§ 1.6655-2. Annualized income installment method.

(i) Corporation ABC, a calendar year taxpayer, uses an accrual method of accounting and the annualized income installment method under section 6655(e)(2)(A)(i) to calculate all of its required installment payments for its 2008 taxable year. ABC has adopted a plan under which ABC pays an annual bonus to its employees. As of March 31, 2008, ABC estimates that it will pay a year-end bonus of $500,000 to its employees if earnings remain constant throughout the tax year. ABC does not pay any of the estimated bonus liability as of March 31, 2008. On October 31, 2008, ABC declares a $600,000 bonus to its employees which is paid out on November 15, 2008, and properly deducted in ABC's December 31, 2008, tax year. No other bonus liabilities are incurred by ABC during the tax year.

(ii) Under the general rule provided in paragraph (f)(2)(i) of this section, ABC is required to allocate its employee bonus liability in a reasonably accurate manner for annualization purposes. Under paragraph (f)(2)(iii) of this section, ABC's employee bonus liability will be deemed to be allocated in a reasonably accurate manner if the item is allocated ratably throughout the taxable year. Therefore, ABC is permitted to recognize a $150,000 bonus deduction (one quarter of the $600,000 bonus liability properly recognized by ABC in the tax year ending December 31, 2008) in the first annualization period ending March 31, 2008.

(i) Corporation ABC, a calendar year taxpayer, uses an accrual method of accounting and the annualized income installment method under section 6655(e)(2)(A)(i) to calculate all of its required installment payments for its 2008 taxable year. ABC has adopted a plan under which ABC pays an annual bonus to its employees. ABC's employee bonus plan generally calls for an annual bonus equal to 2% of earnings. A bonus reserve for this amount is reported each quarter in ABC's non-tax books and records. ABC's quarterly revenues throughout the year are $10,000,000; $6,000,000; $7,000,000; and $7,000,000 respectively. As of March 31, 2008, ABC estimates that it will pay a year-end bonus of $800,000 ($10,000,000 × 4 × 2%) to its employees if earnings remain constant throughout the year. ABC does not pay any of the estimated bonus payment as of March 31, 2008. On December 31, 2008, ABC declares a $600,000 bonus to its employees which is paid out on January 15, 2009, and properly deducted in ABC's December 31, 2008, tax year.

(ii) Under the general rule provided in paragraph (f)(2)(i) of this section, ABC must allocate its employee bonus liability in a reasonably accurate manner for annualization purposes. Under paragraph (f)(2)(iii) of this section, ABC's employee bonus liability will be deemed to be allocated in a reasonably accurate manner if the allocation provides a reasonable estimate of taxable income based upon the facts known as of the end of the annualization period. Based upon its earnings activities and other information available as of March 31, 2008, ABC estimated that its total deduction for employee bonuses for the taxable year ending December 31, 2008, would be $800,000 ($10,000,000 first quarter earnings × 4 × 2%). Allocating $200,000 ($10,000,000 × 2%) of ABC's annual bonus liability of $600,000 to ABC's first quarter based upon earnings during the quarter represents a better matching of ABC's bonus expense to earnings in the quarter as compared to allocating $150,000 to ABC's first quarter under a ratable accrual method and is consistent with the allocation provided in ABC's non-tax books and records. Accordingly, allocating ABC's employee bonus deductions based upon ABC's earnings will be considered allocated in a reasonably accurate manner.

(i) Corporation ABC, a calendar year taxpayer, uses an accrual method of accounting and the annualized income installment method under section 6655(e)(2)(A)(i) to calculate all of its required installment payments for its 2008 taxable year. ABC has adopted a plan under which ABC pays a bonus to its employees each quarter based upon earnings for that quarter. On March 31, 2008, ABC pays out $2,000,000 to its employees as a quarterly bonus based upon the earnings of ABC for the period January 1, 2008, through March 31, 2008. The $2,000,000 bonus is recognized as an expense on ABC's audited financial statements in the quarter ending March 31, 2008. As of March 31, 2008, ABC anticipates that its earnings will continue throughout the year resulting in future quarterly bonus payments in 2008 similar to the $2,000,000 first quarter payment.

