1099 Invoice Guide: How to Invoice as an Independent Contractor

What people mean by a "1099 invoice"

The invoice is your own document: it asks the client to pay for work you did as someone who is not their employee. The name comes from Form 1099-NEC, the information return a business client may file about what it paid you. Three documents, three different jobs:

Sources: IRS, About Form W-9; Instructions for Forms 1099-MISC and 1099-NEC (Rev. 12/2026). On the W-9 row, the form's own instructions say "Do not send to the IRS" at the top of the form (Form W-9).

Form W-9: your taxpayer ID for the client

"Use Form W-9 to provide your correct Taxpayer Identification Number (TIN) to the person who is required to file an information return with the IRS to report, for example: Income paid to you."

• SSN or EIN. The form's instructions: "If you are a sole proprietor and you have an EIN, you may enter either your SSN or EIN." (Form W-9, Rev. March 2024). The IRS defines a sole proprietor as "someone who owns an unincorporated business by themselves" (Sole proprietorships).
• Do you need an EIN? The IRS lists, among others: "You need an EIN if you: Have employees; Will need to pay employment, excise or alcohol, tobacco, and firearms taxes; Withhold taxes on income, other than wages, paid to a non-resident alien". It adds: "If you don't need an EIN for federal tax purposes, you can still request one for banking or state tax purposes." (Employer identification number)
• If the TIN is missing or wrong. "There are situations when the payer is required to withhold at the current rate of 24 percent." Backup withholding may be required "because you failed to provide a correct taxpayer identification number (TIN) to the payer for reporting on the required information return." (IRS, Backup withholding, last reviewed 28 June 2026)

When the client files Form 1099-NEC

"File Form 1099-NEC, Nonemployee Compensation, for each person in the course of your business during the year to whom you have paid at least $2,000 in: Services performed by someone who is not your employee (including parts and materials) (box 1a); or Payments to an attorney (box 1a)."

• Which payments: the $2,000 figure is for payments made in 2026. What's New: "For tax years beginning after 2025, the minimum threshold amount for reporting certain payments … increased to $2,000 and may be adjusted for inflation beginning in calendar year 2027."
• When: "You are required to furnish the payee statements and file with the IRS by January 31." This revision is the one the IRS says to use for 2026 information filed in early 2027.
• Who files: the payer, not you. You receive a copy; your invoices and payment records are how you check that its figure matches what you were paid.

How to invoice as an independent contractor, step by step

Each step names the field in the free Freelance Invoice Generator; the same fields are on the blank templates above.

1. Put your own details at the top. In the From block enter your name or business name, your address, email and phone. If you trade under a business name, use the name your client has on your Form W-9.
2. Add the client you are billing. In the Bill to block enter the client's company name and billing address, and the accounts-payable email if they gave you one.
3. Number and date the invoice. Give it a unique Invoice # that you have not used before, the invoice Date, and a Due Date that matches your agreed payment terms.
4. List the work. One line per service or milestone: a description, the unit (Hour, Day, Project), the quantity and the unit price. The generator multiplies and totals the lines.
5. Add references the client asked for. If the client gave you a purchase order, contract or project number, put it in the Notes or in the line description so their accounts-payable team can match the invoice.
6. Set tax, deposit and totals. Leave the tax rate at 0 unless you are required to charge sales tax; at 0 no tax line prints. If the client paid a deposit, enter it in Deposit Paid and the PDF shows the Balance Due.
7. State payment terms and how to pay. Write your payment terms in Terms & Conditions and add each payment method (bank transfer, payment link) with its details.
8. Download and send the PDF. Click Preview & Download, check the preview, then Confirm & Download PDF. Send it to the person or address the client named for invoices, and keep a copy.

Need a number format? The invoice number generator builds one. The payment due date calculator turns terms like Net 30 into a date, and the late fee calculator shows what your state allows before you write a late-fee clause.

The generator is free and unmetered for normal use; an anti-abuse cap of 20 PDFs per device per day (200 per IP) applies, well above ordinary use, and the blank template downloads on this page are not metered. A one-line "Created free with myinvoicetemplate.com" credit is switched on by default and one free checkbox in the settings turns it off. Your draft is stored in your own browser on this device, so download and keep the PDF you need.

