Autónomo cuota & tarifa plana 2026: Year 1 vs. Year 2

What the tarifa plana really costs a new autónomo

Starting out as a self-employed worker (autónomo) in Spain, the scariest line in your budget is usually the monthly Social Security contribution — the cuota. You have probably seen the headline figure "€80 a month" and also "€88.64," and wondered which is real. Both are: one is the legal flat rate, the other is what actually leaves your account.

This guide walks through exactly what you pay in Year 1 versus Year 2 of the autónomo cuota tarifa plana 2026, the deadline most people miss when extending it, and what happens when the flat rate finally ends. The goal is simple: no surprises on your bank statement.

One honest note up front: this is general information, not legal or tax advice, and the figures change every year. The authority that sets and collects your cuota is the Tesorería General de la Seguridad Social (TGSS), and applications go through its Importass portal (importass.seg-social.es). Confirm your own numbers there or with a gestor before you act.

How much is the autónomo cuota with the tarifa plana in 2026?

The tarifa plana is a reduced flat contribution for people registering as self-employed for the first time. Its legal base for 2026 is €80 per month.

But in 2026 every autónomo also pays the MEI (Mecanismo de Equidad Intergeneracional), a mandatory surcharge that funds future pensions. For 2026 the MEI rate rose to 0.9%, which pushes the real flat-rate payment to €88.64 per month.

So the answer to "how much do I pay?" is:

• Legal flat rate: €80/month
• What you actually pay in 2026: €88.64/month (€80 + MEI)

The MEI keeps climbing on a fixed schedule, so even though the €80 base stays put, your flat-rate cuota will nudge up each year:

Who can get the tarifa plana?

You qualify if you are registering in the RETA (the special self-employed regime) for the first time, or if you have not been registered as an autónomo for at least two years before your new start date. If you already used the flat rate in the past, that gap stretches to three years. There are specific rules for company directors and for family members already working in the business, so check your case with the TGSS.

What do you pay in Year 1 vs. Year 2?

This is where most people get tripped up, because the two years look identical on paper but are governed by completely different rules.

Year 1: the guaranteed €88.64

For your first 12 months, you pay the flat rate — €88.64/month in 2026 — regardless of how much you earn. No income test, no paperwork beyond your initial registration. This period is unconditional.

Year 2: only if you stay under the SMI

For a second 12 months, you can keep paying the same reduced cuota, but only on one condition: your net earnings in Year 1 must have stayed below the annual minimum wage (SMI).

For 2026 the SMI was set at €1,221/month across 14 payments = €17,094 per year (a 3.1% rise approved by the Council of Ministers on 17 February 2026 and applied retroactively to 1 January). If your Year 1 net income came in under that figure, you're eligible for the extension.

If you earned more than the SMI in Year 1, the second-year discount is off the table and you move to the standard bracket that matches your real income.

Here is the practical difference:

Why is the Year 2 extension so easy to lose?

Because it is not automatic. This is the single most expensive mistake new autónomos make: assuming that if they meet the income condition, Social Security applies the extension by itself. It does not.

You must actively request the extension through the Importass portal before your first 12 months are up. Miss the window and you are moved straight onto the standard cuota for your income bracket — which can be two to five times higher.

How to apply for the extension, step by step

1. Note your deadline. The request must arrive before month 12 ends. If you registered in January 2025, your deadline is 31 January 2026.
2. Log in to Importass at importass.seg-social.es using Cl@ve, a digital certificate, or SMS identification.
3. Complete the extension form, including a declaración responsable — a responsible declaration stating your Year 1 net earnings did not exceed the SMI.
4. Submit and save the receipt (justificante) as proof.

Set a calendar reminder for month 10 or 11. The portal will not chase you, and there is no grace period once the flat rate lapses.

What happens when the tarifa plana ends?

Once your flat-rate period is over (after one or two years), you enter the real-income contribution system. In 2026 there are 15 brackets based on your monthly net earnings (income minus deductible business expenses), split into a reduced table for lower earners and a general table above roughly €1,166.70/month.

Here is a simplified map of the 2026 brackets:

Two things make this system more flexible than the old fixed cuota:

• You choose your bracket by forecasting your net income, and you can change your contribution base up to six times a year as your earnings shift.
• If you under- or over-estimate, it gets corrected later through regularización: after you file your income tax return, the tax agency sends your real net earnings to the TGSS, which compares them to what you paid provisionally and issues either an extra bill (if you paid too little) or a refund (if you paid too much). Any extra Social Security you pay is a deductible business expense in the year you pay it.

The takeaway: keep a buffer. A refund is pleasant, but a top-up bill you didn't budget for is exactly the kind of surprise the flat rate was supposed to spare you.

Conclusion

The most useful thing to remember about the tarifa plana in 2026 is that Year 1 is a gift and Year 2 is a task: €88.64/month is guaranteed for the first twelve months, but keeping it for a second year depends on staying under the €17,094 SMI and actively applying through Importass before your deadline. Your next practical step is to find your exact registration date, count forward to month 12, and put a reminder in your calendar now — then confirm your bracket and figures with the TGSS or a gestor.
