WILLIAM R. BERKLEY ET AL. v. GENE GAVIN, COMMISSIONER OF REVENUE SERVICES, 253 Conn. 761

Opinion VERTEFEUILLE, J. The plaintiffs, William Berkley and Marjorie Berkley, appeal from the judgment of the trial court dismissing their appeal from the assessment by the defendant, the commissioner of revenue services, against the plaintiffs of an additional $393,263.01 in state income taxes for the 1994 taxable year.

The principal issues in this appeal are: (1) whether the federal tax benefit rule is incorporated into the definition of “adjusted gross income” contained in General Statutes § 12-701 (a) (19); and (2) if so, whether the plaintiffs are entitled to claim a deduction under the tax benefit rule due to the pass-through of certain losses incurred by subchapter S corporations of which William Berkley was a shareholder, even though the plaintiffs previously had avoided paying $1,297,189.63 in Connecticut capital gains, dividends and interest taxes as a result of those same passed-through losses.

We conclude that the federal tax benefit rule is incorporated into the definition of adjusted gross income contained in § 12-701 (a) (19). We further conclude that the plaintiffs had already received a tax benefit due to the aforementioned losses by virtue of the resultant reduction in their 1988,1989, and 1990 federal adjusted gross income, which allowed them to avoid paying $1,297,189.63 in Connecticut capital gains, dividends and interest taxes. Therefore, they were not entitled to claim such a benefit a second time on their 1994 Connecticut income tax return.

We therefore affirm the judgment of the trial court. The parties in this case have stipulated to the following relevant facts. The plaintiffs are a married couple residing in Greenwich. William Berkley was a shareholder in three S corporations: Farm Acquisition Corporation (Farm Acquisition), Interlaken Grove Investors, Inc. (Interlaken Grove), and Caring Communities, Inc. (Caring Communities).

Two of those corporations, Farm Acquisition and Caring Communities, reported ordinary losses on their 1988, 1989, and 1990 federal income tax returns and the third corporation, Interlaken Grove, reported ordinary losses on its 1989 and 1990 tax returns. Pursuant to 26 U.S.C. § 1366 (a) (l), the plaintiffs deducted William Berkley’s pro rata share of the losses reported by Farm Acquisition and Caring Communities on their federal income tax returns for those three years, and his pro rata share of the losses reported by Interlaken Grove for the 1989 and 1990 tax years.

William Berkley’s bases in the stock of those three corporations then was reduced by the amount of the deductions. See 26 U.S.C. § 1367 (a) (2). During 1988, 1989 and 1990, Connecticut imposed a tax on capital gains, dividends and interest income (capital gains tax) pursuant to General Statutes §§ 12-505 through 12-522, but did not tax any other income. For each of those years, the tax rates on capital gains, dividends and interest income were tied to the taxpayer’s federal adjusted gross income.

If, however, a taxpayer’s federal adjusted gross income fell below a certain level, that taxpayer had no obligation to pay Connecticut’s capital gains tax. As a result of the losses passed through the three S corporations in which William Berkley was a shareholder, the plaintiffs’ federal adjusted gross income for the tax years 1988,1989 and 1990 was negative. Accordingly, the plaintiffs paid no state capital gains tax for those three years.

If the plaintiffs’ federal adjusted gross income for those years had not been reduced by their deduction of the pass-through losses from the three S corporations, the plaintiffs would have owed a total of $1,297,189.63 in state capital gains taxes for those three years. For the 1994 tax year, the plaintiffs reported “worthless stock” losses for federal income tax purposes with respect to William Berkley’s stock in all three S corporations. At that time, his bases in the stock of the three S corporations had been reduced to $3,623,671.

The federal tax code allowed the plaintiffs to deduct the adjusted bases of $3,623,671 from their 1994 long-term capital gains reported in their 1994 federal income tax return. The plaintiffs’ federal adjusted gross income for the 1994 tax year was $8,342,817. In October, 1995, the plaintiffs timely filed a “Form CT-1040 Connecticut Resident Income Tax Return” for the 1994 tax year, on which they reported an overpayment of $496,123.

In computing their 1994 Connecticut taxable income, the plaintiffs subtracted from their federal adjusted gross income of $8,342,817, the sum of $9,743,387, representing the aggregate reductions to the bases of the stock held by William Berkley in the three S corporations in 1988, 1989 and 1990. The plaintiffs subsequently agreed to limit the contested basis adjustment to $6,541,489, representing the total basis adjustment excluding depreciation and amortization.

