The choice between a sole proprietorship, LLC, or S-corp affects how collectibles business income is taxed, how expenses are deducted, and whether self-employment tax applies. The IRC does not require any specific entity type — the tax treatment depends on how the entity elects to be classified.
- Sole proprietors and single-member LLCs are taxed identically on Schedule C by default
- LLCs provide liability protection but do not change federal tax treatment unless an election is made
- S-corp election (Form 2553) can reduce SE tax for dealers with sufficient net income through the salary/distribution split
- QBI deduction (§199A) is available to sole props and pass-throughs — collectibles dealing is NOT a specified service trade or business (SSTB)

Collectors who buy and sell collectibles as a trade or business face a question that casual sellers do not: what entity structure to use. The choice affects federal income tax, self-employment tax, state taxes, liability exposure, and administrative complexity. This article covers the federal tax treatment of each common entity type used by collectibles dealers — sole proprietorship, single-member LLC, multi-member LLC, and S-corporation — with worked examples showing how the numbers differ. It also covers the qualified business income deduction under IRC §199A, state formation considerations, and annual compliance requirements.
This article applies to collectors whose activity rises to the level of a trade or business (i.e., “dealers” under tax law). For the distinction between hobby, investor, and dealer status, see our Dealer vs Investor vs Hobbyist guide.
When Does a Collector Need an Entity?
The IRS does not require a specific entity type to operate a business. A sole proprietorship — with no formal entity — is a valid and common business structure. The question is whether an entity provides benefits that justify the additional cost and administrative burden.
Volume and regularity. Collectors whose buying and selling activity constitutes a trade or business (frequent, regular, and continuous activity with the primary purpose of profit) are operating a business whether or not they form an entity. Revenue is reported on Schedule C (or the applicable entity return) regardless of entity structure. The entity choice affects how income is taxed, not whether it is taxed.
Liability. A sole proprietorship offers no separation between business and personal assets. If a buyer sues over a transaction dispute, or if a business creditor seeks payment, the sole proprietor’s personal assets (home, bank accounts, personal investments) are exposed. An LLC or corporation creates a separate legal entity, and if properly maintained, limits liability to the assets of the entity. This is a state law concept, not a tax concept.
Co-ownership. When two or more people operate a collectibles business together, they are treated as a partnership for federal tax purposes by default under IRC §7701. Forming a multi-member LLC provides a formal operating agreement, defines profit/loss allocation, and establishes each member’s rights and obligations.
Estate planning. An LLC can facilitate the transfer of a business interest to heirs through membership interest transfers. This is a legal and estate planning consideration, not a tax filing consideration.
Sole Proprietorship (Schedule C)
A sole proprietorship is the default classification for an individual operating a business. No state filing is required to create a sole proprietorship (though a local business license or DBA registration may be required). No separate federal tax return is filed — all business income and expenses are reported on Schedule C of the owner’s individual Form 1040.
Income tax. Net profit from Schedule C flows to Form 1040 and is taxed at the owner’s individual marginal tax rate. For a collectibles dealer, the income is ordinary business income, not capital gains — because items held for sale to customers are inventory, not capital assets, under IRC §1221(a)(1). This means the 28% collectibles capital gains rate does not apply to dealer income. Instead, the income is taxed at ordinary rates (10%, 12%, 22%, 24%, 32%, 35%, or 37%).
Self-employment tax. Net Schedule C profit is subject to self-employment (SE) tax under IRC §1402. The SE tax rate is 15.3% (12.4% Social Security + 2.9% Medicare) on net SE income up to the Social Security wage base ($176,100 for 2026). Above the wage base, only the 2.9% Medicare tax applies, plus the 0.9% Additional Medicare Tax on combined wages and SE income exceeding $200,000 (single) or $250,000 (married filing jointly). One-half of the SE tax is deductible as an above-the-line deduction on Form 1040 under IRC §164(f).
Deductions. All ordinary and necessary business expenses are deductible on Schedule C under IRC §162. For collectibles dealers, this includes cost of goods sold (inventory), shipping, packaging, platform fees, booth rental at card shows, travel to shows and auctions, supplies, insurance, and home office expenses (if applicable). No entity formation is required to claim these deductions.
EIN. A sole proprietor without employees can use their Social Security Number as their taxpayer identification number. However, an Employer Identification Number (EIN) can be obtained free from the IRS and used on Form W-9 when platforms or buyers request a taxpayer ID. This provides a separate identification number for business use.
Single-Member LLC
A single-member LLC (SMLLC) is formed under state law by filing articles of organization with the state. For federal tax purposes, a single-member LLC is a “disregarded entity” by default under Treas. Reg. §301.7701-3. This means the IRS ignores the LLC for income tax purposes — it is treated as if the owner operates the business directly.
