A filled-in Form 1125-A example: a corporation figures its cost of goods sold

Form 1125-A example filled out, example: a corporation figures its cost of goods sold
Sample Widget Supply Inc., a corporation that files Form 1120 and reports a deduction for cost of goods sold, completes Form 1125-A to attach to that return. The example assumes that the company did not change its method of accounting and withdrew no purchases for personal use; that the rules of section 263A do not apply to it, so it has no additional section 263A costs (line 4 is 0) and line 9e is No; that it has no other costs (line 5 is 0) and is not a cooperative; that it values closing inventory at cost only, so only box 9a(i) is checked and none of the other boxes on line 9a; that it had no writedown of subnormal goods and did not adopt the LIFO method this tax year and does not use it, so boxes 9b and 9c are left unchecked and lines 9d(i) and 9d(ii) are left empty (a filer that uses LIFO must enter both amounts); and that there was no change in determining quantities, cost, or valuations, so line 9f is No. Line 6 adds lines 1 through 5 and line 8 subtracts line 7 from line 6. Every name, number and amount in the example is made up.

If there is a difference between last year's closing inventory and the refigured amount, attach an explanation and take it into account when figuring any section 481(a) adjustment.

The production of real property and tangible personal property for use in its trade or business or in an activity engaged in for profit.

Line 6, Total: add lines 1 through 5.

Filers of Form 1120, 1120-C, 1120S, and 1065, enter cost of goods sold on page 1, line 2. Filers of Form 1120-F, enter cost of goods sold on Section II, line 2.

Line 9a

Form 1125-A example filled out, line 9a

Line 9a, Inventory methods: (i) Cost, (ii) Lower of cost or market, (iii) Other (specify method used and attach explanation). For certain small business taxpayers, alternative methods of accounting for inventories: (iv) Non-incidental materials and supplies method, (v) AFS method, (vi) Non-AFS method. Complete line 9 as follows: check all applicable boxes on lines 9a(i) through 9a(iii) to indicate how the value of an inventory item is figured.

For certain small business taxpayers that have adopted or changed to an alternative accounting method that is an exception to the general inventory requirements described in the General Instructions, check a box on lines 9a(iv) through 9a(vi) in lieu of checking an applicable box on lines 9a(i) through 9a(iii).

Inventories can be valued at cost, cost or market value (whichever is lower), or any other method approved by the IRS that conforms to the requirements of the applicable regulations.

Under lower of cost or market, the term “market” (for normal goods) means the current bid price prevailing on the inventory valuation date for the particular merchandise in the volume usually purchased by the filer.

For a manufacturer, market applies to the basic elements of cost-raw materials, labor, and burden.

If section 263A applies, the basic elements of cost must reflect the current bid price of all direct costs and all indirect costs properly allocable to goods on hand at the inventory date.

Common mistake: The methods on line 9a are methods of accounting. Any method, once established, cannot be changed in a later year without requesting a change in accounting method.

Line 9b, Lines 9c and 9d

Form 1125-A example filled out, line 9b, Lines 9c and 9d

Line 9b, Check if there was a writedown of subnormal goods: inventory may be valued below cost when the merchandise is unsalable at normal prices or unusable in the normal way because the goods are subnormal due to damage, imperfections, shopwear, change of style, odd or broken lots, or other similar causes, including second-hand goods taken in exchange.

The goods may be valued at the bona fide selling price, minus the direct cost of disposition (but not less than scrap value).

Bona fide selling price means actual offering of goods during a period ending not later than 30 days after inventory date.

Lines 9c and 9d, LIFO method: check the LIFO box on line 9c if the LIFO inventory method was adopted this tax year for any goods (if checked, attach Form 970).

If the LIFO inventory method was used for this tax year, on line 9d(i) enter the amount of total closing inventories figured under section 472.

If the LIFO inventory method was used for this tax year, on line 9d(ii) enter the closing LIFO Reserve. The closing LIFO Reserve is figured by subtracting the LIFO value of the inventory subject to a LIFO method that is on hand at the end of the tax year from the first-in, first-out (FIFO) value of that inventory.

If the closing LIFO Reserve amount is negative, place the amount on line 9d(ii) in parentheses.

Line 9e and Line 9f

Form 1125-A example filled out, line 9e and Line 9f

Line 9e: if property is produced or acquired for resale and the rules of section 263A apply to the corporation, cooperative, partnership, or other applicable entity, check the “Yes” box on line 9e.

Line 9f: Was there any change in determining quantities, cost, or valuations between opening and closing inventory? If “Yes,” attach explanation.

Situations: small business taxpayers

Small business taxpayers

If inventories are required, you generally must use an accrual method of accounting for sales and purchases of inventory items. Exception for small business taxpayers. A small business taxpayer can account for inventory by treating the inventory as non-incidental materials and supplies (line 9a(iv)), or conforming to its treatment of inventory in an applicable financial statement (as defined in section 451(b)(3)) (line 9a(v)). If it does not have an applicable financial statement, a small business taxpayer can use the method of accounting used in its books and records prepared according to its accounting procedures (line 9a(vi)).

A small business taxpayer is not required to capitalize costs under section 263A. See section 263A(i).