If the plaintiffs’ deduction of the basis adjustment from the Connecticut basis in William Berkley’s S corporation stock in computing their Connecticut adjusted gross income for 1994 were permissible, the plaintiffs would be entitled to a refund of $294,367, plus interest, for the 1994 tax year. In addition, the record reveals the following other relevant facts. In February, 1996, the defendant notified the plaintiffs of a proposed recalculation of their 1994 Connecticut income tax, under which the defendant intended to assess against the plaintiffs an additional liability of $393,263.01.

In April, 1996, the defendant sent a notice of the additional assessment to the plaintiffs. On May 17,1996, the plaintiffs appealed the defendant’s assessment to the Tax Session of the Superior Court. The trial court issued a written memorandum of decision in favor of the defendant.

In that memorandum, the trial court initially concluded that “[t]he tax benefit rule is alive and well in Connecticut.” The trial court further concluded, however, that “the [plaintiffs] avoided paying a Connecticut [capital gains tax] on a substantial amount of income because . . . the pass-through losses of the three S corporations were used in the determination of their federal adjusted gross income for 1989-90.

They are not now entitled to a double benefit by excluding the losses in the determination of the basis of the three S corporations for capital gains purposes in determining their adjusted gross income under the Connecticut personal income tax.” Accordingly, the trial court rendered judgment dismissing the plaintiffs’ appeal. Thereafter, the plaintiffs appealed the trial court’s judgment to the Appellate Court, and we granted the defendant’s motion to transfer the appeal to this court pursuant to General Statutes § 51-199 (

c) and Practice Book § 65-2. On appeal, the plaintiffs argue that, although the trial court properly concluded that the federal tax benefit rule applies to Connecticut’s personal income tax, the trial court improperly concluded that the plaintiffs’ S coiporation losses could not be excluded, pursuant to the tax benefit rule, from the plaintiffs’ Connecticut adjusted gross income. We affirm the judgment of the trial court in both respects. I At the outset, a brief explanation of the federal tax benefit rule is warranted.

The tax benefit rule is “a judicially developed principle that allays some of the inflexibilities of the annual accounting system. An annual accounting system is a practical necessity if the federal income tax is to produce revenue ascertainable and payable at regular intervals. Burnet v. Sanford & Brooks Co., 282 U.S. 359, 365, [51 S. Ct. 150, 75 L. Ed. 2 383] (1931). Nevertheless, strict adherence to an annual accounting system would create transactional inequities. Often an apparently completed transaction will reopen unexpectedly in a subsequent tax year, rendering the initial reporting improper.

For instance, if a taxpayer held a note that became apparently uncollectible early in the taxable year, but the debtor made an unexpected financial recovery before the close of the year and paid the debt, the transaction would have no tax consequences for the taxpayer, for the repayment of the principal would be recovery of capital. If, however, the debtor’s financial recovery and the resulting repayment took place after the close of the taxable year, the taxpayer would have a deduction for the apparently bad debt in the first year under § 166 (

a) of the [Internal Revenue] Code, 26 U.S.C. § 166 (a). Without the tax benefit rule, the repayment in the second year, representing a return of capital, would not be taxable. The second transaction, then, although economically identical to the first, could, because of the differences in accounting, yield drastically different tax consequences. The Government, by allowing a deduction that it could not have known to be improper at the time, would be foreclosed from recouping any of the tax saved because of the improper deduction.

Recognizing and seeking to avoid the possible distortions of income, the courts have long required the taxpayer to recognize the repayment in the second year as income.” Hillsboro National Bank v. Commissioner of Internal Revenue, 460 U.S. 370, 377-79, 103 S. Ct. 1134, 75 L. Ed. 2d 130 (1983). The tax benefit rule may be illustrated further by the following hypothetical example: If a taxpayer is owed $100 in connection with his trade or business and the debtor fails to pay the debt when it is due, the taxpayer may deduct the $100 loss as a bad debt. See 26 U.S.C. § 166 (a) (1).

If the taxpayer’s taxes, are reduced as a result of the deduction (in other words, if he receives a “tax benefit”), and the taxpayer recovers the debt in a subsequent tax year, he must report the $100 as income. This represents the “inclusionary” aspect of the rule. See Allstate Ins. Co. v. United States, 936 F.2d 1271, 1274 (Fed. Cir. 1991). If, however, the taxpayer received no tax benefit from the original deduction, he is not required to report the subsequent recovery, because he never received any tax benefit as a result of the loss. This represents the “exclusionary” aspect of the rule.

