Must a California business file a property statement when the assessor asks, even if every asset was expensed?
The short answer
Yes: a business the assessor asks must file a property statement whatever its asset cost, and expensed equipment is reported at full cost by year acquired. Rev. and Tax. Code section 441(a) requires a signed statement every year from anyone owning taxable personal property with an aggregate cost of $100,000 or more, and from every other owner of personal property "upon request of the assessor." Property tax does not follow book or income tax treatment: the Board of Equalization's prescribed form tells filers to "Include expensed equipment and fully depreciated items" at "100 percent of actual cost," and the assessor values that cost with the Board of Equalization's index and percent good tables (Form BOE-571-L, Schedule A instructions; Assessors' Handbook Section 581). Property that escaped assessment can be assessed for each lien date still open, generally four years back (sections 531, 532(a)), and, on the text of sections 463, 506 and 531, the 10 percent penalty and interest attach only to the years in which a statement was required or requested and not filed (sections 463, 506, 531).
Who files, and what a request changes
Section 441(a) creates two filing duties. The first is automatic: a person owning taxable personal property, other than certain manufactured homes, with an aggregate cost of $100,000 or more for any assessment year "shall file a signed property statement with the assessor." The second is triggered by the assessor: "Every person owning personal property that does not require the filing of a property statement or real property shall, upon request of the assessor," file one. The form the assessor sends repeats the point in its own words, telling the recipient that it must file "regardless of aggregate cost of property" (Form BOE-571-L, Rev. 32 (07-25)). A request is therefore a filing duty, not an invitation, and a business with three laptops and a desk owes a statement once asked.
The assessor need not send a paper form. The Board of Equalization's rule requires assessors to furnish statements and instructions to required or requested filers by mail or electronically, and lets them meet that duty for persons required by law to file by mailing a letter or postcard saying the statement is available on the assessor's website (Cal. Code Regs., tit. 18, section 171(f)). Section 441(a) prescribes no form for the assessor's request, so a letter or postcard asking a business to file, including one that points to an online filing portal, is on its terms a request. The duty also runs only one way: "Failure of the assessor to request or secure the property statement does not render any assessment invalid" (section 441(a)), so a business at or above $100,000 that was never asked was still required to file each year.
The statement is due between the January 1 lien date and 5 p.m. on April 1, declared under penalty of perjury, and the section 463 penalty applies to a statement not filed by May 7 (section 441(b)). A filer may amend for errors and omissions made without willful intent until May 31, without penalty where the original was timely (section 441(i)). Execution matters: a property statement that is unsigned "does not constitute a valid filing," and the section 463 penalty for failure to file applies to it (Cal. Code Regs., tit. 18, section 172(e)).
Not filing after a request has two consequences. Where a person "fails to comply with any provision of law for furnishing information" required by section 441 after a written request, the assessor estimates the value of the property from the information it has and assesses it (section 501). And a person who "is requested by the assessor to make an annual property statement" and does not file within the section 441 time limit draws "a penalty of 10 percent of the assessed value of the unreported taxable tangible property," which "shall be added to the assessment made on the current roll" (section 463(a)). Added to the assessed value, the penalty raises the tax by 10 percent. The county board of equalization or assessment appeals board may abate it on a timely written application if the failure "was due to reasonable cause and circumstances beyond the assessee's control" (section 463).
Why expensing does not take equipment off the roll
The property tax measures property, not deductions. "Every assessor shall assess all property subject to general property taxation at its full value" (section 401), and personal property has no base year value: it is valued afresh on each lien date. A business that expenses a laptop under a federal election, or never capitalizes purchases below its book threshold, has made an income tax or accounting decision; the laptop on the desk on January 1 is still taxable tangible personal property used in a business. The statement "shall show all taxable property owned, claimed, possessed, controlled, or managed" by the filer (section 442(a)), and it may be required to show the property's cost where the filer knows it or can obtain it from its records (section 445).
The form spells out what follows. Schedule A of Form BOE-571-L asks for equipment cost "segregated by calendar year of acquisition," instructs filers to "Include expensed equipment and fully depreciated items," and asks for "100 percent of actual cost," including "excise, sales, and use taxes, freight-in, installation charges, and all other relevant costs" (Form BOE-571-L, Schedule A and Part II instructions). The Board of Equalization's own course for appraisers makes the same point from the other side: filers report full cost and "do not deduct investment credits, trade-in allowances or depreciation," and an item fully depreciated for accounting or tax purposes is not thereby without value, since that "does not mean it does not have value for property tax purposes" (Board of Equalization, Valuation of Personal Property and Fixtures, Lesson 7, Cost and Cost Adjustments).
