Based on the search results, the taxes due today cannot be determined as of November 1, 2023. However, here are some important tax deadlines for 2023:

• April 15, 2024: Tax day for individual filers, including employees, retirees, self-employed individuals, independent contractors, and gig workers, unless the date falls on a weekend or holiday or you file Form 4868 seeking an extension until October 15.
• January 15, 2025: Fourth quarter 2025 estimated tax payment due.
• April 18, 2023: Federal tax filing deadline for 2022 tax returns, which was extended from April 15 due to Tax Day falling on a weekend.
• October 16, 2023: Tax day for those who requested a six-month tax extension using Form 4868.
• June 15, 2023: U.S. citizens and U.S. resident aliens living abroad have until this date to file their tax returns and pay any taxes due.

Its important to note that state income tax due dates typically follow the federal deadline, but some exceptions exist. Additionally, estimated taxes are quarterly tax payments usually made by small business owners, freelancers, and independent contractors, and the schedule for estimated tax payments varies throughout the year.
