Jarum Stone

Jarum Stone works with business owners, entrepreneurs, and high-income professionals who want to be more intentional about how they approach their taxes. His focus is heavy equipment leasing and helping clients understand and implement strategies available under current tax law. What makes Jarum’s approach different is that he doesn’t just talk about these strategies—he uses them himself. He currently owns three heavy equipment leasing LLCs and is building a fourth, giving him firsthand experience with what it takes to structure and manage these investments. Jarum works directly with high-income individuals and also partners with CPAs, financial advisors, and wealth professionals who are looking for additional planning opportunities for their clients. He believes tax planning should be an ongoing part of financial strategy—not something that starts when April rolls around—and that the best strategies are the ones you understand, believe in, and are willing to use yourself.

About Stone Advisory Group

Most high earners overpay the IRS every year.

Not because they're careless, because nobody ever showed them the strategies the tax code already rewards. That's the gap I close.

I help business owners, entrepreneurs, and highly compensated professionals earning $500K or more legally reduce their tax exposure using strategies most CPAs never bring up.

My focus: heavy equipment leasing- one of the most powerful year-one deductions available under current law, structured and executed by a tax law firm.

I don't just sell this strategy. I run it myself.

I currently own three heavy equipment leasing LLCs, with a fourth in progress this year. When I walk a client through how this works, I'm describing something I've personally lived, including the parts the IRS cares about most. Legal, not aggressive.

There's a distinction most people miss: tax evasion is illegal. Tax avoidance, using the code exactly as Congress wrote it, is completely legal. Everything I do lives firmly on the legal side of that line. Contracts are built and executed by a law firm, the strategies are written directly into the tax code, and none of them appear on the IRS's list of abusive shelters.

Who I Work With

I work two ways:

Directly with high earners who are tired of watching a large share of their income go to taxes and want a proactive plan, not a scramble every April.
Alongside CPAs, wealth advisors, and financial planners who need stronger strategies to bring to their best clients.

If your only tax conversation happens in April, you don't have a strategy, you have a filing service. Let's fix that.
