To elect Qualified Subchapter S Subsidiary (QSub) status for an eligible subsidiary, the parent S corporation files IRS Form 8869 with the service center where the subsidiary last filed its return, entering the parent’s information in Part I, the subsidiary’s information in Part II, and an effective date that falls no more than 2 months and 15 days before the filing date and no more than 12 months after it. These Form 8869 instructions walk through the eligibility check, each part of the form, the effective-date rules, where to mail it, and what to do next.
Confirm the Election Is Valid Before You File
Three conditions have to be true on the effective date and throughout the period that follows:
- The parent has a valid S corporation election already in place. If the parent’s S election is defective or has terminated, the QSub election falls with it.
- The parent owns 100 percent of the subsidiary’s stock.
- The subsidiary is a domestic corporation and is not an “ineligible corporation” under the Internal Revenue Code. Ineligible corporations include financial institutions using the reserve method of accounting for bad debts, insurance companies taxed under Subchapter L, and any corporation that is or was a Domestic International Sales Corporation (DISC).1Office of the Law Revision Counsel. 26 USC 1361 – S Corporation Defined
The subsidiary has to meet these requirements for the entire period beginning on the effective date, not just on the filing day.2eCFR. 26 CFR 1.1361-3 – QSub Election
One additional caution before filing. If the subsidiary owes the parent more than the fair market value of the subsidiary’s assets, the deemed liquidation triggered by the election may not qualify for tax-free treatment under Sections 332 and 337, and the subsidiary will recognize gain or loss on the assets deemed distributed.3eCFR. 26 CFR 1.1361-4 – Effect of QSub Election Talk to a tax professional first if intercompany debt exceeds asset value.
Filling Out Form 8869
The form has two parts.4Internal Revenue Service. Form 8869 – Qualified Subchapter S Subsidiary Election
Part I — Parent S Corporation. Enter the parent’s legal name, address, Employer Identification Number (EIN), tax year ending date, and the service center where it last filed its income tax return.
Part II — Subsidiary. Enter the subsidiary’s name, address, EIN if one has been assigned, and the date and state of incorporation. Line 11 is where the effective date goes; that decision has its own rules and is covered in the next section.
Signature. An officer authorized to sign the parent S corporation’s tax return signs the form under penalties of perjury. The signer is personally vouching for the accuracy of everything on it.
More than one subsidiary at a time. File one Form 8869 for the first subsidiary and attach a separate statement for each additional one. Each attachment repeats all Part II information for that subsidiary along with the parent’s name and EIN.5Internal Revenue Service. Instructions for Form 8869
Picking the Effective Date on Line 11
The effective date cannot be more than 2 months and 15 days before the filing date, and it cannot be more than 12 months after the filing date.6eCFR. 26 CFR 1.1361-3 – QSub Election – Section: Effective Date of Election A form filed on March 1 can bear an effective date anywhere between December 15 of the prior year and March 1 of the following year.
If line 11 is left blank, the election takes effect on the filing date. For a brand-new subsidiary that the parent wants treated as a QSub from day one, use the subsidiary’s formation date.5Internal Revenue Service. Instructions for Form 8869
An effective date outside the permissible window will not be accepted as requested. The IRS may treat the election as effective on the nearest permissible date, or the parent may have to seek late election relief.
Where to Mail the Form
This is where filers most often go wrong. Form 8869 is mailed to the IRS service center where the subsidiary filed its most recent tax return, not the parent’s service center. The one exception: when the parent forms a brand-new subsidiary and makes the QSub election effective on formation, the form goes to the service center where the parent filed its most recent return.5Internal Revenue Service. Instructions for Form 8869
The specific mailing address depends on the state where the relevant corporation is located and is found in the instructions for Form 1120-S (for the parent) or the subsidiary’s most recent return type (often Form 1120 for a C corporation being converted). The IRS does not offer electronic filing for Form 8869, so it must go by mail.
File the Subsidiary’s Final Return
If the subsidiary was a separate taxpaying corporation before the QSub election, such as a C corporation, it generally must file a final income tax return for the short period ending the day before the QSub effective date.5Internal Revenue Service. Instructions for Form 8869 Mark it as a final return. It is filed separately and is not attached to Form 8869.
No final return is required if the QSub election is made as part of a reorganization under Section 368(a)(1)(F) and Revenue Ruling 2008-18, which typically applies when a business restructures its S corporation through a new entity while keeping the same ownership and operations.
The parent does not file Form 966 (Corporate Dissolution or Liquidation) for the deemed liquidation. The liquidation is deemed rather than actual.5Internal Revenue Service. Instructions for Form 8869
What the Election Does Once It Takes Effect
On the effective date, the subsidiary is treated as having liquidated into the parent S corporation. No assets actually move and no stock is physically surrendered; the IRS simply treats the subsidiary as if it distributed everything to the parent and ceased to exist as a separate income taxpayer. From that point forward, the subsidiary’s income, deductions, credits, assets, and liabilities are reported on the parent’s Form 1120-S.3eCFR. 26 CFR 1.1361-4 – Effect of QSub Election
The QSub election itself satisfies the requirement that the parent adopt a formal plan of liquidation for Section 332 purposes. In a typical situation where the parent owns all the stock and the subsidiary is solvent, the deemed liquidation is tax-free.
Payroll Taxes Stay With the Subsidiary
A QSub is disregarded for federal income tax purposes but remains a separate entity for federal employment taxes. The subsidiary keeps its own payroll obligations: withholding and depositing employment taxes, filing employment tax returns, and issuing W-2s to its employees. The parent handles its own payroll separately.3eCFR. 26 CFR 1.1361-4 – Effect of QSub Election
As a practical matter, the subsidiary keeps its existing EIN for those employment-tax purposes. Mixing up which entity files employment returns is a common way to draw IRS notices.
If You Missed the Deadline
When the parent intended to make a QSub election but filed too late for the requested effective date, Revenue Procedure 2013-30 provides automatic late election relief if the request is made within 3 years and 75 days of the intended effective date.7Internal Revenue Service. Late Election Relief
To qualify for automatic relief, the parent must show that it intended to make the QSub election, that the failure to file on time was not intentional, and that the parent and its shareholders reported their income consistently with the election having been in effect. If those conditions are met and the 3-year-and-75-day deadline has not passed, the IRS generally grants relief without a private letter ruling.7Internal Revenue Service. Late Election Relief
If the corporation does not qualify for automatic relief or has passed the time limit, the remaining option is a private letter ruling, which requires a user fee and a case for why the Commissioner should grant an exception.
Check State Rules Separately
Not every state follows the federal QSub election automatically. Some states require their own QSub or S corporation election. Before assuming the subsidiary is disregarded at the state level, verify what each state where the subsidiary operates requires.
