Apple has asked a federal court to let it collect commissions of up to 15% on purchases made through external payment links inside iOS apps, detailing a three-tier structure in the latest phase of its antitrust fight with Epic Games. The proposal would charge 15% for standard apps that normally pay Apple's 30% in-app purchase commission, 10% for developers in the Video Partner Program, News Partner Program and Mini Apps Partner Program as well as subscription renewals, and 5% for developers in the Small Business Program. The filing was submitted Thursday in the U.S. District Court for the Northern District of California, the same day the Supreme Court rejected Apple's request to pause the lower-court process while it reviews whether Apple was in contempt for imposing a 27% fee after being ordered to allow external payment links. Apple's current effective rate on those transactions remains 0% while the district court decides what commission, if any, is permissible. Apple says the proposed fees would let many developers link out profitably while allowing it to recover some compensation for the platform, but Epic argues the rates exceed the Ninth Circuit's guidance that any fee should be tied to necessary costs. Apple also separately asked the court to send both sides to a settlement conference.
