What Are the Biggest Tax Changes for Texas Small Businesses in 2026?

The 2026 tax year brings historic changes affecting how Texas small business owners structure operations and plan taxes. The permanent reinstatement of 100% bonus depreciation is the most significant development. This provision allows businesses to immediately deduct the full cost of qualifying depreciable property acquired after January 19, 2025, rather than spreading deductions over many years.

Previously scheduled to phase out beginning in 2023, this 100% deduction now provides unlimited tax relief for qualifying business assets. Equipment, machinery, software, and certain qualified property all qualify. The impact is substantial: a Texas business purchasing $100,000 in equipment can potentially deduct the entire amount in 2026, reducing taxable income dollar-for-dollar.

Federal Tax Bracket Changes and Standard Deduction Increases

The 2026 standard deduction increased to provide tax relief. For married filing jointly, the standard deduction is $31,500, up from prior years. Single filers receive $15,750, and heads of household get $28,350. These increases benefit business owners who take the standard deduction instead of itemizing.

Additionally, the Social Security wage base rose to $184,500 for 2026. This means business owners paying themselves or their employees above this threshold see 6.2% Social Security tax relief on income exceeding the cap. This is particularly valuable for profitable Texas businesses with multiple employees.

State vs. Federal Conformity Considerations

Texas has no state income tax, which is a tremendous advantage for small business owners. However, federal tax changes may affect how other states treat Texas businesses with multi-state operations. The OBBBA’s 100% bonus depreciation may not be adopted by all states, creating potential state-level tax planning complications for multi-state ventures.

How Does 100% Bonus Depreciation Work for Texas Businesses?

The IRS issued official guidance on the permanent 100% additional first-year depreciation deduction under Notice 2026-11. This applies to eligible depreciable property acquired after January 19, 2025, according to the Treasury and IRS.

How it works: When a Texas business purchases equipment, vehicles, machinery, or software for business use, traditionally the cost must be depreciated over a schedule. A $50,000 vehicle might be depreciated over five years, allowing $10,000 annual deductions. Under 100% bonus depreciation, the entire $50,000 can be deducted in 2026, the year acquired.

Qualifying Property for Bonus Depreciation

• Business vehicles and equipment with original use beginning with your business
• Computer equipment, software, and technology infrastructure acquired for business operations
• Qualified improvement property for commercial buildings and facilities
• Specified plants and trees planted or grafted for business purposes
• Qualified sound recording productions (new category added by OBBBA)

How Bonus Depreciation Combines with Section 179

Many Texas business owners are familiar with Section 179 expensing, which allows immediate deduction of certain business property up to annual limits. Here’s the key advantage: you don’t have to choose between bonus depreciation and Section 179. Both can be used in the same year on different properties.

Bonus depreciation has no annual dollar cap and isn’t tied to business income, so it can generate or increase business losses. Section 179, by contrast, has an annual ceiling and cannot create losses. The strategic advantage: use bonus depreciation for large asset purchases and Section 179 for smaller items within the annual limit.

What Entity Structure Minimizes Taxes for Texas Small Businesses?

Entity selection is perhaps the most critical tax decision for Texas small business owners. Texas imposes no state income tax, which means federal taxation is your primary concern. The analysis changes based on 2026 income levels and business structure.

A sole proprietor with $75,000 annual net business income pays self-employment tax on the full amount, creating roughly $10,600 in additional tax. The same income as an S Corporation with reasonable salary allocation could save $2,000-$4,000 annually through reduced self-employment tax on distributions.

LLC vs. S Corporation Tax Treatment

Texas businesses generating $100,000+ annually should evaluate S Corporation election carefully. Our entity structuring services compare specific scenarios. For many profitable Texas businesses, electing S Corporation status saves thousands annually through reduced self-employment tax while maintaining liability protection.

Which Deductions Reduce Small Business Taxable Income in 2026?

Texas small business owners often miss available deductions, overpaying taxes. The IRS allows deduction of ordinary and necessary business expenses incurred to produce income.

