Dead stock can be written off when it has lost all practical value and you have the paperwork to prove it. The immediate action is simple: quarantine the affected SKUs, run a reconciled physical count, get written approval, and only then post the journal entry. Tax deductibility hinges entirely on what you can document, not on the aging report alone.
TL;DR:
- Dead stock is fully written off only when it has no market value and can be supported by physical counts, condition reports, and rejection evidence.
- Inventory with remaining partial value can sometimes be recovered through markdowns, vendor returns, bundling, or liquidation, but truly worthless items should be scrapped or donated.
- Proper documentation, including reconciled counts and rejection records, is essential to justify tax deductions and avoid IRS challenges.
- A sequence of quarantine, physical verification, recovery evaluation, approval, and disposal ensures a clear, audit-ready write-off process.
- Splitting dead stock into a markdown list for slow movers and a liquidation list for clear losses speeds up clearance and prevents future buildup.

What dead stock is and why it matters for your financials
Dead stock is inventory that will not sell through normal channels at any reasonable price: damaged goods, expired product, discontinued SKUs, or items made obsolete by a new release. It differs from slow-moving inventory, which still has a buyer somewhere, just not quickly, and from obsolete inventory, which has lost relevance but might still carry partial value through a secondary channel.
The accounting distinction matters too. A write-down reduces the carrying value of inventory that still has some worth. A write-off removes it entirely because the value has gone to zero.
Left unaddressed, dead stock does more than clutter a warehouse:
- It ties up cash that could fund better-performing SKUs.
- It accrues ongoing storage and handling costs with no offsetting revenue.
- It distorts turnover and gross margin metrics, making the business look less efficient than it operates.
- It creates risk during due diligence, when buyers or lenders discover inventory values that do not match reality.
How to identify dead stock: metrics, reports, and a physical audit checklist
Dead stock rarely announces itself. You find it by watching the right numbers and then confirming with your own eyes.
Three metrics do most of the work. Days on hand measures how long a SKU sits before selling, calculated as average inventory divided by average daily sales. Sell-through rate shows the percentage of received units sold in a given period. Weeks of supply estimates how long current stock will last at the recent sales pace. Aging buckets, typically 0 to 30, 31 to 60, 61 to 90, and 90-plus days, help flag which SKUs have crossed from slow-moving into dead territory.
Run a SKU-level sell-through report and an ABC analysis to rank items by revenue contribution. A SKU sitting in the bottom tier with zero sales over 90 to 120 days is a strong candidate for write-off review.
- Quarantine suspect SKUs so they stop appearing in available-to-sell counts.
- Pull a physical sample and inspect for damage, expiration, or packaging degradation.
- Log condition reports with photos and dates.
- Record any failed vendor return attempts or declined bulk offers as evidence the item has no remaining market.
Pro Tip: Keep a running log of declined liquidation offers. A documented “no” from a buyer is often stronger tax evidence than an internal estimate.
Step-by-step write-off workflow and correct accounting entries
A defensible write-off follows a sequence, not a single journal entry. Skipping steps is what turns a routine accounting action into an audit problem.
The workflow runs like this:
- Identify and quarantine the SKUs so they stop moving through normal sales channels.
- Perform a reconciled physical count that matches the system record to what is actually on the shelf.
- Evaluate recovery options: vendor return, markdown, bundling, liquidation, donation, or scrap.
- Estimate net realizable value, which may be zero or a small residual amount.
- Secure written approval under your inventory policy, typically from a manager and someone in finance.
- Post the journal entry.
- Dispose of, donate, or transfer the physical goods.
- Retain the full support file: counts, condition reports, approval form, and disposal receipts.
This sequence mirrors the practical workflow outlined by Lightspeed’s write-off guide, which treats the physical count and recovery-option test as the backbone of a clean write-off.
For a zero-value write-off, the standard entry debits inventory write-off expense or cost of goods sold and credits inventory for the same amount. If you already carry an allowance for obsolete inventory, debit that allowance account instead of the expense line directly, so the loss is not recorded twice.
Materiality decides where the entry lands. Smaller, routine losses can run through COGS. Larger or recurring losses deserve a dedicated write-off line so management and lenders can see the pattern clearly, a distinction NetSuite’s write-off guide spells out directly. The internal control that prevents double counting is simple: one approval form per write-off event, cross-referenced against the allowance ledger before anything is posted.
Tax implications and the documentation the IRS expects
A write-off that looks clean on your books is not automatically deductible on your return. The IRS evaluates inventory valuation against cost basis and the lower of cost or market standard, and it reserves specific treatment for what regulations call subnormal goods, meaning items that are unsalable at normal prices because of damage, imperfection, or style changes.
IRS chief counsel guidance makes clear that valuing inventory below cost requires concrete evidence: recent sales, bona fide offers, or documented condition problems. A single bulk offer from one related buyer is unlikely to hold up as proof of fair market value, because it does not reflect an arm’s-length market test.
For tax purposes, document the actual economic loss rather than leaning on an aging report alone. A reconciled count paired with dated condition reports and a record of rejected offers gives you a defensible position if the deduction is ever questioned.
The documentation checklist that supports a tax position includes:
- Reconciled physical counts tied to system records.
- Dated condition reports, with photos where possible.
- A history of markdown attempts or rejected offers.
- Disposal, destruction, or donation receipts.
- Proceeds records from any scrap or liquidation sale.