See id.; see also 26 U.S.C. § 111 (a) (“[g]ross income does not include income attributable to the recovery during the taxable year of any amount deducted in any prior taxable year to the extent such amount did not reduce the amount of tax imposed by this chapter”). II Having delineated the parameters of the federal tax benefit rule, we now turn to the first issue in this appeal, namely, whether the federal tax benefit rule is incorporated into Connecticut’s definition of adjusted gross income contained in § 12-701 (a) (19).

The trial court concluded that the federal tax benefit rule is incorporated into Connecticut’s personal income tax scheme. The plaintiffs contend that, in this respect, the trial court was correct. The defendant, to the contrary, contends that the federal tax benefit rule is not incorporated into our personal income tax scheme. We agree with the trial court and the plaintiffs. The question of whether the federal tax benefit rule is incorporated into § 12-701 (a) (19) is one of statutory

interpretation, which we review according to well settled principles. “Statutory

interpretation is a matter of law over which this court’s review is plenary. ... In construing statutes, [o]ur fundamental objective is to ascertain and give effect to the apparent intent of the legislature. ... In seeking to discern that intent, we look to the words of the statute itself, to the legislative history and circumstances surrounding its enactment, to the legislative policy it was designed to implement, and to its relationship to existing legislation and common law principles governing the same general subject matter. . . . Doyle v. Metropolitan Property & Casu alty Ins.

Co., 252 Conn. 79, 84, 743 A.2d 156 (1999).” (Internal quotation marks omitted.) Chief of Police v. Freedom of Information Commission, 252 Conn. 377, 386-87, 746 A.2d 1264 (2000). We begin with the language of the statute, which provides that “ ‘[a]djusted gross income’ means the adjusted gross income of a natural person with respect to any taxable year, as determined for federal income tax purposes.” General Statutes § 12-701 (a) (19). This definition is a part of Connecticut’s overall personal income tax scheme. See General Statutes § 12-700 et seq.

Section 12-701 (a) (20) further modifies the definition contained in § 12-701 (a) (19) by enumerating eighteen specific modifications, none of which is relevant to this case, that may be made to a taxpayer’s adjusted gross income. The central question that § 12-701 (a) (19) raises, but does not answer, is whether the phrase “as determined for federal income tax purposes,” means as determined in accordance with federal income tax methodology, or as reported on a taxpayer’s federal income tax return. Although there is no legislative history on this point, an examination of our prior case law leads us to con-elude that the former

interpretation is the correct one, and that, therefore, § 12-701 (a) (19) does incorporate the federal tax benefit rule. We long have held that “when our tax statutes refer to the federal tax code, federal tax concepts are incorporated into state law. The B. F. Goodrich Co. v. Dubno, 196 Conn. 1, 7, 490 A.2d 991 (1985); Yaeger v. Dubno, 188 Conn. 206, 210, 211-12, 449 A.2d 144 (1982); Woodruff v. Tax Commissioner, 185 Conn. 186, 191, 440 A.2d 854 (1981); Peterson v. Sullivan, 163 Conn. 520, 525, 313 A.2d 49 (1972); Kellems v. Brown, 163 Conn. 478, 518-19, 313 A.2d 53 (1972), appeal dismissed, 409 U.S. 1099, 93 S.

Ct. 911, 34 L. Ed. 2d 678 (1973); First Federal Savings & Loan Assn. v. Connelly, 142 Conn. 483, 489-93, 115 A.2d 455 (1955), appeal dismissed, 350 U.S. 927, 76 S. Ct. 305, 100 L. Ed. 811 (1956); McKesson & Robbins, Inc. v. Walsh, 130 Conn. 460, 461-64, 35 A.2d 865 (1944).” (Internal quotation marks omitted.) Harper v. Tax Commissioner, 199 Conn. 133, 139, 506 A.2d 93 (1986).

Although this rule does not require the wholesale incorporation of the entire body of federal tax principles into our state income tax scheme, where a reference to the federal tax code expressly is made in the language of a statute, and where incorporation of federal tax principles makes sense in light of the statutory language at issue, our prior cases uniformly have held that incorporation should take place. Harper v. Tax Commissioner, supra, 199 Conn. 133, is an excellent example of such a scenario.

