Epperson & Company has provided tax preparation, bookkeeping, payroll, and business consulting from its Park Plaza Drive suite in La Mesa since 2004, specializing in entity formation and controller services. S-Corp and LLC formation packages include EIN application, California Secretary of State filings, operating-agreement templates, and initial board resolutions — organizational documents that may require the notarization and authentication services available through Tower Mobile Notary Services. Controller-level engagements provide outsourced financial oversight, including accounts-payable and accounts-receivable management, monthly close procedures, and variance analysis against budget projections. IRS dispute resolution has addressed multi-year back-tax negotiations, correcting prior-preparer errors through amended returns and establishing installment agreements for outstanding federal and California balances. New-business clients launching in La Mesa's growing commercial corridors coordinate brand-identity development and digital-presence strategy with local agencies including Ukato Marketing, connecting entity-formation accounting to early-stage market positioning. Highest-tier engagements involve multi-entity S-Corp election filings with Form 2553, reasonable-compensation studies, California Form 100S built-in gains calculations, and quarterly payroll tax reconciliations across federal Form 941 and California DE 9 schedules.
