Tax Deadline 2024 Extension October 2. For tax year 2023 (filed in 2024), you needed to submit your tax extension request by monday, april 15—the regular tax filing deadline—or face a penalty. The irs encourages taxpayers to file electronically asap.
It’s that time of year, when summer is over and fall begins with kids back in school and vacations ending. Getting an extension gave you more time to file, but it did not give you.
