When tax season wraps up, most business owners in Fresno and across the Central Valley assume their return is final and optimized. But the reality? Many leave thousands of dollars on the table simply because they didn’t know what they could legally write off—or how to structure it correctly.
At DeMera DeMera Cameron, we see it every year: missed deductions, underutilized strategies, and opportunities that could have significantly reduced tax liability.
One Central Valley contractor came to us after filing their return, assuming everything was handled correctly. After review, we identified over $12,000 in missed deductions. In fact, it’s not uncommon for businesses we review at DeMera DeMera Cameron to uncover $5,000 to $25,000 in missed deductions after filing, often from expenses that were never properly captured or optimized.
Here’s what you should know about tax write-offs in 2026 and what you may have already missed.
What Is a Tax Write-Off (and Why It Matters More Than You Think)
A tax write-off is any legitimate business expense that reduces your taxable income.
Translation? You keep more of your money.
Sounds simple, but this is where most businesses get it wrong…
Common Tax Write-Offs Business Owners Overlook
Even experienced business owners miss these:
1. Vehicle Use (It’s Not Just Gas)
If you use your vehicle for business purposes, you may qualify for deductions through:
- Standard mileage rate
- Actual expenses (gas, maintenance, insurance, depreciation)
Choosing the wrong method can cost you thousands per year, especially for contractors and service-based businesses across the Central Valley.
2. Home Office Deduction (Still Relevant in 2026)
If you run your business from home, you may be eligible to deduct:
- A portion of rent or mortgage
- Utilities
- Internet and office-related expenses
The key? The space must be used regularly and exclusively for business.
3. Equipment, Tools, and Technology
From laptops to heavy machinery, many purchases can be deducted upfront using:
- Section 179 deductions
- Bonus depreciation
This is especially important for industries like construction, where upfront costs are high, and timing purchases strategically can significantly reduce taxable income.
4. Marketing and Advertising (Yes, This Includes Social Media)
This is one that many businesses underestimate; you can typically write off:
- Paid ads (Google, Instagram, etc.)
- Website development
- Branding and content creation
- Influencer partnerships
If you’re investing in growth, those expenses should be working for you at tax time too.
Hiring experts isn’t just smart, it’s deductible.
This includes:
- CPA and accounting services
- Legal fees
- Consultants and advisors
6. “Hidden” Write-Offs Most Business Owners Don’t Realize Count
Here’s where things get interesting…Some of the most valuable deductions aren’t the obvious ones.
Depending on your situation, you may also be able to write off:
- A portion of your cell phone bill (if used for business)
- Health insurance premiums if you’re self-employed
- Retirement contributions like a SEP IRA or Solo 401(k)
These aren’t always top-of-mind, but they can add up quickly, and in some cases, reduce both your taxable income and help you build long-term financial security.
Working with a CPA firm like DeMera DeMera Cameron not only helps you stay compliant but also ensures you’re identifying deductions you may not even know exist.
Industry-Specific Write-Offs (Central Valley Focus)
Different industries have different opportunities.
For example:
- Construction & Trades: tools, subcontractors, job site materials, safety equipment
- Service Businesses: software subscriptions, client management tools, continuing education
- Retail & E-commerce: inventory, shipping, storage, platform fees
Understanding what applies to your specific business model is where real tax savings happen.
Audit-Safe vs. Risky Deductions
Not all write-offs are created equal.
Audit-safe deductions:
- Clearly documented business expenses
- Industry-standard costs
- Properly categorized transactions
Riskier deductions:
- Mixing personal and business expenses
- Overstating home office usage
- Claiming unclear “business” meals or travel

What About 2025–2026 Tax Law Changes?
Recent tax law updates continue to impact how deductions are applied, especially when it comes to depreciation and equipment purchases.
Bonus depreciation had been undergoing a phase-down:
- 100% began phasing out after 2022
- It dropped to 80% in 2023
- 60% in 2024
- 40% in 2025
- and was scheduled to decrease to 20% in 2026 before being eliminated
However, under the One Big Beautiful Bill Act (OBBA), 100% bonus depreciation was reinstated for qualifying assets purchased after January 19, 2025.
This change creates a significant opportunity for businesses to fully expense eligible equipment purchases again, making timing and planning more important than ever.
These changes are outlined by the Internal Revenue Service under current depreciation rules.
In addition, Section 179 expensing limits have increased, allowing businesses to deduct a larger portion of qualifying equipment and asset purchases upfront, subject to annual limits and phase-outs.
What this means for Central Valley businesses:
The timing of your purchases matters more than ever. A piece of equipment purchased in 2024 may be treated very differently than one purchased in 2026 from a tax perspective.
If you’re relying on outdated information, you could be missing opportunities or making costly mistakes.
Already Filed Your Taxes? You Still Have Options
Even if you’ve already filed, you may still be able to:
- Amend your return
- Identify missed deductions
- Adjust future tax strategies
That’s why post-tax season reviews are just as important as filing itself.
FAQs: Tax Write-Offs for 2026
What qualifies as a business expense?
Any ordinary and necessary expense related to running your business may qualify.
Can I still claim deductions if I missed them?
In many cases, yes. You may be able to amend your return depending on timing and eligibility.
Are marketing expenses really deductible?
Yes, most marketing and advertising costs are fully deductible.
Should I track expenses throughout the year?
Absolutely. Waiting until tax season increases the risk of missing deductions.
