tax calculator spain autonomo

If you are self-employed in Spain (autónomo), planning your taxes is essential. This page includes a practical tax calculator for Spain autónomo and a plain-English guide to help you estimate your annual IRPF, VAT balance, social security cost, and net income.

How taxes work for an autónomo in Spain

Most freelancers in Spain deal with three core tax elements:

• Social security (Seguridad Social): your monthly autónomo contribution.
• IRPF: personal income tax on your business profit.
• IVA (VAT): tax you collect from clients and later settle with the tax agency.

The challenge is cash flow. Even when your income looks strong, IRPF installments, VAT settlements, and monthly social security can create pressure if you do not reserve money every month.

What this tax calculator spain autonomo includes

1) Taxable profit estimate

The calculator starts with your annual invoiced income (without VAT), subtracts deductible expenses, and subtracts your annual social security contributions. The result is your estimated taxable profit.

2) Progressive IRPF estimate

It applies a simplified progressive IRPF structure to estimate annual income tax. This gives a useful planning number, but your final return can differ due to personal minimums, family status, regional rates, and additional deductions.

3) VAT balance estimate

VAT is usually neutral in theory, but it affects real cash flow. You collect VAT on sales and pay VAT on expenses. The difference is what you may need to pay (or recover) when filing VAT returns.

4) Quarterly guidance

You also get an approximate quarterly amount for Model 130 to help prepare for payment periods and avoid last-minute surprises.

Quick example

Suppose you invoice €45,000 per year, have €12,000 in deductible expenses, and pay €320/month in social security:

• Annual social security: €3,840
• Taxable profit: €45,000 - €12,000 - €3,840 = €29,160
• IRPF and VAT are then estimated from that base and your selected VAT rates

This gives you a planning framework before real declarations (quarterly and annual) are submitted.

Common deductible expenses for autónomos

Deductibility depends on activity and documentation, but frequent examples include:

• Professional software and subscriptions
• Office rent or coworking fees
• Business-related transport and travel
• Professional training and courses
• Accounting and legal services
• Equipment used for your activity (according to rules and depreciation if needed)
• Phone and internet proportional to business use

Keep complete invoices and clear accounting records. Good documentation is as important as the expense itself.

Important filing models and deadlines (general overview)

Quarterly filings

• Model 303 for VAT (IVA)
• Model 130 for IRPF prepayments (if applicable)

Annual filings

• Model 390 annual VAT summary
• Renta (Model 100) annual income tax return

Dates can change and exceptions exist, so always verify current deadlines with Agencia Tributaria or your advisor.

Tips to avoid tax stress

• Set aside a fixed percentage of each invoice for taxes the same day you get paid.
• Track income and expenses monthly, not quarterly.
• Use separate bank accounts for operations and tax reserves.
• Review your effective tax rate every quarter.
• Work with a gestor if your activity includes mixed VAT rates, international clients, or complex deductions.

Final note

This calculator is designed to help with decision-making and forecasting. It is not a legal tax opinion. For official declarations, use updated regulations and professional advice based on your autonomous community and personal tax profile.
