Established in 2009, CKYFS Inc. provides tax preparation, business consulting, and Mandarin Chinese-English interpreting from the 1903 Granger Building in downtown San Diego's Bankers Hill district. The firm's business-development consulting pairs with the operational strategy work handled by firms like CAVAlier Consulting, LLC for clients scaling bilingual enterprises across the U.S.-Asia trade corridor. As a veteran-owned firm holding National Association of Tax Professionals (NATP) and California Society of Tax Consultants (CSTC) memberships, CKYFS processes Individual Taxpayer Identification Number (ITIN) applications under IRS W-7 filing requirements for foreign nationals and nonresident aliens. Translated tax documents requiring certified copies route through production partners like RushMyPrints for IRS-submission-ready formatting and secure mailing. Highest-complexity engagements involve concurrent ITIN processing, multi-year back-filed returns, and FBAR reporting for clients with undisclosed foreign accounts entering IRS Streamlined Filing Compliance procedures.
