"I want to return to Thailand as an ordinary Thai and don't need to have any position or salary," he told channel TITV.
Thaksin, who has been living abroad since the September 2006 bloodless coup, said he harboured no ill-will toward the generals who deposed him.
"I would invite them to play golf with me. Then, it will be over," he said, adding that revenge would solve nothing.
"What would I get out of it? I might feel gratified but the country would be damaged."
The leaders of the 2006 coup have said Thaksin, who was prime minister for six years and remains popular with the country's rural poor, is welcome to return home but will have to stand trial for corruption-related charges.
On Tuesday his allies in the People Power Party who won 233 parliamentary seats in the country's first election since the coup said they will form a coalition government once three smaller parties joined them.
However, all parties are awaiting an announcement on Thursday from Thailand's election commission which has been probing allegations of electoral violations.
Their findings could change the final numbers of seats won by the competing parties.
