Picture the scene. It’s the second week of August, you log into KDP to check last month’s numbers, and the royalty that should have landed in your account simply hasn’t. No email announcing a ban. No dramatic termination notice, the kind that gets screenshotted and shared with a wall of shocked-face emojis. Just… nothing. A silence where money used to be.

Every KDP author’s first assumption, in this order, is: sales collapsed, the algorithm has quietly buried me, or my account has been flagged for something I didn’t do. All three may be wrong. What actually happened is far less personal, and far more bureaucratic—which somehow makes it worse.

What people reasonably assume

Given Amazon’s history of unexplained account terminations and royalty clawbacks—a genre of horror story with its own dedicated corner of the internet—most authors who hit a missing payment default to catastrophic thinking.

Terms-of-service violation. Manipulation flag. The kind of email that starts “We regret to inform you” and ends your publishing career on the spot.

What actually happened

From 1 August 2026, Amazon extended its Payment Service Provider rules to KDP accounts using bank details added before 10 November 2025. Authors who had received an action-required notice were told to update their information by the August deadline to remain eligible for royalty payments and to continue publishing.

The rule affects accounts using a Payment Service Provider—or PSP—that is not enrolled in Amazon’s programme, accounts that have not completed the necessary know-your-customer verification, and some authors whom Amazon has told to use a deposit-taking bank instead.

If your money arrives through an ordinary deposit-taking bank—HSBC, Barclays, Bank of America and the like—you should be unaffected. If you use a cross-border payment service, check it rather than panic. Amazon’s current participating list includes familiar names such as Wise and Payoneer, alongside a long tail of regional providers most authors have never heard of.

Being on that list does not necessarily end the matter. A participating provider must also complete Amazon’s required verification, and an individual author may still be asked to take action. The provider’s name is therefore only the first check, not a magical all-clear.

And it isn’t only the money. Amazon’s own help pages say that affected accounts can lose both the ability to receive royalties through the bank account and the ability to publish until the verification is completed or the payment method is replaced. No new titles. No updates to existing ones. For anyone running a launch, a promotion or simply trying to fix a typo in a blurb, that is considerably more troublesome than one delayed payment.

Investigation, and what to rule out

This is not a sales collapse. It is not an algorithmic penalty. It is not a content or copyright strike. It is a payments-compliance measure, sitting in the unglamorous territory of identity checks, fraud prevention and banking eligibility.

The problem isn’t secrecy. The programme has been sitting visibly in Amazon’s help documentation for months. The problem is that nobody reads payment-plumbing paperwork until the plumbing stops working.

Where the boundary of certainty sits

Amazon says it will notify affected authors if action is required, and the Getting Paid section of the KDP account should display an error or warning. If there is no warning, Amazon says no action is required.

Reports from authors suggest the notification has not always arrived with the urgency the deadline deserved, or that a recognised provider still appeared to require additional verification. Those are individual reports rather than proof of a universal failure, but several authors have described the same confusion publicly.

The practical lesson

Log into KDP. Go to Account Settings, then look in Getting Paid for a warning about your bank account or payment method.

1. If there is no warning, Amazon says no action is required.
2. If there is a warning, check whether your provider appears on Amazon’s current participating-PSP list.
3. If the provider is participating, check the verification status with the provider. Amazon says a completed review can take up to 24 hours to appear in KDP.
4. If the provider is not participating—or Amazon has told you that only a deposit-taking bank is acceptable—replace the payment method with an eligible account.

Do this even if nothing looks wrong yet. Payment infrastructure is the least interesting part of publishing right up until the moment it silently switches itself off, and Amazon’s phrase “may be required to update your bank account” is the sort of sentence that rewards paranoia.
