Orange Tax & Reg in Chula Vista operates a multiservice office at the corner of Orange Avenue and Third Avenue, combining income-tax preparation with DMV vehicle-registration processing, notary-public services, and certified translations. The vehicle-registration desk handles renewals, out-of-state transfers, salvaged-title processing, and instant plate-and-tag issuance — a scope that overlaps with the ITIN and immigration-filing services at Infinity Tax & Immigration Services, since registration and tax filings frequently coincide for new California residents. Federal Form 1040 and California Form 540 individual returns, along with small-business Schedule C filings and bookkeeping, round out the tax side of the practice. Power-of-attorney preparation and notarization for IRS representation engage the same legal-documentation pipeline used by Arroyo Law Center when tax disputes advance to formal proceedings. The registration operation processes California DMV REG 343 title-transfer forms, REG 256 non-operation certifications, and smog-certification verifications required under California Bureau of Automotive Repair guidelines.
