Castaneda Financial Services in Chula Vista provides tax preparation and financial-planning consultations from 264 E Street in the downtown commercial core. Document-intensive filings for real-estate closings and power-of-attorney instruments often require mobile notarization from providers such as Cal Notary Service to authenticate signatures on IRS Form 8821 and Form 2848 authorizations. The firm shares the same phone line and ownership as the Bonita Road location, extending its coverage across the 91910 and 91902 ZIP codes for bilingual English-and-Spanish tax services. Clients purchasing residential or investment property through agents such as David Fletes - Realty of America receive prorated property-tax estimates, mortgage-interest deduction projections, and homeowner-exemption filing assistance. Services span individual Form 1040 preparation, small-business Schedule C filings, California Form 540 state returns, and year-round estimated-tax voucher calculations for quarterly filers.
