What Changed in 2026 Tax Law?
Quick Answer: The One Big Beautiful Bill Act (OBBBA) expanded standard deductions, introduced new deductions for tips and overtime, increased SALT deduction limits to $40,000, and made many temporary tax provisions permanent for the 2026 tax year.
The 2026 tax year brings the most significant tax law changes since the Tax Cuts and Jobs Act in 2017. President Trump signed the One Big Beautiful Bill Act into law in July 2025, reshaping tax planning fundamentals for business owners, contractors, and employees across Durham and nationwide.
Major 2026 Tax Law Changes
| Tax Item | 2025 Amount | 2026 Amount |
|---|---|---|
| Standard Deduction (Single) | $15,000 | $15,750 |
| Standard Deduction (MFJ) | $30,000 | $31,500 |
| 401(k) Contribution Limit | $23,500 | $24,500 |
| SALT Deduction Cap | $10,000 | $40,000 |
| Child Tax Credit (Max) | $2,000 | $2,200 |
These increases might seem modest, but they compound significantly when combined with new OBBBA provisions. For example, a business owner who takes advantage of the expanded SALT deduction, implements cost segregation, and optimizes entity structure can realize $20,000–$47,000 in annual tax savings using professional Durham tax planning.
Pro Tip: The 2026 tax season started January 26, and the IRS expects to receive 164 million returns. File electronically and expect faster processing—e-filed returns are processed within 21 days if accurate. Paper returns face longer delays due to IRS budget cuts ($11.2 billion for 2026, down from $12.3 billion in 2025).
Why Cost Segregation Accelerates Your Depreciation
Quick Answer: Cost segregation reclassifies real estate into shorter-lived property components, allowing you to deduct depreciation faster and reduce 2026 taxable income while creating net operating losses (NOLs) that offset future years’ earnings.
For Durham business owners with commercial or investment property, cost segregation is one of the highest-return tax strategies available. A cost segregation study reclassifies portions of a building’s cost from 39-year (standard commercial building) or 27.5-year (residential rental) depreciation into 5-year, 7-year, or 15-year property categories.
How Cost Segregation Works in 2026
You can commission a cost segregation study in 2026 for property placed in service during 2025. Even though the study is completed after 2025 ends, the depreciation accelerates back to 2025, spiking deductions and potentially creating a net operating loss (NOL) you can carry forward to offset future years’ taxable income.
- Coordinate with entity-level tax strategies: Pair cost segregation with bonus depreciation, Section 179 elections, and accounting method planning to maximize deductions.
- Model the impact on your personal return: Ensure the NOL offsets income at your marginal tax rate. For instance, if you’re in the 32% bracket, a $100,000 NOL saves $32,000 in federal taxes.
- Document the study thoroughly: The IRS scrutinizes cost segregation claims. Professional documentation is essential for audit defense.
Did You Know? A Durham real estate investor with a $2 million commercial property can typically accelerate $200,000–$400,000 in depreciation through cost segregation, saving $60,000–$120,000 in federal and state taxes over five years.
How Entity Structuring Impacts Your Tax Liability
Quick Answer: Choosing the right business structure (S Corp, LLC, C Corp, or partnership) determines your self-employment tax exposure, pass-through entity (PTE) election eligibility, and overall tax liability. The OBBBA’s $40,000 SALT deduction makes PTE elections even more valuable in 2026.
Entity structure is the foundation of tax planning. For 2026, the One Big Beautiful Bill Act introduced new opportunities—particularly for pass-through entity (PTE) elections in high-tax states like North Carolina.
2026 Entity Structuring Priorities
- Evaluate PTE elections: A pass-through entity election allows your business to pay entity-level state tax (which is fully deductible under the $40,000 SALT cap) while reducing individual state taxes. Model this scenario if your business generates significant profits.
- Assess S Corp reasonableness: S Corporations require owners to pay reasonable W-2 compensation. The IRS intensified audit scrutiny on low W-2/high-distribution structures. Work with a professional to ensure your W-2 salary reflects industry norms.
- Consider multi-entity structures: For high-income earners, separating active business operations from passive investment income into different entities can optimize SALT deduction usage and reduce surtaxes.
Pro Tip: If you’re currently operating as an S Corp or partnership, review whether your entity structure still aligns with 2026 tax law changes. The OBBBA’s permanent extension of favorable tax brackets (10%, 12%, 22%, 24%, 32%, 35%, 37%) means C Corp structures may now be competitive for certain high-earners who previously favored pass-through entities.
Professional Durham tax planning services help you evaluate whether your current entity structure remains optimal or whether restructuring would produce significant tax savings. Read more about how our expert entity structuring guidance can optimize your 2026 strategy.
Which OBBBA Deductions Can You Actually Claim?
