Chase has always let you make a 'same day' payment on your account when it's AFTER 8PM ET of your due date, so it will post as 'on time payment.' But this was only available by calling the number on the back of your card and speaking to specialist.
Now: When making a payment on your Chase credit card through chase.com, And it's after 8 PM ET and today's your due date: Your payment will still be on time. You'll see it on your account tomorrow, and any related fees will be removed before your next statement.
- if you pay between 8-11:59 PM ET, they will credit your account for the date you choose, but you might not see it for 1-2 days.
- Late fee will show up on the account, but reversed - Same as what happens when making a payment with a Chase specialist via phone on the same day as due date after 8PM ET
