Lee, 52, was convicted of bribing an associate of former President Park Geun-hye and jailed for five years in 2017. He denied wrongdoing, the sentence was reduced and suspended on appeal, and he was released after serving a year.
The Supreme Court then sent the case back to the Seoul High Court, which will rule on it, and the sentencing, on Monday.
Under South Korean law, a jail term of three years or less can be suspended; for longer sentences, the person must serve out the term barring a presidential pardon.
Prosecutors have called for a nine-year jail term.
If imprisoned, the year Lee already served in detention will count toward the sentence, as it is the same case.
Monday's sentencing can be appealed to the Supreme Court.
"In a case sent back by the Supreme Court, there is a narrower range of options for the judges' bench... but it's also true that the Supreme Court can't really touch the final court's sentencing no matter what it is," said Rha Seung-chul, a lawyer not connected with the case.
