This is the question every new t-shirt seller gets stuck on: should I be a sole proprietor, form an LLC, or elect S-Corp status? The answer depends on how much you're making, how much risk you're carrying, and how much paperwork you're willing to deal with.
This guide covers only the structure decision — the pros, cons, tax math, and liability differences between sole proprietorship, LLC, and S-Corp for t-shirt businesses specifically. Once you've decided, our legal checklist walks you through the actual setup: EIN, sales tax permit, resale certificate, bank account, and insurance.
Quick answer
Many new t-shirt businesses start as a single-member LLC: state filing fees run from about $35 to $500 as of 2026 (most states fall between $50 and $200), it generally protects your personal assets if a customer or supplier sues, and it's taxed like a sole proprietorship by default. A sole proprietorship is often fine for a side hustle making under roughly $20,000 a year in profit, and an S-Corp election usually only starts to pay off once the business consistently clears somewhere around $60,000–$80,000 in annual profit and you're paying yourself a salary. The full comparison, costs, and tax math are below.

The Short Answer (If You Don't Want to Read the Whole Article)
| Your Situation | Common Structure | Why |
|---|---|---|
| Side hustle, under ~$20K/year profit | Sole proprietorship | Simplest. No state formation fee. Minimal paperwork. Lower exposure at this volume. |
| Growing business, ~$20K–$60K/year profit | LLC (taxed as sole prop) | Liability protection. Still simple taxes. Roughly $35–$500 in state filing fees. |
| Established business, ~$60K+ profit | LLC with S-Corp tax election | Same liability protection as an LLC, plus potential self-employment tax savings that can outweigh the added accounting costs. |
Now here's why — with the math.
What Each Structure Actually Is
Before comparing them, let's clear up a common confusion: an S-Corp is not a separate type of business. It's a tax election that an LLC or corporation files with the IRS. So the real decision is usually between two paths:
Path 1: Sole Proprietorship → LLC (when you want liability protection) → LLC with S-Corp election (when profits justify it)
Path 2: Jump straight to LLC from the start (if you want liability protection immediately)
Most t-shirt businesses follow Path 1 or Path 2. Here's what each structure means in practice:
Sole Proprietorship
You and the business are the same legal entity. No formation filing is required — if you sell a shirt and collect money, you're a sole proprietor by default (though your city or state may still require a business license or DBA). You report business income and expenses on Schedule C of your personal tax return. Your net profit is subject to both income tax and self-employment tax (15.3% for Social Security and Medicare, applied to 92.35% of net earnings).
What it feels like: You sell shirts, track expenses in a spreadsheet, and file one extra form at tax time. That's it.
LLC (Limited Liability Company)
A separate legal entity you create by filing paperwork with your state. Your personal assets (house, car, savings) are generally protected from business debts and lawsuits. By default, a single-member LLC is taxed identically to a sole proprietorship — same Schedule C, same self-employment tax. The difference is the legal wall between you and the business.
What it feels like: Same day-to-day operations and tax filing as a sole proprietorship, but you have a formal business entity with your name on it and a layer of asset protection.
LLC with S-Corp Tax Election
You form an LLC (for liability protection), then file IRS Form 2553 to have it taxed as an S-Corp. This changes how self-employment tax works: you pay yourself a "reasonable salary" (which is subject to payroll taxes), and the remaining profit comes out as a "distribution" (which is not subject to self-employment tax). You still have the LLC's liability protection.
What it feels like: You run payroll for yourself, file a separate business tax return (Form 1120-S), and typically need an accountant. More complexity, but potentially significant tax savings at higher income levels.
Liability Protection: Why It Matters for T-Shirt Businesses
T-shirt businesses face more liability exposure than many new sellers realize. Here are the kinds of scenarios that come up:
Copyright/trademark infringement. You use a phrase on a shirt that turns out to be trademarked. The trademark holder sends a cease-and-desist letter, then sues for damages. Without liability protection, your personal bank account and assets could be on the line for those damages. With an LLC, generally only business assets are at risk (though an LLC does not shield you from liability for your own intentional wrongdoing).
Product liability. A customer has a skin reaction to the vinyl or ink on a shirt you made. Or a child's shirt has a design element that becomes a safety concern. Product liability claims can be expensive even if you did nothing wrong — legal defense alone costs money. An LLC helps separate these claims from your personal assets.
Customer disputes. A bulk order for a local business goes wrong — wrong colors, wrong sizes, missed deadline. The customer demands a refund that exceeds what's in your business account. Without an LLC, they can pursue your personal assets for the difference.
Craft fair / event accidents. Someone trips over your heat press cord at a market. Their medical bills exceed your insurance coverage. Without an LLC, you're personally liable for the excess.
