Spain IVA for E-Commerce 2026: Rates, OSS Registration, SII & Compliance Guide

The 2026 Spanish IVA Landscape at a Glance

Few European IVA systems are as layered as Spain's. The cards below summarise the four active bands plus the AEAT and SII infrastructure - keep them nearby as you read each deep-dive section.

1. Spanish IVA Rates 2026 - 21%, 10%, 4%, 0%

The Four-Band System

Spanish IVA is structured under Ley 37/1992 del Impuesto sobre el Valor Anadido, implemented by Real Decreto 1624/1992, and updated by successive Royal Decree-Laws responding to inflation, energy crises and EU directive transpositions. As of 2026 there are four active bands:

The 0% Rate - A Temporary but Recurring Layer

From January 2023 the Spanish government introduced a temporary 0% IVA on a defined basket of basic foodstuffs as part of anti-inflation measures (Real Decreto-Ley 20/2022 and successors). The 0% basket has been extended in 2024, 2026 and again partially into 2026, covering: bread and bread flour, milk, cheese, eggs, fresh fruit, vegetables and tubers, cereals, legumes and dried fruit. Olive oil was permanently moved to the 4% super-reduced band from 1 January 2024. Sellers of consumables must check the live Real Decreto-Ley applicable to each SKU, since the basket is reviewed semi-annually.

Canary Islands, Ceuta and Melilla - Outside IVA

Spain's IVA does not apply in the Canary Islands (which use IGIC - Impuesto General Indirecto Canario, currently 7% general), Ceuta and Melilla (which use IPSI - Impuesto sobre la Produccion, los Servicios y la Importacion). Goods shipped from mainland Spain to these territories are treated as exports (IVA-zero with export documentation), and imports from them into the peninsula are treated as intra-community-equivalent imports. Most e-commerce operators configure two parallel tax engines: peninsula+Balearic IVA, and Canary/Ceuta/Melilla IGIC/IPSI.

2. AEAT Registration for Foreign E-Commerce Sellers

Who Needs a Spanish NIF-IVA?

The NIF-IVA (Numero de Identificacion Fiscal a efectos del IVA) is Spain's VAT identification number. You need one if any of these triggers apply:

• You store goods physically in Spain - including Amazon FBA centres (MAD4 San Fernando de Henares, MAD8 Illescas, BCN1 El Prat, SVQ1 Sevilla), other 3PL warehouses or own facilities
• You import goods into Spain in your own name outside the IOSS regime
• You make domestic supplies - B2C or B2B - within Spanish territory beyond the OSS scope
• You are a non-EU seller using OSS Non-Union scheme with Spain as your Member State of Identification
• You exceed the OSS distance-sales threshold of 10,000 EUR EU-wide and choose local registration instead of OSS

The Registration Process

Foreign sellers register via Modelo 036 (Declaracion censal de alta, modificacion y baja en el censo de empresarios, profesionales y retenedores) submitted to AEAT. EU-established sellers without a fixed establishment in Spain typically use the simplified flow; non-EU sellers must additionally appoint a Spanish tax representative (representante fiscal) jointly and severally liable for the IVA obligations - this is mandatory under Article 164.Cuatro of Ley 37/1992.

Practical timing in 2026: a clean Modelo 036 with a complete corporate documentation pack takes 2-6 weeks to obtain the NIF-IVA. AEAT requires apostilled corporate documents, beneficial-ownership declarations and proof of the tax representative's mandate. Once issued, the NIF-IVA also unlocks VIES validation for B2B intra-community trade.

NIE vs CIF vs NIF-IVA

A frequent source of confusion. NIE (Numero de Identidad de Extranjero) identifies foreign natural persons in Spain. CIF (Codigo de Identificacion Fiscal) was the legacy tax ID for Spanish companies; replaced administratively by NIF (Numero de Identificacion Fiscal) since 2008. The NIF-IVA is the NIF with the ES prefix used in intra-community trade (e.g. ESB12345678 for an SL company). For B2B reverse charge to work, only the NIF-IVA - validated in VIES - matters.

Ongoing Filing Obligations

• Modelo 303 - quarterly (or monthly for REDEME/SII taxpayers) IVA self-assessment
• Modelo 390 - annual IVA summary (waived if SII is active)
• Modelo 349 - monthly/quarterly recap statement of intra-community supplies and acquisitions
• Modelo 369 - quarterly OSS return (for the OSS Union/Non-Union/Import schemes)

3. OSS - One Stop Shop for B2C Cross-Border

What OSS Solves

Before 1 July 2021, distance-sale thresholds varied by country (Spain's was 35,000 EUR) and crossing them required a local VAT registration in each member state. The EU VAT e-commerce package replaced that with the unified OSS - One Stop Shop. Under OSS, an EU-established seller registers in a single Member State of Identification (their country of establishment) and files one consolidated quarterly return covering all B2C cross-border sales across the EU.

