2026 Small Business Tax Guide for Texas
Everything Texas small business owners need to know about federal and state taxes, deductions, deadlines, and strategies — updated for 2026.
Section 1: Texas Business Tax Overview
Texas Has No State Income Tax
One of the most significant advantages of operating a business in Texas is the absence of a state income tax. This applies to both individuals and most business entities, meaning your business profits are not subject to a state-level income tax — a major competitive advantage over states like California, New York, or Illinois.
Texas Franchise Tax
While Texas has no income tax, most businesses are subject to the Texas Franchise Tax, also called the "margin tax." For 2026, the no-tax-due threshold is $2.65 million in annualized total revenue. Businesses below this threshold owe no franchise tax and are not required to file any report — Texas eliminated the No Tax Due Report filing requirement starting with the 2024 report year.

Federal Taxes Still Apply
Texas business owners are still subject to all federal tax obligations. This includes federal income tax on business profits, self-employment tax of 15.3% on net self-employment income (covering Social Security and Medicare), and quarterly estimated tax payments if you expect to owe $1,000 or more.
Texas Sales Tax
Texas imposes a 6.25% state sales tax on most taxable goods and services. Local jurisdictions (cities, counties, transit authorities) can add up to 2% in additional sales tax, bringing the maximum combined rate to 8.25%. If your business sells taxable goods or services, you must collect and remit sales tax and hold a Texas Sales and Use Tax Permit.
Section 2: 2026 Key Tax Deadlines
Missing a tax deadline can result in penalties and interest. Mark these dates on your calendar and work with your bookkeeper or CPA to prepare well in advance.
| Deadline | What’s Due |
|---|---|
| Q4 2025 estimated tax payment due (Form 1040-ES) | |
| W-2s and 1099-NEC forms must be furnished to recipients | |
| 1099s filed with IRS — paper deadline Feb 28, electronic deadline Mar 31 | |
| S-Corporation returns (Form 1120-S) and Partnership returns (Form 1065) due | |
| Individual income tax returns (Form 1040) and C-Corporation returns (Form 1120) due; Q1 2026 estimated taxes due | |
| Q2 2026 estimated tax payment due | |
| Q3 2026 estimated tax payment due; extended S-Corp and Partnership returns due | |
| Extended individual income tax returns due (Form 1040) | |
| Year-end tax planning actions must be complete — retirement contributions, equipment purchases, income deferral strategies |
Section 3: Top 20 Tax Deductions for Texas Small Businesses
Maximizing legitimate deductions is one of the most effective ways to reduce your tax liability. Here are the top 20 deductions available to Texas small business owners in 2026, along with pro tips for each.
Home Office Deduction
If you use part of your home regularly and exclusively for business, you can deduct a portion of your mortgage interest or rent, utilities, insurance, and depreciation. The simplified method allows $5 per square foot up to 300 sq ft ($1,500 max). The regular method calculates the actual percentage of your home used for business.
Pro tip: The space must be used regularly AND exclusively for business — a guest bedroom that doubles as an office does not qualify.
Vehicle Expenses
You can deduct vehicle expenses using either the standard mileage rate (70 cents per mile in 2026, up from 67 cents in 2025) or the actual expense method (gas, insurance, repairs, depreciation). Track every business mile with a mileage log that includes date, destination, and business purpose.
Pro tip: Apps like MileIQ or QuickBooks Mileage Tracker make logging easy and IRS-defensible.
Equipment & Machinery (Section 179)
Section 179 allows you to deduct the full cost of qualifying equipment and software in the year of purchase rather than depreciating it over several years. The 2026 limit is $1.22 million, with a phase-out beginning at $3.05 million in total equipment purchases.
Pro tip: Equipment must be placed in service (actually used) before December 31 — purchasing in December and leaving it in the box may not qualify.
Bonus Depreciation
Bonus depreciation allows an additional first-year deduction on qualifying property. For 2026, the rate is 40% (down from 60% in 2024 and phasing to 20% in 2027 and 0% in 2028 under current law). Unlike Section 179, bonus depreciation can create a net operating loss.
Pro tip: Bonus depreciation applies to used property as well as new — a significant advantage for businesses buying pre-owned equipment.
