The IRS does not prescribe what an invoice must show. It asks for records that clearly show income and expenses, and names invoices among the supporting documents.

### What tax rate does the United States preset use?

There is no federal sales tax. Each state sets its own, and cities and counties often add to it, so enter the combined rate where you sell, or leave it at 0.

Yes. The preset bills in USD; type any three-letter currency code to change it.

### Do I send a W-9 with my invoice?

Only if the client asks. A client who must report what it paid you to the IRS on an information return will ask for Form W-9, which gives them your correct taxpayer identification number. It goes to the client, not on the invoice.

### How long do I keep invoices in the United States?

Generally 3 years; 6 years if unreported income exceeds 25% of gross income shown; 7 years for worthless securities/bad debt deduction claims; employment tax records at least 4 years.
