One exit, more than one exclusion


Section 1202 lets a qualifying shareholder exclude gain on the sale of qualified small business stock, up to a cap per taxpayer, per company. Because the cap belongs to each taxpayer, shares given to separate taxpayers, such as properly structured non-grantor trusts, can each carry their own cap. This tool shows how that can change the arithmetic of a sale.

Sale proceeds minus basis, for all the stock at issue.
Often nominal for founders. Matters only if 10 times basis exceeds the dollar cap.
When was the stock issued?
Separate non-grantor trusts receiving gifted shares

Each is assumed to be a separate taxpayer with its own cap. Gifts to adult children work similarly.
75%
Split evenly across the trusts.
Enter a percentage, such as 5.75. Several states, including California, do not follow Section 1202.
Federal rate assumptions
The cap defaults to $15 million for stock issued on or after July 5, 2025 and $10 million for earlier stock. It is indexed for inflation after 2026.

Assumptions

What the numbers leave out


The illustration is deliberately simple. It assumes:

  • The company and the stock meet every Section 1202 requirement, including C corporation status, the gross asset test at issuance, the active business test, and original issuance.
  • A married founder files jointly. On a joint return, spouses share one cap, so a spouse does not add a separate cap.
  • Each trust is respected as a separate non-grantor taxpayer and is not combined with the others under the multiple trust rules of Section 643(f).
  • Shares move to each trust by gift, which carries over the holding period and qualified status. A sale to a trust would not.
  • At the 3 and 4 year tiers, the cap limits eligible gain before the exclusion percentage is applied, and the rest of the eligible gain is taxed at the §1202 rate.
  • No prior exclusions from the same company, and gain spread evenly across all shares.
Implementation

The arithmetic is the easy part


A stacking strategy only works if several things line up at once, often years before a sale. The stock has to qualify from the day it is issued. The trusts have to be drafted and administered as genuinely separate taxpayers with real purposes beyond tax. The gifts have to be documented, valued, reported, and reflected in the company's own records, consistent with its transfer restrictions and shareholder agreements.

That work usually sits with three different advisors, and it holds together best when they plan together.

Corporate counsel

Keeps the company's qualification intact and makes sure transfers are permitted and properly recorded.

Estate planning counsel

Designs the trusts so they are respected as separate taxpayers and fit the rest of the family's plan.

CPA

Tracks basis and holding periods and reports the gifts and the eventual sale correctly.

Most problems we see are not bad strategy but small implementation gaps: a trust that was signed but never funded, a transfer papered as a sale, a trust unintentionally taxed as a grantor trust, or a plan built from general-purpose forms that were never designed with Section 1202 in mind. Any one of these can undo the benefit the plan was meant to deliver.
