E-Invoice Italy for Foreigners 2026: The Chartered Accountant's Complete Guide
- As a non-resident entity with no permanent establishment in Italy, you can issue e-invoices only through a fiscal representative or an authorised provider.
- The Sistema di Interscambio (SdI) managed by the Italian Revenue Agency has been mandatory since 1 January 2019: there are no "I'm a foreigner" exemptions.
- Without a codice destinatario or certified email (PEC), your invoice will never be delivered and the client may refuse payment or challenge the cost deduction.
When I sit across from a foreign client — whether a Berlin-based IT consultant billing a Milanese client, or a German GmbH selling machinery in Italy — the first thing I see in their eyes is the same confusion: "But I'm foreign, does the Italian e-invoice really apply to me?". Yes, it does. The fact that you're abroad doesn't exempt you: it just makes the path slightly more complex. Let me show you how it actually works.

What Is the Italian E-Invoice and Why It Exists
The Italian e-invoice (fattura elettronica) is a tax document in XML format (structured markup language) that must be mandatorily transmitted to the Sistema di Interscambio (SdI), the IT infrastructure managed by the Italian Revenue Agency (Agenzia delle Entrate).
It's not a PDF, not an email with an attachment. It's a structured file following precise technical specifications, which the SdI automatically routes to the final recipient (public administration or private party).
Legal reference: the definitive shift came with the Budget Law 2018 (L. 205/2017), which made e-invoicing mandatory for B2B and B2C transactions starting 1 January 2019. Since then, no exceptions of any kind.
Why does it exist? Three reasons I explain to my clients:
- VAT anti-evasion: the Revenue Agency sees in real time who bills what, and VAT is automatically paid
- Simplification for the client: no more paper registers, everything downloads from SdI or the taxpayer's "cassetto fiscale"
- European standardisation: the XML format follows UN/CEFACT CII (Cross-Industry Invoice), aligned with EU Directive 2014/55/EU on electronic invoicing in public procurement
Who Must Issue It: The Obligation Applies to Foreigners Too
Here is the question. The one I get asked all the time.
| Type of entity | E-invoice obligation in Italy | Notes |
|---|
| Italian SRL/SPA | ✅ Yes, always | Mandatory since 1/1/2019 |
| Sole proprietorship / Italian VAT number | ✅ Yes, always | Mandatory since 1/1/2019 (with the historical "minimi" regime exception, no longer open) |
| EU freelancer with Italian VAT number | ✅ Yes, always | Once you have an Italian VAT number, the obligation applies |
| EU company without permanent establishment | ⚠️ Yes, if billing an Italian VAT subject | Issued through a fiscal representative or via direct identification |
| Non-EU company | ⚠️ Yes, if billing an Italian VAT subject | Same rules, with added complexity around representation |
| Private consumer (B2C) | ❌ No | The obligation is B2B/B2C towards VAT subjects only |
Legal reference: Article 1, paragraphs 909-928, of L. 205/2017 introduced the obligation. The technical specifications are in the Director's Provision of the Italian Revenue Agency dated 30 April 2018, updated multiple times through 2024.
The "forfettario" case
A clarification that saves fines: even those in the regime forfettario (the 5%/15% flat-tax regime for small businesses) are required to issue e-invoices. I know, it seems paradoxical — I'm paying 5% or 15% as a substitute tax, why do I need to issue e-invoices? Because the obligation is formal, not substantive. You are not applying VAT (you are excluded), but you still need to document the transaction in XML format.
The Sistema di Interscambio (SdI) in 3 Minutes
SdI is not a software you install. It is a central hub of the Revenue Agency that:
- Receives the XML invoice from the sender
- Verifies formal correctness (tax code, VAT number, "natura" codes, etc.)
- Forwards to the recipient (who has a 7-character code or a PEC)
- Returns a delivery receipt (or a rejection if there are errors)
Everything happens in seconds. When you see the green light on your provider's platform, the invoice is technically issued. When the client confirms receipt, it is also delivered.
What happens when the client is small and has no code?
Since 1 July 2022, the so-called "default recipient code" changed. For small entities that have not communicated a custom code, the SdI makes available the code "0000000" and delivers the invoice to the recipient's cassetto fiscale (taxpayer's online portal). The client downloads it from there.
Practical tip: if you frequently bill the same clients, always ask for the 7-character codice destinatario that their accountant or invoicing software issues them. It's the fastest route.
Codice Destinatario and PEC: What They Are and How to Get Them
Codice destinatario
A 7-character alphanumeric code (e.g. ABC1234) that uniquely identifies an invoice reception channel. It is issued by:
- Your accountant or SdI provider when configuring the service
- The Revenue Agency itself through the "Fatture e Corrispettivi" portal
PEC (Certified Email)
An alternative to the codice destinatario. If you specify the recipient's PEC, the SdI delivers the invoice there. The PEC must be in the name of the recipient entity (VAT number or tax code).
| Method | When to choose it |
|---|
| 7-character codice destinatario | Recommended for ongoing relationships (consultants, suppliers) |
| PEC | When the client has no code and wants everything via certified email |
Code 0000000 | Only for B2C or for those who have not communicated a channel (delivery to cassetto fiscale) |
This is the point that panics most of my foreign clients. Let me clarify.
The fiscal representative (rappresentante fiscale) in Italy is a natural or legal person, resident in Italy, who:
- Is appointed by the non-resident entity (via public deed or authenticated private deed)
- Has their own Italian tax code
- Receives e-invoices on behalf of the represented entity (the foreign entity)
- Fulfils VAT obligations on behalf of the represented entity
- Is jointly and severally liable with the represented entity for tax compliance
When it is mandatory
You need a fiscal representative if:
- You are a non-resident entity (no permanent establishment in Italy)
- You issue invoices in Italy or receive services with mandatory e-invoicing
- You do not want (or cannot) directly identify yourself in Italy with a tax code
Alternative: direct identification
Instead of a representative, you can ask the Revenue Agency for direct VAT identification, which allows you to:
- Obtain an Italian VAT number
- Operate autonomously on the SdI
- Directly fulfil tax obligations
Legal reference: Article 17, paragraphs 2 and 3, of DPR 633/1972 governs the fiscal representative. Direct identification is regulated by Article 35-ter of the same DPR.
| Option | Annual cost (indicative) | Pro | Con |
|---|
| Fiscal representative | €500–€2,000/year | Flexible, someone does it for you | Cost, joint liability |
| Direct identification | €0 (only accountant for the application) | Full autonomy | You need a knowledgeable accountant |
| Permanent establishment | Variable | For high volumes | Significant legal/fiscal complexity |
Practical tip: for most foreign freelancers billing under €100k/year in Italy, direct identification + a good accountant is almost always the most efficient choice.
Three Concrete Scenarios to Make It Click
Scenario 1: IT Consultant in Berlin with Italian Clients
- Marco lives in Berlin, has a German VAT number (Kleinunternehmer or standard regime)
- Has 4 Italian clients requesting invoices with Italian VAT
- Solution: direct identification in Italy (Italian VAT number) + SdI
- Annual cost: accountant €800/year + SdI provider €100/year
Scenario 2: German GmbH Selling Machinery in Italy
- Müller GmbH is a German GmbH with DE VAT
- Sells to Italian B2B clients
- Solution: direct identification or fiscal representative. If billing > €10k/month in Italy, we recommend a permanent establishment
- Annual cost: €1,500–€3,000/year between accountant and provider
Scenario 3: UK Freelance Designer (Post-Brexit)
- Sarah is UK resident, wants to invoice a Milanese agency
- UK is no longer in the SdI, no simplified reverse charge
- Solution: direct identification + representative for the declarative side
- Watch out: Sarah must also handle UK obligations (Making Tax Digital) and double-taxation treaties

