Before You Incorporate: Entity Choice and QSBS Paperwork

You are about to file formation documents, and the entity box looks small. It is the first place where a founder stock tax exclusion can be lost. Treat entity choice before incorporation as a tax decision, not a paperwork detail.

Entity choice is the first tax decision

Qualified small business stock, or QSBS, is the stock that can get the Section 1202 exclusion, a federal tax benefit, and a shareholder can receive that treatment only if the issuing company is a domestic C corporation. That makes the C corporation versus LLC question the first gate.

An LLC can be a good operating vehicle for a small services plan. A C corporation is the path that keeps founder shares eligible for the exclusion. The checklist below turns that choice into records.

Check these six things before you file

Use this list before you sign formation papers. Each item is a minute-level check, not a legal opinion. The first two items protect eligibility. The next three protect the record. The last item catches the plans that should not chase the benefit.

• Confirm the entity will be a domestic C corporation, not an LLC.
• Write down whether the business can use at least 80% of its assets in an active qualified trade or business.
• Record the original issuance date, share count, price, and who receives the stock.
• Prepare a gross-asset schedule at each issuance, because the OBBBA tax law raised the aggregate gross-asset limit from $50 million to $75 million for qualifying QSBS issued after July 4, 2025.
• File and preserve proof of the 83(b) stock tax election for any restricted stock issued to founders.
• Flag any plan that is mostly services or that would start as an LLC, because the second gate is the deciding question.

The entity gate is the first stop. Formation documents that create an LLC send you back to the choice. The business gate forces you to say, in plain words, whether the company is actually running a qualified business rather than holding cash or buying services.

The original-issuance record is the quiet part. Put the date, share count, price, and recipient names in a one-page memo. Keep it with the formation documents. When a later investor asks why the founder shares were issued the way they were, the memo answers before the lawyer starts digging.

The gross-asset schedule is the proof that the company stayed under the limit at each round. At each issuance, make a simple schedule: assets in, assets out, total assets before the new stock. You do not need a full balance sheet. You need a number you can defend.

Restricted founder stock needs the 83(b) election proof to start the clock. A missing election can turn a clean founder grant into a later tax argument. Keep the filed form, the date, and the recipient's signature in the same folder.

Paperwork makes the benefit real

The OBBBA created a phased exclusion structure for newly issued QSBS. Before the OBBBA changes, Section 1202 generally required a shareholder to hold QSBS for more than five years before any exclusion became available. The expanded Section 1202 benefits apply only to QSBS issued after July 4, 2025. For that newer stock, the OBBBA set the fixed exclusion amount at $15 million and left the 10-times-basis limit unchanged.

Those numbers matter at the exit, but the file is built before the first dollar of revenue. The original-issuance memo, the gross-asset schedules, and the 83(b) election proof are the things a tax professional will ask for first. One folder makes the benefit easier to defend. Scattered email threads make it harder to keep.

Do not chase the benefit for a mostly services plan

A mostly services business should not force the entity choice just to keep the option open. Paperwork will not save a plan that holds cash, buys out a service business, or waits for a product that does not exist yet. Choose the entity that fits the real business, and keep the records where the next professional can find them.
