LYNCH, J.

The Commissioner of Revenue (commissioner) appeals, pursuant to G.L.c. 58A, § 13, from a decision of the Appellate Tax Board (board) ordering an abatement of a use tax assessed on catalogs that J.C. Penney Company (taxpayer) mailed from out-of-State locations to Massachusetts residents between the years 1991 and 1993. See G.L.c. 64I, § 2. The commissioner argues that the board erred in concluding that the taxpayer's distribution of these catalogs did not constitute a taxable "use" of property, as that term is statutorily defined. G.L.c. 64I, § 1. We transferred the case here on our own motion and now reverse the board's decision.

1. Facts. The taxpayer, a Delaware corporation with its principal place of business in Plano, Texas, is engaged in the business of retail merchandising. During the relevant tax periods, it operated retail stores in all fifty States, including ten stores in Massachusetts, and a direct mail catalog business, which it administered separately from the retail store division.

In connection with its catalog business, each year the taxpayer issued three major seasonal catalogs, as well as various small sale or specialty catalogs, that described and illustrated merchandise available for purchase by mail order. The planning, artwork, design, and layout for these catalogs were completed and paid for outside of Massachusetts, primarily in Texas, and the taxpayer contracted with independent printing companies located outside the Commonwealth to produce the catalogs. During the relevant time period, the three major catalogs were printed in Indiana, while the specialty catalogs were printed in South Carolina and Wisconsin. The taxpayer supplied the printers with paper, shipping wrappers, and address labels for the catalogs; the printers supplied the ink, binding materials, and labor. None of these materials was purchased in Massachusetts.

Printed catalogs, with address labels and postage affixed, were transported by a common carrier from the printer to a United States Postal Service office located outside Massachusetts, where they were sent to Massachusetts addressees via third or fourth class mail. Title to the catalogs passed from the printer to the taxpayer when the common carrier assumed possession. Although the taxpayer made no effort to recall or to change the time or method of delivery of the catalogs after they left the printers' facilities, it instructed the postal service, from its offices outside Massachusetts, to return any undeliverable catalogs to its catalog distribution center in Connecticut.

The catalogs advertised a broader range of merchandise than was available for purchase in the taxpayer's retail stores. The taxpayer's express purpose for mailing these catalogs, free of charge, to residents of, among other places, Massachusetts, was to solicit mail order purchases from current and potential customers. Catalog recipients were selected by the taxpayer at its offices outside Massachusetts. Purchases of catalog merchandise were made by telephoning or returning an order form to the taxpayer at a location outside Massachusetts, and the merchandise was shipped to customers from the taxpayer's Connecticut distribution center.

For each sales and use tax period in the years 1991-1993, the taxpayer filed Massachusetts sales and use tax returns and paid the taxes reflected thereon as due. On August 3, 1993, the commissioner notified the taxpayer that these tax returns had been selected for audit, and on April 26, 1995, assessed the taxpayer for unpaid use taxes, of which $314,674.42, plus interest and penalties, represented a tax on the value of the catalogs the taxpayer mailed to Massachusetts residents during the relevant tax periods. The taxpayer paid the assessment and applied for an abatement. Following the commissioner's denial of this application, the taxpayer appealed to the board. In ordering an abatement of the use tax assessed on the mailed catalogs, the board held that the taxpayer, in causing the catalogs to be mailed from out-of-State locations to Massachusetts residents, had not made a taxable "use" of these items of tangible personal property in Massachusetts, as required by the use tax statute, G.L.c. 64I, § 2.

2. Discussion. Our review of a decision by the board is limited to questions of law, see G.L.c. 58A, § 13; Towle v. Commissioner of Revenue, 397 Mass. 599, 601 (1986), and "encompasses issues of statutory construction." Associated Testing Labs., Inc. v. Commissioner of Revenue, 429 Mass. 628, 631 (1999), citing Tilcon-Warren Quarries Inc. v. Commissioner of Revenue, 392 Mass. 670, 672 (1984). The taxpayer has the burden of proving as a matter of law its right to an abatement of the tax. See Towle v. Commissioner of Revenue, supra at 603. The sole question presented by this appeal is whether the term "use" in G.L.c. 64I, § 2, as defined in G.L.c. 64I, § 1, encompasses a taxpayer's distribution of merchandise catalogs to Massachusetts addressees by means of interstate mail for the purpose of soliciting retail business. We answer this question in the affirmative and, therefore, reverse the board's decision.

