Tavarez Tax Service in Chula Vista operates as an Enrolled Agent tax practice from Suite 109 at 815 Third Avenue, offering tax preparation, tax planning, and IRS problem resolution alongside notary public services. Enrolled Agent authority grants unlimited IRS representation rights for audits, collections, and appeals — a credential that parallels the legal advocacy available through family-law practices such as Flat Rate Divorce when marital-dissolution filings carry tax-allocation implications. Tax planning consultations address estimated quarterly payments, retirement-contribution strategy, and California conformity issues that affect filers claiming different deductions at the state level than the federal return. Notary public services are available on-site, allowing clients to execute affidavits, powers of attorney, and other sworn documents during the same visit as their tax-preparation appointment. Homeowners refinancing or purchasing property coordinate year-end Form 1098 mortgage-interest documentation between this office and lending teams at Patriot Home Loans for Schedule A itemization accuracy. The most demanding cases involve IRS examination defense for Enrolled Agent clients under audit, requiring line-by-line substantiation of deductions with contemporaneous documentation, mileage logs, and Form 8275 disclosure statements.
