When the first Georgia income tax act was enacted in 1931 (Ga. L. 1931, Ex. Sess., p. 41) it was provided in Code § 92-3120 (d): “The distribution to the taxpayer of the assets of a corporation shall be treated as a sale of the stock or securities of the corporation owned by him, and the gain or loss shall be computed accordingly.” This left no doubt but that, when a corporation was dissolved, its assets, including accumulated earned surplus retained over the life of the corporation, which was exchanged for stock on dissolution constituted a sale and not a dividend. However the act of 1937 (Ga. L. 1937, pp. 109, 112) added a definition of the word “dividend” in Code § 92-3002 (o) which included the following sentence: “It includes such portion of the assets of a corporation distributed at the time of dissolution as would in effect be a distribution of earnings.” It is now contended by the Revenue Commission that the entire earned surplus is not “assets . . . treated as a sale of the stock” but is “in effect a distribution of earnings.” If correct, such interpretation effects a repeal by implication of so much of Code § 92-3120 (d) as allows all assets, including those representing accumulated earned surplus, to be *765treated as a sale. It accordingly becomes necessary to ascertain the intention of the legislature in enacting the amendment in view of the facts existing at that time.
Four factors suggest themselves as bearing on this problem. First, the question was not a novel one for it had been giving trouble to the Federal Government in respect to returns under the Federal income tax act upon which much of our income tax law is patterned. Between 1913 and 1936 the law as to liquidating dividends had been changed six times, and in 1936 the provisions of the 1934 statute requiring liquidating dividends to be treated as ordinary income were dropped and Congress went back to the 1924 method of treating them as capital gains. See Lynch v. Hornby, 247 U. S. 339 (38 S. Ct. 543, 62 L. Ed. 1149); 38 Stat. 167; 39 Stat. 756, 757; 40 Stat. 329, 337; 40 Stat. 1058, 1059; 42 Stat. 227, 228; 43 Stat. 254, 255; 48 Stat. 683, 711; 49 Stat. 1648, 1687; 47 Yale Law Journal 1146. Section 115 (g) (1) of the Federal Revenue Code in' effect in 1937 (Cf. Revenue Code of 1954, 26 U. S. C. A. §§ 302, 331) provided as follows: “If a corporation cancels or redeems its stock (whether or not such stock was issued as a stock dividend) at such time and in such manner as to make the distribution and cancellation or redemption in whole or in part essentially equivalent to the distribution of a taxable dividend, the amount so distributed in redemption or cancellation of the stock, to the extent that it represents a distribution of earnings or profits accumulated after Fébruary 28, 1913, shall be treated as a taxable dividend.” The applicable U. S. Treasury Department regulation thereunder (Reg. 94, Art. 115-9) which has the force and effect of law (Stegall v. Thurman, 175 F. 813) provides as follows: “A bona fide distribution in complete cancellation or redemption of all of the stock of a corporation, or one of a series of bona fide distributions in complete cancellation or redemption of all of the stock of a corporation, is not essentially equivalent to the distribution of a taxable dividend.” No question has ever arisen but that this statute allowed capital gains treatment of earned surplus on the bona fide dissolution of a corporation. Corporate Liquidations and the Federal Income Tax, University of Penn. Law Review, Vol. 89, p. 907. So it *766can at least be assumed that, even though at the time of passage of our 1937 amendment to the State income-tax law there was no capital gains deduction (this was added by Ga. L. 1952, p. 405) and accordingly no tax advantage either way in treating the earned surplus as a sale or an ordinary taxable dividend, the legislature was aware of the distinction between the two methods of treatment.
Second, being aware of such difference, had the legislature desired to change the existing State law on the subject it appears that it would have done so directly. The 1937 amendment is a rather complete overhaul of the 1931 act. It was not merely an addition to the original act; the legislature adopted the pattern of amending each Code section separately. Twenty-four Code sections were so amended or rewritten, 10 of which are to be found in Chapter 92-31. Yet Code § 92-3120 was not changed in any respect although this is the only Code section dealing with treatment of the assets of the corporation on dissolution, which offers some intrinsic evidence that the legislature did not intend to alter this method of dealing with assets.
Third, this is all the more true because the original provisions of Code § 92-3120 (5) provide for treating certain distributions as taxable dividends where a corporate reorganization, rather than a corporate dissolution, is effected.
Fourth, subsequent treatment of the same subject matter by the legislature may shed some light on the question of the original intent. Patten v. Miller, 190 Ga. 152 (8 S. E. 2d 786). Code § 92-3120 was amended in 1956 (Ga. L. 1956, pp. 608, 609) by the addition of subdivision (h) providing, in case of a distribution in complete liquidation of a corporation in the circumstances outlined in 26 U. S. C. A. § 333 (Internal Revenue Code of 1954) that gain shall be recognized as therein provided. Section 333 provides a method by which, if the taxpayer elects, he may, by reporting that portion of the accumulated earned surplus received in the distribution as a dividend, acquire an unrecognized capital gain on that portion of the capital gain not represented by money or negotiable securities and defer tax payment on the latter assets until they are liquidated. • This part of the Federal act has been incorporated in our State law by reference, *767and under it the taxpayer must make written election to receive dividend treatment of the accumulated surplus on dissolution in order to defer the capital gains tax on a portion of the other assets. That part of the Federal law, adopted by Code § 92-3120 (h) at least, would be inapplicable if under State law the taxpayer were given dividend treatment of the accumulated earned surplus in any event, and the general legislative scheme of conforming the State and Federal income-tax plans as relating to corporate dissolutions, as well as the practical efficiency resulting from such conformation, readily appears.