General Laws c. 64I, § 2, imposes an excise tax, at the rate of five per cent, on "the storage, use or other consumption in the [C]ommonwealth of tangible personal property or services purchased from any vendor for storage, use, or other consumption within the [C]ommonwealth." "Use" is defined, in relevant part, to "mean and include . . . the exercise of any right or power over tangible personal property incident to the ownership of that property, except that it does not include the sale of that property in the regular course of business." G.L.c. 64I, § 1. Significantly, tangible personal property shipped or brought into Massachusetts by the purchaser within six months after its out-of-State purchase is presumed to have been purchased for storage, use, or other consumption in the Commonwealth. G.L.c. 64I, § 8 ( f). The use tax established by G.L.c. 64I, together with the sales tax in G.L.c. 64H, are complementary elements of a unitary taxing program intended to "reach all transactions, except those expressly exempted, 'in which tangible personal property is sold inside or outside the Commonwealth for storage, use, or other consumption within the Commonwealth.'" M T Charters, Inc. v. Commissioner of Revenue, 404 Mass. 137, 140 (1989), quoting Boston Tow Boat Co. v. State Tax Comm'n, 366 Mass. 474, 477 (1974); Towle v. Commissioner of Revenue, supra at 604. The use tax was thus designed "to prevent the loss of sales tax revenue from out-of-State purchases," M T Charters, Inc. v. Commissioner of Revenue, supra, and to protect local merchants from loss of business to merchants in other States with lower or nonexistent sales taxes. See New York Times Co. v. Commissioner of Revenue, 22 Mass. App. Tax Bd. Rep. 177, 192 (1997), aff'd, 427 Mass. 399 (1998). See also 2 J. W. Hellerstein, State Taxation § 16.03[3] (3d ed. 1998).

In concluding that the taxpayer had not made a taxable "use" of the catalogs mailed to Massachusetts residents, the board reasoned that the taxpayer's activities with respect to the catalogs did not constitute an exercise in the Commonwealth of a right or power incident to the ownership of tangible personal property situated in Massachusetts. G.L.c. 64I, §§ 1, 2. In the board's view, the "exercise" of a right or power over property, such as control, equates with "some degree or form of activity," yet "none of the [taxpayer's] activities undertaken to arrange the in-State distribution of the catalogs occurred in Massachusetts [n]or did [the taxpayer's] relevant activities occur while the catalogs were in the Commonwealth." The board further reasoned that, had the Legislature intended a taxpayer's mailing of catalogs to Massachusetts residents to be subject to the use tax, it would have expressly designated the "distribution" of property as a taxable use in G.L.c. 64I, § 1, as other States have done. Finally, the board interpreted this court's decision in George S. Carrington Co. v. State Tax Comm'n, 375 Mass. 549, 552-553 (1978), to imply that the use tax cannot apply in the circumstances presented by this case, and rejected as unpersuasive numerous decisions from other jurisdictions that have held to the contrary.

In urging us to affirm the board's decision, the taxpayer argues that assessment of a use tax is improper where, as here, the taxpayer "did not do anything with the catalogs in Massachusetts." While this proposition is not objectionable in principle, we reject its application to the undisputed facts of this case. For, contrary to the board's conclusion and the taxpayer's contention, the taxpayer here did, in a very real sense, "do something" with its catalogs in the Commonwealth by distributing them, via the United States Postal Service, to Massachusetts residents, thereby deploying them in the service of its Massachusetts direct mail retail business.

