The Spanish VAT equivalence surcharge, and who it lands on

The short answer

The equivalence surcharge is a compulsory special VAT scheme for Spanish retailers who are individuals, or a comunidad de bienes whose members are all individuals.¹ Their supplier adds an extra percentage to the invoice on the same base as the VAT⁶ and pays it to the tax agency on their behalf. In exchange, the retailer files no form 303, settles no tax on their sales and keeps no VAT ledgers.³

What is almost never said is the price: that surcharge is not deductible and cannot be charged to the customer.³ It comes out of the shop's margin.

The four rates, and why none has moved in fourteen years

Article 161 of the VAT Act sets four rates, and none has needed touching since the current wording took effect on 1 September 2012.⁶

The surcharge has no base of its own: article 160 says that «the taxable base of the equivalence surcharge shall be the same as the one that results for Value Added Tax».⁶ Both percentages apply to the same number and are added on the same invoice.

Which VAT rate a product carries is a matter for article 91 and not for this scheme, and there have been recent changes there: olive oils dropped to 4% in 2025. The surcharge follows them automatically, because article 161 refers to paragraphs Uno and Dos of article 91 rather than naming products.

The divisor is not 1.21

This is the costliest and quietest mistake in the whole scheme. Whoever receives an invoice with the surcharge and wants the base usually divides the total by 1.21, which is what they would do with any other invoice. But a total carrying the surcharge in the standard band holds 26.2 points, not 21.

On a €1,262.00 invoice:

Nearly €43 too much per thousand, and the wrong number is perfectly plausible, so nothing warns you. That gap then flows into the books and into the profit declared for income tax.

Who is in it, and why two identical shops can fall on opposite sides

Article 148.Uno reserves the scheme to individuals and to income-attribution entities.¹ Article 156.1.º says the same from the supplier's side, which charges the surcharge on supplies to retailers «that are not commercial companies».⁵ An SL with a shop on the high street is in the normal scheme because of its legal form and for no other reason.

With a comunidad de bienes the rule is finer than it looks, and it sits in the second paragraph of article 59.1 of the Regulation: such an entity qualifies «when all its partners, heirs, co-owners or participants are individuals».⁷ Two of them, identical in trade, in size and in product, fall on opposite sides if one has a company among its members.

Then there is the article 149 condition, which asks two things at once: selling goods without putting them through any process of manufacturing, elaboration or processing, and more than 80% of those sales going to someone who is neither a business nor a professional.² Whoever transforms what they sell stops being a retailer for what they transformed, while remaining one for the rest of their range.

Fifteen articles the scheme will not take

Article 59.2 of the Regulation closes the scheme for fifteen categories,⁷ and the list is wider than almost anyone remembers:

• motor vehicles, trailers, boats and aircraft, and their accessories and spare parts;
• jewellery, precious stones and objects of gold or platinum, except plating under 35 microns;
• garments of luxury fur, with a list of animals that runs half the article;
• original works of art, antiques and collectors' items;
• goods already used before their transfer, which takes out the entire second-hand trade;
• poultry and beekeeping equipment and its accessories;
• petroleum products subject to excise duty;
• machinery for industrial use;
• materials for building construction or development;
• minerals other than coal, and unmanufactured metals;
• the investment gold of article 140 of the Act.

To those add article 157, which removes the surcharge in four further situations even though the buyer is in the scheme. The most everyday one: goods the retailer is not going to resell. The counter, the till and the shop's computer are bought with ordinary VAT.

When it pays: the break-even margin

This is the question actually asked by anyone who can choose their legal form, and it is answered by a number that is rarely published.

A retailer in the normal scheme charges VAT, deducts the VAT they bear and remits the difference, so the tax costs them nothing: it passes through. One in the surcharge scheme pays 26.2 points on what they buy without deducting a single one,³ charges 21 on what they sell and keeps all of it.

With a cost C and a sale V, the net VAT cash of the retailer in the scheme is 0.21·V − 0.262·C, while in the normal scheme it is exactly zero. The two meet when the markup on cost equals surcharge divided by VAT:

Above that markup the surcharge costs less than the normal scheme; below it, more. And add what the arithmetic does not show: not filing form 303 and not keeping VAT ledgers has a value in hours and in accountancy fees.⁸

That two of those figures come out round (exactly 14% and exactly 12.5%) cannot be an accident: they are two rates fixed in two separate numbers of article 161 divided by two rates fixed in two separate paragraphs of article 91. The legislator calibrated the surcharge sector by sector, assuming in each band the margin that trade usually makes. And tobacco's 8.33% is the order of a licensed tobacconist's statutory commission, which is the most eloquent confirmation of all.

A worked example with real numbers

A stationer receives an invoice for €1,262.00 from their wholesaler.

Those €262 of tax are not deductible³ and cannot be passed to the customer.³

If the stationer resells that stock for €1,400 before VAT, they charge €294.00 of VAT and keep all of it, so their net VAT cash is €294.00 − €262.00 = €32.00 in their favour. Their 40% markup is above the 24.76% at which the two schemes tie, and the surcharge pays. With the same cost and a €1,245 sale their markup would be 24.5% and they would lose €0.55.

The three times you do have to file

«Nothing is ever filed under the scheme» is a comfortable sentence and it is false. Article 61.3 of the Regulation lists three cases:⁸

1. Intra-EU acquisitions and reverse charge. By far the most frequent. Buying stock in another EU country makes the retailer the taxable person for the VAT and the surcharge,⁵ paid on form 309 in the first twenty calendar days of April, July and October and the first thirty of January.⁹
2. Refunds of VAT to travellers. Whoever reimburses the tax to a non-EU traveller recovers it with form 308.¹⁰
3. Selling a property subject to and not exempt from VAT. Article 154.Dos expressly carves properties out of the scheme: on that operation the retailer charges, settles and pays like anyone.³

There is also a duty that is not a return but is very much the retailer's own: article 163 obliges them to prove to their suppliers, and to Customs, whether or not they are subject to the scheme.⁸ Say nothing and they will not charge it, and the breach will be yours.

Entering and leaving costs an inventory

On the day you enter the scheme and the day you leave it, the stock has to be counted.

Article 155 requires payment, on entry, of the VAT and the surcharge on the acquisition value of the inventoried stock, and allows that same amount to be deducted on exit.⁴ The bases are not identical: on the way in it is the acquisition value excluding VAT, on the way out excluding VAT and surcharge, and if the exit comes from the non-taxable transfer of the business to a trader who is not in the scheme, the buyer deducts on the market value of the stock. Three rules for what looks like the same sum.

Article 60 of the Regulation sets the deadline almost nobody quotes: the signed inventory is filed with the tax agency within fifteen days, and the payment or the deduction goes in the return for the period in which the change happened.⁸

None of this can be avoided by opting out: unlike the simplified scheme or the farming, livestock and fishing one, this admits no waiver. If the conditions are met, it applies.
