Your BNPL Loans Are on Your Credit Report. Almost No Lender Can See Them.

You have a split-payment plan open, maybe a few, and you want to know one thing: is this helping your credit, hurting it, or doing nothing at all? If you have read that buy now, pay later started showing up on credit reports in 2025, that is true and it is also the least useful half of the story.

The useful half is who can see it. This post covers which provider sends which product to which bureau, why the entries sit outside your score even when they are on your file, and what to do with that when you are choosing between two plans at checkout.

One company changed its mind in 2025, and it was not all of them

Affirm is the company that moved. Experian's own announcement of the change, published March 19, 2025, says "consumers will be able to see on their Experian credit file information on all Affirm loans issued from April 1, 2025 onward."

TransUnion followed. Its April 22, 2025 release covers "all Affirm pay-over-time loans issued from May 1, 2025 onward," naming Pay in 4 and longer-term monthly installments together.

That is a real shift, and it is also the whole list. The Congressional Research Service, in its February 18, 2026 report on BNPL, writes that "credit furnishing by BNPL firms remains inconsistent, with firms often furnishing monthly installment products to credit bureaus," and that "as of the date of this report, only one major firm universally furnishes Pay in 4 data."

For scale, the same report puts Pay in 4 originations at $2.2 billion in 2019 and $43.9 billion in 2023, with CRS estimating $63.3 billion in 2025. Nearly all of that volume is still not being reported by anyone.

On your file is not the same as in your score

Here is the part that gets dropped in the coverage. Experian's announcement says the new reporting "will not be factored into consumers' traditional credit scores in the near term but may in the future as new credit scoring models are developed." TransUnion's release says the same thing about scores.

The two bureaus do not quite agree on lenders, though, and that is worth knowing before you assume anything. Experian writes that "a consumer's BNPL history will be visible to lenders who request to view it." TransUnion writes that the transactions "will not be factored into traditional credit scores nor visible to lenders in the near-term." Same company's loans, two different descriptions of who gets to look.

Equifax is not named in either announcement above, but it built the plumbing first. Its explainer says Equifax "put the infrastructure in place to support the reporting of BNPL 'pay-in-four' loans in February 2022," and that it "has the capability to suppress - or 'hold' - BNPL pay-in-four tradelines from existing scoring models."

The CFPB flagged this fragmentation as the actual problem back when it started. In its blog on BNPL and credit reporting, the Bureau noted that "until recently, few BNPL lenders furnished information about consumers to the nationwide consumer reporting companies," and that some bureaus planned to keep BNPL in specialty files separate from core credit files, where the data "may not be reflected in traditional credit reports and credit scores."

Klarna will tell you exactly what it does not send

If you want the clearest single answer from any provider, it is on Klarna's own US help page. Klarna shares repayment activity for its Monthly Pay over time product with TransUnion and Experian, and lists what it does not share: "Pay in full purchases," "Pay in 4 payments," "Pay in 30 payments," and "Klarna Card activity."

Even for the product it does report, Klarna adds this: "For now, the shared data will not impact your score as it is only visible to you. Other institutions currently are not able to view the payment history on your Pay over time loans through Klarna."

Klarna explained the reasoning in a May 13, 2024 statement. It shares data with bureaus in the UK, it says, and is "not sharing data in the US because the bureaus do not have proper models to responsibly process the data and ensure good consumer outcomes." Its concern is that reporting the 96% of its BNPL users who pay on time into models built for revolving credit could push scores down rather than up.

Sezzle is the odd one out, because it makes reporting your choice. Under the Sezzle Up terms, it is "an optional program that you can enroll in to have Sezzle report payment history on associated Sezzle transactions to one or more nationwide credit reporting agencies." Enrolling is not a one-way benefit: "Sezzle must report both positive and negative results to these bureaus so long as you have an Account with Sezzle."

The score that would count it is not in the wild yet

FICO has built models for this. Its explainer on BNPL scoring, dated March 12, 2026, names them as FICO Score 10 BNPL and FICO Score 10T BNPL, and describes them as "new, purpose-built score versions to incorporate BNPL insights" rather than a retrofit of existing models.

Note the release condition in FICO's own wording: "These models will be made available at the credit bureaus concurrently with BNPL data being made available by the credit bureaus at scale in the credit report." The models are waiting on the furnishing, not the other way round.

When they do land, the movement looks modest. FICO's validation work with Affirm data on over 500,000 consumers found that "85% of BNPL customers experienced score changes of fewer than 10 points," and that "97% of highly active BNPL users (5+ accounts) experienced score changes of fewer than 20 points." A new score version also only matters once individual lenders buy and deploy it, which is a separate and slower thing.

Check your own file instead of guessing

You do not have to take any of this on trust for your own accounts. The FTC's guidance on free credit reports notes that "all three nationwide credit bureaus have permanently extended a program that lets you check your credit report from each once a week for free," and that "only one website - AnnualCreditReport.com - is authorized to fill orders for the free annual credit reports you are entitled to by law."

Pull all three, because they will not match. Look for the provider's name in the list of accounts. If a plan you took out last month is absent from a report, nobody pulling that report is seeing it either.

One asymmetry to keep in mind: where a provider does furnish, it furnishes both directions. Klarna's help page lists late payment and default on Pay over time as shared events alongside on-time ones, and Sezzle Up's terms commit to positive and negative alike.

So compare plans on money, not on credit

The practical upshot is that "this one builds my credit" is not currently a tiebreaker. Almost nothing about a Pay in 4 plan reaches a lender's decision today, and where it does reach the file, it is held out of the score.

What does differ between plans is what they cost, and a flat fee hides that well. Take a $240 purchase.

Plan A charges no fee, four payments across six weeks: $240 total, $60 a payment. Plan B charges a $12 fee across six payments over twelve weeks: $252 total, $42 a payment.

Plan B feels lighter because each payment is smaller, but it costs $12 more. To see how much more in rate terms, divide the fee by the price and scale it to a year: 12 divided by 240 is 0.05, times 52 weeks over 12 weeks gives 0.2167, or an effective 21.7%. That is the arithmetic our BNPL Total Cost Calculator runs across as many plans as you add, sorted cheapest first.

One caution on that number, because it cuts both ways: annualizing a fee over a short plan produces a large-looking percentage from a small dollar amount, which is why we rank by total cost rather than by rate. Use the rate only when you are weighing plans of different lengths against each other.

The regulatory question is still open

None of this is settled. The CFPB's 2024 interpretive rule treated Pay in 4 as a credit card under Regulation Z; the Bureau's own compliance page records that "on May 12, 2025, the CFPB withdrew several guidance documents, including the 2024 BNPL Interpretive Rule."

CRS lists credit reporting among the live questions in Congress, including a bill that would require a study of BNPL and credit reporting. Until something forces the issue, furnishing stays voluntary, and voluntary is why your plan is probably invisible.