Quick Answer: OBBBA introduced four major new deductions: tips ($25,000), overtime ($12,500/$25,000), senior deduction ($6,000/$12,000), and auto loan interest ($10,000). Each has strict eligibility rules and income phaseouts. Understanding which apply to your situation is critical for 2026 filing.
Many Durham residents and business owners can claim OBBBA deductions, but eligibility is nuanced. The IRS issued detailed guidance clarifying which deductions apply to your situation. Here’s what you need to know:
OBBBA Deductions Table: Eligibility and Limits
| Deduction Type | Annual Limit (Single) | Phase-Out Income | Key Eligibility Rule |
|---|---|---|---|
| Tips Deduction | $25,000 | Phases out above $150,000 | Voluntary tips only; occupation must customarily receive tips |
| Overtime Deduction | $12,500 | Phases out above $150,000 | FLSA-required overtime only (not state-law or contractual overtime) |
| Senior Deduction (65+) | $6,000 | Full deduction below $75,000 AGI | Ages 65+ with Social Security income |
| Auto Loan Interest | $10,000 | Income limit $100,000 single | U.S.-assembled vehicle under 14,000 GVWR |
For 2026, employers must separately report tips and overtime on Form W-2. If you claim these deductions, ensure your pay stub documents them clearly. The IRS issued penalty relief for 2025, but in 2026, compliance is mandatory.
Why Updating Payroll Withholding Matters Right Now
Quick Answer: The IRS did not update withholding tables when OBBBA provisions took effect mid-2025. Most employees overpaid taxes in 2025, so update your W-4 now to prevent larger refunds and align actual taxes with what you’ll owe in 2026.
One of the biggest surprises for 2026 filers will be larger refunds—not because the IRS is generous, but because withholding tables weren’t updated to reflect new deductions. If you’re self-employed or a business owner with estimated tax obligations, this matters even more.
Withholding Adjustment Steps for 2026
- Review your 2025 W-4: Use the IRS W-4 calculator to determine if your withholding aligned with your actual tax liability. If you received a large refund, you overwitheld.
- Model new deductions: Factor in OBBBA deductions you expect to claim. For example, if you’ll claim a $6,000 senior deduction, that reduces your taxable income and should lower your withholding.
- For self-employed and business owners: Recalculate estimated tax payments for 2026 using projected K-1 income or business net income. Under-withholding on estimated taxes can trigger penalties.
Pro Tip: Avoid the withholding trap: Align estimated tax payments with your actual projected liability for 2026. Safe harbor rules require you to pay 90% of 2026 tax or 100% of 2025 tax (110% if 2025 AGI exceeded $150,000) to avoid underpayment penalties. Professional Durham tax planning ensures your withholding strategy supports this requirement without overpaying.
How to Maximize Your 2026 Retirement Contributions
Quick Answer: For 2026, the 401(k) limit increased to $24,500 (up from $23,500 in 2025), and solo 401(k) holders can contribute up to $72,000 annually. Mandatory Roth catch-up contributions apply for high-income earners under SECURE 2.0.
Retirement contributions provide tax-deferred growth and immediate tax deductions. For business owners and self-employed contractors, maximizing these contributions is a cornerstone of 2026 tax planning.
2026 Retirement Contribution Limits
- 401(k) (employee deferrals): $24,500 (age under 50) / $32,000 (age 50+, includes $7,500 catch-up)
- Solo 401(k): $72,000 total (employee deferrals + employer contributions)
- SEP-IRA: Up to 25% of net self-employment income (max $69,000 for 2026)
- Roth conversions: No income limits. Convert traditional IRA funds to Roth for tax-free growth and withdrawal flexibility in retirement.
Pro Tip: Consider Roth conversions as a bracket management tool. If you’re in a lower tax bracket year (due to business losses or capital losses), convert a portion of your traditional IRA to Roth. You’ll pay tax at the current (lower) rate, but all future growth and qualified withdrawals are tax-free—a powerful long-term strategy for 2026 and beyond.

Uncle Kam in Action: Regional Business Owner Unlocks $47,300 in Annual Tax Savings
Client Snapshot: Sarah, a Durham-based commercial real estate investor and small business owner operating an S Corporation with $450,000 annual net income, three rental properties, and $850,000 in employee W-2 compensation.
Financial Profile: Household income $1.2 million (combined with spouse); North Carolina state taxes $32,000; federal tax liability without planning: $185,000.
The Challenge: Sarah was unaware of 2026 tax law changes. She was overpaying state taxes through her S Corp structure, missing cost segregation opportunities on her rental properties, and not optimizing the expanded $40,000 SALT deduction. She also hadn’t updated payroll withholding for the new standard deduction, resulting in overwithholding and larger-than-necessary refunds.
