Can I send invoices without registering a business in the US?

February 2, 2026

You can usually send invoices in the US without registering an LLC or corporation. Freelancers, side hustlers, and sole proprietors can invoice clients legally using their personal name, as long as they follow tax, licensing, and naming rules. This guide explains how to invoice confidently without formal business registration.

Can I send invoices without registering a business in the US?

If you’re starting out in the United States—freelancing on the side, testing a new service idea, selling a few digital products, or helping neighbors with odd jobs—you may want to get paid professionally without immediately forming an LLC or corporation. A very common question follows: can you send invoices without registering a business in the US?

In most cases, yes. You can usually invoice clients as an individual (often as a “sole proprietor” by default) without creating a formal business entity. But “can” doesn’t mean “no rules.” The US has a patchwork of federal, state, and local requirements around taxes, licensing, and names you use publicly. The good news is that invoicing itself is not the same thing as incorporating a company. The more important question is whether you’re allowed to perform the work, how you report and pay taxes, and whether any permits or registrations apply to your situation.

This guide explains what’s typically allowed, what to watch out for, and how to invoice confidently as an individual—using an invoicing tool like invoice24 to keep everything clear, trackable, and professional.

Invoicing is a payment request, not a business license

An invoice is essentially a written request for payment. It documents what you provided, how much it costs, and when payment is due. In the US, there is no single federal “invoice law” that says you must be registered as a business to issue invoices. People invoice every day without a formal entity: independent contractors, gig workers, consultants, tutors, home repair helpers, artists, and many others.

However, invoicing is usually part of doing business. That means you should treat it as a real financial activity: keep accurate records, be transparent with clients, and understand your tax responsibilities. Registering a business entity is one way to structure your work, but it is not the only way to operate.

What you are by default: a sole proprietor

If you’re earning money on your own in the US and you haven’t formed a separate legal entity, you’re typically operating as a sole proprietor by default. “Sole proprietor” isn’t a special license you apply for—it’s a common legal and tax classification that describes what’s happening: an individual doing business for profit.

As a sole proprietor, you can:

  • Provide services or sell goods under your personal name.
  • Send invoices to clients using your name and contact details.
  • Use a separate business bank account (optional but recommended).
  • Deduct eligible business expenses (if you meet the rules) and report income on your tax return.

But you also take on some responsibilities:

  • You generally report business income and expenses on your personal tax return.
  • You may owe self-employment taxes if you have net earnings from self-employment.
  • You may need to register for certain state/local taxes or business licenses depending on what you do and where you do it.

So if you’re not registered as an LLC or corporation, you’re not “doing it illegally” by invoicing. You’re just operating in the simplest form: as yourself.

When you can invoice without registering a business entity

Many situations allow you to invoice as an individual without forming an LLC or corporation. Common examples include:

  • Freelance work (design, writing, development, marketing, consulting, coaching).
  • Local services (handyman help, landscaping, cleaning, tutoring, pet care).
  • Creative work (photography, video editing, music lessons, art commissions).
  • Digital products or small e-commerce sales at an early stage.
  • Short-term or trial projects to validate a business idea.

In these cases, you can generally send invoices in your own name, collect payment, and report that income. Your client often doesn’t care whether you’re an LLC—what they care about is that the invoice is clear, accurate, and includes enough details to pay you and reconcile their records. That’s where invoice24 helps: you can generate professional invoices with line items, due dates, payment terms, taxes or discounts if needed, and a clean, consistent format.

Business registration vs. other required registrations

One of the biggest misunderstandings is thinking “I’m not an LLC, so I don’t have to register anything.” In reality, there are different kinds of registrations, and some may apply even if you never form an LLC. Here are the main categories:

1) Entity formation (LLC/corporation)

This is what most people mean by “registering a business.” Forming an LLC or corporation creates a separate legal entity. This is optional for many small, early-stage sole proprietors.

2) Business name registration (DBA / assumed name)

If you invoice under a name that is not your legal personal name (for example, “Brightline Web Studio” instead of “Jordan Lee”), you may need to file a DBA (Doing Business As) or assumed name registration in your state, county, or city. Rules vary widely. Some places require it to operate under a trade name, while others have different thresholds. The key idea: using a business name can trigger name registration requirements even if you don’t form an LLC.

If you use invoice24, you can choose whether your invoices show your personal legal name, a business name, or both—helpful if you’re keeping things simple at first and want to avoid confusion.

3) Licenses and permits

Some activities require licenses or permits regardless of whether you’re an LLC. For example, regulated fields (certain construction trades, cosmetology, childcare, financial services, insurance, and more) can have strict licensing rules. Some cities require a general business license for anyone operating locally, including sole proprietors. Always consider whether your specific work is regulated.

