What Reporting Is Required When a Company Is Acquired

An acquisition can eliminate a company. It does not necessarily eliminate that company's unfinished reporting obligations.

If employees exercised incentive stock options (ISOs) or transferred shares acquired through an Employee Stock Purchase Plan (ESPP) before the acquisition closed, those transactions may still need to be reported.

The question is: Who is responsible for filing?

The Reporting Obligation Can Survive the Deal

A company's dissolution does not automatically eliminate its information-reporting duties for transactions that occurred before the acquisition.

Depending on the deal structure, responsibility may remain with the original company or shift to the successor through the IRS combined reporting procedure.

It does not shift automatically.

When Can the Successor Take Over?

The successor and predecessor may use combined reporting when the transaction meets the IRS requirements.

1. Confirm the Acquisition Qualifies

Generally:

• The successor must acquire substantially all the property used in the predecessor's business, or a separate part of that business.
• The predecessor must have reportable transactions before the acquisition.
• The predecessor must have no reportable transactions after the acquisition.

2. Choose Which Forms to Combine

The companies may use combined reporting for all eligible information returns or only selected forms, including Forms 3921 and 3922.

For each form included, the successor assumes the predecessor's full reporting responsibility.

3. Notify the IRS

The successor must file a separate statement identifying the forms covered by combined reporting.

The statement must include information about both companies, including their:

• Names
• Addresses
• Phone numbers
• Employer identification numbers (EINs)

4. Report the Covered Transactions

For Forms 3921 and 3922, the successor reports:

• The predecessor's applicable pre-acquisition transactions
• The successor's own applicable transactions for the year

If the companies do not use combined reporting, or the acquisition does not qualify, each company remains responsible for reporting its own transactions.

Don't Automatically Move Old Transactions to the New EIN

Even when the successor handles the filing, the historical transaction data must remain connected to the company, plan, and transaction from which it originated.

Preserve:

• The original company's EIN
• The applicable ISO or ESPP plan information
• Grant, exercise, and purchase dates
• The identity of the company that issued or transferred the stock

Forms 3921 and 3922 are tied to the corporation and transaction that created the reporting obligation. An acquisition alone does not justify relabeling historical records under the acquiring company's EIN.

Four Questions That Determine Who Files

1. Which company issued or transferred the stock?

This identifies the originating company, EIN, and plan connected to the transaction.

2. When did the transaction occur?

Pre-acquisition exercises and ESPP transfers may create reporting obligations for the period before the deal closed.

3. Does the original company still exist?

A surviving subsidiary may continue to have its own reporting responsibilities.

4. Did the successor formally assume responsibility?

Confirm that the acquisition qualifies and that the companies followed the IRS combined reporting procedure. Without that, responsibility does not automatically transfer.

Make Section 6039 Part of the Deal Checklist

Do not wait until filing season to determine who owns the reporting.

During due diligence and integration, confirm:

• Which company is responsible for each filing
• Whether combined reporting is available and has been properly established
• Whether historical ISO and ESPP data remains connected to the correct originating entity
• Whether any transactions were reassigned to the successor's EIN simply for convenience

Addressing these questions early can help prevent missed filings, inaccurate records, and employee confusion.