Common Business Deductions for 2026

• Office Expenses: Supplies, equipment, furniture, technology, and internet used for business operations
• Home Office: Mortgage interest or rent, utilities, insurance allocated to dedicated business space (simplified method: $5 per square foot, max 300 sq ft)
• Vehicle Expenses: Mileage at IRS rate, fuel, maintenance, insurance, and lease payments for business vehicles
• Professional Services: Accounting, legal, consulting, bookkeeping fees paid to advisors and firms
• Health Insurance: Self-employed health insurance premiums (deductible as adjustment to income)
• Retirement Plan Contributions: Solo 401(k) or SEP-IRA contributions for self and employees
• Employee Compensation: Wages, payroll taxes, and benefits paid to employees
• Advertising and Marketing: Website costs, social media advertising, business cards, and promotional materials

Documentation and Record-Keeping Requirements

The IRS requires documentation supporting all deductions. Maintain receipts, invoices, credit card statements, and detailed logs for mileage, meals, and entertainment expenses. Inadequate documentation during IRS audit can result in deduction disallowance and penalties.

For vehicle mileage, keep a mileage log documenting business miles driven daily. For home office, maintain square footage documentation and proportional allocation calculations. For charitable contributions or research expenses, keep receipts and beneficiary letters.

How Can Retirement Contributions Lower Business Taxes?

Retirement contributions are among the most powerful tax-reduction tools available. Contributions reduce taxable income dollar-for-dollar in the year made, creating immediate tax savings while building retirement security.

For 2026, the 401(k) deferral limit increased to $24,500 per employee. If you’re age 50 or older, you can contribute an additional $8,000 catch-up contribution, reaching $32,500 total. These contributions reduce both federal and self-employment taxes.

Solo 401(k) vs. SEP-IRA for Self-Employed Business Owners

A self-employed Texas business owner with $100,000 net self-employment income can contribute $24,500 as employee deferral plus approximately $17,000 as employer contribution, totaling $41,500 annual deduction. This reduces taxable income, resulting in $10,000+ tax savings at federal level.

What Are Critical Tax Filing Deadlines for 2026?

Missing tax deadlines triggers penalties and interest. The IRS is strict about filing and payment deadlines, with penalties ranging from 5% monthly for late filing to 25% cumulative penalties for substantial understatements.

2026 Tax Deadline Calendar for Texas Businesses

• January 27, 2026: IRS begins accepting 2025 tax returns for processing and filing
• January 31, 2026: Employers must issue W-2s to employees and file information returns with IRS
• March 16, 2026: Deadline for S Corporation and partnership returns (Form 1120-S and Form 1065) or extension request
• April 15, 2026: Deadline for individual income tax returns (Form 1040) or automatic six-month extension
• June 15, 2026: Quarterly estimated tax payment due for Q2 2026 income (for self-employed and estimated payers)
• September 15, 2026: Quarterly estimated tax payment due for Q3 2026 income
• January 15, 2027: Final quarterly estimated tax payment for 2026 tax year

Texas business owners with estimated tax liability should pay quarterly estimated taxes on June 15, September 15, and January 15 deadlines. Failure to pay estimated taxes incurs penalties even if you ultimately file and pay by April 15.

Uncle Kam in Action: Texas LLC Owner Saves $18,400 Through Entity Restructuring and Retirement Planning

Client Snapshot: Marcus, a Dallas-based management consulting business owner operating as an LLC, generated $150,000 net business income in 2025. He was self-employed with no employees and lacked a formal retirement plan or tax strategy.

Financial Profile: Annual business income: $150,000; no retirement savings; paying approximately 25-30% effective tax rate; previously claiming minimal deductions due to inadequate record-keeping.

The Challenge: Marcus was overpaying taxes significantly. His LLC status meant all $150,000 was subject to 15.3% self-employment tax, creating approximately $21,000 in additional annual tax burden. Additionally, he was missing available business deductions and had no retirement savings strategy. For 2026, he faced the same situation without guidance.

The Uncle Kam Solution: Our team implemented three strategies for Marcus’s 2026 tax year. First, we elected S Corporation status for his LLC, converting it to a pass-through entity that allowed reasonable salary allocation ($60,000) plus distributions ($90,000). This reduced self-employment tax from $21,000 to approximately $8,500, saving $12,500 annually. Second, we established a Solo 401(k) plan, allowing Marcus to defer $24,500 as employee contribution plus $11,250 as employer contribution on the remaining net income, creating $35,750 in retirement savings with full tax deduction. Third, we documented all business deductions including $8,500 in home office expenses, $6,200 in equipment purchases (eligible for bonus depreciation), $3,500 in professional services, and $2,100 in vehicle expenses, totaling $20,300 in additional deductions previously unclaimed.