Federal tax treatment. Identical to a sole proprietorship. All income and expenses are reported on Schedule C. Self-employment tax applies to net profit. The same deductions are available. There is no difference in federal income tax between a sole proprietorship and a single-member LLC (absent an election).
State-level protection. The LLC provides a liability shield under state law. Business debts and liabilities are generally limited to the LLC’s assets, protecting the owner’s personal assets. This protection requires maintaining the LLC as a separate entity: keeping business and personal finances separate, maintaining adequate capitalization, and following state-required formalities. If the LLC is not properly maintained, a court may “pierce the veil” and hold the owner personally liable.
State filing fees and franchise taxes. Every state charges a filing fee to form an LLC, typically $50 to $500. Many states also charge an annual report fee or franchise tax. California charges an $800 annual franchise tax minimum for all LLCs, regardless of income. Other states with notable annual fees include Illinois ($75 annual report), Massachusetts ($500 annual report), and New York (publication requirement that can cost $300–$1,500 depending on county). These costs are deductible business expenses but represent an additional cost not incurred by a sole proprietorship.
Election options. A single-member LLC can elect to be taxed as a corporation by filing Form 8832 (Entity Classification Election). It can further elect S-corporation status by filing Form 2553. These elections change the federal tax treatment of the LLC without changing its legal structure at the state level.
Multi-Member LLC
When two or more people form an LLC together, the default federal tax classification is a partnership under IRC §7701 and Treas. Reg. §301.7701-3. The LLC files a partnership return on Form 1065 and issues a Schedule K-1 to each member reporting their share of income, deductions, and credits.
Pass-through taxation. The LLC itself does not pay income tax. Instead, each member reports their distributive share of the LLC’s income on their individual tax return. The allocation of income and losses among members is determined by the operating agreement, subject to the substantial economic effect rules of IRC §704(b).
Self-employment tax. General partners (which includes all members of a member-managed LLC) are subject to SE tax on their distributive share of partnership income under IRC §1402(a). The SE tax treatment of limited partners and limited LLC members is a complex area with ongoing IRS guidance. For most multi-member LLCs operating a collectibles business where all members are active in the business, the distributive share is subject to SE tax.
Operating agreement. A multi-member LLC is governed by its operating agreement, which is a contract among the members. The operating agreement defines capital contributions, profit and loss allocations, management authority, voting rights, distribution rules, transfer restrictions, and dissolution procedures. While not required in all states, an operating agreement is essential for any multi-member LLC to define the members’ economic and governance rights.
Filing requirements. Form 1065 is due by March 15 of the following year (for calendar-year LLCs). Late filing penalties are $235 per member per month (2026 rate) under IRC §6698. Schedule K-1 must be furnished to each member by the Form 1065 due date.
S-Corp Election (Form 2553)
An LLC (single-member or multi-member) or a corporation can elect to be treated as an S-corporation for federal tax purposes by filing Form 2553 (Election by a Small Business Corporation). The S-corp election changes how the business income is allocated between salary and distributions, which affects self-employment tax.
How it works. An S-corp is a pass-through entity — it does not pay federal income tax at the entity level (with limited exceptions). Net income passes through to the shareholder(s) on Schedule K-1. The key difference from a sole proprietorship or default LLC is the treatment of self-employment tax. An S-corp shareholder who works in the business is treated as an employee. The shareholder-employee receives a W-2 salary, and FICA taxes (7.65% employee share + 7.65% employer share = 15.3% total) apply only to the salary. Distributions in excess of the salary are not subject to FICA or SE tax.
Reasonable compensation requirement. The IRS requires that S-corp shareholder-employees receive “reasonable compensation” for the services they perform. The compensation must be comparable to what the business would pay an unrelated employee for similar work. Setting the salary unreasonably low to avoid FICA tax is a well-known audit trigger. The IRS and courts have recharacterized distributions as wages when the salary was found to be unreasonably low (see Watson v. United States, 668 F.3d 1008 (8th Cir. 2012)).
Worked Example: Sole Prop vs S-Corp — SE Tax Comparison
Collectibles dealer with $150,000 gross revenue, $90,000 COGS and expenses, $60,000 net profit.
| As sole proprietorship: | |
| Net SE income ($60,000 × 92.35%) | $55,410 |
| SE tax ($55,410 × 15.3%) | $8,478 |
| As S-corp with $40,000 salary: | |
| FICA on $40,000 salary (15.3% combined) | $6,120 |
| Distribution ($60,000 − $40,000) | $20,000 |
| FICA on distribution | $0 |
| SE/FICA tax difference | ~$2,358 |
The S-corp structure shifts $20,000 from SE-taxable income to distribution income. The FICA savings of approximately $2,358 must be weighed against S-corp compliance costs: payroll processing, quarterly 941 filings, W-2 issuance, and potentially higher accounting fees. Both structures produce the same income tax — the savings are limited to FICA/SE tax.
