If you sell to clients in different countries — or you've just moved your freelance business abroad — you've probably noticed that every country seems to call its consumption tax something different. Americans talk about sales tax, Europeans about VAT, and Australians and Indians about GST. Are they the same thing with different names? Not quite.
This guide explains how each system actually works, which countries use which, and — most practically — what your invoice needs to show depending on where you and your customer are.
The Three Systems at a Glance
| Feature | Sales Tax | VAT (Value-Added Tax) | GST (Goods & Services Tax) |
|---|---|---|---|
| Charged when | Only at the final sale to the consumer | At every stage of the supply chain | At every stage of the supply chain |
| Who bears it | The final consumer | The final consumer (businesses reclaim it) | The final consumer (businesses claim credits) |
| Business purchases | Often exempt with a resale certificate | Input VAT is deducted from output VAT | Input tax credit (ITC) offsets tax collected |
| Typical rates | 0–11% (varies by state/city) | 5–27% | 5–28% (India has multiple slabs) |
| Where used | United States | EU, UK, Nepal, most of the world | India, Australia, NZ, Canada, Singapore |
The key insight: VAT and GST are essentially the same mechanism under different names — a multi-stage tax where businesses collect tax on sales and reclaim tax on purchases. US-style sales tax is genuinely different: it's collected only once, at the final retail sale.
How Sales Tax Works (United States)
The United States has no national consumption tax. Instead, each state sets its own sales tax, and cities and counties can add local rates on top. Combined rates range from 0% (Delaware, Oregon, Montana, New Hampshire) to over 10% in parts of Louisiana and Tennessee.
- Tax applies only to the final sale to the end consumer.
- Business-to-business sales for resale are typically exempt — the buyer provides a resale certificate.
- Most B2B services (including freelance work like design or development) are not taxed in many states — but rules vary widely.
- Since the South Dakota v. Wayfair ruling, out-of-state sellers may owe sales tax where their customers live once they cross economic thresholds.
What a US invoice shows
A subtotal, a "Sales Tax" line with the applicable combined rate (if any), and the total. There's no tax registration number requirement like VAT/GST countries have, though including your EIN for B2B clients is common practice.
How VAT Works (EU, UK, Nepal, and Most of the World)
Value-Added Tax is used by more than 160 countries. Every business in the chain charges VAT on its sales (output VAT) and reclaims the VAT it paid on purchases (input VAT). The difference is remitted to the tax authority — so the tax effectively lands only on the final consumer, but it's collected in small pieces along the way.
- European Union — each member state sets its own standard rate (17%–27%; e.g., Germany 19%, France 20%, Hungary 27%), with reduced rates for essentials. Cross-border B2B sales within the EU often use the reverse charge: you invoice at 0% and the buyer self-accounts for VAT.
- United Kingdom — standard rate 20%; registration required above the turnover threshold.
- Nepal — standard rate 13%; VAT-registered businesses must show their VAT number on every tax invoice.
- Gulf states — the UAE and Saudi Arabia introduced VAT recently (UAE 5%, KSA 15%).
What a VAT invoice must show
- The word "Invoice" (or "Tax Invoice"), a unique sequential number, and the issue date
- Your business name, address, and VAT registration number
- The customer's name and address (and their VAT number for B2B/reverse-charge sales)
- A per-line breakdown, the VAT rate applied, the net amount, the VAT amount, and the gross total
How GST Works (India, Australia, Canada, and Others)
GST is mechanically the same as VAT — a multi-stage tax with input credits — but the implementations differ by country:
- India — multiple slabs (commonly 5%, 12%, 18%, 28%). Domestic sales split the tax into CGST + SGST (intra-state) or charge IGST (inter-state). Invoices must show your GSTIN, the buyer's GSTIN for B2B, HSN/SAC codes, and the tax split.
- Australia — a single flat 10% GST. Registered businesses issue "Tax Invoices" showing their ABN. Registration is mandatory above A$75,000 turnover.
- New Zealand — flat 15% GST.
- Canada — 5% federal GST, with most provinces adding PST or merging into HST (13–15% in the eastern provinces). Quebec runs its own QST.
- Singapore — 9% GST (from 2024).

Practical Rules of Thumb
- Label the tax the way your country does. An Australian client expects "GST 10%", a UK client expects "VAT 20%", a Texan client expects "Sales Tax 8.25%". Using the wrong label looks careless and can cause bookkeeping confusion on the client's side.
- Show your registration number if you're VAT/GST registered — in most of these countries it's legally required on tax invoices.
- Exports are usually zero-rated. If you're a Nepali or Indian freelancer invoicing a US client, your service is typically an export — check whether you should charge 0% rather than your domestic rate.
- Below the registration threshold? Then in most VAT/GST countries you simply don't charge the tax at all — don't add it "just in case".
