Founded in 1993, Fimbres Consulting Group in Chula Vista's Eastlake Business Center specializes in tax and accounting services for small and medium-sized businesses engaged in cross-border commerce between Mexico and the United States. The firm's cross-border expertise covers tax equalization services, foreign tax credit calculations on Form 1116, and business-entity formation for companies that operate construction and development projects on both sides of the border — work that often involves contractors such as Cali Coast Construction Inc needing binational payroll-tax compliance. With 11 to 50 employees on Bowsprit Road, the practice handles individual and business tax preparation, payroll processing, and full-cycle bookkeeping for clients ranging from sole proprietors to multi-entity corporate groups with operations in both countries. Businesses that separate payroll administration from their core accounting engage dedicated processors such as Payroll Vault San Diego South Bay while Fimbres Consulting maintains the general-ledger and tax-planning oversight. Highest-value engagements include consolidated Form 5471 filings for controlled foreign corporations, transfer-pricing documentation under IRC Section 482, and California combined-reporting elections for unitary business groups with Mexican subsidiaries.
