Should You Register Your Reselling Business? LLC vs Sole Proprietor

As your reselling business grows on platforms like eBay, Depop, Poshmark, and Vinted, you will eventually face an important question: should you formally register your business? And if so, what structure should you choose? This guide compares the most common options for resellers in the US and UK, breaks down the real costs, and helps you decide when the time is right to make it official.

Understanding Your Options

Most resellers start as sole proprietors by default. If you sell items and report the income on your personal tax return, you are already operating as a sole proprietor — no registration required. But as revenue grows, you may want the liability protection, tax advantages, or professional credibility that comes with a formal business structure.

Sole Proprietorship (US) / Sole Trader (UK)

This is the simplest structure and where every reseller begins. There is no legal separation between you and your business.

Advantages:

• No registration fees or paperwork to start
• Simple tax filing — report on Schedule C (US) or Self Assessment (UK)
• Complete control over business decisions
• No annual state filing requirements
• Easy to dissolve — just stop doing business

Disadvantages:

• No personal liability protection — your personal assets are at risk if someone sues your business
• Harder to build business credit
• May appear less professional to wholesale suppliers
• Cannot bring on partners without changing structure

For resellers earning under $20,000 per year on platforms like eBay and Etsy, sole proprietorship is usually perfectly adequate.

Limited Liability Company (LLC) — US

An LLC creates a legal separation between your personal assets and your business. It is the most popular formal structure for small resellers in the US.

Advantages:

• Personal liability protection: Your personal savings, home, and car are generally protected from business debts and lawsuits
• Flexible tax treatment — taxed as sole proprietor by default, with option to elect S-Corp taxation
• Professional credibility with suppliers and wholesale accounts
• Can open business bank accounts and credit cards more easily
• Relatively simple to set up and maintain

Disadvantages:

• Filing fees vary by state ($50-$500 to form)
• Annual fees and reports required in most states
• Some states charge franchise taxes regardless of income
• More complex tax filing

LLC Formation Costs by State

The cost to form an LLC varies significantly by state. Here are some common examples:

If you use a registered agent service (recommended for privacy), add $100-$300 per year. Services like Northwest Registered Agent or ZenBusiness can handle formation for $39-$199 plus state fees.

Limited Company (Ltd) — UK

The UK equivalent of an LLC is a Limited Company (Ltd). It provides similar liability protection and is registered through Companies House.

Key details:

• Registration fee: £12 online (or £30 by post)
• Corporation Tax rate: 25% on profits (19% for profits under £50,000 via small profits rate)
• Must file annual accounts with Companies House
• Must file a Corporation Tax return with HMRC
• Directors can pay themselves a combination of salary and dividends for tax efficiency
• Annual confirmation statement: £13

For UK resellers on eBay and Vinted earning over £30,000-£40,000 in profit, a Ltd can offer meaningful tax savings compared to sole trader status, particularly through the salary-and-dividends strategy.

S-Corp Election — US

An S-Corp is not a business structure itself — it is a tax election that an LLC (or corporation) can make by filing Form 2553 with the IRS. It changes how your business income is taxed.

How it works:

• You pay yourself a "reasonable salary" as an employee of the business
• Remaining profits are distributed as dividends, which are not subject to self-employment tax (15.3%)
• Only the salary portion is subject to payroll taxes

Example: Your reselling business earns $80,000 in profit. As a sole proprietor, you would owe self-employment tax on the full $80,000 (approximately $12,240). With an S-Corp election, you pay yourself a reasonable salary of $40,000 and take the remaining $40,000 as a distribution. You save roughly $6,120 in self-employment tax.

When S-Corp makes sense:

• Net profit consistently exceeds $50,000-$60,000 per year
• You can justify a reasonable salary that is lower than total profits
• You are willing to run payroll (cost: $20-$50/month with services like Gusto or Wave Payroll)

When it does not make sense:

• Profits are under $40,000 — the payroll costs and added complexity outweigh savings
• Your profits fluctuate dramatically year to year
• You are uncomfortable with payroll administration

When Should You Incorporate?

