Best apps for freelancers in Spain (2026): Declarando, Taxfix, Quipu and Autónomo Simple

If you are an individual freelancer with no employees and no SL, this comparison is for you. Not all these tools are built for your profile. We explain which ones are, which aren't, and why.

TL;DR

For a freelancer with no employees or SL, Autónomo Simple is the most specific and cheapest option: €20/month with guided Modelo 130, 303, 349, 390 and 100, AI scanning and regional deductions. Declarando and Taxfix are better if you prefer someone to do it for you (but cost 2–3× more). Quipu and Holded are excellent for SMEs but unnecessarily complex for simple freelancers.

What does a freelancer without an accountant actually need?

Before comparing apps, we need to be honest about the problem. Most tax tools in Spain are built for accounting firms, for SMEs with employees, or for profiles that include companies. When a simple individual freelancer uses them, they find modules they don't need, unnecessary learning curves, and prices designed for larger businesses.

What a freelancer without an accountant actually needs is quite specific:

  • Modelo 130 calculated automatically — with the exact number per box
  • Guided Modelo 303 — output VAT minus input VAT
  • Modelo 349 if they have EU clients — activated automatically
  • Modelo 100 — Renta simulation with real deductions
  • Regional deductions calculated without manual work
  • PDF invoices with VAT, withholding and international client support
  • Expense tracking with receipt scanning
  • A reasonable price — not that of a full accounting firm

With that in mind, here is the comparison.

For the specific profile

Why Autónomo Simple for freelancers with no employees or SL?

Most of these tools are good. The problem is they're designed for a broad spectrum: accounting firms, SMEs, freelancers with employees, companies. Autónomo Simple is built for one exact profile: the individual freelancer in Spain who wants to understand their taxes, do them themselves, and pay a fair price.

01
The full workflow

Modelo 130, 303, 349, 390 and 100. Every box explained. The exact number before opening AEAT. Nothing to guess.

02
Real deductions

Regional deductions engine (Valencia, Madrid, Cataluña and more) and family deductions calculated automatically. What an accountant often doesn't apply.

03
The right price

€14/month. Not accountant pricing (€40–80) or SME tool pricing. The price of a tool built exactly for you.

Frequently asked questions

What is the best app for freelancers with no employees or SL?
For an individual freelancer with no employees or company, Autónomo Simple is the most specific option. It's designed exactly for that profile: guided Modelo 130, 303, 349, 390 and 100, calculated regional and family deductions, and PDF invoices. No company features you don't need.
What is the difference between Declarando and Taxfix?
Both are online accountant models: an advisor files your taxes for you. Taxfix includes a personal human advisor; Declarando has more self-service tools. Both cost more than double Autónomo Simple. If you want to understand your taxes and do the process yourself, Autónomo Simple is a cheaper and more educational alternative.
Is Quipu good for freelancers?
Quipu is a solid tool, especially if you have an SME or work with an accounting firm. For a freelancer with no employees or complex accounting, it includes more modules than you need and the learning curve is steeper. The base price is similar to Autónomo Simple Pro but rises quickly with additional modules.
Which app helps with Comunitat Valenciana regional deductions?
Autónomo Simple has the most specific regional deductions engine for Comunitat Valenciana: habitual home rent, health, sports, childcare, work relocation, renewable installations and more. They're calculated automatically when you complete your taxpayer profile.
Do I need an accountant if I use these apps?
For freelancers with simple activity (no employees, no real estate, main single activity), many manage everything themselves with Autónomo Simple. For complex situations (SL, multiple activities, inheritance, real estate) we still recommend an accountant for the annual Renta.

Conclusion

There is no perfect app for everyone. There is the perfect app for your specific situation. If you are an individual freelancer, no employees, simple activity — design, development, consulting, content creation, marketing, professional services — Autónomo Simple is built exactly for you.

If instead you want someone to do it for you without worrying about anything, Declarando and Taxfix are good options — at a considerably higher price. And if you have an SME with real accounting needs, Quipu or Holded are the right tools.

The key is not paying for complexity you don't need, nor settling for a tool that doesn't explain what you're signing.