Filing requirements. An S-corp files Form 1120-S annually, due by March 15 for calendar-year entities. The shareholder receives Schedule K-1. The S-corp must process payroll (quarterly Form 941, annual Form 940, Form W-2), withhold and remit employment taxes, and comply with state payroll tax requirements. These administrative obligations represent a significant increase in complexity compared to a sole proprietorship or default LLC.
Form 2553 deadline. To be effective for the current tax year, Form 2553 must be filed by March 15 of that year (for calendar-year entities) or within 2 months and 15 days of the beginning of the tax year. Late elections may be accepted under Rev. Proc. 2013-30 if certain requirements are met.
Eligibility. S-corp requirements under IRC §1361 include: no more than 100 shareholders, only U.S. citizen or resident individual shareholders (with exceptions for certain trusts and estates), one class of stock, and not an ineligible corporation. These requirements are easily met by most collectibles businesses.
QBI Deduction Under IRC §199A
The qualified business income (QBI) deduction under IRC §199A allows eligible taxpayers to deduct up to 20% of qualified business income from a qualified trade or business operated as a sole proprietorship or through a pass-through entity (partnership, S-corp, or LLC taxed as either). The deduction is taken on the individual tax return and reduces taxable income but not adjusted gross income.
Collectibles dealing is NOT an SSTB. The QBI deduction is limited or eliminated for “specified service trades or businesses” (SSTBs) at higher income levels. SSTBs include health, law, accounting, actuarial science, performing arts, consulting, athletics, financial services, brokerage services, and trades or businesses where the principal asset is the reputation or skill of employees or owners (§199A(d)(2)). Buying and selling collectibles is a retail or wholesale trade — it is not on the SSTB list. This means collectibles dealers are eligible for the full QBI deduction regardless of income level (subject to the W-2 wages/property limitations at higher incomes).
Income thresholds (2026). Below the threshold ($191,950 single / $383,900 married filing jointly, indexed annually), the deduction is simply 20% of QBI with no further limitations. Above the threshold, the deduction is limited to the greater of: (a) 50% of W-2 wages paid by the business, or (b) 25% of W-2 wages plus 2.5% of the unadjusted basis immediately after acquisition (UBIA) of qualified property. These limitations are relevant for high-income collectibles dealers.
Sole prop vs S-corp interaction. For a sole proprietor, the QBI deduction is 20% of Schedule C net income (subject to limitations). For an S-corp, the QBI deduction is 20% of the K-1 QBI amount, which equals net income minus the shareholder-employee’s W-2 wages. The W-2 wages paid to the shareholder-employee reduce QBI but count toward the W-2 wages limitation. The interaction is complex and fact-specific.
Which State to Form In?
Collectibles dealers frequently ask whether to form their LLC in their home state or in a state with perceived advantages, such as Delaware or Wyoming. For most single-owner collectibles businesses, the home state is the appropriate choice.
Home state formation. If the business operates in one state — the owner lives and works in that state, attends shows in that state, and ships from that state — forming the LLC in that state results in a single filing obligation. The LLC is registered and compliant in its home state.
Delaware. Delaware is popular for large corporations and venture-backed companies due to its well-developed corporate case law, Court of Chancery, and corporate-friendly statutes. For a single-owner collectibles business, Delaware formation provides minimal additional benefit. If the owner operates in another state (e.g., Texas), the Delaware LLC must also register as a “foreign LLC” in Texas, resulting in filing fees and compliance obligations in both states. Delaware charges a $300 annual franchise tax for LLCs.
Wyoming. Wyoming charges no state income tax and has low LLC filing fees ($100 initial, $60 annual). However, if the owner resides in a state with income tax, that state taxes the owner’s income regardless of where the LLC is formed. Wyoming formation does not avoid the home state’s income tax. The benefit is limited to Wyoming’s strong asset protection statutes, which may be relevant for specific legal planning situations.
Nexus. A collectibles dealer who attends card shows, conventions, or auctions in other states, or who has employees or inventory in other states, may have tax nexus in those states. Nexus creates filing obligations (income tax, sales tax, or both) in the nexus state regardless of where the LLC is formed. Online sales may also create economic nexus for sales tax purposes under South Dakota v. Wayfair (2018). Entity formation state does not determine nexus — the location of business activity does.
Annual Compliance
Each entity type carries specific ongoing compliance obligations. The following is a summary of the annual requirements by entity type:
Sole proprietorship. Schedule C filed with Form 1040 (due April 15). Quarterly estimated tax payments if applicable (Form 1040-ES). No separate entity return. No annual state filing unless a local business license requires renewal.
Single-member LLC (disregarded entity). Same federal filing as sole proprietorship (Schedule C on Form 1040). State annual report or franchise tax filing (varies by state). State filing fees (e.g., California $800 minimum franchise tax).
