Our CPA firm in Frederick, MD provides tax preparation, bookkeeping, and CFO-level financial guidance for individuals, small businesses, nonprofits, and over 35 industries throughout Frederick County and the surrounding region. Every return is reviewed by a CPA — never offshored — so you get expert, personal service no matter where you are.
In this short video, Roy Cogliandolo explains the specific strategies we use to lower what our clients owe — and what it would look like to put them to work for your business.
Most CPAs rush through returns without knowing your situation. We combine personal attention with expert knowledge to deliver results others can't match.
Others shuffle you between staff who don't know your history. We know your name, family, and financial situation personally, leading to better tax outcomes every year.
While others rely on junior or even overseas staff, only experienced CPAs review every tax return, catching errors and finding deductions others miss for maximum accuracy.
Most firms avoid complex estate and trust work. We specialize in what others won't touch, handling Non-profit organizations, probate, inheritance, and complex tax situations with expertise.
Other firms disappear after tax season. We're available year-round for questions—from complex planning to simple tax questions, giving you peace of mind always.
Established in 1971, we are proud of our experienced, stable team ready to build long-term relationships you can rely on for decades.
Choose how you work with us, whether with an in-person meeting, Zoom call, or our secure digital portal. We deliver expert tax preparation the way that fits your life, not ours
Stop losing sleep over tax deadlines and deductions. When you work with us, you gain trusted advisors who know you personally, handle everything expertly, and actively work to save you money—creating the financial confidence and peace of mind that transforms how you feel about your entire financial future.
Beyond missed deductions, impersonal tax service creates chronic worry, leaves you vulnerable to costly mistakes, and eliminates the peace of mind that comes from trusted professional relationships. We will meet you for in-person interview or a zoom call, if you prefer. Rather just upload your documents on our portal, we can help you whatever your preference is.

At Mercer Flanagan, we believe in transparent, upfront pricing no surprises. Individual tax returns start at $450. Business tax returns are priced based on several factors that can raise or lower the cost, including business complexity, bookkeeping status, revenue size, and number of state filings. We publish our pricing because we have nothing to hide — see full pricing.
We combine personal relationships with professional expertise. Every client gets a personal CPA interview annually and their tax return is reviewed by a CPA. We don't offshore our tax return preparation like the larger firms do and we provide year-round access for your tax questions.
