What Is a Direct Seller? Section 3508 Rules and Tax Deductions

A direct seller is someone who sells consumer products to buyers away from a permanent retail store and who qualifies, under Internal Revenue Code Section 3508, as a “statutory non-employee” for federal tax purposes. The classification depends on three conditions being met at once: the sales happen somewhere other than a fixed storefront, pay is tied to sales output rather than hours worked, and a written contract states the seller will not be treated as an employee for federal tax purposes.¹ Meeting the test changes how you’re paid, how you’re taxed, and what consumer-protection duties you owe your buyers.

The Three Requirements Under Section 3508

Section 3508 is a precise legal label, not a general description. Fail any one of its three prongs and you may be reclassified as an employee, which flips your entire tax picture.

Sales Away From a Permanent Retail Establishment

The statute describes qualifying sales as taking place “in the home or otherwise than in a permanent retail establishment.”¹ A customer’s living room qualifies. So does your dining table during a product party, a hotel conference room, an office break room, or a temporary booth at a fair. The thread running through all of it is mobility: you bring the product to the buyer rather than staffing a fixed store.

Pay Tied to Sales, Not Hours

“Substantially all” of a direct seller’s compensation must relate to sales or services delivered, not hours worked.¹ Commissions, performance bonuses, and overrides on team sales all fit. An hourly wage or fixed salary does not, no matter how much the rest of the arrangement looks like direct selling. The structure means you carry real financial risk: a slow month can mean little or no income, with no guaranteed minimum.

A Written Non-Employee Contract

You and the company must have a written contract that says, in so many words, you will not be treated as an employee for federal tax purposes.¹ Because the statute requires services to be “performed pursuant to” the contract, the agreement needs to be in place before you start selling, not signed after the fact. Without that language, the classification collapses; the company could owe back payroll taxes, and you could lose access to self-employment deductions. Keep a copy for your records. If the IRS ever questions the arrangement, that contract is the primary evidence.

How a Direct Seller Is Taxed

Once the three requirements are met, Section 3508 treats you as self-employed for every federal tax purpose. The company doesn’t withhold income tax or FICA from your checks. The whole tax bill is yours.¹

Self-Employment Tax

The self-employment tax rate is 15.3%: 12.4% for Social Security and 2.9% for Medicare.² An employer would normally pay half; a direct seller pays both halves. The Social Security portion applies only up to $184,500 in net self-employment earnings for 2026, and the Medicare portion has no cap.³ Net self-employment income above $200,000 (or $250,000 for joint filers) picks up an additional 0.9% Medicare surtax on the excess.

You can deduct half of your self-employment tax as an above-the-line adjustment to income, which lowers your adjusted gross income even if you don’t itemize.⁴

Forms and Estimated Payments

Direct selling income and expenses go on Schedule C (Form 1040), the same form sole proprietors use.⁵ If you earn $2,000 or more from a single company during the year, that company must send you a Form 1099-NEC. This threshold rose from $600 to $2,000 for tax years beginning after 2025.⁶ Falling under the threshold doesn’t erase the tax. Every dollar of net profit is reportable whether or not you receive a 1099.

Because nothing is withheld from your commissions, you’re expected to make estimated tax payments four times a year: April 15, June 15, and September 15 of the tax year, and January 15 of the following year.⁷ Miss them and underpayment penalties can follow. New direct sellers used to W-2 withholding often get caught out by this in their first year.

Deductions Direct Sellers Can Claim

Self-employment costs more in tax, but it opens up write-offs W-2 employees can’t reach.

Vehicle Mileage

Driving to customer appointments, product demonstrations, and inventory pickups is deductible. The IRS standard mileage rate for business use is 72.5 cents per mile for 2026.⁸ If you own the vehicle and want to use this method, you must pick it in the first year the vehicle is available for business. For a leased vehicle, you have to stay with the standard rate for the whole lease. The alternative is tracking actual expenses like gas, insurance, and depreciation.

Home Office

A dedicated space in your home used regularly and exclusively for the business qualifies for the home office deduction. One rule matters especially for direct sellers: if your home is the only fixed location of your business and you store inventory or product samples there, the exclusive-use requirement is relaxed.⁹ That helps if you keep products in a spare bedroom that also serves another purpose.

The simplified method allows $5 per square foot of dedicated space, up to 300 square feet, for a maximum $1,500 deduction.¹⁰ The regular method uses actual home expenses proportional to business-use percentage and can produce a larger deduction if your costs are high, at the price of more recordkeeping.

Everyday Business Costs

Product samples, demonstration supplies, marketing materials, business phone expenses, and shipping costs are ordinary business expenses on Schedule C. Travel and lodging for company training events also count. Keep receipts. The IRS expects self-employed filers to substantiate deductions, and undocumented write-offs don’t survive an audit.

The FTC Cooling-Off Rule

Selling away from a store carries a specific federal consumer-protection duty. Under the FTC’s Cooling-Off Rule, a door-to-door sale of more than $25 gives the buyer three business days to cancel for any reason, with no penalty.¹¹ A business day means any calendar day except Sundays and federal holidays.

At the time of sale, you must give the buyer:

A dated contract or receipt showing your name and address and explaining the right to cancel, written in the same language used during the sales presentation.
Two copies of a cancellation form, so the buyer can keep one and mail the other back if they change their mind.¹²

Failing to provide those notices is itself a violation. If a buyer cancels within the three-day window, you must refund payment within 10 business days. Some states add their own cooling-off protections that extend the cancellation period or lower the dollar threshold.

Direct Selling Versus a Pyramid Scheme

Legitimate direct selling pays participants for selling products to real customers. A pyramid scheme pays participants primarily for recruiting new participants. The FTC’s test comes from its Koscot decision: a business crosses into pyramid territory when participants receive rewards unrelated to the sale of products to actual end users.¹³ There is no fixed percentage threshold. Regulators look at how the business actually operates, not what its policies say on paper. Common warning signs:

Compensation that requires recruiting a set number of people, or building multiple levels of recruits, before meaningful payouts kick in.
Large mandatory inventory purchases meant to qualify for bonuses rather than to resell to customers.
Training and recruiting pitches focused on income from building a “downline” rather than on the product itself.

An MLM can still qualify as a pyramid scheme even if it sells real products. Where the plan rewards recruiting over retail sales, and rank-and-file participants lose money while a small number at the top profit, the FTC can bring enforcement action.¹³ Before signing on, look at whether participants actually earn money selling to customers who aren’t also participants.

Inventory Buyback and Sales Tax

Two practical points sit outside the tax code but matter early. On inventory: the Direct Selling Association, the industry trade group, requires its member companies to repurchase marketable inventory from departing sellers at no less than 90% of the original net cost within 12 months of purchase. That’s an industry code, not federal law, so it only applies when the company is a DSA member. Several states have enacted their own repurchase laws, typically at 90% of cost for resalable products. Before investing heavily in stock, confirm the company has a written return policy and check the conditions.

On sales tax: your federal classification as a non-employee doesn’t settle who collects state sales tax. In some arrangements the company collects and remits as a marketplace facilitator; in others the direct seller registers with the state and handles collection personally. Where you’re responsible, you generally must collect tax in any state where you or the company has sales tax nexus. Unpaid sales tax becomes personal liability. Ask the company’s compliance department which model applies, and verify with your state’s department of revenue.