The Results:

• Self-Employment Tax Savings: $12,500 annual reduction through S Corp status
• Retirement Contribution Deduction: $35,750 reducing taxable income
• Business Deduction Documentation: $20,300 in previously unclaimed deductions
• Projected 2026 Tax Savings: $18,400 total through combined strategies
• Return on Investment (ROI): At $4,500 service fee, Marcus achieved a 4.09x return on investment in the first year alone

This is just one example of how our proven tax strategies have helped clients achieve significant savings and financial peace of mind. Marcus now has a documented tax plan for 2026 and beyond, ensuring compliance while minimizing tax burden.

Frequently Asked Questions

Can I elect S Corporation status mid-year in 2026, or must I elect it at the beginning of the year?

S Corporation elections generally take effect on the date filed or a specified future date. If you file the election by March 15, 2026, it typically becomes effective January 1, 2026. Late elections may require IRS approval and could become effective only partway through the year. Consult with a tax professional regarding your specific situation, as timing significantly affects 2026 tax liability.

What is reasonable compensation for an S Corporation owner-employee in 2026?

The IRS requires S Corporation owners to pay themselves reasonable compensation for services rendered. “Reasonable” typically means comparable wages for similar services in your industry and geographic area. For a management consulting business generating $150,000 net income, reasonable salary might be $70,000-$90,000, with remaining income distributed as qualified distributions subject only to income tax, not self-employment tax. The IRS has been aggressive in disallowing artificially low salaries, so documentation and industry comparisons are critical.

Does 100% bonus depreciation create any alternative minimum tax (AMT) issues for Texas business owners?

For 2026, the alternative minimum tax (AMT) applies to higher-income taxpayers. Large bonus depreciation deductions could theoretically trigger AMT calculations, though most small business owners won’t be affected. High-income business owners should evaluate AMT implications when claiming substantial depreciation deductions. This is one reason professional tax planning is valuable—to ensure strategies don’t inadvertently trigger unexpected tax liabilities.

If my business has multiple owners, how does entity selection change the 2026 tax calculation?

Multi-owner businesses have different options than single-owner operations. An LLC with multiple members can choose pass-through taxation (treating each member’s share separately) or elect corporate taxation. An S Corporation with multiple shareholders requires all owners to pay reasonable compensation for services rendered. Partnership structures require special attention to allocation percentages and basis calculations. Multi-owner entity selection requires careful analysis of ownership percentages, roles, and long-term business plans. Professional guidance is strongly recommended.

Can I claim the home office deduction if I use one room as both office and bedroom?

The IRS requires dedicated business use for home office deduction. A room used exclusively for business qualifies. A multipurpose room does not qualify under regular method. The simplified method ($5 per square foot, maximum 300 sq ft) offers more flexibility, allowing deduction of office space without proving exclusive business use. However, even the simplified method expects regular business use. Documentation of how the space is used and when business activities occur strengthens your position during IRS examination.

What happens if I miss the March 16, 2026 deadline for S Corporation returns?

The IRS assesses penalties for late filing ranging from 5% per month of unpaid tax (maximum 25%) for failure-to-file penalties. You should file immediately upon discovering the miss and pay any taxes owed plus penalties. Requests for penalty relief are possible if you demonstrate reasonable cause. Filing an extension (Form 7004) before the March 16 deadline allows automatic six-month extension to September 15, 2026. Always file extensions before the deadline to avoid penalties.

Is there a difference between Texas tax obligations and federal tax obligations for small business owners?

Texas has no state income tax, which is a tremendous advantage for small business owners. However, Texas does impose other taxes including sales tax (6.25% state rate, 8.25% with local), franchise tax (for certain businesses), and payroll taxes if you have employees. Federal income tax, self-employment tax, and federal employment taxes still apply regardless of Texas location. The no-state-income-tax advantage means business owners should focus on federal tax optimization and sales tax compliance.