Does every t-shirt seller need liability protection? No — if you're making 5 shirts a month for friends, the risk is minimal. But the moment you're selling to strangers, taking custom orders, selling at events, or doing any meaningful volume, the exposure is real.
| Structure | Personal Asset Protection | Important Caveat |
|---|---|---|
| Sole Proprietorship | None — you and the business are the same | All your personal assets are exposed to business claims |
| LLC | Yes — business and personal are separate entities | Protection can be "pierced" if you mix personal and business finances |
| LLC with S-Corp election | Yes — same as LLC | Same piercing risk applies |
Critical point: LLC liability protection only works if you keep business and personal finances completely separate. Separate bank account, separate credit card, don't pay personal bills from the business account. If you commingle funds, a court can "pierce the corporate veil" and hold you personally liable anyway. Our legal checklist covers how to set up your business bank account properly.
Tax Math: What You Might Save (or Not) at Each Level
This is where most articles get vague. Here's a simplified comparison at three common profit levels for t-shirt businesses. These examples look only at federal Social Security and Medicare taxes (self-employment tax vs. payroll tax) to isolate the main difference between the structures. They ignore state income tax, state-level S-Corp taxes or fees, the deduction for half of self-employment tax, and the Qualified Business Income (QBI) deduction — all of which can shift the result. Treat these as illustrations, not a calculation for your return.
Two mechanics matter for the math: self-employment tax is 15.3% applied to 92.35% of net profit (so the effective rate is about 14.1% of profit), while S-Corp payroll taxes are the full 15.3% of salary (7.65% employee share plus 7.65% employer share).
Scenario 1: Side Hustle — $25,000/Year Profit
| Sole Prop / Default LLC | LLC + S-Corp Election | |
|---|---|---|
| Profit | $25,000 | $25,000 |
| Reasonable salary | N/A | ~$25,000 (at this profit level a reasonable salary would likely consume most or all of it) |
| Distribution | N/A | ~$0 |
| SE tax / payroll tax | ~$3,530 (15.3% × 92.35% × $25,000) | ~$3,825 (15.3% payroll tax on salary) |
| Added S-Corp costs (payroll service, extra tax return) | $0 | Roughly $1,500–$3,000/year |
| Net savings from S-Corp | — | None — it costs you more |
Verdict: S-Corp makes no sense at $25K. Your profit isn't high enough to split between salary and distributions meaningfully, and the added accounting costs eat any theoretical savings. Stay as a sole proprietorship or default LLC.
Scenario 2: Growing Business — $60,000/Year Profit
| Sole Prop / Default LLC | LLC + S-Corp Election | |
|---|---|---|
| Profit | $60,000 | $60,000 |
| Reasonable salary | N/A | $36,000 (example only) |
| Distribution | N/A | $24,000 |
| SE tax / payroll tax | ~$8,480 | ~$5,510 (on salary only) |
| Payroll tax savings | — | ~$2,970 |
| Added S-Corp costs | $0 | Roughly $1,500–$3,000/year |
| Net annual savings | — | Roughly $0–$1,500 |
Verdict: S-Corp starts making sense around $60K, but barely. The savings may only just cover the extra accounting costs. This is the "maybe" zone — it depends on how much your accountant charges, your state's treatment of S-Corps, and whether you want the added complexity. Many owners wait until they're consistently at this level for a full year before electing S-Corp.
Scenario 3: Established Business — $100,000/Year Profit
| Sole Prop / Default LLC | LLC + S-Corp Election | |
|---|---|---|
| Profit | $100,000 | $100,000 |
| Reasonable salary | N/A | $50,000 (example only) |
| Distribution | N/A | $50,000 |
| SE tax / payroll tax | ~$14,130 | ~$7,650 (on salary only) |
| Payroll tax savings | — | ~$6,480 |
| Added S-Corp costs | $0 | Roughly $1,500–$3,000/year |
| Net annual savings | — | Roughly $3,500–$5,000 |
Verdict: This is usually S-Corp territory. Saving several thousand dollars a year generally justifies the extra accounting costs. At $100K+ in profit, many tax professionals will at least run the numbers on an S-Corp election for you — but the final answer depends on your state and the rest of your tax picture.
One more factor — the QBI deduction. Sole proprietors, LLC owners, and S-Corp shareholders can generally deduct up to 20% of qualified business income under Section 199A, which was made permanent by Public Law 119-21 in July 2025. S-Corp wages you pay yourself are not qualified business income, so electing S-Corp status can shrink this deduction. Your accountant should model both effects together.
"Reasonable Salary" — What the IRS Expects
The S-Corp tax savings come from splitting profit between salary (subject to payroll tax) and distributions (not subject to self-employment tax). But the IRS requires your salary to be "reasonable compensation" — meaning roughly what you'd pay someone else to do the same work.
You can't pay yourself $10,000 and take $90,000 in distributions. The IRS looks at your role, the hours you work, and what comparable employees earn. There is no official IRS percentage; for an owner who designs, produces, markets, and ships product, a defensible salary often ends up being a substantial share of profit. Setting it too low invites scrutiny; setting it too high negates the S-Corp benefit.
This is where an accountant earns their fee — they'll help you set a defensible salary based on your specific situation.
