Autónomo Tax Calculator (Spain)
Estimate your annual IRPF, IVA, and social security (RETA) as a self-employed worker in Spain. This is a planning tool, not official tax advice.
Assumptions: progressive IRPF brackets are estimated at common national/regional levels and can differ by autonomous community, family status, age, deductions, and tax-year rules.
How autónomo taxes work in Spain
If you are self-employed in Spain, you usually deal with three major tax components: IRPF (income tax), IVA (VAT), and social security contributions (RETA cuota). A good Spain tax calculator for autónomos helps you see all three together so you can avoid cash-flow surprises.
Most freelancers focus only on invoice totals, but the real number that matters is your after-tax income. You can earn well and still struggle with liquidity if you do not plan for quarterly filings and annual settlement.
What this Spain tax calculator autónomo includes
- Net activity estimate: income minus deductible expenses minus annual social security contributions.
- IRPF estimate: progressive tax applied to taxable income after a basic personal allowance.
- IVA estimate: VAT collected on sales minus deductible VAT paid on business purchases.
- Quarterly planning: rough quarterly equivalent for IRPF and IVA so you can set aside cash monthly.
Understanding each tax component
1) IRPF (Impuesto sobre la Renta)
IRPF is progressive. The more taxable profit you make, the higher your marginal rate. In practice, autónomos usually make advance payments during the year (for example through Modelo 130, or via invoice withholdings when applicable), then reconcile in the annual return.
2) IVA (Value Added Tax)
For many activities, you charge 21% VAT on invoices and later pay the difference between VAT collected and VAT paid on deductible business purchases. If your input VAT is higher than output VAT, you may have a VAT credit depending on the period and regime.
3) Social security cuota (RETA)
Your monthly autónomo cuota is usually fixed month by month according to your contribution base and legal framework. Even in lower-income months, this remains a key recurring cost, so it should always be included in your profit model.
Example scenario
Assume you invoice €45,000 (excl. VAT), with €12,000 deductible expenses, and pay €320/month RETA. Your net activity before personal allowance is much lower than gross billing suggests. Then you still need to settle IRPF and IVA. This is why many freelancers in Spain separate tax money into a dedicated bank sub-account every month.
Quarterly and annual obligations to remember
- Modelo 303: quarterly VAT return.
- Modelo 130: quarterly IRPF advance payment (when applicable).
- Annual income tax return: final IRPF reconciliation.
- Bookkeeping: keep invoices and receipts organized for deductions and audits.
How to improve your tax planning as an autónomo
Track deductible expenses correctly
Many people underclaim legitimate expenses simply due to poor bookkeeping. Software plus monthly reconciliation can reduce mistakes and improve your effective tax position.
Build a tax reserve habit
A practical rule is to transfer a percentage of every invoice payment into a reserve account. The exact percentage depends on your margin and sector, but consistency matters more than precision at first.
Adjust your pricing for real tax burden
If your rates were set without considering IRPF progression, social security, and non-billable hours, your take-home pay may be too low. Pricing should be based on after-tax targets, not gross sales alone.
