In typical D.C. fashion, a bill with a name like The One Big Beautiful Bill (OBBB) sounds sunny and straightforward—but for small business owners, the reality is a bit more nuanced.
Now that the legislation is finalized, business owners need to pay close attention to what’s in (and what’s out) of the new tax code. From bonus depreciation to revamped deductions, the changes may not make front-page news—but they could have a very real effect on your bottom line.
At Accounting Complete, we’re already helping clients unpack what the new law means for their 2025 planning. Let’s walk through the top 5 provisions from the OBBB that matter most to small business owners—and how your CPA can help you stay ahead of the curve.
1. Bonus Depreciation Is Back—and That’s a Big Deal
One of the headline features of the OBBB is the return of 100% bonus depreciation. This provision allows businesses to immediately deduct the full cost of qualifying assets—like equipment or vehicles—instead of depreciating them over several years.
This can significantly impact your tax planning and cash flow, especially if you’re considering a large investment in capital assets. It also means your 2025 estimates might need to be updated to reflect a lower tax burden.
This is a win—but only if you plan ahead with your CPA to time purchases and depreciation in a way that benefits your business long-term.

2. Itemized Deductions Are Changing—So Review What’s Allowed
The OBBB includes updates to itemized deductions, consolidating some areas and trimming others. For small businesses, this affects not only your personal return (if you’re a pass-through entity) but also how you structure expenses across the board.
Key changes include:
- Modifications to the home office deduction
- Tightened restrictions on business meals and entertainment
- Shifts in deductibility for certain travel and professional fees
These changes don’t necessarily spell doom—but they do mean that last year’s playbook may not work this year. Sitting down with your CPA before year-end could uncover overlooked deductions—or prevent an audit flag down the road.
3. Greater Scrutiny = Higher Compliance Standards
While the OBBB aims to simplify the tax code overall, the short-term effect for small businesses may be the opposite: higher compliance pressure.
New deduction rules, updated depreciation schedules, and general changes to the tax code often mean that businesses must take extra care in documentation and reporting—especially in the first year of implementation.
CPAs are trained to interpret these changes, align your bookkeeping with the updated code, and ensure you don’t unintentionally land in audit territory.

4. Your Entity Structure Might Not Be Serving You Anymore
Even though the bill didn’t change corporate tax rates, the broader landscape of deductions and credits could shift which business structure is most advantageous for you.
For example, S corps and LLCs will still enjoy pass-through taxation, but changes to depreciation and deductibility might make a different entity structure more tax efficient depending on your industry and growth goals.
If your business hasn’t had a structure review in the last two years, now is the time to re-evaluate. A conversation with a CPA could reveal tax-saving opportunities—or highlight red flags that generic software simply won’t catch.

5. The Only Wrong Strategy Is “Wait and See”
The biggest mistake small business owners make with tax legislation? Waiting until tax season to do something about it.
With the OBBB fully in place for the 2025 tax year, now is the time to update your bookkeeping practices, forecast your cash flow, review your deductions, and talk to your CPA about how to optimize—not just comply.
