Taxwise Accounting Services has operated from 4635 Louisiana Street in San Diego's University Heights since 1985, making owner Billy Edgemon's practice one of the longest-running accounting firms in the neighborhood. Edgemon holds an Enrolled Agent designation and a QuickBooks Advanced Certified ProAdvisor credential, the combination that covers IRS representation authority and expert-level proficiency in Intuit's accounting platform. The firm's small-business focus includes QuickBooks setup, training, and monthly data-file maintenance alongside business and personal tax-return preparation, and the IT infrastructure that supports cloud-based accounting systems connects to the network engineering at Southern Pacific Networks in the same neighborhood. The Louisiana Street office sits between Madison Avenue and Adams Avenue in the 92116 ZIP, within the University Heights grid south of the Adams Avenue corridor. Services include financial-statement preparation, bookkeeping-record review and cleanup, tax-strategy planning, and IRS and state audit representation. The BBB business file dates to March 2001, extending the firm's documented operating history beyond two decades of continuous registration. Edgemon's approach treats the accountant role as a year-round business advisory position rather than a seasonal filing service, with ongoing consultation on entity-choice planning, profit-margin analysis, and cash-flow forecasting. Notarized document needs for business filings and entity formations pair with the mobile notary services at Marilyn's On the Go Notary in the area. The QuickBooks Advanced Certified ProAdvisor credential requires passing Intuit's highest-tier certification exam and completing annual recertification, and the Enrolled Agent status adds a three-part IRS examination covering individual tax, business tax, and representation procedure.