It is a settled principle of our taxation jurisprudence that tax statutes are "to be construed as imposing taxes with respect to matters of substance and not with respect to mere matters of form." Green v. Commissioner of Corps. Taxation, 364 Mass. 389, 394 (1973), quoting Commissioner of Corps. Taxation v. Second Nat'l Bank, 308 Mass. 1, 6 (1941). It is apparent from the board's findings that the taxpayer, even though it did not itself physically possess the catalogs in Massachusetts, nevertheless exercised substantive rights and powers over the catalogs in the Commonwealth by effectuating their delivery to Massachusetts addressees. As the board observed, citing its own precedent, although the acts constituting an exercise of a right or power over property must occur in Massachusetts in order for a taxable "use" to occur, it is not necessary that the taxpayer itself directly perform these acts, but rather this requirement may be satisfied where another possesses and acts on property in the Commonwealth at the taxpayer's direction. See, e.g., New York Times Co. v. Commissioner of Revenue, supra at 189-190, and Federal Express Corp. v. Commissioner of Revenue, 23 Mass. App. Tax Bd. 1, 3-4 (1997), aff'd, 427 Mass. 399 (1998) (taxpayer's directing, through in-State operator, travel of aircraft located in Massachusetts constituted taxable use). This principle is applicable here, as the United States Postal Service, which carried the catalogs into the Commonwealth and delivered them to Massachusetts residents, possessed and acted on the taxpayer's property in the Commonwealth at all times in accordance with the taxpayer's express instructions and on the taxpayer's behalf. The taxpayer, who acquired title to the catalogs prior to their entry into Massachusetts, directed the postal service, and paid it a fee, to deliver the catalogs to specified Massachusetts residents; absent these directions, the catalogs would never have made their way into the Commonwealth or, once here, into the hands of their addressees. Moreover, the taxpayer instructed the postal service regarding the disposition of undelivered catalogs, directing that they be carried out of Massachusetts and returned to its Connecticut distribution center. Pursuant to the board's own prior construction of G.L.c. 64I, § 2, this indirect taxpayer control of the catalogs is indistinguishable, for purposes of determining the applicability of the use tax, from the control the taxpayer would have exercised had it chosen to ship the catalogs into the Commonwealth and to effectuate their delivery by means of a common carrier or its own employees. See New York Times Co. v. Commissioner of Revenue, supra; Federal Express Corp. v. Commissioner of Revenue, supra. Such taxpayer control by proxy over items of tangible personal property sent into Massachusetts via interstate mail thus constitutes an exercise within the Commonwealth of a right or power incident to ownership of that property and, therefore, a "use" of that property within the meaning of G.L.c. 64I, § 2. See, e.g., Service Merchandise Co. v. Arizona Dep't of Revenue, 188 Ariz. 414, 417 (Ct.App. 1996); Sharper Image Corp. v. Miller, 240 Conn. 531, 540 (1997); J.C. Penney Co. v. Balka, 254 Neb. 521, 527 (1998).

Moreover, the economic and commercial reality of the taxpayer's distribution of the catalogs clearly warrants the conclusion that the taxpayer made a taxable "use" of the catalogs in Massachusetts. As the board found, the taxpayer's avowed purpose in mailing the catalogs to Massachusetts addressees was the solicitation of purchase orders from current and prospective customers. By means of the catalogs, then, the taxpayer advertised its merchandise and offered goods for sale in the Commonwealth, and provided Massachusetts residents the means for making purchases (i.e., toll-free telephone number and mail order forms). The catalogs were thus intended to, and did, serve as an instrument in the taxpayer's conduct of a commercial enterprise within the Commonwealth. We conclude that the term "use" in G.L.c. 64I, § 2, encompasses such a commercial utilization of direct mail catalogs and like promotional materials to conduct business in Massachusetts markets, a conclusion that accords with the board's own prior interpretation of the scope of the use tax. New York Times Co. v. Commissioner of Revenue, supra at 191 (powers which owner as well as lessee of tangible personal property may exercise include "the right to employ property in the conduct of a business"). See Jan Co. Cent. v. Commissioner of Revenue, 405 Mass. 686, 689 (1989), citing Prince v. State Tax Comm'n, 366 Mass. 470, 473-474 (1974), and Clark Franklin Press Corp. v. State Tax Comm'n, 364 Mass. 598, 602 (1974) ("certain transfers of tangible personal property . . . are incidental to the transferor's business, serving to facilitate the consummation of the principal transactions" and, therefore, subject to taxation pursuant to G.L.c. 64I, § 2). See also J.C. Penney Co. v. Balka, supra at 527; Comfortably Yours, Inc. v. Director, Div. of Taxation, 12 N.J. Tax 570, 575-577 (1992), aff'd, 272 N.J. Super. 540, 542 (1994); Modern Merchandising, Inc. v. Department of Revenue, 397 N.W.2d 470, 474 (S.D. 1986) (Sabers, J., dissenting); J.C. Penney Co. v. Olsen, 796 S.W.2d 943, 946 (Tenn. 1990).

