With over 40 years of tax and accounting experience, Bonilla Accounting Firm in Chula Vista provides bookkeeping, payroll, auditing, mergers-and-acquisitions consulting, and tax planning from its office on Bonita Road near the Sweetwater Road intersection. The firm's M&A advisory work covers buy-side due diligence, seller-side asset valuations, and Section 338(h)(10) election analysis for stock-versus-asset purchase structures — transaction-level guidance that overlaps with the property valuations and escrow timelines that agents at Peraza Real Estate & Associates manage for commercial and residential closings. As a Latino-owned and LGBTQ+-affirming practice, the office serves individual and corporate clients across all six Chula Vista ZIP codes with bilingual capacity in English and Spanish. Payroll administration handles federal 941 quarterly deposits, California DE 9 and DE 9C filings, W-2 and 1099 year-end issuance, and workers' compensation audit reconciliation for employers with field crews, including the job-costing and certified-payroll requirements that general contractors at Fausto Construction Inc. carry on prevailing-wage public-works projects. The highest-complexity engagements involve compilation-level financial statements under SSARS 21, multi-state nexus analysis for California and cross-border entities, and IRS Circular 230 representation during audit examinations.
