"Shnayim Mikra Ve'Echad Targum" should be completed on the day of Shmini Atzeres, but no later than the night following Simchas Torah. The reading of Mishneh Torah performed during the Tikun of Leil Hoshana Rabbah does not count toward fulfilling this obligation.
Summary
One must complete Shnayim Mikra VeEchad Targum for the Torah portion by Shmini Atzeres or, at the latest, Motzaei Simchas Torah; earlier readings during Hoshana Rabbah do not suffice.