The absence of the term "distribution" from G.L.c. 64I, §§ 1, 2, does not preclude our construing the term "use" in these statutes to encompass an interstate mailing of promotional materials such as catalogs. Any significance which might be attributed to this absence is outweighed by the Legislature's having defined "use" broadly to "mean and include . . . the exercise of any right or power over tangible personal property incident to the ownership of that property," G.L.c. 64I, § 1, a definition that plainly encompasses a taxpayer's directing another to deliver to intended recipients property to which the taxpayer holds legal title. See Sears, Roebuck Co. vs. State Tax Comm'n, Appellate Tax Bd. No. 64952 (June 27, 1975), rev'd on other grounds, 370 Mass. 127 (1976) ("It is hard to find language broader in sweep and scope than that used [in G.L.c. 64I, § 1,] to express the intent of the [L]egislature"). Moreover, as already noted, we have previously interpreted the use tax as a complement to the sales tax in a unitary taxing program designed "to reach all transactions, except those expressly exempted, 'in which tangible personal property is sold inside or outside the Commonwealth for storage, use or consumption within the Commonwealth.'" M T Charters, Inc. v. Commissioner of Revenue, 404 Mass. 137, 140 (1989), quoting Boston Tow Boat Co. v. State Tax Comm'n, 366 Mass. 474, 477 (1974). See G.L.c. 64I, § 7. Neither the board nor the taxpayer has cited any statutory provision that would exempt from the use tax a taxpayer's distribution by mail in Massachusetts of catalogs it purchased outside the Commonwealth. Cf. Sears, Roebuck Co. v. State Tax Comm'n, supra at 130-131 (distribution of advertising supplements in newspapers, although assumed taxable "use" pursuant to G.L.c. 64I, § 1, held exempt from use tax pursuant to newspaper exemption, G.L.c. 64I, § 7 [ b]). George S. Carrington Co. v. State Tax Comm'n, 375 Mass. 549 (1978), cited by the board, is not to the contrary. That case presented the obverse factual situation from this: the taxpayer, a Massachusetts printer who prepared fund-raising materials on behalf of out-of-State religious charities and mailed those materials to designated prospective donors, most of whom resided outside the Commonwealth, was assessed a sales tax on the mailed materials pursuant to G.L.c. 64H. See id. at 550. The taxpayer argued that the commissioner's imposition of a sales tax on materials mailed out of State was unconstitutional because, among other things, there was a danger that interstate commerce would thus be "smothered by cumulative taxes of several States." Id. at 552-553, quoting Complete Auto Transit, Inc. v. Brady, 330 So.2d 268, 272 (Miss. 1976), aff'd, 430 U.S. 274 (1977). In rejecting this argument, this court reasoned, first, that, because title to the goods passed in Massachusetts and the taxpayer did not have any out-of-State agents to whom it mailed the materials, the taxpayer did not engage in any activity that would support the imposition of a sales tax by another State; and, second, that the risk that the transaction might be subject to a use tax in another State was likewise insubstantial, as most States have enacted statutes that allow taxpayers a credit against assessed use taxes for sales taxes paid to other jurisdictions. See George S. Carrington Co. v. State Tax Comm'n, supra at 553. Thus, nowhere in that case did this court state or imply that no taxable "use" of property can occur where promotional materials produced in one State are mailed to individuals in another State. Indeed, the court's reasoning in that case fairly implies the opposite view, namely, assuming that the constitutional prerequisites for a State's taxation of interstate commerce are satisfied, a use tax may validly be assessed on mailed promotional materials in circumstances such as those present here, subject to a tax credit for sales taxes paid in the State where the taxpayer purchased the materials.

