Self-Employed Invoice Guide — Everything Freelancers Need to Know.

You are your own billing department

As a self-employed freelancer, contractor, or consultant, you wear every hat — including the billing hat. No one else sends your invoices, follows up on late payments, or organizes your records. Getting invoicing right is not just about getting paid. It is about taxes, professionalism, and protecting your business.

What to put on a self-employed invoice

Your invoice needs to serve both your client (who needs to know what to pay) and the IRS (who needs a record of your income). Here is what every self-employed invoice should include:

1. Your name or DBA — The name the client knows you by and the name on your tax return. If you have an EIN, include it optionally.
2. Your contact information — Email and phone at minimum. Mailing address if you expect checks.
3. Client's name and contact — Who you are billing and where to send the invoice.
4. Invoice number — Sequential and unique. This is critical for organizing income at tax time.
5. Dates — Issue date and due date. Clear payment terms reduce confusion.
6. Description of work — Be specific. "Website redesign — 15 hours at $85/hr" is better than "Web work."
7. Line item totals — Each service or product with its price.
8. Subtotal, tax, total — Clear breakdown so the client knows exactly what they are paying.
9. Payment methods — Bank transfer details, payment link, or other accepted methods.
10. Notes or terms — Late fee policy, thank-you message, or project reference.

Do you need an EIN or LLC to invoice?

No. You can invoice as a sole proprietor using your Social Security Number (SSN) for tax purposes. You do not need an LLC, corporation, or Employer Identification Number (EIN) to send an invoice or get paid.

However, there are good reasons to get an EIN (free from the IRS) and form an LLC:

• An EIN lets you avoid sharing your SSN with clients who issue 1099s
• An LLC separates your personal assets from business liabilities
• Both signal professionalism to larger clients

For most freelancers starting out, invoicing under your own name as a sole proprietor is perfectly fine.

Sales tax for the self-employed

Sales tax rules vary wildly by state and service type. Some general guidelines:

• Services are often not taxed — But some states (like New Mexico, Hawaii, South Dakota) tax most services.
• Physical products are usually taxed — If you sell goods alongside your services, those goods may be taxable.
• Digital products are a gray area — Some states tax downloadable products, others do not.

Set your default sales tax rate in your invoice tool and edit it per invoice when needed. SpeakBill saves your tax rate and applies it automatically with the option to override on any invoice.

Quarterly taxes and invoice records

As a self-employed person, the IRS expects you to pay estimated taxes four times a year (April, June, September, January). Your invoice records are the foundation of your income reporting:

• Each invoice documents a specific amount of revenue
• Mark invoices as "Paid" when you receive payment
• At tax time, your paid invoice total should match your reported income

Set aside 25-30% of every invoice payment for taxes. It is better to have too much saved than to face a surprise tax bill in April.
