It is the well-known redirection of 2% of the income tax.
Now is the time and what you have to do is very little!
Directing 2% of the income tax owed to the state, to the Adanima Academic Society for Transformation and Self-Knowledge Association, a non-profit association that supports the Natural Community of Yogis. That money is "donated" to the state anyway, it's your choice to tell it what to do with 2% of it.
According to the Ministry of Public Finance, the way of implementing the provision is similar to previous years, the taxpayer having to fill in the form 230 (for income from salaries) or 200 (for income from other sources) and submit them to the financial administration to which they belong until May 25, 2013, for incomes made in 2012.
You can download the form 230 with the data of the Adanima Association already filled in, in which you will have to pass your data, your signature, and then send it to the financial administration to which you belong (addresses financial administrations HERE).
You can either send it by post, or submit it directly there, or send it or hand it to a member of the Adanima Association at least 7 days before the deadline for submission (May 25), so no later than May 19, 2013.