The Three OSS Schemes

• Union Scheme - for EU-established sellers doing cross-border B2C distance sales of goods and services. The most common scheme in practice.
• Non-Union Scheme - for non-EU established sellers supplying services to EU consumers (e.g. SaaS, digital products, professional services). Goods are not covered by this scheme.
• Import Scheme (IOSS) - see section 4 below; for low-value imports up to 150 EUR.

The 10,000 EUR Threshold

Under Article 73 of Ley 37/1992 transposing EU Directive 2017/2455, micro-businesses with total cross-border B2C EU sales below 10,000 EUR per calendar year charge their domestic VAT and report nothing to OSS. Once that threshold is crossed at any point in the year, the seller must either register for OSS or for VAT in every member state where they make distance sales. There is no reset for low single-month spikes; the calculation is calendar-year cumulative.

OSS Registration in Spain - Modelo 035 and 369

Sellers established in Spain register for OSS via Modelo 035 on the AEAT sede electronica. Approval is typically same-day. From the first day of the following calendar quarter, every cross-border B2C sale to other EU countries must be filed via the quarterly Modelo 369 (due by the end of the month following the quarter). The return itemises sales per destination country at that country's VAT rate, and AEAT redistributes the collected VAT to the destination treasuries.

OSS vs Local Registration - When to Pick Each

OSS is dramatically simpler than 27 separate registrations and is the default choice for most cross-border sellers. The exceptions are:

• You hold stock in multiple EU countries (e.g. Amazon Pan-EU FBA across Germany, France, Italy, Spain, Poland) - you still need local VAT registrations in each storage country, because OSS only covers B2C sales from the seller's country to another EU country, not movements between warehouses or local sales from a foreign warehouse.
• You have significant local B2B volumes that benefit from input-VAT recovery on local expenses - local registration may make recovery cleaner.
• You are below the 10,000 EUR threshold - file nothing under OSS, just charge domestic VAT.

4. IOSS - The 150 EUR Import Threshold

The End of the 22 EUR Exemption

Until 1 July 2021, EU imports below 22 EUR were exempt from import VAT. That exemption was abolished by Directive 2017/2455. Every commercial consignment imported into the EU is now subject to VAT, but the IOSS - Import One Stop Shop creates a simplified collection channel for low-value consignments up to 150 EUR intrinsic value.

How IOSS Works in Practice

The non-EU seller (or the deemed-supplier marketplace) registers for IOSS in one EU member state and receives a unique IOSS identification number. At checkout, the seller charges the destination-country VAT (21% for Spanish customers buying general-rate goods). The IOSS number travels with the parcel via electronic customs data; the parcel clears EU customs without further VAT collection. Monthly, the seller files a single Modelo 369 equivalent (the IOSS return) declaring sales per destination country.

Marketplace Deemed-Supplier Rule

Under Article 14 bis of Ley 37/1992, marketplaces that "facilitate" certain B2C sales are deemed to be the supplier for VAT purposes. The two cases are:

• Distance sales of imported goods up to 150 EUR - regardless of the underlying seller's establishment
• Supplies within the EU by non-EU established sellers - intra-EU B2C sales by Chinese, Turkish, US sellers selling stock already located in EU FBA centres

This is why Amazon, AliExpress, Temu, Shein, eBay and Etsy collect Spanish IVA on most low-value cross-border B2C transactions: they have no choice. The underlying seller invoices the marketplace VAT-zero (B2B intra-community supply), and the marketplace invoices the Spanish consumer with IVA.

What Falls Outside IOSS

• Consignments above 150 EUR - subject to standard import VAT collected on delivery, plus customs duty
• Excise goods - alcohol, tobacco, perfumes - always outside IOSS regardless of value
• B2B imports - handled via standard import VAT and reverse charge mechanisms, not IOSS

5. SII - Real-Time IVA Reporting Mandatory Since 2017

What SII Is

SII - Suministro Inmediato de Informacion del IVA is Spain's real-time IVA reporting infrastructure. Established by Real Decreto 596/2016 and operational from 1 July 2017, SII replaces the traditional paper-based libros registro (VAT registers) and certain annual forms with electronic transmission of invoice metadata to AEAT through a SOAP/XML web service.

