Does the USA Have GST? How to Invoice US Clients

Short answer: no, the United States doesn't have GST. There's no federal goods-and-services tax, no VAT, and no national tax registration number like a GSTIN. What the US has instead is sales tax — a completely different system, set independently by each state, that in most cases doesn't apply to your invoice at all if you're a freelancer or business outside the US billing a US client for services.

What does the US have instead of GST?

GST and VAT are multi-stage taxes — a percentage is added and reconciled at every step of a supply chain, from raw material to manufacturer to retailer, with businesses claiming input credit along the way (the same mechanic covered in our Input Tax Credit guide). US sales tax is a single-stage tax: it's charged once, by a retailer, to the final consumer, at whatever rate that particular state (and sometimes county or city) sets. Rates commonly range from around 0% in a few states to over 9% in others, there's no federal rate at all, and — unlike GST — there's no national portal or single registration number, since each state runs its own system.

Do I need to charge US sales tax as a foreign freelancer?

In the ordinary case, no. Sales tax is only owed by a seller who has nexus — a legal connection — with a given state:

• Physical nexus — an office, warehouse, employee or other physical presence in that state.
• Economic nexus — crossing a state-set sales or transaction-count threshold there, commonly around $100,000 in annual sales or 200 transactions, following the 2018 South Dakota v. Wayfair Supreme Court ruling that let states tax remote sellers without a physical presence.

A freelancer or small business based in India, invoicing a US client for services with no US office and no sales volume anywhere near that threshold, has no nexus in any state — and with no nexus, there's no sales tax to collect or remit. The practical result: leave the tax field on your invoice blank, the same way you would for any other export of services, rather than guessing at a rate or adding a "GST" line that doesn't exist in the US system at all.

What should your invoice show instead of a tax line?

On the Indian side, this is still an export of services — the same zero-rated GST treatment described in our invoicing international clients guide applies, meaning you also don't charge Indian GST on this invoice (typically under an LUT, covered in our LUT & export of services guide). So a compliant invoice to a US client usually carries no tax line from either country's system — not because of some special US exemption, but because neither country's tax actually applies to this specific transaction.

When would US sales tax actually apply?

Sales tax becomes relevant mainly if you build up genuine nexus in a US state — for example, hiring US-based staff, opening a US office, or scaling e-commerce sales to US consumers past a state's economic nexus threshold. It can also apply differently depending on what's being sold: physical goods shipped into the US are more commonly taxable than professional services, and taxability of digital products/services varies significantly state by state. These are genuine edge cases outside a typical freelance-services invoice, and worth checking with a tax professional familiar with US state tax if they apply to you — the IRS itself doesn't prescribe an invoice format or a sales tax rate, since sales tax isn't a federal tax at all.

Worked example

QWIK INVOICE's international invoice generator and the Standard format inside the main app are set up exactly for this case — a Tax ID field instead of a GSTIN, USD (or any currency) instead of INR, and no forced tax line. You still need to confirm your own India-side LUT/export status separately, but the invoice itself is ready to send.
