Money you get from selling scrap metal is taxable income, whether you run loads to the yard every week or drop off a single junked appliance once a year. Federal law defines gross income as “all income from whatever source derived,” and scrap proceeds fall inside that definition.1Office of the Law Revision Counsel. 26 U.S. Code 61 – Gross Income Defined What you actually owe depends on two things: your cost basis in the metal, and whether the IRS treats your selling as a business or a hobby.
Figuring What Portion Is Actually Taxable
You don’t owe tax on every dollar the yard hands you. The taxable amount is the sale price minus your basis in the material, meaning what the metal originally cost you. How you got hold of the scrap sets that basis.
For items you bought for personal use, like a broken lawnmower or a dead car, basis is what you originally paid. Sell an old water heater you bought for $600 as scrap for $30 and you took a loss, not a gain. If you can’t remember or prove what you paid, the IRS treats your basis as zero and the full sale amount is taxable.
For scrap you bought specifically to resell, basis is the purchase price plus direct costs like transportation, sorting, or processing.
One catch worth knowing up front: a loss on a personal-use item is not deductible.2Internal Revenue Service. Capital Gains, Losses, and Sale of Home You just absorb it. A business, by contrast, can deduct losses on inventory and business assets.
Inherited Items
If you inherited property and then sold it for scrap, your basis is generally the fair market value on the date the original owner died, not what they originally paid.3Internal Revenue Service. Gifts and Inheritances If your father’s old truck was worth $200 at his passing and you scrapped it for $500, your taxable gain is $300. If it was worth $2,000 and you scrapped it for $500, the loss is still not deductible when the item was personal-use.
Hobby or Business? The Classification That Changes Everything
The single biggest factor in how much tax you owe is whether the IRS views your scrap activity as a hobby or a business. The two paths lead to very different results for deductions, self-employment tax, and where the income lands on your return.
When It’s a Business
The IRS treats an activity as a business when your primary purpose is earning income and you pursue it with continuity and regularity. Regular buying of scrap, maintained equipment, tracked inventory, or meaningful hours each week point to a business. You report income and expenses on Schedule C (Form 1040).4Internal Revenue Service. About Schedule C (Form 1040), Profit or Loss from Business (Sole Proprietorship)
The upside is deductions. You can subtract ordinary and necessary expenses from gross receipts: vehicle mileage or actual fuel, equipment wear, trailer maintenance, the cost of scrap you bought to resell, tolls, repairs. The downside is that your net profit is hit twice, first by regular income tax and then by self-employment tax.
A useful shortcut on classification: if your scrap activity shows a profit in at least three of the most recent five years, the IRS presumes you’re in it for profit.5Internal Revenue Service. Form 5213 – Election To Postpone Determination as To Whether the Presumption Applies That an Activity Is Engaged in for Profit The presumption doesn’t insulate you from questions, but it shifts the burden to the IRS.
When It’s a Hobby
Selling leftover metal from a garage cleanout, or hauling a demolished fence to the yard as a one-off, looks like a hobby. The income is still taxable and gets reported on Schedule 1 (Form 1040), line 8j.6Taxpayer Advocate Service. Hobby vs. Business Income
The trade-off cuts both ways. Hobby expenses are not deductible, so travel, fuel, and processing costs don’t reduce what you report.7Internal Revenue Service. Know the Difference Between a Hobby and a Business But hobby income also isn’t subject to self-employment tax, saving up to 15.3% compared with business income.
Self-Employment Tax on Business Income
If you’re operating a business, the net profit on Schedule C flows to Schedule SE, where you calculate self-employment tax. This funds Social Security and Medicare and applies once net self-employment earnings hit $400.8Office of the Law Revision Counsel. 26 USC 1402 – Definitions
The rate is 12.4% for Social Security on net earnings up to the 2026 wage base of $184,500, plus 2.9% for Medicare on all net earnings with no cap.9Social Security Administration. What Is the Current Maximum Amount of Taxable Earnings for Social Security Combined, that’s the familiar 15.3%. Above $184,500, only the 2.9% Medicare portion continues.10Internal Revenue Service. Instructions for Schedule SE (Form 1040)
Two details that catch people off guard. SE tax is calculated on 92.35% of net earnings, not the full amount. And you can deduct half of the self-employment tax you pay as an adjustment to income on Form 1040, which trims your overall bill.11Internal Revenue Service. Schedule SE (Form 1040) – Self-Employment Tax
How to Report It on Your Return
You must report all scrap income regardless of the amount and regardless of whether the yard sends you any tax form.
