VAT on selling 3D printed parts: what you actually take home

You sell a part for 20 €, it cost you 5.11 € to produce, and you assume you made almost 15 €. The real sum leaves 8.95 €. The difference, 5.94 € per part, is split between the platform and the tax office, and almost nobody subtracts it before setting the price.

This article explains where that money goes, how VAT works when you sell 3D printed parts, and what changes the day you pass 10,000 € of sales to other European Union countries.

Note: this is general information to understand the numbers, not tax advice. Every situation has its own wrinkles — whether you are registered, whether you sell to consumers or businesses, whether the buyer is inside or outside the EU — and that needs an adviser looking at your case.

The full chain, from 20 € to 8.95 €

Take the same part we use across the site: 60 grams of PLA, five and a half hours of printing, fifteen minutes of work. It costs 5.11 € to produce. You list it at 20 € plus 4 € shipping on a marketplace like Etsy, registered as self-employed in Spain.

Of the 20 € in the shop window you keep 8.95 €, 45%. Anyone who only subtracts the production cost believes they made 14.89 €, 74%. The error is 5.94 € per part, and it grows with every sale.

We broke the fees down in the marketplace fees guide. Here we go after the other slice, the one the tax office takes.

The VAT you charge is not yours

This is the hardest idea to internalise at the start: when you sell at 20 €, those 20 € are not income. They are 16.53 € of yours and 3.47 € you are collecting for the tax office, because a consumer price includes VAT.

The standard rate in Spain is 21%. A 3D printed part does not fall under the reduced rates, so the standard one applies except in very specific cases which, again, an adviser should check.

Getting the net amount out of a VAT-inclusive price is a division, not a subtraction:

The classic mistake is subtracting 21% from the price: from 20 € that would give 15.80 €, and the correct figure is 16.53 €. Seventy-three cents on one part, but multiply it by two hundred sales.

The other side is that the VAT you pay buying filament, spare parts or a printer is deductible too, if you are registered and the purchase relates to the business. That input VAT is offset against the VAT you charge, so you do not lose it.

The other side: the VAT you get back

So far we have only looked at what you pay. But VAT runs both ways: what you are charged on your purchases is offset against what you charge on your sales, and you only hand over the difference.

A realistic quarter for somebody selling modestly: sixty parts at 20 €, plus the usual material purchases.

Keeping the invoices for everything you buy for the business saves you 41.65 € in this quarter. Not a fortune, but it is money lost purely by not asking for an invoice at the filament shop.

And one detail that gets forgotten: the printer itself also carries deductible VAT if you buy it once registered and it is used for the business. On a 400 € machine that is about 69 € back.

The 10,000 € threshold that changes everything

As long as you sell little outside Spain, life is simple: you apply Spanish VAT to everyone and declare it here like any other sale.

The rule changes when your sales to private consumers in other EU countries pass 10,000 € a year. That threshold is common to the whole Union and is counted by adding every country together, not country by country. From then on you must charge the VAT of the buyer's country, not the Spanish one.

In other words: the same part carries 19% if somebody in Germany buys it, 20% in France and 22% in Italy. And that VAT has to be paid in each country… unless you use the One Stop Shop, which exists precisely to avoid that.

The One Stop Shop: two forms and done

The scheme is called OSS (One Stop Shop) and it exists so that you do not have to register for tax in every country where you have a customer. You declare everything in Spain and the tax office distributes it.

Two procedures:

Form 035 — registering for the scheme. Filed once, on the Spanish tax agency's electronic office, and it takes effect almost immediately.

Form 369 — the return. It is quarterly for the Union scheme, and you have the whole calendar month following the end of the quarter to file it. In it you break down how much you sold to each country and at what rate, and pay the total in one go.

Watch out for one detail that catches people: form 369 does not replace your usual VAT return. Domestic sales keep going through their normal channel; the 369 only covers intra-EU distance sales.

How much the buyer's country changes your profit

If you keep the same consumer price across Europe, what you keep changes with each country's rate, because VAT sits inside the price. With the example part at 20 €:

The gap between best and worst case is 0.41 € per part, about 41 € every hundred sales. Not dramatic, but worth knowing: selling to Italy pays you less than selling to Germany at the same shop-window price.

If you want the same amount everywhere, the price has to move by country. To keep the 16.53 € net that Spain leaves, the price would have to be 19.67 € in Germany, 19.83 € in France and 20.17 € in Italy. Most small sellers do not bother and put the same number everywhere, absorbing that small difference.

The price that really leaves you 10 € clean

Here is the practical use of all the above. If you want to make 10 € clean per part, after fees, after VAT and after production cost, the price is not 15 €, nor 17 €.

It is 21.42 €.

The sum chains the three layers: the price minus marketplace fees, the result divided by 1.21 to strip out VAT, and from that the production cost subtracted. At 21.42 € with 4 € shipping, what stays in your pocket is exactly 10.00 €.

Compare that with what you would get ignoring those two layers: somebody looking only at cost and markup would price the part around 15 € and believe they were making 10. In reality they would be making barely 5. To try it with your own figures, start from your part's real cost and adjust the markup in the selling-price calculator until, after taking off 12.5% in fees and 21% in VAT, it still comes out where you want it.

Selling without being registered

The question that always comes up: can I sell four loose parts without registering for anything?

The honest answer is that it depends on whether there is regular activity, and that concept has no exact number in the law. Selling one print to a friend is not the same as running an open shop with a catalogue and weekly shipments. The second is economic activity, regardless of turnover.

What is certain: as soon as you open a shop on a marketplace and sell continuously, you are in the territory where registration is required, and marketplaces report their sellers' sales to European tax administrations.

I am not going to tell you where your line is, because I do not know and because it is not a decision an article should make. What I will say is that the numbers in this guide only add up if you are registered: without being able to deduct VAT on your purchases or invoice legally, the sum is different.

When to stop reading articles and call an adviser

There are situations where saving on an accountant does not cover the risk of getting it wrong. I would call as soon as any of these applies:

You are approaching 10,000 € of EU sales. Crossing that threshold without having filed form 035 means charging a VAT rate that does not apply.

You sell to businesses, not just consumers. B2C and B2B sales within the EU follow different rules, and that brings in the intra-community operators register.

You sell outside the EU. Exports, customs and another set of rules entirely.

You bought the printer before registering. Deducting VAT on goods acquired before registration has specific conditions.

For everything else — selling parts to Spanish consumers while registered — the numbers in this article give you enough of a picture to set prices that do not leave you at a loss.

What to take away

Three ideas, in order of importance:

The shop-window price is not your income. It has VAT inside it and fees are about to land on top. Of 20 €, 8.95 € are real with the part in this example.

To get the net amount, divide by 1.21. Do not subtract 21%, which gives a different and worse number for you.

The 10,000 € of EU sales is the border. Below it, Spanish VAT for everyone. Above it, the buyer's country VAT and the One Stop Shop with forms 035 and 369.

And if you are building your price list from scratch, the sensible order is: first the real production cost, then the markup you want, then the marketplace fees, and VAT last. In that order, not the other way round.
