What this is and who it is for
What is Autónomotools, in one sentence?
Autónomotools is a platform full of helpful tools and resources for the self-employed (autónomos) in Spain.
Who is this for? Do I need to be an autónomo already?
It is for anyone registered as autónomo in Spain, and for anyone seriously considering it. You do not need an account, a card or a gestor to start.
I am thinking about going autónomo but have not registered yet. Is this useful to me?
Yes - many calculators were made with you in mind! They work with figures you make up as easily as on real ones, so you can find out what a given income would leave you before you commit to anything.
Does this work for autónomos societarios (company owners)?
You can calculate your personal social security burden and estimate your year-end debt, as well as calculate your personal income tax, as an autónomo societario.
The more specialized tools like the price calculator work only for regular autónomos.
I am a "false autónomo" / I only invoice one client. Does anything here change for me?
You can use all the tools like everyone else. We will have helpful resources for your specific situation in the future.
I live outside Spain but invoice Spanish clients. Is this relevant?
These tools are all based on you being registered as autónomo (self-employed) in Spain. They do not work for people whose business is based somewhere else.
I am on the Beckham law / a special regime. Do your calculators apply?
The income tax calculator does not currently apply to Beckham law workers - coming soon.
You can use all the other tools and set the switch from „net“ to „gross“ to still see your income, expenses, and social security burden and then calculate the tax burden yourself.
Who built this, and why should I listen to them?
Pekka is a web developer and designer who has been autónomo in Spain since 2018 and got stubborn about understanding the rules himself. He became so good at it that he is now a respected mentor in several autónomo self-help forums. Learn more about him on the "about" page.
The numbers, and how far to trust them
Where do your figures come from?
From the primary sources: the BOE, AEAT's Manual práctico de Renta, the Seguridad Social's own tables, and each comunidad autónoma's published scale. You will find links to the original sources across the site.
How current are the rates? What year do the calculators use?
The current year, by default, and you can pick another one where a tool supports it. Rules are versioned per year, so a 2026 calculation keeps using the 2026 rules after 2027 arrives.
The Seguridad Social simulator gives me a different number. Who is right?
Usually neither, exactly. The official simulator asks for a contribution base and we work out which base your earnings put you in, so the two agree once the same base goes into both. If they still differ, tell us! That is a bug worth knowing about.
My gestor gives me a different number. Who is right?
Your gestor, if it comes to a decision that matters. They know things about you that a form does not ask, and they potentially carry liability. What we can do is show you how a number is built, so you can ask them a sharper question. Every calculation comes with a "show calculation logic" link which you can share. Should the gestor claim there is a mistake in our calculations, please let us know!
What exactly is not included in the calculations?
We completely ignore IVA (and IGIC in Canarias) because those are "zero-sum" taxes for the autónomo: what they pay in IVA they get back from the tax office, what they charge in IVA they have to forward to the tax office. What's also not included is anything that depends on your particular history rather than this year's figures: carried-forward losses, unusual deductions, and whatever your previous years did to your situation.
Do you handle regional (comunidad autónoma) IRPF scales?
Yes. The autonomic half of IRPF uses your region's own scale, and each region's scale is versioned per year, because several of them change their rates in November or December for the year that is already running.
Do you cover the Canary Islands, Ceuta and Melilla?
Yes, including their own IRPF scales.
Do you handle the annual regularización (what happens when my real income differs from my declared bracket)?
Yes. That is what the social security debt tool (coming soon) is for: it takes what you have paid so far against what you are actually earning and estimates what Seguridad Social will ask for, or hand back, when they square it up.
Do your numbers account for deductions I can claim (family, disability, pension plans)?
You can select some of the most important ones in the tax profile: children, other dependants and the personal circumstances that move your mínimo personal y familiar. You may have further more specialized deductions which are not included here.
What happens to my saved calculations when the rates change for a new year?
Nothing. A calculation is saved for the year it was made for and keeps its own rules, so last year's answer stays last year's answer. Run it again against the new year to see what changed.
I found a mistake in a calculation. How do I report it?
Please do, and thank you. Use the contact form, or leave a comment on the tool itself, and say which figures you entered (or share the "show calculation logic" link with us). Anything you report to us will be handled securely and discreetly, based on our privacy policy.
Free and pro plans
What do I get from a Pro subscription?
