An AICPA and California Society of CPAs member firm, Stroberg & Associates serves La Mesa's Grossmont area from Suite 107 inside the seven-story Allied Plaza office building on Alvarado Road. Individual and business tax preparation covers Schedule C sole-proprietor filings, Form 1120-S S-corp returns, and Form 1065 partnership allocations—returns that require coordinated banking relationships with institutions such as Mission Fed Credit Union for estimated-tax transfers and payroll-deposit verification. Bookkeeping services maintain accrual- and cash-basis ledgers with monthly bank reconciliation and vendor-payment tracking. Incorporated in California in 2015, the firm handles entity-election filings including Form 2553 for S-corp status, Form 8832 for check-the-box classification, and California Form 3536 for LLC annual-fee estimates, working alongside business-development consultants like DSI Development on growth-stage financial modeling. Year-end engagements include Form 1099-NEC contractor reporting with California Form DE 542 cross-referencing to satisfy both IRS and EDD independent-contractor audit requirements.
