2026–2027 IRS and Texas Tax Deadlines
10/15/2026 Federal & C-Corporation Extension Filing Deadline
October 15, 2026 is the final extended filing deadline for taxpayers who filed a valid extension for their federal individual income tax return (Form 1040) and for C-Corporations (Form 1120). Returns not filed by this date may be subject to late-filing penalties, interest, and enforcement actions by the IRS. This deadline applies only to taxpayers who properly submitted an extension request by the original filing deadline.
10/20/2026 Q3 Jul - Sep 2026 Texas Quarterly Sales Tax Filing Deadline
Texas sales and use tax returns and payments for the third 2026 quarter (July – September) are due October 20, 2026. In Texas, sales tax is due by the 20th day of the month after the reporting period; monthly filers file by the 20th of every month. When the 20th falls on a weekend or holiday, the due date moves to the next business day.
Missing a due date can result in penalties, interest, and additional assessment by the Texas Comptroller’s Office. Consult your tax professional if you need clarification on your assigned filing frequency or to set up electronic filing via the Comptroller’s Webfile system for faster processing.
11/16/2026 Texas Franchise Tax Extended Report Deadline
Businesses that filed a second Texas franchise tax extension must file their final 2026 report by November 16, 2026 (November 15 falls on a Sunday). Filing late can lead to penalties, interest, loss of good standing, and forfeiture of the LLC or corporation.
01/02/2027 APEX Opens for the 2027 Tax Filing Season
APEX Income Tax & Multiservice opens for the 2027 filing season (2026 tax year) on January 2, 2027. Book early to gather your documents and get your return prepared as soon as the IRS begins accepting returns. The IRS announces its official e-file opening date each January.
01/15/2027 Q4 2026 Estimated Tax Payment Due
The fourth and final estimated tax payment for the 2026 tax year (income earned September 1 – December 31, 2026) is due January 15, 2027. Self-employed workers, 1099 contractors, gig workers and others without enough withholding should pay by this date to avoid an underpayment penalty.
01/20/2027 Q4 Oct - Dec 2026 Texas Quarterly Sales Tax Filing Deadline
Texas sales and use tax returns and payments for the fourth 2026 quarter (October – December) are due January 20, 2027. In Texas, sales tax is due by the 20th day of the month after the reporting period; monthly filers file by the 20th of every month. When the 20th falls on a weekend or holiday, the due date moves to the next business day.
Missing a due date can result in penalties, interest, and additional assessment by the Texas Comptroller’s Office. Consult your tax professional if you need clarification on your assigned filing frequency or to set up electronic filing via the Comptroller’s Webfile system for faster processing.
02/01/2027 IRS 1099-NEC Filing Deadline (New $2,000 Threshold)
For payments made on or after January 1, 2026, businesses must file Form 1099-NEC for each contractor or other nonemployee service provider paid $2,000 or more during the year, up from the previous $600 threshold. This change was enacted under the One Big Beautiful Bill Act and also applies to certain payments reported on Form 1099-MISC. The IRS says the threshold may be adjusted for inflation beginning in 2027.
Forms 1099-NEC for 2026 payments must be filed with the IRS and sent to each payee by February 1, 2027 (January 31 falls on a Sunday). Penalties may apply if you file late or with errors. Make sure you have a completed W-9 from each contractor before issuing the form.
The higher threshold reduces the number of forms businesses must issue, but it does not change the underlying tax obligation: contractors and freelancers must still report all income they receive, even amounts below $2,000. Businesses should keep accurate records of all payments.
02/15/2027 IRS Refund Holds for EITC & ACTC Claims — 2027 Tax Season
If you claim the Earned Income Tax Credit (EITC) or the Additional Child Tax Credit (ACTC) on your 2026 federal income tax return, federal law (the PATH Act) does not allow the IRS to issue your refund before mid-February 2027, even if your return is accepted earlier. Plan for a refund hold until at least mid-February.
03/15/2027 S-Corporation & Partnership Tax Filing Deadline
For the 2026 tax year, S Corporations (Form 1120-S) and Partnerships (Form 1065) must file their federal tax returns and issue Schedule K-1s by March 15, 2027. File IRS Form 7004 by this date to request an automatic extension to September 15, 2027. An extension to file is not an extension to pay any tax owed.
04/15/2027 Individual & C-Corporation Filing Deadline + Q1 2027 Estimated Tax
April 15, 2027 is the federal deadline for individuals (Form 1040) and calendar-year C Corporations (Form 1120) to file their 2026 returns and pay any tax due. File Form 4868 (individuals) or Form 7004 (businesses) by this date for an extension to October 15, 2027; an extension to file does not extend the time to pay.
April 15, 2027 is also the due date for the first estimated tax payment for the 2027 tax year.
04/20/2027 Q1 Jan - Mar 2027 Texas Quarterly Sales Tax Filing Deadline
Texas sales and use tax returns and payments for the first 2027 quarter (January – March) are due April 20, 2027. In Texas, sales tax is due by the 20th day of the month after the reporting period; monthly filers file by the 20th of every month. When the 20th falls on a weekend or holiday, the due date moves to the next business day.
Missing a due date can result in penalties, interest, and additional assessment by the Texas Comptroller’s Office. Consult your tax professional if you need clarification on your assigned filing frequency or to set up electronic filing via the Comptroller’s Webfile system for faster processing.
05/17/2027 Texas Franchise Tax Annual Report Due
The 2027 Texas franchise tax annual report is due May 17, 2027 (May 15 falls on a Saturday). All entities subject to the franchise tax must file the annual report and the appropriate Public Information Report (PIR) or Ownership Information Report (OIR), even if no tax is due. Franchise tax is only owed if total revenue exceeds the state’s “No Tax Due” threshold, but the annual filing is required regardless of revenue.
Failure to timely file can result in penalties, interest, loss of good standing, and ultimately forfeiture of the LLC or corporation by the State of Texas.
06/15/2027 Q2 2027 Estimated Tax Payment Due
The second estimated tax payment for the 2027 tax year (income earned April 1 – May 31, 2027) is due June 15, 2027.
07/20/2027 Q2 Apr - Jun 2027 Texas Quarterly Sales Tax Filing Deadline
