work with us. We provide legal counsel alongside whatever platform your company uses — Carta, AngelList Equity, Eqvista, or any other cap table management tool. We know how these platforms work, and we know what they cannot do.

Software tracks your equity. It does not advise you on it.


What Cap Table Administration Actually Requires

Cap table administration requires accurate records and timely attention to legal and tax questions, including:

  • 83(b) election requirements. For substantially nonvested property transferred for services, evaluate an election within 30 days after the transfer. If the last day falls on a Saturday, Sunday, or applicable legal holiday, Section 7503 moves it to the next qualifying day. Preserve evidence of timely filing. Missing an election can change the timing and amount of compensation income; the tax cost depends on the facts.
  • QSBS eligibility under Section 1202. Review original issuance, gross assets, redemption rules, and the C-corporation and active-business requirements during substantially all of the holding period. The eligible-gain limit and exclusion percentage are separate calculations. Qualifying stock acquired after July 4, 2025 can receive a 50%, 75%, or 100% exclusion after three, four, or five years, subject to the applicable per-issuer dollar limit or ten-times-basis alternative. Acquisition-date, prior-gain, contributed-property, and other rules matter. An accurate cap table helps document eligibility but cannot establish it by itself. See Section 1202 and the QSBS guide.
  • Vesting schedules and acceleration provisions. Poorly drafted or incorrectly administered vesting creates disputes at acquisition and departure.
  • Option pricing and securities-law compliance. Analyze the applicable Section 409A stock-right exemption, including grant-date fair market value. An independent appraisal is one valuation safe harbor, not a universal requirement. Separately, identify a securities exemption and satisfy its conditions; Rule 701 may apply to qualifying compensatory issuances. A valuation report does not establish securities-law compliance.
  • Equity issuance documentation. Preserve valid corporate authorization, effective award terms, required acceptance, and transaction records. Delaware law permits specified delegation of issuance and option-grant authority; not every award requires a separate board vote. Apply the governing law, plan, and actual delegation. DGCL Sections 152 and 157.

What Can Go Wrong

The most expensive cap table mistakes share a common trait: they were invisible until the moment they mattered most.

  • Without a timely, valid 83(b) election, appreciation in substantially nonvested service stock can become ordinary compensation income as the Section 83 restrictions lapse, after accounting for the amount paid.
  • A redemption can disqualify affected stock under Section 1202’s timing, ownership, and threshold rules. It does not automatically disqualify every share the company has issued.
  • An option that fails the applicable Section 409A exemption requires further analysis; a noncompliant deferred-compensation arrangement can expose the service provider to additional tax and create reporting or withholding obligations. The absence of an outside appraisal alone does not establish a violation.
  • A cap table with undocumented transfers or missing board approvals delays — or kills — an acquisition.

These examples illustrate issues that require review of the actual documents and facts. Software records alone do not establish that the legal and tax requirements have been satisfied.