(ii) Under the general rule provided in paragraph (f)(2)(i) of this section, ABC is required to allocate its employee bonus liability in a reasonably accurate manner for annualization purposes. Under paragraph (f)(2)(iii) of this section , ABC's employee bonus liability will be deemed to be allocated in a reasonably accurate manner if the item is allocated ratably throughout the taxable year. Therefore, ABC may recognize a $500,000 bonus deduction (one quarter of the $2,000,000 bonus liability properly recognized by ABC in the tax year ending December 31, 2008) in the first annualization period ending March 31, 2008 (as well as one quarter of any additional bonus liability properly recognized by ABC in the tax year ending December 31, 2008).

(iii) In addition, paragraph (f)(2)(iii) of this section provides that an allocation will be considered reasonable if the allocation provides an accurate estimate of taxable income for the taxable year based upon the facts known as of the end of the annualization period. Based upon its earnings activities and other information available as of March 31, 2008, ABC estimates that its total deduction for employee bonuses for the taxable year ending December 31, 2008, would be $8,000,000. In addition, the $2,000,000 bonus liability became fixed and determinable during the first quarter. Allocating $2,000,000 to ABC's first quarter earnings is also consistent with ABC's non-tax books and records and represents a better matching of ABC's bonus expense to earnings in the quarter as compared to a ratable accrual. Accordingly, allocating ABC's bonus liability based upon earnings will be considered a reasonably accurate manner for estimated tax purposes.

(i) Corporation ABC, a calendar year taxpayer, uses an accrual method of accounting with the recurring item exception and the annualized income installment method under section 6655(e)(2)(A)(i) to calculate all of its required installment payments for its 2009 taxable year. ABC regularly incurs rebate obligations related to the sale of its products. Rebate coupons that are received and validated by ABC are generally paid in the following month. During the tax year ending December 31, 2009, ABC received, validated and paid $400,000 in rebates. In addition, as of the end of December 31, 2009, ABC had received and validated $100,000 in rebate claims that were paid in January of 2010 and deducted in ABC's December 31, 2009, tax year under the recurring item exception. Therefore, ABC properly recognized a $500,000 rebate liability deduction on ABC's December 31, 2009, tax return.

(ii) Under the rule provided in paragraph (f)(2)(ii) of this section, an item must be allocated in a reasonably accurate manner if any portion of the item is deducted under the recurring item exception. Therefore, ABC will be required to allocate its entire $500,000 rebate liability deduction in a reasonably accurate manner as defined in paragraph (f)(2)(iii) of this section.

Corporation ABC, a calendar year taxpayer, uses an accrual method of accounting and the annualized income installment method under section 6655(e)(2)(A)(i) to calculate all of its required installment payments for its 2008 taxable year. ABC has licensed technology from Corporation XYZ. Pursuant to the license agreement, ABC pays a license fee to XYZ equal to $.01 for every dollar of gross receipts earned by ABC. For 2008, ABC projects gross receipts of $200,000,000, of which $100,000,000 is earned by March 31, 2008. Pursuant to paragraph (f)(1) of this section, a license fee expense of $1,000,000 ($100,000,000 × $.01) is incurred by March 31, 2008, and may be taken into account for purposes of determining the taxable income to be annualized in computing ABC's first annualized income installment.

Same facts as Example 1 except that ABC does not earn any gross receipts by March 31, 2008. In accordance with paragraph (f)(1) of this section, because the license fee expense was not incurred under § 1.461-1(a)(2) by the last day of the annualization period, no license fee expense is taken into account for purposes of determining the taxable income to be annualized in computing ABC's first annualized income installment, which is based on the income and deductions from the first three months of the taxable year.

Corporation ABC, a calendar year taxpayer, uses an accrual method of accounting and the annualized income installment method under section 6655(e)(2)(A)(i) to calculate all of its required installment payments for its 2008 taxable year. As of December 31, 2007, ABC had a $100,000 account receivable due from XYZ related to the sale of goods from ABC to XYZ during 2007. On March 30, 2008, ABC determined that its receivable from XYZ was worthless under section 166 and the regulations. No other receivables were determined to be worthless between January 1, 2008, and March 31, 2008. In accordance with paragraph (f)(1) of this section, a $100,000 bad debt write-off is taken into account for purposes of determining the taxable income to be annualized in computing ABC's first annualized income installment.

