In return, Mr. Tsipras and his government are expected to propose other, chiefly structural changes, including some actions that the previous government failed to deliver on, such as a crackdown on tax evasion and corruption.

Such changes, if accepted, might ease the burden on the majority of Greeks who have been hit by austerity over the years, and shift more of it to the rich and privileged who have emerged from the crisis relatively unscathed and who, creditors insist, should shoulder part of the solution.

Indeed, many now expected that the government would propose changes aimed at helping those hit hardest by years of austerity in Greece, perhaps by raising low-income pensions. On Sunday, the changes seemed to be headed in the direction of focusing on a crackdown on tax evasion and corruption, and an overhaul of the public sector, a government official said.

If Greek lawmakers do not like the deal, they can vote it down. The coalition government in Athens has 162 seats in the 300-member House.

Even if the government can navigate the pressures at home, a hazardous series of steps lies ahead before it can gain access to the 7.2 billion euros, or $8.2 billion, Mr. Tsipras is now seeking.

International bailout monitors must conduct a further review of Greek finances before unblocking the rescue funds. Eurozone finance ministers need to assess the proposed overhauls, and it was possible that they could make a decision during a conference call on Tuesday.

But Jeroen Dijsselbloem, the president of that Eurogroup of ministers, could also call another face-to-face meeting on Tuesday, when he is scheduled to address the European Parliament. That parliamentary session is likely to be dominated by the situation in Greece.
