What is MAF800?
The MAF-800 Vessel/Aircraft Owner Information Report is the San Diego County Assessor/Recorder/Clerk form on which a boat or aircraft owner reports ownership details so the Assessor's Office can send the proper property statement to file timely.
The form is not the property statement itself. It explains the rule behind it: under Section 441 of the California Revenue and Taxation Code, any person who owns taxable personal property, such as a boat or aircraft, on the January 1 lien date must file a signed property statement with the Assessor's Office. The MAF-800 gives the office the information it needs to send you that statement.
It has two blocks. Vessel Information asks for the official number (CF or USCG documentation), name, builder, model, year built, length, engine data, purchase price and date, the marina and slip, the date the vessel first moved to San Diego County, and whether you live aboard as your primary residence. Aircraft Information asks for the F.A.A. registration number, make, model, year, purchase price and date, and the aircraft's location.
Under Section 451 of the California Revenue and Taxation Code, the information on the statement is confidential and not a public document. The Assessor's forms page lists other vessel and aircraft forms, such as MAF-309, Notification of Sale/Loss/Permanent Removal.
Who needs to file MAF800?
Owners of a boat or aircraft on the January 1 lien date complete the MAF-800 and return it to the San Diego County Assessor's Office. The form asks you to complete it as a boat or aircraft owner so the office can send you the proper statement to file.
- Vessel owners complete the Vessel Information block.
- Aircraft owners complete the Aircraft Information block.
You do not need to return the form if you have previously done so for your vessel or aircraft; the form says so in a note at the top.
If you live on the vessel as your primary residence, answer Yes to that question and contact the Homeowners Exemption Section of the Assessor's Office at 619/531-5772 to request the claim form. The form also says you can download it from www.sdarcc.com.
Questions about the form go to the Business Division, Marine and Aviation Section, at 858/505-6200 or [email protected]. The form does not describe how someone else may sign for an owner.
When to file MAF800
The form ties its timing to the property statement. The January 1 lien date decides who must file: anyone owning a boat or aircraft on that date must file a signed property statement with the Assessor's Office. To avoid a non-filing penalty, the form says that statement must be filed by May 7. If May 7 falls on a Saturday, Sunday or legal holiday, penalties are applied after the following business day.
The MAF-800 has no due date of its own. You return it so the office can send you the proper statement to file timely, so send it before the May 7 statement deadline. If you have already returned the form for your vessel or aircraft, you do not need to return it again.

Common mistakes to avoid
- Treating the MAF-800 as the property statement. It only asks for your information so the office can send you the proper statement, which must be filed by May 7 to avoid a non-filing penalty.
- Returning the form again after you have already returned it for the same vessel or aircraft; the note at the top says that is not needed.
- Sending the form without a signature and date; the form has a Signature and Date line at the bottom.
- Mailing the form to an e-mail address or phone line; the e-mail address and phone number are for questions, and the form is returned to the office at the printed address.
- Ignoring the live-aboard question. If you answer Yes, the form says to contact the Homeowners Exemption Section at 619/531-5772 to request the claim form.
- Assuming a May 7 falling on a weekend or legal holiday moves the whole deadline; the form says penalties apply after the following business day.
- Leaving the vessel's official number blank when the vessel has a CF or USCG documentation number, or the F.A.A. registration number blank for an aircraft.
