Opinion
Plaintiffs Richard Haman, James Blum, Otto Krasch, Thomas Webster and Hunter’s Offshore Enterprises, filed suit to recover the excess of property tax they paid on their fishing boats for the calendar year 1968 over the amount they would have been requirеd to pay if their boats had been registered in California. The trial court found for the county, and all plaintiffs have appealed.
Until 1967 all fishing boats in Humboldt County were assessed at 24 percent of actual cash value. In 1967 the Legislature enacted section 227 of the Revenue and Taxation Code, 1 which lowered the assessment level for fishing boats registered in California to 1 percent of their actual cash value. Such registration is handled by the federal government, аnd provides one basis for proving that a boat has a tax situs within the county. Under the federal statute, a boat should be registered at the port nearest the residence of the owner. 2
Plaintiffs were residents of California during 1968, but had previously *925 registered their boats at pdrts in Oregon, Washington, and Alaska. Apparently, the boats were registered in California after the lien date in 1968. Plaintiffs concede that their boats had a tax situs in Eureka in 1968. 3 Since their boats were not registered in California, the county assessor demanded that they pay taxes aggregating $5,230.07 based on the normal assessment at 24 percent of actual cash value. Had they qualified under section 227 of the Revenue and Taxation Code, their aggregate tax would have been $248.50. They paid under protest.
At the trial there was evidence that the operation of fishing boats registered in other states in no way differed from that of boats registered in California. Plaintiffs had to satisfy the same licensing requirements and obey the same regulations as to amount of catch within state waters. The county conceded that the only difference between California-registered boats and boats registered in other states is the fact of registration. The boat owners contend that this classification violates the equal protection clause of the Fourteenth Amendment.
At the outset we must recognize that since we are dealing with a tax measure the state is to be аccorded very great latitude.

It is also clear that administrative difficulties can justify different treatment under a tax statute. In

There are, however, limits to the latitude afforded a state in demanding taxes. The equal protection clause applies to tax measures.

The discrimination between residents owning fishing boats documented in California and residents owning fishing boats documented in other states may not be justified on either the ground that the tax will promote local industry or the ground that it tends to eliminate doublе taxation. The place of registration with the federal government does not relate to the operation of the fishing boats. By placing the greater tax on the foreign documented boat, the tax, if anything, would tend to drive industry away from California. As to double taxation, the boat documented in another state and used in California faces a greater risk of double taxation than the boat documented in this state and used here.
The principal justification proffered by the county for the discrimination is that it is expensive to prove that a boat registered in another state is used in this state and is owned by a resident. Although, as pointed out above, administrative convenience may furnish a basis for discriminatiоn as to taxes in a proper case, we are satisfied that in the instant case the difference in rates is so great that it may not be upheld.

Anderson,
In fixing the аssessment the burden on the assessor is the same whether or not the boat is documented in California or another state. He must first value the boat whether the assessment rate is 24 percent or 1 percent. As the county points out, the burden on the assessor in determining whether the property is subject to tax is reduced when the boat is docu *928 mented in California because he may then merely check the federal records. As to boats documented in other states, the assessor must check the harbor and determine the residence of the owner of boats found there. However, as to boats found to be taxable, ■ this cost cannot justify the huge difference in assessment. Although the assessor may incur substantial additional expense with regard to boats ultimately determined not to have a tax situs in California, this cost is part of the enforcement costs of the entire statute and attributable to all boats subject to tax; the cost must be incurred even if thе assessor ultimately concludes that none of the boats checked have a California tax situs, and such cost may not be fairly attributed solely to the boats found subject to tax which were registered in other states. In the circumstancеs the great difference in assessment percentages may not be upheld on the grounds of administrative convenience or expense.
In cases involving invalid differentials in tax treatment, the court has the
power
to eliminate the discriminatory treatment either by granting those taxpayers, who have been assessed the higher rate, a refund based on the difference between the lower rate and the one under which they were assessed, i.e., taxing all vessels at 1 percent, or by providing that in the future the board of equalization adjust the assessment rolls so that the higher rate will be applied to all like taxpayers.
(Security-First Nat. Bk.
v.
County of L. A.,
The main purpose of the 1 percent assessment is obviously to aid California’s ailing fishing industry. The statute requires that as well as having a port of documentation within the state, the vessel must be “. . . engаged or employed exclusively; (1) In the taking and possession of fish or other living resource of the sea for commercial purposes, . . .” (Italics added.) The only other means in which a vessel can be employed and still qualify under section 227 is as an oceanograрhic research *929 vessel. The use of a vessel for fishing or for oceanographic research provides a significant basis for the legislative determination to distinguish those vessels from others. (Cf. Cal. Const., art. XIII, § 4 (exemption of certain vеssels from local taxation).)
We conclude that the legislative intent is properly carried out by holding invalid subdivision (a) of section 227, which requires that the port of documentation be within this state, and by upholding the balance of the sectiоn. Accordingly, plaintiffs are entitled to a refund.
The judgment is reversed with directions to enter judgment for plaintiffs in accordance with the views expressed above.
Notes
Section 227 provides that:
“A documented vessel, as defined in Section 130, shall be assessed at one percent (1 %) of its full cash value only if:
“(a) The port of documentation is in this state.
“(b) The vessel is engaged or employed exclusively:
“(1) In the taking and possession of fish or other living resources of the sea for commercial purposes, or
“(2) In instruction or research studies as an oceanographic research vessel.”
Section 130 provides that a documented vessel is “any vessel which is required to have and does have a valid marine document issued by the Bureau of Customs of the United States . . . .”
46 United States Code section 17 provides that every vessel registered shall be registered as belonging to a stated port, “which port shall be deemed to be that at or nearest to which the owner, if there be but one, or if more than one, the husband or acting and managing owner of such vessel, usually resides.”
Prоvision is made for change in the home port designation from time to time with the approval of the Commissioner of Customs. (46 U.S.C. § 18.)
Section 1138 of the Revenue and Taxation Code provides: “Vessels documented outside of this State and plying in whole or in part in its waters, the owners of which reside in this State, shall be assessed in this State.”
