The AI checks your answers before you download

12 checks built for this form, so a wrong date or a missing answer is caught before anyone else sees it.

Exclusive Status Selection

This check ensures that only one of the primary status options is selected. A bidder can either be a 'California company' under one of the three specified conditions or 'not a California company', but not multiple statuses simultaneously. This is critical for correctly applying preference rules. If more than one option is selected, the form is considered ambiguous and will be rejected for clarification.

Mandatory Status Declaration

Verifies that the bidder has selected at least one of the four primary status checkboxes (three for 'California company', one for 'not a California company'). The entire purpose of the form is to declare this status. A submission without this declaration is incomplete and invalid, which may lead to the rejection of the entire bid.

Signature and Date Completion

Ensures that both the 'Signature of Bidder' and 'Date' fields are filled. The form is a certification under penalty of perjury, making the signature and date legally essential. Failure to sign and date the form invalidates the certification and is grounds for bid rejection as stated in the form instructions.

Date Format and Plausibility

Validates that the 'Date' field is in the specified 'mm/dd/yyyy' format and represents a real, valid date. The check also ensures the date is not in the future or unreasonably far in the past. An invalid date format can cause processing errors, and an implausible date questions the validity of the signature, potentially leading to rejection.

Conditional Fields for CA Company Option 2

If the bidder checks the box for being a California company with a principal place of business in a state with no local preference, this validation ensures the 'Name of State', 'Reference Website', and 'Statute/Code Citation' fields are all completed. This information is required to verify the claim. Missing information will render the claim unsubstantiated and may cause the preference to be denied.

Conditional Fields for CA Company Option 3

If the bidder checks the box for being a California company that has paid sufficient sales/use taxes, this validation confirms that the 'Name of State' and 'California Sales or Use Tax No.' fields are filled. These details are essential for the contracting agency to verify the bidder's eligibility for this specific preference category. An incomplete submission will prevent verification and lead to the denial of the preference.

Common Mistakes in Completing DOT DES-OE-0102.9

The ones the AI is built to catch.

Forgetting to Sign or Date the Form
This common oversight happens when bidders rush to complete the submission packet. An unsigned or undated form is legally invalid and will be rejected, as the certification is made under penalty of perjury. Bidders must carefully review the form before submission to ensure the signature and date fields are properly completed to avoid automatic disqualification.
Checking Multiple, Conflicting Certification Boxes
Bidders sometimes get confused and check multiple mutually exclusive boxes, such as certifying as both a 'California company' and a 'non-California company'. This creates an ambiguous and invalid submission, which may lead to the bid being deemed non-responsive. You must carefully read the definitions and select only one certification that accurately reflects your company's status.
Failing to Provide Required Details for a Selected Option
This occurs when a bidder checks a box but leaves the associated text fields blank, such as checking Option 2 but not entering the name of the state. This renders the certification incomplete and may cause the bid to be rejected. Always double-check that all required information for your selected option, like state names or tax numbers, is filled in completely.
Misinterpreting 'Principal Place of Business'
Companies with a California branch office might mistakenly claim it as their 'principal place of business' under Option 1. This term has a specific legal definition referring to the 'nerve center' of the business, which may differ from just having a physical presence. Incorrectly certifying this can lead to penalties for perjury and bid disqualification, so it is crucial to understand the legal definition before selecting an option.
Leaving All Certification Boxes Unchecked
Some bidders sign and date the form but neglect to check any of the boxes to certify their company's status. This is a critical omission as it fails to provide the core information the form is designed to collect. This will result in the waiver of preference eligibility for California companies or potential bid rejection for non-California companies.
Incorrectly Claiming 'No Local Preference' in Home State (Option 2)
A bidder might assume their home state has no local contractor preference and check Option 2 without proper verification. This is a serious error, as the certification is made under penalty of perjury and requires supporting documentation like a statute or website. Falsely claiming this can have severe legal consequences and will lead to the bid being rejected.
Misstating Sales/Use Tax Compliance (Option 3)
A company might check Option 3 without meeting the strict requirement of paying at least $5,000 in California sales/use taxes for *each* of the last 5 consecutive years. This mistake can happen if records are not thoroughly checked, and it constitutes a false certification under penalty of perjury. Bidders must verify their complete 5-year tax payment history with the state before selecting this option.
Providing an Incomplete Bid Preference Description
Non-California companies often provide a vague or inaccurate description of their home state's bid preferences, sometimes simply writing 'None' without research. Caltrans uses this information to apply reciprocal preferences, so an incomplete or incorrect answer can lead to bid rejection or miscalculation of the preference. Bidders must thoroughly research and accurately describe all applicable preferences as required.
Entering an Invalid California Sales or Use Tax Number
When completing Option 3, bidders may enter an incorrect, expired, or improperly formatted California Sales or Use Tax Number. This data entry error prevents verification of the tax payment history, invalidating the claim for this preference category. Using a tool like Instafill.ai can help by validating data formats and auto-filling correct information from a company's profile, reducing typos.
Using an Incorrect Date Format
The form explicitly requests the date in mm/dd/yyyy format, but applicants often use other conventions like dd-mm-yy or a non-numeric month. This can cause data entry and processing delays on the agency's end, and in some automated systems, it could be flagged as an error. AI form-filling tools like Instafill.ai can automatically format dates correctly, ensuring compliance and preventing processing issues.
Failing to Complete the Form Entirely
This is a fundamental error where a bidder fails to submit the form at all, believing it doesn't apply to them. The instructions clearly state it must be completed by *all* bidders, and failure to do so has significant consequences, including bid rejection or waiver of preference. If the form is a non-fillable PDF, a tool like Instafill.ai can convert it into an interactive, fillable version to make completion easier.

What is the purpose of the California Company Preference form (DES-OE-0102.9)?
This form is used by the California Department of Transportation (Caltrans) to determine if a bidding company qualifies for a reciprocal preference as a 'California company' on construction contracts. It helps Caltrans apply preference rules fairly during the bid evaluation process.
Who is required to complete and submit this form?
All companies, both from California and from out-of-state, that are submitting a bid on a Caltrans project must complete and sign this form as part of their bid package.
What happens if I don't fill out this form?
If you are a non-California company, your bid may be rejected for being non-responsive. If you are a California company, you will waive your eligibility for any reciprocal preference you might have been entitled to.
How do I know if my business qualifies as a 'California company'?
Your business is a 'California company' if it meets the definition in Public Contract Code § 6107. You must select one of the three 'California company' options on the form that accurately describes your situation, such as having your principal place of business in California.
I am not a California company. What information do I need to provide?
You must check the box indicating you are not a California company, enter the state or country where your principal place of business is located, and describe any bid preferences your company receives in your home state or country.
My company's main office is not in California, but we do a lot of business there. Can we still be a 'California company'?
Yes, potentially. If your principal place of business is in a state with a local contractor preference, you may still qualify if your company has paid at least $5,000 in California sales or use taxes for construction-related activity for each of the last five years.
What information should I have ready before filling out this form?
Depending on your company's status, you may need your principal business address, the name of your principal state of business, and your California Sales or Use Tax Number if applicable. Non-California companies will need to describe any bid preferences they receive from their home state.
How do I submit the California Company Preference form?
This form should be completed, signed, and included with your overall bid package as required by the contract's bidding instructions.
Is an electronic signature valid on this form?
Yes, the form explicitly states that by providing an electronic signature, you agree it is the legal equivalent of your handwritten signature and that you consent to conduct business electronically.
What does 'principal place of business' mean?
Principal place of business generally refers to the primary location where a company's high-level officers direct, control, and coordinate the business's activities. This is often referred to as the company's 'nerve center'.
