Frequently Asked Questions

Do US freelancers need to charge sales tax?
Most states don't tax services, only physical goods. However, rules vary widely by state. Check your state's Department of Revenue for service taxability.
Do I need an EIN to invoice clients?
No. Sole proprietors can use their SSN. However, an EIN is recommended for privacy and professionalism — it's free from the IRS.
What information must a US invoice include?
There's no federal law mandating invoice format, but standard practice includes business info, client info, invoice number, dates, line items, subtotal, tax (if applicable), and total.
