What Is Dead Stock and How to Clear It for the Least Loss

Dead stock is inventory you no longer expect to sell at its normal price within any reasonable time. It still takes up a bin, still gets counted, and often still sits on the balance sheet at what you paid for it, even though the accounting rules say it should already have been written down.

The short answer to clearing it: find it by age and sales history, decide quickly, and keep the paperwork. Clearing dead stock rarely makes money; the goal is to lose as little as possible and to have the loss count in the right year. In the US, that second part depends on evidence the warehouse produces: offers, sales and disposal records with dates on them.

This guide is for the person who runs the floor and gets asked, every quarter, what to do about the stuff at the back.

What counts as dead stock?

There is no single standard definition, so set your own and write it down. A workable one has three parts:

• No customer shipments for a set number of days at the SKU level, not the product family. Pick a number that fits your selling cycle; a seasonal apparel brand and a spare-parts business will not pick the same one.
• No open demand: no open orders, no planned promotion, no wholesale customer who buys it once a year.
• No realistic path back to full price: the style has changed, a newer version replaced it, the packaging changed, or the shelf life left is too short for your channels.

Slow-moving stock is different. It still sells, just below plan. The fix there is buying less and moving it out of prime pick locations, not clearing it.

US tax rules cover only part of this. Regulation 26 CFR 1.471-2(c) gives special treatment to goods that cannot be sold at normal prices "because of damage, imperfections, shop wear, changes of style, odd or broken lots, or other similar causes". Stock that is merely excess does not qualify on that basis. More below.

How do you find dead stock on the floor?

Start with two numbers per SKU per location: the date of the last customer shipment and the quantity on hand. Use the last shipment, not the last movement of any kind, because a replenishment move, a transfer or a count adjustment resets the clock on stock that has not sold.

1. Run an aging report sorted by days since the last customer shipment. Exclude stock received in the last few weeks so new arrivals do not look dead.
2. Cross it with your ABC classes. A C item that has stopped moving is the usual dead-stock candidate. An A item that has stopped moving is a signal something changed: a lost listing, a broken variant, a price problem. The method in what ABC analysis is and how it works applies directly.
3. Count it before you act. Dead stock is where record errors hide, because nobody picks from those bins. Confirm the quantity physically before you price a clearance, or you will sell stock you do not have, or write off stock that was misplaced.
4. Check condition and dates. Damage, expiry and missing parts change which exit is open to you. Record the condition on each lot or bin as you count.

The output is a list: SKU, location, quantity, cost, condition, receipt date, days since the last shipment. That list is what you clear from.

What does dead stock actually cost?

It costs the space it occupies, the capital tied up in it, the handling and counting labour, and the risk that it loses more value every month it waits. Those costs keep running every month the stock stays, and none of them stops until it leaves the building.

On Amazon, the clock is explicit. Amazon's own seller guide says its aged inventory surcharge applies to inventory "that's been in our fulfillment center for 181 days or longer", on top of the monthly storage fee, and that disposal is "a per-unit charge". Note that FBA age is counted from arrival at the fulfillment center, not from the last sale, so plan removal or disposal before day 181.

What are the ways to clear dead stock?

Roughly in the order to consider them:

Return it to the supplier. Check the purchase agreement for return or exchange terms first. A credit at or near cost, after restocking fees and freight, usually beats a deep clearance.

Sell it at a markdown through your own channels. A price you control, to customers you already have. Keep the markdown dated and the listing live, so you can show the stock was really offered at that price.

Bundle it. Pair a dead SKU with a fast mover as a gift or a kit. Every bundle needs its own SKU and pick instruction so the components come off the right bins. A bundle does not set a selling price for the dead SKU on its own, so it does not support a tax write-down.

Sell to a wholesaler or liquidator. Fast and final, but the price is low. Keep the written offer; a completed sale is stronger evidence of value than a bid.

Donate it. The tax value depends on what kind of business you are; see below.

Recycle or scrap it. The last resort, and not free. The US EPA lists batteries, pesticides, mercury-containing equipment, lamps and aerosol cans as federal "universal waste", and states can add more, so check before anything goes in a dumpster. Keep a disposal record with dates and quantities.

