"Mary Ann has been an absolute lifesaver for my rental property portfolio. Her knowledge of depreciation schedules and passive loss rules saved me thousands in taxes last year. She's responsive, thorough, and genuinely cares about her clients."
"I switched to Mary Ann after years of using a big-box tax service and the difference is night and day. She actually understands my S-corp situation and helped me set up a payroll structure that reduced my self-employment tax significantly."
"As a 1099 contractor, taxes used to stress me out every year. Mary Ann walked me through every deduction I was missing — home office, equipment, software subscriptions — and my refund more than covered her fee. Highly recommend!"
"Mary Ann handles both my business and personal returns and does an outstanding job with both. She proactively reaches out before year-end with planning recommendations — that kind of attention to detail is rare and valuable."
"I had a complicated tax year with a job change, stock options, and a home purchase. Mary Ann handled everything perfectly and explained each piece clearly. I never felt lost or rushed. She's my CPA for life."
"Running a restaurant means tight margins and complicated payroll. Mary Ann keeps my books clean and files everything on time. I have peace of mind knowing my finances are in good hands so I can focus on my customers."

Straight answers
General information for Houston-area taxpayers and business owners. Your own facts, records, and filing history change the answer — that is what a consultation is for.
Direct answer: A CPA prepares and files the business and owner tax returns, maintains or reviews the accounting records those returns rely on, and advises on the decisions that change the tax outcome — entity choice, owner compensation, quarterly estimates, and the timing of deductions. Certified Public Accountants are licensed by a state board of accountancy and hold unlimited representation rights before the IRS.
Direct answer: Anyone may call themselves an accountant. "CPA" is a protected title: Certified Public Accountants are licensed by state boards of accountancy after passing the Uniform CPA Examination and meeting education, experience, and continuing-education requirements. The IRS grants CPAs, attorneys, and enrolled agents unlimited representation rights, so a CPA can represent you in an audit, a collection matter, or an appeal.
Direct answer: Yes. The IRS identifies certified public accountants, attorneys, and enrolled agents as the three credentials with unlimited representation rights, meaning they may represent any client on any tax matter — audits, payment and collection issues, and appeals — whether or not they prepared the return. Representation is authorized on Form 2848, Power of Attorney and Declaration of Representative.
Direct answer: Fees depend on scope rather than a fixed menu: how many returns are filed, the entity type, how many states are involved, whether the bookkeeping needs cleanup before a return can be prepared, and whether year-round planning is included. Ask any Houston CPA to quote from your prior-year return and current records — that is the only way to compare two quotes accurately.
Direct answer: Most single-member LLCs need a CPA once the business is profitable enough to owe quarterly estimated tax, once payroll or 1099 contractors are involved, or once an S corporation election is on the table. Before that point the value is mostly in setting up clean books, so the first profitable year does not have to be reconstructed from bank statements.
Direct answer: Bring last year's filed return, every W-2 and 1099, records of business income and expenses, mortgage and property tax statements, proof of estimated tax payments already made, and any IRS or state notice received. Business owners should add year-end bank and credit card statements plus the accounting file or spreadsheet used during the year.
Direct answer: Mary Ann Hair, CPA works with clients across the Houston metropolitan area, including Cypress, Katy, Spring, Humble, Sugar Land, The Woodlands, Pearland, Clear Lake, Friendswood, Conroe, and League City. The practice is a service-area business rather than a walk-in office: documents are exchanged through a secure client portal and meetings are held by phone, video, or in person by arrangement.
