The facts in this proceeding are not disputed. Petitioner seeks a review of a determination of the State Tax Commission, denying petitioner’s refund claim of mortgage taxes in the sum of $5,375, and affirming the action of the Register of the City of New York in collecting such tax upon the recording of a certain instrument, hereinafter described as a “ Third Supplemental Indenture ”. The tax was paid under protest.
On July 15, 1935, the Park and 46th Street Corporation executed a mortgage to Chase National Bank of the City of New York, trustee, in the sum of $1,800,000 and paid a mortgage tax of $9,000 upon recording on August 22, 1935. This mortgage pledged a leasehold which expired October 1,1947, with privilege to renew to April 1, 1965, and provided for the issuance of and securing of 5% bonds aggregating $1,800,000, the bonds to be issued in twenty-four series of $75,000' each with consecutive maturity dates July 15th and January 15th up to and including July 15, 1947. The mortgage contains no provision for issuance of refunding bonds and no covenant providing for refinancing.
On .December 15, 1939, a supplemental instrument between the parties was recorded providing for the issuance of additional bonds in the aggregate amount of $300,000, bearing interest at the rate of 4%, to be issued in fifteen series of $20,000 each, to mature January 15th and July 15th, consecutively up to July 15,1947. A recording tax of $1,500 was paid upon the recording of the instrument.
*9An instrument entitled “ Second Supplemental Indenture ”, dated July 15, 1941, and recorded December 12, 1941, provided for the issuance of $420,000 of 5% bonds all maturing July 15, 1947, in partial replacement of previously issued bonds. The register granted tax exemption on-this instrument.
The instrument involved here entitled “ Third Supplemental Indenture ”, dated November 15, 1943, was recorded November 30,1943. This recites the making of the 1935 mortgage and the 1939 and 1941 indentures and the issuance of the bonds aggregating $1,800,000, $300,000 and $420,000, respectively, thereunder; and that there are outstanding 5% bonds and 4% bonds aggregating $1,075,000. It provides for a new series of 4%% bonds aggregating $1,200,000 in forty series of $30,000 each, to be lettered A through Z and AA through NN, with series A to mature May 15, 1944, and bonds of consecutively lettered series to mature each November 15th and May 15th thereafter, to and including November 15, 1963. The leasehold estate expiring April 1, 1965, is pledged and the new bonds are stated to be issued under and secured by the 1935 mortgage and the 1939, 1941 and 1943 indentures. A portion of these bonds aggregating $1,075,000 are to be delivered “ only to the registered holder of all of the Old Serial Bonds upon surrender to the Trustee by said registered holder of all the Old Serial Bonds for cancellation.” The petitioner herein requested that an exemption be granted from the recording tax as to this $1,075,000 of indebtedness evidenced by these bonds and secured under the indenture. This exemption was denied.
Petitioner claims exemption solely under section 255 of the Tax Law. A mortgage is defined as an instrument which ‘ ‘ imposes a lien on or affects the title to real property, notwithstanding that such property may form a part of the security for the debt or debts secured thereby.” (Tax Law, § 250.) By the provisions of section 253 of the Tax Law such an instrument is subject to a recording tax. The tax is imposed not upon the debt itself but upon the written evidence of collateral security required to be recorded. The debt is merely the .basis for computation of the tax. (People ex rel. N. Y. T. & M. Co. v. State Tax Comm., 220 App. Div. 396, affd. 245 N. Y. 603; People ex rel. Metro. Playhouses, Inc., v. Graves, 251 App. Div. 655, affd. 275 N. Y. 621.)
Section 255 of the Tax Law under which petitioner claims exemption provides: “ If subsequent to the recording of a mortgage on which all taxes, if any, accrued under this article have been paid, a supplemental instrument or mortgage is recorded *10for the purpose of correcting or perfecting any recorded mortgage, or pursuant to some provision or covenant therein, or an additional mortgage is recorded imposing the lien thereof upon property not originally covered by or not described in such recorded primary mortgage for the purpose of securing the principal indebtedness which is or under any contingency may be secured by such recorded primary mortgage, such additional instrument or mortgage shall not be subject to taxation under this article, unless it creates or secures a new or further indebtedness or obligation other than the principal indebtedness or obligation secured by or which under any contingency may be secured by the recorded primary mortgage, in which case, a tax is imposed as provided by section two hundred and fifty-three of this chapter on such new or further indebtedness or obligation, and shall be paid to the proper recording officer at the time such instrument or additional mortgage is recorded. If at the time of recording such instrument, or additional mortgage any exemption is claimed under this section, there shall be filed with the recording officer and preserved in his office a statement under oath of the facts on which such claim for exemption is based. The determination of the recording officer upon the question of exemption shall be reviewable by the tax commission.”
To be entitled to an exemption under this section the supplemental mortgage must be recorded: (1) For the purpose of correcting or perfecting a prior recorded mortgage; (2) Pursuant to some provision or covenant in a prior recorded mortgage; (3) For the purpose of imposing the lien of a prior recorded mortgage upon property not originally covered by or not described in such prior recorded mortgage as additional security thereunder.
