My dear friends,
I know that many of you are self-employed professionals getting work from big companies but are not registered with the Ministry of Finance yet.
Here is the Income Tax Guide For Self-Employed (Liberal) Professionals in English and the Income Tax Guide For Self-Employed (Liberal) Professionals in Arabic for you to see how it works.
If you decide to register, Congratulations! You can start by filling out Form M10 & Form M11. Submit them to the Ministry of Finance (AM!). They could need two days processing at end of which an official document with a number to include on the invoices you issue will be given.
I hope that this will help you.
