Updated QSBS Attestation to maximize new exclusions and benefits

With H.R. 1, the “One Big Beautiful Bill Act” (OBBB) now in effect, we’ve updated Carta’s Qualified Small Business Stock (QSBS) Attestation to help you and your shareholders track eligibility and take full advantage of the new benefits.

What’s new?

Support for shorter holding periods: for shares issued on or after July 4, 2025, Carta now tracks eligibility for a partial QSBS exclusion after three years (50%) and four years (75%), with full 100% exclusion available after 5 years.

Support for the new $75M asset cap: Carta automatically checks if newly issued shares qualify under the updated $75M aggregate gross asset limit—so you can confidently verify QSBS eligibility at the time of grant.

Expanded individual gain exclusion: Shareholder letters and eligibility summaries now reflect the increased $15M per-person gain exclusion, unlocking even greater potential tax savings.

Updated dashboard indicators: Carta dashboards and reports now show eligibility based on new QSBS rules and issuance windows. This makes it easier for companies and shareholders to understand their status at a glance.

Why is this valuable?

The new QSBS rules offer significant opportunities for tax savings—but only if companies can accurately track and prove eligibility. Carta’s updates simplify this process. By automating complex eligibility checks and updating shareholder documentation in real time, companies can:

These upgrades ensure every eligible shareholder is in a position to receive the full benefits of the new law, with built-in transparency and peace of mind.

How do I access the updated attestation?

No action needed, these updates have already been applied to all active QSBS Attestations and portfolios holding QSBS-eligible shares. If you have questions or would like a walkthrough, reach out to your Customer Success team or visit our Help Center.

Anything else to know?

Our team is closely monitoring policy changes and will proactively revisit your company’s QSBS analysis to help you unlock new shareholder opportunities and ensure your audit records remain up to date.

Get Started guide for companies signing for QSBS Attestation

We've launched a new guided "Get started" workflow for companies that sign up to get QSBS Attestations from Carta. After signing up for a QSBS review with Carta the feature will guide you to provide the Carta Valuations and Tax team the necessary information to perform the attestation.

After signing up the guide simplifies the process of connecting a your company's accounting provider to Carta, making it easy to provide the necessary financial data for your QSBS attestation. This integration will help Carta's QSBS Delivery reduce the back and forth needed to collect historical financial information about your company.

For companies that either do not use one of our supported accounting providers, the guide offers a way to manually upload financial statements, guided by questions that adapt based on your companies size and stage.

This new guide will make it easier and faster to onboard onto our QSBS product, and ensure a timely review from Carta's team. If you have any questions reach out to your assigned Carta account team or qsbs@carta.com to learn more!