Who Must Use SII

• Large taxpayers - businesses with annual turnover above 6,010,121.04 EUR (Article 121 Ley 37/1992)
• REDEME taxpayers - those in the monthly VAT refund register
• VAT groups - entities applying the special VAT group regime (Article 163 quinquies)
• Voluntary opt-in - any other taxpayer can opt in via Modelo 036; once opted in, you commit for the rest of the calendar year

The Four-Day Reporting Window

Invoice records must reach AEAT within 4 calendar days from issuance (weekends and public holidays excluded). For taxpayers that opt in voluntarily and have no ERP automation, an 8-day window applies for a transition period. Missing the window triggers SII-specific penalties: 0.5% per record, with a quarterly minimum of 300 EUR and maximum of 6,000 EUR.

What SII Replaces

• Libros registro de IVA - the paper-equivalent issued-invoice register, received-invoice register, investment-goods register and intra-community-operations register are all replaced by their SII feeds
• Modelo 340 - operations register declaration - obsolete for SII taxpayers
• Modelo 347 - third-party operations declaration above 3,005.06 EUR - obsolete for SII taxpayers
• Modelo 390 - annual IVA summary - waived for SII taxpayers

The SII XML Schema

SII uses a tightly specified SOAP/XML interface published by AEAT at www2.agenciatributaria.gob.es. Each invoice record carries: issuance date, invoice number, counterparty NIF or NIF-IVA, taxable base by rate, IVA quota by rate, special-regime keys (REAGyP, REBU, criterion of cash, etc.), and corrective-invoice references. Implementation requires a valid FNMT or equivalent digital certificate for AEAT authentication.

6. Verifactu 2026 - The New Anti-Fraud Certification

The Legal Basis

Verifactu is the colloquial name for the invoicing-software certification system created by Real Decreto 1007/2023, of 5 December, implementing Article 29.2.j) of the General Tax Law as added by the Ley 11/2021 anti-fraud law. The technical specification was further detailed by Orden HAC/1177/2024 published in October 2024. Together they impose strict requirements on every invoicing software used by Spanish taxpayers - eliminating "dual-use" software that allows sales suppression.

What Verifactu Requires

• Invoice integrity - every issued invoice must produce a chained hash referencing the previous invoice, making post-hoc deletion or modification detectable
• Tamper-proof record - the high-integrity invoicing record (RAFAH) must be unmodifiable and complete
• QR code on every invoice - encoding key invoice data and (optionally) a verification URL to AEAT's portal
• Verifactu transmission - either real-time transmission of each invoice to AEAT (the "Verifactu mode") or maintenance of a verifiable internal record (the "non-Verifactu mode" - higher inspection burden)
• Software vendor responsible declaration - the software publisher must issue a responsible declaration to AEAT attesting to compliance

The 2026 Rollout Calendar

• 1 January 2026 - mandatory for taxpayers subject to Corporate Income Tax (Impuesto sobre Sociedades) - i.e. all Spanish companies (SL, SA, etc.)
• 1 July 2026 - mandatory for the remaining taxpayers, including autonomos (self-employed) and natural persons subject to IRPF
• Software vendor compliance - publishers had to certify their products by mid-2026; using non-certified software after the applicable date triggers seller penalties

Verifactu vs SII - Two Different Things

This is a common confusion. SII reports invoice metadata after issuance for IVA compliance; Verifactu certifies the software that issued the invoice for anti-fraud purposes. The two systems coexist: SII-mandated taxpayers (large companies, REDEME) submit SII feeds and their invoicing software must be Verifactu-compliant from January 2026. Smaller taxpayers below SII thresholds still need Verifactu-compliant software but file VAT through Modelo 303 quarterly.

Penalties for Non-Compliant Software

• Sellers using non-compliant software - up to 50,000 EUR per year of use under Article 201 bis of Ley General Tributaria
• Software vendors producing non-compliant software - up to 150,000 EUR per type of invoicing system and per year
• "Dual-use" software - software allowing invoice suppression: dedicated heavier penalties

7. Amazon.es FBA - Automated IVA Handling

Spain's FBA Centre Network

Amazon operates five major fulfillment centres on Spanish soil in 2026: MAD4 San Fernando de Henares (the original 2017 launch), MAD8 Illescas (Toledo, mega-centre opened 2022), BCN1 El Prat (Barcelona), SVQ1 Sevilla La Rinconada and several mid-size sortation centres. Storing stock in any of these triggers automatic Spanish IVA obligations for the seller, regardless of marketplace.

VAT Calculation Services (VCS)

Amazon VAT Calculation Services (VCS) automates the rate-application step at checkout. Sellers upload a tax-classification mapping (Amazon Product Tax Code -> Spanish IVA rate) and Amazon applies the correct rate to each B2C order. VCS also generates VCS invoices automatically on behalf of the seller, satisfying the Spanish factura simplificada requirement for orders below 3,000 EUR.

