To start an estate sale business, you form a legal entity (an LLC in most cases), register for the licenses your state and city require, get a sales tax permit, put liability insurance in place, and draft a client contract that spells out your authority, commission, and payout terms. The work itself is straightforward once those pieces are in place. What trips up new operators is not the selling. It’s the licensing rules that treat estate sales like auctions, the inventory categories that carry federal restrictions, and the tax obligations that come due long before April.
Set Up the Business Entity
A Limited Liability Company is the standard choice. An LLC keeps your personal assets separate from the business, which matters the first time a shopper trips on a rug or a client accuses you of losing an heirloom. State filing fees range from $45 in Arkansas to $520 in Massachusetts, with most states between $50 and $200.1Wolters Kluwer. State Business Formation and Filing Fees
After the LLC is formed, apply for a federal Employer Identification Number through the IRS. The EIN is your business’s tax ID and is required to open a business bank account, file employment taxes, and report income. Applying online through the IRS portal is free and takes minutes.2Internal Revenue Service. Get an Employer Identification Number
Get the Right Licenses
Estate sale companies sit in an awkward regulatory gap. You’re selling other people’s property for a commission, which many state licensing boards read as auctioneering. Roughly half of all states require an auctioneer license to conduct estate sales, and the education, bonding, and fee requirements vary widely. Skipping this step is the most common legal mistake new operators make, and it can produce fines or a cease-and-desist order mid-sale. Check with your state’s licensing board before you book a first client.
Beyond the auctioneer question, most jurisdictions require a general business license or permit. Some cities and counties add a secondhand dealer registration, particularly for businesses that handle jewelry, electronics, or antiques. Budget roughly $25 to $150 for local permits, and expect to renew them annually.
You also need a sales tax permit from your state’s department of revenue. Estate sales move tangible goods, and you are responsible for collecting and remitting the tax on every transaction. Rates run from under 5% in some states to over 10% in parts of California.3California Department of Tax and Fee Administration. California City and County Sales and Use Tax Rates A handful of states have no sales tax. Register before your first sale; collecting tax without a permit creates its own problems.
Insure the Work
General liability insurance covers the physical risks of opening a private home to the public. Small service businesses typically pay $500 to $2,000 per year, depending on limits and claims history.
Professional liability insurance, sometimes called errors and omissions coverage, is the one people forget. If you price a rare painting at $200 and it turns out to be worth $20,000, the client’s claim comes after this policy rather than your personal savings. Estate work involves routine judgment calls on items you may not be an expert in, which is exactly the exposure E&O is built for.
Some jurisdictions require a surety bond before issuing your business or auctioneer license. The bond guarantees your clients: if you fail to remit sale proceeds, the bonding company pays the client and then pursues you. Premiums typically run 1% to 4% of the bond amount for applicants with good credit, so a $10,000 bond might cost $100 to $400 a year.
Write a Client Contract That Holds Up
The client agreement is the single most important document in the business. It defines who you are, what you’re doing on the client’s behalf, and how you get paid. Every contract should cover at least the following:
- Legal authority to sell. Confirm the client has the right to sell the property. For estates where someone has died, this usually means letters testamentary from a probate court, which formally authorize the executor to manage and distribute assets. For divorces or relocations, the homeowner or their authorized representative signs.
- Commission rate. Estate sale commissions typically fall between 25% and 45% of gross sales. The rate varies with the estimated value of the estate, the amount of prep work, and local competition. Smaller estates often carry a higher percentage because the fixed labor costs don’t shrink with the inventory.
- Unsold items. Say in writing who removes what’s left when the sale ends. Many contracts let the liquidator donate leftovers to charity, but the client has to approve that in advance.
- Payment timeline. Most liquidators pay out within 10 to 21 days after the sale, net of commissions, advertising, and other agreed expenses. The contract should require a written closing statement showing gross sales, itemized deductions, and the net amount owed.
Templates from legal document providers are a reasonable starting point. The specifics matter more than the template. Vague language around commission calculations or unsold-item responsibility is where client disputes start.
Know What You Cannot Sell
Certain items that show up regularly in estates carry legal restrictions. Understanding these before you agree to a sale is part of the job.
Firearms
Firearms rules depend on how the sale is structured. Under federal law, an estate sale company acting as an agent of the estate does not need a Federal Firearms License, because the firearms stay under the estate’s control and the sale is made on the estate’s behalf.4ATF. Do I Need a License to Buy and Sell Firearms The distinction is between estate-type and consignment-type sales. If you take possession of the firearms, inventory them, and resell them on your own schedule, the ATF treats that as a consignment arrangement, and you would need a dealer license.5Office of the Law Revision Counsel. 18 US Code 923 – Licensing State laws add more. Some states require background checks on private-party firearm sales regardless of the estate context. Check federal and state rules before including any firearm in a sale.
Ivory and Endangered Species Products
A near-total federal ban on commercial trade in African elephant ivory has been in effect since 2016. You cannot sell ivory items across state lines unless the piece qualifies as an antique, meaning it is at least 100 years old, has not been repaired with ivory after December 1973, and you can document those facts.6U.S. Fish & Wildlife Service. Guidance for Trade in Elephant Ivory Intrastate sales may be allowed if the ivory was lawfully imported before 1990, but several states have their own bans that go further than federal law. When in doubt, pull the item. The burden of proof is on the seller and the fines are substantial.
Hazardous Household Materials
Old paint, cleaning chemicals, pesticides, pool supplies, and automotive fluids are not saleable. The EPA classifies them as household hazardous waste.7US EPA. Household Hazardous Waste (HHW) Even where the strictest federal disposal rules don’t apply, state and local rules usually do, and putting these items in front of the public creates obvious liability. Direct the client to their local hazardous waste collection program.
Handle Help Legally
Even a small sale needs two or three people for setup, checkout, and security. The legal question is whether those helpers are employees or independent contractors. The IRS treats the two very differently.
The IRS weighs three categories of evidence: whether you control how the work is done (behavioral control), whether you control the financial side like payment method and expense reimbursement (financial control), and the nature of the relationship, including benefits and any written contract.8Internal Revenue Service. Independent Contractor (Self-Employed) or Employee? No single factor decides the question, but estate sale workers are hard to defend as independent contractors when you tell them where to stand, when to arrive, and how to process transactions. Misclassification exposes you to back taxes, penalties, and interest.
Hire employees and you’ll need workers’ compensation insurance in nearly every state, usually the moment you have one employee. You’ll also need to withhold income tax, Social Security, and Medicare, and file the payroll tax returns. Payroll software handles most of this for a modest monthly fee.
Plan for Your Own Taxes
New operators focus on sales tax and forget their own income taxes until April. As a self-employed owner, you owe income tax and self-employment tax on your net earnings. Self-employment tax runs 15.3%, covering the Social Security and Medicare contributions that an employer would otherwise split with you.
The IRS expects self-employed taxpayers to pay quarterly, using Form 1040-ES, rather than waiting for the annual filing. If you expect to owe $1,000 or more for the year, you’re generally required to make these payments. Missing the deadlines triggers an underpayment penalty. You can avoid the penalty by paying at least 90% of the current year’s tax liability or 100% of the prior year’s tax through the quarterly installments.9Internal Revenue Service. Estimated Taxes
If you accept card payments through a processor like Square, know the 1099-K threshold. Processors must report your gross payments to the IRS when they exceed $20,000 and 200 transactions in a calendar year.10Internal Revenue Service.