Multi-member LLC (partnership). Form 1065 due March 15. Schedule K-1 to each member by March 15. State annual report and franchise tax. Estimated tax payments by each member individually on Form 1040-ES.
S-corporation. Form 1120-S due March 15. Schedule K-1 to each shareholder by March 15. Quarterly payroll filings (Form 941). Annual FUTA (Form 940). W-2 to shareholder-employee by January 31. State annual report and franchise tax. Quarterly estimated tax payments by each shareholder individually. State withholding and unemployment filings if the state requires them.
The S-corp has the highest compliance burden. For a collectibles dealer considering the S-corp election, the FICA tax savings must exceed the additional accounting and payroll costs for the election to produce a net benefit. These costs typically include payroll processing ($30–$100/month), additional tax preparation fees ($500–$2,000+ for Form 1120-S vs. Schedule C), and the owner’s time managing the additional filings.
Worked Examples
Scenario A: Casual eBay Seller — $30,000 Gross Revenue
| Gross sales (eBay, card shows) | $30,000 |
| COGS + expenses | $22,000 |
| Net profit (Schedule C) | $8,000 |
| Entity recommendation | Sole prop with EIN |
At $8,000 net profit, the SE tax is approximately $1,130. An S-corp election would not produce meaningful FICA savings after accounting for payroll and filing costs. A sole proprietorship with an EIN (for platform W-9 requests) is the simplest structure. An LLC is optional for liability protection but does not change the federal tax result.
Scenario B: Card Show Dealer — $150,000 Gross Revenue
| Gross sales (shows, eBay, PWCC) | $150,000 |
| COGS + expenses | $90,000 |
| Net profit | $60,000 |
| SE tax as sole prop | ~$8,478 |
| FICA as S-corp ($40K salary) | ~$6,120 |
| Entity | LLC with S-corp election |
At $60,000 net profit, the S-corp election produces approximately $2,358 in FICA savings with a $40,000 salary. After payroll and additional filing costs (~$1,000–$2,000/year), the net benefit is modest but positive. The QBI deduction (§199A) applies: 20% of QBI ($60,000 − $40,000 W-2 = $20,000 QBI × 20% = $4,000 deduction). As a sole prop, the QBI deduction would be 20% × $60,000 = $12,000. The interaction between salary level and QBI is fact-specific.
Scenario C: Two Friends Flipping Cards — Multi-Member LLC
| Combined gross sales | $80,000 |
| COGS + expenses | $55,000 |
| Net profit | $25,000 |
| Allocation (50/50 per operating agreement) | $12,500 each |
| Entity | Multi-member LLC (partnership) |
Two people operating a business together are a partnership by default. A multi-member LLC formalizes the arrangement with an operating agreement that defines capital contributions, profit splits, management roles, and what happens if one partner wants to exit. The LLC files Form 1065 and issues K-1 to each member. Each member reports $12,500 on their individual return and pays SE tax on their share.

Frequently Asked Questions
A single-member LLC is treated as a disregarded entity by default under IRC §7701 and Treas. Reg. §301.7701-3. This means it is taxed identically to a sole proprietorship on Schedule C. The LLC does not change federal income tax treatment unless the owner makes an election (such as an S-corp election on Form 2553). A multi-member LLC is taxed as a partnership by default on Form 1065.
An S-corp election (Form 2553) can reduce self-employment tax when the business has net income sufficient to justify the additional administrative costs. The owner pays themselves a reasonable salary (subject to FICA/SE tax) and takes remaining profits as distributions (not subject to SE tax). This is generally relevant when net Schedule C income exceeds approximately $50,000–$75,000, though the specific threshold depends on individual circumstances.
No. The list of SSTBs under IRC §199A(d)(2) includes health, law, accounting, actuarial science, performing arts, consulting, athletics, financial services, brokerage services, and trades or businesses where the principal asset is the reputation or skill of employees or owners. Buying and selling collectibles is a retail/wholesale trade, not a specified service. Collectibles dealers operating as sole proprietors or through pass-through entities are eligible for the 20% QBI deduction, subject to applicable income thresholds.
For a single-owner collectibles business operating in one state, there is generally no federal tax advantage to forming in Delaware or Wyoming instead of the owner’s home state. The business must register as a foreign LLC in each state where it has nexus, which means filing fees and compliance obligations in both the formation state and the home state. Forming in the home state avoids the dual-filing requirement.
The self-employment tax rate is 15.3% on net self-employment income up to the Social Security wage base ($176,100 for 2026), consisting of 12.4% for Social Security and 2.9% for Medicare. Net SE income above the wage base is subject to only the 2.9% Medicare tax (plus the 0.9% Additional Medicare Tax on combined wages and SE income exceeding $200,000/$250,000). One-half of the SE tax is deductible as an above-the-line deduction under IRC §164(f).
