CAP Paper: Tax Code Must Catch Up to Business Income Migration

The 20 percent qualified business income deduction, enacted in 2017 under Section 199A, may no longer be enough to reconcile the US tax code with where business income actually lands. The Center for American Progress argues as much in a new policy paper titled "Business Income Has Moved Beyond Corporations, and Tax Policy Must Follow."

The publication positions an empirical proposition first — that business income has moved — and a policy prescription second: that the tax code must adapt.

What is the argument?

The paper's headline claims both an analytical mismatch and a design failure. The analytical mismatch is that US tax policy debates continue to center the C corporation while the actual distribution of business income does not. The design failure is that credits, deductions, and rate schedules remain drafted primarily for corporate filers.

The argument lands in a year when pass-through reform remains active on Capitol Hill. The 2017 Tax Cuts and Jobs Act carved out Section 199A's 20 percent deduction — the most explicit acknowledgement from US tax law that pass-through income, not corporate income, anchors the modern US business tax base. Treasury regulations and IRS guidance on Section 199A have stayed contested through successive guidance cycles, including the boundary treatments for specified service trades or businesses.

What does this imply for CFOs?

For corporate tax departments, the implication is structural rather than mechanical. Treasury statistics consistently describe pass-through entities — partnerships, S corporations, and sole proprietorships — as the dominant reporting class by count of US business tax returns, even as corporate receipts retain the larger revenue share because of rate and base differences. A reform that rebalances either side of that split alters the calculation behind entity elections, intellectual-property holding structures, and credits currently optimized for corporate filers.

The CFO-level question: which entity decisions made under current law remain durable into the next decade, and which face credible reform risk on either end of the policy spectrum?

What we do not yet have

All that has reached CFO Observer in the source feed is the paper's title and publisher. The underlying document's methodology, supporting figures, and named authors did not appear in the inputs reviewed here. CFO Observer will publish a follow-up with empirical detail and direct quotations from the paper's authors once the full text is available.

For now, the headline alone tells finance leaders where the US tax-policy conversation is moving — toward an explicit recasting of the business tax base around pass-through income rather than the C corporation. Tax directors tracking horizon risk should expect any future reform package to inherit that framing, on either side of the 2017 baseline.