4) Tax registrations

If you sell taxable goods or taxable services in a state that requires sales tax collection, you may need to register for a sales tax permit (sometimes called a seller’s permit). This is separate from forming a company. Also, if you have employees later, payroll tax registrations come into play—but that’s usually not relevant when you’re simply invoicing as a solo worker.

Invoicing as an individual: what to include on your invoices

Even if you’re not a registered business entity, your invoice should look complete and professional. A clear invoice reduces payment delays, prevents disputes, and makes bookkeeping easier for both sides. Here’s what to include:

  • Your name or business name: If you’re invoicing as an individual, your legal name is usually safest.
  • Your contact info: Email address and phone number (and mailing address if needed).
  • Client information: Their name, company name, and billing address if applicable.
  • Invoice number: A unique number for tracking and recordkeeping.
  • Invoice date: The date you issued the invoice.
  • Due date and payment terms: For example, “Due upon receipt,” “Net 7,” “Net 15,” or “Net 30.”
  • Description of goods/services: Clear line items, quantities, hours, rates, and deliverables.
  • Subtotal, taxes (if applicable), discounts, total: A clear breakdown of charges.
  • Payment instructions: How to pay you—bank transfer, card, or other methods you accept.
  • Notes or late fee policy (optional): If you charge late fees, state it clearly up front.

Invoice24 is built to include all of these essentials: automatic invoice numbering, client and item libraries, editable terms, and a consistent invoice layout that looks credible whether you’re a one-person freelancer or a growing team.

Do you need an EIN to send invoices?

An EIN (Employer Identification Number) is a tax ID issued by the IRS. Many people think an EIN is required to invoice, but that’s not generally true. You can invoice using your Social Security Number (SSN) for tax reporting purposes. That said, there are reasons you might choose to get an EIN even as a sole proprietor:

  • Privacy: You may prefer not to share your SSN with clients on forms like a W-9.
  • Professionalism: Some clients expect an EIN, even if not legally required.
  • Banking: Some banks prefer or require an EIN to open certain business accounts.
  • Future growth: If you later hire employees or form an LLC, you may need an EIN anyway.

But for sending invoices, an EIN is usually optional. Many sole proprietors operate for years invoicing clients without one, especially for smaller projects.

What about a W-9 and 1099 forms?

In the US, clients often request a W-9 form from independent contractors before paying them. A W-9 provides the client with your name, address, and taxpayer identification number (SSN or EIN) so they can report payments if required. This is common in business-to-business arrangements.

If you’re paid as a contractor, your client may issue a 1099 form (such as a 1099-NEC) reporting how much they paid you during the year. This doesn’t change whether you can invoice—it’s simply part of the tax reporting process.

Important practical point: the invoice and the W-9 serve different purposes. Your invoice is your payment request. The W-9 is your tax identification disclosure to the payer. You can invoice without a W-9, but some clients won’t pay until they have it on file.

Sales tax: when invoicing can trigger tax collection obligations

Sales tax is one of the main areas where invoicing can get tricky. Whether you must charge sales tax depends on:

  • The state (and sometimes local jurisdiction) where you have tax obligations.
  • Whether what you sell is taxable (goods are often taxable; services vary widely).
  • Whether you have “nexus” in a state (a connection that creates a tax responsibility).

If you’re providing services (like design or consulting), you may not need to charge sales tax in many states, but there are exceptions. If you’re selling physical goods, sales tax is more likely to apply. If sales tax does apply, you generally need to register, collect tax, and file returns—even if you’re not an LLC.

A well-structured invoice makes sales tax compliance easier. With invoice24, you can show tax as a separate line, apply tax rates where needed, and keep records of taxable vs. non-taxable items.

Using a business name: should you invoice under your personal name or a brand?

If you’re not registered as a business entity, the simplest approach is to invoice under your legal name. This reduces confusion, makes tax forms straightforward, and often avoids additional registrations.

However, you might still want a brand name for marketing—especially if you have a portfolio website or plan to grow. The safest middle-ground is often to show both on the invoice, such as:

  • “Jordan Lee (Brightline Web Studio)”
  • “Brightline Web Studio — owned and operated by Jordan Lee”

This signals professionalism while keeping your identity clear. If you do choose to invoice under a brand name alone, look into whether a DBA/assumed name registration is required where you operate. Even if you don’t register, be consistent: whatever name appears on invoices should match the name tied to your payment method and tax documents to avoid payment delays.

Getting paid without a business entity: practical payment considerations

Invoicing is only half the picture; getting paid smoothly matters just as much. Clients want an easy way to pay, and you want payments to be trackable and professional. Even as an individual, you can set up reliable payment workflows:

  • Bank transfer details: Provide clear instructions and reference information (invoice number, your name).
  • Card payments (optional): Some clients prefer cards; fees may apply depending on your payment provider.
  • Payment deadlines: Set and communicate due dates to reduce “I forgot” delays.
  • Payment reminders: Send polite, scheduled reminders before and after the due date.