You get full access to all tools, guides, calculators and how-to's currently on Autónomotools. You can store your numbers in your Autónomotools account, or just on your own machine. You can share calculations, download your data, and leave comments.
Are there any discounts?
Calculations under Spain's minimum wage (SMI) are free in all the calculators, including the paid ones.
What exactly is free, forever, with no account?
Every calculator on the site is free to use up to the minimum wage. If your net income (what you earn minus what you spend) is at or under the SMI, every calculator works in full, with no account and no card. Several other features are free at any income.
Why is the SMI-level calculation free?
One reason is that someone earning below SMI has to think very hard even about small purchases; also this policy gives potential Pro users a way to test the tools and see what they offer before signing up.
What happens to my free-tier saved calculation if I upgrade later?
It stays where it is and you keep it. Upgrading lifts the cap and the one-calculation limit; it does not move or reset anything you already have.
Can I try a Pro tool before paying?
Yes, as long as the yearly earnings you enter stay below minimum wage (around 16-17k) per year, you can use all calculators in full, no card or signup required.
Is there a free trial?
No.
Is there a monthly plan, or only annual?
Annual only. The low price makes a monthly subscription impractical and would generate unnecessary paperwork.
What happens to my Pro features if I stop paying? Do I lose my data?
You keep all the calculations you saved and you can still read them, download them and delete them. No data is deleted. What you lose is the ability to make new calculations that require a Pro subscription.
Do you offer a discount for students, low earners, or people just starting out?
The use of all the calculators under SMI (minimum wage) is free.
Paying, tax and invoices
Who am I actually paying? Who appears on my card statement?
Our "Merchant of Record" is Paddle. They are who your bank shows and Paddle is who issues your receipt.
What payment methods do you accept?
Whatever our fulfillment partner, Paddle, offers in your country at the moment you check out.
Why is Paddle the seller and not you?
Electronic sales get taxed differently in every single target country - Paddle handles tax, filings, and liability for every one, a near-impossible feat for an indie project.
Why does my total differ from the price shown?
The price we show is the net price. The VAT/sales tax on top depends on where you are and whether you are buying as a business. The checkout shows your total before you pay. We felt that is the fairest way to do it: as an autónom@, you get the VAT/sales tax back, and we can offer the lowest possible price this way.
I am an autónomo with a NIF. How do I avoid being charged Spanish IVA?
Enter your NIF in the Paddle checkout before you pay. If it validates, reverse charge applies and no IVA is added.
Where do I enter my NIF / VAT number at checkout?
There is an "add tax ID" link in the payment frame, above the card fields.
I forgot to enter my NIF and was charged IVA. Can it be fixed?
Paddle usually do this - please contact their customer support.
Where do I get my invoice / factura?
Paddle emails it when you pay. Every Paddle receipt comes with a link to your invoice, which you can download at any time.
Can I deduct the subscription as a business expense?
It is software you use for your business, so we strongly suspect the answer will be yes.
Can I pay in a currency other than euros?
Paddle prices in your local currency where it can.
Is my card data stored by Autónomotools?
No. Your payment data never touches our servers. The payment form belongs to Paddle and the card details go straight to them.
Can I purchase a subscription directly from you via Bizum / bank transfer / SEPA direct debit?
In exceptional cases we may be able to help - contact us.
Account & subscription
When does my subscription renew, and will you remind me?
A year after you joined. Paddle will E-Mail you before it renews.
How do I cancel?
You can cancel from your account page, or from any Paddle receipt.
If I cancel, do I keep access until the end of the paid year?
Yes. Cancelling stops the next payment. It does not cut you off during the year you already paid.
What is your refund policy?
I paid by mistake / twice. What now?
Write to us with the date and we will get it refunded.
I paid but my account never appeared. What do I do?
Make sure you sign in using the E-Mail address you paid with using any of the sign-in options - you should land in your account. If that fails, write to us with the email address.
My card expired and the renewal failed. What happens?
Paddle will retry the charge, and emails you a link to update the card. If this never succeeds, the membership lapses and you drop to the free tier. Your previous calculations will stay intact.
Can I change the email address my subscription is tied to?
Yes, but this is two steps: you need to change address on your Autónomotools account, and the one Paddle's billing goes through.
Can I use the same account on my phone and my laptop?
