Personnal income tax

Thanks thejoker, I appreciate the link.

However, the site only provides forms. There is not even a guideline for the case I wanted to start filling them to estimate my tax. The link "assumes" that you know the rules and regulations of the country.
I need either a lawyer to make a simulation based on my inputs, or to find a sort of a rule of tumb.
Please can anyone reading this give me an approximation of what tax to expect in % whith a gross income in the range of 5'000 to 10'000 USD? Thanks in advance.

Thanks for this feedback.
Have found the info you mention in the mentionned site. However I got some informations that foreighners who chose to retire in the country get some sort of tax relief under certain conditions. I will contact the tax office to find out, but I guess that the Governement structure like in all countries is quite complicated and finding this sort of answer might be quite difficult unless I come down and have a formal meeting.
Would you by chance be aware of any such arrangement possibility?
(for ex in Thailand you are tax free if you have a property and spend a few months in the country every year and have a deposit in a local bank of 40'000 USD)
