MSO Capital Deployment Modeler
A management services organization taxed as a C corporation keeps 79 cents of every dollar it earns, where a pass-through owner in the top bracket keeps 63. That difference is deferral, not savings, until two things happen: the capital is deployed inside the structure, and the corporation is owned outside the estate. This tool compares three paths on your own numbers: no MSO, an MSO you own, and an MSO owned by a trust outside your estate.
Your Assumptions
What the MSO keeps after paying its own staff and costs. Without an MSO, this amount stays in the operating business.
The 2026 federal top rate is 37%.
No for most specified service businesses above the income thresholds. Yes cuts the no-MSO rate to 80% of your top rate.
The federal corporate rate is a flat 21%.
The rest is retained and invested. Retained cash invites the accumulated earnings tax; see the notes below the results.
Illustrative crediting net of policy charges. Grows without current tax. Valued at cash value, not death benefit.
Taxed each year at the corporate rate inside the MSO, or at 23.8% if held personally.
Contributions are made at the start of each year.
Assumes your estate already exceeds the $15 million exemption.
Result
Three Paths, Side by Side
An MSO you own is in your estate, but its stock receives a basis step-up at death, so your heirs can liquidate it without a second layer of income tax. An MSO owned by a trust outside your estate avoids the estate tax but gets no step-up. The last row shows what the trust would keep even if it liquidated the MSO entirely and paid 23.8% on the full value.
What Reaches Your Family, by Year of Death
Chart unavailable in this view. The table above carries the same information.
Each point is what your family would receive, after estate tax, if death occurred in that year. The gap between the lower two lines is the rate advantage alone. The gap up to the top line is what ownership outside the estate adds.
Would an MSO hold up for your business?
The numbers above assume the structure survives examination. That depends on facts this tool cannot see: whether the MSO performs real management functions with its own people, how the fee is priced and documented, whether the retained capital has a genuine business use, how the life insurance is issued and reported, and how the trust that owns the MSO is formed and funded.
Disclaimer:
This tool is for informational purposes only and does not constitute legal or tax advice. It is a simplified model. It assumes constant rates of return and tax, that contributions are made at the start of each year, that death occurs at the end of the final year, and that the estate already exceeds the applicable exemption so the marginal estate tax rate applies. It values life insurance at an illustrative cash value rather than its death benefit, which understates every scenario; actual crediting rates, charges, and death benefits depend on the carrier and policy design. It ignores state taxes, the cost of forming and operating the MSO and the trust, and the accumulated earnings and personal holding company taxes. It assumes the management fee is deductible, arm's length, and respected on examination.
