The State Tax Assessor, acting through the Bureau of Taxation, determined that alimony paid by David M. Gordon, a nonresident taxpayer, could not be deducted as an adjustment in computing Gordon’s Maine adjusted gross income. Upon the taxpayer’s petition for judicial review pursuant to 36 M.R.S.A. § 151 (Supp.1982-1983) and 5 M.R.S.A. §§ 11001-11002 (1979 & Supp. 1982-1983), the Superior Court, Kennebec County, reversed the administrative decision and the Bureau appeals to this Court. We affirm the judgment of the Superior Court.
The facts of this case are undisputed. At all relevant times Gordon was a resident of New Hampshire. He derived his entire income from his sole employment at the Portsmouth Naval Shipyard in Kittery, Maine. Gordon filed a Maine Income Tax Return for the 1980 calendar year. He claimed a refund of $316.19. The Assessor, however, disallowed as a deduction alimony paid by Gordon in 1980 and adjusted Gordon’s return accordingly. The adjustment resulted in a balance due of $15.86.
Following a hearing on Gordon’s request for reconsideration, the Assessor denied relief, apparently on the basis of a Bureau *58“policy”1 and on the ground that 36 M.R. S.A. §§ 5140 and 5142 (1978) do not permit nonresidents to deduct alimony payments as an adjustment on their Maine income tax returns. Gordon paid the assessment and appealed to the Superior Court.
The Superior Court correctly found that the “policy” applied by the Bureau was not established by the record and is not stated in Maine tax laws. The Superior Court incorrectly determined, however, that 36 M.R.S.A. § 5142 had “no relevance to these proceedings.” The Superior Court then decided that the Bureau could not constitutionally deny the alimony deduction to a nonresident taxpayer while allowing the alimony deduction to residents. The court ordered a refund of the deficiency paid and a refund of the amount originally claimed by Gordon.2
The Maine statutes, pertinent to this appeal, relating to the computation of Maine adjusted gross income for nonresidents are found in 36 M.R.S.A. §§ 5140 and 5142 and provide as follows:
§ 5140. Nonresident individuals — taxable income
The taxable income of a nonresident individual shall be that part of his federal adjusted gross income derived from sources within this State determined by reference to section 5142 less the deductions and personal exemptions provided in this chapter.
§ 5142. Adjusted gross income from sources in this State
1. General. The adjusted gross income of a nonresident derived from sources within this State shall be the sum of the following:
A. The net amount of items of income, gain, loss, and deduction entering into his federal adjusted gross income which are derived from or connected with sources in this State including (i) his distributive share of partnership income and deductions determined under section 5192 and (ii) his share of estate or trust income and deductions determined under section 5176, and
B. The portion of the modifications described in section 5122 subsections 1 and 2 which relate to income derived from sources in this State, including any modifications attributable to him as a partner.
2. Attribution. Items of income, gain, loss, and deduction derived from or connected with sources within this State are those items attributable to:
A The ownership or disposition of any interest in real or tangible personal property in this State; and
B. A business, trade, profession or occupation carried on in this State.
36 M.R.S.A. §§ 5140, 5142(1)-(2) (1978).
Based on these statutory provisions the Bureau argues that for any federal above-the-line deductions3 to qualify as adjustments in computing Maine adjusted gross income for nonresidents, they must be “attributable” to an occupation “carried on in this State.” Although the Bureau concedes that Gordon’s alimony payments are related to his Maine income in the sense that the Maine income is the source of the payments, it contends that to be “attributable” to his occupation the payments must be caused by that occupation, such as a trade or business expense. If Gordon’s position were correct, the Bureau argues, every personal expenditure of a nonresident taxpayer would qualify as an item attributable to the taxpayer’s Maine trade or occupation. The Bureau’s argument overlooks the fact that we are concerned only with those items of expenditure already determined to be allowable above-the-line deductions for federal in*59come tax purposes. Viewed as such, and reduced to the portion attributable to a Maine occupation, these deductions do not produce what the Bureau claims would be an absurd result.
Confusion arises from the Legislature’s commingling of the definition of items of income and gain with items of loss and deduction. It may be inartful to refer to a deduction as an item attributable to an occupation carried on in this state when its only connection is that the occupation is the source of the income from which the deductible item is derived. Nevertheless, we are convinced that is exactly what the Legislature intended. Above-the-line deductions of alimony payments from federal adjusted gross income are to be allowed to the extent that they are payments made possible by income earned in Maine. Such deductions are apportioned by the percentage related to income earned in Maine. This pattern of apportionment is apparent throughout the Maine Income Tax Law. 36 M.R.S.A. §§ 5101-5341 (1978 & Supp.1982-1983).
For example, section 5142(1)(B) specifically includes the portion of the modifications described in section 5122(1) and (2),4 which relate to income derived from sources in this state. Sections 5143-A (standard deduction),5 5144-A (itemized deductions),6 and 5145 (personal exemptions)7 all permit *60below-the-line adjustments in the same proportion that Maine adjusted gross income bears to federal adjusted gross income. Section 5142(6)8 provides that items of business income and deduction be determined under. Chapter 821, 36 M.R.S.A. §§ 5210-5211 (1978 & Supp.1982-1983), which provides generally for apportionment in relation to the percentage of business activity occurring within this state. The Maine nonresident tax form [Schedule NR] and instructions apparently extend this apportionment concept to all above-the-line adjustments. Line 5 of Schedule NR calls for the taxpayer to enter total moving expenses from line 23 of his federal return and then compute the Maine adjustment based upon the percentage that Maine income bears to total income. Line 6 of Schedule NR calls for the taxpayer to enter total employee business expense from line 24 of his federal return and then figure “any portion of this amount that pertains to Maine.” Line 7 calls for the taxpayer to enter amounts from lines 25 through 29 of his federal return relating to (a) payments to an IRA (line 25), (b) payments to a Keogh retirement plan (line 26), (c) interest penalty on early withdrawal of savings (line 27), (d) alimony paid (line 28), and (e) disability income exclusion (line 29), and then figure “any portion that pertains to Maine.” Clearly not all of these adjustments are “business-related expenses” or “caused by [the taxpayer’s] occupation” as the Bureau claims they must be. We think they are, however, items of deduction related to Maine in the sense that Maine is the source of the income.
Our interpretation is consistent with the overall legislative purpose, as well as with the plain meaning of the statute. Unless and until the Legislature provides otherwise, the apportionment principle will apply to alimony payments. Because Gordon’s income is totally derived from his Maine occupation, the total of the alimony payments is allowable as a deductible adjustment in determining Maine adjusted gross income.9

Judgment affirmed.
GODFREY, NICHOLS and WATHEN, JJ., concurring.
.The Bureau stated in its letter to Gordon: “The Bureau does not tax alimony received by a nonresident, therefore, we take the position that we do not allow the deduction of the alimony paid by a nonresident.”
. The Bureau raises no issue on appeal concerning the amount of the refund so ordered.
. Adjustments entering into the computation of adjusted gross income are commonly referred to as above-the-line deductions.

. 36 M.R.S.A. § 5142(6) (1978) reads as follows:
6. Apportionment and allocation. If a business, trade, profession or occupation is carried on partly within and partly without this State, the items of income and deduction derived from or connected with sources within this State shall be determined as allocated or apportioned to this State under chapter 821 or in the case of the rendering of purely personal services by an individual under regulations to be prescribed by the assessor.
. We do not reach and express no opinion on the constitutional implications, if any, of disallowing an adjustment for alimony paid by nonresidents, while permitting such an adjustment for Maine residents.
