Petitioner seeks review1 of a decision of the Board of Tax Appeals for the District of Columbia concerning personal property and business privilege taxes for the fiscal years ending on June 30 in 1938 and 1939. Petitioner, a Maryland corporation, operates department stores in New York, Baltimore and Washington, and smaller stores elsewhere, each as a largely independent unit. The taxes were assessed in respect of the Washington store.
Petitioner filed personal property tax returns and paid corresponding assessments. Afterwards, in 1939, the assessor audited petitioner’s returns. He then found that petitioner had failed to follow the regulations in valuing its inventories and accounts receivable, and had failed to make a full return of cash. He revalued petitioner’s assets, and made additional assessments which were paid under protest. Petitioner applied to the Board of Tax Appeals for refund. It contended that the reassessments were unauthorized and erroneous; and, in the alternative, that its increased payments of tangible personal property taxes “should be allowed as credits against the business privilege tax” which petitioner had paid. Respondent contended that the reassessments should be further increased. The Board of Tax Appeals overruled petitioner’s contentions and sustained respondent’s.
Inventory. Regulations reflected in the official forms of return provided: “Average inventory means net cost of the goods delivered or the actual cost of the goods minus any cash discounts from which a further deduction of 5% will be allowed.” It is not shown, or in terms contended, that cost is an unreasonable basis for determining the value of inventory for the purposes of this tax. Petitioner contends that since it estifnated its “cost” according to the “retail inventory method of accounting”, by deducting from resale price the average percentage of “mark-up” over cost, it is •entitled to deduct an additional 8% for “mark-down.” No mark-down from resale price can affect cost. Moreover, the Board found that petitioner’s mark-down represented the “average percentage reduction of merchandise below its ordinary or usual selling price” for miscellaneous reasons, including obsolescence, attracting customers, and advertising. Even if value were to be determined independently of cost, it would not be affected by a mark-down for advertising purposes. Since it does not appear how much of the mark-down was for such purposes, this is enough to defeat petitioner’s claim.
Accounts receivable. Regulations and instructions in force when the returns were filed provided: “Accounts receivable on 30, 60 or 90 day accounts should be reported in the gross amounts less 5% deduction. Accounts receivable beyond 90 days should be reported in the gross amount less 10% deduction.” When the assessor audited the return he discovered that petitioner had not followed these regulations. He thereupon reassessed its accounts receivable. In doing so he purported to apply new regulations, then in force, which permitted deductions of 10% on regular trade accounts and 25% on installment accounts. The Board of Tax Appeals vacated this reassessment, and made one substantially in accordance with the regulations in force when the returns were filed.2 Petitioner contends that it should have the benefit of the new regulations, since it was the assessor’s practice to apply them retrospectively when unreported instalment accounts were discovered on audit. But that practice rewards the making of incorrect returns, and is unauthorized.
The Board, though it allowed a deduction of 10% on petitioner’s receivables, found that a fair valuation would be their face amount less 5%. Respondent contends that this finding is supported by schedules taken from petitioner’s federal income tax returns for the fiscal years ending January 31, 1931 through January 31, 1940. These schedules list the totals of certain types of credit sales, and the losses on them. Credit sales during a year and accounts receivable on a tax day necessarily differ. Since the schedules relate to sales, the ratio derived from them cannot be applied to receivables. But the record does not support petitioner’s contention that it is entitled to an allowance of more than 10%. Its figures concerning experience with wearing-apparel accounts are not a sufficient sample of its *355credit accounts, and are not sufficiently authenticated and explained. Its credit and collection costs are not material here. Such costs no more reduce the value of credit accounts than salesmen’s wages reduce the value of inventories.
Cash. The personal property tax law provided: “The moneys and credits, including moneys loaned and invested, bonds and shares of stock * * * of any person, firm, association, or corporation resident or engaged in business within said District shall be scheduled and appraised * * * and assessed at their fair cash value * * *.”3 Petitioner reported only cash on hand and in banks in the District of Columbia on the tax dates. It constantly shifted cash between Washington, Maryland and New York, as the needs of its stores required. The Board found that all its cash was available for use by its Washington store, and assessed against petitioner a percentage of its cash, wherever deposited, fixed by the ratio of Washington sales and profits to total sales and profits. We think the Board was right. In Maryland & Virginia Milk Producers’ Ass’n v. District of Columbia4 we held, on the authority of Wheeling Steel Corporation v. Fox,5 that a Maryland corporation which did business and had a “commercial domicile” here was taxable on securities kept in Virginia but used in the business which it conducted here. The policies of petitioner’s Washington store were determined in Washington. The fact that the employees of this store could not draw on funds until they were transferred to Washington banks is immaterial. Funds were freely transferred. Considerably more cash was necessary for the operation of the. local store, and was usually deposited in local banks, than was on deposit here on the tax days. The amount, whether great or small, deposited here on those particular days would be a comparatively arbitrary measure of the amount held and used for the purposes of the local business.
Reassessment. Petitioner attacks all reassessments, as such, and cites Hunt v. District of Columbia.6 That case is not in point, since Hunt made a full return and valued his assets “in accordance with the instructions printed on the official blank.”7 Moreover, an amendment to the District of Columbia Revenue Act approved May 16, 1938, provides: “In the case of a false or incorrect return, whether in good faith or otherwise * * * or of a failure to include taxable property or assets belonging to the taxpayer in any return filed by such taxpayer, whether in good faith or otherwise, the tax may be assessed at any time * * *.”8
Petitioner’s claim that the business privilege taxes which it had previously paid should be abated to the extent of its additional payments of tangible personal property taxes is barred, since petitioner’s appeal to the Board was made more than 90 days after notice of assessment of the business privilege taxes.9 The statute contemplated abatement only in respect of such property taxes as were promptly paid.10 Bull v. United States,11 on which petitioner relies, turned on the fact that a tax had been innocently overpaid, through a mistake of the government, and its retention would therefore have been unjust. Here the government made no mistake. Petitioner overpaid its business privilege taxes only because, on its own responsibility, it made incorrect returns and underpaid its personal property taxes.
Affirmed.
