Tamar Gozansky was born in Petah Tikva in 1940 to a Russian Jewish family.

Gozansky joined Maki (the Israeli Communist Party), the major part of the Hadash alliance.

She entered the Knesset in July 1990 as a replacement for veteran Hadash MK Tawfik Toubi and retained her seat in the 1992 elections, after which she chaired the Knesset's joint committee on early childhood.

[1][2] She was reelected in 1996, and again chaired the joint committee on early childhood.

Prior to the 2003 election, Gozansky announced that she would not seek re-election, which required a special majority of the party for its veteran representatives in the Knesset.
