About the principal
Michael C. Williams, CPA, MS
A Long Island practice built around the questions business owners actually face — from monthly clarity through the eventual transition of ownership.
Practice
Michael C. Williams CPA PC
646-1 Main Street
Port Jefferson, NY 11777
(631) 476-6700
A CPA whose practice is organized around ownership, not tax season.
Michael leads Michael C. Williams CPA PC from Port Jefferson, serving closely held businesses, professional practices, and families across Long Island and the New York metro area. The work spans accounting and reporting, tax planning and compliance, consulting, assurance, fiduciary matters, and ownership transition.
What distinguishes the practice is the through-line. Michael founded Business Equity Solutions, LLC to work with owners on business value and exit readiness, and wrote Business Owners Beware: Sell Your Business Now! for the same audience. That experience informs how the accounting is structured from the first month of an engagement — because the records, the tax position, and the value of the business are the same subject viewed at different distances.
In practice that means fewer surprises. Owners who work with Michael know what their numbers say, what their tax position is before year-end, and what would need to be true for the business to change hands on their terms.

Advisory work focused on business value and exit readiness.
How Michael works
Four commitments that shape every engagement.
Owners deserve to understand their own numbers.
Reports that require translation are not doing their job. Explanation is part of the engagement, not an add-on.
Planning beats reporting.
A return records history. The decisions that change outcomes are made months earlier, with the numbers in front of you.
The business should be worth something without you in it.
Transferable value is built deliberately, over years — not discovered at the closing table.
Straight answers, including the unwelcome ones.
If an audit is not required, or a plan will not work, you should hear that first.
Licensing details, professional memberships, and years in practice are stated only where publicly documented by the firm. Additional credentials will be added on the firm's confirmation.
Start the conversation
The best time to strengthen the business you may one day leave is before the transition is urgent.
