San Diego Tax Services is a women-owned tax practice in San Carlos at 6977 Navajo Rd, Suite 140, 92119, handling individual and business returns with a focus on accuracy across complex multi-income filings. The firm sits on the Navajo Road commercial strip roughly one mile east of Lake Murray, and its year-round tax-planning consultations address the same estimated-tax and entity-conversion questions that CPA firms at Goldstein & Goldstein handle for San Carlos corporate clients at the next tier of complexity. Individual preparation covers W-2 and 1099 income, Schedule A itemization, home-office deductions, and capital-gains calculations from stock sales and cryptocurrency transactions. Business clients receive S-corp, partnership, and sole-proprietor return processing along with quarterly estimated-tax computations calibrated to both IRS and California Franchise Tax Board deadlines. The practice offers a military-rate adjustment, reflecting the concentration of active-duty and veteran families in the 92119 ZIP who file under combat-zone extensions, PCS-related moving-expense provisions, and state-of-legal-residence election rules. Federal and California return preparation extends to trust and estate filings, including Form 1041 for irrevocable trusts and Form 706 for estates exceeding the federal exemption threshold. The Navajo Road location shares a commercial block with postal and document services at PostNet, where clients handle certified-mail confirmation for IRS correspondence and extension filings. The Cowles Mountain trailhead is less than two miles northeast, anchoring the office within a San Carlos residential base of homeowners and small-business operators.
