Autónomos cuota calculator (2026)

RETA does not wait for late invoices. Before you price clients or quit a salaried job, ballpark the monthly cuota from estimated net earnings. For 2026, Spain extended the previous bracket logic after negotiations stalled — treat this as planning math, then confirm in Importass or with your gestoría.

How to use

  1. Estimate realistic monthly net earnings (not best-case month).
  2. Toggle flat-rate mode only if you are in an eligible early period.
  3. Read contribution base + monthly cuota orientation.
  4. Add a tax buffer on top before you set client prices.

What the tool does

Maps simplified earnings brackets to contribution bases and a monthly cuota estimate.

What the tool does not do

Not official Importass output. Brackets and flat-rate campaigns change — verify before you file.

Tips

  • Use a quiet-month net, not your best month, when stress-testing cashflow.
  • Tarifa plana is temporary — plan the step-up.
  • Change of base is a process; ask your gestoría before you move.

FAQ

Did cuotas change in 2026?
Public reporting indicated the government extended the prior bracket system into early 2026 after talks stalled. Always confirm the table that applies to your alta before you budget.
Is this the official Seguridad Social number?
No. It is orientation so you can plan. Importass / your advisor is authoritative.
What is tarifa plana?
An early-period reduced cuota for many new altas. It is not permanent — model the later step-up or you will underprice clients.
Should I include IVA when estimating net?
Cuota is driven by your net earnings base for RETA, not by charging IVA to clients. Keep IVA cashflow separate from personal net.
Is data uploaded?
No — local only.
