Tax filing deadline
This is the due date for self-employed individuals—this means you, sole proprietors—to file their 2023 income tax. The tax filing deadline is generally April 15 but can be pushed to the next business day if it falls on a weekend or legal holiday.
Extension request deadline
This is the last day to request an extension to file your individual income tax return. If you won’t be ready to file your tax return by this date, submit an extension request to delay filing your income tax return until October 15. That said, even if you file an extension, you still need to pay any taxes owed by the April deadline.
Quarterly estimated taxes due
This is the due date for your first-quarter estimated tax payments.
IRA and HSA contribution deadline
This is the final day to make contributions to your IRA or HSA for the 2023 tax year.
