Important Tax Dates and Deadlines for Tax Year 2023

January 2024 Tax Due Dates

January 16: Estimated Tax Payment for 4th Quarter of 2023 (Form 1040-ES)
January 17: Farmers and Fishermen Pay Estimated Tax for 2023 (Form 1040-ES)
January 23: IRS Begins Accepting and Processing 2023 Tax Returns (Form 1040)
January 31: Due date for employers to send W-2 forms. To ensure you’re able to complete your tax return on time, the IRS requires all employers to send you a W-2 no later than January 31 following the close of the tax year. Generally, this means W-2s get sent by January 31, but you won’t necessarily receive your form by this date.

February 2024 Tax Due Dates

February 15: File Form W-4 to Reclaim Exemption from Withholding for 2023. If you chose to claim an exemption from your employer withholding taxes from your paycheck last year by filing a Form W-4, you’ll need to re-file the form by this date. You would file this exemption request if you anticipate having no tax liability this year and had none in the previous year.
