Running a small business in Houston comes with significant tax advantages — if you know where to look. Many business owners leave money on the table by missing deductions they legitimately qualify for. At Whetzel CPA, we work with Houston small business owners year-round to identify every deduction available and build a tax strategy that keeps more money in your pocket.
Home Office Deduction
If you use a dedicated space in your home exclusively and regularly for business, you can deduct a portion of your rent or mortgage, utilities, insurance, and maintenance costs. The simplified method allows $5 per square foot up to 300 square feet ($1,500 maximum). The regular method calculates the actual percentage of your home used for business, which often yields a larger deduction for Houston homeowners with higher property values and utility costs.
Vehicle and Mileage Deduction
Houston’s sprawling geography means many business owners drive extensively for client meetings, job sites, and errands. For 2024, the IRS standard mileage rate is 67 cents per mile. A business owner driving 15,000 business miles per year can deduct over $10,000. Keep a mileage log or use an app like MileIQ to document your business driving. You can alternatively deduct actual vehicle expenses (gas, insurance, depreciation, repairs) if that method yields a higher deduction.
Qualified Business Income (QBI) Deduction
Section 199A allows eligible business owners to deduct up to 20% of their qualified business income. This deduction is available to sole proprietors, partnerships, S-Corps, and some trusts and estates. For 2024, the full deduction is available to single filers with taxable income under $191,950 and joint filers under $383,900. Above those thresholds, limitations may apply depending on your business type and W-2 wages paid.
Retirement Plan Contributions
Self-employed individuals and small business owners have several powerful retirement savings options that double as tax deductions. A SEP-IRA allows contributions up to 25% of net self-employment income (maximum $69,000 for 2024). A Solo 401(k) allows both employee deferrals ($23,000 plus $7,500 catch-up if over 50) and employer profit-sharing contributions. These accounts reduce your taxable income dollar-for-dollar while building retirement wealth.
Health Insurance Premiums
Self-employed business owners can deduct 100% of health insurance premiums paid for themselves, their spouse, and dependents. This deduction is taken on your personal return (Form 1040, Schedule 1) and reduces your adjusted gross income, which can also lower your exposure to other tax phase-outs.
Equipment and Technology (Section 179)
Section 179 allows you to immediately deduct the full cost of qualifying business equipment and technology purchases rather than depreciating them over several years. For 2024, the deduction limit is $1,220,000. This covers computers, office furniture, software, vehicles used for business (with limitations), machinery, and other tangible business property. Bonus depreciation at 60% for 2024 provides additional write-off opportunities for larger purchases.
Business Meals
Business meals with clients, prospects, or colleagues are 50% deductible when business is discussed during or directly before or after the meal. Keep receipts and document who attended, the business purpose, and the topics discussed. Note that entertainment expenses (sporting events, concerts) are no longer deductible under current tax law.
Professional Services and Education
Fees paid to accountants, attorneys, consultants, and other professionals for business purposes are fully deductible. Continuing education, professional development courses, industry conferences, and trade publications that maintain or improve skills required in your current business are also deductible.
Do Not Miss These Often-Overlooked Deductions
Houston business owners frequently miss deductions for business insurance premiums, bank fees and credit card processing charges, software subscriptions, marketing and advertising costs, office supplies, business licenses, and professional association dues. These smaller deductions add up quickly over the course of a year.

Frequently Asked Questions
What can I deduct as a small business owner?
Common deductions for Houston small businesses: office expenses, advertising and marketing, business meals (50% deductible), business travel, vehicle expenses (mileage or actual), professional services (CPA, attorney, consultants), employee wages and benefits, insurance, rent and utilities, equipment depreciation, training and education, and home office (proportional). Less commonly captured: business use of phone, internet, subscriptions, and education.
How much can a small business deduct without receipts?
Technically, no deductions are allowed without supporting documentation in an audit. However, the IRS allows reasonable estimates for very small expenses (under $75 each for travel) without specific receipts. Best practice: capture receipts for everything via apps like Expensify or via emailed digital receipts. Houston small business owners who get audited and can’t substantiate deductions lose them entirely, often plus penalties.
Can you write off a car for business in Texas?
Yes. Texas business owners can deduct business vehicle expenses using either the standard mileage rate (67 cents/mile in 2026) or actual expenses (gas, insurance, maintenance, depreciation, lease payments). The mileage method is simpler; actual method often deducts more for higher-end vehicles. You must track business miles contemporaneously — reconstructed mileage logs lose IRS audits. Section 179 expensing can deduct up to $30,500 of a heavier business vehicle (over 6,000 lbs) in the first year.
What’s the Section 199A QBI deduction?
Section 199A allows a 20% deduction on qualified business income for pass-through entities — sole proprietors, partnerships, S-Corps, and most LLCs. For Houston business owners under the income thresholds (~$394K for joint filers in 2026), the deduction applies to most business income. Above the threshold, additional limits apply, especially for specified service trades and businesses (SSTBs). The QBI deduction is one of the most valuable small business tax breaks — and one of the most commonly missed.
