When are my business taxes due in Texas?

Dates are for a calendar-year business in 2027. A date that falls on a Saturday, Sunday or legal holiday moves to the next business day, for the IRS, the Comptroller and the Texas Workforce Commission (IRS Publication 509; comptroller.texas.gov; twc.texas.gov); the dates below already include that shift.

Form 941 only reports the quarter. Withheld income tax, social security and Medicare are deposited monthly, by the 15th of the next month, or semiweekly, unless the quarter's tax is under $2,500; FUTA is deposited each quarter once it passes $500 (IRS Publication 509). The TWC tax is paid with its quarterly report.

Partnerships file Form 1065 and S corporations Form 1120-S by the 15th day of the third month after their year ends. C corporations file Form 1120 by the 15th day of the fourth month, and sole proprietors report on Schedule C with Form 1040 by April 15 (IRS Publication 509).

Form 7004 gives a partnership or corporation six more months to file, and Form 4868 does the same for a sole proprietor’s Form 1040. An extension does not give more time to pay (Form 7004 instructions; Form 4868), and the IRS charges penalties and interest on a return filed or tax paid late (IRS penalties).

Texas taxes the right to do business, not income. LLCs, corporations and most partnerships are subject to it; sole proprietors and general partnerships owned only by individuals are not (Franchise Tax Overview). The report is due May 15 each year, May 17 in 2027.

A business whose annualized revenue is at or below $2,650,000 for the 2026 and 2027 reports (comptroller.texas.gov) owes no tax and usually files only its information report, Form 05-102 or Form 05-167; above it, the franchise tax report too. Passive entities, REITs and businesses with no Texas receipts file the EZ or Long Form instead, and a qualifying new veteran-owned business files neither for five years (comptroller.texas.gov). The franchise tax guide covers who owes it and how much.

Texas charges 6.25% state sales tax, and cities, counties and transit authorities add up to 2% more, for at most 8.25% (comptroller.texas.gov). In the city of Rockwall the total is 8.25% (city rates).

The Comptroller tells each business by letter, when it approves the sales tax permit, whether it files monthly or quarterly. Monthly returns are due the 20th of the next month; quarterly returns April 20, July 20, October 20 and January 20; and yearly filers report the previous year by January 20. A business with an active permit files every period, even with no sales (permit FAQ). A late return costs $50, and tax paid late adds 5%, or 10% after 30 days (comptroller.texas.gov).

An employer that pays $1,500 or more in wages in a quarter, or has an employee in 20 different weeks of a year, registers with the Texas Workforce Commission within ten days (twc.texas.gov). It files a wage report and pays the tax by the last day of the month after each quarter, including quarters with no wages (twc.texas.gov). A late report or payment carries penalties and interest (due dates). The tax is on the first $9,000 each employee earns in the year, and a new employer’s rate in 2026 is 2.70% (twc.texas.gov).

Counties, cities and school districts tax the equipment, furniture and inventory a business owns on January 1. The owner reports it to the county appraisal district on Form 50-144, the rendition, by April 15. On a written request made by April 15, the appraisal district must extend that to May 15, May 17 in 2027 since the 15th is a Saturday, and it may give 15 more days for good cause (Form 50-144; property tax deadlines; Tax Code §22.23; rendering property).

The first $125,000 of the property at each location in a taxing unit is exempt, for every owner: a business with $160,000 there is taxed on $35,000. Leased-out property, property at locations the owner does not own or lease, and related businesses at one address are combined differently (Tax Code §11.145). An owner at or below $125,000 does not render. It files the form once, certifying that its value is $125,000 or less, and needs no rendition from the next year until its ownership changes, unless the chief appraiser asks for one (Tax Code §22.01). A late rendition costs 10% of the tax on the property. In Rockwall County it goes to the Rockwall Central Appraisal District.

A Rockwall home goods shop is a two-member LLC taxed as a partnership, with five employees. It had $900,000 of revenue in 2026, owned $160,000 of fixtures and inventory on January 1, 2027, and the Comptroller put it on monthly sales tax returns. In 2027 it has:

• February 1: W-2s for the five employees, Form 940, and Form 941 and the TWC wage report for the last quarter of 2026.
• The 20th of every month, or the next business day: a sales tax return for the month before, at 8.25%.
• March 15: Form 1065, or an extension.
• April 15: the rendition listing its fixtures and inventory, since they are worth more than $125,000; it is taxed on $35,000.
• April 30, August 2 and November 1: Form 941 and the TWC wage report for the first three quarters.
• May 17: only the Public Information Report, since $900,000 is under the $2,650,000 threshold.
• April 15, June 15 and September 15, 2027, and January 18, 2028: each member’s own estimated tax.
