RAUM, Judge:
Respondent has determined deficiencies in the income tax of petitioners' decedent as follows:
Year Amount
1950 .............................................. $694.00 1951 .............................................. 735.56 1952 .............................................. 566.79
The sole issue is whether respondent erred in refusing to include payments on account of deficiencies in income taxes of prior years in determining whether payments on account of estimated tax in each of the taxable years in question equaled at least 80 per cent of the total tax liability for each such year. All of the facts have been stipulated.
Arthur Garfield Hays was an individual residing at 24 East 10th Street, New York City. His individual income tax returns for the calendar years 1950, 1951, and 1952 were filed with the then collector of internal revenue for the second district of New York at New York City. He died on December 14, 1954. William Abramson and Lawrence Fertig are the duly appointed executors of his will.
At all times material decedent was a partner in a law firm. In each of the years 1948 to 1952, inclusive, his net income and income tax payable, as determined by respondent, were as follows: Income Year Net income tax payable 1948 ...................................... $59,065.73 $28,271.63 1949 ...................................... 54,152.37 25,134.17 1950 ...................................... 43,556.18 19,066.72 1951 ...................................... 44,993.13 22,259.26 1952 ...................................... 53,052.75 29,046.51 As of January 1, 1950, decedent was indebted to the United States for income taxes for prior years as follows:
Calendar Year Amount
1946 .......................................... $2,094.69 1947 .......................................... 2,025.54 1948 .......................................... 2,507.41 1949 .......................................... 14,527.70
Decedent's income tax liability for 1950, 1951, and 1952 as finally determined, and 80 per cent thereof, are as follows: 80 per cent Year Liability of liability 1950 .................................... $19,066.72 $15,253.38 1951 .................................... 22,259.26 17,807.41 1952 .................................... 29,046.51 23,237.21 Decedent made the following payments on account of various income tax liabilities as follows: Date of payment Amount Purpose of payment Jan. 16, 1950 ................ $2,500.00 1949 estimated tax Mar. 10, 1950 ................ 2,500.00 1949 income tax Mar. 10, 1950 ................ 2,500.00 1950 estimated tax June 14, 1950 ................ 2,500.00 1950 estimated tax July 6, 1950 ................. 2,500.00 1949 income tax July 11, 1950 ................ 2,094.69 1946 income tax deficiency 34.17 Interest thereon Sept. 15, 1950 ............... 2,500.00 1950 estimated tax Oct. 20, 1950 ................ 1,000.00 1949 income tax Nov. 22, 1950 ................ 4,500.00 1949 income tax Feb. 1, 1951 ................. 500.00 On account 1949 Feb. 20, 1951 ................ 804.41 1947 add. and interest Feb. 20, 1951 ................ 3,106.47 1949 add.

However, in no case did the total amount of payments on account of estimated tax alone for a current year equal as much as 80 per cent of such liability.
Petitioners contend that in determining for the purposes of section 294 (d) (2) of the Internal Revenue Code of 1939 whether 80 per cent of total tax liability for a given year was paid on account of estimated tax, we should include payments made not for that purpose, but to satisfy liabilities resulting from arrears in income taxes due in respect of prior years. This we cannot do.

(d) ESTIMATED TAX. —

(2) SUBSTANTIAL UNDERESTIMATE OF ESTIMATED TAX. — If 80 per centum of the tax * * * exceeds the estimated tax * * * there shall be added to the tax an amount equal to such excess, or equal to 6 per centum of the amount by which such tax so determined exceeds the estimated tax so increased, whichever is the lesser.

The duty to pay income taxes still due for any prior year is a complete obligation in itself, entirely separate and distinct from the duty to make payments on account of estimated tax liability for the current year. A payment in satisfaction of one liability cannot be deemed at the same time to satisfy the other. When decedent paid amounts on deficiencies due in respect of prior years, he received everything to which he was thereby entitled when such amounts were so credited as to reduce his liability in respect of those deficiencies. Petitioners, however, would have such payment serve not only that purpose, but also constitute a payment of amounts currently due in respect of estimated tax. No authority is cited to support this novel doctrine, and we know of none.
Were the payments in question in satisfaction of gift tax or excise tax liability, or some non-tax-created liability to the United States, we doubt that petitioners would urge the result they seek here. We do not deem it a distinction that those payments happen instead to be applicable to an income tax liability for a different year.
It is unclear whether and to what extent petitioners are suggesting reasonable cause as a defense. In any event, reasonable cause is irrelevant here. H. R. Smith, 20 T.C. 663.
Nor can the cause of petitioners be aided by section 6654 of the Internal Revenue Code of 1954. Even assuming that that provision would require a different result in later taxable years under the same set of facts and circumstances (and we express no opinion on that point), the instant proceeding is not governed thereby. Section 6654 is not retroactive in its effect, and it is clearly amendatory, not declaratory of prior law.
Respondent's determination must be sustained.
Decisions will be entered for the respondent.
