VAT taxes every supply chain link, ultimately paid by consumers

VAT increases costs at every link in the chain until it reaches the consumer

How many times does the same euro pay VAT before leaving your account? As many stages as companies touch the product. A car doesn't come from one factory, but hundreds: dashboard, tires, shock absorbers, wiring, screws. The same applies to a washing machine, a TV, or a tomato. Each link invoices with VAT and settles its difference with the tax authority (Hacienda). In the end, the buyer pays 21% on the final price, and that visible rate is just the last layer of the onion.

What is paid at each link in the chain

The starting thesis is that the consumer bears hundreds or thousands of VAT settlements throughout a product's life. From the component manufacturer to transport, cold storage, distribution, and sale. In food, the phenomenon repeats with lower rates and narrower margins: from field to kitchen there is collection, cooling, transport, and handling, and each step drags its invoice along.

From this arise two broad claims. One: the State collects more through VAT, in many cases, than the entire product traceability costs. Two: a considerable state apparatus would be maintained solely with VAT. These are not closed figures, but urgent estimates, and should be treated as such.

What VAT payable reveals about each company's margin

Here the narrative splits in two. The mechanics are known: the company bears VAT on purchases, deducts it, and charges VAT on sales. If charged exceeds borne, they remit the difference. The example used is clean: with a margin of €100,000, VAT payable amounts to €21,000; with a margin of €10,000, to €2,100.

This implies that VAT payable measures the value added in the operation. The only one who cannot deduct anything is the final consumer: they pay the full 21%, and the entire chain has passed it forward until it lands on their bill. Those defending the tax add a nuance rarely cited: VAT replaced the old ITE (General Sales Tax), which taxed each transaction on its gross amount, meaning longer value chains paid more times. Under this prism, today's VAT would be more neutral than its predecessor. The step-by-step breakdown of how it is offset in each invoice is what gives or takes reason to each side.

Is VAT double taxation alongside corporate tax?

Technically no, although the argument circulates strongly. Those claiming otherwise argue that a company is taxed twice for the same profit: the 21% VAT on value added and around 25% corporate tax on earnings. The reply is that VAT is not deducted from the entrepreneur's profits, but comes from sales to customers, so the company acts merely as an intermediary.

Double taxation is accepted in wealth tax: it taxes savings that had already paid taxes when generated. Inflation eats away at the same ground in the background. Inheritance tax and income tax (IRPF) also appear on this list, noted as the biggest penalty for savers.

VAT applied on top of other taxes

The electricity bill is the recurring case: consumption, various taxes, and special taxes are summed up, and 21% VAT is applied to that total, which is already taxed. Even the digital levy appears subject to that same percentage. In housing, the rate moves between 6% and 10% on high-priced assets, forcing more saving and pushing some sellers to raise prices to recover it. In the Canary Islands, the equivalent figure, IGIC, stands at 7%.

• General VAT: 21%
• VAT on housing: 6% to 10%
• IGIC in Canary Islands: 7%
• Corporate tax: around 25%

Self-employed turned into free collectors

The cost is not just the rate. You must invoice, declare, and settle every quarter, a procedure unrelated to activity that forces payment for accounting services. If VAT is negative, it is booked against a period of up to five years for compensation. And there are expenses whose VAT cannot be deducted, such as fuel: there the business owner ends up paying the bill too.

It remains open whether raising VAT passed to the final price sinks sales. One school holds that the price including tax conditions demand; another replies that in goods like cars, clothes, or housing there is more demand than supply, and that a company doesn't sell because nobody wants its product, not because VAT makes it expensive. The disagreement was never settled.

How much does the State really cost?

The figure closing the account is public spending, around 50% of GDP, financed by citizens in one way or another. And the most aggressive calculation circulating assures that, without taxes, the prices of things would drop by 50%.

With these numbers, the question is not how much is paid, but how many times. The system is so efficient that it collects the tax several times for the same good and leaves the last in line with the task of being unable to deduct anything.