Cost and acquisition year are inputs, not the answer. The assessor converts each year's cost to a value estimate with the equipment index, percent good and valuation factor tables the Board of Equalization publishes each year in Assessors' Handbook Section 581 (Letter To Assessors No. 2025/046, December 30, 2025, transmitting the 2026 tables). The percent good factor is selected from the acquisition year and the equipment's economic life (Board of Equalization, Valuation of Personal Property and Fixtures, Lesson 5), and the tables include separate valuation factors for non-production computers. A ten-year-old desk is therefore assessed at a fraction of its cost, and a two-year-old workstation at more of its cost; neither is assessed at the zero the books show.
The same logic places the $100,000 line. Section 441(a) speaks of aggregate "cost," not book value or tax basis, and the form asks for full cost of expensed and fully depreciated items. A business that measures itself against the threshold from its balance sheet, where expensed items appear at nothing, can miss an automatic duty that its property's cost has already triggered.
Three other entries on the statement behave differently. Supplies on hand, such as stationery, office, janitorial and lavatory supplies, are reported on Part II, line 1 "at their current replacement costs," excluding supplies that become a component of a product the business makes or sells. Application software costs are left off under the form's instruction. And inventory is exempt: "business inventories are exempt from taxation" (section 219), but the definition excludes "business machinery or equipment or office furniture, machines or equipment" except when held for sale or lease (section 129), so an office's own furniture and computers never qualify. Nor does the household furnishings exemption help a home-based business: it excludes items "held or used in connection with a trade, profession or business" (section 224).
Leased equipment, borrowed space and tenant improvements
Equipment the business leases is not reported as its own. Part III of the statement lists property belonging to others at the location, including leased, lease-purchase, capitalized lease and vending equipment, with the lessor's name, the year of acquisition, the installed cost and the annual rent, and instructs filers not to include leased items in Schedules A or B unless the final payment has been made (Form BOE-571-L, Part III). Who is assessed depends on the agreement: the form asks whether the lessor or the lessee bears the tax obligation, and the assessor considers the contract but is not bound by it (Form BOE-571-L, Part III). Property leased with an option to purchase for one dollar or other nominal consideration is reported by the lessor unless it qualifies for one of the constitutional exemptions, in which case it is treated as owned by the lessee (section 442(c)).
Improvements to leased space depend on who owns them. The Board of Equalization's handbook states that "Improvements installed by tenants may be assessed to either the landlord (the lessor) or the tenant (the lessee)," that improvements integrated into the building are generally assessed to the landlord on the secured roll, that tenant-owned fixtures are assessed to the tenant on the unsecured roll, and that the assessee is determined by the facts of each case (Assessors' Handbook Section 504, Assessment of Personal Property and Fixtures (October 2002, reprinted January 2015), p. 6). The lease is the first evidence: a clause vesting improvements in the landlord on installation points one way, a clause leaving them the tenant's until surrender points the other. Improvements the business owns go on Schedule B by year of acquisition, split between structure items and fixtures, and Schedule B, line 70 asks for tenant improvements for which the business received allowances during the period and that are not already reported (Form BOE-571-L, Schedule B instructions).
What a first statement after years of silence brings
The statement asks for cost by year of acquisition, so a first filing shows the assessor what stood in the office on earlier lien dates. Section 531 then applies: "If any property belonging on the local roll has escaped assessment, the assessor shall assess the property on discovery at its value on the lien date for the year for which it escaped assessment," at that year's rate. The period is four years after July 1 of the assessment year in which the property escaped (section 532(a)), and an assessment year is "the period beginning with a lien date and ending immediately prior to the succeeding lien date" (section 118). For property on a January 1 lien date, the window closes on July 1 four years later. An escape for the lien date four years before the request is therefore reachable only if the assessor acts before that July 1; later, three prior lien dates remain open. The period is eight years where the 25 percent penalty for willful concealment or misrepresentation is added (sections 502, 504, 532(b)(1)).
Whether an escape year carries a penalty and interest depends on whether a statement was due that year. Section 531's second paragraph provides that property "shall be deemed to have escaped assessment when its owner fails to file a property statement" under section 441, and that "Escape assessments made as the result of an owner's failure to file a property statement as herein provided" are subject to "the penalty and interest imposed by Section 463 and 506, respectively." Interest under section 506 is "three-fourths of 1 percent per month," running from the date the tax would have become delinquent had the property been assessed on time until the escape is placed on the roll. A year in which the business owned $100,000 or more of personal property at cost, or was asked to file, and filed nothing, is a failure to file, and it carries the 10 percent penalty and the interest. A year in which the cost was under $100,000 and no request arrived involved no statement the law required; the property still escaped, and the assessor can still assess it, but the text of sections 463 and 531 ties the penalty and interest to a failure to file a statement that was due. No statute states that negative in words, and a business in that position documents the cost on each lien date to show which side of the line each year fell on.