Timing matters at year-end. If you plan to claim a write-off for the current tax year, complete the physical count, approval, and journal entry before December 31, since a count performed in January supports next year’s return, not this one. Given how closely the IRS ties deductibility to evidence rather than internal judgment, a CPA review before filing is worth the hour it takes, particularly for any write-off large enough to move your reported margin.
Recovery and disposal options: when to markdown, liquidate, donate, return, or scrap
Not every dead SKU belongs in the trash. The right exit depends on how much brand risk you can tolerate and how fast you need the cash.
Markdowns and bundling preserve some brand positioning and work best for SKUs that are simply slow, not damaged or expired. You take a margin hit, but the item moves through your own channel rather than a discount reseller.
Liquidation and resale channels move inventory fast, often at a fraction of cost, and work well for the SKUs you have already tried to markdown without success. Keep the settlement statement or buyer invoice as your tax evidence.
- Donation can generate a deduction, but Shopify’s liquidation guide notes that noncash contributions over $500 require Form 8283, along with a receipt from the receiving organization.
- Vendor returns recover partial value when a supplier agreement allows it, and the return authorization itself becomes part of your support file.
- Scrapping closes out items with zero recovery value, but disposal records and, where applicable, environmental compliance documentation still belong in the file.
For electronics and other gradable goods, a structured inspection process like the one described in Device Giant’s phone inspection checklist shows how condition grading can double as the documentation your write-off file needs.
Pro Tip: Split your dead stock list in two: a markdown bucket for your better slow movers and a liquidation bucket for clear losers. Trying to rescue everything the same way wastes time on SKUs that were never coming back.
How to prevent dead stock: buying rules, forecasting, and SKU rationalization
Every write-off is a signal that a purchasing decision needs revisiting. A few habits keep the next round smaller.
- Order smaller test quantities for new SKUs before committing to full production runs.
- Set auto-reorder limits tied to actual sell-through, not last year’s forecast.
- Run a 20/80 analysis to identify the small set of SKUs driving most of your revenue, then set a review cadence for everything outside that group.
- Check sell-through weekly rather than monthly, so a stalling SKU gets flagged before it becomes a 90-day aging problem.
- Build reorder triggers and low-stock alerts directly into your inventory system instead of relying on manual review.
Our SKU rationalization framework walks through how to find that top 20% and protect it from the kind of over-ordering that eventually ends up on a write-off list. Pairing that with a SKU profitability analysis helps you decide, SKU by SKU, which items to keep, fix, or cut before they turn into dead stock.
Practitioner tips from Commerce Catalyst for faster cash recovery
The write-off workflow above matches the pattern we use with consumer brand founders working through a DTC turnaround: rationalize the SKU list first, apply targeted markdowns to the items worth saving, then liquidate the rest in a single coordinated push rather than piecemeal over months. Done this way, founders typically recover cash weeks faster than a case-by-case approach, because the decision criteria are set once instead of re-litigated SKU by SKU.
Some shortcuts in fast diagnostics include a one-page approval form that captures SKU evidence and recovery attempts in a single sign-off, a prioritized SKU list ranked by dollar exposure rather than unit count, and a short physical-count protocol that a warehouse team can complete in a single afternoon.
Why disciplined write-offs are a business advantage, not an admission
Delaying a write-off does not protect the business. It hides the real cause, whether that is a forecasting miss, a bad buy, or a SKU that should never have launched, and it keeps capital locked in something that will never sell. Clean, prompt write-offs free that cash and sharpen the next buying decision. A written policy that forces the question regularly, rather than once a year during an audit, is one of the more underrated disciplines a growing brand can adopt.
How Commerce Catalyst helps you turn write-offs into cash and cleaner books
A write-off should trigger a bigger conversation about why the inventory went dead in the first place, and that is where we come in. We work hands-on with consumer brand founders to turn a messy inventory situation into a prioritized action plan, not just a cleaner balance sheet.
- The DTC Operator Diagnostic pinpoints where cash is stuck, inventory included, and ranks the fixes by impact.
- The Financial Health Assessment reviews how write-offs are flowing through your statements and whether your documentation would hold up to scrutiny.
- The 90-Day Profit Sprint for Consumer Brands is built for founders who need a short-term cash recovery plan, including moving dead stock, executed on a timeline rather than discussed indefinitely.

FAQ
Can you write off dead stock?
Yes, dead stock can be written off when it has no remaining market value and you have documentation to support that conclusion, including a reconciled physical count and condition reports. Without that evidence, the IRS may challenge the deduction, as outlined in chief counsel guidance on inventory valuation.
How do you write off worthless inventory?
Quarantine the SKUs, perform a reconciled physical count, estimate net realizable value, and get written approval before posting the journal entry, typically a debit to inventory write-off expense or COGS and a credit to inventory. The NetSuite write-off guide walks through this entry pattern along with guidance on when a loss is material enough to warrant its own account.
Is dead stock still worth anything?
Sometimes. Items that failed in one channel can still recover partial value through markdowns, bundling, vendor returns, or liquidation, while others have genuinely dropped to zero and belong on a scrap or donation path, as described in Shopify’s inventory liquidation guide.
How do you clear dead stock quickly?
Split the list into a markdown bucket for SKUs that still have some brand value and a liquidation bucket for clear losers, then run both tracks at once instead of working through items one at a time. Keeping a weekly sell-through check and clear reorder triggers, as described in Shopify’s guide to avoiding dead stock, prevents the next batch from building up the same way.
