Sabino Bookkeeping & Tax Services operates from Fourth Avenue in downtown San Diego's Gaslamp Quarter, providing bookkeeping and IRS-registered tax preparation for individuals and small businesses. The firm's restaurant-industry bookkeeping tracks daily POS reconciliation, tip-reporting compliance under IRC Section 3121(q), and food-cost percentage analysis alongside the risk-management policies structured through carriers like CMR Risk & Insurance Services Inc for hospitality operators. Tax preparation spans Form 1040 individual returns and Schedule C filings for sole proprietors across San Diego, Chula Vista, La Mesa, and National City. Bookkeeping engagements produce the month-end financial statements and property-income reporting that real estate brokerages like Auker Group Real Estate coordinate with when managing rental-property owner accounts in the Gaslamp district. Highest-value engagements involve full-year catch-up bookkeeping reconstructing twelve months of bank feeds, credit-card transactions, and unreconciled POS deposits into GAAP-compliant financial statements for SBA loan applications.
