The Internal Revenue Service lists the 15th day of the 4th month after the end of your tax year in Publication 509 (2026), Tax Calendars | Internal Revenue Service.

These include the specific software entry required to trigger the extension, the PIN requirement for e-filing, the error check for red messages, the address update procedure, the foreign entity rule, and the e-file limit for specific forms. Each of these points is tied to a specific publisher’s guidance.

Deadline rules for partnerships, corporations, and associations
Verify the specific entity type before setting the extension deadline, as the IRS Instructions for Form 7004 (12/2025) define distinct timelines for different business structures. For most entities, the filing deadline for Form 7004 is tied directly to the original return due date. To request an extension, file Form 7004 by the applicable return due date IRS.
C corporations with specific year-ends have a different rule. The IRS states that C corporations with tax years ending June 30 and beginning before January 1, 2026, are eligible for an automatic 7-month extension of time to file IRS. If such a corporation is filing Form 1120-POL, the automatic extension is 6 months instead of 7 IRS. This distinction is critical for tax professionals preparing returns for these specific entities, as the extension length varies based on the form type used.
An entity using an automatic extension that does not require Form 7004 must still meet its filing and payment obligations IRS. However, the obligation to file the return and pay any balance due remains. The IRS specifies that these entities must file, or request an additional extension of time to file, and pay any balance due by the 15th day of the 6th month following the close of the tax year IRS. Check the applicable filing and payment deadlines before relying on an automatic extension.

Software settings for Drake and Intuit extension entries
When entering extension data in Drake Tax, follow the specific workflow for the 1120-S. Choose Yes for federal, enter the banking information and select the 7004 option, as reported by Drake Software. If the client makes a payment, enter an Amount paid with extension to have an amount carry to the return and the result letter, according to Drake Software. For entities requiring dual filing, such as partnerships with foreign partners, Drake Tax specifies a distinct process. Important: this should only be done if you need to file both an extension for 1065 (code 09) and an extension for 8804 (code 31), published by Drake Software. In this specific dual-filing scenario, on the EF Selections screen select the 1065 to e-file instead of the 7004, as stated by Drake Software.
For users working in Lacerte, the entry fields require specific numeric codes to process the extension correctly. For Form 2350 separately, enter 1 in the field labeled 1 = Form 2350, 2 = blank (MANDATORY), according to Intuit. When printing the extension documents, in the Print extension: 1=1065 2=8804 3=both field enter a 1, reported by Intuit. These settings ensure the software generates the correct form types for the specific entity structure.
Verify the original due date of the client's return to determine the Form 7004 filing deadline.
PIN requirements and e-filing limitations for specific forms
When preparing an extension in Drake Tax - 1120-S: Extension Form 7004, verify whether a payment accompanies the filing. According to Drake Software, you generally do not need to complete the PIN screen if there is no payment with the extension. This rule applies specifically to the federal extension process described in that documentation. If the client’s situation involves a state extension, the requirements may differ. Drake Software notes that if e-filing a state extension, the PIN screen may need to be completed to allow state extension e-filing (where supported), even if the PIN screen is not required for the federal extension. Therefore, check the state-specific settings before finalizing the e-file. Do not assume the federal PIN exemption carries over to state filings without verification.
For practitioners using Lacerte, specific form types have e-filing restrictions. The 7004 extension that is generated for the 8804 can't be e-filed, according to Intuit. If your practice handles Form 8804 returns, plan to print and mail the associated extension form rather than attempting an electronic submission. This limitation is specific to the 8804 form type within the Lacerte environment. Other form types may have different e-filing capabilities, so verify the specific form ID before initiating the e-file process.
Action step: Confirm whether the extension includes a payment, whether it is federal or state, and whether it concerns Form 1120-S or Form 8804 before checking PIN requirements and e-filing restrictions.
Error checks and address updates before submission
Before submitting the Form 7004 extension, run the specific verification steps for your software and confirm the entity’s current address details. These checks prevent common rejection errors and ensure the IRS updates its records correctly.
Software error review
In Drake Tax, check the View/Print mode for any red message pages regarding the return, as reported by Drake Software. This step identifies formatting or data entry issues that may block the e-file. Review every red message page listed in the View/Print output before proceeding to transmission. If the software flags an error, resolve the specific item cited in the red message before attempting to file again.
Address change notification
If the entity’s mailing address has changed since you filed your last return, use Form 8822, Change of Address; or Form 8822-B, Change of Address or Responsible Party—Business, to notify the IRS of the change, according to IRS. This requirement applies when the mailing address has changed since the last return was filed. Filing the appropriate form ensures the IRS directs future correspondence to the correct location.
Foreign entity verification
Check the box on line 2 if you are requesting an extension of time to file for a foreign corporation that does not have an office or place of business in the United States, published by IRS. This specific line item applies only to foreign corporations without an office or place of business in the United States. Do not check this box for domestic entities or foreign corporations that maintain a U.S. office. Verify the entity’s status against this definition before marking line 2 to avoid misclassification errors.
