One invoice, two opposite meanings
A receipt with no VAT on it can mean two entirely different things, and the receipt does not tell you which.
Zero-rated means the supply is taxable, at a rate of nil. The supplier charges nothing and reclaims all the VAT on its own costs.
Exempt means the supply is outside the tax. The supplier charges nothing and reclaims nothing — that VAT stays in its costs, and comes back out in its prices.
The customer sees the same thing. The supplier is in opposite positions.
| Zero-rated | Exempt | |
|---|---|---|
| Tax on the sale | none | none |
| Input tax on costs | fully recoverable | not recoverable |
| Counts towards registration | yes | no |
| Typical examples | exports, international transport | financial services, residential lets |
Before you read on
Two businesses both charge no VAT to their customers — one makes zero-rated supplies, the other exempt ones. Which is better off?
The zero-rated one, and often by a lot. A zero-rated supply is taxable at nil, so the VAT on everything the business buys is fully recoverable. An exempt supply is outside the charge, so that VAT is lost and stays in the business's costs. Both print nothing on the invoice, which is exactly why the difference gets missed until a return is filed.
Why that difference is worth real money
A developer building a new home reclaims the VAT on bricks, labour and machinery, because the first sale of a new dwelling is zero-rated in many systems. A landlord letting that same home reclaims nothing, because a residential letting is exempt. Same building, same country, opposite treatment, and it turns on which transaction is happening.
It also decides whether a business needs to register at all. Exempt supplies do not count towards a registration threshold, so a business making only exempt supplies can be well past the figure and correctly unregistered.
Reduced rates are lists, not principles
The third mechanism is a genuine rate, below the standard one. Every VAT system with reduced rates arrived at them the same way — item by item, over decades.
Spain taxes bread, milk, cheese, eggs, fruit and vegetables at 4%, and other food at 10%. Switzerland taxes a hotel bed at 3.8% and the dinner served in the same hotel at 8.1%. France has four rates, one of them 2.1%, which applies to reimbursable medicines and to the licence fee. Austria calls both 13% and 10% ermäßigter Steuersatz, so a single country has two different rates under one name.
None of that follows from a principle about necessity. It follows from what was negotiated and when. The only reliable way to know which rate applies is to look it up, which is why every country tool here links its rates to the statute rather than describing them.
The systems with no reduced rate at all
Not every country has this problem, and the ones that do not are instructive.
The UAE and Saudi Arabia have exactly two positions: standard, or zero-rated. Mexico has 16%, an 8% border stimulus and zero, with nothing in between. In these systems the entire difficulty moves from “which rate” to “which category”, and the arithmetic becomes trivial while the classification stays just as hard.
That is the general shape. A VAT system’s complexity is not in its arithmetic. Every one of these is the same multiplication. It is in the lists.
What changes, and how often
Rates move, and they move on a date rather than on an invoice.
Saudi Arabia tripled its rate on 1 July 2020. Switzerland raised all three of its rates on 1 January 2024 to fund old-age insurance. Iran went from 9% to 10% in 2024. Mexico’s 8% border figure is not a rate at all but a stimulus granted by decree, currently authorised only to 31 December 2026.
In every case the rate is decided by when the supply happened, not when the invoice was raised or paid. An old invoice at an old rate is correct, and reworking it at today’s rate is the error.
Common questions
What is the difference between zero-rated and exempt?
A zero-rated supply is taxable at a rate of 0%, so no tax is charged and the input tax on making it is fully recoverable. An exempt supply is outside the charge altogether, so no tax is charged and the input tax is lost. Both print nothing on the invoice. For the supplier they are opposites, and the difference is often worth more than the tax itself.
Why do reduced rates cover such strange lists of things?
Because they are lists, not principles. Each one is the outcome of decades of lobbying, judicial decisions and political compromise, written into statute item by item. That is why something that sounds obviously essential often sits at the standard rate while something that does not sits at the reduced one, and why no rule of thumb predicts them.
Does a lower rate mean the customer pays less?
For a zero or reduced rate, generally yes — the tax is lower and prices follow, though not always fully. For an exemption it is less clear: the exempt supplier cannot reclaim the VAT on its own costs, so that tax is buried in its prices instead. An exemption can leave a customer paying more than a zero rate would.
Can a business choose to be exempt?
Almost never. Exemption attaches to the supply rather than to the business, and it is compulsory where it applies. Some systems allow an option to tax certain supplies — commercial property is the common case — precisely because being exempt is often the worse position and businesses want out of it.