Health Insurance Premiums
Self-employed individuals can deduct 100% of health insurance premiums paid for themselves, their spouse, and dependents. This deduction is taken on Schedule 1 of Form 1040 and reduces adjusted gross income — not just taxable income.
Pro tip: You cannot take this deduction for any month you were eligible to participate in an employer-sponsored health plan (including a spouse’s plan).
Retirement Plan Contributions
Contributing to a retirement plan is one of the most powerful tax reduction strategies available. SEP-IRA contributions can be up to 25% of net self-employment income, capped at $69,000 in 2026. SIMPLE IRA employee contributions are up to $16,000 ($19,500 if age 50+). Solo 401(k) plans allow both employee and employer contributions.
Pro tip: SEP-IRA contributions can be made up to the tax filing deadline (including extensions) — you can fund a 2026 SEP-IRA as late as October 2027 if you file an extension.
Business Meals
Business meals are 50% deductible when there is a genuine business purpose and the meal is with a client, customer, employee, or business associate. Document the business purpose, attendees, and amount for every meal you deduct.
Pro tip: Keep receipts for all meals over $75. For smaller amounts, a detailed log entry is sufficient — but receipts are always better.
Business Travel
Travel expenses for business trips away from your tax home are fully deductible: airfare, hotels, rental cars, taxis, and 50% of meals. The trip must be primarily for business — if you extend a business trip for personal vacation days, only the business portion is deductible.
Pro tip: Document the business purpose of every trip. A brief note in your calendar or expense report is sufficient.
Professional Services
Fees paid to bookkeepers, CPAs, attorneys, consultants, and other professionals for business-related services are fully deductible. This includes tax preparation fees for your business return.
Pro tip: The cost of this guide’s author — a professional bookkeeper and tax preparer — is a deductible business expense.
Software & Subscriptions
Business software subscriptions (QuickBooks, Microsoft 365, project management tools, industry-specific software) are fully deductible. Annual subscriptions may need to be prorated if they span two tax years.
Pro tip: Keep a list of all recurring subscriptions and review them annually — unused subscriptions are a common source of wasted spending.
Marketing & Advertising
All ordinary and necessary marketing expenses are deductible: website costs, social media advertising, print materials, trade show fees, promotional items, and agency fees.
Pro tip: Website development costs may need to be capitalized and amortized rather than expensed in full — consult your tax advisor.
Education & Training
Education and training expenses that maintain or improve skills required in your current business are deductible. This includes courses, books, seminars, webinars, and professional certifications.
Pro tip: Education that qualifies you for a new career or business is generally not deductible — it must relate to your existing business.
Phone & Internet
The business-use percentage of your phone and internet bills is deductible. If you use your phone 60% for business, you can deduct 60% of the bill. A dedicated business phone line is 100% deductible.
Pro tip: Document your business-use percentage calculation in case of audit. A one-month usage log is generally sufficient to establish a percentage.
Bank Fees & Interest
Business bank account fees, credit card fees, merchant processing fees, and interest on business loans are all fully deductible. Keep business and personal accounts completely separate.
Pro tip: Interest on a loan used for both business and personal purposes must be allocated — another reason to keep finances separate.
Business Insurance Premiums
Premiums for business insurance policies are fully deductible: general liability, professional liability (E&O), property insurance, business interruption insurance, and workers’ compensation.
Pro tip: Life insurance premiums are generally not deductible as a business expense when the business is the beneficiary.
Wages & Contractor Payments
Wages paid to employees are fully deductible, as are payments to independent contractors. Remember to issue W-2s to employees and 1099-NEC forms to contractors paid $600 or more.
Pro tip: Misclassifying employees as contractors is one of the most common — and costly — payroll mistakes. When in doubt, consult a professional.
Rent & Utilities
If you rent office, retail, or warehouse space, the full rent is deductible. Utilities for your business location (electricity, gas, water, trash) are also fully deductible.
Pro tip: If you own your building, you cannot deduct rent paid to yourself — but you can deduct mortgage interest, property taxes, and depreciation.