Formation Costs and Ongoing Requirements
All figures below are approximate ranges as of 2026 and vary by state.
| Sole Proprietorship | LLC | LLC + S-Corp Election | |
|---|---|---|---|
| Formation cost | $0–$100 (DBA filing only, if needed) | $35–$500 (state filing fees; most states $50–$200) | Same as LLC + $0 for IRS Form 2553 |
| Annual state fees | $0–$100 (business license renewal, where required) | $0–$800 (annual report and/or franchise tax, varies by state) | Same as LLC; some states add S-Corp-level taxes or fees |
| Tax filing | Schedule C on personal return | Same as sole prop (for single-member LLC) | Form 1120-S (business return) + personal return |
| Payroll | Not required | Not required | Required — must run payroll for yourself |
| Accounting cost | $0–$300 (simple return) | $0–$300 (same as sole prop for taxes) | Roughly $1,500–$3,000/year (payroll + business return) |
| Record-keeping | Track income and expenses | Same + keep LLC operating agreement on file | Same + payroll records |
State-specific note: Some states charge significant annual LLC fees regardless of profit. California, for example, charges an $800 annual LLC tax as of 2026, which eats into the benefit for low-revenue businesses. Check your state's annual LLC costs before filing — it may affect your timing.
When to Switch Structures
Most t-shirt businesses evolve through structures over time. Here are the common triggers:
Sole Proprietorship → LLC: Make this move when you start selling to strangers regularly, begin taking custom orders, sell at events, or when your revenue reaches a point where you have something worth protecting. Many sellers form an LLC before their first craft fair or Etsy launch. Cost: roughly $35–$500 one-time state filing.
LLC → LLC with S-Corp election: Consider this when your annual profit consistently exceeds roughly $60,000–$80,000. Key word: consistently. One good year doesn't justify the switch. Wait until you've had 12+ months at this level. File IRS Form 2553 no later than two months and 15 days after the start of the tax year you want the election to apply to (or after the formation date for a new entity). If you miss the deadline, the IRS has a late-election relief procedure — ask your accountant.
What "converting" actually involves:
- Sole prop → LLC: File Articles of Organization with your state. Check whether you need a new EIN (the IRS has a "Do you need a new EIN?" page; many banks will want one for the LLC regardless). Open a new business bank account. Transfer any business assets. Update your Etsy/Shopify/PayPal accounts with the new business name and EIN.
- LLC → S-Corp election: File Form 2553 with the IRS. Set up a payroll system (Gusto, QuickBooks Payroll, or similar — typically a few dozen dollars per month). Hire an accountant or tax preparer who handles S-Corp returns. Usually no change to your LLC with the state — it's a federal tax election — but confirm whether your state requires its own S-Corp election or filing.
The Biggest Mistake: Choosing Based on What Sounds Professional
New sellers sometimes form an LLC or elect S-Corp status because it "sounds more legitimate" or because someone in a Facebook group told them to. The structure should match your actual situation, not your aspirations.
If you're making $500/month selling shirts on Etsy, paying $800/year in California LLC tax and $2,000/year for S-Corp accounting doesn't make financial sense. Start simple. You can always upgrade later — and the conversion process is straightforward.
Conversely, if you're doing $80K+/year in profit and still operating as a sole proprietor, you may be paying thousands in unnecessary self-employment tax and exposing your personal assets. At that level, the LLC + S-Corp election often pays for itself.
Frequently Asked Questions
Do I need an LLC to sell t-shirts?
No. You can legally sell t-shirts as a sole proprietor with whatever business license and sales tax permit your state and city require. An LLC adds liability protection but isn't legally required. That said, if you're selling to strangers, taking custom orders, or attending events, many sellers consider the protection worth the state filing fee.
Can I change my business structure later?
Yes. Sole proprietorship to LLC is a common upgrade — file with your state, sort out your EIN, update your accounts. LLC to S-Corp election is even simpler — file Form 2553 with the IRS. You don't need to dissolve anything or start over.
What if my spouse helps with the business?
If you file jointly and both materially participate in an unincorporated business, the IRS lets married couples elect "qualified joint venture" treatment instead of filing as a partnership. Note that this election is generally not available to a state-law LLC, except in community property states under IRS guidance. If you want to pay your spouse a salary (for S-Corp purposes or to build their Social Security credits), you'll need to set up payroll. Talk to your accountant about the best approach for your situation.
Should I use an online LLC formation service (LegalZoom, ZenBusiness, etc.)?
These services file the same paperwork you can file yourself — they just do it for you. Their base packages typically range from $0 to a few hundred dollars plus state fees. They're convenient but not necessary. You can file directly with your state's Secretary of State website for just the state filing fee. The services often upsell registered agent service, operating agreement templates, and EIN filing — things you can do yourself for free or much cheaper.
How much does it cost to form an LLC for a t-shirt business?
As of 2026, state filing fees range from about $35 (Montana) to $500 (Massachusetts), with Kentucky ($40) and Arkansas ($45) near the low end and most states in the $50–$200 range. Add $0 for an EIN (free directly from the IRS), $0–$100 for an operating agreement (free templates available online), and $0–$300 per year for a registered agent service if you don't serve as your own. Total: roughly $35–$500 up front in most cases, plus your state's annual fees. Our legal checklist covers each step with links.
