Editorial context: this article is part of our practical invoicing series for freelancers. Always adapt recommendations to your country, tax setup, and client type.
Why the Change Is Happening Now
Spain is aligning with the EU push for real-time reporting. The goal is to cut tax fraud and speed up VAT collection. The law was approved in 2022 and the final deadlines were published in late 2023.
Most freelancers will need to switch by July 2025 if they work with companies or the public sector. Private clients may follow later, but many platforms already ask for the new format.
The transition is part of a broader European initiative called ViDA (VAT in the Digital Age). Spain’s implementation follows the same technical standards already used in countries such as Italy and France. By requiring structured data, the tax agency (AEAT) can automatically cross-check invoices against VAT returns and detect discrepancies in real time.
For freelancers, this means the familiar PDF workflow will be replaced by an XML-based file that includes machine-readable fields. The change also supports Spain’s commitment to reduce the VAT gap, which has historically been higher than the EU average. Early adopters report faster payment cycles because clients can process the structured data without manual entry.
Who Must Switch First
- Freelancers billing Spanish companies or government agencies
- Small businesses with annual turnover above €100,000
- Anyone already using electronic invoicing systems for public contracts
If you only invoice private individuals, you still have a short window, but preparing now saves stress later.
The first wave of mandatory adoption targets B2B and B2G relationships. Companies with turnover above €100,000 must comply from 1 July 2025, while smaller entities and freelancers have until 1 January 2026 for most private clients. Public sector contracts already require FacturaE through the FACe platform, so any freelancer working with municipalities or ministries should migrate immediately.
Even if your current clients are individuals, many platforms (marketplaces, coworking spaces, professional networks) are updating their supplier onboarding processes to request FacturaE files. Preparing your workflow now prevents last-minute rejections when these platforms enforce the new requirement.
What the New Invoices Must Contain
The format is called FacturaE. It is an XML file that includes:
- Your tax ID and the client’s tax ID
- Line items with net amounts, VAT rates, and totals
- Digital signature for authenticity
- Structured payment details
Traditional PDFs do not meet these requirements. You need software that can generate and send the correct file type.
FacturaE follows the Spanish national standard (UNE 318001) and is compatible with the European e-invoicing directive. The file contains three main sections: header (parties and dates), lines (products or services with tax breakdown), and summary (totals and payment terms). A qualified electronic signature or advanced electronic seal must be embedded to guarantee integrity and authenticity.
In practice, this means every invoice must carry a unique identifier, the correct VAT rate applied to each line, and the exact IBAN or payment reference. Missing any of these fields will cause automatic rejection by client systems or the public administration portal.
How to Prepare Your Workflow
Start by checking your current tools. Ask three questions:
- Does it export FacturaE XML?
- Can it add a digital signature automatically?
- Will it connect to the Spanish tax portal (FACe) when required?
If the answer to any question is no, plan to move before the deadline.
Create an invoice in Invoicey and test the FacturaE export in under two minutes.
Many freelancers begin by exporting a sample invoice from their existing accounting software and opening it in a free XML viewer. This quick check reveals whether the file contains the required tags. If the structure is incomplete, the next step is to evaluate dedicated e-invoicing platforms that already comply with Spanish and EU rules.
Choosing the Right Tool
Overview
You need software that handles the new Spanish format without extra manual steps. Look for tools that already support EU e-invoicing rules.

Try Invoicey free and see the FacturaE option in the invoice settings.
When comparing solutions, check whether the tool offers batch sending, recurring invoice templates, and automatic archiving. These features become valuable once you are managing dozens of monthly invoices. Also verify that the provider updates its software promptly when AEAT publishes new validation rules or schema changes.
Common Mistakes to Avoid
- Waiting until June 2025 to test the new format
- Forgetting to update client tax IDs in your records
- Using free PDF converters that do not add a valid digital signature
- Ignoring the requirement to keep electronic copies for at least four years
Another frequent error is assuming that any “electronic invoice” solution is automatically compliant. Some tools generate visual PDFs with an attached XML that still lacks the required digital signature. Always request a test file and validate it using the official AEAT validator before sending it to clients.
What Happens If You Do Not Comply
Late invoices can be rejected by clients. Repeated non-compliance may lead to fines starting at €300 per invoice in some cases. The safest route is to switch early and test with one or two clients first.
Beyond financial penalties, non-compliance can damage professional relationships. Large companies often have automated procurement systems that reject non-FacturaE files, causing payment delays of weeks or even months. Public administrations may also block future tenders if your invoicing history shows repeated errors.
Practical Tips From Other Freelancers
Several users who moved early shared these habits:
- Keep a master list of client tax IDs in one place
- Set a monthly reminder to export and archive XML files
- Use the same numbering sequence across all tools to avoid gaps
- Ask clients if they accept the new format before sending the first invoice
One freelancer in Barcelona maintains a shared spreadsheet with every client’s NIF/CIF, preferred invoicing email, and portal login details. Another user in Madrid schedules a quarterly review of archived XML files to ensure the digital signatures remain valid and the files are still readable by current software versions.
