# Autónomo in Spain: 5 Tax Hacks You Need to Know Before Registering

Becoming a freelancer in Spain is notorious for its high fees. Learn how to legally optimize your taxes.

Becoming an *Autónomo* (freelancer/sole trader) in Spain is notorious for its high social security fees and complex quarterly tax returns. But if you know how the system works, you can legally optimize your taxes.

## 1. Claim the "Tarifa Plana" (Flat Rate)
If you haven't been an Autónomo recently, you are entitled to the *Tarifa Plana*. You pay a flat rate of around €80/month for your first 12 months instead of €300+.

## 2. Deducting the Right Expenses
You can deduct expenses directly related to your economic activity, like software subscriptions and part of your internet bill. You must have an official *Factura* (invoice).

## 3. The Home Office Deduction
If you work from home, you can deduct a percentage of your utility bills by declaring your home office space on your Modelo 036/037.

## 4. Don't Miss the Quarterly Deadlines
Spain does not wait for an annual tax return. You must file VAT (IVA) and income tax (IRPF) returns every quarter. 

## 5. Hire an Accountant
Hiring an accountant (Gestor) costs around €50-€80 a month, and their fee is fully tax-deductible!