Same facts as Example 3 except that ABC determines that the receivable from XYZ was worthless under section 166 and the regulations on April 10, 2008. As of March 31, 2008, ABC had not determined that any receivables were worthless under section 166 and the regulations. In accordance with paragraph (f)(1) of this section, the $100,000 bad debt expense attributable to the receivable from XYZ is not taken into account for purposes of determining the taxable income to be annualized in computing ABC's first annualized income installment, which is based on the income and deductions from the first three months of the taxable year, because the receivable from XYZ became worthless after the last day of the annualization period.

(i) Corporation ABC, a calendar year taxpayer, uses an accrual method of accounting and uses the annualized income installment method under section 6655(e)(2)(A)(i) to calculate all of its required installment payments for its 2008 taxable year. On March 1, 2008, the board of directors of ABC makes a binding, irrevocable commitment to fund a minimum contribution of $10,000,000 to ABC's qualified retirement plan by March 14, 2009. ABC remits a $1,000,000 payment to the retirement plan on March 1, 2008, and a $9,000,000 payment on March 3, 2009. ABC does not incur any other related retirement plan deductions during its 2008 taxable year.

(ii) Under the rule provided in paragraph (f)(2)(i) of this section, ABC's employer deduction for payment made to the qualified plan must be allocated throughout the tax year for estimated tax purposes in a reasonably accurate manner. Therefore, ABC will not be permitted to allocate the $10,000,000 deduction to its first installment period. Under paragraph (f)(2)(iii) of this section, ABC's qualified plan deduction will be deemed to be allocated in a reasonably accurate manner if the item is allocated ratably throughout the taxable year. Therefore, ABC will be permitted to allocate $2,500,000 of its qualified plan deduction in its first installment period.

(i) Corporation ABC, a calendar year taxpayer, uses an accrual method of accounting and does not capitalize qualifying costs under the exception provided for in § 1.263(a)-4(f). ABC uses the annualized income installment method under section 6655(e)(2)(A)(i) to calculate all of its required installment payments for its 2008 taxable year. On July 1, 2008, ABC purchases an annual business license from State X which permits ABC to operate its business in State X from July 1, 2008, through June 30, 2009. An annual payment of $12,000 is due on July 1, 2008, and ABC pays the fee on this date. ABC has not elected out of the 12-month rule provided by § 1.263(a)-4(f) and therefore ABC is not required to capitalize any amount paid for the license and will recognize a $12,000 deduction for the tax year ending December 31, 2008, with respect to this license.

(ii) Under the rule provided in paragraph (f)(2)(ii) of this section, ABC's $12,000 business license expense must be allocated in a reasonably accurate manner because ABC utilizes the 12-month rule exception provided for in the § 1.263(a)-4(f). Under paragraph (f)(2)(iii) of this section, ABC's deduction will be deemed to be allocated in a reasonably accurate manner if the item is allocated ratably throughout the taxable year. Therefore, ABC will be permitted to allocate $3,000 of its business license deduction in its first installment period.

(i) Corporation ABC, a calendar year taxpayer, uses an accrual method of accounting and the annualized income installment method under section 6655(e)(2)(A)(i) to calculate all of its required installment payments for its 2008 taxable year. ABC owns real property in State Y and uses the real property in its trade or business. ABC incurs a $400,000 deduction for State Y real estate taxes during ABC's December 31, 2008, taxable year. ABC has elected to recognize its real property taxes ratably under section 461(c).

(ii) Under the rule provided in paragraph (f)(2)(i) of this section, ABC's $400,000 real property tax liabilities must be allocated in a reasonably accurate manner. However, paragraph (f)(2)(iv) of this section provides that with respect to real property taxes for which an election has been made under section 461(c), ratable accrual is the only method which will be considered a reasonably accurate method. Therefore, ABC will be required to allocate its $400,000 real property taxes ratably for estimated tax purposes and thus $100,000 will be allocated to the ABC's first annualized income installment.