Startup Costs
New businesses can deduct up to $5,000 in startup costs in the first year, with the remainder amortized over 180 months. Startup costs include market research, advertising before opening, employee training, and professional fees incurred before the business opened.
Pro tip: If startup costs exceed $50,000, the $5,000 first-year deduction phases out dollar-for-dollar — plan accordingly.
Bad Debts
If you use accrual-basis accounting and a customer fails to pay an invoice you already recognized as income, you can deduct the uncollectible amount as a bad debt. Cash-basis taxpayers cannot deduct bad debts because they never recognized the income.
Pro tip: Document your collection efforts before writing off a bad debt — the IRS expects you to make reasonable attempts to collect.
Qualified Business Income (QBI) Deduction
The QBI deduction (Section 199A) allows eligible self-employed individuals and pass-through business owners to deduct up to 20% of qualified business income. This deduction is available to sole proprietors, partnerships, S-Corps, and some trusts. Income limits and restrictions apply for certain service businesses.
Pro tip: The QBI deduction is currently scheduled to expire after 2025 under TCJA provisions unless Congress acts to extend it. As of this writing, extension legislation is under discussion — consult your tax advisor for the latest status.
Section 4: Entity Structure & Tax Impact
The legal structure of your business has a direct and significant impact on how much tax you pay. Here is a comparison of the most common entity types for Texas small businesses.
| Entity Type | Self-Employment Tax |
|---|---|
| Sole Proprietorship | Yes — 15.3% on all net profit |
| LLC (Single-Member, default) | Yes — 15.3% on all net profit |
| LLC (S-Corp Election) | Only on reasonable salary — not on distributions |
| S-Corporation | Only on reasonable salary — not on distributions |
| C-Corporation | No — but subject to payroll taxes on wages |
The S-Corp Election Sweet Spot
When your business net profit reaches approximately $40,000 or more per year, electing S-Corp tax treatment can generate meaningful self-employment tax savings. Here’s how it works: instead of paying 15.3% SE tax on all net profit, you pay yourself a reasonable salary (subject to payroll taxes) and take the remaining profit as a distribution — which is not subject to SE tax. At $80,000 net profit with a $45,000 salary, you could save $3,000–$5,000 per year. At $150,000 net profit, savings of $8,000–$12,000 per year are common. The S-Corp election adds administrative complexity (payroll, separate return, reasonable compensation requirements), so the math must make sense before electing.
Read our full S-Corp guideSection 5: Quarterly Estimated Taxes
If you are self-employed or own a pass-through business, you are responsible for paying your own taxes throughout the year — no employer withholds them for you. Quarterly estimated tax payments are how you fulfill this obligation.
Who Must Pay Estimated Taxes
You must make estimated tax payments if you expect to owe at least $1,000 in federal income tax after subtracting withholding and credits. This applies to sole proprietors, partners, S-Corp shareholders, and self-employed individuals. Employees who also have self-employment income may be able to increase their W-4 withholding instead of making separate estimated payments.
How to Calculate Your Estimated Payments
Prior Year Safe Harbor
Pay 100% of last year’s total tax liability in four equal installments. If your prior year adjusted gross income exceeded $150,000, you must pay 110% of last year’s tax. This method protects you from underpayment penalties regardless of how much your income grows.
90% of Current Year Method
Estimate your current year tax liability and pay at least 90% of it through withholding and estimated payments. This method is more accurate but requires you to project your income throughout the year.
How to Make Payments
The IRS offers two primary electronic payment methods: IRS Direct Pay (free, no registration required, pay directly from your bank account at irs.gov/directpay) and EFTPS — the Electronic Federal Tax Payment System (free, requires registration, allows scheduling future payments). You can also pay by check with Form 1040-ES vouchers, by credit card (fees apply), or through your tax software.
Underpayment Penalty
If you underpay estimated taxes, the IRS charges an underpayment penalty currently calculated at 8% annualized (the federal short-term rate plus 3 percentage points, adjusted quarterly). This is not a one-time penalty but an interest charge on the underpaid amount for each day it was underpaid.
Texas Note
Because Texas has no state income tax, there are no state estimated tax payments required. This simplifies your quarterly obligations significantly compared to business owners in states with income taxes.