There are dozens of platforms. Main categories:
1. Italian Revenue Agency Software (Free)
- "Fatture e Corrispettivi" on the AdE portal
- Pro: free, made by the Agency

Costs: What You'll Actually Spend in 2026
Here is a realistic estimate of annual costs for a non-resident issuing e-invoices in Italy:
| Item | Annual cost | Notes |
|---|
| Accountant for direct identification | €500–€1,500 | One-off + maintenance |
| SdI provider (Fatture in Cloud, Aruba, etc.) | €50–€300 | Often included for 100-500 invoices/year |
| Digital storage (mandatory) | €50–€200 | Often included in the provider fee |
| PEC for the representative | €20–€50 | Only if you use PEC as a channel |
| Indicative total | €700–€2,000/year | Depending on volume |
Invoice Storage: 10 Years, Not 5
A mistake I see constantly: clients think storage for 5 years (the ordinary tax assessment limitation period) is enough. Wrong.
E-invoices must be stored for:
- 5 years for tax purposes (art. 57 DPR 633/1972) — assessment limitation period
- 10 years for civil purposes (art. 2220 Italian Civil Code) — contract action limitation period
So you must store them for 10 years. In digital format, following the rules of the Revenue Agency (CNIPA Deliberation 11/2004 and subsequent updates).
Your provider usually includes compliant digital storage (mandatory) in the fee. Check that this is explicit in the contract.
Common Mistakes I See Every Month
- Sending the invoice by email in PDF thinking it's enough. No, it must go through the SdI.
- Entering your own foreign tax code in the "codice destinatario" field. Blocking error. That field is for the recipient, not the sender.
- Forgetting the "codice natura" when VAT is not applied (e.g. forfettario transaction: code N2.2 is needed).
- Confusing reverse charge with e-invoice. They are two different things. Reverse charge is a tax operation; e-invoice is the format. You can have reverse charge with an XML invoice and you must fill in the fields correctly.
- Invoicing in foreign currency. Yes, you can, but you must indicate the exchange rate in a specific field and the EUR amount must be calculated correctly.
- Digitally signing the file. Not mandatory for invoices to private parties. It becomes necessary only for specific documents (e.g. certified copies).
Frequently Asked Questions (FAQ)
Can I issue an e-invoice without an Italian VAT number?
No. To issue an invoice to the SdI you need an Italian tax code or Italian VAT number. Non-residents must therefore request direct identification or appoint a fiscal representative.
Do I have to issue an e-invoice to private clients (B2C) too?
Yes, since 1 January 2019 the obligation covers B2C as well. The only exception is for "minimi"/forfettari who invoice private consumers: technically they should, but the AdE has a de facto moratorium on enforcement.
What happens if I issue a "old-style" invoice (PDF) by mistake?
A penalty of €250 to €2,000 per irregular invoice kicks in (art. 6 D.Lgs. 471/1997). For forfettari, the penalty is reduced by half.
Does an invoice to a foreign client (e.g. a German customer) go through the SdI?
No. Invoices issued by an Italian entity to a foreign entity (non-reverse-charge operation) DO NOT go through the SdI. They remain in PDF + traditional registration. The SdI applies only to Italy → Italy operations (and to internal reverse charge, see D.L. 119/2018).
Can I use non-Italian software?
Yes, as long as the XML file complies with the technical specifications published by the Revenue Agency. Several foreign providers (e.g. those integrating with SAP, Oracle, NetSuite) are compatible, but you need an SdI-accredited intermediary for transmission.
Does e-invoicing apply to the forfettario regime?
Yes, since 1 July 2022 (the obligation was already in force from 2019 for forfettari exceeding €25k turnover, extended to all in 2022).
