The reward was announced on Thursday by the Venezuelan police investigations unit.
Gonzalez, who claimed he resoundingly won a presidential election but has been living in Spain after a warrant was issued for his arrest, said he will travel to Argentina this weekend.
Gonzalez's "international tour" comes days ahead of the planned January 10 inauguration of President Nicolas Maduro for his third term.
Gonzalez will meet with Argentine President Javier Milei, who is involved in an escalating diplomatic spat with Maduro's government, at the presidential residence in Buenos Aires, Venezuela's top opposition group said on X.
Gonzalez shared the post, adding "our tour of Latin America begins. First stop: Argentina." It was unclear where else Gonzalez planned to travel.

Electoral authorities and the country's top court say Maduro won the July contest, but have not published full ballot box-level tallies of votes.
Venezuela's opposition, a number of Western countries and some international organisations have decried the election as non-transparent and have called for the full publication of ballots, with some openly labelling the process fraudulent.
The opposition published ballot box-level tallies on a public website, saying they show Gonzalez, who left Venezuela for Spain in October, easily won the contest.
Meanwhile Argentina's government said earlier on Thursday it had filed a complaint with the International Criminal Court against Venezuela for detaining a member of its security forces, calling it a "forced disappearance."
Venezuelan prosecutors say the man is being investigated for alleged links to terrorism.
Venezuela's Foreign Minister Yvan Gil rejected the complaint to the ICC, calling it a "pitiful spectacle," in a post on Telegram.
Tensions between the two South American countries have risen since Javier Milei, a far-right libertarian, assumed Argentina's presidency in late 2023. Relations worsened after Venezuela's contested presidential election.
