IRS Form 1125A - Cost of Goods Sold

IRS Form 1125A is used to figure and deduct cost of goods sold for certain entities filing with the IRS. If an entity uses LIFO, it must enter the closing LIFO Reserve on line 9d(ii).

The form collects details such as inventory at the Beginning of Year (line 1), purchases (line 2), additional Section 263A Costs (line 4), and the final Cost of Goods Sold amount (line 8). It also requires checking applicable Inventory Valuation Methods on line 9.

Common confusion points

What counts as a per-unit retain allocation for cooperatives?

It is any allocation from the cooperative to a patron for products marketed for that patron without reference to the cooperative net earnings.

Verify this definition against your specific cooperative's accounting.

When should a cooperative deduct a nonqualified per-unit retain certificate?

No deduction is allowed at issuance, but the deduction can be taken in the year the certificate is redeemed, subject to its stated dollar amount (per section 1383).

Ensure you are tracking redemption dates accurately for line 5.

Does my small business taxpayer need to use an accrual method?

Generally, yes; inventories are required at beginning and end of each tax year if production, purchase, or sale is income-producing.

Check lines 9a(iv) through 9a(vi) to see which specific alternative method applies.

What do I include on line 5 ('Other costs')?

Costs that require an attached schedule must be included on line 5.

Ensure the supporting schedule is correctly referenced and complete.

If my business uses LIFO, where does the closing reserve go?

The closing LIFO Reserve is entered on line 9d(ii) (as per prior knowledge/context).

Confirm this placement matches your specific filing requirements for Form 1125A Rev. November 2024.

What triggers the need to file Form 1125-A?

An entity must complete and attach Form 1125-A if it reports a deduction for cost of goods sold.