The issue in Harper was whether patent sales fell within the ambit of the definition of taxable gains contained in General Statutes (Rev. to 1973) § 12-505, as amended by Public Acts 1973, No. 73-356, § l, which expressly defined taxable gains as “net gain as determined for federal income tax purposes . . . .” (Emphasis added.) See Harper v. Tax Commissioner, supra, 139. We therefore referred to the federal tax code’s treatment of patent sales in order to determine whether such sales constituted taxable gains. Id. Harper is not the only case in which we have employed such an approach. See, e.g., The B. F.

Goodrich Co. v. Dubno, supra, 196 Conn. 7 (lack of any reference to federal tax code in text of General Statutes § 12-218 [2] meant court would not incorporate federal tax principles); Woodruff v. Tax Commissioner, supra, 185 Conn. 190-91 (§ 12-505 specifically incorporates “federal income tax scheme”); First Federal Savings & Loan Assn. v. Connelly, supra, 142 Conn. 492 (statutory definition of gross income “ ‘as defined in the federal corporation net income tax law’ ”). It is a generally accepted principle that we construe statutes in accordance with the dictates of logic and common sense. See State v.

Jason B., 248 Conn. 543, 550, 729 A.2d 760, cert. denied, 528 U.S. 967, 120 S. Ct. 406, 145 L. Ed. 2d 316 (1999). On the basis of this principle, we have, in the past, construed general statutory references to the federal tax code as incorporating federal tax principles into our statutes. We see no reason to reverse this policy, and to hamstring our legislature by requiring it to anticipate, and specifically refer to each and every doctrine of federal tax law whenever it concludes that employing federal tax methodology would be beneficial.

We therefore conclude that the phrase “as determined for federal income tax purposes” contained in § 12-701 (a) (19) incorporates the federal tax benefit rule. The defendant advances two principal arguments in support of his claim that the federal tax benefit rule is not incorporated into § 12-701 (a) (19). We find neither of these arguments persuasive. The defendant first contends that this court’s holding in Ruskewich v. Commissioner of Revenue Services, 213 Conn. 19, 566 A.2d 658 (1989), militates against the incorporation of the tax benefit rule into § 12-701 (a) (19).

The issue in Ruskewich was “whether the [plaintiffs could] carry over and deduct a capital loss to calculate net gain on their Connecticut capital gains and dividends tax return when they [had] reported no carryover loss on their federal income tax return for the same taxable year.” Id., 20. In order to decide that issue, the court was required to construe General Statutes (Rev. to 1983) § 12-505 — specifically, the phrase “ ‘after due allowance for losses and holding periods.’ ” Id., 26.

The court concluded that, based on the references in § 12-505 to the federal tax code, the language of § 12-505 at issue properly could be understood only by incorporation of federal tax principles. Id., 26-27. The defendant claims that our incorporation of federal tax principles in Ruskewich was based on the inherent ambiguity of the phrase “ ‘after due allowance for losses and holding periods,’ ” and that, absent that ambiguous language in § 12-505, “[i]t is likely that Ruskewich . . . would have been decided differently . . . .” We do not agree with the defendant’s conclusion.

Although our opinion in Ruskewich seeks guidance from federal tax principles in order to clarify the meaning of § 12-505, it does not set forth a rigid rule requiring ambiguity in our state tax statutes before reference may be made to federal tax law. Indeed, Ruskew-ich expressly relied on the basic premise of Harper v. Tax Commissioner, supra, 199 Conn. 139, namely, that “when our tax statutes refer to the federal tax code, federal tax concepts are incorporated into state law.” (Internal quotation marks omitted.) Ruskewich v. Commissioner of Revenue Services, supra, 213 Conn. 26.

We therefore see no reason to cull from our decision in. Ruskewich additional restrictions on the applicability of federal tax concepts to our state income tax. The defendant’s second claim is that because § 12-701 (a) (20) contains a specific list of the modifications that may be made to a taxpayer’s adjusted gross income; see footnote 8 of this opinion; that , list evidences the legislature’s intent not to allow any other modifications to the adjusted gross income calculation.

This contention ignores the plain language of the statute, which provides that “ ‘Connecticut adjusted gross income’ means adjusted gross income, with the following modifications . . . .” (Emphasis added.) General Statutes (Rev. to 1993) § 12-701 (a) (20), as amended by Public Acts 1993, No. 93-74, § 39, and Public Acts, Spec. Sess., May, 1994, No. 94-4, § 26.

