A family-run tax and bookkeeping practice for individuals and business owners who value careful work, familiar faces, and professionals who remember what came before.
Most tax offices meet you at this year. We start with the years already on file. Continuity is what allows a preparer to recognize an unusual entry on a W-2, a shift in self-employment income, a property that changed use, or a family circumstance that will change how a return should be built.
Familiarity does not replace the annual work of verifying documents. It sharpens it. Long client relationships give us a place to start — and a reason to ask the questions that matter before a return goes to signature.
Preparation and planning for individuals and families, including changing life circumstances, self-employment income, property, retirement, and other tax situations we can verify together.
Discuss Your ReturnTax preparation, bookkeeping, accounting, payroll support, and financial organization for small-business owners who need their records maintained beyond filing season.
Bring Us the BusinessAssistance with prior-year filings, IRS and state notices, corrections, and other tax problems — within the professional authorization held by the preparer handling the matter.
Show Us the NoticeWe do not promise refunds, specific tax savings, audit outcomes, or penalty relief. Representation before the IRS is limited to what each professional at the firm is authorized to provide.
Rhynes Tax & Bookkeeping Service has served Los Angeles from its office on West Manchester Avenue for decades — quietly, carefully, and largely through the trust of clients who bring back the next generation of their family each year.
Mark H. Rhynes leads the practice today, continuing the individual, family, and small-business tax and bookkeeping work the firm is known for. The office remains at 1522 West Manchester Avenue, and returning clients continue to be met by people who remember their prior years.
A more detailed firm history — including verified founding dates, family roles, and archival material — is being prepared for the full Our Story page and will be published as details are confirmed.
Mark H. Rhynes has extensive experience in operational procedures for financial-service and investment-banking firms. His academic background is rooted in the accounting and economic disciplines at the University of California at Irvine, where he earned a Bachelor of Arts in economics with an emphasis on economic theory and international trade. Mr. Rhynes has also performed accounting coursework at UCLA.
At Rhynes Tax & Bookkeeping Service he leads individual and small-business tax preparation, bookkeeping, and the year-round client relationships the firm is known for. Long-term clients describe an approach built on careful attention, direct explanations, and respect for the years already on file.
The reflections below describe the experience long-term clients have shared with the firm. Individual experiences vary and no specific outcome is implied.
"The kind of tax office where they still remember the year you bought your first house — and the year the paperwork on it changed hands."
"Mark is patient with the questions and honest about what he can and cannot do. That has kept my family with the firm across generations."
"I drive well out of my way to keep filing here. The continuity is worth the trip. When my prior-year information is needed, it is already understood."
Small-business tax and bookkeeping is not a filing-season transaction. Records that are maintained year-round — cleanly, consistently, and by people who understand the prior years — make the current-year return, the lender request, and the next entity decision all easier to answer.
Understand the client, prior returns, and what has changed since the last filing.
Gather and verify documents so the return is built on complete, current information.
Address the return or bookkeeping work with appropriate review before signature.
Maintain secure records and identify what should be revisited next year.
The tools have modernized. The approach has not. Every client — from the family who has been filing with the office for decades to a new business owner preparing a first return — should find the process straightforward and the office reachable.

The starting point for a careful return is rarely the current year's documents alone. Here is what to bring — and why continuity matters.
Marriages, dependents, moves, inheritances, and business changes affect returns in ways that are easier to address early.
The records that matter twelve months from now are not always the ones that feel urgent today. A short guide for owners.
IRS and state notices often reach back several years. A brief walkthrough of what makes those conversations productive.
Whether you are continuing a family filing history, bringing a business to the firm, or addressing a notice that reaches back several years — the first step is a short call or note.
Whether you are continuing a family filing history, building a business, or trying to correct what came before — start with a conversation.
