You have a tight 45‑day clock, or an even tighter January 5 cutoff, for Form 8806 plus downstream 1099‑CAP. That is where delivery either makes you look like a hero, or it steals nights and weekends from your team.
At Accountably, we step in so you keep control, keep quality, and keep your advisory time intact. Most firms do not stall because of sales, they stall because delivery becomes the ceiling. Our job is to give you disciplined, secure capacity that fits your standards, so Form 8806 reporting feels routine, not risky.
Form 8806 must be filed within 45 days after the transaction, or, if earlier, by January 5 of the following year. Brokers can rely on limited published data if you make the consent election.
Key Takeaways
- You must file Form 8806 when a domestic reporting corporation has an acquisition of control or a substantial change in capital structure, and shareholders receive cash or property with an aggregate fair market value of at least $100 million.
- The deadline is the earlier of 45 days after the event or January 5 of the next year, so late‑December deals compress the timeline.
- For many transactions you must also furnish and file Form 1099‑CAP, with a $1,000 de minimis per recipient and an e‑file threshold of 10 aggregated information returns beginning in 2024.
- If you elect publication consent on Form 8806, the IRS publishes limited deal data that helps brokers meet §1.6045‑3 reporting, which can ease clearing‑organization furnishing.
- As of April 29, 2025, the IRS instructs that Form 8806 filings must be sent by fax to 844‑249‑6232 until further notice. Do not mail.
- Control uses §304(c)(1) by reference and applies §318 attribution rules, with §958(b) for certain foreign ownership, so test indirect and related‑party holdings.
What Form 8806 Covers
Form 8806 is the information return that alerts the IRS to major corporate events that change who controls the corporation or reshape its capital structure. In practice, it turns on two questions. First, did an acquisition of control occur under the control test that looks through constructive ownership. Second, did shareholders receive cash or other property with an aggregate fair market value of $100 million or more. Answer yes to either trigger, and you move into a 45‑day, earlier‑of timing regime.
The form itself asks for the reporting corporation’s legal name, address, EIN, any common parent details, each acquirer’s identifiers, a clear description of the transaction, key dates, and the fair market value and type of consideration provided to shareholders, class by class. If you choose the publication consent election, the IRS will publicly post only the limited items brokers need. That publication does not include shareholder identities.

- Workflow discipline, SOP‑driven execution with standardized workpapers, naming, and version control.
- Review protection, layered QC that cuts partner time.
- Security and continuity, SOC 2 aligned controls, role‑based access, zero local storage, and continuity plans that prevent disruption.

How to Test Filing Necessity
Acquisition of control
Control for Form 8806 tracks the first sentence of §304(c)(1) and applies §318 attribution rules, with §958(b) where relevant. This means options, entities, and related parties can pull you over the control line even if no single certificate shows it. You file if a second corporation that did not previously control your corporation obtains control, and the acquired stock has a fair market value of at least $100 million.
Practical example. Parent P forms Newco, acquires 100 percent of Target T in a cash‑and‑stock deal. If the stock acquired has FMV of $100 million or more, and T’s shareholders receive cash, stock, or other property, the 8806 control test is met. Layer in attribution, then confirm whether section 367(a) gain recognition applies for any outbound element.
Substantial change in capital structure
A substantial change exists when your corporation changes its capital structure, shareholders receive $100 million or more in cash or other property, and there is section 367(a) gain recognition by the corporation or any shareholder because of the transaction. Mergers, consolidations, transfers of all or substantially all assets, and changes in identity, form, or place of organization can qualify. Measure what shareholders actually receive on the transaction date, across all affected classes.
Practical example. A domestic C‑corp merges into another domestic C‑corp, and all shareholders receive a mix of cash and stock worth $175 million in total. If section 367(a) gain applies to any shareholder or the corporation, you have a substantial change, and Form 8806 is required under the earlier‑of deadline.
Recipient rules and de minimis
You still have investor‑level obligations through Form 1099‑CAP for each shareholder who is not an exempt recipient, but there is a practical screen. You do not furnish 1099‑CAP to any shareholder whose total cash plus FMV of stock and other property does not exceed $1,000. Exempt recipients include corporations, tax‑exempt organizations, IRAs, governments, financial institutions, and certain regulated entities. Keep exemption certificates on file.
Common pitfalls we prevent
- Counting only the cash, and missing property or deemed amounts from liability assumptions that push you past $100 million.
- Misjudging control because attribution rules were not applied across entities and families.
- Waiting on final shareholder rolls, then bumping into the January 5 cutoff.
- Treating clearing organizations like exempt recipients when the publication consent election was not made.
Our teams pressure test facts early, reconcile deal documents to cap tables, and stage workpapers so you can make clean, quick calls and keep the timeline intact.
Deadline Rules, Filing Sequence, and Broker Coordination
Core timing
- File Form 8806 by the earlier of 45 days after the triggering event or January 5 of the following calendar year.
- File Forms 1096/1099‑CAP with the IRS by February 28, or March 31 if electronic. Furnish 1099‑CAP statements to shareholders by January 31.
- If a clearing organization is the record holder, furnish 1099‑CAP to the clearing organization by January 5 unless you made the publication consent election on Form 8806.