This crucial phrase is itself defined in § 12-701 (a) (19) as “adjusted gross income ... as determined for federal income tax purposes.” It is clear, therefore, that the federal tax benefit rule is incorporated into § 12-701 (a) (19) as a part of the definitional phrase “adjusted gross income,” and not as one of the eighteen modifications set forth in § 12-701 (a) (20). See footnote 8 of this opinion. Therefore, the question of whether the legislature intended that list to be exclusive is irrelevant to our determination of this issue.

In sum, we do not view this case as warranting a departure from our long-standing practice of allowing the legislature to refer to federal tax principles through the use of general referential language. Such a practice is in accord both with common sense, and our canons of statutory construction. We therefore conclude that the federal tax benefit rule is incorporated into the definition of “adjusted gross income” contained in § 12-701 (a) (19).

III We turn next to the final issue in. this appeal, namely, whether the plaintiffs are entitled to claim a deduction under the tax benefit rule due to the pass-through of certain losses incurred by the S corporations of which William Berkley was a shareholder, even though the plaintiffs previously had avoided paying $1,297,189.63 in Connecticut capital gains taxes as a result of those same passed-through losses.

The defendant argues, as the trial court concluded, that the plaintiffs had received a tax benefit from those losses, and therefore were not entitled to claim such a benefit a second time on their 1994 Connecticut income tax return. We agree. It is well settled “that deductions from otherwise taxable income are a matter of legislative grace and hence are strictly construed against the taxpayer. . . . Skaarup Shipping Corporation v. Commissioner, 199 Conn. 346, 352, 507 A.2d 988 (1986); Golf Digest/Tennis, Inc. v. Dubno, 203 Conn. 455, 464, 525 A.2d 106 (1987).

Thus, in order for the taxpayers to prevail in their challenge of the commissioner’s disallowance of these claimed deductions, they must establish clearly and unambiguously the right to claim a deduction .... Golf Digest/Tennis, Inc. v. Dubno, supra, 465.” (Citations omitted; internal quotation marks omitted.) Bolt Technology Corp. v. Commissioner of Revenue Services, 213 Conn. 220, 227-28, 567 A.2d 371 (1989). In this case, the plaintiffs have failed to meet that substantial burden.

Although many of the cases, as well as the statutory codification of the tax benefit rule; see 26 U.S.C. § 111; speak in terms of income that was “deducted” in a prior tax year, actual deduction is not an absolute prerequisite to the applicability of the rule. See Home Mutual Ins. Co. v. Commissioner of Internal Revenue , 639 F.2d 333, 343 n.26 (7th Cir. 1980), cert. denied, 451 U.S. 1017, 101 S. Ct. 3005, 69 L. Ed. 2d 388 (1981) (“[t]he tax benefit rule is not limited to the recoveries of deductions”).

Above all, it bears emphasis that the tax benefit rule “is an equitable doctrine which should be carried to an equitable conclusion. ” Alice Phelan Sullivan Corp. v. United States, 381 F.2d 399, 403 n.5 (Ct. Cl. 1967); see also Hillsboro National Bank v. Commissioner of Internal Revenue, supra, 460 U.S. 377 (“strict adherence to an annual accounting system would create transactional inequities”); 1 J.

Mertens, Federal Income Taxation (1999 Rev.) § 7:26, p.7-77 (“[t]he purpose of the tax benefit rule is not merely to tax recoveries, but to approximate the results produced by a tax system based on transactional rather than annual accounting”). The salient inquiry in any tax benefit case, therefore, must be whether the application of the rule would help to “avoid . . . possible distortions of income”; Hillsboro National Bank v. Commissioner of Internal Revenue, supra, 378; that result from the inflexibilities of an annual accounting system.

In the present case, it is undisputed that because the plaintiffs’ income greatly was reduced by the pass-through of the S corporation losses to William Berkley, the plaintiffs did not have to pay almost $1.3 million in Connecticut capital gains taxes in the 1988, 1989, and 1990 tax years. It also is undisputed that the plaintiffs’ deduction of the pass-through losses from the three S corporations was the sole reason that they were able to avoid paying capital gains taxes for those three years.

