The Small Business Tax Relief Act would create a two-tier corporate tax rate for small businesses, targeting corporations with up to $5 million in taxable income. The general rate would be 21 percent, while the first $400,000 of taxable income would be taxed at 18 percent.
The bill also tightens tax rules around partnership interests transferred in connection with services, and adds new, complex rules governing investment-management services provided to partnerships. In addition, it expands a self-employment deduction for low- and middle-income filers and raises the excise tax on corporate stock repurchases.

What This Bill Actually Does
The act starts by changing the corporate tax landscape for small businesses. Section 2 amends the tax code so corporations with up to $5 million in taxable income pay a two-tier rate: 18% on the first $400,000 of taxable income and 21% on the rest.
This structure is designed to reduce the tax burden for smaller, genuinely small businesses, while leaving the standard 21% rate in place for larger income levels within the eligible group. The effective date targets taxable years ending after enactment, signaling this as a near-term policy lever for small-business financing and growth.
Beyond corporate-rate changes, the bill introduces major reforms to how partnerships treat transfers of partnership interests when services are performed for the partnership. The changes alter when the partnership interest is included in gross income, and they introduce an election mechanism to manage those transfers.
The goal is to curb compensation schemes tied to services that used to be shielded by existing tax rules.A third pillar is a suite of complex rules for investment-management services to partnerships. Section 710 creates a framework where certain portions of partnership income—especially net capital gains tied to investment services—are treated as ordinary income, with several subrules on allocation, dividends, and capital interests.
The rules also address the disposition of partnership interests, the treatment of qualified capital interests, and related-party issues to reduce avoidance.The package also adds an enhanced deduction for lower-income individuals under Section 164, increasing the share of taxes that can be deducted for those with AGI under $400,000. Finally, Section 6 raises the excise tax on corporate stock repurchases from 1% to 1.5%, applying to repurchases after December 31, 2024.
Taken together, the bill aims to shift incentives around corporate structure, investment management, and share repurchases while expanding tax relief for smaller businesses.

Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Graduated corporate tax rate for small businesses
Sec. 2 amends Section 11(b) to establish a two-tier rate for small corporations. Taxable income up to $400,000 is taxed at 18%, while income above that threshold is taxed at 21%, but the structure applies only to corporations with up to $5,000,000 in taxable income. The effective date specifies the changes apply to taxable years ending after the enactment date. This creates a stepped relief for smaller firms while preserving the headline corporate rate for larger income levels within the eligible group.
Partnership interests transferred with services
Sec. 3 modifies the rule for including transferred partnership interests in gross income when the transfer is related to services. It redesignates and adds a new paragraph clarifying when such interests are treated as having been transferred for purposes of gross income and how elections under related provisions are applied. The amendment aims to close specific timing and valuation opportunities tied to service-based transfers, with an effective date tied to enactment.
Special rules for investment management services to partnerships
Sec. 4 adds Section 710, creating a comprehensive regime for investment services partnerships. It recharacterizes net capital gains as ordinary income under certain scenarios, addresses the allocation of gains and losses, dividends, and the treatment of qualified capital interests. It also covers dispositions, tiered partnerships, anti-abuse rules, and related-party considerations, all designed to curb tax avoidance by investment management activity and to regulate complex partnership structures.
Enhanced deduction for lower-income individuals
Sec. 5 expands the deduction under Section 164(f) for individuals with AGI under $400,000. The provision replaces the prior floor with a rule allowing three-quarters of the taxes imposed to be deductible for those at or below the threshold, providing greater tax relief for lower-income filers. The text sets the effective date as years beginning after December 31, 2024.
Increased excise tax on stock repurchases
Sec. 6 raises the excise tax on corporate stock repurchases from 1% to 1.5%. The increase applies to repurchases occurring after December 31, 2024, reflecting a policy aim to discourage opportunistic share buybacks and to shore up corporate-tax revenues.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Small C-corporations with up to $5 million in taxable income receive lower rates (18% on the first $400k, 21% above) which reduces tax liability.
Who Bears the Cost
- Investment funds and managers providing investment services to partnerships face new ordinary-income treatment for certain income and more stringent allocation rules, increasing tax obligations and compliance costs.
- Partnerships with complex service arrangements may incur higher reporting and recordkeeping burdens under Section 710 and related rules.
- Tax professionals and accountants may see rising demand for planning and compliance work as firms adapt to the new framework.
Key Issues
The Core Tension
The central tension is balancing aggressive tightening of compensation and investment-structure tax avoidance with the risk of stifling legitimate small-business financing and investment activity, while navigating a highly technical, multi-layered set of rules that will increase compliance costs and create new opportunities for planning—and potential gaming.
The act introduces a sweeping set of rules that will require careful operational changes for many taxpayers. The investment-services regime (Sec. 710) creates a broad and technically intricate framework to determine when income from investment-management services is treated as ordinary income, how gains and losses are allocated, and how qualified capital interests are valued and adjusted.
The rules interact with existing provisions on distributions, 708(b) reorganizations, and 751, and include transition provisions that will complicate cross-year planning. The “family partnership” and related-party provisions add further complexity, potentially expanding who is treated as closely related and when certain preferences apply.
These tensions will test how quickly internal controls, systems, and counsel can adapt. The transition provisions, effective dates, and cross-references to other sections will require close coordination across tax, legal, and finance teams to avoid inadvertent noncompliance or double counting.