Deemed-Supplier vs Seller-Responsible

The split is determined by Article 14 bis of Ley 37/1992:

• Amazon as deemed supplier (Amazon charges, collects and remits Spanish IVA): non-EU sellers shipping into Spain via IOSS (up to 150 EUR), or non-EU sellers selling stock already in EU FBA centres to Spanish B2C customers
• Seller as taxable person (seller charges, collects, files): EU-established sellers using Spanish FBA - regardless of whether the buyer is in Spain or another EU country

Pan-EU FBA and Storage-Country IVA

Sellers enrolled in Pan-EU FBA have stock distributed automatically across Germany, France, Italy, Spain, Poland, Czechia and the Netherlands. Each storage country triggers an obligation to register for local VAT - OSS does not cover stock movements or local sales from foreign warehouses. The typical Pan-EU FBA seller therefore holds 5-8 EU VAT registrations in parallel. Zunapro consolidates filings across all storage countries from a single ledger.

Amazon VAT Reports - Reconciliation Pain

Amazon publishes monthly VAT Transactions Reports and VCS Invoice Reports via Seller Central. Reconciling these against your SII feeds, OSS Modelo 369 entries and Modelo 303 quarterly returns is non-trivial: timezone differences, refund timing, returns crossing month-end, and FBA inbound movements all create line-item drift. Zunapro automates this reconciliation; expect 1-3% of lines to require manual review on a typical month.

8. Reverse Charge B2B - Inversion del Sujeto Pasivo

The Mechanism

Under Article 84.Uno.2 of Ley 37/1992, in defined B2B scenarios the obligation to self-assess IVA shifts from the supplier to the buyer - the inversion del sujeto pasivo (reverse charge). The supplier issues an invoice without IVA (with the legend "Inversion del sujeto pasivo - Art. 84.Uno.2 LIVA"), and the buyer reports both output and input IVA on the same Modelo 303, cancelling out for fully recoverable taxpayers.

Where Reverse Charge Applies

• Intra-community supplies of goods - EU seller -> Spanish buyer with valid NIF-IVA (Article 25 Ley 37/1992)
• Intra-community supplies of services - general place-of-supply rule for B2B services (Article 69 Ley 37/1992)
• Construction and refurbishment services between businesses
• Mobile phones, tablets, laptops and computer chips in B2B sales above 10,000 EUR per invoice (Article 84.Uno.2.g) - anti-fraud measure since 2014
• Scrap metal, waste, recyclables
• Emission allowances (CO2 quotas)

The VIES Validation Requirement

To invoice an EU customer without IVA under reverse charge, the supplier must validate the buyer's NIF-IVA against VIES (VAT Information Exchange System) at the time of the supply. AEAT can deny the reverse-charge treatment retroactively if VIES validation was missing or invalid - the supplier is then liable for the unpaid IVA. Store the VIES validation timestamp alongside each B2B invoice.

Reporting - Modelo 349 Recap Statement

Every intra-community supply or acquisition must be reported on Modelo 349 - the recapitulative statement of intra-community operations. The default filing period is monthly; quarterly is allowed when intra-community supplies stay below specific thresholds. Modelo 349 cross-checks every EU-wide intra-community movement against the counterpart's filing in the destination country - mismatches trigger AEAT enquiries.

9. Penalties and Sanctions for IVA Non-Compliance

The Penalty Architecture

Spanish tax penalties are governed by Ley General Tributaria (Ley 58/2003), Title IV. Penalties are tiered by culpability (negligence vs intent), and many can be reduced 25-30% for prompt payment and agreement to settle. The headline categories:

Late Filing Without AEAT Notice (Recargo Extemporaneo)

Under Article 27 LGT, voluntary late filing before AEAT notifies you carries no formal penalty - only a surcharge:

• 1% per month of delay (no late interest) for the first 12 months
• 15% plus late interest after 12 months
• 50% reduction on these surcharges if paid within the voluntary period

Filing After AEAT Notification (Sanciones Tributarias)

• Failure to file/pay IVA - 50% to 150% of the unpaid amount, depending on culpability, presence of concealment and recidivism (Articles 191-192 LGT)
• Aggravating factors - concealment of data, use of false invoices, fictitious counterparties - push penalties to the upper band
• Mitigating factors - agreement to settle (reduction 30%), prompt payment (additional 40%) - can drop the effective penalty significantly