Before any of these, make sure you are not about to buy it again. A SKU that is dead in your data but still has replenishment set will be reordered. The reorder point guide and the safety stock guide both assume demand exists; block purchasing or mark the SKU discontinued, and check it is not a component of a live kit.

Why can't you just write it down?

On your own books you can, and often must. Under US GAAP, as amended by FASB ASU 2015-11, inventory other than LIFO or retail-method inventory is measured at "the lower of cost and net realizable value", meaning the expected selling price less "reasonably predictable costs of completion, disposal, and transportation". LIFO and retail-method inventory stay on lower of cost or market. IAS 2 uses the same lower-of-cost-and-net-realisable-value test, but unlike US GAAP it reverses the write-down if value recovers.

Tax is a different system. In Thor Power Tool Co. v. Commissioner (1979), the US Supreme Court upheld the IRS disallowing a write-down of excess inventory even though it conformed to generally accepted accounting principles. Thor had written excess parts down, mostly to scrap value, but kept them and went on selling them at original prices, scrapping only some over the following years. The Court said the regulations "demand hard evidence of actual sales and further demand that records of actual dispositions be kept."

IRS guidance for its own examiners (a Practice Unit, which is not binding law) summarises how agents apply this. "Excess or overstocked inventory is not subnormal goods, unless it is":

• "Scrapped or completely obsolete at inventory date."
• "Sold with an option to repurchase at arms-length."
• "Offered at a reduced price in inactive markets."

Goods that really are subnormal can be valued at "bona fide selling prices less direct cost of disposition", and the regulation defines a bona fide selling price as an "actual offering of goods during a period ending not later than 30 days after inventory date." The taxpayer carries the burden of proof. A reserve for "estimated depreciation" in the value of stock is listed as a method that does not comply.

None of this means the loss disappears. When the stock is finally sold or scrapped, the loss is recognised then. What the evidence decides is whether it counts this year or a later one.

Two exceptions are worth knowing. LIFO inventories are taken "at cost regardless of market value", so the market write-down route is closed for them. And businesses under the gross receipts threshold in section 448(c), which section 471(c) points to, can follow their financial statements or their own books instead of the normal inventory rules. Whether that lets a book write-down count for tax is a question for your accountant; the warehouse's job is to make sure the evidence exists either way.

When does donating dead stock make sense?

For a C corporation, it can beat liquidation. Section 170(e)(3) lets a C corporation (not an S corporation) that gives inventory to a 501(c)(3) charity, used "solely for the care" of "the ill, the needy, or infants", deduct its cost plus half of the profit it would have made, up to twice the cost, subject to the usual corporate charitable limits. The donor needs a written statement from the charity. In the Treasury regulation's own example, stock that cost $200 and is worth $1,000 would earn $200 plus $400, but the twice-cost cap limits the deduction to $400.

For most other businesses, IRS Publication 526 says the deduction for donated inventory is "the smaller of its FMV on the day you contributed it or its basis", and the donated cost comes out of opening inventory, so it is not also counted in cost of goods sold. In plain terms, donating non-food stock saves at best the same tax as scrapping it. It may still be the right thing to do, but do not plan it as a tax play. Food inventory has its own rule: the enhanced deduction is available to any trade or business, for food that meets the statute's conditions.

A clearance routine that keeps the evidence

The part most clearance advice misses is that the order of the work affects when you get the tax deduction, not just how fast the space frees up. A routine that holds up, built around your inventory date (usually year-end):

1. Before the inventory date, scrap what is unsalable and keep the disposal record: what, how many, where, when, and who took it. Scrapping after the date moves the loss into the next year.
2. Count and age everything else as close to the inventory date as you can.
3. Classify every line as slow, excess, subnormal (damaged, expired, out of style) or unsalable.
4. Have subnormal goods on offer at the price you will value them at, during a period ending no later than 30 days after the inventory date, and keep dated proof: listings, price lists, completed sales.
5. Move what remains out of prime pick faces into a clearly labelled clearance location, so it stops costing pick-path time while the sale runs.
6. Turn off replenishment for every SKU on the list.
7. Hand the file to finance, with counts, prices and dates, before they close the year.

None of this is tax advice. It is the record a warehouse should be able to produce so that whoever prepares the tax return has something to stand on.