Given those two predicate facts, it would violate the purpose and spirit of the tax benefit rule were we to conclude that the plaintiffs have not already received a tax benefit from the pass-through of the S corporation losses. Such a conclusion would have the undesirable effect of allowing the plaintiffs to receive a double benefit from a single set of losses.

Although the plaintiffs make much of the alleged distinction between a deduction under the tax benefit rule, and the reduction in federal adjusted gross income that allowed them to avoid paying Connecticut capital gains taxes, that is a distinction without a difference. The tax benefit rule never has been constrained by such technicalities. Rather, courts generally have viewed it as a practical rule designed to ensure the smooth functioning of our tax system. See Hillsboro National Bank v. Commissioner, supra, 460 U.S. 377.

In this case, the fact that the plaintiffs received a prior tax savings due to their pass-through losses is enough to prohibit them from claiming such a benefit a second time. The judgment is affirmed. In this opinion BORDEN, NORCOTT and PALMER, Js., concurred. General Statutes § 12-701 (a) (19) provides: “ ‘Adjusted gross income’ means the adjusted gross income of a natural person with respect to any taxable year, as determined for federal income tax purposes.” An S corporation is a small business corporation that qualifies for certain tax and financial prerogatives. See 26 U.S.C. § 1361 et seq.

Section 1366 (a) (1) of title 26 of the United States Code provides in relevant part: “In determining the tax under this

chapter of a shareholder for the shareholder’s taxable year in which the taxable year of the S corporation ends . . . there shall be taken into account the shareholder’s pro rata share of the corporation’s “(

A) items of income (including tax-exempt income), loss, deduction, or credit the separate treatment of which could affect the liability for tax of any shareholder, and “(

B) nonseparately computed income or loss.” For the 1988 Connecticut tax year, General Statutes (Rev. to 1987) § 12-506 (a) (1), as amended by Public Acts 1987, No. 87-559, §§ 2 and 3, imposed a tax on a sliding scale on all dividends and interest income, except that no such tax would be imposed unless the taxpayer’s adjusted gross income as determined for federal tax purposes; see General Statutes (Rev. to 1987) § 12-505 (a) (9) for definition of “acljusted gross income”; exceeded $54,000.

Section 12-506 (a) (2) at that time imposed a tax at the rate of 7 percent, except that, under § 12-506 (b), a taxpayer whose adjusted gross income did not exceed a certain level was not subject to such a tax. For the 1989 Connecticut tax year, General Statutes (Rev. to 1989) § 12-506 (a) (1), as amended by Public Acts 1989, No. 89-251, §§ 17 and 203, imposed a tax on a sliding scale on all dividends and interest income, except that no such tax would be imposed unless the taxpayer’s adjusted gross income exceeded $54,000.

At that time, § 12-506 (a) (2), as amended by Public Act 89-251, imposed a tax at the rate of 7 percent on all gains from the sale or exchange of capital assets, except that “the amount of tax payable by any taxpayer under this subdivision (2) with respect to such gains for any taxable year may not exceed an amount equal to five per cent of the adjusted gross income of such taxpayer for such taxable year, as determined for purposes of the federal income tax." For the purposes of this case, the Connecticut dividends, interest and capital gains tax statutes applicable in the 1990 Connecticut tax year imposed the same rates and allowed the same exceptions as those applicable in the 1989 tax year.

See General Statutes (Rev. to 1991) § 12-506 (a), which, in effect, codified the 1989 revision of the statute and Public Act 89-251. The tax benefit rule, as codified at 26 U.S.C. § 111, does not apply to recoveries of depreciation, depletion, amortization or amortizable bond premiums. 26 C.F.R. § 1.111-1 (a).

In his brief, the defendant claims that this court has “repeatedly stated that all exemptions and deductions from taxation are a ‘matter of legislative grace’ and . . . must be strictly construed against the taxpayers and in favor of the taxing authority.” While we take no issue with this general principle, the question of whether the right to an exemption or deduction exists is separate and distinct from the question of what the legislature meant by “ ‘[a]cljusted gross income’ ... as determined for federal income tax purposes.” General Statutes § 12-701 (a) (19). In our view, the proper

interpretation of that phrase does not involve any determination of the existence, or nonexistence, of an exemption or deduction, inasmuch as the proper methodology for determining acljusted gross income predates, in the chronology of our income tax scheme, the question of exemptions or deductions. General Statutes (Rev. to 1993) § 12-701 (a) (20), as amended by Public Acts 1993, No. 93-74, § 39, and Public Acts, Spec. Sess., May, 1994, No. 94-4, § 26, provides: “ ‘Connecticut adjusted gross income’ means adjusted gross income, with the following modifications: (

