What is the deadline for filing my Texas state taxes?

The deadline for filing Texas state taxes is generally April 15th each year. However, if this day falls on a weekend or holiday, the deadline is extended to the next business day. It is important to note that taxpayers who reside outside the United States (including military personnel) have an extended deadline until June 15th without incurring any penalties or interests. To ensure timely filing, it is recommended to utilize electronic filing options, such as the Texas Online Tax Filing system. Additionally, individuals who require more time to prepare their taxes can request an extension until October 15th by filing Form 4868. Nevertheless, even with an extension, any tax liability should be paid by the original deadline to avoid late payment penalties and interests.
