How do I file and pay taxes as an Embassy or Foreign Government employee?

I’m currently working for an Embassy and this is my first time being employed, which started this August. My contract states that they won’t be deducting income tax from my salary because they are tax-exempt. In this case, how do I go about filing and paying my own income tax?

Has anyone here had a similar experience working for an Embassy or Foreign Government? Any tips or advice would be greatly appreciated!
