Video Tips: Third Quarter Estimates Due September 15th

The September 15 estimated tax due date is the third installment deadline for individuals who do not have enough tax withheld during the year, and it is generally paid using Form 1040-ES. This payment helps cover income that is not being fully satisfied through withholding, such as self-employment income, investment income, or other sources where tax is not automatically withheld.

If you rely on estimated tax payments, it’s important to make this installment on time to help avoid underpayment issues later in the year.
