ATHENS--Greece submitted a draft list of reform proposals to creditors on Friday ahead of a crucial meeting of eurozone finance ministers next week, at which Athens hopes to unlock more financial aid to avert a growing cash crunch.

The list of seven proposals includes promises to improve Greece's budgetary procedures and stamp out tax evasion, a senior government official said, while also tackling what the new Syriza-led government has described as a humanitarian crisis among Greece's poor.

The 11-page letter, also suggests a plan for stretching out the repayment of tax arrears--something Athens hopes will prod indebted households to pay back taxes--and new rules to regulate and tax internet gambling, the official said.

Last month, Greece struck an agreement with its creditors to extend its current EUR240 billion ($263 billion) bailout by another four months. But creditors are waiting for Greece to give details of its reform program before they will release any aid.

In the meantime, as cash reserves dwindle, Greece's new government is scrabbling to meet its debt obligations.

On Friday, Athens met the deadline for repaying the first of several loan repayments worth a total of EUR1.5 billion to the International Monetary Fund in March, a senior government official said, making a EUR310 million payment. Just last week, government officials had raised doubts over whether the country could meet the deadline.

The cash crunch, along with ongoing liquidity constraints faced by Greek banks, makes Monday's Eurogroup meeting crucial.

The government in Athens is hoping that its fresh reform proposals, which include details on implementation and fiscal impact, will be well received by eurozone finance ministers.

Earlier this week Jeroen Dijsselbloem, president of the Eurogroup, dangled the prospect of aid disbursement as an incentive for Greece to press ahead with its reform program. Although Greece stands to receive a loan installment of up to EUR7.2 billion from creditors, it is probable that only a fraction of that amount would be released by the Eurogroup.

It remains far from clear whether the reforms Greece has proposed so far will be enough to satisfy the country's most critical creditors, such as the IMF, Germany and, to some extent, the European Central Bank.

During its meeting Thursday in Nicosia, the ECB's governing council decided not to reinstate a special waiver--suspended in February--that allows Greek banks to pledge junk-rated Greek government debt as collateral for ECB loans. The ECB has made clear that reinstatement of the waiver would come only after Greece's government successfully pressed ahead with reform.

In the meantime, Greek banks have had to rely on a more costly lending facility provided by the Bank of Greece. That emergency lending facility, or ELA, must also be approved by the ECB, which has capped its use. But with Greek banks already pushing up against that cap, the ECB governing council meeting this week agreed to marginally raise the cap by EUR500 million to EUR69 billion.

Bank of Greece Governor Yannis Stournaras assured depositors on Friday that Greek banks were safe. But following a meeting with Prime Minister Alexis Tsipras, Mr. Stournaras also emphasized that Greece needed to reach a "successful" agreement with creditors at next week's Eurogroup meeting.
