Running a small business in Houston means dealing with three layers of tax compliance simultaneously: federal, Texas state, and local. None of the three is overwhelming on its own. Together, they’re the single most common reason Houston business owners miss filings, overpay penalties, or operate for years not knowing what they don’t know.

This guide is for the Houston small business owner who wants the whole picture in one place. We’ll walk through every meaningful tax obligation a typical Houston small business faces in 2026, when it’s due, how much it costs, and what happens if you miss it.

I’ve structured this so you can either read it top to bottom or scan to the section you need. The goal: give you a complete mental model of Houston small business tax compliance so you know what’s working, what’s missing, and where to focus.

The Houston small business tax landscape: what’s actually different

Texas businesses get one thing other states don’t: no state personal income tax. That headline gets a lot of attention. But it leaves the impression that Texas is a “low tax” state, which oversimplifies the picture.

What Houston small businesses actually face:

All the federal taxes everyone faces — income tax, payroll, self-employment tax, FICA, FUTA
Texas Franchise Tax — annual entity-level tax that surprises many new business owners
Texas Sales Tax — applies to most retail, restaurant, and many service businesses
Local sales tax overlays — Houston’s sales tax has city and county components that add to the state rate
Texas Unemployment Insurance (SUI) — required for employers
Property tax — among the highest in the country (offset partially by no income tax)
Industry-specific taxes — alcohol, fuel, hotel occupancy, etc., depending on business

The compliance complexity isn’t in any single one of these — it’s in keeping all of them current simultaneously. Houston small business owners who miss filings usually miss them not because they’re complicated, but because they didn’t have a calendar that captured all of them.

Federal tax obligations

Income tax

How your business is taxed at the federal level depends on entity type:

Sole proprietor: Business income flows through Schedule C on your personal 1040. You pay both income tax AND self-employment tax (15.3%) on net profit.
Single-member LLC (default): Same as sole proprietor for tax purposes — Schedule C.
Multi-member LLC / partnership: Files Form 1065. Each partner gets a K-1 reporting their share of income. They pay tax on their personal returns.
S-Corporation: Files Form 1120-S. Income passes through to shareholders via K-1. Major advantage: S-Corp owners can split income between W-2 salary (subject to payroll tax) and distributions (not subject to payroll tax) — saving 15.3% on the distribution portion.
C-Corporation: Files Form 1120 and pays corporate income tax at 21%. Profits distributed as dividends are taxed again at the shareholder level. Generally not optimal for most small Houston businesses.

Estimated taxes: Most Houston small business owners owe quarterly estimated taxes — due April 15, June 15 (it shifts when 6/15 is a weekend), September 15, and January 15. The IRS penalizes underpayment, and the penalty has been running 7-8% annualized in 2025-2026 — meaningful real cost.

Payroll tax

If you have W-2 employees, you owe:

Federal income tax withholding — withheld from employee paychecks, deposited to IRS
Social Security & Medicare (FICA) — 7.65% from employee + 7.65% from employer = 15.3% total on wages up to the annual cap ($168,600 in 2026 for Social Security; no cap for Medicare)
Federal unemployment (FUTA) — 0.6% on first $7,000 of wages = $42 per employee per year
Form 941 — filed quarterly
Form 940 — filed annually
W-2s — issued to employees by January 31
Form 1099-NEC — issued to contractors paid $600+ by January 31

Deposit frequency varies by payroll size. Most Houston small businesses use a payroll provider (Gusto, QuickBooks Payroll, ADP) that handles deposits automatically.

Self-employment tax

For sole proprietors and partners, all business profit is subject to self-employment tax (15.3% — covers both employee and employer portions of FICA). The S-Corp election partially eliminates this tax on distributions. For Houston small business owners earning over $40K-50K from their business, S-Corp election typically saves $2,500-$8,000 per year in payroll tax — even after factoring in the additional administrative costs.

