How to Invoice as a US Freelancer in 2026

If you are a freelancer in the United States, invoicing is simpler than in Europe — there is no VAT, no mandatory e-invoicing, and no government-prescribed format. But there are still rules you need to follow to stay compliant with the IRS and get paid on time.

What to Include on a US Freelance Invoice

Every invoice you send should have these fields:

• Your full legal name or business name (as registered with the IRS)
• Your address (city, state, ZIP)
• Your EIN or SSN (only if the client requests it for 1099 reporting — many freelancers use an EIN to avoid sharing their SSN)
• Client’s name and address
• Unique invoice number (sequential: INV-2026-001, INV-2026-002)
• Invoice date and due date
• Itemized list of services with descriptions, quantities, rates, and totals
• Total amount due in USD
• Payment terms (Net 15, Net 30, Due on receipt)
• Payment instructions (bank account, Zelle, PayPal, Wise, check)

The 1099-NEC Rule

If a single client pays you $600 or more in a calendar year, they are required to file Form 1099-NEC with the IRS. This means:

• Clients may ask you to fill out a W-9 form before your first invoice
• You should keep track of total payments per client per year
• You do not need to add any special 1099 reference on your invoices — it is the client’s responsibility to file

Do US Freelancers Need to Charge Sales Tax?

In most states, freelance services are not subject to sales tax. This includes consulting, design, software development, writing, marketing, and most professional services.

However, some states do tax certain services. If you sell physical products, digital goods, or SaaS subscriptions, you may need to collect sales tax depending on the state. Five states have no sales tax at all: Oregon, Montana, Delaware, New Hampshire, and Alaska (no state tax, but some local taxes).

Estimated Tax Payments

As a freelancer, you are responsible for paying your own income tax and self-employment tax (Social Security + Medicare = 15.3%). The IRS expects you to make quarterly estimated tax payments if you expect to owe $1,000 or more:

• Q1: April 15
• Q2: June 15
• Q3: September 15
• Q4: January 15 (of the following year)

Payment Terms for US Freelancers

The most common payment terms in the US:

• Due on receipt — payment expected immediately (common for small projects)
• Net 15 — payment due within 15 days (standard for ongoing clients)
• Net 30 — payment due within 30 days (standard for corporate clients)
• 50/50 — 50% upfront, 50% on delivery (common for larger projects)
