• Federal student loan payments will be due again in roughly two months.
• Interest will start accruing in September and due dates will vary among borrowers, but the government will be lenient regarding late payments.
• Here's what to know.

This October may be a stressful time for many people with federal student loans. After a three-year break, the U.S. Department of Education will start expecting payments again at that point.

Borrowers will get their first bill in September or October, the Department says. From then, they'll have at least 21 days before their official due date.

Yet like all things with student loans, there are some caveats.

Here's what to know.

Interest will start accruing in September

Although federal student loan payments won't be due until October, interest will continue collecting on your debt again on Sept. 1, the Education Department says.

The accrual of interest has been suspended on most federal student loans since March 2020.

Due dates will vary

There will be some variation in due dates among borrowers, depending on their account details, including their payment schedule prior to the pandemic.

You can contact your loan servicer or login to StudentAid.gov to learn your exact due date, said higher education expert Mark Kantrowitz.

Recent graduates, meanwhile, may get even more time if they're still in their grace period, Kantrowitz said. Grace periods usually span six months from graduation.

Borrowers will be given leeway with late payments

What's more, the Education Department has said it will institute a 12-month "on ramp" to repayment, which will run from this Oct. 1 through Sept. 30, 2024.

During that period, borrowers will be shielded from the worst consequences of missed payments.

For example, loans will not go into default and delinquencies will not be reported to credit reporting agencies, Kantrowitz said. Late fees won't be charged, either.

"The 12-month on-ramp is similar to a forbearance in many ways," Kantrowitz said.

But as is the case with a forbearance, interest will continue accruing on your debt while you don't make payments. As a result, Kantrowitz recommends borrowers start repaying their bills, if they can.

"Doing otherwise will eventually hurt them," he said.

Still, consumer advocates say this leeway is essential.

"Borrowers are not ready to resume payments," said Persis Yu, deputy executive director at the Student Borrower Protection Center, in a recent interview with CNBC. "Even if the risk from the virus has diminished, the financial fallout has not."
