Even if you bring your account up to date, missed or late payments will stay on your report for 6 years. It has less impact the older it gets and you can usually recover from them over time.
Missed payment
Even when you’ve already paid, missing a payment will still show on your report as "Missed payment'. Most likely your score will go down when it's added.
Late payment
Paying late reflects the same on your credit report as a missed payment. When you pay late it's missing a payment date as agreed with the provider.