Invoice-Related Penalties

• Failure to issue invoices - 1% to 2% of the value of unbilled transactions (Article 201 LGT), minimum 300 EUR
• Invoice content defects - 1% of inaccurate invoice value, minimum 150 EUR
• Invoice numbering breaks - 75 EUR per invoice issued out of sequence

SII Penalties

• Late SII submission - 0.5% of the omitted record value, quarterly minimum 300 EUR, maximum 6,000 EUR per calendar quarter
• Incomplete SII data - 1% of the invoice value with same minimum/maximum
• Total SII failure - escalates to general LGT penalties if the omission causes IVA underpayment

Verifactu Software Penalties (from 2026)

• Using non-certified invoicing software - up to 50,000 EUR per fiscal year of use (Article 201 bis LGT)
• Software vendor producing non-compliant systems - up to 150,000 EUR per system per year
• "Dual-use" software supporting sales suppression - dedicated heavier sanctions and potential criminal referral

Criminal Liability - Delito Fiscal

Under Article 305 of the Spanish Criminal Code (Codigo Penal), tax fraud exceeding 120,000 EUR per fiscal year per tax is a criminal offence, punishable by 1 to 5 years prison and a fine of 1-6x the defrauded amount. Aggravated cases (organised crime, false invoicing networks, defraudations above 600,000 EUR) carry 2 to 6 years prison. The voluntary disclosure of fraud before AEAT acts can extinguish criminal liability under specific conditions.

10. Practical 2026 Compliance Roadmap

Step 1 - Map Your Footprint

• Where is your company established? EU-resident, non-EU, Spanish
• Where do you hold stock? Spain only, multi-EU, no EU stock
• What is your B2C cross-border EU turnover? Above or below 10,000 EUR/year
• What is your domestic Spanish turnover? Above or below the 6,010,121.04 EUR SII trigger
• Are you subject to Corporate Income Tax (Sociedades)? Determines Verifactu deadline (Jan 2026 vs July 2026)

Step 2 - Choose Your Registration Stack

• EU seller, no Spanish stock, cross-border B2C above 10K -> OSS in your home country
• EU seller, Spanish FBA stock -> Spanish NIF-IVA + OSS in home country for cross-border
• Non-EU seller, Spanish FBA -> Spanish NIF-IVA + tax representative + IOSS for low-value imports
• Spanish company -> Spanish NIF-IVA + SII (if above threshold) + OSS for cross-border + Verifactu from Jan 2026

Step 3 - Certify Your Invoicing Software (Critical for 2026)

Verifactu certification is the single most pressing 2026 deadline. Action items:

1. Inventory every invoicing system used by your business (ERP, e-commerce platform, point-of-sale, manual templates)
2. Demand the vendor responsible declaration from each provider; if the vendor cannot produce one, replace the software
3. If you operate a Spanish SL/SA - the Jan 2026 deadline is hard; budget for migration by Q4 2026
4. If you are an autonomo - the July 2026 deadline gives an extra six months, but use them

Step 4 - Activate SII (If Required)

1. Verify SII obligation: turnover > 6M EUR, REDEME, VAT group, or voluntary opt-in
2. Generate FNMT or equivalent digital certificate for AEAT authentication
3. Configure your ERP/Zunapro for the SII SOAP endpoint (production URL after sandbox validation)
4. Test the four core feeds: issued invoices, received invoices, investment goods, intra-community operations
5. Submit your first live batch and validate AEAT response codes

Step 5 - Validate B2B Counterparties in VIES

For every B2B EU customer you intend to invoice under reverse charge, validate the NIF-IVA in VIES at order time. Store the validation timestamp and the AEAT-returned counterparty name and address. Without this, AEAT can claim retroactive IVA on the supply.

Step 6 - Reconcile Marketplace Reports Monthly

• Amazon VAT Transactions Report vs SII feed vs Modelo 303
• eBay VAT Report vs SII feed
• AliExpress / Temu IOSS reports vs Modelo 369
• Marketplace settlement statements (commissions, returns) vs your purchase ledger

Step 7 - Archive Digital Records

Spanish IVA records must be kept for 4 years by default (general LGT prescription), extended to 6 years for SII feeds and certain Verifactu records. Records must be retrievable in their original digital form with proof of integrity. Cloud archive with chained-hash integrity is the modern best practice.

Step 8 - Plan for OSS Quarterly Returns

Modelo 369 (OSS) is due by the end of the month following each calendar quarter (April 30, July 31, October 31, January 31). Late filing penalties start at 100 EUR and escalate. Automate the data pipeline early - manual extraction from Shopify/WooCommerce/Amazon does not scale past low-thousand orders/quarter.
