Aitax vs Autodeclaro

Overview

Both platforms help Spanish residents generate the Modelo 720 declaration for foreign assets.
Key differences lie in automation, workflow, and user experience.

Workflow and User Interface

Autodeclaro:

• Users must read tutorials, extract data manually, and compile it into text files or spreadsheets
• Files are uploaded as ZIPs; the user then waits for the system to generate the Modelo 720
• Basic automation: applies ECB currency exchange rates, performs simple balance and valuation calculations
• Workflow can feel clunky, slow, and outdated, especially for complex portfolios
• Real estate abroad and some asset types require manual input

Aitax:

• Modern, conversational interface; feels like interacting with a live tax assistant
• Document-first workflow: upload PDFs or Excel statements directly
• AI extracts balances, ISINs, account info, valuations, and real estate automatically
• Automatic currency conversions using ECB rates
• Automatically groups identical assets
• Advanced calculations: balances, quarterly averages, classifications
• Step-by-step guidance and interactive explanations in real time
• Generates technical reports (memorias técnicas) for verification
• Minimal user intervention required; the experience is intuitive and natural, similar to using ChatGPT or a modern LLM
