This guide explores the most impactful tax credits available, complete with data-driven insights and expert recommendations.
Understanding tax credits is essential for businesses looking to optimize their financial strategy. In 2026, companies across various industries—including multifamily housing, SaaS, and self-storage—can use tax incentives to reduce their tax burden and improve cash flow.
1. The Section 179 Deduction: Immediate Expensing for Asset-Heavy Businesses
The Section 179 deduction allows businesses to deduct the full cost of qualifying equipment and property in the year of purchase, rather than depreciating it over time. For 2026, the deduction limit is $2.56 million, and it starts shrinking once total qualifying purchases pass $4.09 million (IRS Publication 946). The 2025 figures were $2.5 million and $4 million. Both are indexed for inflation each year.
Industries like self-storage, multifamily housing, and campgrounds benefit greatly from this deduction, as they frequently invest in property upgrades and new equipment.
As an idea a self-storage facility that purchases $1 million in security upgrades and automation software can fully deduct these costs, reducing taxable income immediately.
2. Bonus Depreciation: Back at 100%, and No Longer Expiring
Bonus depreciation allows businesses to write off a large percentage of eligible asset costs in the first year. The rate is 100% for property acquired after January 19, 2025, and that is now permanent. Property acquired before January 20, 2025 stays on the old Tax Cuts and Jobs Act phase-down, which is 40% for assets placed in service during 2025 (IRS Publication 946). The acquisition date decides the rate, not the date you put the asset to work.
Industries such as mobile home parks, hotels, and marinas can use this incentive to rapidly recover costs for large-scale investments like infrastructure improvements. Check out our insights here.
3. R&D Tax Credits: A Major Win for SaaS and Tech Firms
The Research & Development (R&D) Tax Credit provides incentives for companies developing new products, software, or processes. Documentation is the binding constraint on this credit: you need contemporaneous records tying qualified wages and supplies to specific business components, per the IRS research credit guidance.
For SaaS companies and private equity funds investing in fintech, this credit can significantly offset development costs.
4. Energy-Efficient Tax Incentives: Green Savings for Multifamily & Hospitality
The Energy-Efficient Commercial Buildings Deduction (Section 179D) allows property owners to deduct up to $5.81 per square foot for energy-efficient lighting, HVAC, and insulation placed in service in 2025. That top rate requires meeting the prevailing wage and apprenticeship rules; without them the range is $0.58 to $1.16 per square foot (IRS).
Qualifying work covers the building envelope and its major systems:
- Multifamily housing operators can upgrade to smart HVAC systems.
- Hotel owners can install energy-efficient water heating systems.
- Short-term rental hosts can retrofit properties with sustainable lighting.
This window has closed. Section 179D(i) ends the deduction for property whose construction began after June 30, 2026, so anything that broke ground on or after July 1, 2026 does not qualify. Projects already under construction before that date still do.
5. Low-Income Housing Tax Credit (LIHTC): Essential for Multifamily Developers
The LIHTC program offers significant tax credits to developers investing in affordable housing. Credits are allocated by state housing finance agencies from an annual per-capita ceiling that the IRS indexes each year, so the amount available and the competition for it both vary by state.
This is particularly relevant for multifamily housing investors and private equity funds seeking long-term tax advantages while contributing to community development. Want to simplify? See how outsourcing services cut the bookkeeping load.
6. What the 2025 Tax Law Change Settled
The provisions that were scheduled to sunset at the end of 2025 were addressed by the One Big Beautiful Bill Act, signed July 4, 2025:
- The 20% pass-through deduction (Section 199A) is now permanent. The December 31, 2025 sunset was removed.
- 100% bonus depreciation was restored permanently for property acquired after January 19, 2025. Property acquired before January 20, 2025 still follows the old phase-down.
- Section 179 rose to a $2.5 million deduction limit with a $4 million phase-out threshold, both indexed for inflation.
The planning question shifted from beating a deadline to qualifying for the full amount each year.
7. State-Specific Tax Incentives: Hidden Opportunities for Niche Industries
Many states offer additional tax credits that benefit niche industries:
- Florida & Texas: Neither taxes personal income, which helps owners of pass-through entities. Both still tax the business itself: Florida charges corporations 5.5% (Florida Department of Revenue), and Texas charges a franchise tax on revenue above $2.65 million for 2026 and 2027 (Texas Comptroller).
- California: Green energy tax incentives for marinas and hotels adopting solar power.
- Wyoming: Cryptocurrency-friendly tax policies benefiting blockchain startups (Investopedia, 2025).
Tax credits are a powerful way for businesses to keep more of what they earn. Claiming everything you already qualify for, and tracking the dates that switch each rule on and off, is most of the work.

Frequently asked
Questions, answered
What's the difference between Section 179 and bonus depreciation, and can I use both?
Section 179 lets you elect to expense specific assets up to a dollar cap, and it phases out as your total purchases grow, making it geared toward smaller buyers. Bonus depreciation applies automatically to all eligible assets in a class with no spending cap. You can use both: apply Section 179 first to chosen items, then bonus depreciation on the remainder. Under the One Big Beautiful Bill Act (July 2025), Section 179 carries a $2.5 million limit with a $4 million phase-out threshold, both indexed since (2026: $2.56 million and $4.09 million), and bonus depreciation is 100% for property acquired after January 19, 2025.
Is the R&D tax credit the same as deducting research expenses?
No. They are two separate benefits you can claim together. The deduction (under Section 174/174A) reduces taxable income by your research spending. The R&D credit (Section 41) is a dollar-for-dollar reduction of tax owed, calculated on qualified research activities. The 2025 OBBBA restored immediate expensing of domestic R&D, reversing the prior five-year amortization rule. Qualified small startups can also apply up to a set amount of the credit against payroll taxes instead of income tax.
Do tax credits I can't use this year just disappear?
Usually not. Most general business credits, including the R&D credit, fall under the Section 38 general business credit rules, which generally allow unused amounts to carry back one year and carry forward up to 20 years. LIHTC credits are claimed over a 10-year period with their own recapture rules. Section 179 is different: it cannot create a loss, so amounts exceeding business income carry forward indefinitely. Confirm carryover treatment for your specific credit with a tax advisor before filing.
