- 28 - principle for the period in dispute, the later event is the NOL which arose in 1982, and which was carried back to 1979 which displaced more 1979 credits back to 1977. Section 6601(d)(1) provides specifically: If the amount of any tax * * * is reduced by reason of a carryback of a net operating loss * * * such reduction in tax shall not affect the computation of interest under this section for the period ending with the filing date for the taxable year in which the net operating loss * * * arises. Thus, applying the statute, the interest computation is not changed by the 1982 NOL before March 15, 1983. Before that date, interest is computed on the deficiencies as they existed on January 1, 1980, reflecting the ITC carried back from 1979, as if the NOL had not occurred. Interest should then properly be charged based on the deficiency determined sequentially by succeeding events. That is, as to the 1977 tax year, for the period January 1, 1980, to March 14, 1983, interest is to be computed based on the deficiency amount of $3,777,997, which reflects the carryback from 1979 of an ITC in the amount of $7,947,605 and an FTC in the amount of $2,307,548. As to the 1978 tax year, for the period January 1, 1980, to March 14, 1983, interest is to be computed based on the deficiency amount of $2,530,339, which reflects the carryback from 1979 of an ITC in the amount of $444,727. It should be pointed out that, under this analysis, there is no danger of petitioner's receiving a double benefit for the 1979Page: Previous 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 Next
