The time period for requesting la declaracion de la renta 2007 started on 3rd March and it’s dead easy to do over the internet. Go to:
http://www.agenciatributaria.es
then click on
Renta 2007
solicitud de borrador
This will open a new window and you need to fill in your NIE number and name. If you haven’t declared before click on the box ‘no declarante’ and then follow the stages. I think you’ll need to fill in your address.
This will register you with the tax office and they will send you a borrador which is a draft of the tax return. Once you get that you can check it through (if you understand any of it, which quite frankly I don’t!) and then make an appointment through the same webpage to go and talk to someone to help you change it. The government sets up an office (at least where I live) for people to go and talk to someone about their tax return, make any changes and then submit it. I’ve found their advice to be very good and helpful and it’s all provided by the government. No struggling through self-assessment like in the UK!
You can then give them your bank account and hopefully receive the tax rebate a few months later, or alternatively give them your bank account number and watch as the money quickly disappears!
The next year the tax office will automatically send the borrador once the time period of the declaracion has opened.
Good luck!