Invoice24 helps you organize these steps by keeping invoice histories, due dates, and client records in one place—making it easier to follow up without feeling awkward or losing track.

Recordkeeping: the real reason to invoice properly

Whether you register a business entity or not, your records matter. Clear invoicing and bookkeeping can protect you in disputes, simplify tax filing, and help you understand whether your work is actually profitable.

Good records include:

  • Copies of invoices sent and paid.
  • Proof of payment (bank statements, payment confirmations).
  • Contracts, proposals, or written scope agreements.
  • Receipts for business expenses (software, equipment, supplies, mileage, etc.).
  • Notes about refunds, discounts, or changes in scope.

When you treat invoicing as a system, you reduce stress. Tools like invoice24 make it easy to keep consistent invoice numbers, store client details, and maintain an organized payment trail—all critical if you’re ever asked to document your income.

Common scenarios: what’s allowed and what to watch for

Let’s break down a few typical situations and what they generally mean for invoicing without business registration.

Freelancer providing services to companies

Usually fine to invoice as your legal name as a sole proprietor. Expect some clients to request a W-9. Make your invoice clear with scope, rate, and due date.

Side hustle selling a few products locally or online

You can invoice, but you might need to think about sales tax and whether you should register for a sales tax permit. If you’re selling in person or within a state, local rules can matter.

One-time gig (photography shoot, tutoring package, short consulting project)

Generally straightforward: invoice in your name, keep a record, report income. If the client is a business, they may ask for a W-9.

Using a brand name on invoices without registering it

You can sometimes do this, but it can create issues: clients may be confused about who to pay, and some jurisdictions require DBA filings. Also, your payment account name should match invoice details as closely as possible.

Working in a regulated trade

This is where entity formation is not the issue; licensing is. If a trade requires a license, you may need it regardless of whether you have an LLC. Invoicing doesn’t make the work legal if the work itself requires licensing.

Do you need a registered address to invoice?

Not necessarily. Many individuals invoice using their home address, a mailing address, or sometimes just email and phone details. That said, some clients (especially larger companies) prefer a complete billing address on invoices for their records. If you’re concerned about privacy, you might consider using a mailing address solution, but that’s a personal decision and may involve extra cost.

Invoice24 lets you customize what appears on the invoice so you can strike the right balance between professionalism and privacy based on your client’s needs and your comfort level.

Should you form an LLC anyway?

You can invoice without forming an LLC, but you might still choose to form one later. The most common reasons are:

  • Liability separation: An LLC can help separate business liabilities from personal assets (though it’s not a magic shield and must be maintained properly).
  • Brand clarity: Your business name becomes more official and consistent.
  • Client expectations: Some corporate clients prefer contracting with entities.
  • Banking and finance: It may be easier to open accounts, apply for credit, or set up vendor relationships.
  • Scaling: If you plan to hire or expand, a formal structure can help.

However, forming an LLC also introduces costs and administrative tasks: state filing fees, annual reports in many states, possible publication requirements in certain places, separate accounting practices, and more. For many people, it makes sense to begin as a sole proprietor, build steady income, and then formalize when the benefits clearly outweigh the complexity.

How to make your invoices look credible as a non-registered business

Some people worry that clients will take them less seriously if they’re not an LLC. In practice, professionalism comes from clarity and consistency. Here are ways to make your invoices feel “real” even when you’re invoicing as an individual:

  • Use consistent branding: A logo and clean layout help, even if you’re invoicing under your name.
  • Use sequential invoice numbers: This signals organization and helps both sides track payments.
  • Provide detailed line items: “Design services” is vague; “Homepage design (8 hours @ $X/hr)” is clear.
  • State payment terms clearly: Include due date, accepted payment methods, and late fee policy if applicable.
  • Include your tax identity correctly on forms: If asked for a W-9, complete it accurately to avoid payment issues.
  • Send invoices promptly: Timely invoicing reduces delays and increases trust.

Invoice24 is designed to deliver this kind of professional presentation by default: structured line items, configurable terms, and a polished invoice format that works for clients of all sizes.

Late payments: what to do when you’re invoicing as an individual

Late payments happen to everyone, especially when you’re new and clients aren’t used to your process yet. Being an individual doesn’t mean you have fewer options. You can still follow a professional collections workflow:

  • Send a friendly reminder before the due date: A short note like “Just a reminder this invoice is due on Friday.”
  • Follow up promptly after the due date: Assume good intent: “Wanted to check if you had everything you need to process payment.”
  • Resend the invoice: Sometimes it was simply buried in email.
  • Offer simple payment options: The easier it is to pay, the faster you get paid.
  • Escalate professionally: Reference your terms and request a clear payment date.