A) There shall be added thereto (

x) an amount equal to the difference between the amount of Social Security benefits includable for federal income tax purposes under the provisions of

Section 13215 of the Omnibus Budget Reconciliation Act of 1993 and the amount of such Social Security benefits includable for federal income tax purposes under the provisions of the Internal Revenue Code of 1986, or any subsequent corresponding internal revenue code of the United States, as from time to time amended, prior to August 10, 1993. With respect to a person who is the beneficiary of a trust or estate, there shall be added or subtracted, as the case may be, from adjusted gross income such person’s share, as determined under

section 12-714, in the Connecticut fiduciary adjustment.” General Statutes (Rev. to 1973) § 12-505, as amended by Public Acts 1973, No. 73-3-56, § 1, provided in relevant part: “[Taxable gains means] net gains as determined for federal income tax purposes . . . from sales or exchanges of capital assets ... or from transactions or events taxable to the taxpayer such as sales or exchanges . . . under the provisions of the Internal Revenue Code in effect for the taxable year . . . .” For the same reason, the defendant’s reliance on Kellems v. Brown, supra, 163 Conn. 478, also is misplaced.

As with Ruskewich, Kellems did not contain any express limitation on the applicability of federal tax precepts. In support of its contention that § 12-701 (a) (19) does not incorporate the federal tax benefit rule, the dissent relies on the Connecticut Form CT-1040 for the 1994 tax year. Specifically, the dissent notes that line 1 of the form “simply requires the taxpayer to report the line item amount calculated on the federal form,” and from this the dissent infers, based on the legislature’s failure to amend § 12-701 (a) (19) subsequent to the issuance of the form, the legislature’s acquiescence to that

interpretation. It is true that “[t]he legislature is presumed to be aware of the

interpretation of a statute and ... its subsequent nonaction may be understood as a validation of that

interpretation. Martin v. Plainville, 240 Conn. 105, 110, 689 A.2d 1125 (1997).” Commission on Human Rights & Opportunities v. Sullivan Associates, 250 Conn. 763, 783, 739 A.2d 238 (1999). It is also true, as the dissent notes, that we have applied this doctrine of legislative acquiescence to administrative

interpretations of statutes. See id., 782-83; Hansen v. Gordon, 221 Conn. 29, 36, 602 A.2d 560 (1992). The dissent fails to acknowledge, however, that two of the links in the logical chain of the legislative acquiescence doctrine are missing from the facts of the present case. First, the presumption of legislative awareness of prior administrative

interpretations of a statute on which the doctrine is based has, as its factual underpinning, an

interpretation in 1he form of a published administrative opinion or ruling. See, e.g.,Hansen v. Gordon, supra, 221 Conn. 36 (interpretation of statutory definition of “occupational diseases” in Cortes v. Allegheny Ludlum Steel Corp., 1 Conn. Workers’ Comp. Rev. Op. 173, 181-82 [1982]); Connects cut Light & Power Co. v. Public Utilities Control Authority, 176 Conn. 191, 196-97, 405 A.2d 638 (1978) (public utilities control authority decisions concerning electric rates); Housing Authority v. Dorsey, 164 Conn. 247, 253, 320 A.2d 820, cert. denied, 414 U.S. 1043, 94 S. Ct. 548, 38 L.

Ed. 2d 335 (1973) (written opinion of attorney general). We cannot say that a single line on a preprinted tax form should enjoy the same presumption of legislative awareness as those other written and published opinions. We think it unlikely that the legislature either was aware of that line on the form, or that the legislature understood that line as an

interpretation of § 12-701 (a) (19). Second, the legislative acquiescence doctrine requires actual acquiescence on the part of the legislature. In most of our prior cases, we have employed the doctrine not simply because of legislative inaction, but because the legislature affirmatively amended the statute subsequent to a judicial or administrative

interpretation, but chose not to amend the specific provision of the statute at issue. The record in this case is devoid of evidence that the legislature made such a choice with respect to § 12-701 (a) (19). The dissent posits a hypothetical scenario in which a taxpayer, in the same tax year, receives a federal tax benefit due to a loss, but does not receive a Connecticut tax benefit from that same loss. As the hypothetical situation is not raised by the facts of the present case, we leave its resolution for another day.
