Ally Financial has extended the cutoff time for accepting check deposits that are credited the next day.

The $156 billion-asset company said that checks deposited electronically by 7 p.m. Eastern time, Monday through Friday, will be available in customers' accounts on the next business day. That is later than the current deadline of 4 p.m. Eastern, according to Detroit-based Ally's website.

Additionally, checks deposited after 7 p.m. Eastern weekdays, or on a weekend or holiday, will be available in customers' accounts on the second business day.

"It's really about being more flexible and convenient for customers, especially those on the West Coast," Andrea Puchalsky, an Ally spokeswoman, said in an email to American Banker explaining the move.

The changes take effect Sept. 15 for deposits made by computer or mobile device, according to a notice sent to Ally Bank customers on Friday afternoon.

Ally Bank only conducts business online and does not operate branches.
