One of the most stressful and challenging times for small business owners is tax season, and the worst thing a business owner can hear at the end of a successful year is that a massive tax bill will cut into their impressive profits. In what feels like an instant, a great year full of growth and success can be turned on its head if there has been even a minor oversight in quarterly tax payments or filing paperwork.
Small business owners also have to consider how tax laws may affect their businesses during tax season, as changes can favor or disadvantage them. Ultimately, in 2026, the tax code is firmly on small businesses’ side; however, note that many aspects of the code require business owners to be proactive to take full advantage of its provisions.
Thankfully, small business owners can rest assured that there are not many new tax programs to worry about in 2026. Although this means that there aren’t many new deductions for businesses to take advantage of this tax season, it also means many deductions have not gone away. As a result, if business owners have done the upfront work to prepare themselves for tax season, they shouldn’t be caught off guard.
What the One Big Beautiful Bill Act means for small business owners in tax season
That said, there are a few laws small business owners should consider regarding their taxes, not the least of which is the One Big Beautiful Bill Act (OBBBA). The passage of this law in August 2025 has implications for small business taxes. One of its key impacts is that the 20% small business deduction, which was set to expire at the end of 2025, is now permanent. The OBBBA also makes lower marginal rates and the small business estate tax exemption permanent. Of course, the short-term implications of these changes will not be noticeable; it is simply a matter of maintaining the status quo. However, these changes make the status quo permanent.
The change instituted by the OBBBA Bill that will have the most immediate impact on small business owners is the return of 100% bonus depreciation. After being phased out in 2023, the Bill permanently reinstated the deduction for qualifying property, allowing business owners to immediately deduct 100% of the cost of eligible new or used business property in the year it is put into service. For small businesses, this makes the timing of equipment and asset purchases more important, but it also requires proper documentation and that everything be placed in service correctly.
Even if there aren’t any major legal changes to the tax code, there are some operational changes in enforcement that small businesses should be aware of. Namely, there is clearly a greater focus on compliance and accuracy than ever before. The IRS is paying closer attention to details such as payroll, contractor reporting, estimated taxes, and documentation, especially for small businesses that have grown quickly.
As a result, some small business owners are surprised by balances due because estimated taxes or payroll taxes didn’t keep up with revenue. This is particularly true for businesses that experienced rapid growth or seasonal fluctuations in 2025, as they may forget to adjust their quarterly tax payments accordingly. When they fail to make these adjustments, business owners not only face surprise bills but also penalties and interest.
What small businesses can do to best prepare themselves for tax season
So, what is the best approach for small business owners to take to avoid this type of tax liability? Get organized early. Keep the books current, review payroll and contractor setups, and confirm estimated payments before deadlines rather than waiting until filing time. Waiting until filing time is one of the biggest mistakes a small business can make, as it leads to penalties and higher tax liability and leaves them with less time to address any difficulties that may arise.
Indeed, if small business owners take away one thing, it should be that staying informed about the tax code is a critical, year-round component of business strategy. Even in a tax season like 2026, when there aren’t many new laws with immediate tax implications for small businesses, it is important for business leaders to stay up to date on any changes and how they may affect their businesses.
With the right preparation, tax season doesn’t have to be a stressful time for small business owners. By keeping up with bookkeeping and deductions throughout the year, business leaders can minimize their exposure to additional tax liability and penalties that could hurt their bottom line.
