Standard VAT / GST / Sales-Tax Rate by Country (2026)
The reverse-VAT math (divide by 1 + rate) is identical in every country — only the rate changes.
| Country | Tax name | Standard rate | To remove from a tax-included price, divide by | To add to a net price, multiply by |
|---|---|---|---|---|
| United Kingdom | VAT | 20% | 1.20 | 1.20 |

| France | VAT (TVA) | 20% | 1.20 | 1.20 |
| Spain | VAT (IVA) | 21% | 1.21 | 1.21 |
| Italy | VAT (IVA) | 22% | 1.22 | 1.22 |
| Ireland | VAT | 23% | 1.23 | 1.23 |
| Argentina | VAT (IVA) | 21% | 1.21 | 1.21 |
| Mexico | VAT (IVA) | 16% | 1.16 | 1.16 |

Standard (general) rate only; most countries also apply reduced rates to food, medicine and books. Canada adds provincial sales tax (PST/HST) on top of the 5% federal GST, for a combined 5–15% depending on province. India (GST 5–28%, general 18%) and China (6/9/13%) use multiple rates by category.

Standard vs Reduced / Super-Reduced VAT Rates (2026)
| Country | Standard | Reduced rate(s) | Typical reduced-rate items |
|---|---|---|---|
| Argentina | 21% | 10.5% (and 27% higher) | Housing construction, livestock sales, bank financing (10.5%); books, bread, milk, medicines, local passenger transport are VAT-exempt (0%) |
| United Kingdom | 20% | 5% / 0% (zero-rated) | Domestic fuel 5%; most food, books, children's clothes 0% |
| Germany | 19% | 7% | Food, books, newspapers, public transport, hotels |
| France | 20% | 10% / 5.5% / 2.1% | Restaurants & transport 10%; food & books 5.5%; medicines & press 2.1% |
| Spain | 21% | 10% / 4% | Hospitality & transport 10%; essential food, books, medicines 4% |
| Italy | 22% | 10% / 5% / 4% | Hospitality & energy 10%; basic food & books 4% |
| Mexico | 16% | 0% (northern border 8%) | Basic food, medicines, books (0%); northern border zone transactions 8% |
| Australia (GST) | 10% | 0% | Basic food, health, education (GST-free) |
| Canada (GST) | 5% | 0% | Basic groceries, prescription drugs, medical devices (0%) |
Reduced and super-reduced rates apply to essentials (food, medicine, books, children's items) as a social-policy measure; "0% / zero-rated" means no tax is charged but the seller can still reclaim input VAT (different from "exempt"). In Argentina, basic food (bread, milk), books, medicines and local passenger transport are VAT-exempt (not subject to the 10.5% reduced rate); the 10.5% rate applies to housing construction, livestock, and bank financing, while the 27% higher rate applies to utility services (telecoms, gas, water, energy) supplied to non-residential users. The reverse-VAT formula is the same at any rate — to strip 5.5% French VAT, divide by 1.055. Always confirm the exact rate for your specific product, since category rules vary.

Formulas
Remove Tax from a Tax-Included Price
net = price_with_tax / (1 + rate/100)
tax = price_with_tax - netAdd Tax to a Net Price
total = net_price x (1 + rate/100)
tax = total - net_priceThe Most Common Mistake
People often try to extract tax by multiplying the total by the rate. This is wrong.
Example with 21% VAT and a $121 total:
The rate is applied to the net price, not the total. To reverse-engineer from the total, you must divide by (1 + rate), not multiply by the rate.
Business vs Consumer Perspective
Tax Credits (for Businesses)
If you're VAT-registered, the tax you pay on business purchases (input tax) is deducted from the tax you charge on sales (output tax). You only remit the net difference to the tax authority.
Tax payable = Output tax (on sales) - Input tax (on purchases)If your input tax exceeds your output tax, you carry the balance forward.
Common Mistakes
1. Multiplying the total by the tax rate to find tax: this overestimates the tax. Always divide the total by (1 + rate).
2. Comparing tax-included prices with net prices: always convert to the same basis before comparing suppliers.
3. Calculating profit margin on tax-included prices: margin should be on net prices -- the tax isn't yours to keep.
4. Forgetting that not all products have the same rate: food, medicine, and basic goods often have reduced rates.
Example: Remove 21% VAT from $121,000
121,000 / 1.21 = $100,000.121,000 - 100,000 = $21,000.100,000 x 1.21 = 121,000 confirmed.Frequently asked questions
