H&R Block on Fifth Avenue in downtown San Diego's Gaslamp Quarter is a full-service tax preparation office within the national chain founded in 1955, handling individual, small-business, and self-employment returns at 1354 Fifth Avenue. The office prepares federal and California state filings including 1040, 1120, 1120-S, and 1065 forms with e-filing capability, a process that frequently requires power-of-attorney notarization through mobile services like CannonCan Notary for taxpayers authorizing IRS representation. This Gaslamp location sits between Petco Park and the San Diego Convention Center, serving East Village residents, Gaslamp Quarter business owners, and downtown commuters during both standard and extended filing seasons. Beyond seasonal filing, the office provides year-round bookkeeping advisory, payroll services, and entity-structure consultation for sole proprietors evaluating S-corp election, services that complement the ongoing ledger maintenance handled by firms like Serrano Bookkeeping in the Middletown corridor. Complex return categories include multi-state allocation schedules, rental property depreciation recapture under IRC Section 1250, and IRS examination representation through the company's extended service protection program.
