In La Mesa's Casa de Oro district, H&R Block on Avocado Boulevard provides bilingual tax preparation in English and Spanish, including ITIN applications for taxpayers without Social Security numbers. Military-family tax situations — including combat-zone pay exclusions, Thrift Savings Plan contributions, and PCS move deductions — align with the financial products maintained by service members through Navy Federal Credit Union in the same area. Founded in 1955, the chain operates approximately 12,000 offices nationwide; this Avocado Boulevard location staffs bilingual preparers who manage both resident and nonresident California returns. ITIN holders filing with Individual Taxpayer Identification Numbers require specialized W-7 documentation and certified passport copies, which may also appear in immigration-related matters handled by Garmo & Garmo, LLP. California Earned Income Tax Credit eligibility extends to ITIN filers with qualifying children, expanding refund opportunities beyond the federal EITC for residents in the 91941 ZIP. Most complex engagements involve dual-status returns combining Form 1040-NR nonresident schedules with resident-period income allocation and treaty-based position reporting under IRC Section 6114.
