What is 28-03?
Form 28-03, Reduced Business License Tax Application, is the City of Irvine form that a business submits to ask for a reduction in its business license tax when its gross receipts are low, as defined in Irvine Municipal Code section 4-6-202.
The Regulatory Affairs Unit decides whether the business qualifies, so completing the form does not grant the reduction by itself. The two-page form has three yes/no questions (A, B and C), a calculation of the reduced tax and a business certification signed under penalty of perjury.
The form defines gross receipts as all receipts, cash, credits and property of any kind or nature, with no deduction for the cost of property sold, materials, service or labor, interest paid, losses or other expenses.
A business that is administrative, executive, research, or a sales/corporate office or similar function that does not generate income does not qualify for the reduction. For those businesses the form says the annual business license tax is fixed instead of reduced.
Form 28-03 is not the business license application. It is filed with the Renewal or New Business License Application, and it is printed as Form 28-03 Rev 04/14.
Who needs to file 28-03?
Each business entity that is renewing or applying for an Irvine business license and believes it qualifies for the reduced tax submits this form with its renewal form or application.
To qualify, the business must meet all of these conditions on the form:
- It answers NO to question A: it is not an administrative, executive, research or sales/corporate office, or similar function, that does not generate income. Transactions where sales are forwarded to a corporate office do not qualify.
- It answers NO to question B: its gross receipts are not greater than $4,000.
- It answers YES to question C: it can provide a Schedule C, a State Board of Equalization form, or copies of a contract agreement or sales receipts.
If you answer YES to A or B, stop: the business does not qualify. If you answer NO to C, stop and contact Regulatory Affairs before proceeding.
The owner or an authorized representative of the business signs the certification, stating a title. The form does not list other signers.
When to file 28-03
Submit Form 28-03 whenever you renew an Irvine business license or apply for a new one, because the form says each business entity renewing and/or applying must send it with its renewal form or application. No separate due date is printed on the form.
Qualifying for the reduction does not remove other amounts owed. Late fees and prior year adjustments still apply, and you must include them in your payment to the City of Irvine for the application to be processed. For a renewal, the renewal notice you recently received shows accrued late fees. For a new license, use the "Computation of Fees" chart on the business license application. Questions go to Regulatory Affairs at (949) 724-7128.
Documents you need
- Renewal or New Business License Application form: submit it together with Form 28-03, as instruction 3 on the form directs.
- Schedule C, Profit or Loss from business, for the last calendar year: one of the accepted proofs for question C.
- State Board of Equalization form: an alternative proof for question C.
- Copies of a contract agreement or sales receipts: an alternative proof for question C.
- Any other documents requested with the license application: the form says to attach all requested documents, for example Schedule C or contract agreements.
How to fill out 28-03
Enter the business information
Fill in the business name, any additional business names (DBAs), the owner or authorized representative, the business phone, and the business address with suite, city, state and ZIP. The address cannot be a P.O. Box or Mail Drop.
Answer question A
Mark YES or NO to whether the business is administrative, executive, research or a sales/corporate office or similar function that does not generate income. If you answer YES, stop: the business does not qualify.
Answer question B
Mark YES or NO to whether gross receipts are greater than $4,000, counting all receipts without deductions. If you answer YES, stop: the business does not qualify.
Answer question C and gather proof
Mark YES if you can provide a Schedule C for last calendar year, a State Board of Equalization form, or copies of a contract agreement or sales receipts, and attach it. If you answer NO, stop and contact Regulatory Affairs at (949) 724-7128.
Calculate the reduced tax
Only if you answered NO to A and B and YES to C, enter your state gross receipts, round off to the nearest dollar, divide by 100, and add the fee and the disability access fee printed on the line. Enter the total at the end of the line.
Account for late fees or adjustments
Check your renewal notice, or the Computation of Fees chart on the new business license application, for late fees or prior year adjustments. These are not part of the reduction and must be included in your payment.
Complete the business certification
Enter your name as owner or authorized representative and the business name in the certification statement. By signing you certify, under penalty of perjury, that gross receipts are $4,000 or less and that you will provide relevant records on request.
Sign, title and date
Add the applicant signature (required), your title and the date.

Common mistakes to avoid
- Sending Form 28-03 alone instead of with the Renewal or New Business License Application.
- Leaving the applicant signature blank; the form says the signature is required for processing.
- Continuing past question A or B after answering YES; the form says to stop because the business does not qualify.
- Answering NO to question C and proceeding without contacting Regulatory Affairs first.
- Deducting costs of goods, materials, labor, interest or other expenses from gross receipts; the form counts them without any deduction.
- Claiming the reduction for transactions where sales are forwarded to a corporate office, which do not qualify.
- Leaving out late fees or prior year adjustments from the payment to the City of Irvine; they are still owed and are needed to process the application.
- Entering a P.O. Box or Mail Drop as the business address, which the form says is not acceptable.
- Completing only one page; the form says to complete all pages.