Corporation ABC, a calendar year taxpayer, uses an accrual method of accounting and the annualized income installment method under section 6655(e)(2)(A)(i) to calculate all of its required installment payments for its 2008 taxable year. ABC has a net operating loss carryover to 2008 of $2,000,000. ABC's taxable income from January 1, 2008, through March 31, 2008, without regard to any net operating loss deduction, is $1,500,000 (pre-NOL taxable income). Under the special rule for net operating loss deductions provided in paragraph (f)(3)(ii) of this section, the NOL deduction is treated as an extraordinary item incurred on the first day of ABC's December 31, 2008, tax year. Therefore, the NOL deduction is taken into account after annualization for purposes of determining ABC's first annualized income installment.

(i) Corporation ABC, a calendar year taxpayer, uses an accrual method of accounting and the annualized income installment method under section 6655(e)(2)(A)(i) to calculate all of its required installment payments for its 2008 and 2009 taxable years. ABC is in the business of giving dancing lessons and receives advance payments. For Federal income tax purposes, ABC uses the Deferral Method provided in section 5.02 of Rev. Proc. 2004-34 for the advance payments it receives for dance lessons. On November 1, 2008, ABC receives an advance payment of $2,400 for a 2-year contract commencing on November 1, 2008, and providing for up to 24 individual, 1-hour lessons. ABC provides 2 lessons in 2008, 12 lessons in 2009, and 10 lessons in 2010. ABC recognizes $200 in revenues in its financial statements for the last quarter of 2008. ABC recognizes $300 in revenues in its financial statements for each quarter of 2009 for a total of $1,200 in 2009. ABC recognizes the remaining $1,000 in revenues in its financial statements during 2010. For tax purposes, ABC recognizes $200 into revenue in 2008 and $2,200 into revenue in 2009 under Rev. Proc. 2004-34. See § 601.601(d)(2)(ii)(b).

(ii) Pursuant to paragraph (f)(3)(i)(B) of this section, ABC is not required to take into account any of the advance payment for purposes of computing any required installment payment for ABC's 2008 taxable year because no part of the $2,400 advance payment was recognized as income in ABC's financial statements during the first nine months of ABC's 2008 taxable year. In 2009, ABC must take into account $300 of revenue for purposes of computing its first and second required installment payments, $600 of revenue for purposes of computing its third required installment payment and $900 for purposes of computing its fourth required installment payment. Pursuant to paragraph (f)(3)(i)(B) of this section, the remaining deferred revenue is recognized on December 31, 2009, for purposes of computing ABC's annualized income installments for 2009.

Corporation ABC, a calendar year taxpayer, uses an accrual method of accounting and the annualized income installment method under section 6655(e)(2)(A)(i) to calculate all of its required installment payments for its 2008 taxable year. On December 20, 2008, ABC files a Form 3115 requesting permission to change its method of accounting. The requested change results in a negative section 481(a) adjustment of $80,000. ABC subsequently receives the consent of the Commissioner to make the change and therefore, the negative $80,000 section 481(a) adjustment is properly recognized in ABC's tax return for the year ending December 31, 2008. Under paragraph (f)(3)(ii) of this section ABC is permitted to recognize the negative $80,000 section 481(a) adjustment as an extraordinary item occurring on January 1, 2008 (the first day of ABC's December 31, 2008, tax year), or December 20, 2008 (the date ABC filed the Form 3115). ABC chooses to recognize the negative $80,000 section 481(a) adjustment as an extraordinary item occurring in January 1, 2008. Accordingly, $80,000 of the negative section 481(a) adjustment is taken into account after annualization for purposes of determining ABC's first annualized income installment. In addition, under § 1.6655-6(b), ABC is required to use its new method of accounting as of January 1, 2008 for estimated tax purposes, consistent with the recognition of the section 481(a) adjustment for estimated tax purposes. Therefore, ABC will be required to use the new method of accounting in determining taxable income to be annualized in computing ABC's first annualized income installment.

