Our company "ORION AUDIT" (ORION), starts publishing the periodic update (in electronic format) "Account & Tax Report", which will be accessible online for free.

We will try to publish this magazine every two months, within the following month.

In this effort, apart from ORION's executives, excellent columnists also participate, who offer their knowledge for free.

In the Journal's subject matter, we will try to highlight more "timeless" and less "current" issues, as we believe there is sufficient information on the latter.

We thank the Journal's columnist friends.
We thank the tax-accounting information portal taxheaven.gr, of which we are a "Scientific Partner", for the undivided support in
"dissemination" of the Journal and for the material from the "Archive of Laws and Decisions" which is the largest and most complete tax archive in Greece.

Finally, we thank all colleagues for the acceptance and we hope to be useful in the dissemination of knowledge, which we are attempting.
