John R Collura Accountancy Corp — incorporated in California with Janice M. Collura now listed as CEO, CFO, and registered agent on the Secretary of State record — operates from the Midtown Hillcrest corridor at 3535 Fourth Avenue as a four-person CPA practice. The firm handles full public-accountant work including general-ledger maintenance, monthly close, and federal and California return preparation, and probate and fiduciary filings get routed alongside the estate counsel at Dillingham & Associates when a 1041 follows a settled estate. Long-tenured individual clients make up a substantial share of the book, with file histories spanning multiple decades of 1040s, amended returns, and rental-property Schedule Es. Small-business engagements skew toward S-corps and partnerships in the service trades — independent contractors, private medical offices, and closely held real-estate LLCs. When investment restructuring drives the tax conversation, capital-gains sequencing gets coordinated with the fiduciary advisors at Financial Haus before year-end projections go out. The most complex workflow combines a California non-resident part-year return, a partnership K-1 with multi-state apportionment, and a federal amended return responding to an IRS notice — all built from reconciled books the firm maintains in-house.
