Doesn't seem like this should be so hard to answer. Property tax is the portion that is based on the worth of the vehicle (as opposed to miscellaneous fees). Your California DMV registration is itemized with the License Fee based on the worth of the vehicle. Seems logical, then, that the property tax portion of your vehicle registration is equal to the license fee, but does not include the weight fee, special plate fee, county/district fees, owner responsibility fee, nor smog abatement fee. This is an assumption and not based on any professional advice or knowledge.
