Most US freelancers doing pure digital/service work never need to register for sales tax at all. Whether you do depends on nexus (a business connection to a state) and whether your state taxes your type of work — there's no single national threshold to track.
| Situation | Sales tax? | Invoice type |
|---|---|---|
| Digital/service-only, no nexus | No | Standard invoice — no tax line |
| Nexus + taxable work | Yes — register with the state | Invoice with sales tax shown separately |
| Unsure | Check first | Ask your state Dept. of Revenue |
Here's what a clean freelance invoice looks like for a designer whose work isn't taxable:
| Description | Amount |
|---|---|
| Brand identity design — logo + style guide | $950.00 |
| Social media template pack × 10 | $350.00 |
| Revisions — 2 rounds | $150.00 |
No sales tax line and no seller's permit number — correct for freelancers whose work isn't taxable in their state.
Every invoice needs a unique reference number. It's good practice for your own tax records. Here are the most common formats:
TradieNotes generates a unique reference number automatically for every invoice — one less thing to track.
The most common US freelance payment terms are Net 14 or Net 30 from invoice date. There's no single federal default the way some countries have, so always state your terms explicitly on the invoice or in your contract.
Always include your bank routing and account number directly on the invoice — making it easy to pay means getting paid faster. You can also add your own late-fee terms for overdue invoices, since there's no single federal default the way some countries have.

As a sole proprietor in the US you can start invoicing immediately — no state entity registration, no LLC, no accountant required to get going. You invoice under your own name (or a DBA, if your state requires one for a trading name), and your Social Security Number or a free EIN is what you'll use for tax purposes.
Here's exactly how to invoice as a sole proprietor in the US:
Most new freelancers and self-employed contractors in the US don't need to charge sales tax at all — that's perfectly normal, especially for digital/service-only work. A non-taxable invoice is simpler, but it still has requirements.
For self-employed invoicing in the US when sales tax doesn't apply:
| Mistake | Why it's a problem | What to do instead |
|---|---|---|
| Adding a sales tax line anyway | Confusing and technically incorrect if the work isn't taxable | Omit it entirely |
| Adding a seller's permit number | You don't have one if not registered | Leave it off |
| Collecting sales tax without a permit | A compliance problem — you can't collect tax you're not registered to collect | Register first, then charge |
You generally need to register for a seller's permit once you have nexus in a state and your work is taxable there — there's no single combined-income threshold to track. A freelance writer doing pure digital work across many states may never owe sales tax anywhere; a freelancer selling physical deliverables is more likely to.
If you're unsure whether your work is taxable in a given state, check with that state's Department of Revenue before you register or start charging — getting it wrong in either direction causes problems.
