2025 TurboTax Business won't file a CA partnership return without a CA SOS file number

roblyman — Sat, 14 Feb 2026 21:31:35 GMT

I am trying to file my CA partnership return (CA 565) with 2025 TurboTax Business (Windows Desktop version), and the program is preventing me from E-filing because of a lack of a CA SOS file number. I was able to successfully E-File my federal partnership return (Form 1065).

When I go through the File State Return Now workflow, I reach a Transmit Returns Now page. After pressing the button to file, I am taken to a step titled "We Need to Make One More Check", then "Reviewing Your Return", then "Check this Entry" requesting that I enter my CA SOS File No. My partnership is a small 3-partner general partnership and CA does not require a SOS File No to E-file (I checked this). However, TurboTax Businsess still prevents me from E-Filing (for lack of a number). I tried entering '0000000' and '9999999' as a work around, but TurboTax Business accepts neither of these as well, and continues to prevent me from E-Filing with California (forcing met through the workflow again, repeatedly).

Does TurboTax confirm this problem, and is there any plan to fix it?

Thanks!

I would like to take a deeper look at this. However, I need a diagnostic file which is a copy of your tax return that has all of your personal information removed. You can send one to us by following the directions below:

TurboTax Online:

Sign into your online account.
Locate the Tax Tools on the left-hand side of the screen.
A drop-down will appear. Select Tools
On the pop-up screen, click on “Share my file with agent.”
This will generate a message that a diagnostic file gets sanitized and transmitted to us.
Please provide the Token number in a reply to this post.

TurboTax Desktop/Download Versions:

Open your return.
Click the Online tab in the black bar across the top of TurboTax and select “Send Tax File to Agent”*
This will generate a message that a diagnostic copy will be created. Click on OK and the tax file will be sanitized and transmitted to us.
Please provide the Token Number that was generated in the response.

*(If using a MAC, go to the menu at the top of the screen, select Help, then Send Tax File to Agent”)

I've investigated your experience and the screen that you see that says Check this Entry "Secretary of State file number must be entered" is informing the user that the number is missing. You should still be able to e-file your return.

Make sure that you entered "other reason" on this screen:

If you can't e-file, please reply back.
