Salvage value is the estimated dollar amount an asset will be worth at the end of its useful life. The term does real work in two very different places: tax depreciation, where it can reduce how much of an asset’s cost you write off each year, and insurance claims, where it reduces your payout if you keep a vehicle the insurer has declared a total loss. The rules diverge enough between those two settings that treating them as one concept leads to costly mistakes.
Salvage Value in Tax Depreciation
Federal tax law lets businesses deduct the cost of property that wears out over time. Under 26 U.S.C. § 167, property used in a trade or business qualifies for a “reasonable allowance” for exhaustion, wear, and obsolescence.1Office of the Law Revision Counsel. 26 U.S. Code 167 – Depreciation Under the traditional straight-line method, you subtract estimated salvage value from the purchase price before spreading the remainder across the asset’s useful life. That difference is the depreciable base.
A quick example. A $50,000 machine with a $5,000 salvage value and a 9-year useful life gives you a depreciable base of $45,000, or $5,000 per year in deductions. Set salvage too low and you inflate the annual deduction; set it too high and you leave deductible cost on the table.
For certain intangible property still depreciated under the straight-line method, the IRS instructs taxpayers to subtract salvage value from the adjusted basis to determine total allowable depreciation.2Internal Revenue Service. Publication 946 How To Depreciate Property If the useful life or adjusted basis changes significantly, the annual deduction may need to be recalculated.
Why MACRS Ignores Salvage Value
Most business owners can stop worrying about the estimate. The Modified Accelerated Cost Recovery System, which applies to nearly all tangible business property placed in service after 1986, treats salvage value as zero.3Office of the Law Revision Counsel. 26 USC 168 – Accelerated Cost Recovery System That is not a rounding convention. The statute says it directly: “Salvage value shall be treated as zero.” You depreciate the full cost of the asset without subtracting anything for what it might be worth later.
Under MACRS, property falls into recovery classes based on asset type rather than an individual useful-life estimate, so the salvage figure never enters the calculation. The traditional cost-minus-salvage math only surfaces for specific situations, like certain intangible property still depreciated under § 167.2Internal Revenue Service.

Section 179 and Bonus Depreciation
Two other provisions can remove depreciation schedules entirely. Section 179 lets qualifying businesses deduct the full purchase price of eligible equipment and software in the year it is placed in service, up to $2,560,000 for 2026. That deduction begins phasing out when total qualifying purchases exceed $4,090,000.
Bonus depreciation, made permanent at 100% for qualifying property acquired after January 19, 2025, under the One Big Beautiful Bill, allows businesses to write off the entire cost of eligible assets in the first year.4Internal Revenue Service. Treasury, IRS Issue Guidance on the Additional First Year Depreciation Deduction Amended as Part of the One Big Beautiful Bill When either provision applies, salvage value is irrelevant to the tax calculation because nothing remains to depreciate over time.
So salvage value matters most for tax purposes when you are depreciating intangible property under the straight-line method, or when you have elected out of MACRS for a particular asset. For most tangible equipment, vehicles, and machinery a business buys today, the tax code either ignores salvage value or lets you deduct the full cost upfront.
Recapture When You Sell a Depreciated Asset
Salvage value does not disappear just because the tax code let you ignore it during depreciation. When you sell, scrap, or trade in a business asset, the IRS wants its share of any gain, and the math surprises people who depreciated the full cost to zero.
Under 26 U.S.C. § 1245, if you sell depreciable personal property for more than its adjusted basis (original cost minus depreciation taken), the gain is taxed as ordinary income to the extent of prior depreciation deductions.5Office of the Law Revision Counsel. 26 U.S. Code 1245 – Gain From Dispositions of Certain Depreciable Property This is depreciation recapture, and it applies whether the asset was depreciated under MACRS, Section 179, or bonus depreciation.
Say you bought a $50,000 machine, depreciated it entirely to zero, then sold it for $8,000. That $8,000 is ordinary income because it falls within the amount you previously deducted. You got the tax benefit on the way down; the IRS takes some back on the way up. Only gain above the total depreciation taken would qualify for the lower capital gains rate. Salvage value shows up here in practice even when the depreciation system pretended it did not exist.
