U.S Chamber: Main Street Businesses Face 2025 Tax Hike Threat

Source: US Chamber

In 2017, Congress passed a permanent reduction to the corporate income tax rate from 35% to 21% as part of the Tax Cuts and Jobs Act. To ensure that pass-through businesses like sole proprietorships, partnerships, and S corporations (i.e., the overwhelming majority of small businesses) weren’t put at a tax disadvantage relative to C corporations, Congress created a new 20% deduction for qualified business income. This deduction is codified at section 199A of the Internal Revenue Code. Unlike the permanent reduction for C corporations, however, the 20% deduction for pass-through businesses is scheduled to expire at the end of 2025.


This 20% deduction effectively operates as a rate reduction for pass-through businesses, with some limitations. If a business owner's income exceeds a certain threshold ($383,900 for joint filers and $191,950 for other filers in 2024), the benefit of the 20% deduction may be limited based on the amount of wages paid to non-owner employees (W-2 wages). Generally speaking, the more W-2 wages a business pays, the greater the deduction that business’s owner(s) can claim.


The U.S. Chamber urges Congress to enact the “Main Street Tax Certainty Act,” which would make the 20% pass-through deduction permanent.

Limiting the pass-through deduction to business owners with less than $500,000 in total income would result in a tax increase on one of the major sources of jobs in our nation, directly hurting workers and the economy.
