§ 1.481-2. Limitation on tax.

An unmarried individual taxpayer using the cash receipts and disbursements method of accounting for the calendar year is required by the Commissioner to change to an accrual method effective with the year 1958. As of January 1, 1958, he had an opening inventory of $11,000. On December 31, 1958, he had a closing inventory of $12,500. Merchandise purchases during the year amounted to $22,500, and net sales were $32,000. Total deductible business expenses were $5,000. There were no receivables or payables at January 1, 1958. The computation of taxable income for 1958, assuming no other adjustments, using the new method of accounting follows:

Under the cash receipts and disbursements method of accounting, only $9,000 of the $11,000 opening inventory had been included in the cost of goods sold and claimed as a deduction for the taxable years 1954 through 1957; the remaining $2,000 had been so accounted for in pre-1954 years. In order to prevent the same item from reducing taxable income twice, an adjustment of $9,000 must be made to the taxable income of 1958 under the provisions of section 481(a) and § 1.481-1. Since the change in method of accounting was not initiated by the taxpayer, the $2,000 of opening inventory which had been included in cost of goods sold in pre-1954 years is not taken into account. Taxable income for 1958 is accordingly increased by $9,000 under section 481(a) to $13,400. Assuming that the tax on $13,400 is $4,002 and that the tax on $4,400 (income without the adjustment) is $944, the increase in tax attributable to the adjustment, if taken into account for the taxable year of the change, would be the difference between the two, or $3,058. Since the adjustment required by section 481(a) and § 1.481-1 ($9,000) increases taxable income by more than $3,000, the increase in tax for the taxable year 1958 attributable to the adjustment of $9,000 (i.e., $3,058) may be limited under the provisions of section 481(b) (1) or (2). See examples (2) and (3).

Assume that the taxpayer in Example 1 used the cash receipts and disbursements method of accounting in computing taxable income for the years 1956 and 1957 and that the taxable income for these years determined under such method was $4,000 and $6,000, respectively. The section 481(b)(1) limitation on tax with a pro rata three-year allocation of the $9,000 adjustment is computed as follows:

Since this increase in tax of $2,596 is less than the increase in tax attributable to the inclusion of the entire adjustment in the income for the taxable year of the change ($3,058), the limitation provided by section 481(b)(1) applies, and the total tax for 1958, the taxable year of the change, if section 481(b)(2) does not apply, is determined as follows:

(i) Assume the same facts as in Example 1 and, in addition, assume that the taxpayer used the cash receipts and disbursements method of accounting in computing taxable income for the years 1953 through 1957; that he established his taxable income under the new method for the taxable years 1953, 1954, and 1957, but did not have sufficient records to establish his taxable income under such method for the taxable years 1955 and 1956. The original taxable income and taxable income as redetermined are as follows:

As in examples (1) and (2), the total adjustment under section 481(a) is $9,000. Of the $9,000 adjustment, $4,000 may be allocated to 1957, which is the only year consecutively preceding the taxable year of the change for which the taxpayer was able to establish his income under the new method. Since the income cannot be established under the new method for 1956 and 1955, no allocation may be made to 1954 or 1953, even though the taxpayer has established his income for those years under the new method of accounting. The balance of $5,000 ($9,000 minus $4,000) must be allocated to 1958.

(ii) The limitation provided by section 481(b)(2) is computed as follows: The tax for 1957, based on taxable income of $6,000, is assumed to be $1,360. Under the new method, based on taxable income of $10,000, the tax for 1957 is assumed to be $2,640, the increase attributable to $4,000 of the $9,000 section 481(a) adjustment being $1,280, ($2,640 minus $1,360). The tax for 1958, computed on the basis of taxable income of $4,400 (determined under the new method), is assumed to be $944. The tax computed for 1958 on taxable income of $9,400 ($4,400 plus the $5,000 adjustment allocated to 1958) is assumed to be $2,436, leaving a difference of $1,492 ($2,436 minus $944) attributable to the inclusion in 1958 of the portion of the total adjustment to be taken into account which could not be properly allocated to the taxable year or years consecutively preceding 1958.

(iii) The tax attributable to the adjustment is determined by selecting the smallest of the three following amounts:

The final tax for 1958 is then $3,540 computed as follows:

Assume that X Corporation has maintained its books of account and filed its income tax returns using the cash receipts and disbursements method of accounting for the years 1953 through 1957. The corporation secures permission to change to an accrual method of accounting for the calendar year 1958. The following tabulation presents the data with respect to the taxpayer's income for the years involved:

As indicated above, taxable income for 1953 and 1954, as determined under the cash receipts and disbursements method of accounting, was $2,000 and $4,000, respectively, and after application of the net operating loss carryback from 1955, the taxable income was reduced to zero in 1953 and to $1,000 in 1954. The taxpayer was unable to establish taxable income for these years under an accrual method of accounting; however, under section 481(b)(3)(A), increases or decreases in the tax for taxable years to which no adjustment is allocated must, nevertheless, be taken into account to the extent the tax for such years would be affected by a net operating loss determined with reference to taxable years to which adjustments are allocated. The total amount of the adjustments required under section 481(a) and attributable to the taxable years 1953 through 1957 in this example is assumed to be $10,000. The redetermination of taxable income established by the taxpayer for the taxable years 1955, 1956, and 1957 appears under the heading “Taxable income established under accrual method” in the above tabulation. The tabulation assumes that the taxpayer has been able to recompute the income for those years so as to establish a net adjustment of $9,000, which leaves a balance of $1,000 unaccounted for. In accordance with the requirements of section 481(b)(2), the $1,000 amount is allocated to 1958, the taxable year of the change. The following computations are necessary in order to determine the tax attributable to the adjustments under section 481(a):

Since the limitation under section 481(b)(2) ($3,880) on the amount of tax attributable to the adjustments is applicable, the final tax for the taxable year of the change is computed by adding such amount to the tax for that year computed without the inclusion of any amount attributable to the adjustments, that is, $46,500 plus $3,880, or $50,380.
