Credit reporting
Klarna’s credit reporting policy depends on the plan:
- Pay in 4: Klarna has historically not reported Pay in 4 to credit bureaus in the US for most users, though Klarna has expanded credit reporting and this is changing
- Monthly financing: Typically reported to credit bureaus as installment loans
- Klarna Card: Activity may be reported
When Klarna reports a loan to a credit bureau:
- Late payments can damage your credit score
- Paid-off loans help build credit history
Late payments stay on credit reports for 7 years from the date of first delinquency.
Klarna in the US has been gradually expanding credit reporting — check the loan terms presented at checkout for the specific plan you’re taking.
What happens when you miss a Klarna payment
- Auto-pay declined: Klarna retries the payment and emails you
- Continued failure: Loan is marked past due
- Approval restricted: You cannot take out new Klarna loans while you have a past-due loan
- Late fee applied (depending on plan type)
- Credit reporting: If applicable to the loan, the late payment is reported to bureaus
- Extended non-payment: Balance may be referred to collections
Frequently asked questions
Will a missed Klarna Pay in 4 payment hurt my credit? Historically, Klarna’s Pay in 4 has not been reported to credit bureaus in the US for most users, meaning a single missed payment may not directly affect credit. However, this policy is changing — check the terms presented at checkout. And extended non-payment can still result in a collections referral that is reported.
Can I get a Klarna payment extension? Klarna offers some flexibility on payment dates through the Klarna app. Options vary by loan type and account history.
Does Klarna charge interest?
- Pay in 4 and Pay in 30 days: No interest
- Monthly financing: Interest may apply, with the APR disclosed before you accept the loan. Some promotional plans offer 0% APR.
