A major shakeup to the federal student loan system affecting millions of borrowers will take effect July 1.The changes mean some Americans -- especially lower-income borrowers -- will face higher monthly payments on their student loans. Other borrowers will face new limits on loans.Roughly 43 million Americans currently have student loan debt, totaling nearly $1.7 trillion, according to the Office of Federal Student Aid, a division of the Department of Education.Education Secretary Linda McMahon, whose mission is to shutter the department, has said the Trump administration will no longer tolerate American taxpayers taking on the debts that are not their own.The major overhaul of the system is part of provisions within President Donald Trump's signature tax law -- the Working Families Tax Cuts Act -- that passed last year, along with other executive orders targeting the Department of Education.Here’s what borrowers need to know:Fewer repayment optionsDepartment of Education and education experts are touting the Trump administration's student loan overhaul as the biggest change to the portfolio in decades.One of the biggest changes is the end of a Biden-era repayment program called Saving on a Valuable Education or "SAVE." There are currently about 7 million borrowers enrolled in that program, and now they will have 90 days to switch to a new plan to pay back their student debt.STOCK PHOTO/AdobeThere will only be two repayment plans that new student loan borrowers can choose: the Repayment Assistance Plan (RAP) or the Tiered Standard repayment plan. The Education Department says that by phasing out other plans, it will make the process smoother and simpler for borrowers to make their payments on time.But student loan advocates warn monthly payments under the RAP plan will be higher for borrowers. The Institute for College Access & Success (TICAS) found that the median U.S. household could see student loan defaults spike and premiums increase by hundreds of dollars a month.New borrowing limitsAnother big change is a cap on how much money graduate students can borrow. Before this change, students could borrow up to the cost of their tuition and fees.As of July 1, graduate students pursuing Master’s degrees will only be able to take out federal loans up to $20,500 per year or $100,000 in total.Professional students, which includes law school or medical school, will be able to borrow up to $50,000 per year or $200,000 total.There are also new limits on Parent PLUS loans, which is now a $65,000 lifetime limit on loans to parents for their children to attend college. In all, most graduate borrowers will not be allowed to take out loans exceeding $257,500.Popular ReadsEducation experts who spoke to ABC News emphasize that the Trump administration's limits could significantly curtail graduate student borrowing or force some borrowers to forgo graduate education altogether.Clare McCann, the policy director at the Postsecondary Education & Economics Research (PEER) Center, told ABC News that it’s conceivable that some graduate borrowers won't achieve their desired degrees."This may end up being a bit of an overcorrection," McCann said. "We could see implications for student access."Meanwhile, the Education Department argued that these new caps will "curb excessive borrowing and force institutions to evaluate their costs." Department of Education Under Secretary Nicholas Kent told ABC News that the caps will ensure higher education is more affordable for millions of Americans."Affordability is the name of the game right now," Kent said. "These loan caps will put downward pressure on institutions to lower their costs. We've got to get the cost of higher education down in this country. We've got to make the system less cumbersome, less complex, [and] easy to understand."Secretary of Health and Human Services (HHS) Robert F.

The Education Department claims the application will take 10 minutes to complete.The Department of Education building is seen in Washington, D.C., Nov. 18, 2024.Jose Luis Magana/AP, FILEKent, the education department under secretary, urged students to get back into active repayment because broad student loan forgiveness that was once promised to borrowers isn't going to happen."[Borrowers] have a responsibility as somebody who took out a loan to repay it," Kent said. "It's not your neighbor's job to repay your loan, it's your job to repay your loan, but there are tools available to help you to make sure that you have a manageable payment."
