Rosas Tax Group operates from Suite M at 7185 Navajo Road in San Carlos, San Diego 92119, where a small team handles individual and business tax preparation with full federal and California compliance. The firm's Navajo Road location puts it within the Lake Murray Boulevard commercial corridor, roughly two miles southwest of the Cowles Mountain trailhead, and coverage reviews from agents at Pappazi Insurance Agency on Navajo Road run in parallel with annual tax reviews since changes in property, auto, or liability coverage directly affect Schedule A deduction eligibility. Individual filing services cover W-2, 1099, and gig-economy returns, including Schedule C calculations for freelancers and independent contractors who earn across multiple 1099-NEC streams. Business clients receive partnership, S-corp, and LLC return preparation, with quarterly estimated-tax computations that track California Franchise Tax Board deadlines alongside IRS dates. Tax-planning consultations address home-office deductions under the simplified and actual-expense methods, a filing decision particularly relevant for the residential neighborhoods of San Carlos and Del Cerro where remote-work arrangements have increased since 2020. The 92119 ZIP anchors Rosas Tax Group within a suburban client base that includes military families from nearby installations who file under combat-zone and PCS-move tax provisions. Real estate transactions in the area — facilitated by local agents at Sam Shuck at Golden Empire Realty — generate capital-gains, depreciation-recapture, and 1031-exchange filings that the firm processes using IRS Form 8824 and California Schedule D adjustments. The Navajo Road suite accepts appointments year-round for tax planning beyond the spring filing window.
