IRS-listed acceptance agents with an address in Sacramento

The IRS acceptance-agent list for California (acceptance agents - California, read October 20, 2026) shows 17 agents with a Sacramento address: 17 certifying acceptance agents and 0 acceptance agents (the IRS marks acceptance agents with an asterisk).

The IRS acceptance agent program page compares the two: a certifying acceptance agent helps complete Form W-7, authenticates supporting documents (except foreign military ID cards and any documents for dependents that aren’t passports and birth certificates) and returns them immediately; an acceptance agent helps complete Form W-7 and reviews and mails supporting documents. “Fees for service may vary,” the IRS says. Agents are private businesses; this site has no tie to any of them and earns nothing from this list.

With more than 12 agents in Sacramento, we do not reprint them here; the IRS state list linked above shows each name, address and phone.