Texas state tax obligations

Texas Franchise Tax

The single most overlooked Texas tax. Applies to most entities formed or doing business in Texas:

What’s taxed: Margin (revenue minus deductions) for entities above the threshold
2026 threshold: $2.47 million annualized revenue. Below this, you owe zero tax but still file a No Tax Due Report.
Rate: 0.375% for retail/wholesale businesses, 0.75% for others
Filing method: Most small Houston businesses use the “No Tax Due Report” or “EZ Computation Report”
Due date: May 15 each year for the prior calendar year
Penalty for late filing: 5% penalty if filed within 30 days late, 10% if later. $50 minimum penalty even on No Tax Due Reports.

The Public Information Report (PIR) must be filed alongside the franchise tax filing. Lists officers, directors, registered agent, and registered office.

The danger: If you go 120+ days past the deadline without filing, the Texas Comptroller can suspend your entity’s “right to transact business in Texas.” This is much more serious than the late filing penalty itself — you can’t legally enter contracts or bring lawsuits in Texas courts until you restore the entity.

For Houston small businesses with multiple LLCs (common for real estate investors and multi-line operators), each entity has its own franchise tax obligation. It’s easy to forget single-purpose holding entities.

Texas Sales Tax

Most retail and many service businesses must collect and remit Texas sales tax:

Texas state rate: 6.25%
Local add-ons: Up to 2% combined city, county, and special district taxes
Total rate in Houston: Usually 8.25% (state 6.25% + Houston city 1% + Metro 1%)
Total rate in Sugar Land: 8.25% (state 6.25% + city/special districts 2%)
Total rate in unincorporated Fort Bend County: 6.75% (state 6.25% + county/special 0.5%)

Filing frequency depends on tax volume:

Annual if your tax liability is under $1,000/year
Quarterly for most small businesses
Monthly if your liability is $1,500+/month

Critical for Houston multi-location businesses: Texas sales tax is destination-based, meaning you charge the rate of the location where the buyer takes possession. A Houston business shipping to Sugar Land charges Sugar Land’s rate. Online businesses with Texas customers have to track rates by ZIP code.

Most small businesses use sales tax automation (TaxJar, Avalara) or their POS system (Square, Toast) to handle the rate complexity.

Texas Unemployment Insurance (SUI)

Employers pay state unemployment tax via the Texas Workforce Commission:

2026 new employer rate: 2.7% on first $9,000 of wages = about $243 per employee per year
Experience-rated after about 3 years — your rate adjusts based on how many of your former employees collected unemployment
Filing: Quarterly via TWC Form C-3
New hire reporting: Texas requires reporting new W-2 hires to the Texas New Hire Reporting program within 20 days of hire

Local Houston tax considerations

Property tax

Texas property tax is among the highest in the country. For Houston small business owners:

Real property (buildings, land) is taxed by the local appraisal district. Harris, Fort Bend, Montgomery, and surrounding counties each have separate appraisal districts.
Business personal property (equipment, inventory, fixtures) is also taxable. Must be reported via annual rendition (Form 22.15 in most Texas counties).
2026 rates vary by location but typically 2.0-2.7% of assessed value.
Appeal deadline: Usually May 15 each year for the assessed value.

The appeal opportunity: Texas appraisal districts often over-assess. Houston small business owners can usually save 5-15% by appealing each year, either personally or via a property tax consultant (typically paid as a 30-40% contingency on year-one tax savings).

Houston hotel occupancy tax

If you operate a hotel, motel, vacation rental, or short-term rental in Houston:

State HOT rate: 6%
City of Houston HOT: 7%
Total Houston HOT: 13% on guest receipts
Other Houston-area cities have their own rates (Sugar Land 7%, Pearland 7%, etc.)

Short-term rental owners (Airbnb, VRBO) in Houston are increasingly being audited for HOT compliance. The platforms remit some taxes automatically; some you still owe directly.

Other local taxes

Alcoholic beverage taxes — Texas Alcoholic Beverage Commission
Fuel taxes — Texas Comptroller, primarily for fuel distributors
Insurance premium taxes — Texas Department of Insurance
Industry-specific permits and licenses — varies by industry

Most small Houston businesses don’t deal with these unless they’re in specific regulated industries.