There is no claim here that the instrument of November 15, 1943, was recorded for the purpose of correcting or perfecting a prior recorded mortgage, nor was it offered for record for the purpose of imposing a lien upon property not originally covered by or not described in a prior recorded mortgage as additional security thereunder.
• The petitioner contends that the supplemental indenture of November 15, 1943, falls within the purview of section 255 because it is offered for record pursuant to some provision or covenant contained in the original mortgage. There is no cove: nant or provision in the mortgage under which the mortgagor or mortgagee would be obliged to give or accept a new mortgage if requested. In People ex rel. U. S. Title G. Co. v. State *11Tax Comm. (230 N. Y. 102, at p. 105) the court said: “We think that none of these exceptions is applicable here. The mortgage now in controversy is not a supplemental one at all. It does not correct or perfect any error or omission. It is not made ‘ pursuant to some provision or covenant ’ contained in an existing mortgage, i.e., in fulfillment of some obligation to give or to accept it. The statement that the mortgagee shall have the option to accept another and larger mortgage at the mortgagor’s request is not a covenant at all. It is not a ‘ provision ’ imposing some obligation ‘ pursuant to ’ which anything has been or could be done. It is merely an assertion that the parties have capacity to make another contract if they please. In this respect the case is unlike People ex rel. Home Mortgage Investment Co. v. State Board of Tax Commissioners (182 App. Div. 699), relied on by the Appellate Division. There the mortgagor was not merely privileged, but required, to make a new mortgage if requested. Finally, the mortgage before us is not a supple- - mental instrument imposing a lien upon property ‘ not originally covered by or described in ’ the mortgage first recorded.”
An examination of the indenture in question shows that it is in all respects a complete mortgage in which the leasehold estate is described in full, in which the form of the bonds to be issued is completely set forth and in which the petitioner, Park and 46th Street Corporation, pledges its property to secure indebtedness not to exceed at any one time $1,200,000. It therefore falls within the definition of a mortgage as set forth in section 250 of the Tax Law.
In our opinion the decision in People ex rel. Jewelers B. Corp. v. State Tax Comm. (214 App. Div. 99, affd. 241 N. Y. 524) is controlling here. In that case the taxation of a consolidation agreement securing a bond for $1,000,000 was sustained. The agreement recited that it consolidated a mortgage in the amount of $750,000 executed by the same mortgagor with another mortgage of $250,000, both of which mortgages were and continued to be unsatisfied of record. It provided for the elimination of the bond secured by the earlier mortgages and the making of a new bond by the same mortgagor in the amount of $1,000,000, to be secured by the new instrument. The court held that the so-called consolidation agreement was a mortgage within the meaning of the mortgage tax article of the Tax Law. Petitioner asserts that the prior mortgages in that case, unlike the mortgages in the instant case, were discharged. However, an examination of the original record discloses an affidavit by the attorney for the Jewelers Building Corporation, Schedule 10 *12attached to the original petition, which reads as follows: ‘ ‘ The affidavits show that the arrangement herein applied was as to form only, that no new loan was made to the mortgagor; that the $750,000 mortgage and the $250,000 mortgage were not satisfied, are still open on record and are merged into the $1,000,000 mortgage or consolidation agreement as by reference therein disclosed. ’ ’
The petitioner occupies no different position in the case at bar with respect to the payment of the tax on the $1,075,000 from that of the petitioners in the Jewelers Building case where a tax was assessed against a mortgage of $750,000 although a tax had' previously been paid when the mortgage was originally recorded. The consolidation agreement which included a new mortgage and the old mortgage of $750,000 was held not to be supplemental within the meaning of section 255 of the Tax Law.
The decisions in Matter of Gramott Corp. v. Graves (255 App. Div. 255, affd. 280 N. Y. 588) and People ex rel. West-brook-Buffalo v. State Tax Comm. (257 App. Div. 705, affd. 283 N. Y. 552) involved application for refunds made on mortgages which after the passage of the amendment to section 252 would have been tax free. The courts in both cases considered first whether the mortgage was exempt under the provisions of section 255 since obviously they did not fall within the exemption granted by the Legislature in amending Tax Law, section 252. In both cases the tax was upheld and the claim that the mortgages were not taxable under section 255 was denied.
In People ex rel. Banner L. Co. v. State Tax Comm. (244 N. Y. 159), cited by the petitioner, it was held that the mortgages fell within the terms of the exceptions in section 255 because they were executed for the purpose of perfecting the original mortgage.
The petitioner places its main reliance upon the cases of People ex rel. B. & M. R. R. v. Loughman (227 App. Div. 361, affd. 254 N. Y. 513) and Matter of New York-State Gas & El. Corp. v. Gilchrist (209 App. Div. 771, affd. on opinion below 240 N. Y. 552). These cases are not in point having been decided under the provisions of section 259 of the Tax Law.
It should be noted that in neither the Boston & Maine nor New York State Gas & Electric cases cited by the petitioner was there1 a supplemental mortgage under consideration. Those decisions accordingly are not authority on the present, issue.
Since the supplemental indenture herein is to all intents and purposes a new mortgage and does not fall within the exemptions *13set forth in. section 255 of the Tax Law, we submit that it is subject to the full amount of the tax.
The determination of the State Tax Commission should be confirmed, with fifty dollars costs and disbursements.
