Tax compliance and thoughtful advice for your business and personal financial life.
O’Brien & Panchuk is a certified public accounting firm providing tax preparation, accounting, and advisory services to businesses, individuals, and families. We take the time to understand your circumstances, ask the right questions, and consider how decisions in one part of your financial life may affect another.
That perspective guides both the work you need today and the planning that can help you prepare for tomorrow. Whether you need ongoing tax support or advice involving several businesses, real estate holdings, and family interests, we bring the details together and explain your options clearly.
We prepare and file federal and state tax returns, review the information behind them, and help you plan for estimated payments and upcoming obligations. As part of that work, we consider how changes in income, investments, ownership, or family circumstances may affect your taxes. We explain the choices available and help you address planning opportunities before important deadlines or decisions pass. The goal is accurate reporting supported by careful analysis and practical advice throughout the year.
Your personal tax return may bring together income from employment, a business, rental properties, investments, retirement accounts, and trusts. We help you understand how those pieces fit together and what changes may mean for your tax obligations. Our work includes return preparation, estimated tax planning, and guidance on the tax effects of decisions such as selling an asset, making a significant gift, or preparing for retirement. When appropriate, we coordinate with your financial advisor and attorney to support your broader plans.
Reliable financial information helps you understand how your business is performing and make informed decisions about what comes next. We provide business tax preparation, accounting support, and advice on ownership structure, how owners are paid, cash flow, and growth. For clients with several companies or properties, we consider how the businesses and their owners affect one another. Depending on your needs, we can work with your existing accounting staff or provide additional support to keep the records and tax reporting coordinated.
A tax notice or unresolved filing issue deserves a clear explanation and a considered response. We help individuals and businesses address audits, outstanding returns, tax balances, penalties, and other matters involving the Internal Revenue Service and state tax agencies. We review the facts, explain the available options, and represent you in communications with the agency. Throughout the process, we help you understand what is being requested, which deadlines matter, and what steps may be needed to resolve the issue.
As your circumstances evolve, your questions may extend beyond annual tax and accounting needs. Our experience in the following areas allows us to provide continuity as you acquire property, expand internationally, transfer ownership, or plan for your family’s future.
Owning real estate brings ongoing accounting and tax responsibilities, along with important decisions about purchases, improvements, financing, and sales. We help rental property owners, investors, and developers address those needs while considering how the properties fit with their businesses and personal finances. When appropriate, we evaluate options such as tax-deferred property exchanges and the timing of depreciation deductions. We explain the potential benefits, costs, and future tax consequences so you can assess a strategy in the context of your plans.
Living, working, investing, or owning a business in more than one country can make tax reporting difficult to coordinate. We help clients understand their U.S. filing responsibilities, including reporting for foreign income, accounts, businesses, trusts, and certain gifts or inheritances. Our work also includes U.S. tax matters for nonresident individuals and foreign owners of U.S. property. Where needed, we coordinate with advisors in the other country and evaluate available relief from double taxation as part of the overall plan.
Selling a business, bringing in a new owner, or transferring it to the next generation involves financial and personal decisions that benefit from early attention. We help you understand the value of the business, compare the tax effects of different arrangements, and consider what a transition would mean for your income and long-term plans. Our work can include business valuation, financial preparation, and coordination with your attorney and other transaction advisors. Planning can begin well before you have a buyer or a firm departure date.
Decisions about gifts, trusts, and inheritances can affect your taxes, your access to income, and the people who will eventually receive your assets. We help families consider those consequences and prepare the related tax returns. Working with your estate-planning attorney and other advisors, we assess how business interests, real estate, retirement accounts, and other assets fit into your plans. We also help trustees and beneficiaries understand their tax reporting responsibilities as assets and income pass between generations.
We work with clients across a range of industries, including construction, real estate, medical and other professional practices, agriculture, and service businesses. We take the time to understand how your business operates so that our accounting support and tax advice reflect the decisions you face.
You may be looking for a CPA to handle your ongoing tax and accounting needs, or you may have a decision ahead that calls for closer attention. An introductory conversation gives us an opportunity to learn about your circumstances, answer questions about our services, and determine how we can help. From there, we explain the appropriate next steps and the scope of the proposed work.

Read article →Our engagements bring together tax compliance, accounting, and advisory services based on your needs. We begin by understanding your circumstances and the decisions ahead, then agree on the scope, responsibilities, and fees. For clients who benefit from ongoing support, that relationship includes regular planning and coordination throughout the year.
Our advisory relationships focus on opportunities across entity structure, tax elections, accounting, transactions, and long-term planning where proactive involvement can materially improve outcomes.
Year-round access to the professional team. Advisory and compliance on an agreed scope, with a predictable monthly engagement fee. The Assessment is how we determine whether that relationship is the right fit.
We take on a limited number of new advisory relationships, the ones where the model creates meaningful value. Multi-entity owners, real estate investors, professional practices, and families who want a year-round partner.
We start with a 15 minute call, or a 30 minute meeting in person or by video, to determine fit and whether we can help. If your needs require a more in-depth scope assessment, where we must review prior returns or additional documents, an assessment fee of $450 applies. The fee is fully credited toward your first engagement if you become a client. Those diagnostic assessments typically result in a formal written proposal covering advisory and compliance services.