The conclusion we reach today accords with the modern trend among jurisdictions that have addressed this issue. In D.H. Holmes Co. v. McNamara, 486 U.S. 24, 32 (1988), the United States Supreme Court upheld Louisiana's assessment of a use tax on the taxpayer's in-State distribution of catalogs via interstate mail. While we recognize, as did the board below, that the D.H. Holmes Co. case involved a Federal constitutional challenge to a State's authority to tax interstate commerce, we nevertheless consider the Supreme Court's reasoning instructive with respect to the issue of a taxpayer's control of property sent into a taxing State by means of the United States Postal Service. For in concluding that the taxpayer had a substantial nexus with Louisiana that would justify the State's assessment of a use tax on the taxpayer's interstate mailings, the Supreme Court reasoned, in part, that the taxpayer's claim that it lacked control over the catalogs' in-State distribution "verge[d] on the nonsensical," as the taxpayer "ordered and paid for the catalogs and supplied the list of customers to whom the catalogs were sent; any catalogs that could not be delivered were returned to it . . . [and the taxpayer] admit[ted] that it initiated the distribution to improve its sales and name recognition among Louisiana residents. . . . The [taxpayer's] distribution of catalogs to . . . Louisiana customers was directly aimed at expanding and enhancing its Louisiana business." Id. In the wake of the Supreme Court's decision, the overwhelming majority of State appellate courts that have considered the issue have concluded that a taxpayer's distribution of merchandise catalogs and other promotional materials via interstate mail constitutes a taxable "use" of those materials in the destination State. See, e.g., Service Merchandise Co. v. Arizona Dep't of Revenue, 188 Ariz. 414, 417 (1996); Talbots, Inc. v. Schwartzberg, 928 P.2d 822, 823-824 (Colo. Ct. App. 1996); Sharper Image Corp. v. Miller, 240 Conn. 531, 540 (1997); Sharper Image Corp. v. Department of Revenue, 704 So.2d 657, 659-660 (Fla. Dist. Ct. App. 1997), cert. denied, 526 U.S. 1016 (1999); Collins v. J.C. Penney Co., 218 Ga. App. 405, 407-410 (1995); American Express Travel Related Servs. Co. v. Tax Comm'n, 128 Idaho 902, 903-905 (1996); J.C. Penney Co. v. Balka, 254 Neb. 521, 527 (1998); J.C. Penney Co. v. Olsen, 796 S.W.2d 943, 945 (Tenn. 1990). See also Sharper Image Corp. v. Comptroller of the Treasury, Md. Tax Ct. No. 582 (Feb. 18, 1993); Comfortably Yours, Inc. v. Director, Div. of Taxation, 12 N.J. Tax 570, 574-578 (1992).,

Finally, as we have already observed, the underlying policy of G.L.c. 64I, § 2, supports the assessment of a use tax on property purchased outside Massachusetts for, inter alia, "use" within the Commonwealth in order both to prevent the loss of sales tax revenue to neighboring States and to ensure that Massachusetts businesses may compete on an even footing with their counterparts in other States with lower or nonexistent sales taxes. To hold the use tax inapplicable to the circumstances of this case would frustrate each of these policy goals by allowing a merchant operating in Massachusetts to avoid taxes altogether on promotional materials it uses to generate retail business in the Commonwealth merely by arranging to have these materials produced in, and mailed to prospective Massachusetts customers from, other States that impose no sales tax on the purchase of these materials. Such an outcome, by encouraging Massachusetts merchants to have their promotional mailings produced out-of-State, would clearly result in a loss of sales tax revenue for the Commonwealth, and would put Massachusetts companies that produce such promotional materials under a competitive disadvantage relative to producers in those other States. Moreover, there is no danger that merchants subject to a Massachusetts use tax on their interstate promotional mailings will suffer from an excessive, cumulative tax burden, as the Legislature has provided a credit against assessed use taxes for any sales taxes paid to other jurisdictions that offer a similar credit for sales taxes paid to the Commonwealth. See G.L.c. 64I, § 7 ( c).

In sum, the assessment of a use tax on catalogs and other promotional materials that a Massachusetts merchant sends to residents of the Commonwealth by interstate mail is consistent both with the plain language of G.L.c. 64I, § 2, and its underlying policy. Accordingly, the taxpayer has not met its burden of proving that it is entitled to an abatement of the use tax assessed on its direct mail catalogs.

Decision of the Appellate Tax Board reversed.
