What is BOE-571-D?
Form BOE-571-D, Supplementary Schedule for Reporting Monthly Acquisitions and Disposals of Property, is the Los Angeles County Assessor's supplement to Schedule B of the Business Property Statement, listing by month the property acquired and disposed of.
The printed title of the form reads "Supplemental Schedule for Reporting Monthly Acquisitions and Disposals of Property Reported on Schedule B of the Business Property Statement." The Assessor's forms page lists it as BOE-571-D / B-44, and the form carries the revision marks REV. 27 (05-25) and B-44 (REV. 10-25).
The form has an owner name, mailing address and location of property block, then two sides of a table. The Additions side records the column number from Schedule B, the month and year of acquisition, a description and the cost. The Disposals side records the column number, the month and year of disposal, a description and the cost. Page 2 repeats the table and adds a Remarks area. The form carries the printed notice "This statement subject to audit."
It differs from the other supplemental schedules on the Assessor's list, such as the schedules to Form 571-L for specific industries: those serve particular businesses, while this one reports monthly additions and disposals.
Who needs to file BOE-571-D?
The form is for owners of business property who have acquisitions or disposals to report from Schedule B of the Business Property Statement. Its instructions say to report all acquisitions and disposals reported in Columns 1, 2, 3 or 4 on Schedule B for the period January 1, 2025 through December 31, 2025, and to write the applicable column number in the space provided.
Specific situations the form addresses:
- Additions, including transfers-in: report the former property address, the date of transfer, and the original date and cost of acquisition.
- Completed construction: only completed projects belong on the Additions side. A project that is not yet functional or operational is reported as construction-in-progress instead.
- Completed construction previously reported as construction-in-progress on your 2025 property statement: identify it on a separate schedule attached to the form.
- Disposals: report the disposal date and method, and the names and addresses of purchasers when items are sold or transferred.
The form prints nothing about who may sign for the owner.
When to file BOE-571-D
The schedule covers the period January 1, 2025 through December 31, 2025, and it is completed for the acquisitions and disposals that appear in Columns 1, 2, 3 or 4 of Schedule B for that period. It is a supplement to the Business Property Statement, so it is prepared alongside Schedule B rather than on a calendar of its own. No separate due date is printed on the form, and the Assessor's forms page does not give one for it. Check the Business Property Statement and the Assessor at https://assessor.lacounty.gov/forms for the filing date that applies to the statement it supplements.
Documents you need
- A separate schedule describing each item and cost of completed construction as previously reported as construction-in-progress on your 2025 property statement, attached to BOE-571-D, only if you have such completed construction.
How to fill out BOE-571-D
Enter owner and property details
Fill in the OWNER NAME, MAILING ADDRESS and LOCATION OF PROPERTY blocks at the top of page 1.
Confirm the reporting period
Report all acquisitions and disposals shown in Columns 1, 2, 3 or 4 of Schedule B for January 1, 2025 through December 31, 2025.
Record the Schedule B column
In the From Column Number space of each row, write the Schedule B column (1, 2, 3 or 4) where the item was reported.
Describe each addition by month
On the Additions side, enter the month and year of acquisition and describe the property. Include transfers-in.
Enter the total acquisition cost
In the Cost column, enter the total acquisition cost, including excise, sales and use taxes, freight-in and installation charges. For transfers-in, also give the former property address, date of transfer, and original date and cost of acquisition.
Report only completed projects
List a project as an addition only when it is completed, meaning functional or operational. Otherwise report it as construction-in-progress.
Identify finished construction
If construction was reported as construction-in-progress on your 2025 property statement, describe the items and costs as previously reported on a separate schedule and attach it to BOE-571-D.
Complete the Disposals side
For each disposal, enter the Schedule B column, the month and year of disposal, a description and the cost. Give the disposal date and method (transfer, scrapped, abandoned, sold, etc.), plus purchaser names and addresses for items sold or transferred.
Use page 2 and Remarks
Continue the Additions and Disposals tables on page 2 if you need more rows, and add any explanation under REMARKS.
Review and download the PDF
Check every column number, month, description and cost against Schedule B, then download or print the completed PDF from FillingPDF and keep it with the Business Property Statement.
How to submit BOE-571-D
The form prints no mailing address, portal or in-person instruction, so it follows the filing of the Business Property Statement whose Schedule B it supplements. The Assessor's forms page, https://assessor.lacounty.gov/forms, lists BOE-571-L as the Business Property Statement and BOE-571-D / B-44 as this schedule. Confirm with the Los Angeles County Office of the Assessor how and where the statement and its schedules are filed.
If you have completed construction that was previously reported as construction-in-progress, attach your separate schedule describing it to BOE-571-D, as the form instructs. FillingPDF lets you fill out and download the PDF; submission follows the Assessor's channels.
Common mistakes to avoid
- Reporting a project on the Additions side before it is complete; the form says only completed projects belong there and others are reported as construction-in-progress.
- Leaving out the column number from Schedule B (1, 2, 3 or 4) for an addition or disposal.
- Entering an acquisition cost without excise, sales and use taxes, freight-in or installation charges, which the instructions say to include.
- Listing a transfer-in without the former property address, the date of transfer, and the original date and cost of acquisition.
- Reporting a sold or transferred item without the disposal date, the method of disposal and the purchaser's name and address.
- Omitting the separate schedule for completed construction that was reported as construction-in-progress on the 2025 property statement.
- Reporting items for a period other than January 1, 2025 through December 31, 2025.
