Title 26 › Subtitle A — Income Taxes › CHAPTER 1 — NORMAL TAXES AND SURTAXES › Subchapter E — Accounting Periods and Methods of Accounting › PART II — METHODS OF ACCOUNTING › Subpart D — Inventories › § 473
Lets a business that uses the LIFO way of counting inventory lower its taxable income for a year when it has a big drop in inventory because it could not replace goods. If the business chooses this rule and later replaces those goods during the allowed replacement period and shows the replacements in its year-end inventory, the business’s gross income for the year of the drop is changed. If the total cost to replace the goods is more than the cost shown for them at the start of the drop year, gross income for that drop year is lowered by the difference. If the replacement cost is less than the start-of-year cost, gross income for the drop year is increased by the difference. The choice to use this rule must follow the Treasury’s rules, is binding, and cannot be undone. Key terms and rules in one line each: qualified liquidation — a drop in closing versus opening inventory mainly caused by a qualified inventory interruption; qualified inventory interruption — situations the Secretary finds (after consulting others) such as energy rules, embargoes, or major trade breaks that made replacement hard, announced in the Federal Register; liquidation year — the year the drop happened; replacement year — any year in the replacement period before replacement is finished; replacement period — the shorter of the 3 taxable years after the drop year or a period the Secretary sets; LIFO method — the inventory method under section 472. Replacements are treated as filling the most recently liquidated items in the order acquired and are recorded at the cost basis of the items they replace. The Secretary will issue coordinating rules and special timing and interest rules for assessments and refunds.
