California Business Personal Property Statement: Form 571-L Due April 1, May 7 Penalty Date, $100,000 Rule

If your business owns equipment, fixtures, or other tangible property, you may have an annual filing with your county assessor that most new owners never hear about. It is the business property statement, usually reported on Form 571-L. This is a county property tax matter. It is not a state income tax return and it is not a sales tax return. The Franchise Tax Board and the CDTFA do not collect it.

This guide covers who has to file the California business personal property tax statement, what goes on it, the deadlines, and what happens if you miss them. Counties differ in the details, so confirm every date and procedure with your own county assessor.

What the business property statement is

Under Revenue and Taxation Code 441, every person who owns taxable personal property with an aggregate cost of $100,000 or more for the assessment year must file a signed property statement with the county assessor. The statement reports your taxable business personal property. The assessor uses it to value that property for the California business personal property tax.

The form is a State Board of Equalization form, but the county assessor administers it. Counties may accept it electronically in the way their assessor approves. Do not assume one submission method works everywhere.

Do you need to file Form 571-L in California?

Start with the total aggregate cost of your taxable business personal property for the assessment year. The rule works like this:

• $100,000 or more in aggregate cost: You must file a signed statement with the county assessor.
• Less than $100,000: You are not automatically required to file, but you must file if the assessor asks. The assessor can also assess your property even if you never received a request, so do not ignore a letter from the assessor's office.

Some owners are more likely to reach the threshold than others. Home-based businesses with equipment, salons, restaurants, and trucking or other equipment-heavy operations often fall into this group. That does not mean every salon or restaurant reaches $100,000. Add up what you own, including used equipment and older purchases, before you decide. If you run your business from home, our California home-based business laws, zoning, permits and taxes guide covers related rules.

What counts as taxable business personal property

Taxable business personal property, such as equipment and fixtures, is reported at cost. Two common categories are treated differently:

• Inventory and computer software: The San Bernardino County Assessor treats these as exempt. Other counties may differ, so confirm the treatment and the current form version with your own county assessor.
• Low-value property: Under Revenue and Taxation Code 155.20, a county may exempt low-value personal property up to $10,000 of value where the tax would cost more to collect than it brings in. The exact amount differs by county, so ask your assessor what applies to you.

Because exemptions vary, do not use a single number from another county or from an online article as your exemption amount.

Deadlines at a glance

The statement is filed each year in the window that opens on the lien date and closes at 5 p.m. on April 1. The key dates are:

Date	What it means
January 1	Lien date. The annual filing window opens.
April 1, 5 p.m.	Statement due to the county assessor.
May 7	10% penalty applies to any statement not filed by this date.
May 31	Last day to amend for errors and omissions that were not willful. No penalty applies to the amended statement.

Two timing rules matter in practice. A mailing with a postmark counts as filing on that date. If May 7 falls on a weekend or holiday, a statement postmarked on the next business day counts. April 1 is the due date. May 7 is the date the penalty attaches, so do not plan around it.

The 10% penalty and how to request relief

A statement not filed by May 7 carries a penalty of 10% of the assessed value of the unreported taxable property. The penalty is based on the assessed value of the property, not on the tax you owe, so a late filing can cost far more than the statement itself.

You can ask for the penalty to be removed. Apply to the county board of equalization or assessment appeals board and show reasonable cause and circumstances beyond your control. Your application must be made within the time allowed for assessment reduction applications. That deadline is set by the county, so ask the assessor or the board for it. Do not assume relief will be granted.

Who signs the statement

The statement is signed under penalty of perjury, so the person signing must be confident the figures are accurate.

• Individual or sole proprietor: The owner signs.
• Corporation: An officer signs, or an employee or agent designated in writing by the board of directors signs. Keep that written designation on file.

How to file, step by step

1. Find your county assessor's business property statement page. Each county sets its own process, so do not use another county's portal or fee information.
2. Get the current-year form and instructions. Confirm that the version you use is the one your county accepts.
3. List each taxable asset at cost. Include the acquisition details the form requests, and separate out inventory and software only as your county allows.
4. Apply any low-value exemption your county offers. Ask the assessor how it applies, since the amount varies.
5. Sign the statement. A corporate filer must use an authorized signer.
6. File by 5 p.m. on April 1. Submit it in a way your county accepts, or mail it with a postmark on or before that date. Keep proof of filing.

Common mistakes to avoid

• Treating May 7 as the deadline. April 1 at 5 p.m. is the due date. May 7 is when the penalty applies.
• Filing the wrong return. This statement goes to the county assessor. It is not your state income tax return and it is not your sales tax return.
• Counting only new purchases. Older equipment, including items bought used, still counts toward the $100,000 threshold.
• Waiting for a letter. The assessor can assess property without a request, so an unfiled statement can leave you with an estimated assessment.
• Assuming last year's answer applies. Forms, exemptions, and county practices can change, so check the current year's requirements.

Where this fits in your California setup

The business property statement is one piece of a larger set of registrations. Register your entity with the California Secretary of State through its Business Programs Division. California has no general statewide business license. Register with the CDTFA if you sell taxable goods, which requires a seller's permit that is free. Register with the EDD if you have employees. Most cities charge a local business tax or registration certificate, and there is no common formula, so the right answer depends on your city. Counties license only regulated activities.

Keep the county property statement separate from your state filings. For example, an LLC's $800 minimum annual franchise tax goes to the Franchise Tax Board and has nothing to do with the county assessor. For that side of your obligations, see our California business taxes guide.
