The U.S. Department of Education said Monday that it would resume collecting payments on defaulted federal student loans beginning May 5, a move likely to affect millions of people who borrowed money to pay for college.

Borrowers in default must ask their loan servicer to be placed into such a program. Typically, servicers ask for proof of income and expenses to calculate a payment amount. Once a borrower has paid on time for nine months in a row, they are taken out of default, Mayotte said. A loan rehabilitation can only be done once.

In a Wall Street Journal op-ed, U.S. Secretary of Education Linda McMahon explained the U.S. Department of Education’s decision to restart collections on federal student loans that are in default — and what comes next for Federal student loan borrowers who are behind on their bills.