The first statement itself has to be complete. A statement that "fails to report any taxable tangible property accurately," for instance by reporting nothing because everything was expensed, leaves the unreported property to be assessed with section 506 interest, and with the section 504 penalty if the misreporting was willful or fraudulent (section 531.4). Reporting expensed equipment at cost is the accurate entry, not a concession.
Two rules can make a small office's exposure smaller than it looks. A county board of supervisors may exempt personal property whose full value is so low that the tax would not cover the cost of assessing and collecting it, up to a statutory ceiling of $10,000, set uniformly by class and adopted on or before the lien date for the year it applies to (section 155.20(a), (b), (d)). The level is each county's own, so the ordinance in force for each lien date decides whether a given year's value was exempt. And where escapes are found in an audit under section 469, refunds for property incorrectly assessed in the audited years offset the proposed liabilities, penalties and interest included (section 533).
A worked example
A design studio organized as an LLC has occupied a leased suite in a California county for six years. Every equipment purchase was expensed for its books and its federal return. At acquisition cost, its furniture, workstations, monitors and a large-format printer totaled under $100,000 on each of the first three lien dates and $100,000 or more on the two lien dates before the current year. The landlord paid for the build-out under a lease that vests improvements in the landlord, so the studio owns no improvements. In February of the current year it receives a postcard requesting a statement for the January 1 lien date.
The studio files by April 1, listing each year's purchases at full cost in Schedule A, its supplies at replacement cost on line 1, and its leased copier in Part III. With invented figures that are not the Board of Equalization's tables, the county's factors value the equipment at $58,000 for the current lien date and at $55,000, $65,000 and $60,000 for the three prior lien dates, oldest first, and the combined rate is 1.1 percent in each year. The current year's tax is $638. The assessor's escape notices arrive in August, after the window for the lien date four years back has closed, so three prior years are open.
The oldest open year, when the studio's cost was under $100,000 and no request had been made, carries escape tax of $605 and, on the text of sections 463 and 531, no penalty or interest. The next two years were years of automatic filing duty. For the lien date two years back, the 10 percent penalty adds $6,500 to the $65,000 value, for tax of $786.50, and interest at three-fourths of 1 percent a month on that tax, from the August 31 on which it would have gone delinquent to an autumn enrollment, about 26 months, adds roughly $153. For the most recent prior year, the penalty brings the tax to $726, and about 14 months of interest adds roughly $76. The prior-year total is about $2,350, of which about $370 is penalty and interest, all of it from the two years in which a statement was due and not filed. Had the studio's cost crossed $100,000 earlier, every open year would carry the same penalty and interest.
Two items remain open to the studio: an abatement application for each penalty year on a showing of reasonable cause (section 463), and a value challenge for any lien date where the assessor misread an acquisition year or applied the wrong economic life to a class of equipment.
Notices, appeals and payment
No escape assessment may be enrolled until 10 days after the assessor mails or delivers a notice of the proposed amount for each tax year (section 531.8). An application to reduce it is filed within 60 days after the mailing date printed on the notice of assessment or its postmark, whichever is later, or, in Los Angeles County and counties that have adopted the alternative, the mailing date printed on the tax bill (section 1605(b), (c)). Tax added to the unsecured roll after July 31, where tenant-owned property is usually assessed (AH 504, p. 6), becomes delinquent at the end of the month after enrollment, with a 10 percent delinquent penalty (section 2922). The library's article on construction in progress that the assessor never enrolled covers escape limitation rules, waivers and installment payment in more depth.
Practice notes
The sound sequence on receiving a request starts with the fixed asset detail, not the balance sheet: every item at the location on January 1, expensed and fully depreciated items included, at full cost with tax, freight and installation, by calendar year of acquisition, with disposals removed. Leases are read for two questions, who owns the improvements and whether any equipment lease is a nominal purchase lease. The statement is signed by an authorized signer and filed by April 1. The same detail is then run backward: for each prior lien date still open, the aggregate cost on that date and whether a request was made, which together decide whether that year carries the section 463 penalty and section 506 interest or escape tax alone, and whether the county's low-value exemption covered it. A business that never filed and suspects its cost has been above $100,000 for some time weighs the open years before the assessor asks, since each July 1 closes one. When escape notices arrive, the values are checked against the reported cost and acquisition years, an abatement application is considered for each penalty year, and the 60-day application window is calendared from the mailing date.
