The signing of the One, Big, Beautiful Bill (OBBB) Act on July 4, 2025, represents the most significant overhaul of the tax code since 2017. For the small business community, this legislation provides a much-needed sense of permanence, moving away from the “tax cliffs” that have plagued financial planning for the last decade. By focusing on capital investment and domestic innovation, the Act aims to lower the barrier to entry for entrepreneurs while simplifying complex reporting requirements.
Restoring the Power of Bonus Depreciation
Perhaps the most celebrated provision of the OBBB Act is the permanent restoration of 100% bonus depreciation. Under the previous schedule, bonus depreciation was set to phase out entirely by 2027. The OBBB Act halts this decline, allowing businesses to immediately deduct the full cost of eligible property—including machinery, computers, and certain vehicles—in the year they are placed in service. This is a vital tool for cash-flow management, as it allows a business to reinvest its gross revenue into growth-generating assets while lowering its immediate tax liability.
Doubling Down on Section 179
While bonus depreciation is a powerful tool, Section 179 remains the cornerstone for many small business tax strategies. The OBBB Act has doubled the maximum deduction limit to $2.5 million, with a new phase-out threshold of $4 million.
What makes the OBBB version of Section 179 unique is the expanded definition of “qualified real property.” Small businesses can now use this deduction for improvements to non-residential buildings, such as fire protection, security systems, and HVAC upgrades, at a much higher threshold than previously allowed. This encourages business owners to invest in the safety and efficiency of their physical locations.
The Return of Immediate R&E Expensing
For years, businesses were frustrated by the requirement to amortize Research and Experimentation (R&E) costs over five years. The OBBB Act officially repeals this requirement, allowing for full, immediate expensing of R&E costs. For a small tech startup or a boutique manufacturing firm, this change can mean the difference between a tax bill and a tax refund, providing the liquid capital necessary to hire more engineers or develop new product lines.
Simplifying the 1099-K Maze
The Act also addresses the administrative headache caused by the lower reporting thresholds for third-party payment processors. By establishing a clearer, higher threshold for 1099-K reporting, the OBBB Act reduces the “noise” for micro-businesses and hobbyists, ensuring that the IRS and small business owners are focused on significant commercial activity rather than small, incidental transactions.
Stability for the QBI Deduction
Finally, the OBBB Act provides a much-needed extension for the 20% Qualified Business Income (QBI) deduction for pass-through entities. This ensures that sole proprietors, partnerships, and S-corporations continue to enjoy a competitive tax rate comparable to the flat corporate tax rate, maintaining a level playing field for businesses of all structures.
