As this year comes to a close, business owners seeking to reduce their taxes for 2025 have a variety of opportunities. Here’s a look at two tax-saving tools: bonus depreciation and retirement plan contributions.

Assets Eligible for Bonus Depreciation
First-year bonus depreciation has been given new life under the legislation commonly known as the “One Big Beautiful Bill Act” (OBBBA). It had been scheduled to be only 40% for 2025 (60% for certain long-production assets) and to vanish after 2026. The OBBBA permanently reinstates 100% bonus depreciation for eligible assets acquired and placed in service after January 19, 2025. Acquiring eligible assets and placing them in service by Dec. 31, 2025, could significantly reduce your 2025 tax liability.

Eligible assets include most depreciable personal property, such as:
- Equipment,
- Computer hardware and peripherals,
- Certain vehicles, and
- Commercially available software.
Also eligible is qualified improvement property (QIP), defined as improvements to the interior of a nonresidential building that was already placed in service. QIP doesn’t include costs to change the building’s internal structural framework (such as enlargement). These costs must generally be depreciated over 39 years.
Unlike Section 179 expensing, which is limited to $2.5 million for 2025 (up from $1.25 million before the OBBBA) and subject to a phaseout, the amount of bonus depreciation a taxpayer can claim is generally unlimited. But there are other tax consequences to consider.

Beware of the Excess Business Loss Rule
Individual taxpayers who have losses as a sole proprietor or as an owner of a pass-through entity (partnerships, S corporations, and, generally, limited liability companies) may inadvertently trigger the excess business loss rule when they claim bonus depreciation. The excess business loss rule allows business losses to offset income from other sources (such as salary, self-employment income, interest, dividends, and capital gains) only up to an annual limit. Amounts above that limit are excess business losses. For 2025, this is the excess of aggregate business losses over $313,000 ($626,000 for married couples filing jointly).
Excess business losses can’t be deducted in the current year and must be carried forward to the following tax year. Such losses can then be deducted under the rules for net operation loss carryforwards. As a result, an individual taxpayer’s 100% first-year bonus depreciation deduction can effectively be limited by the excess business loss rule.
Save Taxes by Saving for Retirement

Tax-favored retirement plans can provide significant savings for small business owners, both by building retirement security and by reducing taxes. Contributions are tax-deductible (or pre-tax, if you’re contributing as an employee).
One of the simplest options is a Simplified Employee Pension (SEP) IRA. If you’re self-employed, you can contribute up to 20% of your net income to a SEP IRA, with a cap of $70,000 for the 2025 tax year. If your own corporation employs you, the contribution limit is 25% of your salary, also capped at $70,000. The tax savings can be substantial.
Other options include 401(k)s, SIMPLE IRAs, and defined benefit plans. Depending on your age and income, some of these options might allow you to make even larger contributions. Ask your tax advisor for details.
Wrapping it Up
The permanent restoration of 100% first-year bonus depreciation creates tax-saving opportunities for taxpayers while they expand their business potential. And a tax-favored retirement plan is beneficial for you, your business, and your employees. Every business is different, so it’s essential to consult a tax professional.

As the founder and principal of Russo CPA, P.C, Bob pleasantly surprises clients (plus the IRS and lawyers) with his proactive, caring, and interested approach. Bob’s authentic passion for both numbers and people is why his accounting firm is sought after by everyone from solopreneurs to CFOs. And it’s what energizes his fast-growing team of top CPAs who follow his lead by providing impeccable service to clients – without the CPA geek speak.
The only thing geeky about Bob is his favorite reading material: the latest tax regulations, codes, and rulings (so he can secure every possible tax advantage for his clients). You might mistake Bob for the charismatic entrepreneur and CFO behind an internet travel startup or a visionary real estate developer. That’s because he held those roles during his 30-year career as an accountant, which began at a high-profile accounting firm. While CPAs aren’t required to have “field” experience, the best ones do. But Bob doesn’t define success by his own achievements, it’s what he achieves for his clients. Because of his entrepreneurial past, Bob relates so well to his clients. In addition to serious tax savings most firms would miss, he empowers his clients with real-world accounting and financial insights to increase business.
Bob is even results-driven outside of work, whether it’s finishing the 2012 NYC Iron Man or volunteering for 12 years as President of a kids’ soccer league. While his bottom-line results are always impressive, what matters to Bob are the people who benefit from them.
When he’s not immersed in accounting, Bob is with his family, cooking up elaborate 18-course meals or globetrotting.