Corporation ABC, a calendar year taxpayer, uses an accrual method of accounting and uses the annualized income installment method under section 6655(e)(2)(A)(i) to calculate all of its required installment payments for its 2008 taxable year. On June 15, 2008, ABC files a Form 3115 requesting permission to change its method of accounting. The requested change results in a positive section 481(a) adjustment of $240,000. ABC subsequently receives the consent of the Commissioner to make the change and therefore, $60,000 of the section 481(a) adjustment (one quarter of the positive $240,000 section 481(a) adjustment) is properly recognized in ABC's tax return for the year ending December 31, 2008. Under paragraph (f)(3)(ii) of this section, ABC is permitted to recognize the positive $60,000 section 481(a) adjustment as an extraordinary item occurring on January 1, 2008 (the first day of ABC's December 31, 2008, tax year), or June 15, 2008 (the date ABC filed the Form 3115). ABC chooses to recognize the positive $60,000 section 481(a) adjustment as an extraordinary item occurring on June 15, 2008. Accordingly, the $60,000 positive section 481(a) adjustment is not taken into account for purposes of determining ABC's first annualized income installment. However, in all futures years any portion of the section 481(a) adjustment related to this change in method of accounting will be treated as an extraordinary item occurring on the first day of the tax year under paragraph (f)(3)(ii) of this section. In addition, under § 1.6655-6(b), ABC is required to use its new method of accounting as of June 15, 2008 for estimated tax purposes, consistent with the recognition of the section 481(a) adjustment for estimated tax purposes. Therefore, ABC will be required to use the new method of accounting (as of the beginning of the tax year) for purposes of determining taxable income to be annualized in computing ABC's third and fourth annualized income installments (which are based upon annualization periods that include June 15, 2008.)

Corporation ABC, a calendar year taxpayer, uses an accrual method of accounting and the annualized income installment method under section 6655(e)(2)(A)(i) to calculate all of its required installment payments for its 2008 taxable year. On May 10, 2008, ABC reaches a settlement agreement with XYZ over a tort action filed by ABC. As a result, ABC receives a payment of $10,000,000 on June 15, 2006, that is recognized as income by ABC. The settlement of a tort action is an extraordinary item defined in paragraph (f)(3)(ii)(A) of this section. Accordingly, the $10,000,000 of income will be taken into account by ABC on May 10, 2008, for purposes of computing ABC's annualized income installments for 2008. Therefore, the $10,000,000 settlement will only be taken into account in computing ABC's third and fourth annualized income installments (which are based upon annualization periods that include May 10, 2008). In addition, the $10,000,000 settlement income will be taken into account as an extraordinary item of income after annualization for purposes of determining ABC's third and fourth annualized installment payments.

Corporation ABC, a calendar year taxpayer, uses an accrual method of accounting and the annualized income installment method under section 6655(e)(2)(A)(i) to calculate all of its required installment payments for its 2008 taxable year. ABC projects its annualized tax for its 2008 taxable year, based on annualizing ABC's taxable income for its first annualization period from January 1, 2008, through March 31, 2008, to be $1,500,000 before reduction for any credits. ABC has an unused section 38 credit from 2007 for increasing research activities from 2007 of $500,000 that is carried over to 2008. For purposes of determining ABC's first annualized income installment, ABC's annualized tax for 2008 is $1,000,000, determined as the tax for the taxable year computed by placing on an annualized basis ABC's taxable income from its first annualization period from January 1, 2008, through March 31, 2008 ($1,500,000) reduced by the $500,000 credit carryover from 2007. Therefore, ABC's first required installment payment for 2008 is $250,000 ($1,000,000 × 25%).

