Strategy first, forms second. We ask the questions that find the money — then we handle the paperwork that keeps it.

A family firm. A father, two daughters, and one mission: help entrepreneurs pay as little tax as legally possible.
Our whole approach is asking you questions that most accountants don’t bother to look for. Flip through six of them — each one hides a strategy your current accountant has probably never mentioned.
Do you rent your home to your own business for fewer than 15 days a year?
Under §280A, you can rent your home to your business for up to 14 days a year — for board meetings, planning retreats, company events. The business deducts the rent. The income is tax-free to you personally. Most owners have never heard of it, because nobody asked.
Bring this question to your free assessment →These questions are conversation starters, not tax advice — what applies to you depends on your facts. Finding out is exactly what the free assessment is for.
Four core services, one goal: less tax, legally — planned before the year ends, not tallied after it’s too late to change.
“Tax Planning Transformed into a Profit-Generating Strategy”
Our flagship discipline. Proactive moves made while the year can still change — entity choices, timing, deductions engineered on purpose — instead of an autopsy in April.
“Ensure accurate and timely filing for your personal and business returns.”
Returns prepared by the team that knows your plan, so the strategy actually lands on the filing — personal and business, accurate and on time.
“Record-keeping for business growth and tax efficiency”
Books kept current all year, so every planning conversation starts from real numbers — and tax season stops being a reconstruction project.
“Maximizing your returns when it’s time to move on.”
Timing, structure, and capital gains modeled before you list — because the most expensive exit decisions are the ones made at the closing table.
Some strategies live with specialists. These services come with our vetted partners — brought in when your plan calls for them, coordinated by us.
$9,500 one blueprint · yours to keep
A comprehensive report that serves as the roadmap for your tax savings: every strategy available to you, explained in plain English — what it is, how it works, your projected return on it, its impact on retirement, and the next steps to implement it. Reviewed with you in detail, in a working session.
The plan is the map: return preparation and implementation are separate engagements, scoped after you’ve seen the blueprint.
We review your current books to make sure everything is organized and up to date — and flag any cleanup your numbers need.
Up to your last three years of tax returns and their coordinating financials — P&L, balance sheet, general ledger — hunting for errors and missed opportunities, including possible amendments.
Your current year, reviewed while it can still change.
Your entities and elections, checked against the business you run today.
Each strategy explained in plain English: what it is, how it works, your projected return on it, its impact on retirement, and the next steps to implement it.
How today’s tax picture reads to a lender tomorrow — planned for, not discovered.
We guarantee that your Initial Tax Plan will identify tax-saving opportunities equal to 3 (three) times the cost of the plan, which may apply to the current year or future years, depending on your circumstances. If the identified savings do not reach 3× the cost of the plan, we will refund the portion of the fee exceeding one-third (1/3) of the documented savings.

The Initial Tax Plan is $9,500 — a blueprint for your whole tax picture. It includes a free review of your books, a review of up to three prior years of returns and their coordinating financials, a review of your current year-to-date financials, a structure review, the tax planning strategies available to you, and future borrowing considerations. The report is yours to keep. Return preparation and implementation are separate — the plan is the map.
We guarantee that your Initial Tax Plan will identify tax-saving opportunities equal to 3 times the cost of the plan, which may apply to the current year or future years. If the identified savings do not reach 3× the cost of the plan, we will refund the portion of the fee exceeding one-third (1/3) of the documented savings. The full terms are stated in the plan agreement.
