If you’re considering becoming self-employed in Spain, chances are the first thing you’re looking for is an autonomo tax calculator. It’s the question nearly every one of our readers asks: “How much will I actually pay in taxes if I register as self-employed in Spain?”
This question usually comes from two types of people:
- Foreign nationals planning to establish themselves as self-employed in Spain.
- Spain-based freelancers who are already self-employed and want a clearer estimate.
Most people asking already know their expected gross annual income, often from clients or employers abroad.
If that’s your situation, keep reading. We’ll walk through the factors that shape your tax bill, then you can plug your own numbers into the calculator further down to get a personalised estimate.

Personal factors that influence what you’ll pay in taxes
These factors basically come down to whether you’re married (here we include single, separated, divorced, and widowed people) and the number of children under 25 living with you who don’t have annual income above €8,000 (our calculator assumes children with no income of their own).
We treat a married person as someone whose spouse doesn’t receive income. If you’re married and your spouse does receive income, use the single profile instead — it’ll give you a more accurate estimate.
For single people with children, we assume the children live with both parents as an unmarried couple forming a family unit.
Economic factors that influence what you’ll pay in taxes
The first and most important factor is your expected annual income, before VAT — only the value of your actual work.
Your expenses matter too. This is very personal to each freelancer, and forecasting it isn’t always easy. Generally speaking, the more deductible expenses you have, the lower your tax bill.
For the estimates behind our calculator, we’ve considered two expenses that most self-employed people in Spain carry:
- Advisory costs, estimated at €840/year (€70/month).
- Your Social Security contribution (cuota de autónomo).
Since 2023, Spain no longer uses a single fixed quota for everyone. You contribute based on your real net income, inside a system of 15 brackets. As of 2026, monthly quotas range from €200 (net income up to €670/month) to €590 (net income above €6,000/month), plus a 0.9% Intergenerational Equity Mechanism (MEI) surcharge that applies to every bracket.
If you’re a new autonomo, you likely qualify instead for the flat rate (tarifa plana): a reduced quota of €80/month for your first 12 months, extendable up to 24 months if your net income stays below the Spanish minimum wage (SMI).
The calculator below applies whichever of these two situations matches yours.
Reduction for starting economic activity (20% of net income)
This is the most significant reduction available to new self-employed workers. To qualify, you need to meet two requirements:
- In the 12 months before your registration date, you cannot have carried out any economic activity as a self-employed person, in Spain or abroad.
- More than 50% of your income in your first year as self-employed cannot come from an entity you received employment income from the year before registering.
The second requirement is an anti-fraud measure. It’s designed to stop someone employed by Company A from registering as self-employed to do the same work for Company A while claiming this reduction.
This reduction applies to your first and second fiscal year as self-employed, as long as you meet the requirements. From the third year onward, you can no longer apply it. Read the full explanation on the Tax Agency’s website.
Estimation method or tax regime for these calculations
These estimates don’t apply if you carry out an activity taxed under modules (such as retail trade, hospitality, or taxi driving). They apply only to economic activities taxed under the direct estimation method, regular or simplified.
Nearly all professional activities (teachers, programmers, designers, writers, community managers, YouTubers, etc.) are taxed using the direct estimation method.
What happens to VAT?
VAT isn’t a tax you pay out of your own income, because you charge VAT to your client. For example, if your work is worth €500, you add 21% on top, and the client pays you for your work plus VAT. You then remit the VAT you’ve collected once a quarter through form 303.
Not all the VAT you collect ends up being paid over, though: usually you’ll pay a bit less, because you’re also paying VAT on your own business expenses, and you can deduct that from the VAT you collected from clients.
Put simply: the VAT you have to pay equals the VAT you collect minus the VAT you paid on your own expenses.
Payments on account and personal income tax withholdings
In the profiles section further down, you’ll see the total amount of personal income tax you’d owe annually under different circumstances. But Spanish tax law also uses two other mechanisms to collect tax throughout the year: payments on account, and withholdings.
Payments on account (form 130)
If you run a business activity, such as a shop or a bar (these aren’t subject to withholding), you’ll need to deposit 20% of your income quarterly (income minus expenses).
You’ll also use this mechanism if you carry out a professional activity and your clients are foreign (foreign clients can’t withhold tax for you, since they don’t pay taxes in Spain).
Withholdings (professional activities)
These apply exclusively to professional activities, and only when your client is a Spanish company or fellow freelancer. Your invoice must include a withholding percentage — 7% for new self-employed workers (during your first three years) and 15% for everyone else — that reduces the amount you’re actually paid. These rates remain unchanged for 2026.
For example, if your invoice is worth €1,000 and you’re newly self-employed, your client withholds €70 (7%) and pays it directly to the Tax Agency on your behalf.
In both cases, you’ve already paid specific amounts on account toward your final income tax bill. So when it’s time to file your annual income statement, you subtract everything you’ve already paid through payments on account and/or withholdings from the final amount owed.
Autonomo Tax Calculator (interactive tool)
Instead of picking the closest match from a fixed list of scenarios, use the calculator below to get an estimate built around your own numbers. Enter your expected annual income, marital status, and number of dependent children, then toggle the flat rate and the 20% start-of-activity reduction on or off depending on your situation.
Autonomo Tax Calculator
Estimate your Social Security quota (2026 income-based bracket system) and your annual IRPF based on your income, marital status, and dependent children.
A note on how it works: the calculator estimates your Social Security bracket from your net income, then applies Madrid's combined IRPF scale (state + regional) to estimate your annual income tax. All estimates assume Madrid residency, since regional IRPF rates vary slightly outside Madrid.
It's built for orientation, not a substitute for a personalised calculation from a licensed tax advisor.