Yes - that is the main reason to have an account in the first place!
How do I delete my account?
You can delete your account from the "my account" page, or by writing to us.
Your data, storage and portability
Where are my numbers stored: on my device or on your servers?
We offer both options. You can keep calculations in your own browser, or save them to your account if you have a Pro subscription.
What happens to device-stored calculations if I clear my browser or switch machines?
They are gone, and we cannot recover them, because we never had them. That is the price of the private option. If a calculation matters, put it in your account or download it.
Can I share a calculation with my gestor, my partner or a client?
Yes. Every result can be turned into a link that opens the tool with those figures already in it, so the person you send it to sees exactly what you saw, and can change a number and watch it move. What isn't transmitted this way, however, is your expenses or product lists.
Does a shared link expose my personal data to anyone who has it?
It contains the figures you calculated with, but neither your name, your email nor anything else. Anyone with the link can see those figures, so treat it like any other link with numbers in it.
Can I un-share something I shared?
No, because the numbers are directly in the link: it works for as long as somebody has it, the same way a forwarded email does. Do not send one to somebody you would not send a spreadsheet to.
How long do you keep my data if I stop using the site?
Saved calculations stay until you delete them or delete your account.
Dormant accounts are treated based on our privacy policy.
Comments and community
Who can see my comments?
Everybody. A comment sits on a public page and search engines can read it. Feedback you send privately, on the other hand, will be shared with others only with your permission.
Can I comment anonymously?
You need an account to comment, but the account is only an E-Mail address and nothing makes you use your real name. Only we will see your E-Mail address.
Can I delete a comment I posted?
Yes, at any time.
How do you moderate comments?
By hand, and lightly. Things get removed for being abusive, off topic, spam, or confidently wrong about something important.
Scope, limits and the legal line
Is Autónomotools a substitute for a gestor?
No, and we're not trying to be. The numbers presented here are for orientation and financial education. The calculators have been painstakingly tested, but they can still contain mistakes. They are not professional advice. Autónomotools was not programmed by a licensed gestor. Do talk to a licensed professional before making any life-changing decisions.
I need urgent help dealing with the tax office or Seguridad Social. Can you help me?
Usually, unfortunately, no: we are not licensed gestors or lawyers, and you may need to talk to such a person. For general English-language help and recommendations we recommend the Autónom@s & self-employed in Spain group on Facebook.
Is anything here professional tax or legal advice?
No. It is orientation and financial education, built carefully and tested hard, but it is still not advice and does not come with a professional's liability behind it. For 100% binding information, talk to a licensed gestor or lawyer.
Can I use your calculations as evidence with Hacienda or Seguridad Social?
Probably not. They are estimates from the figures you typed, and no authority has any reason to accept them. What they are good for is understanding a number, or a letter from the tax office, before you react to it.
Are you affiliated with Seguridad Social, AEAT or any public body?
No, not in any way. We read what they publish, and we link to it.
What happens if a calculation here turns out to be wrong and it costs me money?
We would want to know immediately (please get in touch!!!), we would fix it, and we would say publicly what was wrong and for how long.
We could not, however, compensate you: the site is a tool, not an advisor, and the terms say so.
That is exactly why the sources are on every page and why we keep saying to check a big decision with a professional.
Languages, access and the site itself
Which languages is the site available in?
Currently only in English. Spanish and German coming soon.
Is all content available in all three languages?
Not yet - but we are working on it.
Does the site work offline?
No. You need an active Internet connection to use the features.
Roadmap, feedback and contact
Will future tools and features that you develop also be available in the pro subscription?
Yes - the plan is to grow the list of bite-sized tools like the pricing simulator or the hourly rate calculator, thus adding more and more value to an already very affordable yearly subscription.
Only if we were to develop very very big changes - features that are basically products of their own - we might introduce new pricing options to reflect the value that those products provide.
However, that will never change what you can access with your Pro subscription.
What tools are coming next?
The list changes, so rather than promise here, the newsletter says what landed and what is next.
Can I request a tool or a feature?
Yes please! Requests genuinely do move things up the list. Several tools on the site exist because somebody asked.
How do I report a bug?
Please report them through our feedback form.
Can I link to, embed or reuse your calculators on my own site?
You are welcome to link to anything, freely and without asking.
For embedding and reuse, please contact us and tell us what you have in mind!
