In addition, there shall be allowed as a deduction under this section State and local and foreign taxes not described in subparagraphs (1) through (5) of this paragraph which are paid or accrued within the taxable year in carrying on a trade or business or an activity described in section 212 (relating to expenses for production of income). For example, dealers or investors in securities and dealers or investors in real estate may deduct State stock transfer and real estate transfer taxes, respectively, under section 164, to the extent they are expenses incurred in carrying on a trade or business or an activity for the production of income. In general, taxes are deductible only by the person upon whom they are imposed. However, see § 1.164-5 in the case of certain taxes paid by the consumer. Also, in the case of a qualified State individual income tax (as defined in section 6362 and the regulations thereunder) which is determined by reference to a percentage of the Federal income tax (pursuant to section 6362 (c)), an accrual method taxpayer shall use the cash receipts and disbursements method to compute the amount of his deduction therefor. Thus, the deduction under section 164 is in the amount actually paid with respect to the qualified tax, rather than the amount accrued with respect thereto, during the taxable year even though the taxpayer uses the accrual method of accounting for other purposes. In addition, see paragraph (f)(1) of § 301.6361-1 of this chapter (Regulations on Procedure and Administration) with respect to rules relating to allocation and reallocation of amounts collected on account of the Federal income tax and qualified taxes.
