Spain Inversión del Sujeto Pasivo: Reverse Charge IVA Guide

If you invoice from Spain — as an autónomo, a freelancer, or a small company — one Spanish phrase can completely change your invoice: inversión del sujeto pasivo. It means the reverse charge applies: instead of you adding 21% IVA on top of your price, your business customer accounts for the VAT themselves. Get it wrong in either direction — charging IVA when you should not, or skipping it when you must charge it — and you can face unpaid tax, a customer who cannot deduct anything, or corrective invoices and amended returns.

Spain's standard IVA rate is 21%, with reduced rates of 10% and 4% for specific goods and services. But in a growing number of cross-border and domestic situations, the normal rule flips: the supplier issues the invoice without IVA, and the buyer self-charges it. This guide explains exactly when that happens, what your invoice must say, and how to report it to the Spanish tax office (AEAT).

What "inversión del sujeto pasivo" actually means

Normally, the seller is the sujeto pasivo (taxable person): they charge IVA, collect it, and pay it to the tax office. The "inversión" flips this — the buyer becomes the taxable person for that transaction.

The mechanism rests on two legal pillars: Art. 84.uno of the Spanish VAT Act (Ley 37/1992, LIVA) — 84.uno.1º where the supplier is not established in Spain, 84.uno.2º for specific domestic supplies such as construction work and scrap — and Art. 196 of the EU VAT Directive (2006/112/EC), the basis for intra-EU business-to-business services, where the customer accounts for VAT in their own country.

New to the concept? Read our plain-English guide to reverse charge VAT in the EU first. One crucial point: when the conditions are met, reverse charge is not optional — you must not charge IVA, and charging it anyway leaves your customer with tax they may not be able to deduct.

When a Spanish supplier must not charge 21% IVA

There are four main situations where your invoice goes out with 0% IVA:

1. Intra-EU business-to-business services

You provide services to a business customer in another EU country — for example, a freelance designer in Barcelona invoices a German GmbH. Under the general place-of-supply rule (Art. 69 LIVA), the service is deemed to take place in the customer's country. You invoice the net amount with no IVA; the customer self-charges VAT in their country under Art. 196 of the EU VAT Directive. The customer must be a genuine, VAT-registered business — so verify their EU VAT number in VIES before issuing the invoice.

2. Intra-EU supplies of goods (entregas intracomunitarias)

Selling physical goods to a VIES-registered business in another EU member state? These deliveries are exempt under Art. 25 LIVA. Again, no IVA on the invoice — the customer accounts for VAT on arrival in their own country.

3. Specific domestic cases (Art. 84.uno.2º LIVA)

Even inside Spain, reverse charge applies to certain business-to-business supplies:

• Construction work: execution of works (with or without materials) and staff assignments under contracts directly agreed between the developer/promoter and the contractor, for land development or construction/rehabilitation of buildings.
• Scrap and waste: ferrous and non-ferrous metal residues, slag, ashes, and similar recyclable industrial waste.
• Emission allowances: trading of greenhouse-gas emission rights.
• Precious metals: silver, platinum, and palladium.
• Electronic devices: mobile phones, tablets, laptops, and game consoles — to habitual resellers, or to other business buyers when one invoice exceeds €10,000 excluding IVA.
• Real estate in insolvency: certain property transfers in bankruptcy proceedings.

4. What never qualifies

Selling to private consumers (B2C) never triggers reverse charge — always charge normal IVA. If unsure a case qualifies, the safe default is to charge IVA.

The exact invoice wording: "Inversión del sujeto pasivo"

Spanish invoicing rules (Art. 6.1.m of Royal Decree 1619/2012) make the wording mandatory: when the recipient is the taxable person, the invoice must carry the mention "Inversión del sujeto pasivo". A practical line that works for Spanish and foreign clients alike:

"Inversión del sujeto pasivo — Reverse charge: VAT to be accounted for by the recipient (Art. 84.uno LIVA)."

Also include your NIF, the client's name and valid EU VAT number with country prefix, the date, invoice number, a description, the net taxable base — and an IVA line showing 0%. Keep proof: a record of the VIES check, and for goods, evidence of transport to the other member state.

ROI/VIES registration: the step people forget

To issue intra-EU invoices without IVA, you must be registered in the ROI (Registro de Operadores Intracomunitarios) with the AEAT. ROI registration puts your NIF on the EU-wide VIES system with an ES prefix — without it, your "no IVA" invoices are not valid cross-border. Apply online via the AEAT; approval typically takes days to weeks, so do not wait until the invoice is due. Your customer must also hold a valid VIES-registered VAT number — always check it before issuing.

How to declare it: Modelo 303, Modelo 349, and Modelo 390

Reverse charge does not mean "no paperwork". As the supplier, you still declare these operations:

• Modelo 303 (quarterly IVA return): report the net amounts in the dedicated boxes (for example, box 61 covers exempt intra-EU supplies of goods). The return shows the turnover with no IVA charged.
• Modelo 349 (recapitulative statement): declare each intra-EU customer, their VAT number, and the totals per customer with the correct operation key (key "E" for deliveries of goods, the services key for intra-EU services). This lets EU tax offices cross-check your customer's self-charged VAT.
• Modelo 390 (annual summary): filed together with the fourth-quarter Modelo 303, it consolidates everything — intra-EU operations appear in the dedicated annual boxes (such as box 523).

When you are the one receiving a reverse-charge invoice as a Spanish business, you self-charge ("autorrepercutirse"): record the IVA as both output and input VAT in your Modelo 303. The two entries normally cancel out (net zero cash effect) as long as you can fully deduct. Also report the acquisition in Modelo 349 and Modelo 390.

Worked example: €1,000 net invoice to an EU VAT-registered client

Sofía is an autónoma web developer in Valencia. A French SARL hires her for a €1,000 project. Sofía is ROI-registered, and the client's FR-prefixed VAT number validates in VIES.

• Sofía issues the invoice for €1,000 net, 0% IVA, with the "Inversión del sujeto pasivo" mention and both VAT numbers shown.
• The client pays exactly €1,000 — no IVA crosses the border.
• The French company self-charges 20% French TVA (€200) in its own return and deducts it the same period — cash-neutral for them.
• Sofía declares the €1,000 in her Modelo 303, lists the French client in Modelo 349, and includes it in Modelo 390.

Frequently asked questions

Can I use reverse charge for a Spanish private customer?

No. Reverse charge only applies between businesses. Sales to private consumers always carry normal Spanish IVA.

Do I need ROI registration for domestic reverse charge, like construction work?

No. ROI is only required for intra-EU (cross-border) operations. For domestic cases — construction, scrap, emissions allowances — both parties simply need to be businesses, and the invoice must carry the "Inversión del sujeto pasivo" mention.

What if I charged 21% IVA by mistake on a reverse-charge invoice?

Fix it promptly: issue a corrective invoice (factura rectificativa) removing the IVA, and amend the affected Modelo 303 (and 349/390 if needed). Your customer cannot safely deduct IVA that should never have been charged.

Does reverse charge apply to the Canary Islands, Ceuta, or Melilla?

These territories are outside the IVA area (the Canaries use IGIC instead). Operations with them are generally treated like non-EU transactions for IVA purposes — do not apply standard intra-EU reverse-charge logic without checking the specific case.

My client has no VAT number. Can I still skip the IVA?

No. A valid, VIES-verified EU VAT number for your customer is a hard requirement for intra-EU reverse charge. Without it, charge Spanish IVA — treat the client as a non-business customer.
