Registering as Autónomo in Spain: 2026 Quotas, Taxes & Digital Laws

The 2026 Autónomo Landscape: Income-Based and Digital-First

Registering as an autónomo (self-employed worker) in Spain has undergone a massive digital transformation in 2026. Beyond the traditional tax registration, you are now entering a real-time reporting environment governed by the VeriFactu system. Whether you are a digital nomad, a consultant, or a local business owner, compliance in 2026 requires certified software and a precise understanding of your “Rendimientos Netos” (Net Income).

2026 Social Security Quotas (RETA)

Spain continues to use the “Real Income” system introduced in 2023. You must estimate your annual net profit and select a corresponding contribution band. In late December 2025, the government announced a freeze on quota increases for 2026, keeping rates stable to assist with economic recovery.

Important Note on MEI: The Intergenerational Equity Mechanism (MEI) has increased to 0.9% for 2026. This is automatically factored into your monthly quota by the Social Security office, but it represents a slight rise in the “invisible” cost of your contributions.

The July 2026 VeriFactu Mandate: No More Excel Invoices

The biggest operational shift for 2026 is the mandatory implementation of VeriFactu. As of July 1, 2026, the Spanish Tax Agency (AEAT) no longer accepts invoices generated via Word, Excel, or uncertified PDF templates.

1. Certified Software: You must use an AEAT-certified billing system that ensures “immutability.” Once an invoice is issued, it cannot be deleted or altered.
2. QR Codes and Fingerprints: Every invoice must now feature a QR code. This allows the recipient (and the tax office) to instantly verify the authenticity of the document.
3. Real-Time Reporting: While you can choose to store records locally, the “VeriFactu Mode” allows for automatic, real-time transmission of every invoice to Hacienda, which significantly reduces your audit risk profile.

The €80 Flat Rate (Tarifa Plana) and Regional Bonuses

For those registering for the first time in 2026, the Tarifa Plana remains the most significant incentive. You pay just €80 per month for the first year.

• The Year 2 Extension: In 2026, you must manually request the extension for months 13 to 24 via the Import@ss portal. This is only granted if your income stays below the SMI.
• The “Zero Quota” Regions: If you register in Andalusia, Madrid, or Murcia, these regional governments may reimburse 100% of your first year’s quotas. In our 15 years of handling visa audits, we have found that timing your registration with these regional grants can save you over €960 in your first year.

Quarterly Taxes: IVA and IRPF in 2026

As an autónomo, you act as a tax collector for the Spanish state. You must manage two primary taxes every quarter:

• IVA (VAT): Usually 21%. You collect this from clients and pay it to Hacienda via Modelo 303. In 2026, the threshold for “reverse charge” for EU B2B services remains strict; ensure you have a valid VIES/ROI number before invoicing European clients.
• IRPF (Income Tax): Most professionals pay a 20% “on account” payment of their profits via Modelo 130. If you are a new autónomo, you can often apply a reduced 7% retention on your invoices for the first three years to help with cash flow.

The “Crea y Crece” Law: B2B E-Invoicing

While VeriFactu handles the security of your invoices, the Ley Crea y Crece (Create and Grow Law) governs the format. By late 2026, all B2B (Business to Business) transactions in Spain must be done using “structured” electronic invoices (FacturaE or XML). A simple PDF will no longer be legally sufficient for transactions between two Spanish companies.

FAQs

Can I be an autónomo if I have a full-time job (Pluriactividad)?

Yes. If you are already employed and paying into the General Social Security regime, you are eligible for a 50% reduction in your autónomo quotas for the first 18 months, followed by a 25% reduction for the next 18 months.

What are ‘Gastos de Difícil Justificación’?

In 2026, the “Hard to Justify Expenses” deduction remains at 7% of your net profit, capped at €2,000 per year. This is an automatic deduction that does not require specific receipts, designed to cover minor business costs.

Can I deduct my home office expenses in 2026?

Yes, if you have registered your home address as your place of business with Hacienda (Modelo 036). You can typically deduct 30% of the proportional cost of utilities (water, gas, electricity, internet) based on the square footage of your office space.