The compliance calendar at a glance

Here’s a typical Houston small business compliance calendar across the year:

January:

Annual Texas Workforce Commission Wage and Hour reports
Form W-2s due to employees and Social Security Administration (Jan 31)
Form 1099-NECs due to contractors and IRS (Jan 31)
Q4 estimated taxes due (Jan 15)
Q4 payroll tax deposits if monthly schedule

February:

Texas Comptroller business personal property rendition due (varies by county, often Feb 15 or Apr 15)

March:

Annual report filings if applicable
S-Corp and partnership tax returns (Form 1120-S, 1065) due March 15

April:

Personal income tax (Form 1040) due April 15
C-Corp returns (Form 1120) due April 15
Q1 estimated taxes due April 15
Property tax appeal preparation begins

May:

Texas Franchise Tax Report due May 15
Public Information Report due May 15
Property tax appeal deadlines (most counties)

June:

Q2 estimated taxes due (June 15, or next business day)

July:

Q2 payroll tax deposits
Texas sales tax filings if quarterly

September:

Q3 estimated taxes due September 15

October:

S-Corp/Partnership extended deadline October 15
1040 extended deadline October 15

This calendar shows why most Houston small business owners benefit from working with a CPA. Tracking every deadline across all four tax layers is more than most owners can fit alongside running the business itself.

Common Houston small business tax compliance mistakes

After processing hundreds of Houston small business tax situations, the most expensive recurring mistakes:

Missing the Texas Franchise Tax deadline. Most penalized item we see. Even No Tax Due filers can incur the $50 minimum penalty and right-to-transact-business consequences if missed too long.

Misclassifying employees as 1099 contractors. Texas Workforce Commission and IRS both look at this hard. Penalties for misclassification can be 5-50% of unreported tax depending on intent.

Not making the S-Corp election when it would save thousands. Sole proprietors and LLCs taxed as disregarded entities pay full self-employment tax on profits. For Houston business owners earning $40K+ in profit, the S-Corp election typically saves $2,500-$8,000/year.

Under-paying estimated taxes. The IRS penalty has been 7-8% annualized — real money. Houston business owners often underestimate their annual tax bill until April when it’s too late to true up cheaply.

Not tracking sales tax by location. Single-location businesses are simple. Multi-location or online sellers in Texas have to track ZIP-code-level tax rates.

Combining personal and business expenses. Single biggest audit trigger. Houston small business owners commingling expenses lose deductions, trigger audits, and lose credibility.

Not filing the Public Information Report. The PIR must accompany the Texas Franchise Tax filing. Missing it can hold up the franchise filing acceptance even if the tax portion is paid.

Skipping property tax appeals. Texas counties usually over-assess. Houston small business owners leave 5-15% on the table by not appealing annually.

DIY-ing complex returns. TurboTax handles simple Schedule C. It does not handle multi-entity structures, multi-state operations, or complex passive activity calculations. The cost of getting these wrong far exceeds professional CPA fees.

Year-end as the only planning conversation. Tax planning done in December has limited impact. The conversations that change your tax bill happen in June, August, and October.

When to bring in a CPA vs DIY

Honest framework:

DIY makes sense if:

Sole proprietor with under $100K in revenue
Single bank account, simple business model
No employees, no inventory, no real estate
Total annual tax obligation under $5,000

Bring in a CPA when:

Annual revenue exceeds $250K
You have any employees or contractors
You operate as an S-Corp, partnership, or multi-member LLC
You own real estate (rentals, especially)
You operate in multiple Texas locations or states
You’re growing fast and capital decisions matter
Your tax bill exceeds $15,000-$20,000 (the CPA fee is a fraction of the optimization savings)

Bring in a CPA + bookkeeper when:

You’re spending 5+ hours/week on bookkeeping
You have multiple LLCs or entities
Your business has inventory or job costing complexity
You’re approaching $1M+ revenue
Sales tax compliance involves multiple jurisdictions

For Houston small businesses in the right zone, comprehensive CPA + bookkeeping services typically run $7,000-$15,000 per year — usually 1-3% of revenue. The savings in taxes, penalties avoided, and time recaptured typically exceed the fee by 3-10x.