Corporation ABC, a calendar year taxpayer, uses an accrual method of accounting and the annualized income installment method under section 6655(e)(2)(A)(i) to calculate all of its required installment payments for its 2008 taxable year. ABC projects its annualized tax for its 2008 taxable year, based on annualizing ABC's taxable income for its first annualization period from January 1, 2008, through March 31, 2008, to be $2,000,000 before reduction for any credits. ABC has historically earned a section 41 credit for increasing research activities and, for 2008, ABC estimates that it will earn a credit for increasing research activities under section 41 of $1,200,000. However, pursuant to paragraph (f)(3)(iii) of this section, if ABC were to annualize all components involved in computing the current year credit based on ABC's activity from January 1, 2008, through March 31, 2008, ABC would generate a credit of $1,600,000 for 2008. For purposes of determining ABC's first annualized income installment, ABC's annualized tax for 2008 is $400,000, determined as the tax for the 2008 taxable year ($2,000,000) computed by placing on an annualized basis ABC's taxable income from its first annualization period January 1, 2008, through March 31, 2008, reduced by a $1,600,000 current year section 41 credit from increasing research activities. Therefore, ABC's first required installment payment for 2008 is $100,000 ($400,000 × 25%).

Same facts as Example 14 except that ABC does not begin any research activities until April 3, 2008, and will not incur any research expenses described in paragraph (f)(1)(ii) of this section. As a result, if ABC were to annualize all components involved in computing the current year credit based on ABC's activity from January 1, 2008, through March 31, 2008, ABC would generate no section 41 research credit for purposes of determining its first annualized income installment. Pursuant to paragraph (f)(3)(iii) of this section, ABC cannot take into account any credit for its first annualization period because ABC did not incur any qualified research expenses by the last day of the first annualization period. Accordingly, for purposes of determining ABC's first annualized income installment, ABC's annualized tax for its first annualization period January 1, 2008, through March 31, 2008, is $2,000,000. Therefore, ABC's first required installment payment for 2008 is $500,000 ($2,000,000 × 25%).

Corporation ABC, a calendar year taxpayer that began business on January 2, 2007, adopted an accrual method of accounting and will use the annualized income installment method under section 6655(e)(2)(A)(i) to calculate all of its required installment payments for its 2008 taxable year. On January 2, 2007, ABC purchased and placed in service a tangible depreciable asset that costs $50,000 and is 5-year property under section 168(e). ABC depreciates its 5-year property placed in service in 2007 under the general depreciation system using the 200-percent declining balance method, a 5-year recovery period, and the half year convention. On January 2, 2008, ABC purchased and placed in service qualified Gulf Opportunity Zone property (GO Zone property) that costs $30,000 and is 5-year property under section 168(e). ABC will depreciate its 5-year property placed in service in 2008 under the general depreciation system using the 200-percent declining balance method, a 5-year recovery period, and the half-year convention. ABC will deduct the 50% additional first year depreciation deduction under section 1400N(d) with respect to the GO Zone property. For tax year 2007, ABC takes a depreciation deduction under section 168 of $10,000 ($50,000 × 20% = $10,000). ABC does not anticipate being subject to the mid-quarter convention for the 2008 taxable year, does not anticipate making any depreciation elections for any class of property, does not anticipate making a section 179 election, does not anticipate any sales or other dispositions of depreciable property, and no events have occurred, nor does ABC know, based on all relevant information available as of the due date of ABC's first required installment for 2008, of any event that will occur to cause ABC's 2008 taxable year to be a short taxable year. The optional amounts of depreciation expense ABC may take into account for its first annualized income installment for its 2008 taxable year are determined as follows:

(i) General rule—Estimated annual depreciation. In accordance with the general rule provided in paragraph (f)(3)(iv)(A) of this section, ABC may take a depreciation expense of $8,500 ($34,000 × 3/12 = $8,500) into account in computing ABC's January 1, 2008, through March 31, 2008, taxable income. ABC's estimated annual depreciation expense for 2008 of $34,000 is computed as follows: $15,000 for the 50% additional first year depreciation deduction under section 1400N(d) ($30,000 × 50% = $15,000) plus annual depreciation of $16,000 ($40,000 × 40% = $16,000) and $3,000 ($15,000 × 20% = $3,000). Under paragraphs (c)(3) and (f)(3)(iv)(C) of this section, ABC may not consider its first annualization period to be a short taxable year for purposes of determining the depreciation allowance for such annualization period.

(ii) Safe Harbor—Proportionate depreciation allowance.
