What Is Sales Tax?
Sales tax is a single-stage consumption tax collected only once — at the point of final sale to the end consumer. When you buy a $50 shirt in a state with 7% sales tax, the retailer collects $3.50 and remits it to the state (and sometimes a local jurisdiction on top). Wholesalers, manufacturers, and distributors earlier in the supply chain generally don't pay sales tax on business inputs, because sales tax is designed to hit final consumption, not every transaction along the way.
In the US, sales tax is set at the state level (and often layered with county and city taxes), which is why the rate varies so much by location — and why five states charge no state sales tax at all: Alaska, Delaware, Montana, New Hampshire, and Oregon (sometimes remembered by the acronym "NOMAD"). Note that Alaska allows local sales taxes even without a state-level tax.
What Is VAT?
VAT (Value Added Tax), sometimes called GST (Goods and Services Tax) in countries like Canada, Australia, and India, is a multi-stage consumption tax collected at every step of production and distribution — not just at the final sale. Each business in the chain charges VAT on its output, but can reclaim (as a credit) the VAT it already paid on its inputs. The net effect: only the "value added" at each stage is actually taxed, and the full cumulative tax lands on the final consumer, who cannot reclaim anything.
More than 170 countries use a VAT or GST system, including the entire European Union, the United Kingdom, Canada, Australia, and most of Asia and Latin America. The United States is one of the few major economies that has never adopted a national VAT.
How VAT Actually Flows Through a Supply Chain
Here's a simplified example at a 20% VAT rate, following a wooden table from raw lumber to the store shelf:
| Stage | Sale Price (ex-VAT) | VAT Charged (20%) | VAT Credit Claimed | Net VAT Paid to Government |
|---|---|---|---|---|
| Lumber mill sells wood to furniture maker | $100 | $20 | $0 | $20 |
| Furniture maker sells table to retailer | $250 | $50 | $20 (paid on lumber) | $30 |
| Retailer sells table to consumer | $400 | $80 | $50 (paid on wholesale table) | $30 |
| Total VAT collected by government | $80 |
Notice that the total VAT collected across all three stages ($20 + $30 + $30 = $80) equals exactly what the final consumer pays on the $400 retail price (20% of $400 = $80). Each business only ever pays tax on the value it added — the lumber mill's raw material markup, the furniture maker's manufacturing markup, the retailer's distribution markup — while the consumer, who cannot reclaim VAT, absorbs the cumulative total.
Sales Tax vs VAT: Side by Side
| Feature | Sales Tax (US) | VAT (EU, UK, most of world) |
|---|---|---|
| Collection points | Once, at final retail sale | At every stage of production/distribution |
| Who remits it | The final retailer only | Every business in the chain (net of credits) |
| Displayed on price tags? | No — added at checkout in the US | Yes — prices are usually shown VAT-inclusive |
| Business-to-business sales | Generally exempt (resale certificates) | Taxed, then credited back via input VAT recovery |
| Rate-setting authority | State/local (no federal sales tax) | National government (sometimes with EU minimum rules) |
| Evasion risk | Higher — only one collection point to fail | Lower — self-policing via the credit-invoice chain |
| Paperwork burden on business | Lower for most retailers | Higher — every business tracks input and output VAT |
US Sales Tax Rates by Type of State
Combined state-plus-local sales tax rates in the US vary widely — commonly somewhere in the 0%–10% range depending on location, with average combined rates in most tax-charging states clustering in the mid-single digits. A few patterns worth knowing:
- No state sales tax: Alaska, Delaware, Montana, New Hampshire, Oregon.
- Local add-ons can matter more than the state rate: Some cities and counties layer 1–5 percentage points on top of the state rate, so the state rate alone doesn't tell the whole story.
- Groceries and prescription drugs are often exempt or taxed at a reduced rate in many states, while prepared restaurant food is usually fully taxed.
- Online purchases are generally taxed based on the buyer's shipping address following the 2018 South Dakota v. Wayfair Supreme Court decision, which allowed states to require out-of-state sellers to collect sales tax even without a physical presence in the state.
VAT Rates Around the World
| Region | Typical Standard VAT/GST Rate |
|---|---|
| United Kingdom | ~20% |
| European Union (varies by country) | ~19%–25% |
| Canada (federal GST + provincial) | ~5% GST, plus provincial tax (combined often 12–15%) |
| Australia (GST) | ~10% |
| Japan (consumption tax) | ~10% |
These are typical/illustrative standard rates — most VAT systems also have reduced rates (often 0–10%) for essentials like groceries, books, children's items, and certain medical goods, so the effective rate on any given purchase can be lower than the headline number. Always confirm current rates with the relevant national tax authority, since VAT rates are changed by legislation from time to time.
Why Doesn't the US Have a VAT?
The US Constitution reserves broad taxing power to the states, and sales tax evolved as a state-level tool starting in the 1930s. A national VAT would require an entirely new federal tax structure layered on top of (or replacing) existing state sales taxes — a politically difficult and administratively complex change that would affect every business and consumer simultaneously. Various VAT proposals have surfaced in US policy debates over the decades, but none has been enacted; the sales-tax-at-the-state-level model remains the US approach.
What This Means for You as a Shopper
In practice, both systems land on you as the final consumer — you pay tax either way. The differences that actually matter to shoppers:
- Sticker shock: US sales tax is added at checkout, so the price tag understates your total. VAT-inclusive pricing (common abroad) shows you the real final price up front.
- Tourist VAT refunds: Many VAT countries let non-resident tourists reclaim VAT on goods taken home — a benefit that doesn't exist with US sales tax, since sales tax isn't collected from foreign visitors any differently than locals.
- Cross-border shopping: When comparing a $400 US price to a €400 European price, remember the European price is very likely VAT-inclusive already, while the US price is not — always convert and adjust before assuming one is cheaper.
How Online Marketplaces Collect Tax
Since the 2018 South Dakota v. Wayfair Supreme Court decision, US states can require out-of-state and online sellers to collect sales tax based on the buyer's location, even without a physical store or warehouse in that state — a major shift from the pre-2018 rule that generally required a physical presence. Many states also have "marketplace facilitator" laws that shift the tax-collection responsibility onto large platforms (rather than each individual third-party seller), meaning the marketplace itself calculates and remits tax on behalf of sellers using its platform. In VAT countries, a similar shift has occurred: major online marketplaces are often required to collect and remit VAT on behalf of non-resident sellers shipping to consumers in that country, closing a gap that used to let some cross-border e-commerce escape VAT collection entirely.
Common Misconceptions
- "VAT means I pay tax multiple times on the same purchase." Not true for the end consumer — while VAT is collected at every stage, businesses reclaim what they paid via input credits, so only the final consumer bears the cumulative total once, embedded in the final price.
- "US businesses never pay tax on anything they buy." Not quite — resale exemptions apply to goods purchased specifically for resale, but businesses still pay sales tax on most operating purchases (office supplies, equipment, services) just like consumers do, since those purchases aren't for resale.
- "A country's VAT rate tells you the tax on everything you buy there." Not necessarily — most VAT systems apply reduced rates (sometimes 0%) to categories like groceries, books, children's clothing, and certain medical items, so the effective rate on any specific purchase can be well below the advertised standard rate.