Having a clean invoice history in invoice24 helps here: you can quickly reference invoice numbers, dates, totals, and what was delivered—so your follow-ups are factual and organized rather than emotional.

Refunds, deposits, and partial payments

You don’t need a registered business to use common invoicing practices like deposits or milestone billing. In fact, these practices can be especially important when you’re working as an individual because they reduce risk.

  • Deposits: Request a portion up front to secure time and cover initial costs.
  • Milestones: Bill at key delivery points for larger projects.
  • Partial payments: Allow clients to pay in installments if that helps close the deal.
  • Clear refund policy: State what is refundable and under what conditions.

Invoice24 makes these workflows straightforward by letting you itemize work, apply discounts, track what’s been paid, and keep your terms visible on the invoice.

Cross-border clients: invoicing from the US to clients abroad (or vice versa)

If you’re in the US and you invoice clients in other countries, you can typically still invoice as an individual. The main differences are practical rather than legal: currency, payment methods, and how your client handles their own tax compliance. Some international clients may request specific invoice details for their VAT or bookkeeping processes, even if you’re not charging VAT. Keep your invoice descriptions clear, specify currency, and confirm the client’s billing requirements early.

For non-US individuals doing work for US clients, the situation can involve additional tax forms (such as documentation of foreign status). But again, that’s about tax paperwork, not whether you’re “allowed” to issue an invoice.

What you should avoid when invoicing without registering a business

Invoicing is usually allowed, but there are a few pitfalls to avoid:

  • Misrepresenting your status: Don’t claim you’re an LLC or corporation if you’re not.
  • Ignoring licenses: If your work requires a license, invoicing doesn’t bypass that requirement.
  • Collecting sales tax without registration (where required): If you must collect tax, register properly and file returns.
  • Mixing personal and business records excessively: It’s not illegal, but it becomes a nightmare at tax time.
  • Vague invoices: Vague descriptions lead to disputes and delayed payments.

Staying organized is the easiest way to stay safe and professional. A consistent tool like invoice24 reduces mistakes by standardizing your invoice content and keeping everything stored and searchable.

A simple step-by-step: sending your first invoice as an individual

If you want a straightforward plan, here’s a practical checklist:

  1. Use your legal name (at least initially): Avoid confusion and extra name registration requirements.
  2. Agree on scope and price in writing: Even a short email confirmation helps.
  3. Create a professional invoice: Include invoice number, date, line items, total, and due date.
  4. Set clear payment terms: For example, Net 7 or Net 15 for smaller projects.
  5. Provide simple payment instructions: Make paying easy and unambiguous.
  6. Track the invoice: Note when it was sent, viewed, and paid if your process supports it.
  7. Send reminders if needed: Polite and consistent follow-ups work.
  8. Save records: Keep invoices and payment confirmations for taxes and bookkeeping.

Invoice24 is designed for this exact workflow: you can set up your sender details once, create clients, add your services as reusable items, generate an invoice in seconds, and keep your records organized from day one.

FAQ: quick answers to common invoicing questions

Can I invoice a company as an individual?

Yes. Many companies regularly pay individual contractors and freelancers. They may ask you for a W-9 so they can handle tax reporting properly.

Can I invoice without an LLC if I’m just doing a few jobs?

In most cases, yes. You can invoice as a sole proprietor by default. The key is to report income accurately and follow any relevant local licensing or tax rules.

Will clients take me seriously if I’m not registered?

Most clients care about clarity, professionalism, and reliability. A well-structured invoice with clear terms and accurate details often matters more than whether you have an LLC.

Do I need to put my SSN on the invoice?

Usually no. Invoices typically do not require a taxpayer ID number. If a client needs your tax information, they commonly request it on a W-9 form instead.

Can I charge tax on my invoice?

Only charge sales tax if it applies to what you sell and you’re compliant with the registration and filing requirements in the relevant jurisdiction. If you’re unsure, it’s worth checking the rules for your state and product/service type.

What’s the easiest way to stay organized for taxes?

Use consistent invoicing, keep receipts for expenses, and track income and payments in one place. Invoice24 helps by keeping a clean record of invoices, totals, due dates, and payment statuses.

Bottom line: yes, you can invoice without registering a business entity

For many people in the US, sending invoices does not require registering an LLC or corporation.

The most important part is not the business entity; it’s operating transparently, keeping good records, and handling taxes correctly.

If you’re ready to invoice professionally right now, invoice24 gives you everything you need to present polished invoices, define clear payment terms, track what’s been sent and paid, and maintain clean records as your work grows.