There is no magic revenue number, but here are practical guidelines for resellers selling on platforms like eBay, Depop, Poshmark, and Etsy:

Consider an LLC When:

• Revenue exceeds $20,000-$30,000 per year — at this point, the liability protection justifies the cost
• You carry valuable inventory — if you hold $5,000+ in inventory, protecting personal assets becomes important
• You want wholesale accounts — many suppliers require a business entity and resale certificate
• You ship high-value items — the risk of claims or disputes increases
• You hire helpers — even part-time employees increase your liability exposure

Consider S-Corp Election When:

• Net profit consistently exceeds $50,000-$60,000
• You are comfortable running payroll
• You want to minimize self-employment tax

Stay Sole Proprietor When:

• Revenue is under $15,000-$20,000 per year
• You sell low-risk items (clothing, books, small goods)
• You are testing whether reselling is a viable long-term business
• You want to keep things simple and low-cost

Practical Steps to Register Your Business

If you have decided to formalise your reselling business, follow these steps:

Step 1: Get an EIN (Employer Identification Number)

Apply for an EIN from the IRS at irs.gov — it is free and you receive it immediately. An EIN is like a Social Security number for your business. You need it to open a business bank account, file taxes, and hire employees. In the UK, your UTR (Unique Taxpayer Reference) from HMRC serves a similar purpose.

Step 2: Register Your LLC or Ltd

In the US, file your Articles of Organisation with your state's Secretary of State office. Most states offer online filing. In the UK, register your Ltd at Companies House online for £12.

Step 3: Open a Business Bank Account

Separate your personal and business finances completely. Bring your EIN, Articles of Organisation, and photo ID to any bank. Many online banks (Mercury, Relay, Bluevine) offer free business checking accounts. This separation is essential for maintaining your LLC's liability protection.

Step 4: Get a Sales Tax Permit

If you sell through your own website or at local events (not just through marketplaces like eBay that handle tax collection), you need a sales tax permit in your home state. Apply through your state's Department of Revenue. This also lets you obtain a resale certificate for buying inventory tax-free.

Step 5: Consider Business Insurance

General liability insurance for a small reselling business typically costs $300-$600 per year. It covers:

• Product liability claims (if an item you sold causes injury)
• Damage to items while in your possession
• Legal defence costs

Companies like Next Insurance and Hiscox offer affordable policies tailored to e-commerce sellers. If you hold significant inventory in your home, check whether your homeowner's or renter's insurance covers business property — most standard policies do not.

Managing Your Registered Business

Once you are set up, keep your business in good standing with these ongoing tasks:

• File your annual report with the state (due dates vary)
• Pay any franchise taxes or annual fees
• Maintain a separate bank account and never mix personal and business funds
• Keep meeting minutes for LLC members (even if you are the only member)
• File taxes on time — quarterly estimated payments for federal, annual returns for state
• Use tools like ListingGenie to track inventory across eBay, Depop, and other platforms, keeping your records organised for tax time

Frequently Asked Questions

• Do I need an LLC to sell on eBay or Poshmark?

  No. You can sell on any reselling platform as a sole proprietor. An LLC is optional and primarily provides liability protection and professional credibility. Platforms like eBay, Poshmark, Depop, and Vinted all allow individual sellers without a business entity.

• Can I form an LLC in a different state than where I live?

  Yes, but it usually creates more complexity than benefit for small resellers. You would need a registered agent in that state and may still need to register as a foreign LLC in your home state. For most resellers, forming in your home state is simplest and cheapest.

• How much does it cost per year to maintain an LLC?

  Annual costs vary by state but typically range from $50-$800 per year for state fees alone. Add $100-$300 for a registered agent, $20-$50/month for payroll if you elect S-Corp status, and $200-$500 for a tax professional. Total annual cost is typically $300-$2,000.

• Will an LLC protect me from platform disputes?

  An LLC protects your personal assets from business liabilities, but it does not change how platforms handle disputes. If a buyer opens a case on eBay, the platform's resolution process applies regardless of your business structure.

• When should I switch from sole proprietor to LLC?

  Consider switching when your annual revenue consistently exceeds $20,000, you hold valuable inventory, you want to pursue wholesale accounts, or you simply want the peace of mind that comes with liability protection.

• Can I convert my sole proprietorship to an LLC without disrupting my eBay or Depop accounts?

  Yes. You can update your seller account information with your new business name and EIN. Platforms like eBay allow you to update your account details without creating a new account. Your selling history and feedback will be preserved.
