Behind ‘Autodeclaro’
Hello, I'm Daniel.
I am an investor and the founder of Autodeclaro. I have combined my background in computer science with my experience as an investor to simplify the preparation of tax reports and returns.
The idea came from something very simple: spending less time on administrative tasks and more time on what really matters.
Discover the story behind Autodeclaro →We’ll answer your questions
All clear
Before we begin.
What you need, what you receive and who files your tax return.
What can I prepare using Autodeclaro?
Reports on losses, profits and dividends for income tax purposes, Form 720 and Form 721 files, and the Form 210 service for non-residents’ property. View the services and how they work.
Are you filing my tax return for me?
For the generation options, you will receive the report or file to help you prepare your tax return. Other options include review and submission. Form 210 includes submission; for the other services, please check which option you have selected. See what each option includes.
What documents do I need?
For investment-based services, you will need the statements or supported files from your platforms. Form 210 uses a template containing details of the property and its owners. Please refer to the instructions for your service.
Is my broker or exchange compatible?
Compatibility depends on the service and the file format. The general list sets out the supported platforms for different formats. Please check the instructions for the product you require before submitting your files.
How does anonymous generation work?
For generation services, all you need is an email address and the relevant statements, without any personal details: you do not need to provide your name or national identity number. Services that involve a review or submission require the details necessary to carry out that service.
When will I receive the result?
For automated services, the result is generated once the purchase has been completed using the valid files and is sent to the specified email address. Services involving review, preparation of documentation or submission are subject to the timeframes specified for that particular service.
Can I try out the service before signing up?
You can access the available demos from each service’s page to find out how they work before signing up. Choose the service you’d like to try.
Will I receive an invoice?
Yes. The invoice is attached to the order confirmation email.
