How to Transfer Shares in a US Corporation — Without Getting It Wrong

Transferring shares in a US corporation sounds straightforward — one shareholder sells, another buys, done. In reality, it is one of the most process-heavy events in corporate governance, and one of the most commonly mishandled.

A share transfer done incorrectly can invalidate the transaction, trigger unexpected tax consequences, breach shareholder agreements, and create cap table disputes that take years and significant legal fees to unwind. For foreign founders managing US corporations from the UK, Canada, India, or Singapore, these risks are compounded by distance and unfamiliarity with US corporate law.

Here is the full process — explained clearly, so your share transfer goes through correctly the first time.

Why Share Transfers in US Corporations Are More Complex Than They Look

Unlike transferring cash or property, transferring shares in a US corporation involves multiple overlapping legal, contractual, and tax considerations:

• Your Shareholders' Agreement or Bylaws may restrict who shares can be sold to and require existing shareholders to be offered the shares first

• Federal and state securities laws may apply even to private company share transfers

• The IRS has specific rules around how share transfers are valued, reported, and taxed — particularly for foreign shareholders

• Your corporate records must be updated across multiple documents for the transfer to be legally effective

None of these steps happen automatically. They require deliberate action — and a qualified company secretary or corporate compliance provider to coordinate them correctly.

Step 1 — Review Your Shareholders' Agreement and Bylaws First

Before any share transfer begins, the first step is always to review your governing documents. Most US corporations have restrictions on share transfers written into their Shareholders' Agreement, Bylaws, or Stockholders' Agreement that must be followed before a transfer can proceed.

The most common restrictions include:

Right of First Refusal (ROFR) — existing shareholders must be offered the shares at the same price and on the same terms before they can be sold to an outside party. If any shareholder wishes to exercise their ROFR, the proposed external buyer cannot proceed.

Right of First Offer (ROFO) — the selling shareholder must offer the shares to existing shareholders before going to market, but the price is not pre-set by an external offer.

Co-Sale Rights (Tag-Along) — if a majority shareholder sells, minority shareholders may have the right to sell their shares on the same terms.

Lock-In Periods — shares issued to founders or early employees may be subject to a vesting schedule or lock-in period during which they cannot be transferred at all.

Board or Shareholder Approval — some agreements require the board or a majority of existing shareholders to approve any new shareholder before the transfer is completed.

Skipping this review step and proceeding directly to transfer is one of the most common — and most costly — mistakes in share transactions. Your company secretary should run this check before any other step is taken.

Step 2 — Agree on Valuation

Once the transfer is confirmed as permissible under your governing documents, the next step is agreeing on the value of the shares being transferred.

For private companies, shares are not publicly traded — so there is no market price. Common valuation approaches include:

• Agreed fair market value between buyer and seller

• Book value based on the company's financial statements

• Third-party valuation — required in some cases, particularly for transfers to related parties or where the IRS might scrutinise the price

Valuation matters for tax purposes. The IRS looks at whether shares were transferred at fair market value. If shares are transferred at below-market value — particularly between related parties — the difference may be treated as a gift or compensation, creating unexpected tax obligations.

For foreign shareholders transferring shares in a US corporation, additional rules may apply under the Foreign Investment in Real Property Tax Act (FIRPTA) or withholding tax provisions. Always confirm the tax treatment with your accountant before proceeding.

Step 3 — Prepare the Share Transfer Agreement

Once valuation is agreed and all transfer restrictions have been satisfied, prepare a formal Share Transfer Agreement (also called a Stock Transfer Agreement or Stock Purchase Agreement depending on the transaction).

This document should clearly set out:

• The full legal names of the transferor (seller) and transferee (buyer)

• The number and class of shares being transferred

• The agreed purchase price per share and total consideration

• Representations and warranties from both parties

• Conditions precedent — anything that must happen before the transfer completes

• The effective date of the transfer

• Governing law — typically the state of incorporation

Both parties must sign the agreement. For foreign-based shareholders, ensure signatures are properly executed and, where required, notarised or apostilled for use in US legal proceedings.

Step 4 — Execute the Stock Certificate or Book-Entry Transfer

US corporations issue ownership evidence in one of two ways:

Physical stock certificates — if your corporation issues paper certificates, the transferor must endorse the back of the existing certificate (or complete a separate stock power document) and hand it to the corporation for cancellation. A new certificate is then issued to the transferee.

Book-entry (uncertificated) shares — increasingly common in modern corporations, particularly Delaware C-Corps. Ownership is recorded electronically in the corporate share register without physical certificates. The transfer is effected by updating the register.

Your company secretary should manage this process and ensure the cancelled certificate (or book-entry change) is properly recorded and retained.

Step 5 — Update the Cap Table and Corporate Share Register

This is the step most frequently overlooked — and the one that causes the most problems down the line.

Every share transfer must be reflected in:

The corporate share register — the official record of who owns how many shares of each class. This is a mandatory corporate record in all US states.

The cap table — your company's ownership breakdown showing each shareholder's name, share class, number of shares, percentage ownership, and any options or warrants outstanding.

The corporate minute book — the transfer should be documented alongside the board or shareholder resolutions approving it, the signed transfer agreement, and any updated shareholder register.

An outdated cap table is one of the most common deal-breakers during investor due diligence. If your records do not accurately reflect current ownership — because a previous transfer was never properly recorded — you will face expensive and time-consuming remediation before any new funding round or acquisition can close.

This is exactly why maintaining clean, current corporate records is a core function of corporate compliance — not a formality.

Step 6 — File Any Required State or Federal Notices

Depending on your state of incorporation and the size of the transaction, share transfers may trigger reporting obligations:

State securities laws (Blue Sky laws) — most private share transfers between sophisticated parties are exempt from state securities registration, but an exemption notice may still need to be filed with the state securities regulator.

IRS reporting — if the transfer involves a foreign seller, the buyer may be required to withhold a percentage of the purchase price and remit it to the IRS under applicable withholding rules. Seek specialist tax advice before completing any transfer involving a non-US resident.

Annual filing update — your next annual filing with the Secretary of State may need to reflect any changes to ownership structure, particularly if the transfer results in a change of majority ownership or beneficial control.

How Share Transfers Connect to Your Tax Obligations

Share transfers have direct implications for your business tax return and ongoing small business tax filing obligations:

• Capital gains tax — the transferor may owe federal and state capital gains tax on any gain between their original cost basis and the sale price

• S-Corp eligibility — if your corporation has elected S-Corp status via Form 2553, a share transfer to an ineligible shareholder (such as a non-resident alien or another corporation) will automatically terminate the S-Corp election — a significant and often irreversible tax consequence

• Stamp duty equivalent — while the US does not have a federal stamp duty, some states impose a transfer tax on share transactions

Before completing any transfer, your accountant should confirm the tax treatment for both the seller and buyer, and your company secretary should confirm whether the transfer affects any existing tax elections.
