Ludlow & Harrison, A CPA Corp. in Chula Vista's Third Avenue Village has maintained offices at 311 F Street, Suite 300, since the firm's founding in 2001. Estate and trust tax preparation—covering irrevocable trusts, generation-skipping trusts, and Form 1041 fiduciary returns—dovetails with the trust-formation and estate-planning work at MJ Trust Law across the South Bay. The CPA corporation structure spans individual 1040 preparation, business entity returns for partnerships and S-Corps, non-profit 990 filings, and California property-tax assessments. IRS representation services include audit assistance with document-production responses, tax-resolution negotiations for installment agreements under IRC Section 6159, and penalty-abatement requests citing reasonable cause. International clients requiring foreign-document authentication for treaty-based return positions rely on apostille processing at Document Apostille and Certified Translation | Interdocpro. The firm's highest-complexity engagements involve multi-entity consolidated returns with intercompany elimination entries, passive-activity loss limitation calculations under IRC Section 469, and California apportionment formulas for businesses operating across state lines.