There is accordingly valid room for doubt as to whether the legislature intended by the last sentence of Code § 92-3002 (o) to change the plain and unambiguous wording of Code § 92-3120 (d) without reference to the latter section, and it becomes proper to consider whether a meaning may be given to the amendment which will harmonize it with the earlier act instead of effecting a partial repeal by implication, since the intention of the legislature to amend an existing law by implication “must be clearly and unquestionably shown by the provisions of the amending act.” Brinkley v. Dixie Construction Co., 205 Ga. 415 (54 S. E. 2d 267). In such a situation “the contemporaneous practical construction of ambiguous or doubtful provisions of an act by the department of the State empowered with its administration or supervision will be given great weight, and will not be disturbed except for weighty reasons.” State of Georgia v. Camp, 189 Ga. 209 (1) (6 S. E. 2d 299). “‘Contemporaneous construction’ within the meaning of the rule, is the construction which executive departments or officers charged with the enforcement of the statute give to it at or near the time of its enactment.” 82 C. J. S. 768, Statutes, § 359.
It appears from this record that one of the regulations of the State Revenue Commissioner interpreting Code § 92-3119 (d) (Ga. L. 1952, p. 405 et seq.) relating to computation of capital gain from the sale or exchange of capital assets is as follows: “The act was designed to closely follow the provisions in Federal law pertaining to capital gains and losses, and for this reason, the State Revenue Commissioner adopts, for all practical purposes the Federal regulations relating to the subject, except *768in those cases where the laws conflict.” The laws did not conflict on this issue in the estimation of the Revenue Commissioner prior to the instigation of this case, as shown by the fact that the Revenue Commissioner had adopted a regulation interpreting Code § 92-3002 (o) which was the exact language of § 115 (g) (1) of the Federal Internal Revenue Code, supra, as follows: “If a corporation cancels or redeems its stock (whether or not such stock was issued as a stock dividend) at such time and in such manner as to make the distribution and cancellation or redemption in whole or in part essentially equivalent to the distribution of a taxable dividend, the amount so distributed in redemption or cancellation of the stock, to the extent that it represents a distribution of accumulated earnings or profits, shall be treated as a taxable dividend.” We have already shown that no question has ever been raised over the meaning of the Federal statute; it allows capital gains treatment of liquidating dividends on dissolution and has always been so understood and applied. The State regulation further provides: “Any distribution made to a shareholder, except in liquidation, is to be treated as ordinary gain regardless of the source of the profits which are distributed.” (Emphasis added). There is accordingly no doubt but that the contemporaneous interpretation given the act by the Revenue Commissioner was to treat a distribution of assets to the stockholders upon dissolution in the same manner that such distribution was treated under the Federal law*. Both sides to this controversy agree that under Federal law such assets are entitled to capital gains treatment where there is a bona fide dissolution of the corporation; they become subject to dividend treatment so as to be taxed as ordinary income only in those situations where the liquidation is not a bona fide dissolution but is a scheme or device to effect a distribution which is in effect a taxable dividend through a change in the form but not the substance of a corporate business activity. See also Harvard Law Review, Yol. 55, p. 835 et seq.
The Revenue Commission now wishes this court to take a contrary position from that which it has adopted in its own regulations. The new position now offers a tax advantage to the State, but the original position was adopted at a time when *769there was no difference in State law, taxwise, whether liquidating dividends were considered as ordinary dividends or as capital assets. The original position of the Revenue Commission as shown by its regulations adopted in the language of the Federal statute contravenes no rule of law. It has the advantage of avoiding a repeal by implication of a prior existing unambiguous statute by virtue of an amendment where the circumstances surrounding the amending act show no indication on the part of the legislature to effect such a repeal. It distinguishes between bona fide and mala fide transactions in a manner which is both fair and in accordance with similar provisions in the Federal act. We accordingly construe the words of Code § 92-3002 (o) “such portion of the assets . . . distributed . . . as would in effect be a distribution of earnings” to mean such portion of the assets as would be “essentially equivalent to the distribution of a taxable dividend” under 26 U. S. C. A. § 115 (g) and the regulations of the Revenue Commissioner interpreting the Code section.
In the present instance it is stipulated that the distribution was made in a bona fide dissolution of the corporate business. Therefore, if the meaning of the Federal act incorporated in the State regulation applies, the tax should be computed on a capital gains basis, which is what the taxpayer did. We hold this to be the proper construction of the law. It was accordingly error for the judge of the superior court to sustain the deficit assessment of the Revenue Commissioner.
In reaching this conclusion we have not ignored Reeves v. Turner, 289 Ky. 426 (158 S. W. 2d 978), and Collins v. Kentucky Tax Commission (Ky.) 261 S. W. 2d 303. Those cases are authority for the proposition that the provisions of our Code § 92-3002 (o) above quoted, standing alone, mean that accumulated earnings exchanged for stock on liquidation are to be taxed as income to the taxpayer, since the Kentucky statute included in its definition of dividend “such portion of the assets of a corporation distributed at the time of dissolution as is in effect a distribution of earnings or profits.” The Kentucky statute was broader, of course (it has since been repealed) since it also included profits of the corporation, but the Kentucky statute had *770no provision similar to our Code § 92-3120 (d) which provides that distribution to the taxpayer of the assets shall be treated as a sale of stock. As pointed out in the Reeves case, the Kentucky provision for excluding, for purposes of ascertaining income, sales of capital assets held for more than two years refers to the imposition of tax on the corporation, not on the shareholder. Accordingly, a very different situation was presented to the Kentucky courts from that here involved.
