The great American institution, the IRS, has an Israeli equivalent. It's called מַס הַכְנָסָה (mahs hakh-nah-SAH) - literally, income tax.
לְהַכְנִיס (le-hakh-NEES) is to insert or to cause to come in - so its noun form is הכנסה - income.
מַס is a Biblical Hebrew word that means something to the effect of forced labor force (not too far away from slavery).
There are those who see the institution of מס הכנסה as a slavery of sorts - !אַל תִּסְתַּבֵּך עִם מַס הַכְנָסָה (ahl tees-tah-BEKH eem mahs hakh-nah-SAH!) don't get mixed up with מס הכנסה! Listen and repeat.
My experience with them, however, has been quite positive. I have found them - at least when dealing with my case - to be forthcoming, offering a high standard of customer service. I'm also proud to be paying taxes in the Jewish State, regardless of the politics that direct the money.
