On Palomar Street in Chula Vista's western corridor, A & A Bookkeeping handles individual and small-business tax preparation for W-2 wage earners, independent contractors, and sole proprietors near the Broadway intersection. Federal and California state return filing covers Schedule A itemized deductions and earned-income tax credit calculations, a client mix that frequently overlaps with the immigration-law caseload at Talamantes Immigration Law Firm APC when ITIN filers need coordinated legal and tax guidance. Return preparation extends to California Form 540 adjustments for state-specific withholding reconciliation and nonresident-source income apportionment. Bilingual service capacity supports the South Bay's Spanish-speaking workforce alongside document-preparation offices such as Dina's Immigration Services that serve the same community. Complex filings include multi-schedule 1040 returns with Schedule D capital-gains worksheets and Form 8949 cost-basis reconciliation for investment accounts.
