Robert W. Barney, a New Hampshire resident, appeals from a judgment of the Superior Court, York County, affirming a decision of the State Tax Assessor that denied a refund of his Maine income tax for the years 1980 and 1981. Barney challenges the authority of the State to tax his income earned at the Portsmouth Naval Shipyard, a federal enclave within Maine, on the alleged ground that it has not regained the jurisdiction to tax there that it ceded to the federal government in 1863. He further argues that the Privileges and Immunities Clause of Article IV of the United States Constitution bars Maine from prorating his deductions and exemptions according to the ratio of his Maine-earned to total income. Finding no merit in either contention, we affirm the judgment.
Appellant’s first contention is disposed of by our decision in
Morse v. Johnson,
Barney and his wife earned in Maine 74% of the “adjusted gross income” declared on their federal tax return in 1980, and 72.5% in 1981. Accordingly, they were permitted by 36 M.R.S.A. §§ 5144-A and 5145
1
to deduct and exempt on their Maine
*225
income tax returns only 74 and 72.5 percent respectively of the deductions and exemptions they would have been allowed as residents by 36 M.R.S.A. §§ 5125 and 5126 in those years. They were, of course, only required to pay tax to Maine on the portion of their income earned in Maine, since their New Hampshire income is constitutionally beyond this State’s reach.
Shaffer v. Carter,
Concluding that Maine thereby denied them “substantial equality of treatment” with its own residents, without a justification satisfying the ideal of interstate comity enforced by the Privileges and Immunities Clause,
Austin v. New Hampshire,
We do not agree with the appellant that Maine’s scheme imposes a higher effective rate of tax on non-residents than on similarly situated residents. A resident and a non-resident are “similarly situated” when they have the same total income. Maine prorates deductions and exemptions exactly in proportion to the share of total income that it constitutionally may tax. This ensures that, like the non-resident in
Shaffer v. Carter,
the taxpayer is “called upon to make no more than his ratable contribution to the support of the state government.”
Austin,
In arguing that Maine must allow him the deductions and exemptions taken by a resident with the same Maine adjusted gross income, irrespective of how much other income he has, the appellant misapprehends the nature of deductions and exemptions. They are nothing but tax benefits, without any independent existence. The extent of Barney’s eligibility for them is properly linked to the extent of his liability for taxes.
The United States Supreme Court has held that a State need not allow deductions not incurred in producing income within the State.
Shaffer v. Carter,
The same approach is taken with “personal exemptions,” tax benefits that compensate for the cost of living, not the cost of producing income. While Maine may not entirely deny exemptions to all non-resident taxpayers,
Travis v. Yale & Towne Mfg. Co.,
The entry is:
Judgment affirmed.
All concurring.
Notes
. 36 M.R.S.A. § 5144-A provides that,
[t]he itemized deductions of a non-resident individual shall be determined in accordance with the provisions for a resident individual as contained in section 5125 and multiplied by a percentage arrived at by dividing the non-resident's adjusted gross income from sources within this State by his adjusted gross income he would be required to report if he were a resident.
36 M.R.S.A. § 5145 provides that,
[a] non-resident individual shall be allowed the personal exemptions allowed to resident individuals under section 5126, multiplied by *225 a percentage arrived at by dividing the nonresident individual's adjusted gross income from sources within this State by his adjusted gross income he would be required to report if he were a resident.
. Article IV, Section 2, Clause 1 of the United States Constitution provides that "[t]he Citizens of each State shall be entitled to all Privileges and Immunities of Citizens in the several States.”
"For purposes of analyzing a taxing scheme under the Privileges and Immunities Clause the terms ‘citizen’ and ‘resident’ are essentially interchangeable.”
Austin v. New Hampshire,
. Several States have followed these decisions in denying non-residents
any
deductions not connected with producing income within the taxing State.