Completing Form 8806 Accurately
Reporting corporation details
Start with the exact legal name, address, and EIN as they appear in IRS records. Add any common parent information. Enter the date or dates that gave rise to the acquisition of control or capital‑structure change. If you intend to reduce clearing‑organization friction, consider the publication consent election, which allows limited IRS publication that brokers can use for §1.6045‑3 reporting.
Checklist you can follow:
- Match entity name and EIN to IRS records to prevent rejects.
- List each transaction date that contributes to the reportable event.
- Keep narrative labels short and precise, then tie them to deal documents.
- Stage support for per‑class cash, stock, and other property at fair market value.
Acquiring corporation information
For each acquirer, provide legal name, address, EIN, whether it was newly formed, and any common parent data. Where multiple acquirers exist, list each and align the date fields to your closing mechanics. If stock is part of consideration, note class and quantity. If section 367(a) gain applies, state that clearly to support the substantial‑change analysis.
Transaction description and values
Use concise descriptions that mirror the agreements. For example, “Merger of T into A, 100 percent of T acquired,” then provide the closing date and the aggregate cash and FMV of stock or other property by class. For mixes of cash and stock, prepare a per‑class bridge that ties to your shareholder lists and transfer agent statements. This is the workpaper that accelerates review and reduces back‑and‑forth later.
Publication consent election
If you check the consent box on Form 8806, the IRS may publish your corporation’s name and address, the date of the transaction, a brief description of affected shares, and per‑share amounts of cash and FMV of stock or other property. That limited notice is designed to help brokers satisfy §1.6045‑3. It does not publish shareholder identities or TINs.
Filing Mechanics You Must Get Right
As of April 29, 2025, the IRS notes that Form 8806 filings must be submitted by fax until further notice. The IRS’s update points you to fax submission rather than mail, and the historical notice lists the fax number as 844‑249‑6232. We advise documenting your fax confirmation and retaining a complete copy set with deal support.
For 1099‑CAP, remember the modern e‑file rule. The electronic filing threshold for information returns is now 10, calculated by aggregating all information returns you file, effective for returns due on or after January 1, 2024. If you are at or above that threshold, e‑file 1099‑CAP.
A truncation reminder. You may truncate a recipient’s TIN on payee statements, but you may not truncate the filer’s TIN, and you may not truncate any TIN on forms filed with the IRS. Be extra careful when furnishing to a clearing organization.
Reviewer‑ready workpapers
To keep partner time focused on strategy, we build a reviewer‑ready pack:
- A control memo that applies §318 attribution and, where relevant, §958(b).
- Threshold worksheet that proves the $100 million test with ties to source data.
- 1099‑CAP recipient list with de minimis and exemption screens, plus contact data.
- Evidence of the consent election decision and the reasoning for or against it.
- A calendar with the earlier‑of deadline, shareholder furnish date, IRS filing date, and any clearing‑organization date.

FAQs for CPAs, EAs, and Accounting Firms
When exactly is Form 8806 required?
File when there is an acquisition of control or a substantial change in capital structure, and shareholders receive cash or other property totaling $100 million or more in FMV. Substantial change also requires section 367(a) gain recognition by the corporation or any shareholder.
What is the filing deadline?
You must file by the earlier of 45 days after the event or January 5 of the next year. Build your calendar from the actual closing date, then test whether January 5 lands sooner.
Do I still need to send 1099‑CAP to all investors?
You must file 1099‑CAP for each non‑exempt shareholder who received consideration, but you do not furnish to any shareholder whose total is $1,000 or less. Exempt categories include corporations, certain funds, and governments. Keep evidence of exemption or certificates.
How does the consent election on Form 8806 help?
If you elect publication consent, the IRS publishes limited deal details that brokers can use to meet §1.6045‑3 obligations. This can reduce your need to furnish to clearing organizations. The publication omits shareholder identities.
Can I mail Form 8806?
No. As of April 29, 2025, the IRS instructs that Form 8806 must be filed by fax until further notice, and the historical notice lists 844‑249‑6232 as the fax number. Retain fax proof.
What are the 1099‑CAP deadlines?
Furnish 1099‑CAP statements to shareholders by January 31. File 1096 and 1099‑CAP with the IRS by February 28, or March 31 if you e‑file, and remember the 10‑return aggregated e‑file threshold. For clearing organizations, furnish by January 5 unless you made the consent election.
Which control test applies?
Use the control test tied to §304(c)(1) and apply §318 attribution rules, with §958(b) where relevant for certain foreign ownership. Consider options, related parties, and indirect holdings.
Can I truncate TINs on 1099‑CAP?
You may truncate a recipient’s TIN on payee statements, but do not truncate the filer’s TIN, and do not truncate any TIN on copies filed with the IRS.
What if I miss the 8806 and 1099‑CAP deadlines?
Penalties apply under section 6652(l), with a per‑day cap and an overall cap tied to the acquisition or capital change. The rules also treat Form 8806 and all 1099‑CAP for that event as one return for penalty purposes. Act quickly to correct and document reasonable cause if applicable.