Section 6: QuickBooks & Recordkeeping
Good recordkeeping is not just about staying organized — it is a legal requirement and your best defense in the event of an IRS audit. The IRS generally has three years from the filing date to audit a return, but that window extends to six years if income is understated by more than 25%, and there is no statute of limitations for fraudulent returns.
How Long to Keep Records
| Record Type | Keep For |
|---|---|
| Tax returns | Permanently |
| Supporting documents (receipts, bank statements) | 7 years |
| Employment tax records | 4 years after tax due or paid |
| Property records (for depreciation) | Until sold + 7 years |
| Contracts and legal agreements | Permanently or life of contract + 7 years |
What to Keep
- All receipts for business expenses (digital copies are acceptable)
- Bank and credit card statements for all business accounts
- Mileage logs with date, destination, business purpose, and miles
- Payroll records including time sheets, pay stubs, and tax filings
- Contracts, invoices, and purchase orders
- Asset purchase records for anything being depreciated
QuickBooks Best Practices
- Reconcile your bank and credit card accounts every month — do not wait until year-end
- Categorize every transaction correctly using the Chart of Accounts — miscategorization is the most common bookkeeping error
- Keep business and personal finances completely separate — open a dedicated business checking account and business credit card
- Use the QuickBooks receipt capture feature to attach digital receipts to transactions
- Run a Profit & Loss report monthly to catch errors and monitor business health
- Connect your bank feeds but review every auto-categorized transaction — QuickBooks guesses, but you confirm
Common Recordkeeping Mistakes
- Mixing personal and business expenses in the same account
- Missing or incomplete receipts for deductible expenses
- Not tracking business mileage throughout the year
- Waiting until tax season to reconcile a full year of transactions
- Using the owner’s personal credit card for business expenses without tracking
Section 7: 2026 Tax Law Changes to Know
Tax law changes frequently. Here are the key updates and adjustments that affect Texas small business owners in 2026.
Standard Mileage Rate: 70 Cents Per Mile
The IRS increased the standard mileage rate to 70 cents per mile for 2026, up from 67 cents per mile in 2025. This applies to business miles driven in a personal vehicle. The medical and moving rate is 21 cents per mile; the charitable rate remains 14 cents per mile (set by statute).
Section 179 Expensing Limit: $1.22 Million
The Section 179 deduction limit increased to $1.22 million for 2026, with the phase-out beginning at $3.05 million in total equipment purchases. This allows most small businesses to fully expense any equipment purchase in the year of acquisition.
Bonus Depreciation: 40% in 2026
Bonus depreciation continues its phase-down schedule: 40% for property placed in service in 2026, down from 60% in 2024. Under current law, it drops to 20% in 2027 and 0% in 2028. Congress may act to extend or restore 100% bonus depreciation — monitor legislation closely.
QBI Deduction: Scheduled to Expire After 2025
The 20% Qualified Business Income deduction (Section 199A) was enacted as part of the Tax Cuts and Jobs Act of 2017 and is currently scheduled to expire after the 2025 tax year. As of mid-2026, Congress is actively debating extension. Consult your tax advisor for the current status — this is one of the most significant deductions for pass-through business owners.
1099-K Threshold: $600 (Confirm with Your Advisor)
The IRS has repeatedly delayed the implementation of the $600 1099-K reporting threshold for payment processors (PayPal, Venmo, Square, etc.). The threshold was originally $20,000 with 200 transactions. Confirm the current threshold with your tax advisor, as this has been subject to ongoing IRS guidance changes.
SECURE 2.0: Auto-Enrollment Requirements
Under the SECURE 2.0 Act, new 401(k) and 403(b) plans established after December 29, 2022 must include automatic enrollment starting in 2025. Existing plans are not required to add auto-enrollment. Small businesses with 10 or fewer employees and businesses less than 3 years old are exempt.
Retirement Contribution Limits
For 2026, the SEP-IRA contribution limit is $69,000. The SIMPLE IRA employee contribution limit is $16,000 ($19,500 for participants age 50 and older). The 401(k) employee contribution limit is $23,500 ($31,000 for those 50 and older under catch-up contribution rules).