Salvage Value in a Total Loss Insurance Claim
In insurance, salvage value means something more immediate: what the wrecked or severely damaged vehicle is worth as-is, typically based on what a salvage yard or auction buyer would pay for it. Insurers use this figure when settling total loss claims.
A vehicle is declared a total loss when repair costs reach a set percentage of its actual cash value. That threshold varies by state, ranging from 60% to 100%. Most states use 75%; several use 70% or 80%; a few use a formula rather than a flat percentage. Your state’s threshold decides the tipping point, and a car that would be repaired in one state might be totaled in another.
Once a vehicle is totaled, the insurer determines its actual cash value (what it was worth immediately before the accident) and its salvage value (what the wreckage would bring at auction). If you accept the full payout, you hand the vehicle over and the insurer sells it to a salvage buyer to offset costs. Your settlement equals actual cash value minus your deductible.
Keeping a Totaled Vehicle
You can usually keep the totaled vehicle instead of surrendering it. When you do, the insurer subtracts the salvage value from your payout, because you are keeping the asset it would otherwise have sold:
Actual Cash Value − Salvage Value − Deductible = Your Settlement
You walk away with both a reduced check and the damaged car. Whether that makes sense depends on what you plan to do with it. If the damage is cosmetic and the car drives safely, keeping it and pocketing a smaller settlement can work. If the frame is bent or airbags deployed, repair costs can easily exceed what you kept by retaining it.
Retention also triggers a title brand. The vehicle receives a salvage title, which signals to future buyers and insurers that the car sustained damage exceeding its economic value at the time of the loss. Before a salvage-titled vehicle can return to the road, most states require repairs and a safety inspection, after which the title is rebranded as “rebuilt.” Inspection requirements, documentation, and fees vary by state.
Even with a rebuilt title, the vehicle carries a permanent stigma. Not all insurers will offer full coverage on a rebuilt-title car, and those that do may limit you to liability and exclude collision or comprehensive protection. Premiums also tend to run higher, because insurers view prior structural damage as an ongoing risk factor. Check with your carrier before committing to keep the vehicle.
Disputing the Insurer’s Number
Insurance companies determine salvage value using internal formulas, software tools, valuation databases, and past auction results for similar vehicles. These methods are not standardized across the industry, so two insurers can look at the same wreck and arrive at different figures. The actual cash value assigned to the pre-accident vehicle can also shift based on which comparable sales the adjuster selects.
If the offer seems low, most auto policies include an appraisal clause. You hire an independent appraiser, the insurer does the same, and if the two cannot agree, they select an impartial umpire whose determination is binding. The appraisal clause generally applies only to first-party claims filed under your own policy, not to claims against another driver’s insurer.
Before invoking it, gather your own evidence: recent sale prices for comparable vehicles in your area, documentation of upgrades or recent maintenance, and mileage records. An independent appraiser typically costs a few hundred dollars, so the process makes sense when the gap between the insurer’s offer and your expected value is large.
How the Estimate Gets Built
Salvage value is always an estimate, and the inputs differ by context.
For business assets, the estimate draws on historical resale data for similar equipment, expected end-of-life condition, and prevailing scrap prices for the materials involved. A steel-heavy industrial machine tracks commodity prices differently than an electronic system whose components become obsolete. Businesses that operate vehicle fleets can use their own disposal history to project reasonably accurate figures.
For insurance, appraisers focus on what the damaged item would bring at a salvage auction. Key factors include current demand for the vehicle’s reusable parts (engines, transmissions, and electronics from popular models command higher prices), the weight of the vehicle relative to current scrap metal rates, and the cost of disposing of hazardous materials like fluids and batteries. A wrecked late-model SUV with a functioning drivetrain will have a far higher salvage value than a 20-year-old sedan with frame damage, even if they weigh the same.
Scrap metal rates themselves fluctuate with global commodities markets, so the same vehicle can carry a meaningfully different salvage value depending on when the loss occurred. Environmental disposal costs also reduce the net recovery, particularly for older vehicles with components that require special handling.
