Tax Rules for Renting and Selling in the US: A BorrowSphere Guide

Renting out a pressure washer or selling a used bike through BorrowSphere can produce taxable income in the US. This guide covers which IRS forms apply, when a side activity becomes a business, how state and local taxes layer on top, and which records to keep.

Three Layers of Tax

  • Federal — the IRS collects income and self-employment tax.
  • State — each state sets its own income tax and sales and use tax; a few impose neither.
  • Local — counties and cities often add sales tax, and some levy income tax.

There is no national VAT and no federal sales tax: consumption taxes are purely state and local, so the same transaction can be taxed differently in two nearby towns.

For individuals the tax year is the calendar year, and the return is generally due April 15 of the following year; an extension buys time to file, not to pay.

All Income Is Reportable

US law requires you to report income from all sources unless specifically excluded — occasional rental fees, one-off resale profits, and cash payments with no paperwork. A tax form is only a copy of information also sent to the IRS; its absence is no permission to omit income.

Form 1099-K

Payment settlement entities and many marketplaces issue Form 1099-K reporting gross payments processed for you during the year:

  • The threshold has changed repeatedly. Congress and the IRS have revised and delayed the 1099-K dollar and transaction thresholds several times in recent years, and some states set lower ones. Check the current number on IRS.gov rather than trusting a figure you read last year.
  • 1099-K reports gross payments, not profit. The total includes platform fees, shipping, refunds, and chargebacks, so your return must reconcile it against actual basis and expenses.

Receiving no 1099-K changes nothing about your obligation to report.

Selling Used Items: Gain, Loss, and Basis

  • Sold for less than you paid. No taxable gain — and a loss on personal-use property is not deductible. The $600 lost on a used treadmill cannot offset other income.
  • Sold for more than you paid. The difference is a capital gain, reported on Form 8949 and summarized on Schedule D — mostly collectibles and vintage gear.

Your basis is what you originally paid plus improvements. Holding period sets the rate: one year or less is a short-term gain taxed at ordinary rates, longer is a long-term gain at preferential rates. Keep the original receipt — without proof of basis, the IRS can treat the entire sale price as gain.

Renting Out Property: Which Schedule Applies

This is where most users go wrong, and where common outdated advice needs correcting: casual rental income is not "miscellaneous income" on the face of Form 1040.

  • Casual rental of personal property — tools, cameras, bikes — that is not a trade or business goes on Schedule 1 (Form 1040), with related expenses deducted there and capped at the rental income, so they cannot offset your salary.
  • A regular, profit-seeking rental operation is a trade or business, reported on Schedule C, with net earnings flowing to Schedule SE for self-employment tax of about 15.3%, generally owed once net earnings reach $400.
  • Schedule E is for real estate and royalties, not for renting out a chainsaw or a drone — using it for equipment rental is a frequent, avoidable error.

Hobby or Business?

The IRS weighs profit motive, regularity, and whether you keep businesslike records and separate accounts. The consequences are asymmetric: hobby income is still fully reportable, but hobby expenses are generally not deductible.

Deductions for Business Sellers

On Schedule C, ordinary and necessary expenses are deductible:

  • Repairs, maintenance, cleaning, and consumables
  • Insurance on the equipment or activity
  • Storage space and protective cases
  • Listing fees, platform commissions, and advertising
  • Mileage for drop-offs and pickups, at the standard rate or actual costs

Equipment lasting beyond a year is recovered through depreciation. Section 179 expensing and bonus depreciation allow a large or complete write-off in the year an asset is placed in service, subject to annual limits, while the de minimis safe harbor expenses low-cost purchases immediately. Confirm the current limits for your filing year.

Sales and Use Tax

Sales tax is set by states and usually counties and cities on top, with combined rates from zero to roughly 10% or more. Five states have none statewide: Alaska (local sales taxes still permitted), Delaware, Montana, New Hampshire, and Oregon.

  • In many states, renting out tangible personal property is itself a taxable transaction. The rental charge is treated much like a sale, so tax may apply even though ownership never changes hands.
  • Marketplace facilitator laws shift collection and remittance to many platforms, but coverage varies by state and does not always cover rentals — confirm who is responsible rather than assuming.

Use tax is the mirror image: buy something taxable with no sales tax charged, and your state generally expects the equivalent from you.

State and Local Income Tax

Eight states impose no broad individual income tax: Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming. Elsewhere your federal figures flow into a state return with its own rates, and some cities add a layer — New York City taxes residents on top of New York State.

Sellers working across state lines should understand nexus: storing inventory or exceeding activity thresholds in another state can require registering and filing there, with separate rules for income and sales tax.

Quarterly Estimated Payments

Rental and resale income arrives without withholding, so tax on it is prepaid during the year on Form 1040-ES, due in April, June, September, and the following January. Underpaying triggers a penalty even if you settle in full by April 15, so aim for a safe harbor: paying in at least the required percentage of this year's tax or last year's total. Setting aside a fixed share of each payout is the simplest way there.

Administrative Basics

  • EIN — an Employer Identification Number is free from the IRS and spares you handing out your Social Security number.
  • Form W-9 — platforms and business customers use it to collect your taxpayer ID number.
  • Backup withholding — with no valid TIN on file, the payer must withhold part of your payments; an accurate W-9 avoids it.

Recordkeeping

  1. Purchase receipts establishing basis for each item you rent out or resell
  2. Invoices and rental agreements with dates, amounts, and parties
  3. Platform payout and fee statements, downloaded before year-end
  4. Repair, cleaning, insurance, and storage receipts
  5. A mileage log with date, destination, purpose, and miles
  6. Copies of any 1099-K or other information returns

The IRS generally recommends keeping records at least three years from the filing date, and basis records as long as you own the property.

Sustainability and "Green" Tax Breaks

Reuse and local renting keep usable goods out of landfills and cut what households spend on equipment used a few times a year. But there is no general federal credit or deduction for renting rather than buying, or reselling rather than discarding: the payoff is cost savings, not a tax break.

One real deduction sits nearby: donating usable goods to a qualified 501(c)(3) is deductible at fair market value if you itemize instead of taking the standard deduction. Keep a written acknowledgment, and file Form 8283 for larger noncash donations.

Summary

Income earned renting or selling through BorrowSphere is reportable whether or not a 1099-K arrives, and the gross figure on that form is a starting point, not your taxable amount. Selling at a loss yields nothing to report and no deductible loss; selling at a gain means Form 8949 and Schedule D. Casual equipment rental goes on Schedule 1, a real rental business on Schedule C with self-employment tax on Schedule SE, and Schedule E is reserved for real estate and royalties. On top sit state and local income tax, sales and use tax that often applies to rentals, quarterly payments on Form 1040-ES, and records kept at least three years.
