Third Quarter Estimated Taxes: The September 15 Deadline

The September 15 estimated tax due date marks the third installment deadline of the year for individuals who do not have enough tax withheld from their regular earnings.

Generally paid using Form 1040-ES, this payment is designed to cover revenue that isn't fully satisfied through standard withholding. If you rely on self-employment income, investment returns, or other sources where taxes are not automatically withheld, staying on top of this third-quarter deadline is an essential part of your financial routine.

Keeping Clear of Underpayment Complications

When you rely on estimated tax payments, it is critical to make this third installment on time. Missing the September 15 deadline can lead to unexpected underpayment issues when it comes time to file your return later in the year.