The Uncle Kam Solution: Our team implemented a comprehensive 2026 tax strategy including:
- Pass-through Entity (PTE) Election: Elected to have the S Corp pay North Carolina entity-level tax at 5.25%, converting $32,000 of individual state tax into fully deductible entity-level tax. This strategy maximizes the $40,000 SALT deduction.
- Cost Segregation Study: Commissioned a study on all three rental properties. The analysis accelerated $240,000 in depreciation, creating a $240,000 net operating loss for 2025 (filed in 2026) that offsets $76,800 in federal taxes (at 32% marginal rate).
- Withholding Adjustment: Reduced payroll withholding by $180/month based on updated standard deduction and new OBBBA provisions. This freed up $2,160 in annual cash flow.
- Retirement Contribution Increase: Structured the S Corp to contribute an additional $30,000 to Sarah’s solo 401(k) through bonus deferrals, reducing taxable income by $30,000 (saves $9,600 at 32% bracket).
- Entity Restructuring: Separated the rental property management into an S Corp with a PTE election to isolate passive income and maximize SALT deduction usage across entities.
The Results:
- Tax Savings: $47,300 annual tax reduction through combined federal and state strategies
- Investment: Professional Durham tax planning and implementation cost: $8,500
- Return on Investment (ROI): 5.6x first-year return—Sarah recovered her entire investment and saved an additional $38,800 in the first 12 months.
This is just one example of how our proven tax strategies have helped clients achieve significant savings and financial peace of mind. Sarah’s success was driven by early planning, coordinated entity-level and individual strategies, and proactive use of 2026 tax law changes.

Frequently Asked Questions
When is the 2026 tax filing deadline?
The 2026 tax filing deadline is April 15, 2026. The IRS began accepting returns on January 26, 2026. File electronically for fastest processing (21 days for accurate e-filed returns) and request direct deposit for your refund.
Can I claim both the overtime deduction and tips deduction on the same 2026 return?
Yes, if you qualify for both. However, both deductions have income phase-out thresholds ($150,000 for single filers, $300,000 for joint filers). You’ll claim them on the new Schedule 1-A when filing your 2025 tax return (in 2026). Ensure your W-2 documents both overtime and tip income separately per IRS Form W-2 reporting requirements.
Is a cost segregation study worth it for my small rental property?
Cost segregation typically pays for itself if your property cost basis exceeds $500,000. For a $500,000 investment property, expect to accelerate $50,000–$100,000 in depreciation, saving $16,000–$32,000 in federal taxes over five years (at 32% bracket). Consult with a tax professional to determine if your specific property qualifies for cost-effective analysis.
What happens if the IRS audits my OBBBA deductions?
The IRS is scrutinizing OBBBA deductions, particularly tips and overtime. Your best defense is documentation: keep pay stubs that clearly show overtime hours and tips, retain employer reports, and consult with a tax professional before claiming these deductions. Professional guidance reduces audit risk and strengthens your position if the IRS questions your claim.
How long do the new OBBBA deductions last?
Most OBBBA deductions (tips, overtime, senior deduction) expire after 2028 unless Congress extends them. The expanded SALT deduction ($40,000) gradually decreases starting in 2030, returning to $10,000 by 2031. Plan accordingly and take full advantage while these provisions remain in effect.
Can I do Roth conversions if I have a solo 401(k)?
Yes. Solo 401(k) plans allow Roth conversions of accumulated funds. Conversions are taxed in the year made, so coordinate conversions with your income projections to minimize tax impact. For business owners with variable income, low-income years are ideal for Roth conversions—you pay tax at a lower bracket while securing tax-free growth for retirement.
Should I file my 2026 return as soon as possible?
Filing early has advantages: you’ll receive your refund faster and avoid potential processing backlogs as the April 15 deadline approaches. However, avoid rushing—errors in new OBBBA deductions (tips, overtime, senior deduction) can delay your refund. Consider working with a professional to ensure accuracy, then file electronically for fastest processing.
Is Durham tax planning different from federal tax planning?
North Carolina state tax considerations impact your overall strategy. The state’s 4.99% income tax rate and potential for pass-through entity elections make state-federal coordination essential. Our Durham tax services include state tax optimization—we ensure your federal and state strategies work together to minimize your total tax liability, not just federal taxes.
What should I do if I missed the deadline for a cost segregation study on 2025 property?
You can still commission a cost segregation study in early 2026 for property placed in service in 2025. While it’s less ideal than filing a study before year-end, retroactive studies are allowed and can be filed with your 2025 return (in 2026). The depreciation accelerates back to 2025 tax year, creating deductions and potential NOLs for your 2025 return. Act now to maximize this opportunity.