Business filers put gross scrap revenue and all deductible expenses on Schedule C.4Internal Revenue Service. About Schedule C (Form 1040), Profit or Loss from Business (Sole Proprietorship) Net profit carries to Form 1040 at your ordinary income tax rate and to Schedule SE for self-employment tax.
Hobby filers report the gross income on Schedule 1 (Form 1040), line 8j.6Taxpayer Advocate Service. Hobby vs. Business Income No expenses come off, so the full amount adds to adjusted gross income, and only regular income tax applies.
The Higher 1099 Threshold Doesn’t Change What You Owe
Scrap yards that pay you above a certain threshold must send you and the IRS an information return, most commonly a Form 1099-NEC or in some cases a Form 1099-MISC. For payments made after December 31, 2025, that threshold rose from $600 to $2,000 per calendar year.12Internal Revenue Service. Form 1099-NEC and Independent Contractors Fewer sellers will get a 1099 in 2026 than in prior years.
Do not confuse the yard’s reporting obligation with yours. The $2,000 figure controls when the buyer must issue a form, not when you must report income. If you sell $800 worth of scrap across the year and never receive a 1099, you still owe tax on that $800 and must include it on your return. Yards track every payment they make in their own books, and the IRS can match those records to bank deposits.
Quarterly Estimated Payments for Business Sellers
Self-employment income has no automatic withholding. If you expect to owe $1,000 or more in federal tax for the year, you’re generally required to make quarterly estimated payments using Form 1040-ES.13Internal Revenue Service. Estimated Taxes Deadlines fall in April, June, September, and January of the following year. Miss one or underpay and you’ll owe an estimated tax penalty on the shortfall.
If you also work a W-2 job and your scrap income is on the hobby side, you can often skip quarterly filings by increasing your withholding at work to cover the extra tax. Adjusting your W-4 is simpler than sending in four separate payments.
Records That Protect Your Numbers
Good records are the difference between paying tax on your actual profit and paying tax on every dollar of gross receipts because you can’t prove your costs. For each sale, track the date, the type of metal, the weight, the price per unit, the total paid, and the buyer. Save every yard receipt.
On the expense side, keep receipts for fuel, equipment, repairs, tolls, and any scrap you purchased to resell. If you use a personal vehicle, keep a contemporaneous mileage log that separates business miles from personal driving. Standard mileage is the simplest method, but the log is what makes it stick.
The IRS generally expects you to keep tax records for at least three years from the date you filed.14Internal Revenue Service. Topic No. 305, Recordkeeping If you underreport gross income by more than 25%, the assessment window extends to six years, so holding records longer is a reasonable precaution. Many states also require yards to collect photo ID and vehicle information under anti-theft laws, and those records double as documentation for your own files.
Sales Tax Usually Isn’t Your Problem
Sales tax and income tax are separate obligations. When you sell scrap to a commercial yard, the transaction is typically treated as a sale for resale, because the yard is buying raw material it will process and sell downstream. The sales tax obligation, if any, lands on later transactions in the supply chain rather than on you. Rules vary by state, so if you’re selling in large quantities directly to end buyers rather than to a licensed dealer, check your state’s requirements.
What Skipping the Report Costs
Not reporting scrap income invites penalties that can dwarf the tax you would have paid. The IRS can impose an accuracy-related penalty of 20% on any underpayment tied to unreported income.15Office of the Law Revision Counsel. 26 U.S. Code 6662 – Imposition of Accuracy-Related Penalty on Underpayments Interest runs on the unpaid amount from the original due date until you settle.
Separate penalties apply for filing late (up to 25% of unpaid tax) and paying late (another 25%). If the IRS concludes the omission was deliberate, fraud penalties reach 75% of the underpayment.
Not receiving a 1099 is not a defense. Even with the higher $2,000 threshold, the IRS can match yard records, bank deposits, and other data to what you filed. Reporting relatively small amounts of scrap income voluntarily costs far less than answering an IRS notice two years later.
