The charges, against Apple chief security officer Thomas Moyer, insurance broker Harpreet Chadha, under-sheriff Rick Sung and captain James Jensen were announced by district attorney Jeff Rosen at a media briefing on Monday.
The indictment accused Sung of retaining four concealed carry weapons permits for Apple's security team until the company bowed to the demand to donate 200 iPads, worth about US$75,000 (A$102,738) to the sheriff's office.
Rosen said the donation was withdrawn "at the 11th hour" when search warrants were issued for the probe in Augsut last year.
Sung, Jensen, Moyer and Chadha will be arraigned on 11 January 2021 at the San Jose Hall of Justice. If convicted, they could be jailed.
Lawyers for Moyer and Chadha said their clients were innocent, and collateral damage in a tussle between Rosen and the Sheriff, Laurie Smith.