What an independent contractor invoice usually includes

For private-sector clients, the content comes from common practice plus whatever your contract and the client's accounts-payable instructions ask for. A typical invoice carries:

• your name or business name, address and contact details;
• the client's name and billing address;
• a unique invoice number and the invoice date;
• the purchase order, contract or project reference, if the client gave you one;
• a description of the services with hours or quantities, rates and amounts;
• the total due, the payment terms or due date, and how to pay.

Billing a US federal agency

Federal contracts that include the Prompt Payment clause set out a "proper invoice". FAR 52.232-25(a)(3): "A proper invoice must include the items listed in paragraphs (a)(3)(i) through (a)(3)(x) of this clause." Those items are:

1. "Name and address of the Contractor."
2. "Invoice date and invoice number." The clause adds: "The Contractor should date invoices as close as possible to the date of the mailing or transmission."
3. "Contract number or other authorization for supplies delivered or services performed (including order number and line item number)."
4. "Description, quantity, unit of measure, unit price, and extended price of supplies delivered or services performed."
5. "Shipping and payment terms (e.g., shipment number and date of shipment, discount for prompt payment terms)."
6. "Name and address of Contractor official to whom payment is to be sent (must be the same as that in the contract or in a proper notice of assignment)."
7. "Name (where practicable), title, phone number, and mailing address of person to notify in the event of a defective invoice."
8. "Taxpayer Identification Number (TIN). The Contractor shall include its TIN on the invoice only if required elsewhere in this contract."
9. "Electronic funds transfer (EFT) banking information." On the invoice "only if required elsewhere in this contract"; otherwise the contractor must have submitted correct EFT information as the contract or agency procedures require.
10. "Any other information or documentation required by the contract (e.g., evidence of shipment)."

Source: FAR 52.232-25, Prompt Payment (acquisition.gov, retrieved 2026-09-25). An invoice that does not comply is returned "within 7 days after receipt" (shorter for some perishable goods).

Example: an annotated contractor invoice

Names are placeholders and the amounts are illustrative, not market rates.

1. A. Your name. Use the same name and business name as on the Form W-9 you gave this client; the payer asks for your TIN on that form.
2. B. The client's reference. A purchase order, contract or project number lets accounts payable match the invoice. On the freelance blank it fits the Project / period box; in the generator, use the Notes or the line description.
3. C. No tax line. The tax rate is left at 0 here, so the PDF shows no tax line. Whether you must charge sales tax is a question for your state's tax agency.
4. D. Terms. A due date and your payment methods, so nobody has to ask.

Card and payment-app payments: Form 1099-K, not 1099-NEC

"Payments made with a credit card or payment card and certain other types of payments, including third-party network transactions, must be reported on Form 1099-K … and are not subject to reporting on Form 1099-MISC or Form 1099-NEC."

The threshold for payment apps and online marketplaces, as the IRS states it: they "are required to report payments on Form 1099-K when the total amount of payments you receive for goods or services through the platform exceeds $20,000 in more than 200 transactions." The same page: "You may receive a Form 1099-K even when total payments or transactions are less than the reporting threshold." (IRS, Understanding your Form 1099-K, last reviewed 28 June 2026)

Taxes the invoice does not settle

The IRS says the business paying you "doesn’t generally withhold taxes from these types of payments, as it is assumed you will report and pay taxes on this income when you file your federal income tax return" (Backup withholding). Two IRS rules then apply to you directly:

• Self-employment tax. "You usually must pay self-employment tax if you had net earnings from self-employment of $400 or more." The rate "consists of 12.4% for Social Security and 2.9% for Medicare taxes." (IRS Topic no. 554)
• Estimated tax. The 2026 Form 1040-ES lists four payment dates: April 15, 2026; June 15, 2026; Sept. 15, 2026; and Jan. 15, 2027. Its footnote: "You don’t have to make the payment due January 15, 2027, if you file your 2026 tax return by February 1, 2027, and pay the entire balance due with your return." (Form 1040-ES (2026))
