How a High-Income Couple Restructured Their Assets Around the OBBBA's Permanent QBI Rules
Sam's List Editorial | 2026-06-06
Tax planning built around a provision that was supposed to expire is planning that needs to be rebuilt. The OBBBA changed the expiration date for Section 199A's qualified business income deduction from December 31, 2025 to permanent. That's not a small adjustment — for high-income pass-through business owners, it changes which structural decisions make sense.
This couple had made several of those decisions in anticipation of the sunset. When the sunset didn't come, Calculated Wealth rebuilt their financial plan from the ground up.
The Clients: $750,000 in Combined Pass-Through Income, Planning Around a Deadline That Moved
Both spouses owned businesses. Combined pass-through income was $750,000 per year. They had been working with an advisor and a CPA to plan around the QBI deduction's scheduled sunset at the end of 2025.
That planning was sensible given what was known at the time. Strategies that look attractive when you get a 20% deduction on qualifying income look different when that deduction disappears. The couple had been positioning both their entities and their investment portfolio around the assumption that 2025 would be the last year of full QBI treatment.
The OBBBA changed that assumption permanently. The deduction didn't sunset. It became a permanent feature of the tax code.
When the law passed, Calculated Wealth initiated a full review of the couple's financial plan — not just the tax pieces, but the entity structure, the investment portfolio, and the long-term projections that underpinned every decision they had made in the prior three years.
The Entity Structure Problem: A C-Corp That Made Sense Under the Old Rules
One spouse ran a management consulting practice — a business that could be classified as a specified service trade or business (SSTB) under Section 199A. The SSTB classification matters because it determines how the QBI phase-out applies at high income levels.
Under the pre-OBBBA rules, joint filers above the SSTB threshold faced a complete phase-out of the QBI deduction for specified service businesses. At $750,000 in combined income, this couple was well above the old threshold.
Several years earlier, the spouse's consulting practice had been restructured as a C-corp. The decision made sense at the time: a C-corp is not a pass-through entity and is not subject to the SSTB QBI phase-out rules. The flat 21% corporate rate was attractive, and with the QBI deduction expected to sunset, locking in the corporate rate felt like the lower-risk choice.
The OBBBA changed the math on two dimensions simultaneously.
First, the OBBBA raised the SSTB phase-out thresholds. The new thresholds under the permanent law provide a higher income ceiling before the phase-out begins — meaning the consulting practice, even if classified as an SSTB, might now qualify for at least a partial QBI deduction that wasn't available before. Verify the specific thresholds with your CPA at publication time, as they may adjust with inflation indexing.
Second, with the deduction permanent, the multi-year value of the QBI deduction for a restructured pass-through entity outweighed the certainty of the flat 21% corporate rate over the relevant planning horizon.
Calculated Wealth, working in coordination with the couple's CPA, modeled the C-corp versus S-corp election under the new permanent rules. The analysis recommended an S-corp re-election for the consulting practice.
The C-corp-to-S-corp conversion has tax implications of its own — built-in gains rules, timing of the election, and transitional tax treatment that the CPA handled. The advisor's role was to model the long-term financial outcome and coordinate the decision into the broader financial plan.
The Portfolio Restructure: Asset Location in a Permanently Lower Tax Environment
The second major change was in the investment portfolio.
The couple's prior asset location strategy had been designed partly around the assumption that pass-through income would lose the 20% QBI deduction after 2025 — which would have pushed their effective tax rate on that income higher. Higher future tax rates on ordinary income favor holding growth-oriented assets in tax-advantaged accounts (where gains compound without current taxation) and more modest, income-generating assets in taxable accounts.
With the QBI deduction permanent, the couple's effective tax rate on their pass-through income is structurally lower than the old model assumed. That changes the calculus on asset location.
Calculated Wealth revised the asset location strategy:
More growth-oriented assets — those expected to appreciate significantly over long time horizons — moved into taxable accounts, where the lower long-term capital gains rate applies upon eventual sale.
More bond-heavy and income-generating allocations moved into retirement accounts, where ordinary income on interest is deferred rather than currently taxed.
The logic: in a permanently lower tax environment on pass-through income, the premium for deferring ordinary income on bonds into retirement accounts is higher. And the cost of holding appreciated equity in taxable accounts is lower, because the reduced effective rate on the pass-through income means the couple has more after-tax cash flow available for new investment.
No specific return projections are represented here. The restructuring was based on the tax treatment of different asset types under the permanent rules, not on any expected market outcomes.
The Multi-Year Plan: Built for Permanence, Not a Deadline
The prior financial plan had a built-in expiration date. Every projection past 2025 carried a footnote: "assumes QBI deduction sunsets."
Calculated Wealth rebuilt the plan on the OBBBA's permanent provisions. The projections no longer carry a sunset assumption. The S-corp structure, the QBI deduction, the asset location strategy — all modeled on the law as it now exists.
The projected lifetime tax liability under the new plan is materially lower than the projection that assumed the sunset — for two reasons. The structural change in the consulting practice entity eliminates the double taxation of C-corp distributions. And the permanent QBI deduction applies to the pass-through income year after year with no expiration horizon.
No specific dollar outcomes are represented. The reduction is directionally significant given the income level and the structural changes made, but the exact figure depends on future income, future law, and future market outcomes that cannot be predicted.
What This Means for Business Owners Who Planned Around the Sunset
If you made entity structure decisions or deferred certain tax planning moves in anticipation of the Section 199A sunset, those decisions deserve a second look.
C-corp elections made to avoid SSTB QBI phase-outs may no longer be optimal under the higher thresholds. Asset location strategies built around a higher future ordinary income tax rate may need to be recalibrated. Retirement contribution strategies that assumed the QBI deduction was temporary now have a permanently extended payoff horizon.
The OBBBA is the biggest structural change to pass-through taxation since the TCJA. Planning that ignores it is planning on stale assumptions.
If you're a high-income business owner whose financial plan was built around a tax provision that just became permanent, it may be time to revisit the assumptions. The most reviewed financial advisors for business owners on Sam's List understand how these changes interact with long-term planning.
